动词不定式作表语，表示主语的内容。主语常常是表示意向、打算、计划的词，如wish, idea, task, purpse, duty, dream, jb等。一般来说，动词不定式作表语往往表示具体的某个动作，多表示将来。eg   His task is t crrect these papers. （具体的将来的行为）
The purpse f the bk is t prvide a cmplete guide t the university.Her dream is t make a mvie.The ld man’s jb is t take care f the flwers in the garden.
注意：不定式在作表语时，当前面的主语中有d的某种形式时，作表语的不定式可以省略t。eg What yu shuld d next is (t) help him with his English。 The nly thing he can d nw is (t) give up the plan.
动词-ing形式和不定式同样都可以充当表语，两者的区别在于不定式表达是具体或是将来发生的动作，而动词-ing形式则表示抽象的一般行为。e.g. His jb is delivering the letters t their destinatins. My jb is t lk after the sister when Mm is cking.
