不定式做表语与动名词做表语的区别？

不定式作表语表示具体动作或将来动作；动名词作表语表示抽象的一般行为。 ①To be kind to the enemy is to be cruel to the people. ②My chief purpose is to point out the difficulties ofthe matter. ③What I would suggest is to put off the meeting. 当主语和表语都是不定式时，其含义一是条件，一是结果（例①）。当主语是aim,duty,hope,idea,mista ke,plan,purpose,suggestion等为中心词的名词词组（例②）时，或以what引导的名词性分句（例③），不定 式说明主语的内容。 ④Our work is serving the people. ⑤What he likes is taking a walk after supper. ⑥The story told by Mr.Wang is interesting. ④⑤句动名词作表语，与主语部分可以转换，如Serving thepeople is out work,而⑥句中是现在分词作 表语，说明主语的性质、状态，现在分词具有形容词的各种特征，另外，动名词作表语还应与进行时态区别开 来。
