一、原因段的写法：核心
第一句话：从理论伦理等方面讲原因。
数据：In accordance with the most updated statistics conducted by Newsweek（报纸、大学、著名杂志）, a famous newspaper conerned with public health in America, smoking is the biggest killer today for us（废话插入语）, causing over 3million lives a year.
理论： Based on the most widely accepted theory concerning public health and smoking by professor Alexsandra Coffman(名字必须牛逼), a leading expert in the research of health, smoking is causing huge disaster for human beings today.
伦理：【respecting the old was,is and will be a highly valued tradition for everyone（尊重老人）蒙太奇写法】
【 respecting the old was,is and will be a highly valued tradition for everyone，old or young, rich or poor,man or woman（尊重老人）升级版】｛可以写抽烟等，用途广泛｝
基础差的模式：（救命稻草） 【Miss gao, a teacher who taught me english when i was in school; a friend who helped me a lot when i was in trouble; a lady who is always nice to her students, died now.】（红色为主干）
第二句话 ：从实践中找原因。（好处/坏处）｛可以选两个写，写了这种抽象句子，要加实际内容，具体化，不嫩该台空洞｝
主题词： environment ；physical and mental health ；economic development ；public health；education ；cultural
heritage ；social harmony ；career development.
