of ice cream, bowls of noodles and plates of meat-all while losing weight?
You might hate me, thinking I have one of those annoyingly good metabolisms(新陈代谢)that just
burn up fat the instant it enters my body. You might wonder if I have an intestinal(肠的)worm, or
perhaps an eating disorder. Or maybe you"d just shrug your shoulders and figure I have a rich fantasy
life.
You"d be wrong.
For my body to finish such a surprising task, I would have to be a mouse. Not just any mouse, but
one lucky enough to be involved in a new study at Baylor College of Medicine in Houston.
After identifying an enzyme(酶)that allows fat to be stored in the body, scientists fed mice without
those enzymes, and found those mice were able to consume far more food than other mice-and still
weigh 10 to 15 percent less.
Best of all, the mice that had no enzymes were in very good health, producing baby mice with no
problem and generally acting like any other mouse. That"s great news for obesity researchers, who think
that scientists may figure out a way to prevent the fat metabolizing(脂肪代谢)enzyme in humans and
control weight gain. And such a pill would be very exciting for many people who are struggling to get rid
of dangerous extra pounds.
But don"t start planning any big dinner just yet. At this point, of course, any pill for humans is but a
twinkle(闪烁) in the eye of every medicine company"s CEO. More tests are to be made, and eventually
humans will be introduced in the test.
But for now, unfortunately, control in diet is still the key.
B. Burning up fat very quickly.
C. Controlling the diet.
D. Having a rich fantasy life.
B. Because the weight losing tests were made on the mouse.
C. Because the mouse has a very good metabolism.
D. Because the author wants to try the food without the enzyme.
B. put on weight
C. became weak
D. could not have baby mice
B. Scientists cannot find the key to identifying the enzyme.
C. Don"t overeat before the test is made on humans.
D. It is unnecessary to control weight at present.
Brian Wansink, a professor at the University of Illinois, says we also eat certain foods because they
make us feel good, and remind us of happy memories. Wansink calls this kind of food comfort food.
For some people, ice cream is a comfort food. For others, a bowl of noodles soup makes them feel
good.
__2__ Professor Wansink believes that we connect food with important times, feelings, and people
in our lives. "When I was a child, my mother made a delicious soup; I loved it. __3__ And it helps me
feel better, " says one of Wansink’s coworkers.
Do men and women choose different comfort foods? Wansink"s research at the University of Illinois
says "yes". In his study, the favorite comfort food for both men and women was ice cream. After this,
men usually preferred hot, savory (香的) foods like soup or noodles. __4__ Men and women like to
eat comfort foods when they are happy, but women eat these foods more when they are sad or worried.
__5__ About 40 percent of the comfort foods in Wansink"s study were healthy main dishes or
soups and vegetables. It shows, says Wansink, that a comfort food can taste good and be good for you.
A. Not all comfort food is junk food.
B. Where can we buy this sort of food?
C. Sweet foods are also their preference.
D. How does a food become a comfort food?
E. Usually, we eat because we are hungry or need energy.
F. Women like sweet things such as chocolate and cookies.
G. Now, I often have this kind of food when I am tired or worried.
health. However, not all know that noise is also a kind of pollution, and that is harmful to humans, too.
People who work and live under noisy conditions usually become deaf. Today, however, scientists
believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of
the workers who print newspapers and books, and who weave cloth become deaf. Quite a few people
living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old people, for these young people like to listen to "pop" music and most of
"pop" music is a kind of noise. Besides, noise produced by jet planes or machines will make people"s life
difficult and unpleasant, or even make people ill or even drive them mad. It is said that a continuous noise
of over 85 decibels can cause deafness.
Nowadays the governments in many countries have made laws to reduce or control noise and make it
less than 85 decibels. In China, the government is trying to solve not only air and water pollution problems but also the noise pollution problem.
B. air pollution
C. harmful pollution
D. noise pollution
B. 10 percent of all the workers in Britain are working in noisy places
C. 10 percent of all the workers in Britain are being deafened by the noise where they work
D.90 percent of all the workers are free from any noise
B. sell newspapers
C. like listening to music
D. often travel by plane
B. of less than 85 decibels
C. of over 85 decibels
D. of only 85 decibels
Drinking alcohol(酒精)is dangerous for kids and teens and sometimes for adults, too.
Alcohol is a drug, and it is the drug most abused by teens. Many kids have their first drink
at an early age, as young as 10 or 11 or even younger.
They may have seen their parents drink or cool advertisements for beer and wine. It"s
easy for a kid to get the wrong message about alcohol. In TV commercials, drinking looks
like a lot of fun, you might see people drinking; and watching sports together or having
a big party.
But alcoholisactuallya depressant (镆静剂 ).That means it"s a drug that slows down
or depresses the brain. Like many drugs, alcohol changes a person"s ability to think,
speak and see things as they really are.
A person might lose his or her balance and have trouble walking properly. The person
might feel relaxed and happy and start crying or have an argument.
When people drink too much,.They might hurt themselves or other people, especially
if they drive a car. Someone who drinks too much also might throw up and could wake
up the next day feeling awful. Drinking too much alcohol can lead to alcohol poisoning,
which can kill a person. Over time, someone who abuses alcohol can do serious damage
to his or her body. The liver, which removes poisons from the blood, is especially at risk."
Because alcohol can cause such problems, teens shouldn"t be allowed to use alcohol,
and people who drink alcohol are not allowed to drive cars.

Disposing(处理)of waste has been a problem since humans started producing it．As more
and more people choose to live close together in cities,the waste-disposal problem becomes
increasingly difficult．
During the eighteenth century,it was usual for several neighboring towns to get together to select
a faraway spot as a dump site．Residents or trash haulers(垃圾拖运者)would transport household
rubbish,rotted wood,and old possessions to the site．Periodically some of the trash was burned
and the rest was buried．The unpleasant sig
hts and smells caused no problem because nobody
lived close by．
Factories,mills,and other industrial sites also had waste to be disposed of．Those located on rivers
often just dumped the unwanted remains into the water．Others built huge burners with chimneys
to deal with the problem．
Several facts make these choices unacceptable to modern society．The first problem is space
Dumps,which are now called landfills,are most needed in heavily populated areas．Such areas
rarely have empty land suitable for this purpose．Property is either too expensive or too close to
residential neighborhoods．Long-distance trash hauling has been a common practice but once farm
areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city
areas is almost nonexistent．
Awareness of pollution dangers has resulted in more strict rules of waste disposal．Pollution of
rivers,ground water,land and air is a price people can no longer pay to get rid of waste．The amount
of waste,however,continues to grow．
Recycling efforts have become commonplace,and many towns require their people to take part．
Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a
city"s reusable waste.
B．Waste Pollution Dangers
C．Ways of Getting Rid of Waste
D．Waste Disposal Problem
B．recycling it
C．burning it
D．throwing it into rivers
B．There is cheap land to bury waste in modern society．
C．It is difficult to find space to bury waste in modern society．
D．Ways to deal with waste in modern society stay the same．
B．warn people of the pollution dangers we are facing
C．call on people to take part in recycling programs
D．tell people a better way to get rid of the waste
Why isn"t Tony Eating? No one knows what Tony does at lunchtime. His friends all gather at the
dining hall where they share stories and eat. They talk about their lives and the things they have seen in
movies or read in books. But Tony doesn"t care about these things, and he doesn"t join them. In fact,
there is only one thing on Tony"s mind -- building the perfect body. And while his friends are chatting
away, Tony is in the gym by himself, lifting weights. Now, he is able to lift more than ever. He has also
measured his arms and legs and weighed himself. He knows he is in the best shape of his life. But it"s not
enough.
People say that women and girls are the ones who have body size issues, the ones who develop
eating disorders, and the ones affected most by the media pressure. It is true that women and girls are
affected more, but the same issues also affect men and boys.
There is more and more media pressure for men and boys to take on the look of the well-muscled
athletes and actors. Males are becoming uncomfortable about their physical appearance and self-image.
Sports, health, and fitness magazines focus on the importance of having muscles and the methods to
obtain those perfect sports bodies. Boys tend to do a great deal of weight training and, if they do not
see immediate results, they often turn to using steroids (类固醇) and vitamins that advertise unbelievable
muscle gain.
The average boy cannot come near meeting the impossible "standard" of the media"s male body
perfection. They are not going to be Arnold Schwarzenegger or some other action star, or have the
well-muscled body of athletes. The most popular magazines carry images of women and men on the
covers that represent about 3 percent of the population. Obviously, that leaves 97 percent who cannot
measure up to that level of a desired body image.
Magazines, especially those aimed at men and boys, spread the "body building" message around.
Advertisements promote weight lifting, body building or muscle toning. The V-shaped body with great
muscles is emphasized as the ideal.
The need to make weight for a sport like boxing can cause eating disorders. The demandfor pills that
give energy and decrease a person"s desire to eat is high among those needing tomake weight.
More and more health-care professionals are starting to realize the degree that boys can be
influenced by body image. One recent study showed that of boys between the ages of 7 and 9, fifty
percent wanted to reshape their body. This percentage (百分比) increases as they reach their teens and
want to take part in sports and impress girls. It is something that can follow you throughout life if you do
not learn to understand that there is more to you than your muscles and body shape.
B. eating his lunch
C. building a perfect body
D. gaining weight
B. to become a healthy actor
C. to use vitamins to keep healthy
D. to obtain perfect sports bodies
B. to play sports
C. to reshape their bodies
D. to have a good body image
B. demands pills
C. cannot measure up
D. is shaped like a V
