Mr.Smith is one of my friends. He can run very fast and he is always ready to show( 显示 ) how fast he can run. One day a thief( 小偷 ) breaks into( 闯入 )his house , takes some things of his and runs off as fast as he can. Mr.Smith runs after him and shouts( 喊 ) : “Stop! Stop! Don't you know you can't run away from me?” But the thief only runs faster. Mr.Smith gets angry. He tries his best to run. He is soon a few miles away from his house. He doesn't see anything or anybody and is still rushing( 冲 ) alone( 单独地 ) when he runs into( 撞到 ) me. “Why are you in such a hurry?” “I'm trying to catch a thief.” “But where is the thief?”I ask. “Far , far behind me , ”says Mr.Smith with a smile on his face. “He thinks he can run faster than me , but you see he is wrong.”
