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 表示習慣的,經常的動作。
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,謂語用單數
2). 當主語較長,謂語較短時,常用it做形式主語,而將不定式放到謂語的後面。
it做形式主語,不定式放在謂語動詞之後常用於下列結構中:
(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 / ashame / 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主語,而probable不能用不定式作真實主語。
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等爲中心詞的名詞詞組 或以 what 引導的名詞性從句表示,後面的不定式說明其內容, 不定式作表語常表示將來或現在的動作或狀態。
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
以不定式結構爲賓語的動詞有:
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)
