我不会英文请不要说英文怎么写

Sorry, I don't speak English. Please don't talk English to me.

Sorry, I know little about English, can you speak Chinese instead ?

这样翻属于意译。
显然你不是不会说英语，只是会的少一点。而且既然说了不太会英语，潜在的含义就是你们不要用英语了，就不用直白的让别人不用英语说了。之后，那就是希望人家用中文。

Sorry, I can't speak English. Could you speak Chinese?
对不起，我不会说英语。你能说中文吗?

用could更为polite（礼貌）。

哈哈 都够不礼貌的
Sorry, but could you speak in Chinese?

sorry，I'm not good at English ,please don't speak in it

I can't speak English,please use French、German、Japanese、Korean、Chinese、Greek et.
