白勇第7章-36题

1.        In the 1980’s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970’s.

(A) twice as fast as

(B) twice as fast as it was in

(C) twice what it was in

(D) two times faster than that of

(E) two times greater than

答案是c，白勇说b错是因为it was in the1970是个句子，和名词短语不对应，我觉得可以这样说啊~~~

顶下

我一开始也是这么认为的但是在Google了一下fast rate，似乎有这样的用法。可是白勇这么一说真让人不明白，我就是选B的，大牛帮看看吧

我也在想这道题 看了一个美国人的解释 还是和fast有关

The key here is that we cannot use fast (or slow, for that matter) for rate--we don't say a fast or slow rate, do we? Isn't it more natural to say a high or low rate?

I call these "measurement" words, and they come up from time to time in ETS grammar. For example, we don't say a hot temperature, we say a high temperature, right?
The correct answer provided is C.

smiling_mm和fighting_mm讲得有道理~~是fast有问题
