prep2-9

9,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

答案选B，不明白为什么A不对呢？请求帮忙

我觉得这道题的解题关键是risk of doing sth 的搭配。至于one in a million chances 或one chance in a million 都对

顶。同问。

as little risk as one chance in a million of 这里面as as的用法太怪异了。

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

应为这里risk和chance都是of doing，所以可以理解为，

…as A as B of doing…

one/a chance in a million是一个整体；如，

She has only a chance in a million of getting the job.

We have not a chance in a million of winning.

We haven’t a chance in a million of winning.

A further 58 associations had less than one chance in 100,000 of being wrong.

谢谢楼上的！

这道题我一开始只是觉得读起来不顺。细想，应该是

as本身是adv.，这里as little risk，as其实修饰的是risk。如果非说as是修饰little的也未尝不可，只是我从来没有碰到这样的用法，google了一下也没找到。

大家能找到这么用的例子么？

But some feel that those experiments, because of the potential for escape from the lab, put us at as much risk as the natural evolution of the virus.

谢谢，好例子啊。是从这里来的么？

OG/GWD中有这样的例子么？
