prep 9 同级比较问题,急哈~

9. (24819-!-item-!-188;#058&001693)

The Environmental Protection Agency frequently puts mandatory controls on toxic substances that

present as little risk as one in a million chances to cause cancer.

(A) as little risk as one in a million chances to cause

(B) as little risk as one chance in a million of causing

(C) as little risk as one chance in a million that it will cause

(D) a risk as little as one chance in a million for causing

(E) a risk as little as one chance in a million for it to cause

答案是b是固定搭配，但我有个问题，b是同级比较，在刘振民的语法改错精解中这种as...as的同级比较应该是as+adj+a/an+n+as 为什么这里不是 as little a risk as one chance in a million of causing .....??

彻底晕了，因为这个把b给排除了，请大家帮帮忙~><

A 是说。。几率造成了癌症 显然不可能

B 说造成癌症的几率是百万分之一

一目了然

额？感觉LS好像理解错LZ的意思了。。

MM的意思是a risk和risk的单复数问题么？

查了下baidu,risk是单复数同型，没有具体看

本人拙见。。

risk 在这里作为概率讲是不可数 应该直接排除
