不定式的其他用法
too…to 结构通常表示否定意义:

enough…to结构则表示肯定意义:

如果要说明不定是表示的动作是谁做的; 可以在不定式前加一个for引起的短语:

在以某些形容词(如 kind; good; nice; wise; unwise; clever; silly; wrong; right; foolish; stupid; careless; considerate; rude; naughty; impolite等)作表语时; 不定式前可加一个of引起的短语; 来说明不定式指的是谁的情况:

在某些动词后(或成语中); 常用(或可以用)动名词的一般形式; 尽管动作是在谓语所表示的动作之前发生的。

被动式: 当一个动名词逻辑上的主语所表示的是这动作的对象时; 动名词一般要用被动形式。

现在分词短语有时可用作时间状语; 相当于when引起的从句:

如果不是在句子开头; 这个结构常常可以用名词的普通格(或人称代词宾格); 这比用所有格更自然一些。
