OG251
The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970’s.
(A) extinction; its numbers are now five times greater than
(B) extinction; its numbers are now five times more than
(C) extinction, their numbers now fivefold what they were
(D) extinction, now with fivefold the numbers they had
(E) extinction, now with numbers five times greater than
答案：A。查过之前的帖子，对于AB之间区分的解释是“主语是numbers 数量不能more than”而应该用“greater than”。
这道题我想和另一道题放在一起比较下，因为我觉得是相似的考点：
大全937
With a total population of less than two hundred and fewer breeding females than ever before, the American crocodile seemed a decade ago to be in danger of disappearing.
(A) of less than two hundred and fewer
(B) lower than two hundred and less
(C) lesser than two hundred and fewer
(D) fewer than two hundred and less
(E) of fewer than two hundred and of fewer
答案：A。对这道题之前帖子的解释是“Use less when referring to statistical or numerical expressions.
e.g:
Sara is less than five feet tall
Your issue essay should be a thousand words or less”
这似乎是说当指一些统计量或者具体数量表达用less, 而单纯表达比较含义的“更少”用fewer。但是，是不是后面这种情况也得分可数不可数呢？比如less money and fewer staff？而且还有一点区别，就是fewer只有形容词用法，但是less既可以当形容词又可以当副词使用。
这个是我总结的关于fewer和less的区别。但是greater和more还是区分不开。请多多指教这类数量题的使用区别和解题关键! |
