免费英语学习之主谓一致中的靠近原则

　　主谓一致中的凑近准则的免费英语学习知识点：

　　  
1）当there be 句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。
免费英语学习例句：There is a pen, a knife and several books on the desk..
There are twenty boy-students and twenty-three girl-students in the class.

2）当either… or… 与neither… nor，　连接两个主语时，谓语动词与最邻近的主语坚持一致。 免费英语学习注意如果句子是由here, there引导，而主语又不止一个时，谓语通常也跟最附近的主语一致。

　　Either you or she is to go.
Here is a pen, a few envelops and some paper for you.
