Air pollutionPeople and air pollution are often in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air pollution is the gas from cars. Statistics(统计资料) show that 93 percent of all auto trips are within cities.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 county.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.26. The key point of the passage is that().A. the cause of air pollution is peopleB. the causes and the effects of air pollution are both found in citiesC. the effects of air pollution range from headaches to death27.

Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.The cost of a personal car is high to the individual. The average person pays about $2,000 per car per year in gasoline, insurance, taxes, and maintenance. But for society as a whole, personal cars are a luxury we cannot afford. We pay in death from auto accidents, in poor health from air pollution, in loss of hearing from noise pollution, and in the destruction of our cities by the ever-increasing number of highways.1、It is ____ that are the main cause of the air pollution in Boston.A、vehicles in generalB、the public transportation systemsC、carbon monoxidesD、personal motor vehicles2、The writer’s purpose in writing this article is to _____.A、remind people of the danger of air pollutionB、warn people of the danger of accidentsC、urge people to use private cars as less as possibleD、ask the Boston government to build more homes and gardens3、According to the last paragraph, ______.A、the cost of personal cars is high to the individuals but not to the societyB、an average car costs about $2,000 inBostonC、personal cars are so expensive that most people cannot affordD、society as a whole suffers much from the ever-increasing number of cars4、It is implied but not stated that ______.A、garages, highways and parking areas occupy nearly one third of the total Boston downtown area.B、because of highways, people in Boston have no more homes and places to live, work and play.C、C garages have replaced most of the gardens in BostonD、Boston is the most seriously polluted city in the U.S.5、The best title for this passage is “ ______.”A、Air Pollution in BostonB、More Homes, More Plays for PeopleC、Cars Are Too ExpensiveD、Public Transportation, A Solution to Air Pollution

共用题干第三篇Preserve the EnvironmentThroughout history man has changed his physical environment in order to improve his way of life.With the tools of technology he has altered many physical features of the earth.He has transformed woodlands into farmland,and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains tobuild roads and railways.However,man's changes to the physical environment have not always had beneficial results.Today, pollution of the air and water is an increasing danger to the health of the planet.Each day thousands of tons of gases come out of the exhausts of motor vehicles;smoke from factories pollutes the air of industrialized areas and the surrounding areas of countryside.The air in cities is becoming increasingly unhealthy.The pollution of water is equally harmful.In the sea,pollution from oil is increasing and is killing enor- mous numbers of algae（水藻）,fish and birds.The whole ecological balance of the sea is being changed. The same problem exists in rivers.Industrial wastes have already made many rivers lifeless.Conservationists believe that it is now necessary for man to limit the growth of technology in order to sur-vive on earth.According to the passage,pollution of the air and water is caused by__________.A:thousands of tons of gases coming out of the exhausts of motor vehiclesB:the changes of the environment that technology has brought to manC:the increasing amount of oil that has been producedD:industrial wastes discharged into rivers
Many people use wood stoves and fireplaces to heat their homes．Scientists have become worried about the smoke that they give off．Harmful chemicals are in the smoke．The smoke is causing air pollution．The pieces of pollution,called soot,are floating in the air．They are too tiny to see．Scientists must use a microscope to see them. Small amounts of soot are safe,but large amounts can be dangerous．The govenment wants to limit this kind of pollution．It may stop people from using their fireplaces. The air is tested every day．When soot levels are high,more than 65 micrograms of soot per cubic meter,factories must stop making smoke．The government thinks that limit should be much lower.Factories produce the most smoke and soot．But the government thinks that all types of burning should be limited．The soot levels from factories and homes could be limited．Home owners may have to install new wood stoves that they comply with the new law．Or,they may not be able to bum on days when the air quality is bad. Residents of some towns are fined if they violate the burning ban．Scientists hope these new regulations will make the air cleaner and less harmful to breathe.Why is the air quality tested every day?A.Just in case someone askB.Scientists like to take testC.Scientists are not very busD.To keep track of pollution level
