原文及翻译

Sometimes, a merchant will boast that he paid one dollar for a glass or china cup at a yard sale and sold it for $100 at his store or on the internet. By having catalogs that show the value of collectibles, dealers can sometimes make large profits. 

有时，商人会夸口说他在庭院拍卖会上花了一美元买了一个玻璃杯或瓷杯，然后在自己的商店或网上以 100 美元的价格卖出。通过拥有显示收藏品价值的目录，经销商有时可以获得巨额利润。

Now, however, many of the people having yard sales will try to check the value of the things they are selling first, so it is getting harder to get a real bargain. One reason for yard sales is that North Americans often live in big houses, which fill up with things. 

然而，现在许多进行庭院拍卖的人会先检查他们所卖物品的价值，因此越来越难获得真正的便宜货。庭院拍卖的一个原因是北美人通常住在大房子里，里面堆满了东西。

People may use the basement, the attic, the spare room, and the garage to store things that they aren't using. If they store things in their garage, all they have to do is open the garage door and have a garage sale. 

人们可能会使用地下室、阁楼、空余房间和车库来存放他们不使用的东西。如果他们把东西存放在车库里，他们所要做的就是打开车库门，进行庭院拍卖。

When children grow up and move away, the parents will often sell the children's old clothes, toys, and furniture. Another reason for yard sales is that there are a lot of things that people might like but don't want to pay full price for. 

当孩子长大并搬走时，父母通常会卖掉孩子的旧衣服、玩具和家具。庭院拍卖的另一个原因是有很多东西人们可能喜欢但不想支付全价。

For example, if someone likes to read novels, they may be happy to pay one dollar for a book at a yard sale rather than 20 or 30 dollars at a retail store.

例如，如果有人喜欢读小说，他们可能愿意在庭院拍卖会上花一美元买一本书，而不是在零售店里花二十或三十美元。
