america.发现美洲后烟草被引入到欧洲。my parents smoke and they have both tried to give up many times.我父母都吸烟，他们试图戒烟很多次了。第二步：从正方辩论。给出实例，证明论点。例如： firstly，it costs a lot of money to treat smokers who get diseases，such as heart disease or lung cancer.首先，你要花一大笔钱来治疗吸烟引起的疾病，诸如心脏病和肺癌。secondly，some people are in favour of the idea of doing.其次，有些人赞成这个主意。they point out the fact that.他们指出这一事实第三步：从反方辩论。给出实例，证明论点。例如：on the other hand，if they banned smoking，the government would lose a lot of money from taxes on cigarettes.另一方面，如果他们禁止吸烟，政府会损失一大笔来自香烟的税收。however，other people stand on a different ground.然而，另一些人站在不同的立场上they consider it.to do.他们认为去做第四步：发表自己的观点。常用句型有：in my opinion，.在我看来，after things are considered，i believe that.从各个方面考虑，我认为写作时应注意：1议论文的一般结构方式是：提出问题、分析问题、解决问题。2英语议论文时态较为统一，多用现在时；强调语言表达的客观性；尽可能指明信息来源等。3常用虚拟语气，让步状语从句和情态动词can，could，may，might，would，should等。4常用although，though，in spite of，despite，however，on the other hand，also，moreover，finally等过渡词。议论文英语表达经典句：1first/firstly，second/secondly，then，next，after that，afterwards，last/lastly/finally.2some people believe/argue/recognize/think that.3everyone knows that.4it seems obvious to me that.5people hold different views/ideas about.6as for me，i agree to the former/latter idea.7above all，.【写作演练】以“smoking and cigarettes”为题目写一篇议论文。正方：1.抽烟能够提神和娱乐。2售烟量降低，种植量降低，政府收入降低。反方：1.抽烟者多为年轻人，甚至中学生也抽烟，在中国吸烟者占总人口的45%；2.抽烟的害处：有害健康，可导致多种疾病，浪费，甚至可能引起火灾；3.劝告抽烟者戒烟，不抽烟者不要学抽烟。【经典范文】smoking and cigarettesif you look in some public places，you will see that most smokers are young people，even middle school students.it is said that in china the number of smokers is about 45 percent of the population.why do so many people smoke？some think that smoking is a pleasure.some believe that they can refresh themselves by smoking.besides，if no one smokes，the farmers will not plant tobacco and the government will reduce its income.on the other hand，in fact，smoking is a bad habit.it does great harm to peoples health.studies of smoking show that many kinds of diseases are related to smoking.moreover，smoking itself is a waste for it costs one so much money.besides，many fires are often caused by careless smokers.in my opinion，as a student，you should not start smoking.if you are tired，you can do exercises to refresh yourself.although you are curious about smoking，it wont do good to your health.and those who have already addicted should try their utmost to quit the bad habit.we all know that nowadays more and more people all over the world have begun to give up smoking.【点评】1本文分为四段，步骤齐全，层次分明，论点鲜明。2运用了on the other hand，besides，in my opinion等词语，过渡自然。3运用了if条件状语从句，使得文章说理性强。假如你是某英文报的小记者，针对当前流行“偷菜”网络游戏这一现象进行了采访，请就被采访者的看法写一篇短文，内容要点如下：观点一：1.体验田园生活，享受乐趣2忘记烦恼，减轻压力3.增长知识观点二：1.沉迷网络，影响健康2耽误学习、工作3可能影响孩子的价值观注意：1.词数：120左右。2开头已写好，不计入总词数。3
