刚刚看一个学生在看新概念课本，偶也翻开看了两眼， ，在前言部分看到了几句非常简单的话，但高度总结了学习英语的规律：
the following order of presentation must be taken as axiomatic:
nothing should be spoken before it has been heard.
nothing should be read before it has been spoken.
nothing should be written before it has been read.
speaking and writing are the most important of these skills, since to some extent they presuppose the other two.
所以，要学好听力，一定也要先学好另外三个方面。英语学习四个方面是互相促进，千万不要孤立地只练听力。
