she speak English is better than you还是speaking English /(ㄒoㄒ)/~

都不对，应该是：She speaks English better than you (do).

首先一个句子中如果没有and之类的词，不能出现两个或两个以上动词。
我觉得正确的应该是Her spoken English is better than you.她的口语比你的好。
如果仅限于提问的问题，我支持speaking English 虽然不是很地道，但是句子结构是正确的。

你要表达的是什么呢?
1. 她的口语比你好
应该是Her spoken english is better than you.
2.她英语说的比你好
she speaks englih better than you.
she speaks better englih than you .

her spoken english is better than you

都不对,可以说成：
1.She speaks English better than you.
2.She is better at speaking English than you.
3.She does better in speaking English than you.
注意：简单句一般只有一个谓语动词.

这句话有问题。。。is和speak都是动词啊,不能同时用 = =
she speaks English better than you
或者，her English is better than yours
