     One morning, Mr Smith comes into the garden at the back of his house. He sees much snow in the

garden. He wants to drive his car out, so he asks a man to clean the road from the garage(车库) to the

gate. He says to the man, "Don't throw any snow on that side. It will damage(损坏) the flowers in my

garden, and don't throw any on the other side, for it will damage the wall and don't throw any into the

street, or the policeman will come." Then he goes out.

     When Mr Smith comes back, the road is clean. There is no snow on the flowers, on the wall or in the

street. But when he opens the garage to get his car out, he sees the garage is full of snow and the car is
