1. Supermarkets are stores that sell food and many other things. Supermarkets are larger than grocery shops. They sell cheaper food than small shops.
Shopping in a supermarket is often quicker than in small shops because you can choose the food yourself. Small shops are friendlier than supermarkets. You can get to know the shopkeepers better.
I think markets are more interesting places than supermarkets because they are busier and more crowded with lots of noise and people.
In big cities there are department stores that sell almost everything. These are easier places to shop in than markets because everything is in one place, but they can be more expensive.
