    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: To finish the building in a month is difficult.
    To do such things is foolish.
    To see is to believe. (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)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 +名词+ 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。

    It is possible for him to come to the meeting.
    It is possible / probable that he will come to the meeting.
