文档介绍：独创时态顺口溜:英语时态口诀顺口溜
①常常和习惯，事实和真理，全部是通常现在时；
Be用am/is/are, Do用原形和单三， 过去和未来，界限很清楚，ago表过去，in后段时间，代表未来时！
②通常过去不可回，Be是was/were; Do要变did ；
③通常未来未到来，will来帮助，还有be going to，未来助动词，两个全部要记！
④进行时，正发生。
be 后接doing，组成进行时。
现在进行时，此时此刻正发生，be变am/is/are，然后必需接doing， 过去进行时，过去某刻正发生，be变was/were，然后必需接doing 切记：be和doing不分家，丢掉be动词，构不成进行。
现在完成时，跨越两个轴，过去和现在，相互在影响， have/has来，后面动词要变done for加段时间，since点时间，全部是标志词，题眼是关键,若是for后段时间，动词延续莫忘记！
备注：时态题做题思绪和步骤 第一：依据语境情况加上标志词推断用什么时态；
第二：对接对应的时态结构进行选择。
