Good morning, everybody!
As we all know, during the last few months, H1N1 flu has been spreading quickly across our country．An increasing number of cases are being reported．As far as our school is concerned, about 20% of the students have been affected．So immediate action should be taken to fight against the disease．
The best way for us to prevent the flu is to wash our hands properly, and always keep the air fresh by opening our windows frequently．At the same time, we should do more exercise to build up our bodies．Besides, we had better stay away from crowded places．And if we have to, wearing masks is necessary．
As long as we have the right way to prevent H1N1, I think it will not be so scary．I would like to call on everyone to fight against the flu and prevent H1N1 from spreading．
Thank you!
