你知道英語一共有多少種時態嗎？你給英語的時態分過類嗎？我將用排列組合的方法告訴你所有的英語時態。
首先我們把英語分為 一級時態、二級時態、三級時態和四級時態。并沒有五級以上時態，為什么？很快你就會知道。
一級時態有五個
- 現在(do)
- 過去(did)
- 將來(will do)
- 完成(have done)
- 進行(be doing)
記住他們，你唯一需要記住的就是他們，接下來我將講解二級時態，我們可以用排列組合的方式將一級的兩兩結合這樣就得到了二級所有時態，這里要注意現在時加任何時態都等于其本身，所以我們舍棄掉1，將2、3、4、5兩兩結合。
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
接下來就到了三級時態，和前面一樣，我們將2、3、4、5三個三個結合
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
四級時態就是那一個了
2+3+4+5 = did + will do + have done + be doing = would have being doing
有沒有覺得變簡單了呢？有沒有幫到你的？如果能幫到那就太好了！為什么沒有把時態的中文寫出來？因為
