The reasons for a person’s becoming an alcoholic have often been debated by psychologists and other scientists. But recent studies suggest that the problem of alcoholism(酒精中毒) should also be the focus of investigation by biologists.

While such things as hard jobs, boredom, and unhappiness can lead to alcoholism, researchers at a prominent university have found that there may also be a genetic factor involved in alcoholism. In the study, children of alcoholic parents were surveyed. The result showed that the children of alcoholic parents were more likely to become alcoholics themselves than were children of non-drinking parents.

This evidence in itself is not conclusive（令人確信的）about anything. After all, it may be the constant exposure（接觸）and easy access to alcohol that cause the children of alcoholics to become alcoholics themselves. But there is more evidence. The study found that children born of alcoholic parents but raised by non-drinking foster（撫養(yǎng)的）parents also were susceptible to alcoholism. This group of offspring（后代）was more likely to take up drinking than youngsters who were born of and raised by non-drinking parents.

Other evidence found in the study suggests that environment does not play as important a role in the development of alcoholism as had been previously thought. The study found that the likelihood of alcoholism was better predicted from the characteristics of the parents than from such environmental characteristics as type of job or level of income.

Iceland has the highest birth rate in Europe, the highest divorce rate, and the highest percentage of women working outside the home. Such statistics are often evidence of a miserable, chaotic（混亂的）society, with loads of children, broken homes and absent mothers. But Iceland is the exception – its citizens are the happiest in the world.

Perhaps the country's geographic location contributes to Icelanders' happiness. Located in the middle of the North Atlantic, with Greenland as its nearest neighbor, Iceland is free from the taboos（禁忌）that cause so much trouble elsewhere. For instance, people who divorce are not looked down upon by society.

Icelanders are offsprings（后代）of the Vikings, a north European people who invaded European coasts from the 8th through the 10th century. This tradition of getting out into the world lives on in modern-day Iceland. Practically all Icelanders have studied or worked abroad, and most speak English.

Perhaps as a result, Iceland's economic policies blend the best of those from Europe with the US to create its own welfare system.

"Many of us have lived in the US, and studied there," said the Icelandic Prime Minister Geir Haarde. "We have both taken from them and found that naturally we share the can-do attitude—— that if you work hard, anything can be done."

Indeed, the country is rich in writers, painters, film makers and musicians. There's Sigur Ros, a post-rock band, and also a national symphony orchestra that plays to the highest standards all over the world. Half the population appears to have written a book.

"Iceland has harsh（惡劣的） nature, with its bitter ever-changing weather,” said Haraldur Jonsson, a painter, sculptor and video and performance artist. “We cannot escape it. So we find ways________. We have to have a rich internal（內(nèi)在的）life to fill the empty spaces."

57．It is commonly believed that high birth rate and divorce rate will bring about ________.

       A．social problems              B．happiness

       C．a(chǎn) unique welfare system     D．modern way of life

58．The underlined word "blend" in the fourth paragraph means            .

       A．combine       B．correct          C．compare       D．compete

59．Which of the following is NOT mentioned as the reason for Icelanders’ happiness?

       A．Geographic location.       B．A rich internal life.

       C．National pride.     D．Freedom from taboos.

60．The most suitable phrase to fill in the blank in the last paragraph is             .

       A．to get rid of it    B．to have it changed  C．to get away from it        D．to live with it
