A. temperatures as low
B. temperatures so low
C. as low temperatures
D. as few
E. as little
温度可以和-30比?
c有何不可?
温度是跟–30 degrees Fahrenheit(华氏-30度)在比;另外at temperatures就是一种固定搭配,表示一种温度的状态,比方Water freezes at 0 degree celsious.
介词后面当然是跟名词啦,at as...这像什么样子啊...
但是我总觉得前面温度是一个定义,后面多少度是一个具体数,两者可比不像是gmac爱较真的性格。。。
也许是自己较真了。。。
at as错是否是因为连续两个介词犯忌了呢?
介词后面都是跟名词性的词或短语
