问题：英语修改病句第一句：You'dbetteraskyourmoth 
第一句：You'd better a your mother if it fits you or not.第二句：Couldyou tell me where did he lived many years ago?第三句：She said that September 10 was Teacher's Day.第四句：John couldn't decide that shirt to buy.第五句：I think it is not going to snow tomorrow.
回答：1、if改为whether。if一般不与or not连用。
2、did去掉。where引导宾语从句，宾语从句用陈述语序。
3、was改为is。9月10日是教师节是个客观事实，用一般现在时表达。
4、that改为which。不能决定买哪一件衬衫，所以用which。
5、I don't think it is going to snow tomorrow。否定转移，主句的主语是第一人称，谓语动词是think，suppose，imagine，guess。believe，expect等等时，用否定主句的方法来否定从句。
