基本上每个完整的句子都有一个动词，主语的数量决定了动词的数量。下面小编告诉你英语动词后面复数和单数用法,让我们来看看！
英语动词后面复数和单数用法：

The bittersweet flavor of youth—its trials, its joys, its adventures, its challenges—is not soon forgotten.(对)
2. 一个常犯的错误：用one of .. 开头的关系从句。
比如 One of the ablest scientists who has attacked this problem. (错)

3. each, either, everyone, everybody, neither, nobody, someone之后的动词用单数形式。

4. NONE是一个特殊的单词。当它的意思是no one 或者not one的时候，其后的动词用单数。

当它的意思代表两个或者多个时，其后动词用复数。

5. 用and将两个或多个名词连接组成的主语，大多数都要用复数。
另外的情况是当两个名词组成的是一个整体时，要用单数。或者由each/every限定时。
如: Bread and butter was all she served.
Give and take is essential to a happy household.

6. 单数主语的动词依然是单数，即使将其它名词用with, as well as , in addition to, except, together with, no less than 连接。

The general's quarters are cross the river.
8. 记住一些成语或习语，因为里面有很多特殊性。
9. 动词的单复数形式，有时候要根据情况来判断。 比如你需要根据一个容器里的实际内容来判断是用单数还是复数：一盒果酱用单数;一盒弹珠用复数。
the group 作主语谓语动词用单数还是用复数的问题：
(1)group 用作集合名词，作“(小)组，群体，集团”解时，其谓语可以是单数，也可以是复数。例如：The research group is ready to start its work. 这个研究小组已准备好随时开始工作。/ The group are divided in their opinions of the matter. 小组成员在对问题的看法上意见不一致。
注：在强调其整体性时，谓语常用单数，而强调其组成的个体成员时，谓语多用复数，与 group 对应的人称代词在数上须与句中谓语保持一致。
(2)a group of (一群，一批)用于there be 引导的句子中，其谓语形式可以是复数形式，也可以是单数形式。例如：There are ( 或 is ) a group of children playing on the sports ground.操场上有一群孩子在玩耍。
注：使用复数形式多见于正式文体，而单数形式则多见于口语体。也有的语法家认为，谓语be单复数的选择取决于说话者是将主语视成一个整体，还是着重于多数个体。
