我们已经看到，开门见山的开头使论文直切主题，直白明确地提出了论点。不过在讨论某些有争议性的问题时，就显得有欠缺，因为我们必须在文章的开头引出人们对要讨论的问题的不同看法，然后再表明自己的观点。下面就是专门针对争议性论文的一种句型。

　　IV.When it comes to……，some people think ／believe that……，others argue ／claim that opposite ／reverse is true.There is probably some truth in both arguments／statements，but……当说到……，有些人认为……，但另一些人则持相反的观点……。这两种观点可能都有点道理，但……。

　　本结构先用when it comes to ……引出话题，再用some……others……这个对立的结构引出了两种相反的观点，然后说There is some truth in both……表明严谨公正的态度，最后用but……很自然地引出了自己的论点。请看下面这个例子：

　　TV,a good thing or bad thing When it comes to TV,some people believe that it is extremely valuable,as it provides relaxation,entertainment and education. Others argue that it is harmful for it begins to control our lives and deprives people of time to do other activities.There is probably some truth in both sides.But we must realize that television itself is neither good or bad.It is the uses to which it is put that determines its value to society.

　　二、结尾句型

　　英语议论文多以简要总结全文或对所讨论的问题提出解决办法来结尾。总结全文时除常用到in one ／a word，generally speaking等外，没有固定模式。提出解决办法时却常使用下一句型。

　　V……take measures to do sth.例如：

　　1.We should take measures to control pollution in order to save the world.

　　2.We''''d better take effective measures to prevent students from cheating on exams.

　　3.The government decided to take strong measures against drug abuse.

　　4.Urgent measures should be taken to prevent terrorists from carrying out further attacks.
