A

The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercises or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧运动), strength building, and flexibility (柔韧) exercise. Make exercise a habit by arranging some time every day.

On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.

Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.

Here are five simple ways to make an exercise lifestyle change:

1) Start today. Go outside for a walk.

2) Take the stairs instead of the elevator (电梯).

3) Instead of driving, walk or bike to places like school or a friend’s house.

4) Clean your room or wash your car. It’s an exercise opportunity!

5) Limit your time watching TV, using the computer, or playing video games. When you do play, try the games that get you moving.

56. The author thinks many people probably misunderstand the word “activity” to be “_______”.

A. physical activity      B. body movement  C. sports hall exercise        D. outdoor exercise

57. When exercising, the most important factor is ________.

A. the time spent on exercise     B. the intensity of activity

C. the difficulty of exercise      D. the right balance of activity

58. The author advises dividing activity into shorter exercise breaks because ________.

A. exercising for a long time is bad for people’s health

B. it has the same effect as soccer practice

C. people usually haven’t much time to exercise

D. no one can spare lots of time to exercise

59. What’s the best title for this passage?

A. Regular exercise.        B. School exercise.   C. Indoor exercise.         D. Difficult exercise.

B

Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and poor countries, choice is a luxury(奢侈), something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers hoping to sell their products.

The endless choice gives birth to anxiety(焦虑) in people’s lives. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range(范围) of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item(商品) that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors.

It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing; no choice, no anxiety.

60.What does the author try to argue in Paragraph 1?

A. The exercise of rights is a luxury.          B. The practice of choice is difficult.

C. The right of choice is given but at a price.   D. Choice and right live at the same time.

61.Why do more choices of goods give rise to anxiety?

A. Professionals find it hard to decide on a suitable product.

B. People are likely to find themselves overcome by business persuasion.

C. Shoppers may find themselves lost in the broad range of items.

D. Companies and advertisers are often misleading about the range of choice.

62.By using computers as an example, the author wants to prove that _________.        .

A. advanced products meet the needs of people B. products of the latest design flood the market

C. competitions are fierce in high-tech industry D. everyday goods need to be replaced often

63.What is this passage mainly about?

A. The variety of choices in modern society.

B. The opinions on people’s right in different countries.

C. The problems about the availability of everyday goods.

D. The helplessness in purchasing decisions.

We recently read a report on China’s environmental problems, based on reports from Singapore’s Straits Times. There was one statistic that shocked us. Environmental experts claim that without some great change, pollution might, within five years, make the Yangtze River just about unsuitable for all forms of life to live in. The baiji, or the Yangtze River dolphin, was only the latest victim. According to the first report, in the 1980s there were 126 forms of life in the river, and by 2002, that figure was already down to 52.

Just how bad is the situation? The Yangtze River flows by 186 cities on its way from Qinghai to Shanghai, and in the process picks up 40% of China’s polluted waste water. According to another report, in 2006, China produced a total of 53.7 billion tons of waste water. But that’s not the worst news. By 2030, China might possibly use up between 89-100% of its sources of drinking water.

All of this begs a deeper question: What kind of water are they using when they pump 10 kilos of water into pigs headed for the slaughterhouse(屠宰场)? This is an important question because if its waste water is not fit for human to drink, there’s a chance that some of whatever was in that water was in the pork you had for lunch today. And if the water is safe to drink, that’s a waste of perfectly good water.

Another report we read, related to the Taihu algae(水藻) blooming that has left 3 million people in the Wuxi area without drinking water, claims(quite believably) that Taihu’s environmental problems will never end until all the factories along the lake close down. The algae bloom is so bad there that lots of people have to take the algae out of the lake all day long instead of fishing.

64.From the first paragraph we learn that__________.

A. this passage is taken from Singapore’s Straits Times

B. over 70 species of life disappeared from the Yangtze River in about 20 years

C. there were only 52Yangtze River dolphins left in the river in 2002

D. you will see no life in the Yangtze River in the coming five years or so

65. Which of the following statements is NOT true about the Yangtze River according to the passage?

A. It goes by 186 cities on its way from the source to the sea.

B. Lots of waste water in the country is poured into the river.

C. The baiji in the river is now in danger of extinction.

D. We can hardly see any forms of life in the river now.

66. Which of the following problems is the most urgent according to the passage?

A. There is no clean water to pump into pigs which are to be slaughtered.

B. A large amount of waste water is produced every year in China.

C. The sources of drinking water might be almost used up in the future.

D. There are poisonous things in the pork that people eat.

67. It can be concluded from the last paragraph that___________.

A. the factories along the lake have contributed to the pollution

B. fishermen have taken up the job of cleaning the lake.

C. all the factories in Wuxi have been shut down to protect the lake.

D. many people are sent to the lake to help protect the algae.

Among the seven wonders of the ancient architectural (建筑方面的) world, the pyramids in Egypt are the only ones still standing.

For 1,000 years, they were the tallest buildings in the world. Built with prehistoric technology, they were an architectural mystery, as strange as the Sphinx (狮身人面像).

No one really knows how they were built. The first historical record, by the Greek writer Heroditus, came 2,000 years later. Without hard facts, there have been many theories.

Hollywood has mostly followed the examples from the Greek record: 100,000 slaves worked hard for 20 years. Others believe a very large slope snaked around the pyramids. An American recently put forward the theory that kites could have lifted the 2-ton stones.

Now Houdin, a French architect, says that after studying the pyramids for eight years, he has solved the mystery with the help of 3-D computer animation (三维动画). He believes the pyramids were built from the inside out through an internal slope that goes around a central point. “This is completely new. Everyone before me thought that the pyramids were built from the outside, and only from the outside,” he said.

Scholars of ancient Egypt are interested. “It’s a theory which sounds reasonable. Scholars of ancient Egypt agree it ought to be tested, and it doesn’t cause damage, so I wouldn’t be surprised that within a year, we have the final answer,” said Bob Brier, a scholar at Long Island University.

If that is the case, we’ll know the truth about the pyramids in the blink of an eye, considering this mystery has lasted for nearly 5,000 years.

68. There are many theories of how the pyramids were built because ________.

A. researchers have different professional knowledge

B. researchers research the pyramids from different aspects

C. there are no reliable records of how the pyramids were built

D. there are many stories about how pyramids were built

69. The French architect Houdin put forward his theory with the help of ________.

A. many experts       B. computer technology   C. some scholars of ancient Egypt     D. the historical record

70. The underlined phrase “in the blink of an eye” in the last paragraph probably means “______”.

A. in a short time     B. in the distant future   C. only by using your own eyes     D. in the state of uncertainty
