People have some useless or old things and they no longer want them. Yet it seems wasteful to throw them away. So they may say, "Let's have a yard sale. "
They put them outside their houses and put on a "For Sale" sign. This is called a yard sale. In some other parts, it might be called a garage sale. Sometimes the sellers put an announcement（布告） in a local newspaper. It tells when and where the yard sale will take place. It also lists some of the things to be sold. These sales are very popular during weekends in spring, summer and autumn, Sometimes, there are more clothes than anything else. Cooking equipment（炊具） is also popular. So are books, tables and chairs. Then there are objects such as old toys or tools which are called "white elephants". A white elephant is something that you think is extremely（极其） expensive and useless.
Usually the seller puts a price on each object at a yard sale. However, that price may not be the final price. A table marked "Ten Dollars" may be sold at five dollars at the end of the day. Some people go to the yard sale because they enjoy the hunt.
