    不定式做主語:
    不定式做主語一般表示具體的某次動作。===動名詞doing表示習(xí)慣的,經(jīng)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(shù)
    2).當(dāng)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(jié)構(gòu)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 / 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.

    不定代詞的用法
    不是指明代替任何特定名詞的代詞叫不定代詞。
    常見的不定代詞有 all, both, each, every, some, any, many, much, (a)few, (a)little, one, ones, either, neither, other, another, no, none 以 及含有 some-, any-, no-等的合成代詞(如:anybody, something, no one) 。
    這些不定代詞大多 可以代替名詞,在句子中作主語、賓語、表語或定語。但 none 和由 some, any, no, every 構(gòu) 成的復(fù)合不定代詞(如 somebody 等)只能作主語、 賓語和表語。 every 和 no 只能作定語。
    不定代詞可作主語。當(dāng)作主語時,要明確這一不定代詞究竟是單數(shù)還是復(fù)數(shù),以確定它和 謂語動詞在人和數(shù)的一致。
    不定代詞還可作定語。當(dāng)作定語時,應(yīng)該注意其所修飾的名詞是可數(shù)還是不可數(shù),以確定 這個名詞用單數(shù)還是復(fù)數(shù)。
    例: Much has been done to fight pollution;each of them has got a present.
    many, few 和 both 用于可數(shù)名詞,表示復(fù)數(shù)概念。
    All, both 和 each 和含有 every 的復(fù)合代詞用在否定句中只表示部分否定。
    例:Not all the students have been to the Austrlia. She can’t work out both of the difficult problems. Everybody cannot work out the problem.
    Neither,none 和含有 no 的復(fù)合代詞表示全部否定。
    例: None of us can answer the question. Neither of the questions is right.
