Question

阅读理解 　　There are more than 100 million cars in the United States．An ordinary car gets less than 15 miles from each gallon(加仑)of gas．It travels about 10, 000 miles each year．In that time，it uses about 650 gallons of gas．In all, automobiles use up some 70 billion gallons of gas a year．That comes out to be four-and-a-half million barrels a day． 　　The importance of saving gas, then, cannot be stressed too much．Let's say, the fuel used by each ear could be cut back just 15 percent．This could be done by making fewer trips each day．It could be done by keeping the automobiles in good shape．It could be done through better driving habits．If these were done, the nation's use of fuel would fall by close to two-thirds of a million barrels per day． 　　Everyone can help to save gas．One way is to take buses．Some could walk to work．Others could ride their bikes．Another way is to share a ride．People could share cars．About one-third of all cars are used for going to and from work．You can go shopping with a friend from time to time．If two people use a car instead of two, they all save．Driving stress(紧张)would be less, too, with fewer cars on the road．The savings on gas around the nation would come to more than one-half million barrels a day Still another way to save is by cutting out trips one does not need to take．Can you find one car trip per week that could be done by telephone?Can you combine trips?If each car traveled 1 0 miles less each week, they could save three-and-a-half billion gallons of gas a year．This comes to nearly 5 percent of the total passenger cars demand for gas． 　　The way people drive decides how much fuel they save．Careful drivers may get 20 percent more miles per gallon than ordinary drivers．They obey the 55-mile-per-hour speed limit．If just one gallon of gas were saved each week for each car in the country, a total of five-and-a-half billion gallons could be saved a year． (1) Which of the following statements is true about an average car according to the passage? [　　] A． An ordinary car run a lot more than 10, 000 miles with 650 gallons of gas． B． An ordinary car cannot run more than 15 miles with one gallon of gas． C． An ordinary car with ten gallons of gas can run more than 150 miles． D． An ordinary car can run 10, 000 miles each year with 70 billion gallons of fuel． (2) The passage mentions all of the following facts except that ________． [　　] A． keeping one's car in good shape helps one save gas B． riding buses instead of driving is helpful to gas saving C． sharing a ride or walking to work is another way to save gas D． driving stress can be greatly relieved by using less gas (3) According to the passage, it is possible to save five percent of the total passenger cars demand for gas each year, if ________． [　　] A． people all share car-riding instead of owning their own cars B． all the cars cut off one trip of 10 miles each week C． two people go shopping in a car from time to time D． people use telephones instead of riding cars (4) Which of the following statements best expresses the main idea of the text?

解析：

(1)	这是一道正误辨认题。根据短文第二句An ordinary car gets less than 15 miles from each gallon of gas，可判断出B项正确。
(2)	这是一道考查是否准确掌握短文中所提供信息的题目。文中未提及开车的紧张状况是由于使用较省汽油而得到缓解的信息。
(3)	该题考查细节。由短文第三段中If each car traveled 10 miles less each week, they could save three-and-a-half billion gallons of gas a year．This comes to nearly 5 percent of the total passenger cars demand for gas，可判断出B为最佳选项。
(4)	这是一道主旨大意题。全文叙述了节省汽油的重要性及几种节省汽油的方法，只有C项能概括全文大意。
