Question

【题目】Could you imagine a future changed by technology ________ our lessons are taught by robots rather than human teachers?

A. at which B. that C. which D. in which

Answer 1

【答案】D

【解析】考查定语从句。a future是先行词，后面是定语从句，“在未来我们的课被机器人教而不是人类”。in the future在未来，是固定短语；先行词是future，故后面的定语从句用in which引导，故选D。
