PREP 44请教高手

44. 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—one指代risk

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--it重复

D. a risk as little as one chance in a million for causing—chance of doing or to do

E. a risk as little as one chance in a million for it to cause—for it 罗嗦

D为什么错？我查了一下，for causing对，a risk as little as 也很常见

”so those on 25 cigarettes a day or more have a risk as little as one-tenth that of non-smokers,"

同请教这道题

不是很清楚其语法点

此题考点是  risk of

知道考点只需20秒钟

那醉兄是如何来判断该题考点是risk of doing还是chance of doing的呢？

逻辑意思很明显。你用不同方式翻译一下，后者不合理。

而且语法上看 ：one chance in a million of causing表达不正确

risk在这里应该表示风险率的意思

one change in a million正好表示一个比率,修饰risk非常好

到底chance for 是对还是错？
