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】句意：你能想象一个被技术改变的未来吗，那是我们的课程由机器人教而不是人类？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，所以答案是D。
