不定式短语、动词-ing形式或名词性从句作主语，谓语动词用单数形式。如：
Remember /To remember English words is not easy. 记英语单词不容易。
Who will do the job hasn’t been decided yet. 谁来做这项工作还没决定。
注：what引导主语从句时，如果其表语是复数形式，谓语动词要用复数形式。如：
What he took with him were two books. 他带去的是两本书。
不定代词one, no one, the other, another, anyone, anybody, someone, somebody, everyone, everybody, nobody, anything, something, everything, nothing, each, either 以及被each, every修饰的名词做主语，尽管有些表达复数意义，但是，它们的谓语应该用单数形式。如：
Is everybody here today? 大家都到齐了吗?
Neither (book) is good. 两本书都不好。
None knows the weight of another’s burden. 见人挑担不吃力。
注：neither, none做主语时，口语中或非正式文字中，谓语动词通常用复数，正式的书面语中用单数。如：
Are/Is neither of the teams playing this week? 这个星期两个队中有哪一个队要进行比赛?
None of them has/have been to the Great Wall. 他们中没有一个人去过长城。
不过，none作主语，其表语是单数，谓语用单数;表语是复数，谓语则用复数。
在定语从句中，当关系代词 who, which或 that做主语时，从句中的谓语动词应该与先行词保持一致。如：
The teacher who teaches us English is from England. 教我们英语的教师是英国人。
Are these the books that were bought yesterday? 这些就是昨天买的书吗?
I, who am a new teacher, will teach you English. 我，一个新教师，将教你们英语。
one of+名词复数”后面的定语从句， 谓语动词应该用复数;而“the (only) one of + 名词复数”后面的定语从句的谓语应该用单数形式。如：
He is one of the students that have passed the exam 他是通过了考试的学生之一。
He is the (only) one of the students that has passed the exam. 他就是通过考试的那个学生。
某些集体名词，如family, audience, class, club, company, crew, enemy, government, group, party, public, team等作主语时，如果作为一个整体看待，谓语动词用单数形式，如果就其中一个个成员而言，谓语动词用复单数形式。如：
My family are all fond of going to the cinema. 我全家都爱看电影。
The family is rather big, with twelve people in all. 这个家庭很大，总共有12个人。
当表示时间、距离、金额等度量的复数名词作主语，把它看作一个整体时，谓语动词一般用单数。如：
Surely 15 minutes is enough time for you to have a coffee. 你喝杯咖啡15分钟当然足够了。
但若与pass, go by, spend, waste等连用时，谓语动词用复数。如：
Six months have passed, and we still have no news of them. 六个月过去了，我们依然没有他们的消息
名词或代词+由with, together with, along with, as well as, besides, but ,except, including, in addition to, like, no less than, rather than等引起的短语”作主语时，谓语动词与前面的名词或代词的数一致。如：
