英语改病句！急啊！！！

I did lost my wallet yesterday. did去掉，（一个句子不能有两个动词）
John don't like rock music. John don't like R&B (R&B表示摇滚乐更好一点吧？) 或John don't like to rock music ( like to do something)
The soup smell terrible. smell 改成smells,原因不记得了。。。
He must knows the chairman. knows改成know,must后面跟动词原形
We are going to not hold a party. not放到are后面，not放在be动词和助动词后面
The sun doesn't rise in the east. 额，east改成west吧，太阳不是从西方升起来的。。。
