主谓遥中的靠近原则1)当there be 句型的主语是一系列事物时，谓语应与较邻近的主语保持遥。
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，谓语动词与较邻近的主语保持遥。
如果句子是由here, there引导，而主语又不止一个时，谓语通常也和较邻近的主语遥。
Either you or she is to go.
Here is a pen, a few envelops and some paper for you.
