一、不定式做主語:
1、不定式做主語一般表示具體的某次動作。===動名詞doing 表示習(xí)慣的,經(jīng)常的動作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (對等)
注: 1). 不定式作主語時(shí),謂語用單數(shù)
2). 當(dāng)主語較長,謂語較短時(shí),常用it做形式主語,而將不定式放到謂語的后面。
it做形式主語,不定式放在謂語動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,但possible可以用不定式作真實(shí)主語, 而probable不能用不定式作真實(shí)主語。
It is probable for him to come to the meeting.(錯)
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
主語是以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,后面的不定式說明其內(nèi)容, 不定式作表語常表示將來或現(xiàn)在的動作或狀態(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 、動詞不定式作賓語
以不定式結(jié)構(gòu)為賓語的動詞有:
ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用動詞不定式作賓語
口訣(接不定式作賓語的動詞)
想要學(xué)習(xí) 早打算( want learn plan)
快準(zhǔn)備 有希望( prepare hope wish expect)
同意否 供選擇(agree offer choose)
決定了 已答應(yīng)(decide be determined promise)
盡力去 著手做(manage undertake)
別拒絕 別假裝(refuse pretend)
失敗不是屬于你(fail)
