三、 不定式作表语

1. 一种情况为主语是不定式(表示条件),表语也是不定式(表示结果)

To see is to believe/ To work means to earn a living.

2. 另一种情况主语是以aim, duty, hope, idea, happiness, job, plan, problem, purpose, thing, wish等为中心的名词,或以what引导的名词性从句,不定式表语对主语起补充说明作用

11) The function of Louis Sullivan's architecture was providing [A] large uninterrupted floor areas [B] and to allow ample light [C] into the interior [D] .

12) The most important [A] thing is negociate [B] with them about [C] the future of [D] the plant.

四、 不定式作定语

1. 不定式作定语修饰名词或代词,它只能放在它所修饰的名词或代词后面。这时被修饰的名词与不定式之间有逻辑上的主谓关系

14) Billie Holiday's reputation as a great jazz?blues singer rests on her ability emotional depth to her songs.

[A] be giving[B] are given[C] being given[D] to give 另外,有些词的不定式定语有主谓关系,如除了上述例句以外,还有些词常跟不定式作定语。这些词主要有decision (to make), (a) need (to eat), opportunity (to speak),reason(to learn a foreing language), time (to sth)等。

2. 动词不定式作定语往往有一层动宾关系,即所修饰的名词是不定式的宾语

15) Alice was having [A] trouble to control [B] the children because there were [C] so many [D] of them.

16) There are so many reference books for matriculation of postgraduate and I haven't decided which book .

[A] to do … to talk[B] doing … to talk to

[C] to do … to talk to[D] doing… to talk

3. 因为不定式所修饰的名词是不定式的宾语,所以如果不定式动词是不及物动词,那么就要在动词后加上相应的介词

He has a lot of trifles to deal with./ I had got no place to live in./That girl has nothing to worry about./the subject to concentrate on. / He has a strict teacher to listen to. / She has four children to look after. / She had a sick mother to live with. / This is the very person to sell your ticket to.

还有固定搭配的不定式表示结果:so…as to; such(…) as to …; enough to…; too…to…; in order to … 等
