4、 语法 :动词不定式的用法
动词不定式在英语句子中为非谓语动词的一种形式，即to do，也就是to 动词原形，没有人称和数的变化。其否定形式直接在前面 not，即not to do。实际上动词原形也可以称之为省略to的动词不定式。主要有以下用法：
1．动词不定式作主语。作主语时一般由形式主语来代替动词不定式，目的是防止在句中"头重脚轻"。 例如：It is difficult for us to learn English well.
2. 动词不定式作宾语。作宾语时跟在及物动词之后。
例如：want to do.
plan to do.
need to do.
hope to do.
refuse to do.
like to do.
love to do.
forget to do.
remember to do. etc.
3. 动词不定式作宾语补足语。
例如：want sb to do.
ask sb to do.
tell sb to do.
teach sb to do.
allow sb to do.
encourage sb to do. etc.
4. 动词不定式作目的状语。例如：To get to school, they went on a ropeway.
5. 动词不定式作定语。不定式在句中作定语，放在被修饰的名词或代词之后。 例如：I want something to eat.
6. 动词不定式作表语。不定式作表语表示具体动作或将来动作。
例如：My job is to look after the little children.
