[简答题]A Grassroots Remedy
Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular leisure activity in Britain is going for a walk. And when joggers (慢跑者) jog, they don’t run the streets. Every one of them instinctively heads to the park or the river. It is my profound belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not.
But despite this, our children are growing up nature-deprived (丧失). I spent my boyhood climbing trees on Streatham Common, South London. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and odd new perceptions about what is best for children, that is to say, things that can be bought, rather than things that can be found.

[单项选择]
The swine flu will probably return in force earlier than seasonal flu usually begins, federal health officials predicted Friday, saying they expected it to erupt as soon as schools open rather than in October or November.
The swine flu is still circulating in the United States, especially in summer camps, even though hot weather has arrived and the regular flu season ended months ago, "so we expect challenges when people return to school, when kids are congregating together," Dr. Anne Schuchat, director of respiratory diseases at the Centers for Disease Control and Prevention, said in a telephone news conference held jointly with vaccine experts from the Food and Drug Administration and the Department of Health and Human Services.
It is still unclear how many doses of a swine flu vaccine will be available by then, and officials have been reluctant to make firm predictions beyond saying that they expect tens of millions, rather than hundreds of millions,

The Cold Places
The Arctic is a polar region. It surrounds the North Pole.
Like Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading—125 degrees Fahrenheit below zero. Reading of 85 degrees below zero is common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter average is about 73 degrees below zero.
One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic. This one thing is the low temperature-the killing chill of far North and the polar South.
To survive, men must wear the warmest possible clothing. They must build windproof shelters. They must keep heaters going at all times. Not even for a moment can they be unprotected against the below-zero temperatures.
Men have a way of providing for themselves. Polar explorers wrap themselves in warm coa
