16.Electric cars are dirty.In fact,not only are they dirty,but they might even be much dirtier than their gasoline-powered cousins.
People in California love to talk about"zero-emissions(零排放)vehicles",but people in California seem to be clueless about where electricity comes from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells,we get our electricity from generators(发电机).Generators are fueled by something-usually coal,oil,but also by heat generated in nuclear power plants.There are a few wind farms and geothermal plants as well,but by far we get electricity mainly by burning something.
In other words,those"zero-emissions"cars are likely coal-burning cars.Because the coal is burned somewhere else,it looks clean.It is not true.It's as if the California Greens are covering their eyes-"If I can't see it,it's not happening."Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity,you waste a nice part of that energy,mostly in the form of wasted heat-at the generator,through the transmission lines,etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won't get you nearly as far-so electric cars burn more fuel than gas-powered ones.If our electricity came mostly from wind,or geotherm,or solar,then an electric car truly would be clean.But for political,technical,and economic reasons,we don't use much of those energy sources.
In addition,electric cars'batteries which are poisonous for a long time will eventually end up in a landfill.And finally,when cars are the polluters,the pollution is spread across all the roads.When it's a power plant,though,all the junk is in one place.Nature is very good at cleaning up when things are not too concentrated,but it takes much longer when all the garbage is in one spot.

33.What does the underlined word"clueless"mean in Paragraph 2?D
A.People are seeing the California Greens everywhere.
B.People in California love to talk about zero-emissions vehicles.
C.People in California love to have their roofs covered with solar cells.
D.People there have no idea that so far electricity mainly comes from burning coal,oil,etc.
34.What is the main idea of the passage?A
A.Electric cars are not clean at all.
B.Electric cars are better than gasoline-powered ones.
C.People cast doubts on electric cars'batteries.
D.Gasoline is an efficient way to power a vehicle.
35.The electricity we get from a gallon of gas may make our car runD.
A.not less than 25 miles
B.more than 25 miles
C.no more than 25 miles
D.not more than 25 miles.

分析 电动车真的没有污染吗?通过文章的描述我们可以知道实际上并不是这样的,电动车比现在的汽车可能会导致更多的污染,因为它所使用的电,仍然是需要靠燃烧煤炭的资源来实现的.

解答 33.D 词义猜测题.根据文章第二段People in California love to talk about"zero-emissions(排放)vehicles",but people in California seem to be clueless about where electricity comes from.说明加利福尼亚的人喜欢谈论零排放的汽车,但是加利福尼亚的人似乎对电源的来源不清楚.该词应该指不清楚,不理解.
34.A 主旨大意题.根据文章第一句Electric cars are dirty.In fact,not only are they dirty,they might even be more dirty than their gasoline-powered cousins.说明电动车一点也不环保.故A正确.
35.D 细节理解题.根据第四段1,2行A gallon of gas may drive your car 25 miles.But the electricity you get from that gallon of gas won't get you nearly as far.一加仑汽油可能使你的汽车行驶25英里.但是你从那加仑汽油中得到的电力不会让你的车行那么远. 说明D正确

点评 本文通过反问:电动车真的没有污染吗?实际上并不是这样的,电动车比现在的汽车可能会导致更多的污染.提出观点,然后通过描述让我们认识这样一种事实.考生首先要仔细阅读短文,完整了解信息,准确把握作者观点.

8.Brad closed the door slowly as Sue left home to visit her mother.Expecting a whole day to relax,he was thinking whether to read the newspaper or watch his favorite TV talk show on his first day off in months."This will be like a walk in the park,"he told his wife,"I'll look after the kids,and you can go to visit your mom."
Things started well,but just after eight o'clock,his three little"good kids"-Mike,Randy,and Alex-came down the stairs in their night clothes and shouted"Breakfast,Daddy."When food had not appeared within thirty seconds,Randy began using his spoon on Alex's head as if it were a drum.Alex started to shout loudly in time to the beat(节拍).Mike chanted"Where's my toast,where's my toast"in the background.Brad realized his newspaper would have to wait for a few seconds.
Life became worse after breakfast.Mike wore Randy's underwear on his head.Randy locked himself in the bathroom,while Alex shouted again because he was going to wet his pants.Nobody could find clean socks,although they were before their very eyes.Someone named"Not Me"had spilled a whole glass of orange juice into the basket of clean clothes.Brad knew the talk show had already started.
By ten o'clock,things were out of control.Alex was wondering why the fish in the jar refused his bread and butter.Mike was trying to show off his talent by decorating the kitchen wall with his color pencils.Randy,thankfully,appeared to be reading quietly in the family room,but closer examination showed that he was eating apple jam straight from the bottle with his hands.Brad realized that the talk show was over and reading would be impossible.
At exactly 11:17,Brad called the daycare centre(日托所)."I suddenly have to go into work and my wife's away.Can I bring the boys over in a few minutes?"The answer was obviously"yes"because Brad was smiling.
