Question

【题目】—Has ISIS, the most shameful terrorist group, already been wiped off the earth?

—I guess not, but I think it ought to ______ .

A.be doneB.have beenC./D.have

Answer 1

【答案】B

【解析】

考查情态动词 + have done的用法。句意：——最可耻的恐怖组织ISIS已经从地球上被铲除了吗？——我想没有，但我认为理应被铲除。ought to + have + done表示过去应该做而实际并没有做，译成“理应做……”，故选B。
