【题目】In the US, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.

Yet many schools across the country have reduced their physical education programs. Criticism of the cuts has led in some places to efforts to give students more time for exercise, not less. The future health of Americans may depend on it. A study reports that life expectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in obesity,smoking and high blood pressure. They also blame differences in health services around the country.

In 2006, a study found that only 4% of elementary schools provided daily physical education all year for all grades. This was true of 8% of middle schools and 2% of high schools. The study also found that 22% of all schools did not require students to take any P. E. One problem for P. E. teachers is that schools are under pressure to put more time into academic subjects.

Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athlets in class.

But experts say P. E. classes have changed. They say the goal has moved away from competition to personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.

Some parents like the idea of avoiding competitive sports in P. E. class. Yet others surely dislike that idea. In the end,schools may find themselves in a no-win situation.

【题目】In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.

Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.

Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can alsohelp to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.

The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

1The traditional business model is harmful because of all the following EXCEPT that .

A. it makes the world warmer

B. it consumes natural resources

D. it makes growth hard to continue

2What can we infer from Paragraph 2?

A. China lacks wind and solar energy.

B. China is the leader of the low-carbon market.

C. High-speed trains are a low-carbon development.

D. Palm oil is made at the cost of valuable forests.

3To fully develop the low-carbon markets governments can ______.

A. cut public expenses

B. forbid carbon emissions

C. develop public resources

D. encourage energy conservation

4We can learn from the last paragraph that businesses have many chances to _______.

A. develop sustainable products

B. explore new natural resources

C. make full use of natural resources

D. deal with the major challenge

5What is the main purpose of the passage?
