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.
地球是我们人类的家园,也是人类的母亲。我们依赖它,探索它。这个蔚蓝色的星球多么美丽,但我们要知道:地球只有一个!
我为周围环境的恶化而感到心痛,我想:作为未来接班人的青少年,如果不了解环境问题的严重性,无视有关环境保护的法律法规,不去增强环境保护意识,我们的生命将毁在自己的手中,老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境,保护我们这个赖以生存的家园,做一个保护环境的卫士。
如果我们破坏环境,浪费水资源,生物会灭绝,人类会渴死,地球会变成沙漠。水是人类的好朋友。我们从小就被大人教育,节约用水,这个道理我们谁都可以倒背如流,但却没有人真正的重视过。
然而,近几年来,地球的环境却越来越恶劣:全球性气候变暖,飓风、暴雨等灾害性天气频繁出现,“非典”、禽流感等传染性疾病时有发生,给人类的生活和工作带来严重威胁和许多不便。这些都是人们不断地“伤害”地球的结果。大片的森林被砍伐,碧绿的青山被挖掘,美丽的草原成荒漠,清澈的河水成浊流。树林少了,青山秃了,草原荒了,清水黑了,使人们生存的环境变坏,呼吸的空气变差,生活的环境被许多有害的东西所“侵占”,病毒就趁机钻进人们的体内,我们人类就会患上一些可怕的疾病。
俗语说得好:“前人栽树,后人乘凉”,前人给了我们大片大片的森林,绿地,我们留给后人的是什么?是光秃秃的荒漠,还是茂密的树林,你肯定选择的是茂密的树林。那还有什么犹豫的,让我们大家一起自觉保护环境,自觉爱护环境,自觉绿化环境,改善我们的生活环境,创造美好的未来!
我们的地球已经进入了病入膏肓的状态。后知后觉的地球人,直至近几年才大力鼓吹环保运动,但却不见有任何的改善,正所谓“江山易改本性难移”,或许我们需再花上一个世纪,甚至几十个世纪的时间才能有效的拯救地球吧。
如果就连身为地球人的我们都不珍惜、爱护地球,那这工作将由谁来做呢?环保工作其实并不难,只要全世界的人一人捡一份垃圾,那么这地球就会干净多了!
保护环境,是我们每个社会公民的义务,我们要自觉的行动,并坚持在随时随地保护我们周围的环境,保护环境,就是在保护人类生存的最宝贵的地方。
我希望大家都来保护环境,让大家知道,破坏自然环境,就等于自毁家园。让全世界少年儿童,都能自觉保护环境,保护生态自然环境,使人类生活变得更加美好,更加幸福。
A tiger is a kind of catamount animal. It looks like a cat, but much bigger than a cat. A tiger is very ferocious and it eats mainly meat. It has yellow and black streaks all over its body and it looks very beautiful. Its tail is long and strong and it can hit its quarry dying.
Tigers live in the thick forests and small animals in the forests are tigers' food.
During the past years, many forests have been cut down and the living conditions of the tigers are becoming worse and worse. There are fewer tigers left in the world now. Tigers are the animals of the world, and they should have their own living spaces. We must do our best to protect the tigers and their living environment.
Tiger is one of the most valueable animals to human beings today. It is somehow like a cat, but much bigger than it. It lives in the forest, and feeds on small animals.
Nowadays, the number of the wild tiger is becoming small and small. Maybe there will be no tiger any more if people continue cutting the trees, destorying the living environment or hunt the tiger just for the skin. We must stop all these mistakes. We should protect them, because the world without tiger is not a completed one.

如今大家都提倡环保,还想出了许多的环保标语:保护环境就是保护我们自己;破坏环境,就是破坏我们赖以生存的家园;土壤不能再生,防止土壤污染和沙化,减少水土流失;环境与人类共存,资源开发与环境保护协调;保护水环境,节约水资源;树立大环境意识,保护生态环境;使用较少塑料袋,是友好的对我们的环境……我们的地球只有一个,需要我们一起来保护。
而塑料袋是我们最大的问题,我们在生活中有许多的地方需要它,但它会造成白色污染,让空气不再那样清新,让我们生活在细菌的王国里。国务院办公厅发下通知:6月1日起全国禁止免费提供塑料购物袋,要自己掏钱买。所以政府和公众都提倡用环保袋代替塑料袋。
那环保袋有什么好处呢?它不但可以反复利用,而且对生态环境有益。在环保袋的设计上,很多环保热心人士纷纷提供杭州美景的摄影作品,想采用到环保袋上,最终荷花宝宝成为环保袋上的图案。荷花宝宝是20xx年快报摄影记者夏阳拍的。在他的博客里,网友、读者纷纷为荷花宝宝留言:网友“天堂有约”说,“这真是一朵幸福的荷花,我喜欢这个城市,好有人情味。”徐君敏选择将荷花宝宝的图案放满整个袋子,不留下任何空白。让在繁忙中的人们走进自然,亲近自然。环保袋两面分别截取了荷花宝宝生长的第2天和第4天的瞬间,短短两天之间,它又有了新的变化。这是为了让人们知道自然界的生物都有其成长规律,用荷花宝宝的成长过程,是在提醒人们尊重自然规律,不要为了自己的利益去破坏自然平衡。
人们为了自己的方便发明了塑料袋,而塑料袋在自然环境中要数百年才能降解,不加节制地滥用,已经导致了一系列环境问题。所以我们要尽自己一切努力改正以前滥用塑料袋的习惯,呼吁大家使用环保袋,节约资源。
