Ⅰ.1.A　情态动词。句意:“布朗老师,我必须今天看完这本书吗 ”“不,你没有必要。你可以在两天之后看完。”在英语中,回答由must引导的一般疑问句时,否定回答用needn't,意为“没有必要”。故选A。
2.D　情态动词。句意:设计师尝试了每种可能的方法来让机器人变轻,所以你不必担心它的重量。must意为“必须”;may意为“可能”;can't意为“不能”;needn't意为“不必”。故选D。
3.B　情态动词。句意:你看起来如图图此虚弱!我认为你应该马上去看医生。should意为“应该”,表示委婉地提出建议。故选B。
4.D　5.B　6.A　7.B　8.B
Ⅱ.9.Does; need　10.No; needn't　11.Where should; put　12.needs to be cleaned
