A.用must来提问,肯定回答用Yes, you must;否定回答用No, you neednt 或No , you dont have to, 故选A.2. C. 完全否定的猜测用cant,;“mustnt”表“ 禁止、不许”,不用在否定猜测中,排除; “may not” 表“可能不是”,用在不确定猜测中,但根据“Mr Li has gone to America.”可知 may not不符合句意,排除;“neednt”表“不需要”,不符合句意,排除。3. B.rubbish与throw之间存在被动关系,用被动语态,排除C、D;其次,往河里扔垃圾这个行为是禁止、不许的,而不是不需要,排除A。4. D. 用must来提问,肯定回答用Yes, you must;否定回答用No, you neednt 或No, you dont have to, 故选D。5. D.need和dare既可以当情态动词,又可以当实义动词。当情态动词时,need/dare 后接动词原形,无人称和数的变化,否定句直接在后面加not;当实义动词时,need/dare 后接不定式,有人称和数的变化,且否定要用助动词。A项的neednt,not家在need后面,所以need是情态动词,后应接动词 原形,排除;B项的need前有助动词dont, need是实义动词,后应接不定式,排除;C项need前也有助动词,need为实义动词,后应接不定式,排除C。6. B.had better最好做某事,后接动词原形,其否定形式直接在better后面加not, had better not最好别做某事,且not 后接动词原形。7. B.ought to ,应该做某事,其否定形式为 ought not to,缩写为oughtnt to,排除C;对在医院吸烟这个态度应该是“不应该”,而不是“不需要”或“可不”,排除A、D。
