Most rubbish is made up of things we can't eat or use. If we kept these things we would soon have a mountain of rubbish. In some cities, the rubbish is collected and taken outside of the cities to a dump (堆存处). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs and other places. To keep nice and keep flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or school may be built there, and then you'd never know that this was once an old rubbish dump. In other cities the rubbish is burnt in special places. The fire burns everything but the metals. Sometimes the metals can be used again in factories where they slowly change into something called humus (腐殖质), which looks like black earth. It is rich with the kinds of things that feed plants and help them grow. 7. You can most probably read the passage in _____. A.a newspaper B.a TV guide C.a history book D.a note book 8.
