5. 动词
1） 表示动作中状态的词叫做动词。
2） 根据其在句中的功能，动词可分为四类，分别是：实义动词、系动词、助动词、情态动词。
说明：有些情况下，有些动词是兼类词。例如：
　　 We are having a meeting.　 我们正在开会。（have是实义动词。）
　　 He has gone to New York.　他已去纽约。（have是助动词。）
3） 动词根据其后是否带有宾语，可分为两类，分别是：及物动词、不及物动词，英语缩写形式分别为vt. 和vi.。
说明：同一动词有时可用作及物动词，有时可用作不及物动词。例如：
　 She can dance and sing. 她能唱歌又能跳舞。（sing在此用作不及物动词。）
　 She can sing many English songs. 她能唱好多首英文歌曲。（sing用作及物动词。）
4） 动词根据是否受主语的人称和数的限制，可分两类，分别是：限定动词、非限定动词例如：
　 She sings very well. 她唱得很好。（sing受主语she的限制，故用第三人称单数形式sings。）
　 She wants to learn English well. 她想学好英语。（to learn不受主语she的限制，没有词形变化，是非限定动词。）
