英语《主谓一致》教案.doc

主谓一致在英语句子里，谓语受主语支配，其动词必须和主语在人称和数上保持一致，这就叫主谓一致。主谓一致是指：1） 语法形式上要一致，即单复数形式与谓语要一致。2） 意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。3） 就近原则，即谓语动词的单复形式取决于最靠近它的词语，一般来说，不可数名词用动词单数，可数名词复数用动词复数。 There is much water in the thermos.但当不可数名词前有表示数量的复数名词时，谓语动词用复数形式。 Ten thousand tons of coal were produced last year.1、 语法形式上的一致 主语为单数形式，谓语动词用单数形式；主语为复数形式，谓语动词也用复数形式。 Thenumberofstudentsinourschoolis1,700.
