Improve Your Oral English NOW！

1．自己要有改变口语现状的迫切要求，并开始行动。

2．要有一个方便的既能交流更能提高的语言环境。

3．持之以恒，细水长流，一步一个脚印。

4．学以致用，用了才能掌握。否则学了再多，浪费更多。

5．不要怕说错。养成“舌头先于大脑”的习惯，敢于说，敢于说错，然后才能说对。

6．学会用最简单的词来表达。李阳说过：简单重复，创造奇迹。

7．经常练习英语表达，如问自己：“What is a table?” 然后试着用英语回答后，再去翻英英字典对照答案。每天坚持问自己几个“ What is a…?”，获益良多。

8．多看一些原版的DVD片，同时大声模仿其中的对白。既练听力，又练发音，还练语感，一石三鸟。
