1. 就近型:由or, either…or, neither…or, not… but…, not only…but also等连接的并列成分作主语时,其谓语通常要与靠近的主语保持一致。如:
Neither you nor he is tired. 你和他都没累。
Not you but I am to blame. 不是你的错而是我的错。
Either my father or my brothers are coming. 不是我父亲就是我兄弟要来。
2. 就远型:由as well as, as much as, rather than, more than, no less than 等连接的并列成分作主语,其谓语通常与前面一个主语保持一致。如:
The son, as well as his parents, wants to go there. 不但儿子想去那儿,而且他的父母也想去。
3. 复数型:由and和both……and连接的并列成分作主语,其谓语总是用复数。如:
(Both) New York and London have traffic problems. 纽约和伦敦都存在交通问题。
注:当由and连接的两个并列主语受each, every, no的修饰时,其谓语用单数。另外,当and连接的两个的词语指同一个人或事物时,其谓语也要用单数。如:
Every man and woman wants to join it. 每个男女都想加入它.
