想問一下
不定詞跟動名詞放句首的用法
最近考卷看到一種題目
_______ regularly is important.
To exercise/Exerciseing
答案是To exercise但為什麼不能選Exerciseing
求解題！！

Answer 1

Kite

可以把句子回推
==>It is important "to exercise" regularly.
這裡是用to exercise, 所以推回去就是 To exercise regularly is important.

那動名詞什麼時候可以放句首

Kite

當動詞當主詞的時候(e.g. "Drinking" water everyday is important.)
上面那句的主詞是"To exercise regularly"，就不是用動名詞當主詞
