1．可以直接作主语。如：To see is to believe.但在英语中，常用it作形式主语，真正的主语即动词不定式放在后面。 It's wrong to play tricks on other people.It's our duty to keep our environment clean and tidy. 动词不定式在句中作主语时，常放在It is＋adj.(形容词)＋to do sth或It is＋n.(名词)＋to do sth it仅作形式主语。 2．动词不定式与动词­ing形式作主语时的区别 (1)表示一般的、泛指的或习惯性的行为用动名词；表示具体的、一次性的或将来的动作用不定式。 Swimming is fun in summer. 夏天游泳是有趣的事。 Swimming in this river is a great pleasure. 在这条河里游泳是件非常快乐的事。 注：有时这种区别并不很严格。但要注意：主语和表语要用同一种形式；平行结构中要用同一种形式。 To see is to believe.＝Seeing is believing. 眼见为实。 Fishing is his favorite hobby，and collecting coins also gives him great pleasure. 钓鱼是他的爱好，集邮也给他带来极大的乐趣。 (2)口语中，陈述句多用不定式作主语，而疑问句却总是用动词­ing形式作主语。 Is doing morning exercises good for your health? 做早操对你身体有好处吗？ (3)下列句子中通常要用动名词 It's no good/use talking to him. 找他谈是没有用的。 It's useless discussing the matter. 讨论此事无益。 There is no stopping him. 无法阻止他。 No parking! 禁止停车！ (4)下列句中通常要用不定式 It took us two hours to get there. 去那里我们花了两个小时。 It's foolish of him to do so. 他这样做是愚蠢的。 It is necessary for us to learn English well. 我们有必要学好英语。 [对点集训1] 完成句子 ①犹豫不决就意味着失败。 ___________ means failure. ②这样做是削足适履。 __________ is to cut the foot to fit the shoe. ③人们为钱而结婚是错误的。 It would be wrong for people __________________. 二、不定式作表语 1．不定式作表语时常见的动词：不定式作表语时，一般紧紧跟在系动词后面，如be，seem，remain，appear，get等，用来说明主语的内容。 My job is to help the disabled. 我的工作是帮助残疾人。 The best way to build a great team is to gather a group of the most talented individuals. 打造一支出色的队伍最好的方法是把最有才华的个人聚到一起。 The efforts made by the Tanzania National Park Authority seem to be paying off. 坦桑尼亚国家公园管理局所做的努力似乎正在得到回报。 2．不定式作表语常表示计划、安排、目的、结果、愿望、禁止、征询意见等。 You must be patient and persistent if you are to succeed. 想要成功，你必须有耐心和毅力。 3．主语或主语从句中若带do，则不定式作表语时可省略to。 All you do now is (to) complete the form. 你现在要做的就是把这张表填好。 The only thing to do now is (to) go on. 前进是现在唯一的出路。 4．某些动词的不定式作表语，用主动形式表被动意义。常用的这类动词有blame(责备)，seek(寻找)，let(出租)等。 This car is to let.此车出租。 The young man felt he was to blame for this traffic accident. 那个年轻人觉得这次交通事故怪他。 5．动词­ing形式作表语时，多指抽象的、概念性的动作，说明主语的性质或特征；不定式作表语时，说明主语尚未发生的动作，或表示将来的动作。 My job is to clean the rooms every day. 我的工作是每天打扫房间。 Our job is playing all kinds of music. 我们的工作是演奏各种各样的音乐。
