[求助]PREP2-9

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

对于答案是B我没有问题，只是我不明白这里为什么要用Little。

不是little 只可以修饰不可数名词吗？这里的risk 应该是可数的吧，否则也不会在 (D) 和 (E) 里出现 a risk 了。

我想这里的little 是不是small 的意思吧。

可能我的问题有些蠢了，大家不要笑话。

一点都不蠢，很不错的问题

查了一下LOCDE里risk的意思：

发现risk既是可数名词，也可以做不可数名词。不管是few risk还是little risk，google和answer上都可以搜到

希望可以给你帮助

后来我仔细想一下，这里可能是说这个risk 很小，不是来形容数量来着，是形容risk 的性质。是一个大risk 还是一个小risk. 所以和risk 是可数还是不可数没有关系。
