Mixed with an equal part of water, ethylene glycol, a compound commonly used as an automotive antifreeze, is effective at temperatures as low as –30 degrees Fahrenheit.

A.temperatures as low

B.temperatures so low

C.as low temperatures

D.as few(A)

E.as little

在A和C中间选不出来。C的解释是at后面缺少名词作宾语
但语法笔记下面有一道类似题

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


我感觉答案B这里present不是也缺少了宾语吗？？
求NN指点

翻了翻以前的讨论，名词+as...as...是惯用搭配，而as+形容词+名词+as...比较少见。
这种题目，哎。。。

表示也看到了C解释的这个问题...同问...
笔记当中也说了as adj. (a)noun. as=a noun. as adj as，感觉应该可以互换啊...

我觉得
第一题的at和第二题的present是完全不同的
efficient at后面加具体sth
