That's all.Thank you.

顺便问一问，“现在我们学校也出现了一例病例”怎么说

Answer 1

1.H1N1 is the most terrible epidamic that people are afraid of today

有点成分赘余，建议去掉that people are afraid of ，因为已经用了terrible，重复

2.Up till now,there are thousands of people were killed by this formidable disease,

语态有误，建议改为
Up till now,thousands of people have been killed by this formidable disease,

3.As far as i know ,pfirst we are supposed to ay attention to our daily activities

缺少“引子”话出无因，建议改为

to keep us protected from the disease,first of all,we should pay attention to our daily activities

4.second----secondly

5.那句话的翻译：by now, one infected student has been found here in our school
