Exercise Twenty-Six 1. Man，no less than the lower forms of life，_______________(是演化过程的产物). 2. _______________(不止一个人觉察到)her agitation. 3. ________________(液体密度越大)，the easier it is to float on it. 4. _______________(只有工人的要求得到满足)will they return to work. 5. Had ________________(要不是有水库)we'd never have been able to beat the drought. 1. is a product of the evolutionary process 解析：单数名词+with，together with，along with，as well as，accompanied by，no less than，rather than，in addition to，instead of，including，besides等+名词结构作主语时，谓语动词用单数。Man在这里是个单数概念，指全人类，因此句子谓语部分要用单数is。再如：A technician，along with some young workers，is working on the design.(技术员正在和一些青年工人一道搞设计。)本题全句意为：人类，同生命的低级形式一样，是演化过程的产物。 2. More than one person has noticed 解析：many a或more than one所修饰的名词作主语时，谓语动词必须用单数。所以句子需填入部分谓语译成has，又由于"觉察到"暗示了动作已经发生，因此用完成时态。但是，考生要注意的是：如果more than one后面又出现了thousand，hundred等，动词就要用复数，如：More than one thousand graduates have responded to the Party's call and gone to work in the border regions.(一千多名毕业生响应党的号召，到边疆工作去了。) 3. The denser a liquid is 解析：本题考查的是"the+adj.比较级，the+adj.比较级"的结构，表示"越......越......"。The denser在句中充当表语。当表语前置，主语和系动词用正常语序即可。当前置的表语为形容词词组、介词短语等，主语和系动词就要倒装。如：To north of the town was little village，where I spent my childhood in happiness.(在这个小城镇的北边有一个小村庄，我在那儿幸福地度过了我的童年。) 4. Only when the workers' demands are satisfied 解析：本题考查only修饰的状语放在句首，主谓要倒装。Will they return to work已经给出暗示。此外，only+副词，only+介词短语置于句首，主谓也要倒装。如：Only with the aid of telescope can he observe the celestial bodies.(只有借助望远镜，他才能观测到天体。)值得注意的是：如果句首only修饰的是主语，则不需要倒装。如：Only Tom has been to the small island once before.(只有汤姆以前去过那个小岛一次。) 5. it not been for the reservoir 解析：由于句首已经给出Had，那么这里就是考查虚拟语气省略if引起的主谓倒装。由主句时态可知，从句情况与过去事实相反，因此用过去完成时态。另外，如果句首倒装的条件句含有否定词not，且had提前，一般不可使用省略式n't，而应将not置于条件句之后。本题意为：若不是有水库，我们绝不能战胜干旱。
