2. _______________(不止一个人觉察到)her agitation.

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)wed never have been able to beat the drought.

答案与解析：

1. is a product of the evolutionary process

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

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 Partys 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。)
