Question

【题目】You _______ her more help, even though you were really busy.

A.might giveB.must have given

C.ought to have givenD.ought to give

Answer 1

【答案】C

【解析】

考查情态动词。句意：你应该给她更多的帮助，即使你真的很忙。must have done表示“对过去情况的肯定推测”，should/ought to have done表示“本应该完成，却未完成”；由语境可知，此处指“本应该给却未给她的帮助”，用ought to have given。故选C项。
