主谓一致逻辑意义一致原则一.主谓一致的种类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。
如：The nu mber of the stude nts prese nt is 200.Jane and Mary look alike.2 •意义上一致1) 主语形式虽为单数，但意义为复数，谓语动词用复数。
如：The crowd were shouti ng.单数形式代表复数内容的词有：people, , cattle等。
2) 主语形式为复数，而意义上却是单数，谓语动词用单数。
女口：The news was so surpris ing.形复意单的单词有news和一些以ics结尾的学科名称，如physics，politics, econo mics 等。
3. 就近原则即谓语动词的单、复数形式取决于最靠近它的词语。
如用连词or, either -or, neither…not,ot only…butalso等连接的并列主语，如果一个是单数，一个是复数，谓语动词与靠近它的主语一致。
如：Either your stude nts or Mr. Wang knows this.二、逻辑意义一致原则逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时主语形式为单数，但意义为复数；有时形式为复数，但意义为单数)。
