coherence and cohesion（连贯性和凝聚力）
（1）量大-量小；量小-量大；差距大-差距小；差距小-差距大
（2）每句话之间都要有明确的关联
（3）使句子间有关联度的方法：
1）确定分类：按分数高低分 2）反复强调分类：
a.- with + 比较级 取决于你的对象
（with lower band / with worse performance ）
b.强调其他的方向：用差距/趋势-doing来连缀句子
*如何替换漂亮的比较级：思考题目的比较对象
如：学生的成绩： weaker – poorer – better
商品的价格：more expensive, cheaper
