1、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital (婚外的) affairs will be even more common than now.But what are the reasons for this, and is the picture really so gloomy (明暗的)? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands－as they usually didn\'t have jobs outside the home. But with the rising number of women in well－paying jobs, this is no longer the case, So they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic (悲观的) as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Why is the outlook of marriage not as hopeless as it appears? ____【单选题】

A. Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 60% of the marriages continue to exist.

D.The statistics of divorce is reliable.

正确答案:A

答案解析:本题难度也不大，正确答案正好是选项A，所以看到A的信息提示，然后马上回到原文验证，可以找到答案依据是文章第三段第二句后半部分：…so marriage is still quite popular.

A.in despair

B.in danger

C.in misery

D.in pain

正确答案:B

4、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. Others will die out for lack of food. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. This allowed scientists to gauge the pace and progress of the ecological recovery. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. ______.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:B

答案解析:选项B中的关键词other businesses、farming、property提示，选项B的句子是前面句子的后续句，因为前面句子有mining、tree harvesting，也是businesses。蚂蚁分析法已被 mining和tree harvesting等行业广泛接受，但在farming和property行业中的应用还不普遍。
