4．The market is crowded with people __________．（　　）
A．trading and bargainB．trade and bargain
C．trading and bargainingD．trade and bargaining

分析 市場(chǎng)里滿(mǎn)是做買(mǎi)賣(mài)和討價(jià)還價(jià)的人．

解答 答案：C．根據(jù)句子結(jié)構(gòu)The market （主語(yǔ)）is crowded（謂語(yǔ)） with people （賓語(yǔ)）可知trade and bargain做people的定語(yǔ)，因?yàn)閮烧咧g是主動(dòng)關(guān)系，表示做買(mǎi)賣(mài)和討價(jià)還價(jià)的人，所以答案是C．

點(diǎn)評(píng) 考查非謂語(yǔ)動(dòng)詞做定語(yǔ)．現(xiàn)在分詞和過(guò)去分詞在句中都可以作定語(yǔ)，但在語(yǔ)態(tài)和時(shí)間概念上有區(qū)別，在語(yǔ)態(tài)上，現(xiàn)在分詞表主動(dòng)，過(guò)去分詞表被動(dòng)，在時(shí)間上，現(xiàn)在分詞表示動(dòng)作正在進(jìn)行，而過(guò)去分詞則表示動(dòng)作完成．

9．CORVALIJS．Ore．--Engineers at Oregon Suite University have made a breakthrough in the performance of microbial （微生物的）fuel cells that can produce electricity directly from wastewater．opening the door to a future in which waste treatment plants not only will power themselves，but will sell extra electricity．
The new technology developed at OSU； can now produce 10to 50more times the electricity，per volume，than most oilier approaches using microbial fuel cells．a(chǎn)nd 100times more electricity than some．
Researchers say this could eventually change the way that wastewater is treated all over the world，replacing the widely used"activated sludge （泥漿）"process that has been in use tor almost a century．The new approach would produce significant amounts of electricity while effectively cleaning the wastewater，
"If this technology works on a commercial scale the way we believe it will，the treatment of wastewater could be a huge energy producer，not a huge energy cost？，said Hong Liu，an associate professor in the OSU Department of Biological and Ecological Engineering．"This could have an impact around the world，save a great deal of money，provide better water treatment and promote energy sustainability．"
The biodegradable （能降解的）characteristics of wastewater，if developed to their full potential，could theoretically provide many times the energy that is now being used to process them，with no additional greenhouse emissions．
OSU researchers reported several years ago on the promise of this technology，but at that time the systems in use produced far less electrical power．With new concepts，the technology can now produce more than two kilowatts per cubic meter of liquid reactor volume．
The new system also works better than an alternative approach to creating electricity from wastewater，based on anacrobic （臭氧的）digestion that produces methane （甲烷）．It treats the wastewater more effectively，and doesn't have any of the environmental drawbacks of that technology，such as production of possible release of methane，a significant greenhouse gas．

47．What can we learn about the new technology from the passage？B
A．It can produce 100limes more electricity than any approach used today．
B．Through it more electricity can he created and water can be cleaned better．
C．It has already changed the way that wastewater is treated all over the world
D．It has opened the door to put microbial fuel cells to productive use．
48．What attitude does Professor Liu hold towards the new technology？A
A．Supportive．
B．Critical．
C Unconcerned．
D．Curious．
49．According to the last paragraph，why does the new system work better than the alternative approach？A
A．Because it is co-friendly and treats wastewater more effectively．
B．Because it can make lull use of anaerobic digestion producing methane．
C．Because it may produce less methane than the alternative approach．
D．Because it can produce 10limes the energy than the alternative approach．
50．Which of the following best expresses the main idea of the passage？D
A．The treatment of wastewater is a huge energy cost．
B．Wastewater is being treated differently over the world．
C．Waste treatment plants have found a new way to power themselves．
D．Microbial fuel cells will produce more electricity from wastewater．

16．We arrived on Christmas morning，at Bridgetown Harbor in Barbados．Our crew on the Olympia Voyager has warned and rewarned us of the dangers of exploring the 166-square mile island-country on our own．But my wife，Kate，said all she wanted to do was go for a quick swim and do a bit of walking near the harbor．Despite my misgivingswe were one of the first couples off the gangplank（跳板）．
"Let's grab a local taxi and take it to a beach，"said Kate．"What if we miss returning to the Olympia Voyager before she sails？"I asked．
"You worry too much．"
A twenty-year rusty car stopped，and a smiling man who claimed to be a taxi driver reported he was ready to take us swimming．
"How much？"I asked．
"Five dollars，"he said．
His name was Vincent Clarke，who did not appear to have any guns or knives．
"Sounds fine，"said Kate．She started to get in the taxi．
"Just hold on，"I said．"I want to ask Vincent a question or two．"
"Ask me anything，"he said．"I have no secrets．"
"We have been told that you may take us into the hills and rob us and kill us．"
"No，I will not harm you．It is a serious crime to kill a tourist．I will cost you five dollars and I promise you that I will get you back to the Olympia in plenty of time．"
"Let's go，"said Kate．She got in．
We drove for about three minutes and parked at a beach，and while Kate swam，Vincent and I talked as Christmas music played on his taxi radio．Some time later，Kate retimed to the taxi．Then Vincent drove us to the power plant，and a university，and then we sped through a poverty-stricken area．When we arrived，Vincent charged us twenty dollars．Five dollars a person each way．The tour，he said，was free．
Free indeed!
I thanked Vincent for not killing us and only charging us four times his original quote（報(bào)價(jià)）．

    A．mistakes．B．difficulties．C．worries．D．tiredness．
43．From the passage we know the author's wife wasB．
    A．uninterested in the trip．B．independent-minded．
    C．a(chǎn)fraid to meet strangers         D．eager to explore the island country alone
