看这个：答案C

Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than it was in any previous election.

1. a greater proportion than it was
   
2. a greater proportion than
   
3. a greater proportion than they have been
   
4. which is greater than was so
   
5. which is greater than it has been

这是GWD-1-Q16，我想CD上大家讨论的答案是B，所以C中间的时态是否正确没有定论。

关于这道题，倒是可以参考OG中的拿到拿破仑的题目，非常类似，所以选择B理由充足。

继续问GWD17－38！！！！

我也觉得奇怪。如果b改为the Y chromosome of a single ancestor who was thought to live就很好。up！

B不对：你指这道题吧！：

Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.

(A)    they had in their previous campaigns

(B)    their previous campaigns had had

(C)    they had for any previous campaign

(D)   in their previous campaigns

(E)  for any previous campaign   

选择 E

你再看这两道题：

------A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than five years ago.

(A) making the construction industry’s economic health much more robust than five years ago A不对

(B) and make the construction industry’s economic health much more robust than five years ago

(C) making the construction industry’s economic health much more robust than it was five years ago

(D) to make the construction industry’s economic health much more robust than five years ago（C）

(E) in making the construction industry’s economic health much more robust than it as five years ago

再看：

-----The use of chemical pesticides in this country is equally extensive or more so than ten years ago.

(A) equally extensive or more so than ten years ago

(B) equal to or more extensive than ten years ago B不对

(C) as extensive as ten years ago or more

(D) equal to, if not more, than ten years ago（E）

(E) as extensive as it was ten years ago, if not more so

than做比较时前后：必须一致。可以省略，

running非常感谢，也非常佩服你找例子的本领。

我同意你后面两个例子，但是第一个例子那个have been我有点不能接受，而且GWD17－38那个时态也是怪怪，也许他们属于同一个考点（如果你的第一个例子答案是C的话），除了例子，再给解释一下为什么吧？

我倒是同意4楼bluevironika的改写。

这里是不定式to的过去时态,不是现在完成时,故可接about 140,000 years ago.

祝明天考的好.

XUANYA2005 你却下线了 郁闷

E.the Y chromosome of a single ancestor whom it was thought had lived 我觉得it 出现不舒服 whom也是为了it出现而改成宾格的。

D.the Y chromosome of a single ancestor who is thought to have lived    have lived表示ancestor生活在is thought 之前

不知道理解得对不对 请NN指正。

虽然考完了，继续讨论。

如果要表示have lived 是is thought 之前，那么普通规则上，应该也不能用have啊，因为现在完成时表示，过去发生现在还在继续的事情啊，那个家伙肯定不能现在还活着吧？

完成杀G大业了，正是太高兴了。
