今天看prep08 正文P122发现一个问题！！！ 164题： 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 E. as little 该题解释，C选项由于at后面缺少名词作宾语，所以错。应该选A，temperatures as low as的结构。 又有补充解释： as adj. (a) noun. as = (a) noun. as adj. as
而在下面那道类似题链接中： 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 答案选B。
疑问出现了。。如果前一题不把这个as low temperatures as –30 degrees Fahrenheit的结构当做名词，说不能接在介词后面的话，为什么第二题又把这种结构接在了及物动词present后，这不是一样的道理吗？？？？
难道说as adj. (noun) as结构只能跟在动词后面不能跟在介词后面？？？也就是说它只能当动宾不能当介宾？？？？？？ 其实我一直以为as low temperatures as –30 degrees Fahrenheit相当于一个名词temperatures的。。因为有过很多例句：I haven't seen as old a car as this for years. I don't smoke as expenesive cigarettes as those.
。。。on toxic substances that present as little risk as one chance in a million of causing cancer这部分其实是。。。on toxic substances that present little risk of causing cancer of介宾就够就是搭配risk的
