科目:高中英語 來源:2013屆福建省高二12月月考英語試卷(解析版) 題型:閱讀理解

You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But did you know there is a “banana person”? How strange! Are these people from “another Earth”? No. They are just Chinese people like you and me.

ABC means American-Born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside—thinking like a Westerner and yellow outside—looking like a Chinese.

Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don’t speak Chinese.

But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas  Chinese. These people may be citizens of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair.

But they are not Chinese citizens. They are not the people of the People’s Republic of China. For example, we all know the famous scientist  C.N. Yang(楊振寧). He got the Nobel Prize for Physics in 1957. The Chinese love him, but he is an American citizen.

1.What’s the author’s purpose in writing this passage?

A.He wants to tell us something about “ABC”.

B.He wants to show that Chinese are well respected in America.

C.He wants to tell us some knowledge about the English language.

D.He wants to introduce the American culture to us.

2.Chinese in Western countries are called “banana persons” because ____.

A.their bodies are white inside but yellow outside

B.they think like Westerners but look like Chinese

C.they were born in China but go to study in America

D.they like to eat bananas

3.C.N. Yang is mentioned here to show that ____.

A. American Chinese are great      

B. we love American Chinese

C. The Chinese can win Nobel Prizes

D. American Chinese are not Chinese citizens

4.Which is NOT true?

A. ABCs are Chinese people.

B. ABCs are all “banana persons”.

C. If you go to America or another country one day, you’ll really become an ABC.

D. ABCs know our country very little.

5.What does the underlined word in the passage mean?

A.People who born and live or work in other countries.

B.People who love other countries.

C.People who know other countries very much.

D.People who can speak other countries’languages.

If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.

“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.

Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.

Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.

When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.

Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.

Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.

1.From the passage we know that it is good for our health to ____ .

A.eat a lot

B.go to bed early

C.get up late

D.go to bed late

2.How long should young boys and girls need to sleep a day?

A.More than ten hours

B.Over eleven hours.

C.Less than seven hours.

D.Eight hours or so.

3.If we want to keep healthy, we must ____ .

A.eat more food

B.sleep more

C.get up late

D.take enough exercise

4.Which of the following habits is NOT GOOD?

A.Don’t go to bed until twelve o’clock..

B.Take a walk after supper.

C.Run in the open air early in the morning.

D.Climb hills for half an hour early in the morning.

科目:高中英語 來源:2013屆江蘇省宿遷市四校高二下學期5月聯考英語試卷(解析版) 題型:閱讀理解

Do you know soon eleven biggest food and drink companies of the nations will adopt new rules to limit advertising to children under the age of 12, a move that restricts ads for products such as McDonald’s Happy Meals and the use of popular cartoon characters.

The companies announced their new rules ahead of a Federal Trade Commission hearing on Wednesday that steps up pressure on the companies to help solve the growing child obesity problem through more responsible marketing. The self-given rules include promises by seven companies who will no longer use licensed characters, such as those made popular through movies or TV shows, to advertise online or in print media unless they’re promoting their healthier products. Four other companies said they do not advertise at all to children under 12.

“I think this is a very good step forward. It’s not the end of the journey but it’s a good way down the road,” said Margo Wootan, Nutrition Policy Director at the nonprofit Center for Science in the Public Interest.

Since the FTC first publicly raised the issue in 2005, many of the companies have started selling products with better nutrition in mind. The companies hope their self-regulation efforts — organized through the Council of Better Business Bureaus — will fend off any new and more strict federal regulation.

Parents are happy to see new rules that restrict the use of cartoon characters such as Shrek, Dora the Explorer and SpongeBob SquarePants. “It catches their eyes when you’re shopping,” said Josephine Thomas, a mother of three boys who lives in Manhattan. “As soon as they see a Shrek or Mickey Mouse, they automatically look at that and they don’t see what they really need. That’s one of the biggest problems when you go shopping.” That’s one reason the food companies have said they will now only use licensed characters to advertise their “better for you” products.

1.The reason why the food and drink companies will take action is that they want to___________

A.promote sales across the country

B.limit advertising to children under the age of 12

C.meet increasing demands from kids

D.adapt to the new federal regulations

2.What can we learn from the text that the seven companies ____.

A.may still use cartoon characters in advertising

B.are going to stop advertising to children under 12

C.Would like to continue the cooperation with entertainment media

D.will make food and drink specially for fat kids

3.What of the following can best describe the underlined words “fend off”?

A.prevent ... from happening

B.draw up or work out

C.pay attention to

D.give a warm welcome to

4.What does Josephine Thomas advise in the last paragraph?

A.kids spend too much on unhealthy food

B.parents are strict about their kids’ food choice

C.“better for you” products are popular with kids

D.ads with cartoon characters mislead kids
