section three
choose the best choice from abc or d according to each passage.
(1)
for many years scientists have said that the earth is getting warmer. now they have found something new-hot cities! in the southern us, they have found that cities become very hot in summer. for example, the city of atlanta in georgia has rooftop temperatures of up to 50 degrees while it is 27 degrees in the streets! at night, the outsides of the building stay so hot that the heat of the city causes storm over the city.
china also has the same kind of problems. every year more farming land is used for factories or offices. more housing is needed, too. as people become richer, they buy more cars. now roads are needed and new car parks are built in the city centers. this all makes the city hotter.
it is not easy to change the situation. city planners say that we should plant more trees in the middle of cities. every new street should have trees on both sides, they say. trees make the temperatures lower, so we should have more trees in our parks and squares. also we should paint our roofs white. if we do this, they do not become so hot. every roof in a hot and sunny country should have solar roof panels. the electricity from these can be used to run the air conditioners in the building.
people continue to cut down forests around the cities. this makes the problem worse. cities are growing faster and faster. by the year 2025, 80% of the world’s population will be living in cities. if we go on like this, there will not be enough farmland to feed everyone in the world.
