Research shows that it takes from 10 to 20 repetitions of a word to really make it a part of your vocabulary. It helps to write down the word—both the definition and a sentence using it—perhaps on an index card, where it can be easily reviewed.

On the one side is the West( plus Japan). with banks that are over-utilized and thus dysfunctional(不能正常动作的), governments groaning under debt, and consumers who are rebuilding their broken balance sheets. America is having trouble selling its IOUs at attractive prices( the last three Treasury auctions (拍卖) have gone badly) ; its largest state, California, is heading toward total fiscal collapse; and its budget deficit is going to surpass 13 percent of GDP—a level last seen during World War II. With all these burdens, even if there is a recovery, the United States might not return to fast - paced growth for a while. And it's probably more dynamic than Europe or Japan. All the following are problems the West is facing EXCEPT thatA. banks are not functioning properly.B. governments are buried in too much debt.C. people have big financial problems.D. economy is experiencing quick recovery.

单选题They Say Ireland"s the Best Ireland is the best place in the world to live in for 2005, according to a life quality ranking that appeared in Britain"s Economist magazine last week. The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being. The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life". Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality and the high cost of living, Ireland scored an impressive 8.33 points out of 10. That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe. troubled by political insecurity and hunger, is rated the gloomiest (最差的), picking up only 3.89 points. "Although rising incomes and increased individual choices are highly valued," the report said, "some of the factors associated with modernization such as the breakdown (崩溃) in traditional institutions and family values in part take away from a positive impact." "Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life." The magazine admitted measuring quality of life is not a straightforward thing to do, and that its findings would have their critics. No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain. The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP (人均国内生产总值) after Luxembourg, took the 13th place in the survey. China was in the lower half of the league at 60th.

However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health. From this researchers have concluded that the day-to-day factors that cause stress are not random. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 per cent of the study days, people with a high school degree reported stress 38 per cent of the time, and people with college degrees reported stress 44 per cent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health." lead researcher Dr. Joseph Grzywacz, of Wake Forest University Baptist Medical Center, said in a prepared statement. "The downward turns in health were connected with daily stressors. And the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic. "If something happens every day, maybe it's not seen as a stressor," Grzywacz says. "Maybe it is just life." stressful adj. 紧张的;压力重的 diploma n. 毕业文凭,毕业证书 stressor n. 紧张刺激物 devastating adj. 毁灭性的 follow-up n. (对病人的)随访
