GWD-16-30

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.

 

1. than
2. than born
3. than they were
4. than there had been
5. than had been born

请问：为什么 than under it 就可以了。不用加主语，或者谓语。

請參考其他大俠總結的比較的省略。

本題可還原為：

(more)babies were born to women over the age of 30

(than)babies were born to women under the age of 30

要比的是"babies were born to women",the age of 30用it取代掉,所以主詞加動詞都可一起省略

不會造成歧異.

比較下面的個例子：

I love more cats than you(比起愛你,我比較愛貓)??

I love more cats than you do(我比你更愛貓)   

wangtsong

下面这个例子好理解。

wangtsong

但是假如改成主动句：woman over the age of 30 born more babies than they do under the age of 30.

对吗？

前后的主谓一样,后面的主谓可省略.

对么？for example: He has more apples than I do.

do 不能省掉
