　　Choosing an Occupation

　　One of the most important problems a young person faces is deciding what to do. There are some people, of course, who from the time are six years old “know” that they want to be doctors or pilots or fire fighters, but the majority of us do not get around to making a decision about an occupation or career until somebody or something forces us to face the problem。

　　Choosing an occupation takes time, and there are a lot of things you have to think about as you try to decide what you would like to do. You may find that you will have to take special courses to qualify for a particular kind of work, or you may find out that you will need to get actual work experience to gain enough knowledge to qualify for a particular job。

　　Fortunately, there are a lot of people you can turn to for advice and help in making your decision. At most schools, there are teachers who are professionally qualified to give you detailed information about job qualifications. And you can talk over your ideas with family members and friends who are always ready to listen and to offer suggestions。

　　Part II Reading Comprehension (Skimming and Scanning)

　　1.【解析】[Y]該句的意思是巨大的河流改道水利工程使得咸海縮小。從第二段的中間兩句話可得出結(jié)論。Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate(provide water for)farmland. As a result, the sea has shrunk to half its original size, stranding ships on dry land。與原文意思相同。

　　2.【解析】[N]該句句意為：巨壩和灌溉工程的建設(shè)好處多于壞處。解題依據(jù)為本文第三段第二句話But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. (雖然產(chǎn)生更多問(wèn)題，許多國(guó)家仍繼續(xù)建巨壩和灌溉工程。)由此可知，壞處多于好處，所以該題與原文之意不符合。

　　3.【解析】[Y]該句句意為：缺水的主要原因是人口增長(zhǎng)和水污染。本題解題依據(jù)可定位到本文第四段第一句話 Growing populations will worsen problems with water... 及第十一段第一句話But almost everyone contributes to water pollution. 兩者都是水資源缺乏的原因，與原文之意相符。

　　4.【解析】[Y]該句句意為：美國(guó)人面臨的有關(guān)水的問(wèn)題為地下水的減少和污染。本題解題依據(jù)為第七段第二句話和第八段第三句話，這兩句話加在一起即為美國(guó)人所面臨的水資源方面的問(wèn)題，與原文之意相符。

　　5.【解析】[N]該句句意為：根據(jù)這篇文章，所有水的污染都來(lái)自于家庭廢棄物。本題解題依據(jù)為第十一段最后一句話...70 percent of the pollutants could be traced to household waste (百分之七十的污染物源于家庭廢棄物)，據(jù)此，本題之意與原文之意不符合。

　　6.【解析】[N]該句句意為：美國(guó)人將不會(huì)面臨缺水問(wèn)題。該題解題依據(jù)為文章第七段第二句話 But Americans could face serious water shortages, too, especially in areas that rely on groundwater, 顯然本題之意與原文之意不符合。

　　7.【解析】[NG]該句句意為：水利專(zhuān)家Gleick 提供了與水相關(guān)的最佳解決方案。根據(jù)本文第十三段第一句話所述，專(zhuān)家Gleick 并未提供任何最佳解決方案。

　　8.【解析】one-third 解題依據(jù)為第四段最后一句話：He fears that by the year 2025, as many as one�瞭hird of the world’s projected 8.3 billion people will suffer from water shortages。

　　9.【解析】glaciers and ice caps 解題依據(jù)為第五段第二句話：Two-thirds of this freshwater is locked in glaciers and ice caps。

　　10.【解析】water pollution 解題依據(jù)為第十段第二句話：Toxic chemicals pollute water when released untreated into rivers and lakes。
