B解析试题分析：考查情态动词， will: 构成将来时；shall:可用于将来时，主语为一人称；May表示可以，请求对方做某事；Need表示需要，其否定形式是needn’t，所以选B，句子意思“我将给您打开电视可以吗？奶奶”考点：考查情态动词
点评：情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。值的注意的是，中学阶段的情态动词常考额有13个，can-could may-might should-ought to had better will-would need have to .考生应注意对这13个情态动词的用法多总结，多运用。即学即练：-Life ____ be very hard for people living in the north of Canada as it isvery cold there in winter.—Yes, the weather there _____ be as low as 60℃ below zero.A.must; can B．shall; must C．will; should D．has to; can选A
