2.Electric cars are dirty.In fact,not only are they dirty,but they might even be more dirty than their gasoline-powered cousins.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.Power plants mostly use fire to make it.Apart from the few people 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 (地热) 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 extremely 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 drive your car 25miles.But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones.If our electricity came mostly from wind or geothermal,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 (垃圾填埋场).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 a lot longer when all the garbage is in one spot.
29.Which of the following words can replace"be clueless about"in Paragraph 2?A
A.fail to understand. B.be familiar with.
C.be curious about. D.show their interest in.
30.The electricity we get from a gallon of gas may make our car runB.
A.at least 25miles B.less than 25miles
C.more than 25miles D.as far as 25miles
31.In the author's opinion,compared with cars using gas,electric cars are moreC.
A.efficient B.expensive
C.harmful D.environmentally-friendly
32.It can be inferred from the passage thatD.
A.electric cars'batteries are no longer poisonous in the landfill
B.now electric cars are used more than their gasoline-powered cousins
C.zero-emissions vehicles should be chosen to protect our environment
D.electric cars are not clean since we get electricity mainly by burning something.
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等资源来实现的.
解答 29--32 ABCD
29.A 词义猜测题.根据第二段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,但是加利福尼亚人似乎对电源的来源不清楚.该词应该指不清楚,不理解.故选A.
30.B 细节理解题.根据第四段第一、二句"A gallon of gas…the electricity you get from that gallon of gas won't get you nearly as far…"可知,同样用一加仑的汽油,电能汽车所能行驶的路程及不上燃油汽车,即不会超过25英里.故选B.
31.C 推理判断题.根据最后两段,不仅仅是电动车的需要的能源更多,而且电动车的电池也会导致污染,故电动车对环境是更有害的.故选C.
32.D 推理判断题.根据第二段内容可知电动车所需要的能源,是需要通过燃烧煤炭等自然资源来获得,所以电动车并不如人们所认为的那样清洁无污染.故选D.
点评 新闻一般采用"倒金字塔"式结构(即先说结果,再说重要事实,最后说次要内容),但有的通讯叙述方比较灵活多变,有顺叙、倒叙、中间或许还会有插叙、补叙等叙述方法,这就要求我们在阅读时特别关注.必须在十分有限的时间内运用略读、扫读、跳读等技巧快速阅读,搜寻关键词、主题句,捕捉时空、顺序、情节、人物、观点,并且理清文章脉络,把握语篇实质.

Habits are powerful factors in our lives.Because they are consistent,often unconscious (43)B,they constantly,daily express our character and produce our effectiveness or ineffectiveness.
As Horace Mann,the great educator,once (44)Bit,"Habits are like a rope.We weave a string of it every day and soon it cannot be broken."I personally do not agree with the last part of his (45)C.I know habits can be learned and unlearned.But I also know it isn't a(an) (46)Cfix.It involves a (47)Aand a faithful commitment.
Those of us who watched the lunar voyage of Apollo II were quite amazed as we saw the first men walk on the moon and return to earth.(48)Ato get there,those astronauts obviously had to break out of the huge gravity pull of the earth.(49)Benergy was spent in the first few minutes of(50)Din the first few miles of travel,than was used over the next several days to travel half a million miles.
Habits,(51)C,have huge gravity pull more than most people realize or would (52)C.Breaking deeply(53)Ahabits such as delay,hesitation,impatience,criticalness,or selfishness that go against basic principles of human effectiveness (54)Bmore than a little willpower and a few minor changes in our lives."Lift off"(55)Ba great effort,but once we break out of the gravity pull,our freedom(56)Aa whole new dimension.
(57)Cany natural force,gravity can work (58)Dus or against us.The gravity pull of some of our habits may (59)Dbe keeping us from going where we want to go.But it is also gravity that pull that keeps our world together,that keeps the planets in their orbits and our universe in order.It is a powerful force,and if we use it effectively,we can use the gravity pull of habit to create the cooperation and(60)Dnecessary to establish effectiveness in our lives.
