1. 代词作主语
1)all, most, none, some等代词作主语，要遵循意义一致的原则，即：其谓语动词的单、复数形式要根据他们所替代的词的含义来确定。
如：All of my classmates work hard.我们班所有同学都很用功。
All of the water is gone.所有的水都用光了。
2)由代词each, every one, no one, either, neither，以及复合不定代词anything, something等作主语，谓语都用单数。
如：Each of the twenty guests was given a present.给20位客人每人赠送一份礼物。
Someone wants to see you.有人要见你。
3)表示数量的不定代词much, little作主语，谓语动词使用单数;而many, few作主语，谓语动词用复数。
如：Much of our food comes from plants.我们的许多食物来自植物。
Only the few are likely to enjoy this music.只有那少数几个人可能喜欢这音乐。
2. 有连接词连接的名词或代词作主语
1)用both…and或and连接的并列主语，谓语动词用复数
如：Both the secretary and manager have agreed to be present.书记和经理都同意出席。
注：但是，由and连接的并列主语如果指的是一个人、同一事物或同一概念，谓语用单数。这时后面的可数名词没有冠词。
如：The poet and writer has come.那位诗人兼作家来了。
2)当名词或代词后面是with, as well as, along with, together with, but, except, in addition to, rather than等连词作主语，谓语动词一般和前一名词或代词的人称和数一致。
如：Dr. Green, together with his wife and two sons, has just left and will return at four o’clock.格林博士及其夫人和两个儿子一起刚刚离开，将于4点回来。
3)由or, either…or, neither…nor, not only…but also等连接的名词或代词作主语，谓语动词要符合就近一致的原则，即要与邻近的主语一致。
如: Either the principal or his assistants are to attend the meeting. 要么校长要么他的助手们得去参加会议。
3. 数词、量词作主语
1)分数或百分数+of+名词构成短语作主语，谓语形式是用单数还是复数取决于他们表示的意义。
用法类似的结构还有half of, a lot of, plenty of, a large quantity of, the rest of等
如：Half of the students have read the novel.一半学生读过这本小说。
Half of the food is unfit to eat. 一半的事物不能吃了。
There is plenty of wine in the bottle.瓶里还有不少的酒。
There are plenty of books on the shelf.书架中有很多书。
2)the number of+可数名词， the amount of+不可数名词， the quantity of+可数名词或不可数名词的短语作主语，谓语用单数。
如：The number of the pages in this book is 500.这本书的页码是500页。
The quantity of books in the library is amazing.图书馆书的数量是令人惊讶的。
