2．I think we've spent enough time on this problem---let's _______ more important matters now．（　　）
A．ask forB．look forC．turn upD．turn to

分析 我想我们已经在这个问题上花了足够的时间了，现在让我们谈谈更重要的问题．

解答 答案D．ask for请求…； 要求…； look for寻找（某人或某物）； turn up出现，到来，露面；开大，调高（收音机、暖气等）；turn to求助于；（使）转向；（使）变成；翻书到．根据上文的语境"I think we've spent enough time on this problem我想我们已经在这个问题上花了足够的时间了"可知下文表达的意思是"现在让我们谈谈（转向）更重要的问题"；故答案选D．

点评 本题考查动词短语的辨析．英语中有的词组没有捷径，只有平时加强记忆，要注意区别，记忆的时候不能忽视，这是常见的命题方式．平时要加强记忆，做题时，别忘了要结合上下文句意判断．

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（电池） are the biggest challenge．In the plug-in-vehicle world，Li-ion（锂离子）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．"

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．

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．
