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.

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.

“以情动情”是教育的共同规律。教师的情感对学生来说,是导体,是火种。教师首先要善于将自己对教材的感受及情感,体验传导给学生,让学生爱读说明文。俗话说:“树倒猴群散。”如果教师自己都厌教,那么,怎么谈得上学生“学海无涯乐作舟”呢?

叶老说过,说明文“是传授知识的文字”。美国教育家布鲁纳指出:“学习的最好刺激是对所学教材的兴趣。”根据说明文具有知识性强和中学生正处于求知欲旺盛期的特点,教师只要充分利用和挖掘现成教材中的趣味因素,一定会激发和培养学生的学习兴趣的。例如第三册中,《松鼠》、《动物尾巴的功能》,文字活泼,生动有趣;《沙漠里的奇怪现象》、《北京亚运村》,有利于激发学生强烈的求知欲;《中国石拱桥》、《祖国的大豆》文情并茂,既富有知识性,又饱含强烈的爱国激情。
