句式升级策略

替换简单并列句：

原句：Air pollution is bad. It affects our health.

升级：The detrimental effects of air pollution, particularly on public health, have aroused widespread concern.

使用形式主语结构：

It is universally acknowledged that...

There exists a consensus that...

逻辑连接词优化

避免过度使用firstly/secondly，替换为：

To begin with, More importantly, Consequently

增加对比关系词：

Whereas, By contrast, Conversely

学术写作禁忌

禁用缩写(don't→do not);

避免主观表述(I think→Evidence suggests)。
