根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多途选项。

  Laser(激光)is short for Light Amplification by Stimulated Emission of Radiation.Laser light is different from daylight or electric lights.Industry put lasers to work almost immediately after they were invented in nineteen sixty.  1  

  The first medical operation using a laser took place the year following its invention.Doctors Charles Campbell and Charles Koester used a laser to remove a tumor from a patient's eye at Columbia-Presbyterian Hospital in New York City.  2  

  Lasers have made measurement an exact science.Astronomers have used lasers to measure the moon's distance from Earth.  3  .For example, drawing a perfectly level straight line on a construction site is easy using a laser.

    4  .And the jewelry industry uses lasers to write on the surface of the world's hardest substance, diamonds.

  Lasers are found in many products used almost everywhere.Over one hundred years ago, writers imagined that beams of light could be powerful weapons.Today, lasers guide missiles and bombs.American defense companies are working on giant laser guns recognizable to science fiction fans everywhere.  5  

  Scientific American magazine says huge lasers turn only about twenty to thirty percent of the energy they use into a laser beam.The rest is lost as heat.

  That has not stopped scientists from working to perfect powerful lasers that, one day, may be able to shoot missiles out of the sky.

A.But weapons were not the first to use it on the list.

B.All lasers have several things in common.

C.Mappers and builders use laser technology every day.

D.But there are technological difficulties.

During sunrise he would  37 a break and climb up the fence so that he could see the house with golden windows  38  the distance. He thought  39  great it would be to live there and his  40  would wander to imagine the modern equipment and electric devices that might  41  in the house. “If they could  42  the golden windows, they  43  have other nice things.” He then  44  himself, “Some day I will go there and see that wonderful place.”
Then one morning his father told him to stay at home and he would do the everyday jobs.  45  that this was his chance, he packed a sandwich and 46  the field towards the house with golden windows.

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.What’s the main idea of the passages?

A.Electric cars aren’t actually clean.

B.Electric cars are zero-emissions vehicles.

C.Zero-emissions vehicles are popular.

D.Gasoline-powered cars are more efficient.

2.Which of the following words can replace “be clueless about” in Paragraph 2?

A.Be familiar with.

B.Be curious about.

C.Fail to understand.

D.Show their interest in.

3.The electricity we get from a gallon of gas may make our car run _________.

A.at least 25 miles

B.more than 25 miles

C.as far as 25 miles

D.less than 25 miles

4.In the author’s opinion, compared with cars using gas, electric cars are more __________.

A.environmentally-friendly

B.expensive

C.efficient

D.harmful

5.It can be inferred from the passage that __________.

A.electric cars' batteries are poisonous for a long time

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 in that we get electricity mainly by burning something
