八大时态速记口诀
一、一般现在时
【口诀】一般现在表经常；时间状语记心上；主从复合不寻常，主将从现不能忘。
【诠释】1.一般现在时表示经常发生的动作或存在的状态；2.常见的时间状语有every day/month/year，often，usually，always等；3.在条件状语从句或时间状语从句中，若主句为将来时态，则从句要用一般现在时表将来。
二、一般过去时
【口诀】过去动作常发生，上下文中找情景；标志词语记心中，last、ago最常用。
【诠释】1.一般过去时表示过去发生的动作，多有上下文情景；2.常见的时间状语有last month/year，two/three days ago，yesterday，the day before yesterday等。
三、一般将来时
【口诀】一般将来将发生；两种结构要牢记；位移动词特殊性，将来要用be doing。
【诠释】1.一般将来时表示将来某段时间要发生的动作或进行的状态；2.一般将来时有两种结构：一是will+动词原形（否形式为won’t+动词原形）；二是be going to+动词原形（多指经过计划或安排之后发生的事情）；3.位移动词come，go，leave等用现在进行时表将来。
四、现在进行时
【口诀】现在进行be doing；now、look、listen表正进行；还要兼顾前后的语境。
【诠释】1.现在进行时的结构为be+动词现在分词；2.句中若出现时间状语now和警示性的提示语look或listen，则要用现在进行时；3.另外，有时需要根据上下文语境判断是否用现在进行时。
五、过去进行时
【口诀】过去动作正进行；运用之时有情景；和when，while总是不分离。
【诠释】1.过去进行时表示过去正在发生的动作或存在的状态；2.过去进行时的结构为was/were+doing；3.过去进行时常出现在有上下文情景的句子或when、while引导的时间状语从句中。
六、现在完成时
【口诀】过去发生的动作，导致现在的结果；already、ever、never标志多；短暂动词要斟酌，变成延续才正确。
【诠释】1.现在完成时结构为have/has+done，表示在过去某个时刻发生的动作对现在的影响或结果；2.标志词有already、just、ever、never、yet等，标志短语有“since+过去时间”和“for+一段时间”；3.短暂性动词不能喝时间段连用，但可以转换形式，如leave变换为be away，become变换为be，buy变换为have等。
七、过去完成时
【口诀】过去完成had done；“过去的过去”不能忘。
【诠释】1.过去完成时结构为had done；2.过去完成时表示到过去某时为止已经发生或完成的动作，即“过去的过去”。
八、过去将来时
【口诀】过去将来时，多在宾语从句里，常是一般将来的变形；will改为would加原形，be going to只变be就行。
【诠释】过去将来时常出现在宾语从句中，当主句的谓语是过去时态时，一般将来时时态后退就构成了过去将来时。
