Question

【题目】If you have a headache , you ____ lie down for a good rest .

A. shouldn’tB. had better notC. had betterD. must

Answer 1

【答案】C

【解析】

句意：如果你头疼，你最好躺下好好休息。

本题考查情态动词。A shouldn’t 不应该；B had better not 最好不要；C had better 最好；D must 必须。had better+动词原形是“最好做某事”，表示建议。本句中应该是建议，A、B不符合句意，D选项语气过去强硬，故选C。
