英语句子的一些问题
1,when my car was stopped by the police i was sure i had broken some traffic rule or other without realizing it.then i heard one of them say i _______the law by not wearing a seat belt.(vilate 的正确形式）
2,why didn't you call a taxi _____________________________(照我对你说的那样）（用as的定语从句）
3__________________the morning after having read our first assignment,she asked me the first question(填一个介词）
可以说说你们的看法吗?
我不能肯定答案没错 但答案是这样的 所以我才不明
1 was violating
2 as I told you to
3 on （小狼GOGO说对了）
但具体答案为什么这样我想知道其中的语法

答案

had vilated
as I had told you 前面有did必须用过去完成时
on the morning after having read our first assignment这才是句子成分,要用on（in the morning后面不接成分采用in 的）
