问题描述：
英语过去式,我不得不做作业
答
一定要过去式吗？
那就只能是：
I had to do my homework
不然的话，可以是：
I must do my homework
答
I had to do my homework。
I had to do the homework。
这两个一般过去式
I had had to do my homework。
这个是过去完成式
答
I had to do my homework.
答
应该是
I had have to do my homework.
第一个had表过去时间，
第二个have是跟to连接在一起不可分开的，表示意思必须。
