Question

【題目】Since he has finished most of his homework at school, he _______ stay up late to finish it.

A.can'tB.couldn'tC.needn'tD.mustn't

Answer 1

【答案】C

【解析】

句意：既然他在學(xué)校已經(jīng)完成了大部分的家庭作業(yè)，他就沒(méi)必要熬夜來(lái)完成作業(yè)。

考查情態(tài)動(dòng)詞。can’t不能，不可能；couldn’t不可能；needn’t沒(méi)必要；mustn’t禁止。根據(jù)“he has finished most of his homework at school”可知此處表示“沒(méi)必要熬夜”，用needn’t。故選C。
