一、不定式做主語(yǔ)：
1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞doing 表示習(xí)慣的，經(jīng)常的動(dòng)作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (對(duì)等)
注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)
2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的后面。
it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名詞+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
_注意: probable 和 possible 均可作表語(yǔ)，但possible可以用不定式作真實(shí)主語(yǔ)， 而probable不能用不定式作真實(shí)主語(yǔ)。
It is probable for him to come to the meeting.(錯(cuò))
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.
二、不定式做表語(yǔ)
主語(yǔ)是以aim duty hope idea intention plan job suggestion wish purpose task 等為中心詞的名詞詞組 或以 what 引導(dǎo)的名詞性從句表示，后面的不定式說(shuō)明其內(nèi)容, 不定式作表語(yǔ)常表示將來(lái)或現(xiàn)在的動(dòng)作或狀態(tài)。
eg :My idea is to climb the mountain from the north.
Your mistake was not to write that letter.
What I would suggest is to start work at once.
三 、動(dòng)詞不定式作賓語(yǔ)

ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用動(dòng)詞不定式作賓語(yǔ)
口訣(接不定式作賓語(yǔ)的動(dòng)詞)
