　　断句：

　　(1)利用标点断句：双破折号之间内容单独成句;

　　(2)利用标点+从属连词断句：在in which 前面断开，前后长度均在5-15词之间，且结构完整。

　　语法分析：

　　主干成分—Grade inflation is often considered a product.

　　修饰成分——①双破折号之间内容为grade inflation的同位语，对Grade inflation进行解释说明;②介词短语of a consumer era作后置定语，修饰名词product;③介词短语in higher education作定语，修饰名词短语 a consumer era;④最后一部分为in which引导的定语从句。

　　难点分析：

　　①同位语the gradual increase in average GPAs(grade-point averages) over the past few decades，其中in average GPAs(grade-point averages) 为介词短语作后置定语，修饰gradual increase; over the past few decades定语，修饰average GPAs。②定语从句 in which students are treated like customers to be pleased，属于分隔结构，修饰a consumer era。其中，从句中的主干是students are treated，为主谓结构;like customers to be pleased为状语。

　　重点词汇：

　　Grade inflation 分数膨胀;consumer era 消费时代;product 产物

　　翻译：

　　分数膨胀，即过去几十年来平均学分绩点的逐渐上升，经常被视为高等教育中消费时代的产物，在这个时代中，学生们被当成需要被取悦的消费者。
