英语过去式的问题
我英语不大好
例句1n she asked me if she could copy my homework
为什么copy不要变过去式 此时could是表示过去是吗
例句2 i asked her why she wanted to do that
为什么此时wandt要加ed
例句3 i said it would start a bad habit and that she should do her own work
此时would是过去式吗 start 和do为什么又不要变
如果有更多牵涉到的知识请告诉我
例句1是when开头 打错了

例句1是when开头 打错了
1.could 是情态动词 can 的过去式,情态动词后面要用动词原形,所以copy 不需要变化
2.句子的时态要一致,这一个宾语从句,前面asked 是过去时态,所以want也过去时态wanted
3.would + 动词原形是：过去将来时
should + 动词原形：应为should 是情态动词,所以后面用动词原形
