　　一、开头句型

　　I....has both advantages and

　　disadvantages.……既有利又有弊。例如：

　　举一反三：

　　1.Although computers bring people a lot of convenience，they have many

　　disadvantages.

　　2....has many advantages.For example，...However，just as every

　　coin has two sides，...has its disadvantages.

　　(本例将利弊分开讲，转折过渡自然。just as every coin has two sides也很值得背诵。)

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

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

　　families can afford a car.

　　随着中国改革开放的深入，越来越多的中国家庭买得起车了。(“越来越多”除了常用的more and more外，还可以用an increasing number of， a growing number of，a significant number of，a great number of等来表达。)

　　本结构看似固定，实则富于变化，只要记住with有“随着”的意思，相信大家可以根据实际的需要造出更多的句子。

　　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.
