　　三、主谓一致

　　主谓一致是指一个句子的主语和谓语动词在人称和数等方面要保持一致。主谓一致一般要遵循三个原则：语法一致原则、意义一致原则及就近一致原则。

　　(一)语法一致原则

　　主语和谓语通常是从语法形式上取得一致，即主语是单数形式，谓语动词也采用单数形式；主语是复数形式，谓语动词也采用复数形式。

　　1．由and连接的两个名词作主语，表示不同的人或事，谓语动词用复数。

　　What he said and what he did have greatly encouraged the other students.

　　他的话语和行为极大地鼓舞了其他学生。

　　2．and连接的两个名词指同一个人或物时，谓语动词用单数。

　　两个单数名词并列用and连接，表示一个概念或是不可分割的整体作主语时，谓语动词也用单数。常见的此类短语有war and peace, iron and steel, a needle and thread, bread and butter, a horse and cart等。

　　Egg and rice is her usual breakfast.

　　早餐她常吃蛋炒饭。

　　All work and no play makes Jack a dull boy.

　　只工作，不玩耍，聪明的孩子也会变傻。

　　Knife and fork is used to eat western food.

　　刀叉用于吃西餐。

　　To try and fail is better than not to try at all.

　　尝试而失败比不尝试好。

　　The teacher and writer is her friend.

　　那位老师兼作家是她的朋友。

　　3．由no ...and no ..., each ...and each ..., every ...and every ..., many a ...and many a ..., one and a half ...等构成复合主语时，谓语动词用单数。

　　No time and no money is wasted in the whole course.

　　在整个过程中没有浪费一点时间和金钱。

　　Every boy and every girl has the right to get education.

　　每一个男孩和女孩都有权利接受教育。

　　4．主语后面带有as well as, rather than, like, but, except, besides, with, together with, along with, including, in addition to, as much as, more than等词连接的名词时，根据语法一致的原则，谓语动词根据这些词前的主语来确定动词的形式。
