高三英語必背知識點3
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.
