如果前面的主语是第一人称或者第二人称，或者是复数形式的话，就用动词原形。
例如：
he works hard.
I/You/they work hard.
在第三人称单数时用三单，She likes apples.He wants to buy a sweater.
you,I,we,you,their,they等情况下用原形。
??单三？？ 不是三单么 ？第三人称单数。。
she he it 还有 名词 是单数的 后面的动词加 s 或es 或 去y加 ies
刀knief除外。
一般现在时 动词用原型
在he she It 后用 单三。
用原型的情况：
1在情态动词后用原形,如:can may ......
2启示句用原形
3否定句用原形
1过去时变
2第三人称单数变
当遇到单数第三人称（一个人名，he,she,it)，动词就变为单三形式。
在问句中（不论一般疑问句或特殊疑问句），在一般现在时态中I,you,we,they
