阅读理解
An American group developed the rooftop（外屋顶）gardening in the early 
1980s . The group is known as ECHO . This idea was to help people living in cities 
who didn’t have to grow vegetables . And now it is becoming more and more popular in many other countries .
      To build a rooftop garden，four things are necessary . You need a roof strong   enough and four pieces of wood to build a box . Grass cuttings in which to plant your garden and a thin piece of plastic on which to pit the cut grass are also necessary. 
     Begin by testing（检测）your roof to make sure it is strong enough . Cut and 
collect some grass . Cover the roof with a thin piece of plastic . Then you build a box from the four pieces of wood . The box has no top or bottom . It should be about 8 cm deep . It can be as long and wide as needed. Put the box on the plastic . Then fill it  with the cut grass . Water the grass and push it down by walking on it . After about three weeks ，the rooftop box is ready for planting.
      Put the seeds(种子)directly into the wet grass. It is important than the grass is kept wet until the plants begin to grow .When the plants are growing, you will need to water them every day unless it rains. And birds must be prevented from eating the seeds or new plants. They will also need some liquid fertilizer(液体化肥).You can make your own liquid fertilizer if you can get wastes from chickens. Put the chicken wastes in cloth bag .Then put the bag in a big container of water .After about one week, the water becomes a good liquid fertilizer.
      The rooftop garden is a good place to grow peas, tomatoes and onions .If the box is deep enough, potatoes and carrots will also grow.
