How to prevent the H7N9?
As is well known,the A flu is spreading throught our country. However, if we negnect it, the deadly H7N9 may cause more infectors,or even more deaths. So what is the most important is that we should take some effective measures to prevent it.They can be listed as follows.
Firstly,it is necessary for you to realize the Avian flu can be prevented if you develop good living habits. For example,you shouldn’t forget to wash your hands before meals.Besides,don’t spit everywhere and try to cover your mouth or nose with paper or hankerchiefs when you have to cough or sneeze.What’s more, remember to wear the mouth-cover if you have to go to the public places, such as the crowded cinemas,supermarkets, buses,where the A flu may spread easily.
Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
Last but not the least, if you are unlucky to be infected with the slight flu cold, try to stay at home,and take some medicine. Do pay attention to your daily body temperature. If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.
Only by doing like this can you prevent or defeat the A flu in the end.

我利用寒假，制作了一个实验装置来验证吸烟对肺部的影响：
设计目标：
通过演示试验了解吸烟对身体的严重危害性。从而引导同学们开展“拒绝吸烟”、“劝戒行动”进行创新活动设计。在活动中知道自觉拒绝香烟，维护自己的权益、维护环境。
装置材料：
一个透明的瓶子矿泉水瓶（含盖子）、香烟、橡皮膜、面巾纸等
装置制作：
取矿泉水瓶盖，在瓶盖上钻一个孔，使一支香烟能够正好卡住，将矿泉水瓶去底，在上面蒙一层橡皮膜用胶水粘牢，松紧要适度，沿瓶盖内部边缘粘一层面巾纸，盖上瓶盖，这样一个简易的实验装置就制作完成了。
实验操作过程：
将一支香烟点燃，插在瓶盖事先打好的孔上，点燃部分向上，模拟人口吸烟过程，来回拉动矿泉水底部的橡皮膜，模拟人的呼吸，这时会发现有烟进入瓶中，而渐渐的会使面巾纸变成黄色，产生很多烟油附在纸巾上（面巾纸模拟人体肺部肺泡），而如果长时间拉动橡皮膜的话瓶子内就会形成一层尘垢。（瓶子模拟人体肺部）。
实验总结：
本实验通过运用材料，模拟了人体吸烟对人体危害的.过程，橡皮膜的拉动，模拟人不断呼吸、面巾纸模拟人体肺部肺泡、瓶子模拟人体肺部，通过一系列实验最终验证了吸烟有害健康。并且说明了吸烟对人体肺部的影响，从而告诫人们切勿吸烟本实验装置材料完全取材于生活，都是一些身边的物品，并且切实地说明了吸烟有害健康这一主题，制作简单，容易操作，实验效果明显使大家直观的了解实验结果，使大家明白吸烟几乎损害人体全部重要器官。对于这一点很多人不以为然，因为这需要时间证明，但我们绝不做此实验的试验品！能够使同学们通过自己动手做实验明白烟对人体的危害，从而达到使同学们远离香烟，拒绝吸烟，永于向香烟说“不！”还可以激发同学们的学习兴趣，促使同学们不断创新，不断努力，向着科学的世界冲！冲！冲！为了我们自己的健康，我们呼吁，全体同学都要自觉地远离香烟，并劝说吸烟的亲友尽量戒烟。毕竟，香烟对我们有害无益；毕竟，没有烟雾的空气会更加清新，没有烟草的生命会更加绚烂！同学们，让我们行动起来，从现在做起，从自我做起，严格控烟，向更多的人宣传吸烟有害健康的公益知识，呼吁全社会都珍惜自己和他人的生命，自觉控烟，坚决拒绝“二手烟”。使我们的天空更加湛蓝！使我们的明天更加辉煌！
