The other day my brother and I went to the cinema by bicycle.My brother was riding with me sitting on the seat behind.As we came to the crossroads(十字路口) a young man and a girl came up and stopped "We've found you at long last,"they said, "but we didn't know them.Pointing to a policeman not far away,the young man explained. "He stopped us about half an hour ago and made us catch the offender.So come on,stand here.Hope you don't have to wait as long as we did.Good luck.
