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.
as little risk as one in a million chances to cause
as little risk as one chance in a million of causing
as little risk as one chance in a million that it will cause
a risk as little as one chance in a million for causing
a risk as little as one chance in a million for it to cause
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
1. risk of doing sth., risk doing sth. 是固定搭配，由此排除A/D；
2. one chance in a million 是固定搭配，表示几率很小。由于修饰risk时，as little risk as one chance in a million 和 a risk as little as one chance in a million都是正确的表达方式。由此排除A；
3. C：that后面it引导的是定语从句，修饰的对象是risk。而从逻辑意义上看risk不应该cause cancer。排除C；
4. E：a million for it to cause 表达错误。排除E。
5. as many NOUNs as...
as few NOUNs as...
as much NOUN as...
as little NOUN as...
