14.Hybrid cars (混合动力车) are cars that run on petrol and electricity.They have a small standard petrol engine and a battery (电池) electric motor to provide electric power.There are some differences between different models of hybrid cars,but the general principle is that the car runs on petrol,and the electric motor kicks in when additional power is required,for example,when going uphill or accelerating.In some hybrid cars the petrol engine turns itself off when not needed,for example when the car has stopped at traffic light,keeping only the electric engine running.
Conventional cars have large engines to deal with driving uphill and accelerating.Hybrid cars have much smaller petrol engines,improved by electric motors when needed,so they use less petrol.Another way that fuel consumption is cut is by a system of"regenerative (再生的) braking".The electric motor is used to slow down the car,rather than conventional brakes.The energy produced by slowing the car is changed into electrical power,which is automatically stored in the battery.In effect,the battery recharges when you brake.In conventional cars the energy produced when braking is wasted.
In 1928Ferdinand Porsche built an experimental hybrid car.The first mass-produced hybrid car,the Toyota Prius,came out in Japan at the end of 1997.However,hybrid cars became available in the USA only in 1999.As they use less fuel,hybrid cars are cheaper to run.There are also many voices in place to encourage people to buy them.In some countries,hybrid car owners pay a lower rate of tax,and don't have to pay on certain roads.In some cities,hybrid cars are allowed to park for free.

A.were first available in the USA B.will gain more popularity
C.free their owners from tax D.are free to park anywhere in the city
35.The main purpose of this text is toC.

B.encourage people to buy hybrid cars
C.inform people a kind of energy-saving cars
D.explain why hybrid cars use less energy.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了一种新型的节能汽车的节能原理,使用时所带来的好处,让人们了解这种新车.
解答 32.C.细节理解题.由第一段中的"the general principle is that the car runs on petrol,and the electric motor kicks in when additional power is required"和第二段中的"Hybrid cars have much smaller petrol engines,improved by electric motors when needed,so they use less petrol."可知,混合动力车在需要时有电力支持,所以比传统汽车消耗的能源少,故选C.
33.A.细节理解题.由第二段中的"The energy produced by slowing the car is changed into electrical power,which is automatically stored in the battery.In effect,the battery recharges when you brake.In conventional cars the energy produced when braking is wasted."可知,在再生的刹车系统中,减速时所产生的能量被转变成电能,自动储存在电池里,而在传统的汽车里,这些能量就被浪费了,故A项正确.
34.B.推理判断题.由文章最后一段最后一句可知,使用混合动力车的车主可以交较低的税,在某些公路上不需要付费,甚至有些地方可以免费停车,这些都给使用这种车的人带来了好处,将会大受欢迎,故B项正确.
35.C.写作目的题.文章主要介绍了一种新型的节能汽车的节能原理,使用时所带来的好处,让人们了解这种新车,故C项切题.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
