譬如to be doing.
觉得很乱 不定时不是表示将来吗 怎么后面加了个进行时
譬如to be doing.
不定式的大体方向是表示在谓语动词后发生,即将来,但是在非谓语作宾语的时候,有些动词固定要接不定式,比如refuse,decide,promise 等；或者不定式作原因状语时,此时,就不是将来的意思啦.
不定式的进行式表示与谓语同时发生的意思.例如：She was surprised to be seeing her old friend.
seems to be doing pretend to be doing be reduced to doing be eager to doing to be done=doing? be important to doing 对吗 be used to doing sth? be due to doing sth. advice to be doing sth be due to doing sth? be equal to(doing)sth. Be conductive to doing 是什么意思?
