阅读理解。     Now satellites are helping to forecast (预报) the weather. They are in space, and they can reach any
part of the world. The satellites take pictures of the atmosphere (大气), because this is where the weather
forms (形成). They send these pictures to the weather stations. So meteorologists (气象学家) can see the
weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
     Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive
new pictures, the meteorologists compare (比较) them with earlier ones. Perhaps they may find that the clouds
have changed during the last few hours. This may mean that the weather on the ground may soon change, too.
In their next weather forecast, the meteorologists can say this.
     So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists
could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days.
Soon, perhaps, they may be able to forecast the weather for a week or more ahead (提前). 1. Why do we use the weather satellites to take pictures of the atmosphere? Because _______. A. the weather satellites can do it easily
B. clouds form there
C. the weather forms there
D. the pictures can forecast the weather 2. Meteorologists forecast the weather _______. A. when they have received satellite pictures
B. after they have compared new satellite pictures with earlier ones
C. before they received satellite pictures
D. during they study satellite pictures 3. Maybe we"ll soon be able to forecast the weather for _______. A. one day
B. two days
C. five days
D. seven days or even longer 4. The main idea of this passage is that satellites are now used in _______. A. taking pictures of the atmosphere
B. receiving pictures of the atmosphere
C. doing other work in many ways
D. weather forecasting

felt. Only a few big ones hurt people.
     Many earthquakes happened in China, such as the big one is Sichuan last year. Thousands of people died
in it. So it"s important to know what to do when one hits. Here are some tips on how to stay safely in an
earthquake.
     If you are indoors during an earthquake, hide under a desk. Stay away from windows and anything that
could fall on you.
    If you are outdoors, move to a clear place. Try to be away from trees, signs, buildings and streetlights.
These could fall on you.
     If you are in a shop and far from the door, don"t try to run to outside and rush for exits (出口). Everyone
will be doing that and you"ll find it hard getting out. Don"t get into a lift during an earthquake. Just hide under
some strong covers near you.
     When an earthquake has ended, be careful because after-shocks may still happen. These are just as
dangerous as the earthquake itself. So stay under the desk until you make sure it"s safe to get up.
     If you are at home and you smell gas, open the windows and get out of the building as quickly as you can.
A gas line in your house may be broken. This could be very dangerous. 1. Most earthquakes are too _____ to hurt people. A. strong

     For most students, the time of exams is very stressful and difficult. Some students find the exam time
is so bad that they become ill, because they are afraid of failing, and they are afraid of letting their parents
and families down. If exams are really making you ill or worried, don"t hide your feelings. Talk to someone
about it. If he or she doesn"t help you, ask someone else.
     Here are some top tips given by educational psychologists (教育心理学家):
     (1) Ask a teacher about how to revise and about exam skills- how to work when you are in an exam.
     (2) Take a short rest during your time of work and revision. If your mind is tired, it will not remember
well.
     (3) Revise at the time when you know you will work at your best.
     (4) Get enough sleep, and eat healthy food.
     (5) If you feel bad, talk to someone about your worries. But don"t be too relaxed! Some stress over
exams makes you work hard for them.
     (6) If it upsets you to talk to your friends about an exam when it is finished, don"t do it! In fact, don"t
even think about the exam you have finished. What is done has been done. You cannot change what you
have written!
     (7) If you are studying in the evening, don"t go straight to bed afterwards. Your mind will still be "going
round and round"- thinking too much. So something else, maybe walk or get exercise. Choose something
that will relax you, and make you think of other things.

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草). The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until"it is dead. Then, the plant covers the fly. Slowly,the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn"t have all these important things, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need.
