这题我还有问题.

A:since 1990 the global economy has grown more than it did...我觉得有问题. did用的并不合适.因为前面没有出现实意动词可以用did代替. 前面是has done的形式. 用did do的原则是: 主句动词和比较从句动词相同, 比较从句动词可以用did 或do代替. 比如说: I run more fast than you do. do是替代前面的实意动词run.  

但本题,前面是has done.不是实意动词.所以我认为后面did并不合适.

不知道为什么A能算正确?

请指教.

看看这个例子：大全763

The guiding principles of the
tax plan released by the Treasury Department could have even a greater
significance for the economy than the particulars of the plan.

(A) even a greater significance for
the economy than

(B) a significance that is even
greater for the economy than

(C) even greater significance for
the economy than have

(D) even greater significance for
the economy than do（D）

(E) a significance even
greater for the economy than have

答案D，大全简注：could后是原形do，than后面要用do替代实意动词have。

从大全的简注我们可以了解，than后面用do还是did，主要看主句系动词后面的实意动词到底是以什么形式出现——是do还是did还是done还是doing——再加上than后面的从句具体是什么时态，这个例子系动词could后面的have是动词原型，也就是do，than后面需要现在时态，所以就用do。但按你说的“主句动词和比较从句动词相同”才行的话，这个例题的D就应该改成than could do了。

你的这道题主句系动词是完成时的has done，than后面需要过去时，所以用did。

grow more是很顺口的表达呀，E错在what it did，it指代不明，did也指代不明。

补充一点,因为在选项里面是SINCE 1990,所以句子要用现在完成时

谢谢rosmarineMM. 我有些看法, 大家一起讨论.你说的这一题,than后面补do是因为前面有实意动词have.   do和have对应. 这里could表示可能性. 句子表达的意思是可能性和客观性相比较. 如果排除句意考虑的话,这题than后面仅仅补出could也是可行的. 根据有情态动词,助动词出现时, 比较从句往往省略verbal, 保留助动词或情态动词. (这里选项没有).

省略,替代的前提必须是可以还原, 就象你举的这题, do可以还原到have.  

而软件这一题, 我认为找不到一个可以还原的对象.  就象OG这一题:

92. Never before had taxpayers confronted so many

changes at once as they had in the Tax Reform Act of 1986.

(A)  so many changes at once as they had in

(B)  at once as many changes as

(C)  at once as many changes that there were with

(D)  as many changes at once as they confronted in  (D)

(E)   so many changes at once that confronted them in

注意D: 这里OG是把整个动词都补出来了confronted, 而不是用did.  以为前面是had confronted. 我个人认为这题

和软件那题是一样的情况.  软件那题,用did个人感觉并不妥当.
