I have always heard that walking under a ladder brings bad luck, but I have never thought so. I have walked under ladders many times, but I have never met anything bad before. It’s the same with black cats. People say if a black cat crosses before you, it means bad luck. I have never thought that until this afternoon. But ever since I heard my student Sam’s story, I have begun thinking about whether it was true.
This afternoon, Sam was walking down the street thinking about something, so he wasn’t paying attention to where he was going; he walked right under a ladder standing against a building. A black cat ran out of a door just at that moment, and Sam fell over it. His head hit the ladder. A man washing the window was at the top of that ladder and the dirty water went down through the air. Poor Sam! He got wet all over.
True or false.
( ) 1. At first, the writer believed that walking under a ladder would bring bad luck.
( ) 2. The writer has walked under ladders many times, and he has met something bad many times.
( ) 3. There was a man washing the window near the building.
( ) 4. The writer’s student, Sam had a bad luck that afternoon.
( ) 5. It’s really true that walking under a ladder or with black cats will bring bad luck to you.

Our eating habits are very important for good health. Many people like eating sweets and ice-cream more than meat and rice. Sweets and ice-cream are not bad for stomach if we eat them at the end of a meal. But if we eat them before a meal, they may take away our appetite. It is important for us to eat our meals at the same time every day. When we feel hungry, it is said that our body needs food. When we feel angry or excited, we may not want to eat.
A long time ago, in England, some judges used to decide whether a person was telling truth by giving him some dry bread. If the person could swallow the bread, it showed that he was telling the truth. Though this seems rather strange and foolish, it is indeed a way to find out the truth, sometimes. A person worrying about something has much difficulty in swallowing anything dry. Because he is worrying, he loses his appetite and does not want to eat.
Choose the right answer.
( ) 1. We must develop a good eating habit if we want to .
A. be angry B. eat more C. be hungry D. be healthy
( ) 2. It is good to eat sweets or ice-cream .
A. before a meal B. after a meal C. at any time D. during the day
( ) 3. We may not want to eat when .
A. we feel hungry B. we feel angry
C. the meal is ready D. we finish our work
( ) 4. When a person has nothing to worry about, he usually .
A. has a big appetite B. has a poor appetite
C. wants to drink C. wants to eat sweets
( ) 5. “Swallowing something” means .
A. eating and drinking B. eating something dry
C. eating something fast D. eating something slowly
D B B A C
