At first, the students discussed the questions all in English, but after a while, they ______speaking in Chinese.

A．gave up    B．picked up    C．turned up    D．ended up

【回答】

D

【解析】句意：起初，学生全用英语讨论问题，但过了一会儿，他们以用汉语讲话结束。A. gave up 放弃；B. picked up捡起、拾起；C. turned up打开；D. ended up结束。根据语境可知，此处与“at first”相对应，所以使用“结束”之意。故选：D。
