主语中有and
如果主语是and连接的两个不定式、动名词以及从句时，谓语用复数形式
e.g. Having enough sleep and doing regular exercises are benefiticial to your health.
当主语由and连接，表示同一人、同一物、同一事或者同一概念时，谓语动词用单数，此时and连接的两个词前只有一个定冠词
e.g. The composer and singer was well recieved by the audience.
由and连接的两个或更多的主语之前有each、every、many a(n),no时，谓语动词用单数
e.g. Each book and (each) paper is found in its place.
主语中有every,each,everyone等,谓语通常用单数
each, every, each and every, either, neither, one ,another, little, a little和much做主语或修饰主语时，谓语通常用单数

e.g.Each of us has a tape-recorder.我们每个人都有一台录音机。
everyone, everybody, everything, anyone, anybody, anything, someone, somebody, something, no one, nobody, nothing作主语时，用单数动词

none, some, any, more, all等代词作主语时，动词的单复数由其指代的词的单复数决定
e.g.All is right.所有的都对。 All are present.全都到齐了。
all, none, most, majority, part, enough, some, one half, the rest, the remainder of ...短语，或者more than..作主语时，谓语动词的单复数形式通常由所修饰的名词、代词的数决定
e.g.More than one person is going to lose his job. More than 300 people are going to lose his job.

e.g. Two thousand tons of coal were produced last year.
当中心词是度量、距离、时间、价格等复数名词时，谓语采用单数形式
e.g.Two miles is a short distance.
在定语从句中，若引导词在从句中充当主语，谓语的数要和先行词一致
e.g.There is somebody who wants to talk with you.
当主语后面跟有including, with, together with, along with, like , in addition to, as well as, rather than, as much as, more than,no less than等连接的短语时，谓语动词不受这些词组的影响，与前面的主语一致
e.g. He as well as I wants to go boating. An expert, together with some assistants, was sent to help in this work.
采用就近原则：or, either..or, neither..nor, not only..but also连接两个以上的主语时；当句子由here，there引导，且主语不止一个时
e.g.Either you or she is go to.你或她要去。 Neither he nor they were late last time.他上次没有迟到，他们也没有迟到。 Here is a pen, a few enevlops and some paper for you. There is a pen, a knife and several books on the desk.
"the+形容词"作主语，代表单数名词时用单数动词;如果意义指一类人，则应视为复数，谓语动词用复数。
e.g. In many stories, the good are well rewarded and the bad are doomed to unfortunate.
who作主语时，即使被问者是复数，通常也是用单数疑问代词；which作主语时，其动词是单数还是复数根据which所指的单复数而定
e.g.Who wants to come with me? -We do.
