My sister, a primary school teacher, was informed by one of her pupils that a bird had built its nest in the tree outside the classroom. 

What kind of bird?" my sister asked. 

"I didn't see the bird, ma' am, only the nest," replied the child. 

"Then, can you give us a description of the nest?" my sister encouraged her . 

"Well, ma'am, it just resembles your hair. " 

我姐姐是一位小学老师。一次一个学生告诉她说一只鸟儿在教室外 的树上垒了个窝。
