10、Dneedn't29The traffic _ stop when the lights are red.AmustBmustn'tCmayDcan't30You _ never play in the street. It's not safe.AcanBmayCmustDneed答案1Bcan't在此表示“不可能”。 may not表示“不可以”，mustn't表示“不准”， needn't表示“不必”。2B此题考查 had better的用法。 had better后接动词原形，表示“最好（做）”， had better的否定形式是

11、“had better not+动词原形”。 take off作“脱下（衣物）”讲。3Bmay和can在疑问句和陈述句中都可表示“许可”。4AWould you like？ 表示委婉的邀请或征询意见。 B、 C、 D 三个选项中的助动词不能与like搭配。5CA项的两个各选内容却不对。B项的错误是第一句虽然可用 mustn't，但第二空不能用 have to（表客观需要）。6D7AB方先说“不行（No），后面就是”命令式的言辞，（must），而不是说“可以（may）”做什么了。8A后一句说“他很快就康复了”，还可推测出前一句应是“不必着急。”9B在一般词句中用May表示“请求”。10Cmust 是此处表示猜测，意为“一定是”。11Dmust的古定回答用 needn't.12C13B在用Yes/No的答语中，前后的肯、否定形式必须一致。14C15A答案16B17C18Amay开头的问句的肯定答语仍用 may.19A主句中的must表“必须”，故附加部分用needn't.20C21D注意 need做情态动词可用于疑问和否定句，其构成分别为 Need sb. （do）？和 sb. needn't（do） need无人称变化。做实意动词时，构成Do（Does） sb. need to （do）？和sb. don'
