first, china needs to undergo rapid economic development before a population decline hits the country. second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.russia is another country with population problems that could break its economic promise. since 1992 the number of people dying has been bigger than that of those being born by a massive 50%.indeed official figures suggest the country has shrunk by 5% since 1993 and people in russia live a shorter life now than those in 1961. why is this occurring?nobody is quite sure, but poor diet and above all long-time alcoholism have much to do with it. if current trends dont bend, russias population will be about the size of yemens by the year 2050.in the north of india, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. in a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. in total, 25% of indias working-age population has no education. in 2030, a sixth of the countrys potential work force could be totally uneducated.one solution is obviously to import foreign workers via immigration. as for the usa, it is almost unique among developed nations in having a population that is expected to grow by 20% from 20102030. moreover, the usa has a track record of successfully accepting immigrants. as a result its likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.参考答案单项选择1.a句意:警察决定对这个案子进行一次彻底的、全面的审查。本题考查形容词词义辨析。要填的形容词应该和thorough(彻底的)是并列的,故选comprehensive(全面的)。complicated复杂的;conscious有意识的,清醒的;crucial至关重要的。2.b句意:你t恤上的东西是什么意思啊?没什么,只是随便写上去的而已。本题考查习语。根据题干中的nothing可知没有特别含义,因此选择b项,off the top of ones head“不假思索,即兴”。3.c句意:你知道吗?我得到了一张新年音乐会的门票。哦,算了吧。你在开玩笑。考查情景交际。come on在此处意为“算了吧;得了吧”。so what?那又怎样?go ahead.可以。what for?为什么?4.d句意:仅仅在史蒂夫乔布斯去世5年后,智能手机在销量上就打败了传统的个人电脑。本题考查形容词辨析。根据句意可知此题应选择d项,conventional“传统的”。controversial“有争议的”,contradictory“自相矛盾的”,confidential“机密的”。5.a句意:他的全面的调查就数据收集的方式和依据做出了清楚的描述。考查形容词辨析。explicit易于理解的,清楚的;ambiguous不明确的;original原先的,最初的;arbitrary武断的。6.d句意:通过对比我们周围的环境来确定我们的位置仍然是我们生存的重要技能。本题考查介词短语辨析。根据句意可知,应选择in relation to“相对于而言”。in contrast to“和相比”,in defense of“为辩护”,in(the) face of“面临”。7.b句意:无人驾驶是一个中国和世界其他国家处在同一起跑线上的领域。考查定语从句。设空处引导的是定语从句,修饰先行词an area。将先行词代入定语从句后为:china and the rest of the world are on the same starting line in the area. 由此可知,关系词在定语从句中作地点状语,所以要用关系副词where引导。8.b句意:在非洲医疗队的工作让她作为医生的才能得到了最大限度发挥。本题考查动词短语辨析。根据句意可知,应选b。bring out意为“使显现,使表现出”,常构成bring out the best in sb.这一表达。9.b句意:尽管这家宾馆的服务质量很糟糕,但是宾馆经理还是不愿意在给员工足够的培训方面投资。考查形容词。reluctant 勉强的,不愿意的,符合语境。keen 热切的;着迷的。anxious 焦急的;焦虑不安的。ready 准备好的;愿意的。10.a句意:在年底对一年的成功和失败进行一个快速的回顾会有助于你下一年的发展。本题考查动词词义辨析。shape影响的发展;switch改变,转换;stretch伸展;sharpen加剧,使尖锐。a项符合题意。故选a项。任务型阅读语篇解读本文为说明文,题材是社会科学类。作者论述了世界人口增长的原因以及低出生率对国家经济的影响。1.lower根据第一段最后一句以及第二段第一句可知,21世纪的出生率低于(lower than)20世纪。2.size/scale根据第二段第二句中的and almost all developed nations are experiencing sub-replacement birth rate可知,几乎所有的发达国家都面临人口出生率低的问题。故此处指发达国家很难维持人口规模(the size/scale of population)。3.immediate根据第二段最后一句可知,在许多发展中国家,出生率下降是一个主要问题,这可能在几十年内造成全球灾难性的劳动力短缺问题。故此处指发展中国家出生率下降影响可能不是立即就能表现出来的,但却是灾难性的。关键信息:within a few decades。4.economic文章从第三段开始,举例分析了发展中国家出生率与经济发展的关系。故此处副标题应为“人口与经济压力”。5.old/older根
