以“我”为例说明英语各种最基本的时态：
I go to school every day.（一般现在时）
I went to school yesterday.（一般过去时）
I am going to school now.（现在进行时）
I was going to school then.（过去进行时）
I will go to school tomorrow.（一般讲来时）
I would go to school.（过去讲来时）
I have gone to school.（现在完成时）
I had gone to school.（过去完成时）
当然还会有另外一些时态的组合。建议你买一本语法书来看看。希望能帮到你。
