60、并且還能用what來提問主語或表語。My dream is to become a teacher.To obey the law is important. (dream, business, wish, idea, plan, duty, task做主語時常用)動名詞與不定式的功能區(qū)別不大,然而它更接近于名詞,表示的動作比較抽象,或者泛指習慣性的動作,有時也可以用it做形式主語,做表語時可以和主語互換位置。It is no use saying that again and again.Teaching is my job.分詞無名詞的性質(zhì),不能做主語。但是有形容詞的性質(zhì),可以做表語,多表
