一般现在时

I do my homework at 7.我平时都在7点写作业。

don't和didn't都表示否定，如何区分用法呢，don't表示一般现在时，表示平时也不做，理解成不做这件事。didn't是一般过去时，表示过去没有做，现在做不做不一定，所以可以理解成没做这件事。

I don't eat fish 我不吃鱼。

I didn't eat fiash。我没吃鱼。

I don't drink beer 我不喝酒。

I didn't drink beer 我没喝酒。

I don't go to school 我不上学

I didn't go to school 我没上学

I did my homework at 7.我7点写完的作业。

I will do my homework at 7.我将要在7点写作业。

I am doing my homework 我正在写作业。

I was doing my homework at 7 yesterday.我昨天7点的时候正在写作业。

I hava done my homework.我已经写完作业了。

I had done my homework before yesterday。我昨天之前就已经写完作业了。

I said I would do my homework。我说我将会写作业的。
