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.Satellites travel _____________.

A. in space               B. in the atmosphere

C. above the ground       D. above space

2. 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

3.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

4.The main（主要的）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

Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way -- by studying movements of random floating garbage. A scientist with many years’ experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.

Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.

The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1, 600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.

As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.

1.Ebbesmeyer phoned the shoe company to find out _____________.

A. what caused the shipping accident

B. when and where the shoes went missing

C. whether it was all right to use their shoes

D. how much they lost in the shipping accident

2.How did Ebbesmeyer prove his assumption?

A. By collecting information from beachcombers.

B. By studying the shoes found by beachcomber.

C. By searching the web for ocean currents models.

D. By researching ocean currents data in the library.

3.Ebbesmeyer is most famous for ___________________.

A. traveling widely the coastal cities of the world

B. making records for any lost objects on the sea

C. running a global currents research association

D. phoning about any doubtful objects on the sea

4.What is the purpose of the author in writing this passage?

A. To call people's attention to ocean pollution.

B. To warn people of shipping safety in the ocean.

C. To explain a unique way of studying ocean currents.

D. To give tips on how to search for lost objects on the beach.

In the last year, China has sent up many ______ satellites, _______ a weather satellite, a science satellite, a TV satellite and so on.

高一英语单项填空简单题查看答案及解析

Satellites(卫星) are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．

Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．

We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator（赤道）．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit（轨道），So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash（撞）into each other．

1.Which of the following is NOT done by satellites according to the passage?

A．Sending information for weather forecast．

B．Taking photographs of the Earth．

C．Sending TV pictures．

D．Providing food for airplane pilots．

2.What’s the speed the earth rotates at?

A．35,880 kilometers per hour．

B．335,880 kilometers per hour．

C．11,000 kilometers per hour．

D．110,000 kilometers per hour

3.Why does the satellite move around the world at the same speed as the Earth rotates?

A．In order to take photographs．

B．In order to stay in a certain position in the orbit．

C．In order to move away from its orbit．

D．In order to send television pictures．

4.What does the underlined word “This” in the 3rd paragraph refer to?

A．A satellite．

B．A little rocket．

C．A satellite seems to stay in the same place in the sky．

D．The satellite puts the rockets in the right position．
