标题: OG(紫) SC Q72 分号的使用
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（A）

    

(E) extinction, now with numbers five times greater than

A is Correct. The original sentence correctly uses a singular pronoun, "its", to refer to the singular antecedent "gyrfalcon", and it properly uses the construction "its numbers are...greater than".

我错误的选择了D，做题的时候概念很模糊，觉得每个选项都拿不准。没有选A的原因是觉得”its numbers are now five times greater than"后面少了什么，感觉不能直接跟"when...."

请大家分析一下这道题的做题思路， 谢谢！！

A中”its numbers are now five times greater than"后面为什么直接跟时间呢？这里我是什么语法知识点不足啊？
请NN指教！谢谢！

省略了 than (its numbers were) 。注意一般后面的时间用时间状语从句的话，不补出主语和助动词是可以的，因为不会有歧义

但是当时间为 X years ago时就要补出，因为X years是个名词会有比较对象歧异

原来是这样，谢谢ranning! 你的语法点简直掌握到炉火纯青的地步了。。。
我做题很多都是靠感觉，感觉对了就蒙对，完全没有扎实的底子，哎。。。还是啃OG吧。
