As we all know, now the H1N1 flu is quite serious and spreading rapidly. However, if we take good care of ourselves, we can protect us well from it. The simple ways are like these: 1, we should keep our classrooms clean and at times open the windows to let in the fresh air. 2, We should take some exercise to buil our body healthier. 3, We seldom go to the crowded places, where there are probably more spreaders. In one word, we can win the battle against the H1N1 flu as long as we unite in one and do something to control its spreading.
