口语水平用英语怎么说？

一般不说口语水平,翻译起来也很生硬
直接说spoken English/oral English就可以了
how about your spoken English?
非要翻译口语水平那就是:proficiency in spoken English

如果你要的是独立结构，
可以说the level of his/her oral English.

如果你要句子：

What/How about his/her oral English?

How is her/his oral English?

How does she/he speaks English?

说法很多啦

Level of Oral English

the level of speaping english

oral english

English speaking ability
