题目内容

阅读下面短文,根据所给语境,按要求完成下列各题。

  It may seem strange that ice itself can sometimes protect crops from frost(霜). 1 Some growers actually spray(喷洒) their crops with water on a freezing night. Water freezes quickly on the plants and then a strange thing happens. 2 As long as ice stays wet, it can't get colder than 0℃, a temperature many plants can survive(存活) at. If the ice ever became completely frozen and dry, it might drop many degrees lower, destroying the plants. 3 By continually spraying water on the ice, the growers keep it from going below 0℃ even if the air is much colder. This may be unbelievable, but it saves the plants.

  This strange kind of ice blanket(毯子) works only on plants that are strong enough to stand the weight of frozen spray. This method is even used to protect banana plants on some Central American Plantations(种植园).

  Are people less happy or happier when they get older? If your answer is “happier”, then you are right, based on a study published five years ago. It found that people generally become happier and experience less worry after age fifty. In fact, it found that by the age of eighty-five, people are happier with their life than they were at eighteen.

    The findings came from a Gallup survey of more than three hundred and forty thousand adults in the United States in 2008. At that time, the people were between the ages of eighteen and eighty-five.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were the highest among adults between the ages of twenty-two and twenty-five. Stress levels dropped sharply after people reached their fifties.

    Levels of happiness were the highest among the kids and those in their early seventies.

The survey also found that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men did.

So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
