He tried to work hard in the past 42 years     he wasn't a lucky man and never caught a thief. He was often sorry for it.

Last weekend, when Mrs Clarke was cooking supper, she found there was no sugar. So she asked her husband      some in the shop near their house. He came in the shop and found a young man stealing some money from a woman's bag. He ran to the thief      , but the young man found and ran away at once. Mr Clarke ran after him. The thief ran into a blind alley（死胡同）and Mr Clarke caught him at last.

"Please give me a chance, sir,"said the young man."I never stole before."
