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.

When you meet someone for the first time, you will form an impression in your mind of that person in the first moment. Your reactions to other people, however, are really just barometers (晴雨表) for how you perceive(理解) yourself. Your reactions to others say more about you than they do about others. You cannot really love or hate something about another unless it reflects something you love or hate yourself. We are usually drawn to those who are most like us and tend to dislike those who display those aspects of ourselves that we dislike.
Therefore, you can allow others to be the mirror to illuminate (阐明;照亮) more clearly your own feelings of self-worth. Conversely, you can view the people you judge negatively as mirrors to show you what you are not accepting about yourself.
To survive together peacefully with others, you will need to learn tolerance. A big challenge is to shift your perspective from judgment of others to a lifelong exploration of yourself. Your task is to assess all the decisions, judgments you make onto others and to begin to view them as clues to how you can heal yourself and become whole.
Several days ago I had a business lunch with a man who displayed objectionable table manners. My first reaction was to judge him as rude and his table manners as annoying. When I noticed that I was judging him, I stopped and asked myself what I was feeling. I discovered that I was embarrassed to be seen with someone who was chewing with his mouth open and loudly blowing his nose. I was astonished to find how much I cared about how the other people in the restaurant perceived me.
Remember that your judgment of someone will not serve as a protective shield against you becoming like him. Just because I judge my lunch partner as rude does not prevent me from ever looking or acting like him. In the same way, extending tolerance to him would not cause me to suddenly begin chewing my food with my mouth open.
When you approach life in this manner, those with whom you have the greatest dissatisfactions as well as those you admire and love can be seen as mirrors, guiding you to discover parts of yourself that you reject and to embrace your greatest quality.The purpose of the author writing this passage is to advise people to _______.
| A．avoid inappropriate manners |
| B．judge others favorably in any case |
| C．pay attention to others’ needs and feelings |
| D．learn tolerance towards others |

| D．You can’t really love or hate others if they are similar to you. |
It can be implied from the text that __________.
| A．the writer’s first reaction to the man was to judge him as offensive |
| B．we shouldn’t focus on judging others but should constantly reflect on our own |
| C．we will need to learn tolerance to co-exist with others |
| D．the writer didn’t care about other people’s view of him |

If you are looking to putting a tree in your home for Christmas, there is always one debate that seems to arise in most households: whether you want a real tree or fake tree. Year after year, as we find ourselves cleaning old pine needles (松针) for months on end, we decide that we will never get another real tree. So that begs the question: Which kind of tree is better?
There is certainly a lot to be said for real trees. There is something fun about gathering the family together, going to a Christmas tree farm, and selecting or even cutting down your own tree. Real Christmas trees have that lovely holiday pine needle smell and they look great in your home.
Of course, on the other hand, they also leave a complete mess behind and needles that seem to keep appearing for weeks or even months after the tree comes down. You must also find a way to deal with your real Christmas tree after you’re done, which may mean cutting it into pieces so it will fit in the trash. Many dustmen will refuse to take away a tree that is left beside your regular trash, especially if it is a big tree or an old, yellow one with falling needles, making it hard to pick up. They don’t want a face full of sharp needles any more than you do!
With a fake Christmas tree, there is no mess, but there is also no Christmas smell and no exciting trip to the Christmas tree farm. Of course, these trees look the same in appearance as a real tree when decorated. Many of them come already with lights, so using that old, messy string of lights will be a thing of the past. For some people, a can of pine air freshener is enough to recreate the pleasant smell of a real tree.
As to which tree is the better choice, it is really a matter of personal preference. Both real and fake trees certainly have their benefits, and knowing which is better for you this Christmas really depends on what your family wants.Which of the following shows the benefits of real Christmas trees?
a.providing more fun

About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son’s teacher asked me to meet him at his office.
In the teacher’s office, an exchange of greetings was followed by his questions: “Is your son mentally retarded(弱智的)? Does he suffer from any kind of mental disability?”
Was he talking about my wonderful Scola? No, no, it can’t be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.
My son could not follow the teacher’s directions, he told me, and thus, Scola was disrupting the class. Didn’t he know my son did not speak English yet?
He was angry: “Why hasn’t your son been taught to speak English? Don’t you speak English at home?”
No, I didn’t speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn’t want him to forget his native language. Well, wrong answer! What kind of person would not speak English to her son at home and at all times? “Are you one of those people who come to this country to save dollars and send them back to their country, never wanting to be a part of this society?”
Needless to say, I tried to tell him I was not one of “those people.” Then he told me the meeting was over, and I left.
As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的).
Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places — something very basic and obviously lacking in the “educator” I met in New Jersey.The teacher asked the author to his office ______.
| A．to discuss Scola’s in-class performance |
| B．to get Scola enrolled in kindergarten |

Baths and bathing have long been considered of medical importance to man. In Greece there are the ruins of a water system for baths built over 3,000 years ago. The Romans had warm public baths. In some baths, as many 3,000 persons could bathe at the same time.
Treating disease by taking bathing has been popular for centuries. Modern medical bathing first became popular in Europe and by the late 1700’s has also become popular in the United States.
For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to keep clean was avoided, and perfume was often used to cover up body smells!
By the 1700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently. During the Victorian Age of the late 19th century, taking a bath on Saturday night became common.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “The Great Unwashed!” In one American city, for example, a person was only allowed to take a bath every thirty days! That was a law!
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health. Doctors know that dirty bodies increase the chance of diseases. As a result, in the United States, people generally bathe often. Some people bathe once a day at least. They consider a daily bath essential to good health.In the 18th century doctors believed that being clean was _______.
