Today  1  people live in cities.So there is usually little room in a city to grow food.2   of the land in a city is used  3  homes, shops, roads and parks.

Most food for city  4  is grown in the countryside.It is often brought to the city by truck, train and plane.Some food is even carried into the city by car.

Do you live in a city? If you  5  , think of all kinds of food you eat in a day.All of the food comes from the countryside.The wheat(小麦)for your bread is grown on farms in the countryside.So are vegetables.

Water is   6  thing that cities get from the countryside.Everyone needs water every day.We use a little of it for  7.But we use even more to  8   bathtubs (浴缸), run showers, and wash streets.

The  9    used by cities comes mostly(主要的) from rain.But people cannot use the rain  that frills on cities.The rain  10  dirty as it falls  11  dirty air.Once it hits city buildings or streets, the rain will  12  more dirt(尘埃).It is not good for drinking  13  bathing.

So cities must reach out to the  14  countryside for water.There, the rain falls through  15   onto trees and grass.The fallen rain runs into rivers and lakes.So it is important to keep both cities and the countryside clean.
