Q30:

According to public health officials, in 1998 Massachusetts became the first state in which more babies were born to women over the age of thirty than under it.

than

than born

than they were

than there had been

than had been born

Please teach how to judge between A & B? thanks!

B的错误在于即便要补出动词，也应该是表被动的助动词而不应该是实义动词；此外，当比较对象的主谓结构相同时可以全部省略，而只保留有差异的介词部分。

看看这道题：

129. As a result of the continuing decline in the birth rate, less people will enter the labor force in the 1980’s than did in the 1960’s and 1970’s, a twenty year period during which people born after the war swelled the ranks of workers.

(A) less people will enter the labor force in the 1980’s than

(B) less people will be entering the labor force in the 1980’s as

(C) fewer people will enter the labor force in the 1980’s as

(D) fewer people will be entering the labor force in the 1980’s as（E）

(E) fewer people will enter the labor force in the 1980’s than

谓语动词可以省略么？

楼上mm的例子的谓语部分（时态）不一样，所以不能省略吧？偶觉得。

如果前面是do in 2000's，后面可以是will(do) in 2010's

如果前面是will do in 2010's,后面当然只能是did in 1990's

搜了搜Boston Magazine的记载：

 In 1996, Massachusetts became the first state in which more babies were born to women 30 and older than to women under 30, and the trend has only escalated since. 

比较一下看看。

布瓜丫丫

这样看来是A没错了，to woman 在这里省略了

楼上的两位真是穿越时空对话亚！我想问问did是指代entry得过去时吧，再问问哪里有关于这种类型比较的解释呢？

OG上就有，还不少，do代替前面出现过的实意动词，主要为了引起行文变化，避免重复和死板。

另外，动词也可elegantly重复。
