Answer 1

1.Why do you look at the driver so angry （look at 是一个短语,不能被拆开）
2.The fire has lasted for two hours.（since后面一般是跟一个点的时间,自从.比如since two hours before.)
3.They did't think it was terrible to use the polluted water.( it是形式主语,不能用that）
4.I have already told you that washing hands may keep you healthy.(一般already跟完成时,并且为了时态一致,最好也用完成时）
5.Could you please tell us when you will visit the World Expo?(宾语从句中,主谓次序跟陈述句一样）
6.-Would you mind removing the snow here?-No.I'm glad to do it.(前面问的是：是否介意,所以回答要先否定：不介意）
