i must call the doctor. he must call the doctor.i have a new car.
i can go with her.都是一般现在时。
i am going to telephone him. he is going to telephone him.一般将来时。
判断时态关键看动词。
一般现在时最简单,所用的动词(形式)有:动词原型和第三人称单数形式;助动词do/does;情态动词can,could,shall,should,must等等。
一般将来时标志:will,be going to
其他的还有
一般过去时:动词用过去式;助动词did;情态动词could,should等。
现在进行时:be动词(am,is,are)+动词的ing形式
过去进行时:be动词(was,were)+动词的ing形式
现在完成进行时:have/has+been+动词的ing形式
现在完成时:have/has+动词的过去分词形式
过去完成时:had+动词的过去分词形式
初中的时态就是这八种
只要把构成记下来,判断时态就一点都不困难了。

i must call the doctor.
he must call the doctor.
i have a new car.
i can go with her(一般现在时)
i am going to telephone him.
he is going to telephone him(一般将来时)
只要出现——动词原型和第三人称单数形式;助动词do/does;情态动词can,could,should,must等,都为一般现在时。
出现will(其他人称)/shall(主语为I,We),be going to即为一般将来时。
另附说明:
will与shall的书面用法如上所示;但在口语中,shall可只用于主语为I或We的疑问句中。
