In the college-admissions wars, we parents are the true fighters． We're pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice． I've twice been to the wars, and as I survey the battlefield, something different is happening． We see our kids' college background as a prize demonstrating how well we've raised them． But we can't acknowledge that our obsession is more about us than them． So we've contrivedvarious justifications that turn out to be half-truths, prejudices or myths． It actually doesn't matter much whether Aaron and Nicole go to Stanford．
We have a full-blown prestige panic; we worry that there won't be enough prizes to go around． Fearful parents urge their children to apply to more schools than ever． Underlying the hysteria is the belief that scarce elite degrees must be highly valuable． Their graduates must enjoy more success because they get a better education and develop better contacts． All that is plausible--and mostly wrong． We haven't found any convincing evidence that selectivity or prestige matters． Selective schools don't systematically employ better instructional approaches than less selective schools． On two measures--professor's feedback and the number of essay exams--selective schools do slightly worse．
By some studies, selective schools do enhance their graduates' lifetime earnings． The gain is reckoned at 2-4% for every 100-point increase in a school's average SAT scores． But even this advantage is probably a statistical fluke． A well-known study examined students who got into highly selective schools and then went elsewhere． They earned just as such as graduates from higher-status schools．
Kids count more than their colleges． Getting into Yale may signify intelligence, talent and ambition． But it's not the only indicator and, paradoxically, its significance is declining． The reason:
so many similar people go elsewhere． Getting into college isn't life's only competition． In the next competition--the job market and graduate school--the results may change． Old-boy networks are breaking down． Princeton economist Alan Krueger studied admissions to one top Ph．D． program． High scores on the GRE helped explain who got in; degrees of prestigious universities didn' t．
So, parents, lighten up． The stakes have been vastly exaggerated． Up to a point, we can rationalize our pushiness． America is a competitive society; our kids need to adjust to that． But too much pushiness can be destructive． The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment． One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction． They may have been so conditioned to being on top that anything less disappoints．
Why do parents urge their children to apply to more schools than ever?

In spite of all stories of prosperity in the United States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate． Most acts of violence were committed by young people． 57% of the criminals arrested in 1979 were youths below 25 of age．
Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education,living without a settled home,being parentless,sufferings from other kinds of misfortune, etc．
There are also other factors than material conditions which are responsible for the sharp increase of crime rate． In the first place, some state laws provide a death penalty but some not．Secondly, the Constitution allows every citizen to carry weapons for his own protection． It is therefore possible and easy for anyone in the country to get a gun． Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crime, the details of which are so accurately described that even children know how to duplicate what they have seen or read．
All these have resulted in a high frequency of crimes committed both by professional criminals and by nonprofessional ones in murder, drug smuggling, robbery, etc．
?Besides bad material conditions, __________also leads to the sharp increase of crime rate．

40 years ago the idea of disabled people doing sport was never heard of. But when the annual games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change.
Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had
been asked by the British government to set up an injuries center at Stoke Mandeville Hospital near London. His ideas about treating injuries included sport for the disabled.
In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome, in the same place as the normal Olympic Games. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years Games for the Disabled are still held at Stoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about 40 countries took part.
Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with the other Olympics.
TheGameshavebeenagreatsuccessinpromotinginternationalfriendshipandunderstanding, and in proving that being disabled does not mean you can't enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at Olympic Games for the able-bodied. Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded.

Many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance, were determined by technologists, artisans, designers, inventors, and engineers-use nonscientific modes of thought. This kind of thinking way is different
from science. Many features and qualities of the objects that a technologist thinks about cannot be reduced to unambiguous verbal descriptions; they are dealt with the mind by a visual, nonverbal process. In the development of Western technology, it has been non-verbal thinking, by and large, that has fixed the outlines and filled in the details of our material surroundings. Pyramids, cathedrals, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them.
The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of nonverbal thinking on the machine by continually using an intuitive sense of rightness and fitness.
What would be the shape of the combustion chamber? Where should valves be placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.
Design courses, then, should be an essential element in engineering curriculum. Nonverbal thinking of a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed to entail "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive process and inferior to verbal or mathematical thought. But it is paradoxical that when the staff began the Historic American. Engineering Record wished to have drawing made of machines and isometric views of industrial processes for its historical record of America engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools.
If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations: they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.
What is the relationship between Paragraph 1 and Paragraph 2?

Crash. Shatter. Boom. Crash. Shatter. Boom. Smattering of silly dialogue. Pretty girl screams: "Dad! " Crash. Shatter. Boom. Silly di.,dogue. "DAD!!! " Crash. Shatter. Boom, What? Oh, sorry. We were falling into a trance there.
Which is, dear moriegoer, what may happen to you during Michael Bay's Transformers: Age of Extinction, the fourth Transformers film and lasts 165 minutes, which is precariously close to the three-hour mark that Bay undoubtedly will reach~by our sophisticated calculations, and at thecurrent growth rate, with his sixth instalment.
But let's not get ahead of ourselves. Despite what you've just read, this film will likely be amassive hit because by now, if you're buying a Transformers ticket, you surely know what you'regetting into, and you want more, more, more. And Bay is the Master of More.
Or just take it from the I l-year-old sitting next to me, who reserved any audible judgment he, too was in a trance, though maybe from sugar intake--until the moment he saw a Transformerbecome a dinosaur. Overwhelmed by the pairing, he proclaimed, "That's the sickest thing I'veever seen in my life.'" It was as if peanut butter and jelly had been tasted together for the first time.
This time, there's a whole new human east. Most important, Mark Wahiberg has replaced Shia LaBeouf as well, Main Hmnan Guy.
A significant part of the movie also takes place in China clearly a nod to the franchise's huge market in the country.
In any case, we begin in Paris, Texas, where Cade Yeager (Wahlberg), a struggling inventor, is desperately seeking a big discovery,. He's also a widowed dad, and super-protective (as the movieincessantly reminds us) of his high-school daughter, Tessa (Nicola Pehz, blond and pretty andineffective, though the one-note script does her no favours).
One day, Cade buys a rusty old truck. Examining it back home, he soon discovers it's noneother than Optimus Prime, the Autobot hero, seriously damaged.
As Cade works on fixing him up, his assistant, wisecracking surfer-dude Lucas, has the dumbidea of calling the authorities. What he doesn't know is that the government is plotting to destroyall remaining Autobots in favour of a man-made army of Transtbrmers. He's being helped in thisendeavour by the shadowy KSI Corporation, run by the nasty-but-complicated Joshua Joyce (StanleyTucci).
So now, it's evil humans that pitted against the trustworthy Autobots. So much for gratitude.There's also a subplot involving Tessa and her secret boyfriend, Shane (Jack Reynor, underused),whose Irish accent leads Cade to dismissively call him "Lucky Charms" --at least until the twobond in battle.
The obvious question: Is it too much for its own good? Bay is very talented at all things visual,the 3-D works well and the robots look great. But the final confrontation alone lasts close to anhour. At some point, you may find yourself simply in a daze, unable to absorb any" further action into your brain.
What is the main idea of the last paragraph?

Many people believe the glare from snow causes snow-blindness． Yet, dark glasses or not,they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of "snow light"．
The United States Army has now determined that glare from snow does not cause snow-
blindness in troops in a snow-covered country． Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain． So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at． Finding nothing,hour after hour, the eyes never stop searching and the eyeballs become sore and the eye musclesache． Nature offsets this irritation by producing more and fluid which covers the eyeball． The fluid covers the eyeball in increasing quantity until vision blurs, then is observed, and the result is
total, even though temporary, snow-blindness．
Experiments led the Army to a simple method of overcoming this problem． Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape． Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus． The men following can then see something．Their gaze is arrested． Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape． By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost． In this way the problem of crossing a solid white terrain is overcome．
Snow-blindness may be avoided by__________

What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it.
If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job. Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.
Which subject is supposed to have no direct value for job hunting?

Passage 1
It's one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and run away in fear. This has always been thought to be something that is hard-wired into a mouse s brain.
But now Wendy Ingram, a graduate student at the University of California, Berkeley, has challenged this common sense. She has found a way to"cure" mice of their inborn fear of cats by infecting them with a parasite, reported the science journal Nature.
The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of unborn babies.
However, the parasite's effects on mice are unique. Ingram and her team measured how mice reacted to a cat's urine(尿) before and after it was infected by the parasite. They noted that normal mice stayed far away from the urine while mice that were infected with the parasite walked freely around the test area.
But that's not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection. They no longer reacted with fear to a cat's smell,which could indicate that the infection has caused a permanent change in mice's brains.
Why does a parasite change a mouse's brain instead of making it sick like it does to humans?
The answer lies in evolution.
"It's exciting scary to know how a parasite can manipulate a mouse's brain this way," Ingram said. But she also finds it inspiring."Typically if you have a bacterial infection, you go to a doctor and take antibiotics and the infection is cleared and you expect all the symptoms to also go away."
She said, but this study has proven that wrong."This may have huge implications for infectious disease medicine."
The underlined part "hard-wired" in Paragraph 1 probably means__________.

Passage 1
A lyric is a subjective poem of intense personal emotion whose principal quality is its musical form. Poe, master of the lyric, was led to explain all poetry as the rhythmical creation of beauty in words. Because great poetry is often pure music, haunting melody, and chiming syllables, the reader should not glance through poetry as he read his newspaper or the latest magazine--skipping a word here and a line there, and still hope to get what the author had intended for him. Poetry being music, like all other forms of music, it gains its meaning when interpreted by the human voice.
It is the special function of lyrical poetry to give pleasure through this musical quality no less than through fine contemplation of beauty it inspires--beauty of thought, of feeling, of expression, and of technical skill. But poetry is more than a great pleasure. It should also be an outlet for our own unspoken thoughts and our varied moods. It makes articulate our choked-up passageways of speech, giving adequate expression to our pent-up loves and joys and glories, and furnishes release and relief to our fears, grieves and sorrows. A great poet takes our half-formed thoughts, or suppressed moods, our crushed desires, and needs, and leads them out into the open, endowing them with a harmony, and completeness ...
Great verse can help to vitalize our thinking about the commonplace and elemental in life, and can idealize and give meaning to the simplest things in creation. Listen to Tennyson:
Flower in the crannied wall,
I pluck you out of the crannies,
I hold you here, root and all, in my hand,
Little flower--but if I could understand,
What you are, root and all, and all in all,
I should know what God and man is.

Passage 1
The British Medical Journal recently featured a strong response to what was judged an inappropriately lenient reaction by a medical school to a student cheating in an examination.
Although we have insufficient reliable data about the extent of this phenomenon, its prevention, or its effective management, much can be concluded and acted upon on the basis of common sense and concepts with face validity.
There is general agreement that there should be zero tolerance of cheating in a profession based on trust and one on which human lives depend. It is reasonable to assume that cheaters in medical school will be more likely than others to continue to act dishonestly with patients,colleagues, insurers, and government.
The behaviours under question are multifactorial in origin. There are familial, religious, and cultural values that are acquired long before medical school. For example, countries, cultures, and subcultures exist where bribes and dishonest behaviour are almost a norm. There are secondary schools in which neither staff nor students tolerate cheating and others where cheating is rampant;there are homes which imbue young people with high standards of ethical behaviour and others which leave ethical training to the harmful influence of television and the market place.
Medical schools reflect society and cannot be expected to remedy all the ills of a society. The selection process of medical students might be expected to favour candidates with integrity and positive ethical behaviour--if one had a reliable method for detecting such characteristics in advance. Medical schools should be the major focus of attention for imbuing future doctors with integrity and ethical sensitivity. Unfortunately there are troubling, if inconclusive, data that suggest that during medical school the ethical behaviour of medical students does not necessarily improve;indeed, moral development may actually stop or even regress.
The creation of a pervasive institutional culture of integrity is essential. It is critical that the academic and clinical leaders of the institution set a personal example of integrity. Medical schools must make their institutional position and their expectations of students absolutely clear from day one. The development of a school's culture of integrity requires a partnership with the students in which they play an active role in its creation and nurturing. Moreover, the school's examination system and general treatment of students must be perceived as fair. Finally, the treatment of infractions must be firm, fair, transparent, and consistent.
According to the author, it is important to prevent cheating in medical schools because__________.

Passage 1
Jatenderpal Singh Bhullar, 25, is a guardsman in Britain. On Dec 11, 2012, he became the first Indian soldier to parade outside Buckingham Palace. He said wearing a turban instead of the famous bearskin was "the best moment of his life".
The historical day came as the UK's 2011 census was published. It shows nearly one in seven of the population in 2011 were foreign-born.
The increase in the number of immigrants in the country is especially obvious in London. For the first time in history fewer than half the population of London described themselves as "White British".
The top source of new immigrants to the country is India. Many other immigrants are from Poland, Pakistan, Ireland and Germany.
One major reason for the explosion in the foreign-born population is the accession of 12 countries in the central and eastern Europe to the EU, giving them the right to live and work in the UK, said the office for National statistics, which was responsible for the census.
For many immigrants the UK tends to be a good place for life and work. Kissy Meyer, 25,moved to Nottingham from Germany in 2007.
"The UK is a great place to live because everyone is so sociable. Apart from the heavy drinking, I love the outgoing lifestyle." She told The Sun.
The census results also suggested the English language could be a barrier for immigrants trying to integrate into British society. In 91 percent of households, English is the main language spoken. However, in four percent of British families, no one is brought up speaking English.
"Britain needs to do more to help integrate its immigrant population," the Labor leader Ed Miliband said in a speech in London on Dec 14, 2012.
The future labor government would make proficiency in the English language a key priority,seeking to achieve what he calls a "connected nation" rather than a "segregated one".
"We can only converse if we can speak the same language, so if we are going to build one nation, we need to start with everyone in Britain knowing how to speak English," he said.
The writer's attitude towards the help to make immigrants speak English is__________.

Passage 1
A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road.
The car's sensors check odors inside the car and monitor a driver's sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed' firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver's palm.
Other carmakers have developed similar detection systems. For example, Sweden's Volvo has developed a breathalyzer attached to a car's seat belt that drivers must blow into before the engine will start.
Nissan's new concept vehicle also includes a dashboard-mounted camera that tracks a driver's alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest.
The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology."For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.
The car's seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it's going to register, so we need to study what's the appropriate level for the system to activate," he says.
What has Volvo developed?

Passage 1
Plants and animals that have been studied carefully seem to have built-in clocks. These biological clocks, as they are called, usually are not quite exact in measuring time. However, they work pretty well because they are "reset" each day, when the sun comes up.
Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room lit only by lamps. And we can program the lighting to produce artificial "days",different from the day outside. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of thegn start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks.
It is known and experimented that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The salne experiment has been repeated many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun.
Naturally, people have wondered whether pigeons might have a built-in compass—something that would tell them about the directions of the earth's magnetic field. One way to test that idea would be to see if a pigeon's sense of direction can be fooled by a magnet attached to its back.
With a strong magnet close by, a compass can no longer tell direction.
To test the idea, a group of ten pigeons had strong little magnet bars attached to their backs.
Another group carried brass bars instead which were not magnetic. In a number of experiments,both groups were taken away from home and let go. On sunny days none of the magnet-pigeons was fooled. They were just as good as the brass-pigeons in starting out in the right direction toward home. On cloudy, overcast days, however, with no sun the brass-pigeons chose the right direction,but the magnet-pigeons were in trouble. They later started out in different directions and acted completely lost.
What does the author want to say by citing the last experiment?

Passage 2
That experiences influence subsequent behavior is evidence of an obvious but nevertheless remarkable activity called remembering. Learning could not occur without the function popularly named memory. Constant practice has such an effect on memory as to lead to skillful performance on the piano, to recitation of a poem, and even to reading and understanding these words. So-called intelligent behavior demands memory, remembering being a primary requirement for reasoning. The ability to solve any problem or even to recognize that a problem exists depends on memory.
Typically, the decision to cross a street is based on remembering many earlier experiences.
Practice (or review) tends to build and maintain memory for a task or for any learned material.
Over a period of no practice what has been learned tends to be forgotten; and the adaptive consequences may not seem obvious. Yet, dramatic instances of sudden forgetting can be seen to be adaptive. In this sense, the ability to forget can be interpreted to have survived through a process of natural selection in animals. Indeed, when one's memory of an emotionally painful experience leads to serious anxiety, forgetting may produce relief. Nevertheless, an evolutionary interpretation might make it difficult to understand how the commonly gradual process of forgetting survived natural selection.
In thinking about the evolution of memory together with all its possible aspects, it is helpful to consider what would happen if memories failed to fade. Forgetting clearly aids orientation in time,since old memories weaken and the new tend to stand out, providing clues for inferring duration.
Without forgetting, adaptive ability would suffer, for example, learned behavior that might have been correct a decade ago may no longer be. Cases are recorded of people who(by ordinary standards) forgot so little that their everyday activities were full of confusion. This forgetting seems to serve the survival of the individual and the species.
Another line of thought assumes a memory storage system of limited capacity that provides adaptive flexibility specifically through forgetting. In this view, continual adjustments are made between learning or memory storage (input) and forgetting (output). Indeed, there is evidence that the rate at which individuals forget is directly related to how much they have learned. Such data offers gross support of contemporary models of memory that assume an input-output balance.
From the evolutionary point of view, __________.

Passage 2
NBA centre Jason Collins recently announced he was gay in a cover story for Sports
Illustrated. In other words, he"came out of the closet." This expression for revealing one's homosexuality may seem natural. Being in the closet implies hiding from the outside world, and the act of coming out of it implies the will to stop hiding. But though the closet has long been a metaphor for privacy or secrecy, its use with reference to homosexuality is relatively recent.
According to George Chauncey's comprehensive history of modern gay culture, Gay New York, the closet metaphor was not used by gay people until the 1960s. Before then, it doesn't appear anywhere"in the records of the gay movement or in the novels, diaries, or letters of gay men and lesbians."
"Coming out," however, has long been used in the gay community, but it first meant something different than it does now."A gay man's coming out originally referred to his being formally presented to the largest collective manifestation of prewar gay society, the enormous drag balls that were patterned on the debutante and masquerade balls of the dominant culture and were regularly held in New York, Chicago, New Orleans, Baltimore, and other cities." The phrase"coming out" did not refer to coming out of hiding, but to joining into a society of peers. The phrase was borrowed from the world of debutante balls, where young women"came out" in being officially
introduced to society.
The gay debutante balls were a matter of public record and often covered in the newspaper, so"coming out" within gay society often meant revealing your sexual orientation in the wider society as well, but the phrase didn't necessarily carry the implication that if you hadn't yet come out, you were keeping it a secret. There were other metaphors for the act of hiding or revealing homosexuality. Gay people could "wear a mask" or "take off the mask". A man could "wear his hair up" or "let his hair down", or "drop hairpins" that would only be recognized by other gay men.
It is unclear exactly when gay people started using the closet metaphor, but "it may have been used initially because many men who remained 'covert' thought of their homosexuality as a sort of'skeleton in the closet'." It may also have come from outsiders who viewed it that way. It seems that"coming out of the closet" was born as a mixture of two metaphors: a debutante proudly stepping into the arms of a community and a shocking secret being kept in hiding. Now. the community is the wider community, and the secret is no longer shocking,"Coming out" is a useful phrase, but it need not imply a closet.
What is the main idea of this passage?

The Band That Wasn't
Have you ever wanted to be part of a band as a famous singer or musician? Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous. But just how do people form a band?
Many musicians meet and form a band because they like to write and play their own music.
They may start as a group of high-school students, for whom practicing their music in someone's house is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments. Later they may give performances in pubs or clubs, for which they are paid in cash. Of course they hope to make records in a studio and sell millions of copies to become millionaires!
However, there was one band that started in a different way. It was called the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizers had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough. They had to use actors for the other three members of the band.
As some of these actors could not sing well enough, they had to rely on other musicians to help them. So during the broadcasts they just pretended to sing. Anyhow their performances were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV, the Monkees would play and sing songs written by other musicians. However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music. In the USA they became even more popular than the Beatles and sold even more records. The band broke up about 1970, but happily they reunited in the mid-1980s.They produced a new record in 1996, with which they celebrated their formal time as a real band.

Passage 1
It's one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and run away in fear. This has always been thought to be something that is hard-wired into a mouse s brain.
But now Wendy Ingram, a graduate student at the University of California, Berkeley, has challenged this common sense. She has found a way to"cure" mice of their inborn fear of cats by infecting them with a parasite, reported the science journal Nature.
The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of unborn babies.
However, the parasite's effects on mice are unique. Ingram and her team measured how mice reacted to a cat's urine(尿) before and after it was infected by the parasite. They noted that normal mice stayed far away from the urine while mice that were infected with the parasite walked freely around the test area.
But that's not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection. They no longer reacted with fear to a cat's smell,which could indicate that the infection has caused a permanent change in mice's brains.
Why does a parasite change a mouse's brain instead of making it sick like it does to humans?
The answer lies in evolution.
"It's exciting scary to know how a parasite can manipulate a mouse's brain this way," Ingram said. But she also finds it inspiring."Typically if you have a bacterial infection, you go to a doctor and take antibiotics and the infection is cleared and you expect all the symptoms to also go away."
She said, but this study has proven that wrong."This may have huge implications for infectious disease medicine."
Which of the following statements is true according to the passage?

材料:某教师在进行《我与父母》教学时让学生围绕“父母为我做了哪些事”和“我为父母做了哪些事”进行讨论
学生张某说,自己的妈妈是工程师,为了照顾自己放弃事业在学校附近租了一间房子陪读学生们听了之后很感动。
这时,学生李某提出了异议,他认为这种陪读虽然体现了母爱,但是母亲这种“以孩子为中的做法值得商榷,过于宠爱、溺爱孩子不利于子女的成长。
听完大家的讨论,教师进行了如下总结
“很好,李某看到了我们容易忽视的一面,陪读’的确体现了父母无私的爱,但是这种爱
我们能心安理得地接受吗如果接受,岂不是有些自私而且不利于我们自立自强。父母有父母的工作和事业,我们有我们的学习和生活,在家不能以哪一方为中心,要相互关爱,共建幸福家庭。
问题:结合思想品德课与教学论的相关知识,分析该教师的教学有哪些值得借鉴的地方
