2016考研英语阅读长难句实例分析（82）
19.On the contrary,constraints on improvingproductivity I explain why education isn't developingmore quickly there than it is.
【分析】多重复合句。句子主干是constraintsexplain...。介词短语on improving productivity是constraints的后置定语，why引导的名词性从句作explain的宾语，其中包含than引导的比较状语从句。
【译文】相反，生产力的提高受到限制，正是那里的教育发展得不够快的原因。
【点拨】1)on the contrary是固定搭配，意思是“正相反”。2)constraint基本含义是“约束，限制”，通常与on搭配使用，另外它还有“拘束，态度不自然”的意思。

【译文】以这种方法看待新英格兰人通常意味着从这些清教徒的神学变革和他们关于教堂的与众不同的理念入手——这些是我们不容忽视的重要主题。
【点拨】动词短语take a/an…approach to sth.意思是“对…采用...方法/态度”。
