1.主謂一致中的靠近原則
1）當there be 句型的主語是一系列事物時，謂語應與最鄰近的主語保持一致。
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）當either… or… 與neither… nor，連線兩個主語時，謂語動詞與最鄰近的主語保持一致。如果句子是由here, there引導，而主語又不止一個時，謂語通常也和最鄰近的主語一致。
Either you or she is to go.
Here is a pen, a few envelops and some paper for you.
2.謂語動詞與前面的.主語一致
當主語後面跟有with, together with, like, except, but, no less than, as well as 等詞引起的短語時，謂語動詞與前面的主語一致。
The teacher together with some students is visiting the factory.
He as well as I wants to go boating
