4道初二的汉译英的问题

1.
不知道第一句的意思是什么?
是“我们去你家不方便（有问题)”
-It is not convient for us to go to your home.
还是“我们有问题,所以要去你家问你”
-We are going to your home for we have some questions.
【本来“去你家”可以用drop in at your home来表达的,但是考虑到你是初二的,应该还没学过】
2.
---When did you lose your dog?
---3 days ago.
3.
This traffic accident happened 2 years ago when this road hadn't been built.
4.
He gave me some advise before I did it.
[初二的翻译这样应该可以了,其他更进一层的表达就不赘述了,希望有用吧]
