《2026年全效学习中考学练测英语外研版》

题目：—Can I watch TV now? —No，you （mustn't/can't/needn't）. You （can/must） do your homework first.
解析：此题考查情态动词的基本用法。can能；会；can't一定不，不可能；must必须，一定；mustn't禁止；needn't不必。句意：——我现在能看电视吗? ——不，你不能。你必须先做家庭作业。故分别填入can't和must。
归纳总结：情态动词在不同的语境中表示不同的含义，所以解题时要根据具体的语境分析句子的意思，选用正确的情态动词。同时还要注意说话人的语气，结合具体的语境来分析和判断。
