Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, 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. Just this week, a study reported that lifeexpectancy 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 fatness, smoking and high blood pressure. They also blame differences in health services around the country.
In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson , a health expert says 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 athletes in class.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward 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.

How Room Designs Affect Our Work and Feelings   ks5u

Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical（经验的，实证的） basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.   ks5u

Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.   ks5u

In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.   ks5u

Using nature to improve focus of attention ought to pay off  academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.   ks5u

Recent study on room lighting design suggests than dim（暗淡的） light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.   ks5u

So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw（吸管）," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."   ks5u

Between ten and midnight the United States is politically leaderless—there is no center of information anywhere in the nation except in the New York headquarters of the great broadcasting companies and two wire services. No candidate and no party can afford the investment on election night to match the news-gathering resources of the mass media; and so as every citizen sits in his home watching his TV set or listening to his radio, he is the equal of any other in knowledge. There is nothing that can be done in these hours, for no one can longer direct the great strike for America’s power; the polls have closed. Good or bad, whatever the decision, America will accept the decision—and cut down any man who goes against it, even though for millions the decision runs contrary to their own votes. The general vote is an expression of national will, the only substitute for violence and blood. Its decision is to be defended as one defends civilization itself.

There is nothing like this American expression of will in England or France, India or Russia. Only one other major nation in modern history has tried to elect its leader directly by mass, free, popular vote. This was the Weiman Republic of Germany, which modeled its unitary vote for national leaders on the American practice. Out of its experiment with the system it got Hitler. Americans have had Lincoln, Wilson and two Roosevelts. Nothing can be done when the voting returns are flooding in; the White House and its power will move to one or another of the two candidates, and all will know about it in the morning. But for these hours history stops.

Between ten P.M. and midnight the United States is politically leaderless because ________.

A. the president has been murdered          

B. the general strike for power has ended

C. the government has resigned             

D. the general vote is being held

“The great strike for America’s power” in Paragraph 1 refers to ________.

A. the strike of the government members

B. the great vote

C. the election campaign

D. the strike of the government employees

The author believes that the decision at the polls will ________.

A. lead to a civil war             B. result in a general strike

C. cause violence and blood     D. be defended by all Americans

Without the general vote, the author implies ________.

A. there would be a civil war    B. there would be a general strike

C. there would be an election campaign    D. there would be a fierce debate

A new study warns that about thirty percent of the world’S people may not have enough  water by the year 2025．
A private American organization called Population Action International did the new  study．It says more than 335 million people lack enough water now．The people live in 28  countries．Most of the countries are in Africa or the Middle East．
P—A—I researcher Robert Engelman says by the year 2025，about 3，000 million people may lack water．At least 18 more countries are expected to have severe water problems．The
demand for water keeps increasing．Yet the amount of water on Earth stays the same．
Mr．Engelman says the population in countries that lack water is growing faster than ini other parts of the world．He says population growth in these countries will continue to increase．
The  report says lack of water in the future may result in several problems．It may increase health problems．Lack of water often means drinking waters not safe．Mr．Engelman says there are problems all over the world because of diseases，such as cholera。
which are carried in water．Lack of water may also result in more international conflict．Countries may have to compete for water in the future．Some countries now get sixty percent of their fresh water from other countries．This is true of Egypt，the Netherlands，Cambodia，Syria，Sudan，and Iraq．And the report says lack of water would affect the ability of developing to improve their economies．This is because new industries often need a large amount of water when they are beginning．
The Population Action International study gives several solutions to the water problem．One way，it says，is to find ways to use water for more than one purpose．Another way is to teach people to be careful not to waste water．A third way is to use less water of agriculture．
The report also says long--term solutions to the water problem must include controls on population growth．It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have．
1．The first four paragraphs mainly tell us__________
A．the fact of the global lack of water
