200。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.
(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(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，想问E为什么不对？

ETS解释是；choice E, The
finding of much larger populations .. . than in those that is an improperly constructed comparison.不太明白，这不是也表示在用pesticide的土壤中比不用pesticide的土壤中发现更多microbe吗？

谢谢

这个结构会有歧义：the finding of larger populations in soils A than (the finding/populations) in soils B.

sunshining

谢谢斑竹，看来逻辑意思还是很重要，忽略了这层歧义

我的问题是为什么A：than in soils that are free of such chemicals中没有补出those？不补出than后面的主语不会造成前面的much larger populations和后面的in soils比较，这不是不可比的吗？到底在more than/as as结构中，什么情况下可以后面的主语可以不补出呢？

sunshining

A选项的比较很平行，比较的是。。。in soils with a relatively long history of pesticide use than in soils that are free of such chemicals

而且我觉得E的说法好象主语部分特别的长

ETS应该不太喜欢这种结构吧

e is wrong ,for we can complete the whole sentense like this

the finding of much larger populations of pesticide-degrading in soils with a relatively long history of pesticide use than (that )(finding of much larger populations of pesticide-degrading )in those(soils)that are free of such chemicals suggests one reason (that) certain  pesticides can become ineffective if used repeatedly in the same place.

here the sentense omits two that,especially the first that follow than that can not be omitted,so the og says e is an improperly constructed compararison.of course we need the second that to complete the whole sentense.

I agree on this point!

我本来也是这么排除D\E的，不过看了OG的解释说比较结构出了问题。又仔细查了前辈们对此的解释，可是没有看到很让我明白的。个人觉得，E的错误不在于省略，在于比较结构就不能像E的这种句式，什么“The finding of much larger...than..."，E的结构根本没法比较。不知道对不对，请NN指教。

The finding that there are much larger populations of pesticide-degrading in soils with a relatively long history of pesticide use than in soils that are free of such chemicals suggests one reason that certain pesticides can become ineffective if used repeatedly in the same place.

如果这么改一下，句子就是正确的了。可是结构不好，主语太长。

the finding of,在OG里，是无法表达finding地丰富含义的。所以OG的最佳答案，把finding的结果放在句首，再用: one reason is suggested by the finding that 来表示finding的内容。

相当于:...: it is suggested by.....
