Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare 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.

| D．during they study satellite pictures |
| A．one day | B．two days |
| C．five days | D．seven days or even longer |
| A．taking pictures of the atmosphere |
| B．receiving pictures of the atmosphere |

The idea of a ‘body clock’ should not be too because the lives of most living things are controlled by the 24-hour night-and-day cycle (循环). We feel and fall asleep at night. We become and energetic during the day. Most people will have a bad feeling if the 24-hour cycle is . For example, people who are not used to working at night can find that lack (缺少) of sleep causes them to badly at work.
the daily cycle of sleeping and waking, we also have other cycle which lasts longer than one day. Most of us would that we feel good on some days and not so good on others; sometimes our ideas seem to be so active and at other times, they are not.

Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked（渗漏）out of the ground. Today, however, we have many ways of finding oil. One tool measures（测量）the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves（声波）. Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them.
We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this “black gold”.
小题1:Which of the following isn’t the way to help find oil?
| A．Sound waves travel through different kinds of rocks at different speeds. |
| B．People measure the pull of gravity to know if there is oil. |
| C．Sound waves tell us where the oil has leaked out of the ground. |
| D．People know there is oil if it leaks out of the ground. |
| A．Oil was firstly found by measuring gravity. |
| B．Many things are made from oil. |
| C．We will never run out of oil. |
| D．Our lives would not be different if we didn’t have oil. |
| A．many things are made from oil |
| B．we must find new ways of looking for oil |
| C．people spend a lot of time looking for oil |
| D．oil is important for us but hard to find |
"In that case, be careful and don"t worry. You are very clever," the agent said." Take 5,000 dollars more," Mike looked around uneasily but took the money.
Mike was a clerk in a large company. A few years ago he started to get very worried because it was very hard for him to support his family. He wanted to give his child an excellent education and a bright future, but the future looked rather hopeless.
One day some agents called him. They were his company"s competitors. At first he refused their offers. But when he thought his dream could come true, he agreed to their offers and began giving them information.
However, his spy work started to get more and more difficult because his owner had become suspicious, since a lot of important information was leaking out.
One night when Mike was on one of his spying tasks, he met Alim, the night watchman." What are you doing here, Mike?" shouted Alim.
"Oh, I had just forgotten some documents here, Alim, "Mike replied, trying to look comfortable." I just came to get them."
"Is that true?" Alim said." We’ll see what Mr. Smith says."
Alim called Mr. Smith and told him to come right away. Mr. Smith looked at Mike and said. "So you are the thief! I believed in you, Mike."
"Call the police, Alim. We have finally caught the spy," Mr. Smith said. "And by the way, Mike ,no man can serve two masters. You should have left if you did not work with us any longer."

| A．he didn"t want to work for his company any longer. |
| B．some agents forced him to do so. |
| C．he wanted to give his child an excellent education and bright future. |

Now, an hour before classes start, every seat in the library is taken by students who cannot wait for getting online. Fifth-grade teacher Jen Friday talks about different kinds of birds as students view them at a colorful website. After school, students on buses pull laptops from backpacks to get started on homework. Since the computer arrived, enrollment is up 20%. Scores on state tests are up 35%.
Indeed, school systems in rural Maine and New York City also hope to follow Arace Middle School’s example. Governor Angus King had planned using $50 million to buy a laptop for all of Maine’s 17,000 seventh-graders – and for new seventh-graders each fall.
In the same spirit, the New York City board of education voted on April 12 to create a school Internet portal（入口）, which would make money by selling ads and licensing public school students. Profits（盈利）will also provide e-mail service for the city’s 1.1 million public school students. Profits will be used to buy laptops for each of the school system’s 87,000 fourth-graders. Within nine years, all students in grades 4 and higher will have their own computers.
Back in Bloomfield, in the meantime, most of the kinks have been worked out. Some students were using their computers to visit unauthorized（非法的）websites. But teachers have the ability to keep an eye on where students have been on the Web and to stop them. “That is the worst when they disable you,” says eighth-grade honors student Jamie Bassell. The habit is rubbing off on parents. “I taught my mom to use e-mail,” says another eighth-grader, Katherine Hypolite. “And now she’s taking computer classes. I’m so proud of her!”
小题1:The example of Carmen Arace Middle School in the passage is used to ______.
| A．show the problems schools are faced with today |
| B．prove that a school without high enrollment can do well |
| C．express the importance of computers in modern education |
| D．tell that laptops can help improve students’ school performance |
| A．enjoy e-mail service in the near future |
| B．make money by selling ads on websites |
| C．all have their own laptops within nine years |
| D．become more interested in their studies with laptops |
| A．plans | B．projects | C．problems | D．products |
| A．a school Internet portal is the key to a laptop program |
| B．the laptop program also has a good influence on parents |
| C．students slowly accept the fact their online activities controlled |
| D．the laptop program in public school is mainly for the eighth-graders |
