I used to dream about Pisa when I was a boy. I read about the famous building called the Leaning Tower of Pisa. But when I read the word Pisa, I was thinking of pizza. I thought this tower was a place to buy pizza. It must be the best pizza in the world, I thought. Many years later I finally saw the Leaning Tower. I knew then that it was Pisa end not pizza. But there was still something special about it for me. The tower got its name because it really does lean to one side. Some people want to try to fix it. They are afraid it may fall over and they do rat like the way it looks. I do not think it's a good idea to try to fix it. The tower probably will not fall down. It is 600 years old. Why should anything happen now? And, if you ask me, I like the way it looks. I like the way it leans over the city. To me it is a very human kind of leaning. Nothing is perfect, it seems to say. And who cares? Why do people want things to be perfect? Imperfect things may be more interesting. Let's take the tower in Pisa. Why is it so famous? There are many other older, more beautiful towers in Italy. But Pisa Tower is the most famous. People come from all over the world to see it.

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
