My fatherlikes collecting stamps, but my mother doesn't.(用另一个句子表达同样的意思）
应该是: My mother doesn't like collecting stamps, but my father likes. 还是: but my father does.

如果按照原句的格式的话。
貌似应该是but my father does.
但是我觉得如果说 but my father likes好像也是可以的。。
话说这个练习我们这儿没有呢。

My mother doesn't like collecting stamps, but my father does.

按照语法  是my father does

my  father  does.

就应该是but my father does.

应该是but my father does

应该是but my father does

My mother doesn't like collecting stamps, but my father does.

我们说Yes,he does.不说Yes,he likes.是一样的道理。
