英语中不同时间和方式发生的动作或状态要用谓语动词的不同形式来表示，这种表示动作或状态发生时间和方式的动词形式称作动词时态。时间主要有四个主要部分，即现在、过去、将来和过去将来。动作方面也有四种，即一般、完成、进行和完成进行。把这些时间和动作方面结合在一起就构成16种动词时态。（以play为例）具体表述如下：1、一般现在时（We play)；2、一般过去时(We palyed)；3、一般将来时(We will play)；4、一般过去将来时(We would play)；5、现在进行时(We are playing)；6、过去进行时(We were playing)；7、将来进行时(We will be playing)；8、过去将来进行时(We would be playing)；9、现在完成时(We have played)；10、过去完成时(We had played)；11、将来完成时(We will have played)；12、过去将来完成时(We would have played)；13、现在完成进行时(We have been playing)；14、过去完成进行时(We had been playing)；15、将来完成进行时(We will have been playing)；16、过去将来完成进行时(We would have been playing)。其实是英语动词的时和体.时有现在,过去,将来和过去将来;体有一般,完成,进行和完成进行.而态有2种,即主动和被动.
