Electric ears 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 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. 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. It's just because the coal is burned somewhere else that it looks clean. It is not. 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 bum more fuel than gas-powered ones. If our electricity came mostly from nukes; or geothermal,or hydro, or solar, or wind,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 too concentrated, but it takes a lot longer when all the garbage is in one spot.

What does "clueless" mean in paragraph 2?

    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.

What is the main idea of the passage?

    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 powera vehicle.

The electricity we get from a gallon of gas may make our ear run         

    A. not less than 25 miles            B. more than 25 miles

    C. no more than 25 miles             D. not more than 25 miles

According to the passage, electric cars                  .

    A. do not burn fuel and more environmentally-friendly

B. are toxic because it is difficult for nature to clean it up when their

   batteries are buried in one spot.

    C. are very good at cleaning up when things are not too concentrated

    D. are poisonous for a long time and will eventually end up in a landfill

It can be inferred from the passage that                 

    A. being green is good and should be encouraged in communication

B. electric cars are not clean in that we get electricity mainly by burning

   something

    C. zero-emissions vehicles should be chosen to protect our environment

D. electric cars are now the dominant vehicle compared with gasoline-powered

   cousins

Our coach, Tony Severino, came out of his office at 6 o’clock. He told the team how   27   this game was for the season, between two of the state’s top teams—my school and our opposing team, Liberty High School. His words gave the team impulse (冲动) it needed to   28  .

At 7:10 pm, warm-ups finished, we went over the game   29   and discussed what we needed to do for the next three hours. The sound of the national anthem (庄严正式的歌曲)  30   that we were only minutes from the action. Our coach usually made a final   31  . But tonight was different. On this clear night he   32   looked around the room at all the players and shouted, “Let’s go and get them.” Even   33   the “get” came out of his mouth, we were already   34   our way out of the door.

Outside, a few young fans reached to touch our hands, eager to be a   35   of our school’s winning tradition. When I smiled and   36   my hand, the young faces lit up as if they had just met Superman. 

Seconds later, the team ran onto the   37  , moving as a mass of blue, in front of a packed stadium. We enjoyed a noisy   38   from fans and the fight song played by our school band. Breathing in the   39   of one of the biggest game of the year, I felt we were sure to win. I told myself, “This was what it was all about” and   40   that it was for moments like this that I loved high school football.
