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，我怎么就觉得2个比较对象：risk和one chance in a million不对等呢，还是在这里as......as....根本就不是一个比较结构，求解答。比较问题真是让我纠结，总是错。

首先是代词的数，
c项中的that it will cause, E项中的for it to cause. it指代的是上文中的toxic substances, 但是彼处是复数，此处是单数，矛盾。
另外it不能指称risk, 否则意思变成了’风险导致癌症‘，而不是’导致癌症的风险‘。
所以排除C E

A项中的one in the million chances的说法不对，因为所要表达的不是‘在百万机会中的一个机会’，而是 ‘在百万情况下的一个情况的机会’ 把省略的部分补充完整以后是这样：'one (case) chance in a million (cases)'
或者不用加 case，而直接指百万分之一的机会亦可。
A项中的million chances表示的是百万机会，错。

D项中如果把中间部分去掉的话，我们得到了a risk for causing的结构，但是这里的意思和a risk of causing cancer完全不同，
参考这个句子：
His failure to follow the professor in class puts a risk for passing the exam.
他上课没有跟上教授，给他通过考试带来了风险。

所以risk for causing cancer的意思是给导致癌症这个目的带来了风险，与句子本义完全相反。所以排除D

我有一个问题， present a risk, 还是 present risk. 这里应该有一个冠词的吧。

B对的原因在 1 little risk和one chance in a million这两即风险晓得只有百万分之一。2 risk of doing固定用法，risk to do 没见过。

A错的原因之一就是 as little risk as one in a million chance ,one这里语法上代指名称risk, risk 和 chance不是一类的不能"in a million chance"
轻拍~~

说说这里的as.....as的问题

to present as little risk as one chance in a million of causing caner
to carry as many as 7 people.
to arrive from as early as 6 a.m. to as late as 11 a.m.
to be effective at temperatures as low as -30 degrees.

在举例说明呢。
