学习难度
英语用 may、can、be allowed to 和 let 结构表达许可。may 较正式或礼貌，can 更常用于日常口语，be allowed to 明确表示规则允许。
You may leave now.
may + leave：may 表示许可，意思是“你现在被允许离开”。
常见易错点
学习者在选择 can 和 may 时，可能听起来过于正式或过于随便。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
