You might think all birds can only fly, eat, and sleep. But actually, there are a lot of birds that are very clever. I saw a Happy Birds Show at school. There were six birds on the show. The amazing thing was that all of the birds could sing! Because birds' beaks are not as flexible as our mouth, they have to try to make the words down in their throats (喉咙). One bird knew how to nod for "yes" and shake her head for "no". When the trainer asked the bird to kiss her, the bird shook her head. Then she asked,"Does my breath smell (口臭)? " and the bird nodded yes. Then the trainer was angry with the bird. As a result (结果), the bird turned upside down (倒过来), because she thought the trainer's breath was bad. In the end, the trainer said in anger, "Kiss me!" So the bird kissed her cheek with its beak. Now you know that birds can do many amazing things!
