周翔圣托福听力讲义-辨音听写-12

周翔圣托福听力讲义-辨音听写序言在托福备考的过程中，往往不少老师都在说得听力者得天下，而很多老师也讲提高听力的唯一有效途径是听写，在早期的教课过程中，碰到太多学生埋怨整篇的听写太耗时，太费力并且往往有力无功。

是这套辨音听写是笔者本人在近6年的托福听力教学实践中总结和实践出来有针对性的提高中国考生听力能力的训练。

文章内容来源于科学美国人60秒（scientific american60s ），并通过笔者精心挑选取出了当中符合新托福听力考试内容的文章。

根据中国学生在听力训练当中遇到的难点比如连读，变音，失爆，弱音，有针对的提取出影响考生对句子理解的部分词组（词汇或短句）， 在加上科学美国人60秒（scientific american 60s ）原本就比较快的语速，这样的话能使考生快速有效的提高听力水平。

推荐使用方法：由于语速较快普通备考的学生前期很难一次听出原文中的内容，所以在练习的时候若有未听到的部分后退回去（答案就在每篇文章的末尾），反复体会直到反应出来为止。

听写完后再通篇连续听上1，2次检验自己对通篇文章(包括细节)的理解。

希望这套辨音听写的材料能为大家在托福备考的过程中有效的帮助大家。
