阅读理解。     Do you get enough sleep? With so much homework it"s often difficult to get the rest you need. But you
need to try, because sleep keeps you healthy and it stops you getting fat. Recently, a group of U. S. scientists
did a study (研究) of kids aged between 8 and 13. The study found that if kids sleep for just one extra
(额外的) hour each day, the chance of their getting fat is cut by about 30 percent.
     Why? When people don"t get enough sleep, they become tired. When they are tired, they don"t exercise
enough. Also, kids like snacks. If they are awake (醒着的) an extra hour or two each day, they have more
time to eat snacks or other unhealthy foods.
     So, how much sleep should you get? Scientists suggest 10 to 11 hours a night for kids aged 5 to 12. For
older kids, eight to nine hours will do. 1. How many reasons are given why people might get fat without enough sleep? A. 3.
B. 2.
C. l.
D. None. 2. If you are under 10, how long do the scientists advise you to sleep? A. 10 to 11 hours.
B. 8 to 9 hours.
C. 8 to 13 hours.
D. As long as possible. 3. Where was the study done by the scientists? A. In China.
B. In Britain.
C. In America.
D. In Japan. 4. What does "eight to nine hours will do" mean?  A. Eight to nine hours" sleep will be good and enough.
B. Eight to nine hours" sleep will be too long.
C. Eight to nine hours" sleep will help get fat.
D. Eight to nine hours" sleep will help eat snacks and unhealthy foods.5. What does the passage talk about? A. How to get long sleep.

     About 130 years ago, Thomas Edison of the US invented the light bulb (电灯). Edison"s bulb has turned
night into day ever since. But today, many want to turn the light off.
     The European Union (欧盟) recently decided that by 2009, people should stop using the Edison-style light
bulb. Instead, they should use compact fluorescent lamps (小型荧光灯, CFLs节能灯).
    "CFLs save energy and last longer. They can save money in the long run," said a British official. CFLs use
67 percent (67%) less electricity than the older bulbs. They last up to 10 times (倍) longer. Scientists say that
if everyone used CFLs, electricity use would be cut by 18 percent. There would also be much smaller amounts
of greenhouse gases (温室气体) given off.
     But it"s difficult to make people change their lighting habits. First the CFLs are more expensive. They cost
eight times the price of the older bulbs. Many people don"t like the CFL bulb. They find it too bright. You
cannot change the light of a CFL, either.
     CFLs have been around for several years. However, the older lights still make up about two-thirds (2/3) of
total (全部的) light bulb sales.
(     )1. Thomas, Edison invented the CFL bulb 130 years ago.
(     )2. Countries in the European Union will not use Edison-style bulbs by 2009.
(     )3. Using CFLs helps protect the environment.
(     )4. If you get an older bulb for l Euro (欧元), the CFL bulb will cost you 8 Euros.
(     )5. CFLs have been widely used instead of the older bulbs for several years.

     The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters
long and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that they are
in danger and raises money to save them.
     The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The
main reason why pandas are endangered is that the area where pandas can live has become smaller.
     The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to
increase the size of panda reserves (自然保护区). Some reserves need to be joined together by planting
bamboo between them to make "corridors". These are paths that lead from one reserve to another. No one may
harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look
for food. ②People are working very hard to make sure the giant panda does not die out.
