A．有人认为X 是好事，赞成X， 为什么？
B． 有人认为X 是坏事， 反对X，为什么？
Some people are in favor of the idea of doing X. They point out the fact that 支持X 的第一个原因。They also argue that 支持X 的另一个原因。
However, other people stand on a different ground. They consider it harmful to do X. They firmly point out that 反对X 的第一个理由。 An example can give the details of this argument: 一个例子。
There is some truth in both arguments. But I think the advantages of X overweigh the disadvantages. In addition to the above-mentioned negative effects it might bring about, X also may X 的有一个坏处。
Many people argue that 错误观点。By saying that, they mean 对这个观点的进一步解释。An example they have presented is that 一个例子。（According to a survey performed by X on a group of Y, almost 80% of them 赞成这个错误观点或者受到这个错误观点的影响）。
There might be some element of truth in these people’s belief. But if we consider it in depth, we will feel no reservation to conclude that 与错误观点相反的观点。There are a number of reasons behind my belief. (以下参照辩论文的议论文写法)。
Nowadays, there exists an increasingly serious social/economic/environmental problem. (X has increasingly become a common concern of the public). According to a survey, 调查内容说明这种现象的情况。（或者是一个例子）。

What is the reason for this change? Mainly there are … (多少) reasons behind the situation reflected in the graphic/table. First of all, …(第一个原因). More importantly, …(第二个原因). Most important of all, …(第三个原因).
From the above discussions, we have enough reason to predict what will happen in the near future. The trend described in the graph/table will continue for quite a long time (if necessary measures are not taken括号里的使用于那些不太好的变化趋势).
Some people believe (argue, recognize, think) that 观点1. But other people take an opposite side. They firmly believe that 观点2. As for me, I agree to the former/latter idea.
There are a dozen of reasons behind my belief. First of all, 论据1.
More importantly, 论据2.
Most important of all, 论据3.
In summary, 总结观点. As a college student, I am supposed to 表决心.
或 From above, we can predict that 预测.
People hold different views about X. Some people are of the opinion that 观点1, while others point out that 观点2. As far as I am concerned, the former/latter opinion holds more weight.

For another, 论据2.
Last but not the least, 论据3.

There is no consensus [k?n'sens?s] 一致of opinions among people about X（争论的焦点）。Some people are of the view that 观点1，while others take an opposite side, firmly believing that 观点2。As far as I am concerned, the former/latter notion（观念） is preferable in many senses. The reasons are obvious.
First of all, 论据1。
Among all of the supporting evidences, one is the strongest. That is, 论据3。
A natural conclusion from the above discussion is that总结观点。
