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.
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
1.自叙自改 教材中前两次作文训练都是培养记叙能力。学生对自己叙述中产生的一系列问题发现不了或者缺乏检查、修改的习惯,这就难以达到训练目的。为此,可让学生根据自己的提纲集体口述一次,再让其思考如何充实修改;然后第二次口述,这样,从书面上看不出的'问题可以在说的过程中觉察。全体学生都能对自己的初稿进行修改。这样训练,学生思想集中,思维活跃,可以大幅度提高作文效率和质量。
2.自叙众评 教材中第三、四次作文训练是要学生提炼中心,选择材料,根据中心确定详略。有的学生分析、概括能力差,从占有的材料中提炼不出明确的中心,或者确定了中心,却看不出事件中哪些材料最能体现中心,因而难以决定对材料的取舍和记叙的详略。为了解决这一问题,可以让这些拿不准主意的同学说出自己确定的中心,并叙述自己搜集的材料,让同学们帮助分析决定。由于同学之间思想文化水准、生活情趣、语言方式相近,所阐述的意见易于被接受,所提的修改意见也更具体、更富于启发性。
3.自叙众改 教材中第五、六次作文训练是“叙述结合描写”、“记叙中穿插议论”。对记叙能力的训练,前两次已经进行过。而培养描写和议论能力是本册教材中的训练难点。有些同学想描写好却因观察不细致、记忆不清或词汇贫乏等使描写缺乏生动和形象性;想议论深刻由于观点不明确,思路不开阔而敲不到点子上,发挥不了议论应有的作用。对此,让他们在短时间里自行解决问题,写出合格的文章是不现实的。可以让其本人叙述作文内容,该描写或穿插议论处,让同学们共同用口头或书面的方式描写或议论;给能力差的同学做示范,使其能从别人的思路及语言风格中悟出提高能力的路子。这样做,表面看起来有越俎代庖之嫌,但大家集思广益,解决了难题,已收到了一箭双雕之效。
