　　coin has two sides，……has its disadvantages.

　　(本例將利弊分開講，轉折過渡自然。just as every coin has two sides也很值得背誦。)

　　1.Computers play an important role in science and technology.

　　2.Computers play a more and more important role in our life.

　　本結構看似固定，實則富于變化，只要記住with有“隨著”的意思，相信大家可以根據實際的需要造出更多的句子。

　　我們已經看到，開門見山的開頭使論文直切主題，直白明確地提出了論點。不過在討論某些有爭議性的問題時，就顯得有欠缺，因為我們必須在文章的開頭引出人們對要討論的問題的不同看法，然后再表明自己的觀點。下面就是專門針對爭議性論文的一種句型。

　　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……當說到……，有些人認為……，但另一些人則持相反的觀點……。這兩種觀點可能都有點道理，但……。

　　本結構先用when it comes to ……引出話題，再用some……others

　　……這個對立的結構引出了兩種相反的觀點，然后說There is some truth in

　　both……表明嚴謹公正的態度，最后用but……很自然地引出了自己的論點。請看下面這個例子：

　　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.
