Mad Scientist Stereotype Outdated
Do people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed？ The Institute of Physics set out to find out whether the stereotype of a physics 'boffin' (科学家)still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong. The majority of people pick-ed a white male of around 60, wearing glasses and with a white beard.
While this stereotype may have been the image of an average physicist fifty years ago, the reality is now very different. Since 1960 the number of young women entering physics has doubled and the average age of a physicist is now 31.
The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting by blackboards full of equations (等式) or working with fizzing (嘶嘶响) test tubes. These stereotypes are really damaging to society. Very good school children are put off studying science because they don't see people like themselves on television or in magazines doing science. They simply don't relate to the media's image of the mad scientist.
This is one reason why fewer young people are choosing to do science at university. If we want to encourage more young people to study science subjects, we need to change this image of the scientist and make science careers more attractive. But we must also develop children's interest in science.
In an attempt to change this negative image, an increasing number of science festivals are being organized. Thousands of people from secondary schools are also encouraged to take part in nationwide science competitions of which the most popular are the national science Olympiads. Winning national teams then get the opportunity to take part in the International Science Olympiads which are held in a different country every year. These events are all interesting for the young people who take part but they only involve a small proportion of students who are already interested in science. It seems that there is a long way to go before science becomes attractive as subjects like computer studies or fashion and design.
第 16 题 Most people have similar ideas of what a physicist looks like.

Different Stages of Sleep
A scientist who has spent many years studying sleep was asked this question: "Why do we need sleep？" His answer was."If we do not sleep, we get very sleepy, "No one knows exactly why we sleep．But scientists have learned a lot．From．sleep experiments, scientists have [earned that there are four different stages 0f sleep;
When you first fall asleep, your heart starts to beat more slowly and your breathing slows down．If something wakes you, you might not think that you had been asleep．Some people call this kind of sleep dozing (打盹)．Scientists call it Stage 1 sleep.
Next, if you are no,t awakened, you drift into a deeper sleep．Your pu!se and breathing become even slower than they were during Stage 1 sleep．But you can still be awakened quite easily．If you take a catnap (小睡，打盹), you probably will not get any further than this stage of sleep, which is called Stage 2.
If you sleep longer than about twenty minutes, you go into the third stage of sleep.Your body is very relaxed．It would take a loud noise to wake you up.
You have probably heard of people who walk in their sleep．No one knows what
makes people sleepwalk (梦游)．But a person can sleepwalk only during Stage 4．This is the deepest kind of Sleep．I{ someone wakes you up during Stage 4, you might, feel very confused．It might take you a few minutes to get used to being awake.
After about ten minutes of Stage 4 sleep, you go back to Stage 3 and then to Stage 2.Then, something quite different begins.to happen．Your heartbeat becomes rapid．Your eyelids flutter (跳动), and your eyes move．This stage of sleep is called REM (rapid eye movement) sleep.
Most dreams happen during REM sleep． Scientists who study sleep often make noisesor talk to sleeping people in the REM stage．They are trying to find out what effects noises can have on dreams． As sleep research continues, scientists might also learn what causes dreams and how dreams might be helpful to people.
第 31 题 According to the author, why do we need sleep？
A．If we do not sleep, we get very sleepy.
B．Because there are four different stages of sleep.
C．No one knows the cause.
D．It is not mentioned in the article.

Passage Two
I don’t ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-time and the nature of black holes.
At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement—jobs, research papers, awards—was viewed through the lens of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.
Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations: I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist？ After all, I don’t study sociology or political theory.
Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me how may of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.
62. Why doesn’t the author want to talk about being a woman scientist again？
A) She feels unhappy working in male-dominated fields.
B) She is fed up with the issue of gender discrimination.
C) She is not good at telling stories of the kind.
D) She finds space research more important.

Why do People Shrink？
Did you ever see the movie Honey, I shrunk the kids？ It's about a wacky(乖僻的) dad (who's also a scientist) who accidentally(偶然的) shrinks his kids with his homemade miniaturizing(使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size.
_________ (1)It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can't be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all？
_________(2).As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. _________ (3).But perhaps the most common reason why some older people shrink is because of osteoporosis.
Osteoporosis(骨质疏松症) occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. _________ (4).Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people –especially women, who generally have smaller and lighter bones to begin with-are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit.
Did you know that every day you do a shrinking act？ You aren't as tall at the end of the day as you are at the beginning. _________ (5).Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again.
