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

supermarkets have two floors. When you enter such a supermarket,an elevator (电梯) will take you to the

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.

    ★Nowadays many people don't have much time to walk from one shop to another, so people choose to

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

    ★What's more, if you don't want to buy anything,you can just come and look around in the supermarket.

It's a good place to have a walk.
