Following some of the tips for green living helps save our planet. All of these involve just a few changes to our daily habits.
Just walk and limit the use of your car. One of the poster images of pollution is our vehicles. It burns fuel. It is not as efficient as we hope it could be, and we use it every single day. To lessen the effects of the air pollution caused by our vehicles, we should limit their use. If we can walk to our destination then just let us go. Not only do we lessen our carbon dioxide emissions, but we also get a good exercise out of it.
Use a laptop instead of a computer desktop. Laptops are more energy efficient compared to their bigger counterparts. A laptop is generally 50 percent more efficient in using electricity. Aside from that there are other benefits of a laptop. It is portable so you can work anywhere you like and that you get powerful features without the large size of desktop units.
Turn off the faucet while you are brushing your teeth. It is always a better idea to use a glass when we are brushing our teeth and not to just let the faucet keep on running. Therefore，there is less water to waste while we are cleaning our pearly whites. Simply turn off the faucet when you are not using it.
Make good use of natural light. We have a great and natural lamp --- the sun, and we should learn how to take full advantage of it during daytime. So instead of turning on our lights or lamps even if it is still not evening, we should pull up the drapes and let the natural light come in from the windows.
These are just some of the best tips for green living, but of course there are still many of these tips if you just search for them. But you can do your own variation any time just always prioritize how you can use less energy and produce even lesser trash and pollution.What’s the best title for the passage?

Sam, an unemployed piano tuner, said it was only the second thing he had ever won in his life. The first thing was an Afghan blanket at a church raffle when he was 25 years old. But this was much bigger: it was $120,000! He had won the Big Cube, a state lottery game. To win, a contestant must first guess which number a spinning cube will stop on. The cube has six numbers on it: 1X, 10X, 50X, 100X, 500X, and 1000X. If he is correct, the contestant must then guess which of two selected variables is going to be greater. So, just guessing which number appears on the cube does not guarantee that you will win any money. Sam correctly guessed 1000X, but he still had to choose between two variables. One variable was the number of cars that would run the stop sign at Hill Street and Lake Avenue in six hours. The other variable was the number of times that a teenage boy would change TV channels in a three-hour period. This was a tough decision.
Finally, Sam flipped a coin. It came up heads, so Sam picked the teenager. He picked right. The stop sign was run only 76 times, but the teen clicked 120 times. Sixty-year-old Sam jumped for joy, for he had just won 1000 times 120, or $120,000. Sam dreamily left the lottery studio. Talking excitedly on his cell phone while crossing the street, he got hit by a little sports car.
Sam is slowly getting better. He was in the hospital for a month. His hospital bill was $110,000. And the insurance company for the little sports car's owner sued Sam for $9,000 worth of repairs. Also, Sam still has to pay federal taxes on his winnings. Sam doesn't play the state lottery any more. He says it's better to be unlucky.

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet（彗星）. When the fragment（碎片）landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our plant, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth’s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won’t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs（恐龙）were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn’t survive in the cold climate that followed and they became extinct. Will we meet the same end?Which of the following is NOT TRUE according to the author’s description of the disaster in 2094?
| A．The whole world becomes extremely cold. |
| B．All the coastal cities in African are destroyed. |
| C．The whole mankind becomes extinct. |
| D．The visit of the comet results in wars. |
Why does the author mention dinosaurs at the end of the passage?
| A．Because they could only live in the warm climate. |
| B．Because they once ruled the Earth. |
| C．Because their extinction shows future disasters. |
| D．Because dinosaurs and humans never live in the same age. |
In writing the passage, the author intends to_________.
| A．give an accurate description of the possible disaster in the future |
| B．prove that humans will sooner or later be destroyed |
| C．tell the historical development of the Earth |
| D．warn of a possible disaster in the future |

One evening after dinner, Mr. and Mrs. Tisich called a family meeting. “We’ve had to make a difficult decision,” Mr. Tisich announced. “You see, your mother has been offered a post as co-director of a television station in Chicago. Unfortunately, the station is not here. After thinking long and hard about it, we’ve concluded that the right decision is to move to Chicago.” Marc looked shocked, while his sister Rachel breathlessly started asking when they’d be moving. “It’s surprising, but exciting!” she said. Marc simply said, “We can’t go—I can’t leave all my friends. I’d rather stay here and live with Tommy Lyons!”
The Tisichs hoped that by the time they moved in August, Marc would grow more used to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings. When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyon’s house, but Mrs. Lyons said she hadn’t seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly.
What they didn’t know was that Marc had started walking over to Tommy’s house, with a faint idea of hiding in Lyons’s attic(阁楼) for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood: the fence that he and his mother painted, the tree that he and his sister used to climb, the park where he and his father often took evening walks together. How much would these mean without his family, who make them special in the first place? Marc didn’t take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons(纸板箱)the right size to hold his record collection.The conflict(冲突) in this story was caused by_________.
| A．Marc and Rachel’s different attitudes |

| A．he did not want to be left behind |
| B．he realized his family was important to him |

| D．he wished to be a more responsible person |
What would most likely happen next?

When I learned that my 71-year-old mother was playing Scrabble – a word game – against herself, I knew I had to do something. My husband suggested we give her a computer to play against. I wasn’t sure my mother was ready for it. After all, it had taken 10 years to persuade her to buy an electric cooker. Even so, we packed up our old computer and delivered it to my parents’ home. And so began my mother’s adventure in the world of computers.
It also marked the beginning of an unusual teaching task for me. I’ve taught people of all ages, but I never thought I would be teaching my mother how to do anything. She has been the one teaching me all my life: to cook and sew; to enjoy the good times and put up with the bad. Now it was my turn to give something back.
It wasn’t easy at the beginning. There was so much to explain and to introduce. Slowly but surely, my mother caught on, making notes in a little notebook. After a few months of Scrabble and other games, I decided it was time to introduce her to word processing(文字处理). This proved to be a bigger challenge to her, so I gave her some homework I asked her to write me a letter, using different letter types, colors and spaces.
“Are you this demanding with your kindergarten pupils?” she asked.
“No, of course not,” I said. “They already know how to use a computer.”
My mother isn’t the only one experiencing a fast personal growth period. Thanks to the computer, my father has finally got over his phone allergy(过敏反应). For as long as I can remember, any time I called, my mother would answer. Dad and I have had more phone conversations in the last two months than we’ve had in the past 20 years.What does the author do?
