Question

【題目】根據(jù)短文內(nèi)容，選擇最佳答案。
Car companies are developing vehicles that will plug into electric sockets, ust like many laptops, digital cameras, cell phones and Mp4 do. Called “plug-in vehicles”, these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual.
The technology is more than just cool. In our car-filled world, plug-in vehicles could reduce the amount of gas we use, which keeps rising in cost now and then. Besides, driving around in these vehicles may even help the environment. Gas-burning cars produce a lot of greenhouse gas, which causes global warming.
The first company-produced plug-in vehicles could hit the roads by 2020. But engineers still have a lot of work to do to make the technology practical and inexpensive.
Batteries are the biggest challenge. In the plug-in-vehicle world，Li-ion(鋰離子)batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a longer time between charges. Li-ion batteries can fit laptops, cell phones, heart instruments and other similar pocket ones.
But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving. What's more, the batteries are much expensive.
“A car filled with batteries could go a long distance,” says Ted Bohn, an electrical engineer in Chicago. “But it couldn't pull any people, and it would cost $100,000.” So researchers need to work out how to make batteries smaller and cheaper, among other questions.
“The answers don't exist yet,” Bohn says, “As a kid, I thought someone someplace knows the answer to everything. All of these questions haven't been decided. That's what engineering is about-making a guess, running tests and getting fine results.”
（1）According to the passage, the main problem of the new car is ______________.
A.the developing
B.the speed
C.the appearance
D.the batteries
（2）Which is true according to the passage?
A.The “plug-in vehicles” will use electricity completely as driving power．
B.The new technology will help protect our environment．
C.The technology of using electricity as driving is quite practical now．
D.The biggest challenge of the new technology is that it will cost us more energy．
（3）How does Bohn feel about the future of the technology according to the last paragraph?
A.Confident
B.Puzzled．
C.Worried．
D.Disappointed．
（4）According to the passage, the new technology is facing the problems except that_______．
A.the new technology cannot come into use at present
B.the cost of the new technology is quite high
C.the government won't support the technology
D.the size of the batteries is too big at present

Answer 1

【答案】
（1）D
（2）B
（3）A
（4）C
【解析】本文介紹充電式汽車的技術(shù)研發(fā)，主要談到電動汽車的優(yōu)點(diǎn)，技術(shù)突破，目前研發(fā)要解決的問題等信息。
（1）細(xì)節(jié)理解。根據(jù)Batteries are the biggest challenge可知電池是最大的挑戰(zhàn)，所以新能源汽車的最大問題是電池問題，故選D。
（2）細(xì)節(jié)理解。根據(jù)第一段的these cars will get most of their power from electricity可知這種汽車的大部分動力來源于電，故A錯誤；根據(jù)第二段的 driving around in these vehicles may even help the environment.可知這種汽車不使用燃油，可以幫助保護(hù)環(huán)境，故B正確；根據(jù)第三段中的But engineers still have a lot of work to do to make the technology practical and inexpensive可知科學(xué)家們正努力使這種技術(shù)變得更實用，所以C錯誤；根據(jù)第四段Batteries are the biggest challenge可知最大的挑戰(zhàn)是電池問題而不是能源問題，故選B。
（3）推理判斷。confident有信心的；puzzled困惑的；worried擔(dān)心的；disappointed失望的。根據(jù)最后一段中的As a kid, I thought someone someplace knows the answer to everything可知Bohn相信有人能解決這個問題，故選A。
（4）細(xì)節(jié)理解。根據(jù)文章最后兩段可知這項技術(shù)目前還不成熟，而且費(fèi)用太高（10萬美元），電池的體積太大，即ABD在文章中均可找到，只有C項文章未曾提及，故選C。
