阅读理解。     Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. This means we
need more food.
     One way to produce more food is by growing stronger plants. For thousands of years, farmers have made
plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983,
scientists have been able to change plants more quickly by changing their genetic material (遗传物质). Foods
from plants grown in this way are called genetically modified foods (转基因食品), or GM foods.
     By changing the genetic material of a plant, it is possible to make new plants. They make plants which are
strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared (准备), for
example, which stops people from becoming blind.
     Rich countries produce GM food because they are easy to grow and bring in more money. Poor countries
are interested in them because they help produce more food.
     GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way
of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed
people, then hurt them or their children later. But, both rich and poor countries are very interested in their use,
and they are not going to go away. In 2050 we may think differently about them. 1. GM foods are made by _____. A. farmers
B. workers
C. scientists
D. plants 2. What are the good things about GM foods? A. They make plants strong against diseases.
B. They are unnatural.
C. They can help in human diseases.
D. Both A and C. 3. GM foods _____. A. are a quick way to produce food
B. grow in the wild
C. are safe
D. are grown only in rich countries 4. Why do some people not like GM foods? A. They are not useful.
B. They are not helpful.
C. They are not natural.
D. They are not cheap. 5. From the reading we know that _____. A. GM foods will disappear one day in the future
B. GM foods will not disappear in the future
C. people will not be interested in GM food
D. people will have to stop using GM food

     Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers
are letting students have a ball. By sitting on exercise balls instead of chairs, teachers find students" posture
(姿势) and attention improve.
     Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December
2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the
students thought sitting on the balls helped them pay more attention to what they were learning.
     The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company
encourages the use of the balls. And the company educates not only teachers but also students on how to use
them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico (波多黎各) and Japan," says
Witt. "Research shows that sitting on the balls makes them sit up straighter. You can slouch (低头垂肩地坐)
on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That
carries more oxygen (氧气 to the brain (大脑), so the kids have more energy and can focus longer.

     A fish that lives in America can live out. of water for months at a time, similar to how animals got used
to land millions of years ago, a new study shows.
     The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up,
they live. on the land, said Scott Taylor, a researcher in Florida.
     The fish can grow as large as three inches. They group together and breathe air through their skin before
they can find water again.
     The new scientific discovery came during a trip.
     "We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told
reporters by telephone. He said he would make his study on the fish known to the public in an American
magazine early next year.
     In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
     Some other fish can live out of water for a short period of time. The walking catfish found in Southeast
Asia can stay on land for hours at a time, while lungfish (肺鱼) found in Australia, Africa and South America
can live out of water, but only in a not active (活波的) way. But no other known fish can be out of water as
long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian
University.
     More studies of the fish may tell how animals changed over time.
     "These animals live in conditions similar to those millions of years ago, when animals began to move from
water onto land," Wright said.

     For hundreds Of years, scientists have been trying to answer what things have an effect on people"s
emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your
personality, by the actions of others and by events around you. Perhaps you don"t know your emotions
can be influenced by the weather as well.
     People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight
makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural
chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin
D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑)
and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and
Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce
less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes
them feel good. To help the people in these countries feel better, special "sunrooms" with artificial (人
造的) lights have been built. People can go there and get "sunlight" for an hour or two!
     The weather can also affect people"s emotions in other ways. Hot weather can make people angry
because people feel uncomfortable when they are hot. In the same way, rain can make people angry
because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals
which control our brains. Through these ways, the weather can influence our emotions. Sadly, while
the weather can change us, we can hardly change the weather.
1. Which of the following is NOT mentioned as a factor (因素) that can affect one"s emotions?
A. Weather.
B. Actions of others.
C. Personality.
D. Age. 
2. Which of the following is true about vitamin D according to the passage?
A. It is a kind of artificial chemical.
B. It makes us worried by affecting our brains.
C. It is needed by us all to keep fit.
D. It is in the sunlight.
3. What can we infer (推断) from the passage?
A. We feel good when we are in the bright cool weather.
B. We will be happy when we are caught in the rain.
C. All people in Norway and Sweden feel sad in winter.
D. The more vitamin D you have, the happier you"ll be.
4. What may be the best title for this passage?
A. Why Do We Feel Sad?
B. The Weather Influences People"s Emotions
C. People Need More Vitamin D
D. We Can Hardly Change the Weather
