当一个句子有两个主语时，而它们又是用 neither…or, either…or, not only … also连接时谓语动词应与邻近的主语相一致。如： Either Ann or Jane is from New Zealand. Nither he nor I finished the expriment. 由there或here引起的句子，主语又不止一个时谓语动词通常和邻近的那个主语相一致。如： There is a lamp,two books and three pens on the desk. Here are some envelopes and paper for you.
