分析 我想我們已經(jīng)在這個(gè)問題上花了足夠的時(shí)間了,現(xiàn)在讓我們談?wù)劯匾膯栴}.

解答 答案D.a(chǎn)sk for請(qǐng)求…; 要求…; look for尋找(某人或某物); turn up出現(xiàn),到來,露面;開大,調(diào)高(收音機(jī)、暖氣等);turn to求助于;(使)轉(zhuǎn)向;(使)變成;翻書到.根據(jù)上文的語境"I think we've spent enough time on this problem我想我們已經(jīng)在這個(gè)問題上花了足夠的時(shí)間了"可知下文表達(dá)的意思是"現(xiàn)在讓我們談?wù)劊ㄞD(zhuǎn)向)更重要的問題";故答案選D.

點(diǎn)評(píng) 本題考查動(dòng)詞短語的辨析.英語中有的詞組沒有捷徑,只有平時(shí)加強(qiáng)記憶,要注意區(qū)別,記憶的時(shí)候不能忽視,這是常見的命題方式.平時(shí)要加強(qiáng)記憶,做題時(shí),別忘了要結(jié)合上下文句意判斷.

12.Car companies are developing vehicles that will plug into electric sockets,just like many laptops,digital cameras,cell phones and Mp4do.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 globe 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(電池) 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.a(chǎn)nd 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."

20.The passage mainly talks aboutD  of a new car
A.the developing    
B.the speed    
C.the appearance 
D.the batteries.
21.Which is true according to the passage?B
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.
22.How does Bohn feel about the future of the technology according to the last paragraph?A
A.Confident    
B.Puzzled.    
C.Worried. 
D.Disappointed.
23.According to the passage,the new technology is facing the following problems except thatC.
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.
