第一行改a piece of news which was
第二行改who was death.
They were destroied 应该把were去掉
第四行this week's football match were put off 应把were改was
the problem was slove应把was去掉,slove改成sloved
第六行they were child应该改成children吧
第七行On the contrary中contrary是不是拼写错误?
第八行building 应该加s
第九行This is the important reason 中important应该用最高级吧
希望有用!
