Now satellites are helping to forecast(預(yù)報(bào))the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, because this is where the weather forms. They send these pictures to the weather stations. So meteorologists(氣象學(xué)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 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.

A.when they have received satellite pictures
B.a(chǎn)fter they have compared new satellite pictures with earlier ones

Learning about the environment is very important. There are many good books that will help you learn. To get started, ask your teacher or your friends for some advice. You can also look at some good websites with information about the environment and climate change. Climate change may be a big problem, but there are many little things we can do to make a difference.
Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy by sharing a car. For example, four people can ride together in one car instead of driving four cars to work. Whenever we use electricity, we put greenhouse gases into the air. By turning off the lights, the television, and the computer when they aren’t needed, you can help a lot.
Don’t buy products (產(chǎn)品) that use too much energy. Some products, like certain cars, are made specially to save energy. These cars can travel longer on less gasoline (汽油). They don’t pollute as much, either. Products like computers, TVs and VCRs with the ENERGY STAR label (標(biāo)簽) are made to save energy. Buying products with these labels will help protect the environment.
Buy recyclable (可循環(huán)再用的) products instead of non-recyclable ones. Recyclable products are usually made out of things that have already been used. It usually takes less energy to make recyclable products than to make new ones. So when you go shopping, look for the recycle mark on the package. The less energy we use, the better.
小題1:The passage is mainly about ________________.
A.some suggestions about cars
B.a(chǎn)n advertisement
C.the changes to the climate
D.the ways to protect the environment
小題2:From the passage, we can learn that ________________.
A.turning off the electricity when it isn’t needed can do good to the environment
B.electricity won’t cause great trouble to our environment
C.cars using less energy will not put greenhouse gases into the air
D.recyclable products are marked with the ENERGY STAR label

Reading comprehensionA. Choose the best answer. (12分)

Letter A
To the Editor:
Why do our children have 11 weeks of summer vacation? Many years ago, 85 percent of Americans worked on farms. Children needed summer vacation because they helped with the farm work. Today only 3 percent of Americans work on farms. But our children still have long summer vacations.
American students lose one or two months of learning during their summer vacations. Away from school for so many weeks students forget what they learned. Experts say that students lose maths skills and reading skills. At the beginning of school in September, teachers have to review last year’s studies for the first four to six weeks of school.
Summer vacations are not great opportunities for learning. Most parents work outside of the home. They can’t be with their kids during the long summer months. Some families can pay for summer camps, but many can’t. Most children stay home and watch TV. They are bored. Most children do not learn new skills during the summer.
James, Teacher
    Letter B
To the Editor:
I am against a longer school year. I believe people learn everywhere, not just in school. I believe children gain experience in the world. Summer vacation is a great opportunity. Kids can discover the world outside of school. They can learn to do things they can’t learn in a classroom. They can learn to swim and ride bikes. They can travel or go to summer camps. They can take time to do things like cooking and art. Some can get summer jobs. They can get work experience or help people in the community. They can spend time with people of other ages. Basically, they can get more experience in the world.
Long summer vacations give families time together. During the school year, everyone is busy. During summer vacations, we take time to do things together. Vacations are good for families.
Linda, Parent

Carmen Arace Middle School is situated in the pastoral town of Bloomfield, Conn., but four years ago it faced many of the same problems as inner-city schools in nearby Hartford: low scores on standardized tests and dropping enrollment(入學(xué)注冊(cè)). Then the school’s hard-driving headmaster, Delores Bolton, persuaded her board to shake up the place by buying a laptop computer for each student and teacher to use, in school and at home. What’s more, the board provided wireless Internet access at school. Total cost: $2.5 million.
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!”
小題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
小題2:According to the writer, students in New York City’s public schools will ______.
A.enjoy e-mail service in the near future
B.make money by selling ads on websites
C.a(chǎn)ll have their own laptops within nine years
D.become more interested in their studies with laptops
小題3:The underlined word “kinks” in the last paragraph most probably means ______.
A.plansB.projectsC.problemsD.products
小題4:From the passage we learn that ______.
A.a(chǎn) 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

Parents should stop blaming themselves because there’s not a lot they can do about it. I mean the teenager problem. Whatever you do or however you choose to deal with it, at certain times a wonderful, reasonable and helpful child will turn into a terrible animal.
I’ve seen friends deal with it in all kinds of different ways. One strict mother insisted that her son, right from a child, should stand up whenever anyone entered the room, open doors and shake hands like a gentleman. I saw him last week when I called round. Sprawling himself on the sofa in full length, he made no attempt to turn off the loud TV he was watching as I walked in, and his greeting was no more than a quick glance at me. His mother was ashamed. “I don’t know what to do with him these days,” she said. “He’s forgotten all the manners we taught him.” He hasn’t forgotten them. He’s just decided that he’s not going to use them. She confessed(坦白) that she would like to come up behind him and throw him down from the sofa onto the floor.
Another good friend of mine let her two daughters climb all over the furniture, reach across the table, stare at me and say, “I don’t like your dress; it’s ugly.” One of the daughters has recently been driven out of school. The other has left home.
“Where did we go wrong?” her parents are now very sad. Probably nowhere much. At least, no more than the rest of that unfortunate race, parents.
小題1: This text is most probably written by ______.
A.A specialist in teenager studies.
B.a(chǎn) headmaster of a middle school
C.a(chǎn) parent with teenage children
D.a(chǎn) doctor for mental health problems
小題2:The underlined word “it” in the second paragraph refers to ______.
A.the change from good to bad that’s seen in a child
B.the way that parents often blame themselves
C.the opinion that a child has of his parents
D.the advice that parents want their children to follow
小題3:The boy on the sofa would most probably be described as ______.
A.lazyB.quietC.unusualD.rude
小題4:From the second example we can infer that the parents of the two daughters ______.
A.pay no attention to them
B.a(chǎn)re too busy to look after them
C.have come to hate them
D.feel helpless to do much about them
小題5:What is the author’s opinion about the sudden change in teenage children?
A.Parents have no choice but to try to accept it.
B.Parents should pay still more attention to the change.
C.Parents should work more closely with school teachers.
D.Parents are a fault for the change in their children.

American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.
First of all, they sound very different. Often, Americans don’t say each word separately. They say several words together. Americans may say “I dunno” instead of “I don’t know”. Or they may say “Whaddya say?” instead of “What did you say?” however, the British are more careful in their speech. They usually say all the words and keep them separate.
Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary(詞匯)for cars and driving is very different. Americans drive trucks, but in England people drive lorries.
Many expressions are also different in the two countries. In England, if you are going to telephone your friends, you “phone them up”. In America, you “give them a call”.
There’re also some differences in grammar. For example, when Americans ask a question., they say “Do you have a storybook?” But the British often say “Have you a storybook?”
All these differences can be confusing (易混淆的)if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French but their French is very different from the French of France.
小題1:What does the word “separate” mean in the passage? It means “____”
A.含糊的B.快速的C.分開(kāi)的D.簡(jiǎn)略的
小題2:The vocabulary for cars and driving is _____.
A.a(chǎn)n example of British English
B.a(chǎn)n example of American English
C.the same in America and England
D.not the same in America and England
小題3:Language _________.
A.a(chǎn)re always changing as time passes
B.keep unchanged even if time changes
C.a(chǎn)re the same in all places
D.a(chǎn)re easy to learn

A.English vocabulary
B.how American sounds are different from British sounds
C.the way the British say words
D.some differences between American and British English
