1、一、 教学目标：情态动词 may 表示可能性及动词加带 to 的不定式的用法。二、 教学重难点：动词加带 to 的不定式的用法三、 学习与交流：May 的用法(1) 表示许可，意为“可以”。如：May I come in? 我可以进来吗？You may take everything you like. 你喜欢什么就拿什么吧。(2) 表示推测，通常用于肯定句和否定句中，意为“可能”。如：He may be very busy now. 他现在可能很忙。He said that she might not be at work today. 他说她今天可能不上班。(3) can 和 may 都可
2、表示可能性，can 通常用于否定句和疑问句，而 may 则通常用于肯定句和否定句。虽然两者均可用于否定句，但其意思不同：cant 意为“不可能”，may not 意为“可能不”。如：It cant be true. 那不可能是真的。It may not be true. 那可能不是真的。用动词+带 to 的不定式的用法下面动词经常使用带 to 的不定式。agree begin decide fail forget hope learn plan prepare remember try want等四、典型题例根据括号中中文提示或依据所给单词用适当形式填空。1 Thank you for_(同意
