(A)

Wind-even the slightest of winds can prevent frost (霜冻).That’s because wind is like a spoon in your cup of tea: it stirs (搅起)things down and brings down a lot of warm air that often floats just above housetops and trees .

It may seem strange , but ice itself sometimes can protect crops from frost . Some growers actually spray their crops with water on a freezing night . Water freezes quickly on plants and then a strange thing happens . As long as ice stays wet , it can’t get colder than 32°F, a temperaure many plants can stand . By continual spraying water on the ice , the growers keep it from going below 32 degrees even if the air is　 much colder . This may defeat frost and saves plants .

This strange kind of “ice blanket” works only on plants that are strong enough to stand the weight of frozen spray . This is used even to protect banana plants on some Central American farms .

It is the Holy Grail(长期追求的目标) of politicians everywhere-how to win and keep the trust of voters.

Now researchers at the University of St Andrew's in Scotland say they-may have the answer. They believe politicians could learn a lot from recent advances in science. A growing number of studies have shown that people do judge a book by its coven Researchers say most of us make quick judgments about a person on the basis of how they look.

Studies suggest that people are less likely to trust those with particularly masculine (男性的) features, such as a square jaw, small eyes or a big nose. "They are considered dominant (支配的)　 and less trustworthy," says Ms Cornwell "It doesn't mean that men who look more masculine are less trustworthy --it's just our first impression." Those with less masculine features--larger eyes, a smaller nose and thinner lips--- are thought to be more trustworthy.

The researchers are putting their science to the test at the Royal Society's annual summer exhibition in London. They nave manipulated (复制) the faces of Prime Minister Tony Blair, Conservative leader Michael Howard and Liberal Democrat leader Charles Kenney accentuating (强调) their dominant and trustworthy features. "We have used a computer program to change the shape of their faces and features. We hope it will help people to understand our work."

So should we expect to see them at the exhibition getting tips?

"I don't think it's something they will want to try," says Ms Cornwell. "It's not really possible with television. We all know what they look like."
