Electric cars are dirty. In fact, not only are they dirty, 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 most all 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 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 drive 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 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. 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.

1.A 2.C 3.D 4.D 5.D  【解析】 试题分析: 1.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。 2..C 推理题。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。故C正确。 3.D 细节题。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说明D正确。 4.D 推理题。根据文章最后两段,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,故电动车是对环境是更有害的。故D正确。 5.D 推理题。根据文章第二段内容可知电动车所需要的点,是需要通过燃烧煤炭等自然资源的,所以电动车并不如人们所认为的那样清洁无污染。故D正确。 考点:考查环境类短文阅读

When the Japanese attacked America’s ships at Pearl Harbor on 7 December 1941, they did it secretly. The makers of the movie Pearl Harbor have behaved differently.

The noise about Pearl Harbor, made by Disney,has reached its highest point with its premiere (首次公演) before the movie opens in cinemas across the US at the start of the Memorial Day holiday weekend, a time to recall national heroes who sacrificed their lives on the battlefield.

As Ben Affleck is the main star, the movie seems sure to become a success in the United States at least.

At almost three hours in length, it promises to be a good old Hollywood movie. There is a love story. Affleck and his co-star, Josh Hartnett, both fall in love with the navy nurse, Kate Beckinsale and, of course, there is much human courage and love of country.

It’s certain that Disney will be accused of “changing” history. The showing of actual events in a movie always causes arguments.

Bits of the story are deliberately not mentioned in the movie. It does not address the theory held by some historians that President Franklin Roosevelt knew about Japan’s intention to attack the ships in Pearl Harbor.It is said he did nothing, as he was aware that such a blow would allow him to take America into the Second World War.

Japan remains sensitive about being accused of wartime atrocities (暴行). And Disney is sensitive about its business in Japan, where it has a theme park.

Not all the reviews of the movie have been full of praise. A reviewer for Newsweek, who was given an early preview, acknowledged that the 40-minute sequence (连续镜头) showing the attack itself was powerful. The attack comes quite late in the movie, however, and the reviewer was less impressed with the characters and the love story.

“Almost every line of the dialogue sounds like it comes from an old movie, ” the reviewer wrote.

1.From the passage we can infer that the Memorial Day refers to           

A.the day the United States was founded

B.the day people remember their ancestors

C.a day people celebrate the victories of World War Ⅱ

D.a day people remember those who died in wars

2.From the passage we know that Ben Affleck             .

A.regarded Josh Hartnett as an enemy

B.may be a very popular movie star

C.experienced the Pearl Harbor Incident

D.was in love with the actress Kate Beckinsale

3.Which of the following statements is TRUE about Pearl Harbor?

A.The movie will cause a lot of arguments.

B.The movie has made the Japanese angry.

C.The movie truly describes the Pearl Harbor Incident.

D.The movie shows that President Roosevelt knew about Japan’s intention.

4.According to the passage, what does the reviewer for Newsweek think of the movie?

A.The scenes of the attack leave no impression.

B.The dialogue in the movie is original and creative.

C.The attack scenes occupy too much time of the movie.

D.The characters and the love story are less attractive.

There was a time in my life when beauty meant something special to me. I guess that would have been when I was about six or seven years old, just several weeks or maybe a month before the orphanage(孤儿院)turned me into an old man.

I would get up every morning at the orphanage, make my bed just like the little soldier that I had become and then I would get into one of the two straight lines and march to breakfast with the other twenty or thirty boys who also lived in my dormitory.

After breakfast one Saturday morning I returned to the dormitory and saw the house parent chasing the beautiful monarch butterflies who lived by the hundreds in the bushes scattered around the orphanage.

I carefully watched as he caught these beautiful creatures, one after another, and then took them from the net and then stuck straight pins through their head and wings,pinning them onto a heavy cardboard sheet.

How cruel it was to kill something of such beauty. I had walked many times out into the bushes,all by myself, just so the butterflies could land on my head,face and hands so I could look at them up close.

When the telephone rang the house parent laid the large cardboard paper down on the back cement(水泥)step and went inside to answer the phone. I walked up to the cardboard and looked at the one butterfly who he had just pinned to the large paper. It was still moving about so I reached down and touched it on the wing causing one of the pins to fall out.It started flying around and around trying to get away but it was still pinned by the one wing with the other straight pin.Finally its wing broke off and the butterfly fell to the ground and just trembled.

I picked up the torn wing and the butterfly and I spat on its wing and tried to get it to stick back on so it could fly away and be free before the house parent came back.But it would not stay on him.
