Period Three　Grammar，Speaking & Writing

英语句子的主语和谓语要一致。常见的有下列几种情况：

一、语法结构的一致

1.由连词and或both...and...连接的两个并列成分作主语，其谓语动词一般用复数。

汤姆和他弟弟都通过了考试。

注意：(1)当and连接的两个词或词组表达的是同一个人、物或概念时，谓语动词用单数。如果这两个词都是名词，则第二个名词前不用冠词。

(2)主语后有with，together with，like，but，as well as，except，including，rather than，besides等引导的词或短语时，谓语动词要和最前面的主语保持一致。

那位农民作家正在会议室里发表演讲。

The teacher together with some students is visiting the factory.

老师带着一些学生正在参观工厂。

2.两个并列的名词前有each，every，no，many a等修饰时，谓语动词一般用单数。

每个学生和老师都发了一张票。

所有人都在工作。

Many a desk and many a bench is to be taken out of the hall.许多课桌和凳子将被搬出大厅。

3.在正式的文体中，由not only...but also...，neither...nor，either...or，or等连接两个并列主语时，其谓语动词与其靠近的主语保持一致。there be句式也是如此。
