问题 Certain pesticides can become ineffective if used repeatedly in the same place; one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
选项 A、Certain pesticides can become ineffective if used repeatedly in the same place; one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
B、If used repeatedly in the same place, one reason that certain pesticides can become ineffective is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
C、If used repeatedly in the same place, one reason that certain pesticides can become ineffective is suggested by the finding that much larger populations of pesticide-degrading microbes are found in soils with a relatively long history of pesticide use than those that are free of such chemicals.
D、The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason, if used repeatedly in the same place, certain pesticides can become ineffective.
E、The finding of much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in those that are free of such chemicals suggests one reason, certain pesticides can become ineffective if used repeatedly in the same place.
答案 A
解析 本题的题干更长，也是全划线。A读起来没有发现什么问题，仅发觉它用了被动语态(这一点暂时记在心中)；B中读到one reason就可以停下来，因为这里one reason不能作过去分词短语used的逻辑主语；C同理，错；D中读到is suggestive of，就该停下来了，因为这种表达在前面已提过多次，不如用一个动词suggest简洁；E中读完后发现one reason之后是一个完整的句子。从句意上理解，该句子是对reason的同位解释，也就是说，这里缺一个同位语从句的标志词that。如果此时对D选项还有印象，会发现D也犯有与E相同的错误，缺同位语从句标志词that。由此可确信A是正确答案。那么A为何用被动语态呢?这是因为本句主语太长，用主动语态会显得头重脚轻。另外，C中those之前缺in，E中还有一大错误，即finding之后用of短语修饰的表述问题。还记得第一章中的抽象名词后用of还是用that从句进行补充解释的判定原则吗?此句中E用。随语修饰是不妥的。
