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

A Ride in a Cable-carA ride in a cable-car is one of the exciting and enjoyable experiences a child can have.InSwitzerland,which is the home of the cable-car,it is used mostly to take tourists up the slope of a mountain,to a restaurant from which one can have a bird-eye view of the surrounding country, or to a top of a ski-run,from which,in winter,skiers glide down the snow covered the slope on skis .In Singapore,however,the cable-car takes one from the summit of a hill on the main island to a low hill on Sentosa,a resort island just off the southern coast.The cable-car is really a carriage which hangs from a strong steel cable suspended in the air.It moves along the cable with other cars on pulleys,the wheels of which are turned by electric motors. The cars are painted in eye-catching colours and spaced at regular intervals.Each car can seat up six persons.After the passengers have entered a car,they are locked in from outside by an attendant,they have no control over the movement of the car.Before long,the passengers get a breath-taking view through the glass windows of the modern city,the bustling harbour,and the several islands off the coast. The car is suspended so high in the air that slips on the sea look like small boats,and boats like toys.On a clear day,both the sky above and the sea below look beautifully blue.In contrast to the fast-moving traffic on the ground,the cars in the air move in a leisurely manner,allowing passengers more than enough time to take in the scenery during the brief trip to the island of Sentosa.After a few hours on Sentosa,it will be time again to take a cable-car back to Mount Faber. The return journey is no less exciting than the outward trip. Which of the following about the cable-cars is true?A: The cars move along the steel cable.B: The cars are operated by a driver.C: The cars are controlled by the passengers.D: The cars move on wheels.

Every day 25 million U.S. children fideschool buses. The safety record for these buses is much better than forpassenger cars; but nevertheless, about 10 children are killed each year ridingon large school buses, and nearly four times that number arc killed outsidebuses in the loading zones. By and large, however, the nation′s school childrenare transported to and from school safety.
Even though the number of school buscasualties (伤亡事故) is not large, the safety of children is always of intense publicconcern. While everyone wants to see children transported safely, people aredivided about what needs to be done particularly whether seat belts should bemandatory (强制).
Proponents of seat belts on schoolbuses--many of them parents and medical organizations argue that seat belts arcnecessary not only to reduce fatality and injury, but also to teach children lessonsabout the importance of using them routinely in any moving vehicle. A sidebenefit, they point out, is those seats belts help keep children in theirseats, away from the bus driver.
Opponents of seat belt installation suggestthat children are already well protected by the school buses that adhere to theNation Highway Traffic Safety Administrations (NHTSA) safety requirements setin 1977. They also believe that many children won′t wear seat belts anyway andthat may damage the belts or use them as weapons to hurt other children.
A new Research Council report on school bussafety suggests that there are alternate safety devices and procedures that maybe more effective and less expensive. For example, the study committeesuggested that raising seat backs four inches may have the same safetyeffectiveness as seat belts.
The report sponsored by the Department ofTransportation at the request of Congress, reviews seat belts extensively whiletaking a broader look at safety in and around school buses.
It may be inferred from this passagethat ______.查看材料A.many of the opponents (反对者) of seat beltinstallation are parents and officials of the Department of Transportation
B.proposals of seat belts on school buseswould be seriously considered
C.an alternate safety device raising seatbacks four inches may be taken into consideration
