新课讲授

Step 1. Presentation

1. The usage of Infinitives

动词不定式

动词不定式（to + 动词原形）是非谓语动词的一种形式，在句中不能单独作谓语。不定式不受主语人称和谓语动词时态变化的影响。不定式在句中可以作主语、宾语、表语、定语、状语、宾语补足语等。

1. 动词不定式作主语，表示具体或一次性动作。

2. 动词不定式作宾语。

3. 动词不定式作状语，表示动作未发生。

4. 动词不定式作定语，通常表示未发生的动作，且常后置。

5. 动词不定式作表语。

6. 独立不定式：不属于句中的任何人或事物，而是修饰全句。

2. Infinitives as the predicative

1. 动词不定式的形式变化

2. 动词不定式的否定式：not to do

3. 动词不定式作表语

动词不定式作表语，通常用来说明主语的具体内容或者性质，常见的用来作主语的名词有aim, duty, dream, hope, idea, plan, ambition, purpose, work, job等

4. 动词不定式作表语的其他用法

(1) 表示根据安排将要发生的事。

(2) 表示注定要发生或不可避免要发生的事。

(3) 表示说话人的意志、职责、义务、命令，在意思上相当于must, should, ought to或have to。

5. 动词不定式和动名词做表语的区别

动词不定式和动名词都可以作表语。但用法有区别：表示一次性的、具体的动作用不定式；表示经常发生的、日常的动作用动名词。
