两个我都不了解,不过呢,口语的提高首先是你的英文的综合水平的提高。阅读啊 ,写作啊,等等,the important thing is input .then you can output orally. i cant claim the master of it ,even though i am enlish major,but i think TEM8 is only a piece of paper. and u can have more information from 斑竹here.good luck
the more you practice,the fluent english you can speak. unfortuanately,my problem is my english speed is too fast, they cant catch it .so probably the point is express your idea clearly . right?
