prep 2-9 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
Key: B
如果D和E改成a risk as little as one chance in a million of causing也就对了
1. 比较结构as adj. a noun. as... ：
as....as之间是可以加 adj+noun的，不过好像只限于几种形式(张振邦)：
as+adj.+不定冠词+单数可数+as I haven't seen as old a car as this for years.
as+adj.+零冠词+不可数名词+as 对应 prep2-9 (见类似题链接)
as+adj.+零冠词+复数可数名词+as I don't smoke as expenesive cigarettes as those.
2. as adj. (a) noun. as = (a) noun. as adj. as，其中第一个as是adv. 什麼時候有a 什麼時候沒有？
根据考点上说的话，那risk是不可数的， as little risk as。。。是ok，那为什么可以a risk as little as one chance in a million of causing，as little risk as...=risk as little as才对吧。。？
