动词不定式作主语时,为了保持句子平衡,常用it代替它作形式主语,而将真正的主语—动词不定式后置,上面的例句常写为:It’s difficult to learn English well.1. 不定式作主语(subject)e.g. My job is to protect the world.2. 不定式作表语(predicative)不定式常用在系动词be, seem, appear,
get, remain等后作表语。 Seeing is to believe.
To see is believing.

quickly.如果主语部分有个表示不定式内容的do, 用作表语的不定式可省略to。3. 不定式作宾语(object)e.g. Jeremy Lin likes to play basketball.

allow, advise, ask, call, cause, encourage,
expect, force, get, help, invite, need, order,
prefer, remind, teach, tell, train, want, warn
等。1) 不定式在感官动词(feel, hear, listen to,
watch, look at, notice, observe)后;
2) 使役动词 (let, have, make)后, 但是在被
动语态中要还原to。不定式作宾补时不带to的情况3) 不定式用在介词but, except, besides后时,
如果这些介词前有行为动词do的各种形式,
那么介词后的不定式不带to, 相反则带to。e.g. She could do nothing but cry.

e.g. She is always the first to come and
the last to leave.something, anything, nothing, everything等复合不定代词常用不定式作后置定语。如果不定式是不及物动词, 则后面需加
适当的介词。

___. on1) Have you anything to send?
你有什么东西要寄吗?
2) Have you anything to be sent?
你有什么要(我或别人)寄的东西吗?(不定式to send的动作执行者是you)(不定式to be sent的动作执行者是

so as to, enough to, only to。6. 不定式作状语(adverbial)e.g. He spoke loudly (so as / in order)
to be heard.1) 表示目的: to
