Another major kind of dirty air is the burning of coal and oil for energy.This energy is needed to make electricity.Of course,much more electricity is used in the city than in the country. On the average,we throw away more rubbish than the year before.The burning of rubbish makes air pollution even worse.Many major industries are also responsible for the dirty air in the around cities.The fumes(烟)from iron,steel,chemical,and petrol production add particles(微粒)to the air. The effects of air pollution range from mild headaches to death.The levels of pollution found in heavy traffic may cause headaches for loss of clear vision.Wherever coal and oil are used for fuel,fumes may kill trees and plants and cause metal to corrode(腐蚀).In some of the larger cities,these fumes endanger the lives of human beings by contributing to lung diseases and causing early death. 1.The key point of the passage is that________. [答案]B.the causes and the effects of air pollution are both found in cities 2.What is the purpose of this passage? [答案]A.to persuade people to stop polluting the air 3.Why is air pollution more grave in the city than in the country?

THESE IDEAS ARE EASY TO FOLLOW: 1.Get your car [答案]B to make sure everything works properly.Whenever possible,walk,cycle,carpool,or use public transportation.Buy fuel-efficient vehicles.Drive at 60 mph or less to improve gas mileage. 2.Burn less natural gas [答案]A Instead,use a solar cooker or heater and wear extra layers. 3.Become a vegetarian or a vegan.[答案]E requires more land and emits more carbon dioxide than simply growing crops directly for human food. 4.[答案]D Coal power plants produce most of the world’s electricity,and they also produce more carbon dioxide than any other source.Coal plants also release many other pollutants.Unplug televisions,cell phone chargers,and other appliances while not in use.Most devices continue to use small amounts of power even when they’re turned off.Avoid using air conditioning,and don’t leave the fridge open any longer than necessary.Only run the clothes washer or dish washer when full.Rather than using a dryer,hang clothes on a line to dry in the sun.
