Question

【题目】You might be trapped in an elevator emergency, in _____ case you should stay calm and call for help.

A.thatB.whichC.whoseD.its

Answer 1

【答案】B

【解析】

考查定语从句。句意：你有可能被困于电梯的紧急事故中，在这种情况下，你应当保持镇定并呼救。本句中为非限制性定语从句，所设空处指代You might be trapped in an elevator emergency整句内容，且在定语从句中置于介词之后，因此用关系代词which，故选B。
