你知道英语一共有多少种时态吗？你给英语的时态分过类吗？我将用排列组合的方法告诉你所有的英语时态。
首先我们把英语分为 一级时态、二级时态、三级时态和四级时态。并没有五级以上时态，为什么？很快你就会知道。
一级时态有五个
- 现在(do)
- 过去(did)
- 将来(will do)
- 完成(have done)
- 进行(be doing)
记住他们，你唯一需要记住的就是他们，接下来我将讲解二级时态，我们可以用排列组合的方式将一级的两两结合这样就得到了二级所有时态，这里要注意现在时加任何时态都等于其本身，所以我们舍弃掉1，将2、3、4、5两两结合。
2+3 = did + will do = would do
2+4 = did + have done = had done
2+5 = did + be doing = was doing
3+4 = will do + have done = will have done
3+5 = will do + be doing = will be doing
4+5 = have done + be doing = have been doing
接下来就到了三级时态，和前面一样，我们将2、3、4、5三个三个结合
2+3+4 = did + will do + have done = would have done
2+3+5 = did + will do + be doing = would be doing
2+4+5 = did + have done + be doing = had been doing
3+4+5 = will do + have done + be doing = will have being doing
四级时态就是那一个了
2+3+4+5 = did + will do + have done + be doing = would have being doing
有没有觉得变简单了呢？有没有帮到你的？如果能帮到那就太好了！为什么没有把时态的中文写出来？因为
