你会怎么写开头？比如：

句铺设背景。第二句话简单说一下两者都蛮重要的。第三句话表明立场，说出你觉得更重要的。

是不是很老套？老套到都不需要写个示例你都可以自行脑补？是不是有点傻？因为你也确实感觉有些僵硬。

怎么避免这个情况呢？看看下面这个开头：

The idea underlying the statement is biased. As a matter of fact, we cannot make a fair comparison between Internet access and public transportation in terms of which one is more worth the investment, since either, under one circumstance, may be more important than the other and less important in another circumstance.

句话已经表达了立场，只是措辞没有直白到“我不同意”。

第二句话是一个递进的信息。把立场进一步明确了。

第二句话里的原因状语从句值得注意：since either, under one circumstance, may be more important than the other and less important in another circumstance。你回忆琢磨研究体会一下either的用法（提示：此处为代词）。
