(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 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.（A）
(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.
答案是a, 但是我觉得结构上不平行：there are much larger populations ....in soils with ...than in soils that..... than 后应该补出代词those 指代population 才对呀？请指教。

比较的是populations,但than后可以省去those
populations in soils are more than those in
这个时候才补those
我就举这个两个例子了
大家体会体会
再举一个
owing and living in a house is still goal as it is ....
it 指代owing and living in a house
要再举还有很多
不知道大家看出问题来了没
多谢gigi，继续请教：
og:
In choice E, The finding of much larger populations .. . than in those that is an improperly constructed comparison.
笨鸟：
1. 正确选项中为什么比较的时候后边还用in soils 而不用those? 因为这样更清楚，避免了代词指带的不清楚。
可是e中those前有in和in soils 平行,怎么会指代不清呢？

问题同上！
我连LES问的是什么都没看明白...
再问:A中than后补全应是什么样?
there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than there are populations of pesticide-degrading microbes that free of such chemicals in soils
再问:E中than后补全应是什么样?
larger populations are there in soils A than populations are there in soils B.
欢迎指正！
再问:E中than后补全应是什么样?
i think in e,than that(the finding of much larger populations ) in those(soils)that are free of such chemicals suggests one reason(pay attention to here,for that is needed here)that ,,,,,,
besides,i think than there are populations of pesticide-degrading microbes that free of such chemicals in soils should be
than there are populations of pesticide-degrading microbes in soils that are free of such chemicals rather than vice verse
比较的是populations,但than后可以省去those
什么时候可以省略啊？这点我还没总结出来。
请阅读置顶的精华点总结, 有比较结构省略问题的讨论.

同问！
我个人感觉e的问题在于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 做of的宾语是否合适 很显然这里finding后面应该跟同位语从句起解释说明的作用而不是接of的介词短语
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这句话做主语总觉得怪别扭的 总觉得中间少了点什么 但是又加不上去 这种 N+of+more N than ......的结构存在吗 关键是后面的介词宾语是否成立？？？？请nn指点
there be S.+attr1. than attr2.句型比较两个attr.（定语），记住这个句型就好了。参看大全35，205，359（本题）。
