Hybrid cars （混合动力车） are cars that run on petrol and electricity. They have a small standard petrol engine and a battery (电池) electric motor to provide electric power.
There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example, when going uphill or accelerating. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic light, keeping only the electric engine running.
Conventional cars have large engines to deal with driving uphill and accelerating. Hybrid cars have much smaller petrol engines, improved by electric motors when needed, so they use less petrol. Another way that fuel consumption is cut is by a system of "regenerative (再生的) braking". The electric motor is used to slow down the car, rather than conventional brakes. The energy produced by slowing the car is changed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In conventional cars the energy produced when braking is wasted.
In 1928 Ferdinand Porsche built an experimental hybrid car. The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997. However, hybrid cars became available in the USA only in 1999. As they use less fuel, hybrid cars are cheaper to run. There are also many voices in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don't have to pay on certain roads. In some cities, hybrid cars are allowed to park for free.

It was one of the hottest days of the dry season. We had not seen rain in almost a month. The crops were dying. Cows had stopped giving milk. The streams were long gone back into the earth. If we didn’t see some rain soon we would lose everything.
I was in the kitchen making lunch for my husband and his brothers when I saw my six-year old son, Billy, walking toward the woods. He was obviously walking with a great effort... trying to be as still as possible. Minutes after he disappeared into the woods, he came running out again, toward the house.
Moments later, however, he was once again walking in that slow purposeful long step toward the woods. This activity went on for over an hour: walking cautiously to the woods, then running back to the house. Finally, my curiosity got the best of me. I crept out of the house and followed him on his journey.
He was cupping both hands in front of him as he walked; being very careful not to spill(溅出) the water he held in them. Branches and thorns slapped his little face but he did not try to avoid them. He had a much greater purpose. As I leaned in to spy on him, I saw the most amazing site.
Several large deer appeared threatening in front of him. But Billy walked right up to them. I almost screamed for him to get away. And I saw a baby deer laying on the ground, obviously suffering from heavy loss of water and heat exhaustion, lift its head with great effort to lap(舔) up the water cupped in my beautiful boy’s hand.
I stood on the edge of the woods watching the most beautiful heart I have ever known working so hard to save a life. As the tears that rolled down my face began to hit the ground, they were suddenly joined by other drops... and more drops... and more. I looked up at the sky. It was as if God, Himself, was weeping with pride.What can be learned from Paragraph 1?

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress(紧张) levels and blood pressure in people—half of them pet owners—while they performed 5 minutes of mental arithmetic(心算) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quick to base line heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall—mostly with their dogs—and found it worth doing.The underlined word “subjects” refers to ______.

Just as the teacher hands out the spelling test, you see Jeff pull out a small piece of paper with a lot of small words on it. Jeff hides the note into his hand but soon takes it out again. While he's taking the test, you see him looking back and forth between the teacher and his paper. There's no mistaking it — he's cheating.
Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studied for the test or who were the true winners of a game.
Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test—unless the person cheats again.
Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.
Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can’t pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn’t a good idea.
If you were sick or upset about something the night before and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.
A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together. Talking about these problems and working them out will feel better than cheating.The author thinks that when kids cheat in class, _______.
| A．it is unfair to other people |
| B．it does harm to their heath |
| C．teachers should punish them |
| D．teachers shouldn’t stop them at once |
Some students like cheating mainly because _______.
| A．the material in the test is very difficult |
| B．they want to do better than the others |

| D．they have little time to study |
The fifth paragraph mainly tells us ______.
| A．cheating isn’t a good idea |
| B．why kids cheat in the test |
| C．some kids can’t pass the test without cheating |
| D．some kids don’t spend time studying |
We can learn from the passage______.

In the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to leave college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a combination of adopt and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic—and very emotional. A year later came our second adopted boy. Then followed Son No. 3. In 2003, I gave birth to another boy.
You can imagine how busy I became, raising four boys under the age of 8! Our home was a complete zoo—a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each term.
The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to give up, but I knew I should set an example for them to follow through the rest of their lives.
In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!
I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, but when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day. It’s a process. Remember: little steps add up to big dreams.When the author went to Howard University, her dream was to be ______.
| A．a writer | B．a teacher | C．a judge | D．a doctor |

I began working in journalism when I was eight. It was my mother’s idea. She wanted me to “make something” of myself, and decided I had better start young if I was to have any chance of keeping up with the competition.
With my load of magazines I headed toward Belleville Avenue. The crowds were there. There were two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible, making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY EVENING POST. When it was suppertime, I walked back home.
“How many did you sell, my boy?” my mother asked.
“None.”
“Where did you go?”
“The corner of Belleville and Union Avenues.”
“What did you do?”
“Stood on the corner waiting for somebody to buy a Saturday Evening Post.”
“You just stood there?”
“Didn’t sell a single one.”
“My God, Russell!”
Uncle Allen put in, “Well, I’ve decided to take the Post.” I handed him a copy and he paid me a nickel. It was the first nickel I earned.
Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address adults with self-confidence, and persuade them by saying that no one, no matter how poor, could afford to be without the Saturday Evening Post in the home.
One day, I told my mother I’d changed my mind. I didn’t want to make a success in the magazine business.
“If you think you can change your mind like this,” she replied, “you’ll become a good-for-nothing.” She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me.
My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied with my father’s plain workman’s life, determined that I would not grow up like him and his people. But never did she expect that, forty years later, such a successful journalist as me would go back to her husband’s people for true life and love.Why did the boy start his job young?
