[单项选择]Researchers investigating brain size and mental ability say their work offers evidence that education protects the mind from the brain’s physical deterioration.
It is known that the brain shrinks as the body ages, but the effects on mental ability are different from person to person. Interestingly, in a study of elderly men and women, those who had more education actually had more brain shrinkage.
"That may seem like bad news," said study author Dr. Edward Coffey, a professor of psychiatry and of neurology at Henry Ford Health System in Detroit. However, he explained, the finding suggests that education allows people to withstand more brain-tissue loss before their mental functioning begins to break down..
The study, published in the July issue of Neurology, is the first to provide biological evidence to support a concept called the "reserve" hypothesis, according to the researchers. In recent years, investigators have developed the idea that people who are more ed

[单项选择]
M: Hi, Claire. How does it feel to be back on campus

M: I can see it was hard to leave that job. But how did you teach a bird how to eat and drink

Paying for Nature
A. How much are the birds of heaven worth How about the lilies of the field Or clean air and water, verdant forests and untouched grassland, healthy coral reefs and lush mangroves By the environmentalist’s accounting, they’re invaluable because nature has a worth all its own. But to business, untouched nature typically hasn’t had a value—at least not one that could be put in a
ledger(账簿).
B. Until now, many green—and a growing chorus of corporate suits—are arguing that nature in its own right provides economically valuable services that benefit business. A virgin forest is pleasant to look at, of course, but it also prevents soil erosion and improves water quality at no cost—valuable if you happen to own a
beverage (饮料) plant downstream that depends on clean water. That same forest might provide a habitat for bees, which can
pollinate(授粉) plants in the surrounding cropland—a vital f

One-room Schools
One-room schools are part of the heritage of the United States, and the
mention of them makes people feel a vague longing for "the way things were".
One-room schools are an endangered species (濒于灭绝的物种), however. For more than a
hundred years, one-room schools have been systematically (系统地) shut down (关闭)
and their students away to centralized schools. As recently as 1930 there were
149, 000 one-room schools in the United States. By 1970 there were 1, 800.
Today, of the nearly 800 remaining one-room schools, more than 350 are in
Nebraska. The rest are scattered through a few other states that have on their
road maps wide-open spaces between towns. Now that there are
hardly any left, educators are beginning to think that A. Some children have to be left back. B. Teachers are always busy. C. Pupils have more freedom. D. Learning is not limited to one grade level at a time.
