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.
记叙性文章要避免平铺直叙,记流水账,如能写得波澜起伏,就能引人入胜,耐看。
俄国作家柯罗连科的写景小品《火光》通篇运用了象征手法,但从字面上看,数百字的短文,由作者的感受引发了一波三折的景物变化,黑夜泛舟,火光又明又亮,好像就在眼前,这是开头展示的基本景象;船夫不以为然,认为还远着呢,兴起一波;自己从不相信到信服,又兴起一波;由“非常遥远”到“毕竟就在前头”,重要的是“必须加劲划桨”再兴一波
“一波三折”,“波折”要入情入理,让读者产生情理之中、意料之外的感觉,方能做到引人入胜。而脱离生活,故弄玄虚的“波折”非但不能吸引读者,还会适得其反。
镜头指影视所拍摄的一系列画面。镜头剪辑用于写作,指选取一组生动的画面来表现主题。此类文章是将所写的人物按照或故事、或画面、或片段、有序地写下来,其间的每一部分都可单独成文,组合起来又是一个完整的篇章。这种又被人们称为“冰糖葫芦式”结构,由于其形式新颖,巧妙精致而受到好评。
卒章显志
在文章结尾时,用一两句话点明中心、主题的手法就叫卒章显志,也叫“篇末点题”,“志”就是指文章的主题、中心。恰当运用这种手法可以增加文章的深刻性、感染力和结构美,有“画龙点睛”的艺术效果。
