U5情态动词may和不定式2022-2023学年牛津译林版八年级英语上册
8AU5语法情态动词may和不定式第一部分：情态动词may一、may的用法may是情态动词，因此具有情态动词的特点：第一，情态动词不随人称的改变而改变，没有三单形式；第二，情态动词后加动词原形。
二、may的句型肯定句：情态动词+动词原形He may be at home.They may be having a class now.（may be doing）否定句：情态动词的否定句直接在情态动词后加notHe may not be hungry.一般疑问句：情态动词的一般疑问句直接将情态动词提前。
May I borrow the bike?三、may的考点（1）may表示推测，意为可能，用于肯定句和否定句，例1. He may be at home.例2. The little girl may not be so careless.（2）may表示请求许可，意为可以，常用于疑问句，否定回答不用may not，用mustn’t例1.---May I help you?----Yes, please./No, thanks.例2. ---May I go out with my friends, mum? ----Yes, you can./No, you mustn’t.另外May I help you?可以用于售货员询问顾客的场景。
用”I would like”或”I need” 来回答。
例1.---May I help you，Mrs. Li?---I want to buy a dress for my daughter.四、拓展（1）May I help you?的同义句除了may之外，还可以用might，can和could。
例Can I help you?=May I help you?（2）maybe和may的转换例1.Maybe he is not interested in music. = He may be not interested in music.例2.Maybe he will come to the show.=He may come to the show.（3）may表示祝愿：例1.May the year ahead bring you good luck, fortune, success and lots of love.祝愿即将到来一年为你带来好运、财富、成功和许多的爱。

关于语法may的用法解析
关于语法may的用法解析推荐文章情态动词英语语法知识点热度：最新英语语法的学习方法热度：初一英语上册语法汇总热度：初一英语上册语法汇总热度：高考英语语法总结归纳热度：大家对英语的语法了解有多少呢?如果不知道的可以看小编是怎么表达的，接下来，小编给大家准备了关于语法may的用法解析,欢迎大家参考与借鉴。
关于语法may的用法解析(1)“may”表达许可例：You may have the cake now.(现在你可以吃蛋糕了。
)例：May I come in?(我可以进来吗?)解说表达“许可”无“may…”与“can…”的区别：“may…”通常表达说话者的许可。
例：You may go home now. (=I allow you to go home now.) (你现在可以回家。
=现在我准你回家。
)例：May I borrow your towel?(我可以借用你的毛巾吗?)No, you may not.(不行，你不可以借用我的毛巾。
)“can…”表达“许可”时用法比较随便。
例：You can go home now.本句可作如下的两种解释：1.你现在可以回家。
——我准你回家。
2.你现在可以回家。
——如老师要我转告你说“你现在可以回家”，或者如既然你已把工作做完了，按规定“你现在可以回家”等。
第2.的解释法并非说话者的“许可”。
换言之，“can…”可以表达第三者的“许可”，或“客观条件的许可”。
例如我们看到一个男生要走进女用洗手间，我们就可以对他说：That’s a lady’s toilet. You can’t go in there.像这种场合，假定你说“You may not go in there.”并不很通顺，也会被误为你是洗手间的管理员了。
请再注意下列两句意思的区别：例：May I smoke here?(我可以在此吸烟吗?——请示对方的“许可”。
)例：Can I smoke here?(这里我可以吸烟吗?——询问对方这里是否禁止吸烟。
