yard sale庭院拍卖会
Yard sales are events in the US and Canada where people sell old things that they no longer want, on the grass in front of their house — their yard. People often hold yard sales in spring when they clean out their houses and get rid of things they don’t use or want anymore. People who plan to hold a yard sale will usually put up notices around their community and put up signs to point the way to their house.
