在復合結構中的不定式

不定式的復合結構是指有些動詞帶賓語后再帶上不定式，作賓語的補足語。前邊已提到過，在這種結構中賓語是不定式的邏輯主語。

1、有很多這樣的動詞可以跟賓語及其(或)補足語不定式,如：advise, allow, ask, enable, beg, cause, drive, encourage, expect, forbid, force, hate, get , intend, invite, like, permit, persuade, pretend, remind, say, teach, tell, trust, urge, want, warn等表示“致使”等意義

26) The company manager may enable the men who tend the machines a large panorama(全景)of possibilites.

[A] to see[B] see[C] seeing[D] seen

27) Did you intend us the new method?

[A] to use [B] using [C] our having used [D] the using of

28) The teacher encouraged good compositions.

[A] us write[B] us writing[C] us to write[D] our wrting

2、在某些成語動詞如 arrange for, call on, care for, count on, count upon, depend upon, long for, prepare for, prevail upon, rely on, vote for, wait for等后面，也可以跟賓語加不定式的復合結構

We are waiting for the bus to come./ They voted for Wang Gang to be the monitor. / Don't count on me to do that.

3、另外，表示感覺的動詞 see, hear, feel, watch, notice, observe和have, let, make后的賓語可接不帶to的不定式(help后不定式可帶to也可不帶to)

29) I often heard him that his family was well descended.

[A] said[B] say[C] to say[D] to be said

30) We must have a person them build the house.

[A] see[B] to see[C] will see[D] shall see

31) You would become irritated [A] if you watched [B] the correspondence to pile up [C] on your desk day by day [D] .

4、表示心理狀態的動詞像consider, declare, find, prove, think, know , believe, discover, feel(=think), imagine, judge, pretend, suppose, understand等詞的賓語補足語不定式一般是to be(或動詞的完成時態)

32) “You've been taking a lot of nice photographs.”Thanks. I'm considering a professional photographer.

[A] becoming[B] about become[C] to become[D] over becoming

而且，在consider, declare, find, prove, think等動詞后的to be 是可以省去的。如：She considered me a scholar. / They found him gulty.
