还是不明白这里说的A,B的区别,请指点!!!
The gyrfalcoon, 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
这题选a
解释这么说的,the use of more instead of greater inappropriately implies there are now more numbers, rather than more gyrfalcons.
还是不太明白。。。
number的比较只能论大小不能用多少来衡量
比如说5大于(greater),不能说成5多于(more)3
所以OG的意思是如果用more只能说成鸟本身的比较,而不是鸟的数量的比较
