1、初三英语复习动词不定式人教版朗文【同步教育信息】一. 本周教学内容: 复习动词不定式 动词不定式(The Infinitive)是英语非限定动词(Nonfinite Verbs)中的一种。它不像限定动词(Finite Verbs)那样受到主语的人称和数的限制,不需要和主语的人称和数一致,没有人称和数的变化,所以称它为不定式。 动词不定式的基本形式是“to动词原形”,有时可以不带to。这里的to只是动词不定式的标记或符号,本身没有词义。动词不定式,由动词原形构成,就仍然有动词的特点,可以有自己的宾语和状语。e.g. to borrow a book , a book 作to borrow的宾语,
2、to go quickly , quickly 副词作to go 的状语,上述短语由动词不定式和它的宾语或状语组成,称为不定式短语(Infinitive phrases)。 动词不定式在句子中除了不能用作谓语外,可以作主语、表语、宾语、宾语补足语、定语和状语等句子成分,可以说它具有名词、形容词和副词的特征。 e.g. To use English well is not easy. (作主语) 用好英语不容易。 Marys wish is to become a doctor. (作表语) 玛丽的希望是成为一名医生。 I want to go shopping. (作宾语) 我想去购物。 Mr
