I wonder whether there is any girl or boy who does not like to see a rainbow in the sky. It is so beautiful.
There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away.
A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the effect of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow（弓).
That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds.
Every rainbow has many colours in the same order. The first or the top colour is always red, and the next comes orange, then yellow, and last of all, blue. A rainbow is indeed one of the wonders of nature.

Mr Smith was ill and he went to see a doctor． The doctor asked  him to put out his tongue（舌头）， and then he said， “OK， You can put your tongue back now． There’s nothing wrong with you， but I’m afraid you have a problem． You hardly ever take exercise．”
　 “But， doctor，” Mr Smith said， “I don’t think so．”
　 “Don’t tell me what you think，” the doctor said， “I know    what you need．　I see a lot of people like you． None of them goes  any exercise． They sit in offices all day and in front of the        television in the evening． You must walk quickly for at least（至少）20 minutes a day．”
　 “I don’t want to hear any excuse（借口），” the doctor said． “You must find time for exercise． If you don’t， you will get fat and have health problems．”
　 “But I walk every day，” Mr Smith said．
　 “Oh， yes， and I know what kind of walking that is． You walk a few meters to the bus stop from your house， a few more meters from  the bus stop to your office， and a few more meters from your office  to your dining–room for lunch and back． That’s not a real walk．  I’m talking about a walk in the park or by the lake for twenty      minutes every day．”
　　“Would you please listen to me， doctor? Mr Smith said， getting a little angry with his doctor．
　　“I’m a postman，” Mr Smith went on， “and I walk for nearly（几乎）seven hours every day．”
　　For a moment the doctor was silent（沉默的）， then he said      quietly， “Put out your tongue again， will you?”

An old lady went to the shop last Sunday. She passed a bank and saw a car near the door. A man got out of it and went into the bank. She looked into the car. The keys were in the lock(锁).
