17、的农业得到改造，工业也用上了水坝发的电。C、过去不断给农民带来灾难的旱涝两灾，现在不再发生了。埃及的农业得到了改良，水坝发的电也用在了工业上。D、过去不断给农民带来灾难的不但有旱涝两灾，还有税收。但是埃及的农业得到了改良，工业也给水坝发电带来了很大的好处。【正确答案】A【答案解析】答案选A。句子中tax of suffering属于比喻，把suffering比作是强加在人们身上的tax,而并非真正的征收税收。根据这一点可以排除B 和 D 项，同时根据句子中的and可以得知前后应该是并列的，也就是说agriculture和 industry是并列的，同时翻译的时候也应该是并列的，这样不但符合句法

36、evenues,and thus encourage bankers to take irresponsiblerisks.【正确答案】由于国家金融体系正濒临崩溃，一些大银行和金融机构高管人员的薪酬协议将再次受到严密的审查。银行家们过于冒险的行为是导致此次金融危机的一个重要原因，也是历史上其他金融危机产生的原因之一。而这次的危机由低利率引起，并在债务泡沫经济带来的虚假安全感下持续恶化。抵押贷款人很乐意把大量资金借给无偿还能力的人。他们拆分贷款并沿着这一链条把其出售给下一家金融机构。该机构利用同样的高技术证券化方式运作更大风险的抵押资产。金融监管将不得不与时俱进来应对造成银行以这种方式破产的极不

44、现的量。第34题【单选题】think the teacher is wr o n g,?”No,I dont think so.A、dont youB、dont IC、doesnt heD、doesn/t she【正确答案】A【答案解析】答案选A。此题容易误选C或D,因为按照语法规则，I think后接宾语从句时，其反意疑问句与从句保持一致，但是退一步，即使按此规则，其反意疑问句也应是isMthe或isnt she之类的，而不是像C或D那样用doesnt he和doesn,t she。综合四个选项,最佳答案为A,don/t you为dontyou think so 之省略。第35题【单选题】M

48、 first time in my life,regretful I was about the time wasted playing around.A、where,thatB、that,howC、that,whichD、where,how【正确答案】B【答案解析】答 案 选 B o 该句是一个强调句，其中还有一个插入语for the first time in my life ,强调句的基本形式是“It is(was).that(who)./先行词是人时可用who代替th a t,否则一般用th a t,故排除A、D o 又因为regretful是一个形容词，故应用副词修饰，显然要舍去wh
49、ich而 用 how。第37题【单选题】The country was a place where men worked from dawn to dark,and thelabourer lived not in the sun,but in poverty and darkness.A、在农村，人们从早到晚都得干活,劳动者并不是沐浴在阳光下，而是生活在贫困和黑暗之中。B、在农村，人们从早到晚都得干活，劳动者不是沐浴在阳光下,而是贫困和黑暗。C、在这个国家，人们从早到晚都得干活，劳动者不是生活在阳光下，而是挣扎在贫穷和黑暗之中。D、在这个国家，人们从早到晚都得干活，劳动者不是沐浴在阳光下，而
