1．A hybrid electric vehicle （混合動(dòng)力車） or HEV is a vehicle driven by the combination of petrol engine and electric motor．Terrence has been driving a HEV for five years．He really doesn't understand why more people aren't accepting them． "I probably spend about ＄7 a day on petrol，" the taxi driver told news．com．a(chǎn)u．In his previous conventional vehicle Terrence said he was spending up to ＄30 a day on petrol，meaning he saves almost ＄6000 every year．
   The Toyota spokesman said this was quite a high saving and official tests estimate （估計(jì)） an average driver would only save about 33 percent off their current bill．This means a driver paying ＄30 a day on petrol would see their bill drop to about ＄20 using the hybrid． "A taxi driver that drives in built-up areas and spends little time on highways will notice a higher fuel saving，" he said． "Low speeds allow the electric motors to be used more and the petrol engine used less．"
   While some people are skeptical about how reliable hybrids are，Terrence said he had never run out of power．His Camry cost about ＄34，000 and so after five years，it's nearly paid for itself． "For cab drivers，it's a real advantage because of the cost-effectiveness，" he said．Terrence has no complaints about the car． "I love it，the calm and quietness of it，the simplicity of it-you just jump in and go．The maintenance（保養(yǎng)）is really low．But the only difficulty is finding someone to service the car as there are not many experienced mechanics（機(jī)修工）．"
   Terrence said it's "extraordinary" that more drivers aren't buying more hybrid electric vehicles and that governments are not encouraging this more． "I think people have a view that you have to plug it in，which is not true．A lack of information about the cars may be stopping people from taking the plunge．It's not promoted at all for the public to understand-it's simplifying the actual owning of a car-you don't have to do so many things to own it and run it，it's just so much simpler．Why wouldn't the government promote such a thing？"

（1）How much does an average driver save each day by driving a hybrid，according to the Toyota spokesman？

A．＄30．
B．＄20．
C．＄10．
D．＄7．
（2）Terrence's problem with his HEV at the moment is about the

A．speed
B．power
C．price
D．service
（3）When saying "extraordinary"，Terrence thinks it is

．
A．understandable
B．wonderful
C．doubtful
D．unbelievable
（4）What does Terrence think prevent the popularity of hybrid cars？

A．The difficulty in servicing the car．
B．The restriction of the government．
C．The lack of information about HEV．
D．The inconvenience with charging the car．

3．The Hadza hunter-gatherers of Tanzania live a life that has not changed much over ten thousand years.They have no crops，no house animals，no permanent shelters.In spite of long exposure to agriculturalist groups around them，the Hadza have maintained their lifestyle.
   The story of the spread of agriculture is the story of growing population density （密度）.Villages formed，then cities，then nations.Agriculture's rise，however，came with a price. It introduced infectious diseases，social inequality，occasional famines （饑荒） and war.Professor Jared Diamond of UCLA （University of California，Los Angeles） has called the adoption of agriculture "the worst mistake in human history"— a mistake from which we have never recovered.
   Looking at the Hadza，you can see why he came to this conclusion.They do not engage in warfare.They do not live densely （稠密地） enough to be threatened by an infectious outbreak.They have no known history of famine （饑荒）.The Hadza diet is more stable （穩(wěn)定的） and varied than that of most of the world's citizens.They live almost entirely free of possessions.They enjoy an extraordinary amount of leisure time， "working" — actively pursuing food — only four to six hours a day.
   The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland is not an inviting place.Recently，however，population growth has brought a flood of people into Hadza lands.The region has generally been viewed by outsiders as unused，a Place in need of development.The Hadza，who by nature are not a combative （好戰(zhàn)的） people，have almost always moved away instead of fighting.
   There are many things to envy about the Hadza，mostly what free spirits they appear to be.Free from schedules，jobs，bosses，bills，traffic，taxes，laws，social duties and money.But who of us could live like them？It's incredibly risky.Medical help is far away.One bad fall from a tree，one bite from a snake，and you're dead.The fact is that it's too late for us to go back to the Hadza lifestyle.Of greater concern is that soon it may be impossible for them to maintain theirs.

（1）What does the underlined word "It" in paragraph 2 refer to？

A．Agriculture's rise.

C．The formation of village.
D．The appearance of a city.
（2）What's the characteristic of the Hadza？

A．They are always busy in all seasons.
B．They like fighting with the other nations.
C．They are often in hunger because of fight.
D．They are always leading a free life without fight.
（3）What can be learned from the last paragraph？

A．It's convenient for the people of Hadza to get medical care.
B．It's worth visiting the beautiful scenery of the Hadza.
C．Visitors can be welcomed warmly by the people of the Hadza.
D．The author is worried about the current situation of the Hadza.
