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.
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 1970s.
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
各位NN,这道题已经有讨论帖详细的说明了关于AB选项中 greater/more的问题, DE选项中,with短语错误的修饰了extinction的问题,than比较的对象是now和when的问题。
但是有关于fivefold的用法有什么问题吗。
OG答案里C/D 的解释都有:Fivefold the numbers they had is awkward and nonstandard and implies that there are now more numbers , rather than more gyrfalcons. 我不能理解,NN们能就fivefold的用法讲一下吗??
