2020高考英語沖刺知識考點復習一
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:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(對等)
注:1).不定式作主語時,謂語用單數(shù)
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構中：
(1)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名詞+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
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。
Itisprobableforhimtocometothemeeting.(錯)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
