According to public health officials, in 1998
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)
下面这个例子好理解。
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?
对么?for example: He has more apples than I do.
do 不能省掉
open to discuss
