what与which的区别could you tell me ____language your friend speak 选what 还是which
答
这是一个宾语从句，这里应该选用which表示为哪一种语音。
答
i think "which",mean:which language not speak what!
答
这需要具体语境来选，如果列出几种选项来，例如你知道他说的是法语日语英语里的一种，这时候选which。。。
如果没语境what 和 which 都行。。
趋向于选which、。。
但是用在非限制定语从句就得用which了。。。例如
The language ,which your friend speaks , is good.
答
both are ok
答
Could you tell me which language your friend speak
Could you tell me what your friend speak
