一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。动名词doing表示习惯的，经常的动作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(对等)
注:1).不定式作主语时,谓语用单数
2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名词+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均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。
Itisprobableforhimtocometothemeeting.(错)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
