12．阅读理解

The weather has always been much talked about in our daily life. But bad weather is sometimes hard to stop, no matter who he is-rich or poor, young or old-in every part of the world. Maybe that is why there are so many expressions about the weather, especially about rain

Sometimes, when you need rain, you do not get any. Other times, you get rain when you don't want it. Take a football game for example. A sudden heavy rain can stop a wonderful game, making the players and the 20, 000 persons watching the game run for cover. If the game can't go on, people who have bought the tickets are given "rain checks". These are special tickets that will let them watch a later game for free.

"Rain checks" now means a second chance at something. Often, a rain check has nothing to do with rain.

Shops may give you a "rain check" when they sell something all out-a TV set, for example at a special low price. After all the TV sets are gone, the shop gives rain checks to those who wanted to buy one. The rain check lets a person have another chance to buy the TV set later, at the same low price, after the shop receives some more from the factory

"Rain check" is also used in our daily life. It's a way of accepting invitation, but for a later time. You may ask for a "rain check if you are asked to a friend, s house for dinner, but can't be there. You say, "T would love to join you for dinner, but I'm busy. Could I have a rain check?" You are asking, in other words, if you could join your friend for dinner at another time.
