What is a supermarket? In the dictionary, a supermarket is a large self-service department store. Some

second floor. Here you can buy things such as CDs, pens, clothes, TVs and refrigerator After you have collected
the things you want to buy on the second floor, you can go downstairs to the first floor where food and drinks
are sold (被卖到). You can also buy fresh fruit, vegetables and meat on this floor.
people like to go shopping in the supermarket. Here are some of the reasons (原因).
★ First, the prices are reasonable (合理的). The prices are lower than these in special shops and you can
choose whatever you want, without going place to place.
★ Second, the service is great. You can walk around freely and no one will ask you, "What can I do for
you?" If you can't find anything, just ask a service person and he or she will tell you where it is at once.
★ Third, the quality is good. If you get home and find the food bad, you can return it and they will say
sorry and change it for you.

go to the supermarket in order to save time and money.
