非谓语动词
非谓语动词-不定式
1) 形式 主动形式 被动形式
一般式 to do to be done 完成式 to have done
to have been done 进行式 to be doing 完成进行式 to have been doing
a) 完成式: 不定式的一般形式所表示的动作, 通常与 主要谓语表示的动作(状态)同时(或几乎同时)发生, 或 是在它之后发生. 假如不定式所表示的动作, 在谓语所 表示的动作(状态)之前发生, 就要用不定式的完成式.
d) 被动式: 当不定式的逻辑上的主语是不定式 所表示的动作的承受者时, 不定式一般要用被 动形式. It is an honour for me to be asked to speak here. He wanted the letter to be typed at once. This is bound to be found out. There are a lot of things to be done. She was too young to be assigned such work.
He pretended not to have seen me.
b) 进行式: 如果主要谓语表示的动作(状 态)发生时, 不定式表示的动作正在进行, 这时要用不定式的进行式. You are not supposed to be working. You haven’t quite recovered yet. We didn’t expect you to be waiting for us here. He pretended to be listening attentively.
这类结构转换为被动语态时, 后面的不带to 的 不定式一般还原为带to 的不定式. She was made to tell him everything.
b) 在 had better, had best, would rather, would sooner, would just as soon, might (just) as well, cannot but 等搭配之后, 动词不定式也 不带to. I’d rather not have eggs and bacon for breakfast. They cannot but accept his term.
I am glad to have seen your mother (= I am glad I
have seen your mother). (比较: I am glad to see you.)
He is said to have written a new book about
workers.
