动作。（不定式作主语往往表示具体的特别是将来的动作）如：

(抽象的动作) 说着容易做着难。

2.有时可用It做形式主语,代替V-ing短语，用于下列句型中：

It is/was a waste of time/a pleasure doing

It is/was no good/use doing

It is/was useless doing

It is/was worth/worthwhile doing

记忆口诀：考虑建议盼原谅; 承认推迟没得想

3.补充：Give the verbs that use ‘to do’ only as object 记忆口诀: 决心学会想希望；拒绝设法愿假装

pretend

提供承诺选计划；同意请求帮一帮
