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?

Carl studied in our middle school three years ago. Last August his father found a job in another city and his family moved there. He began to study in the new school and we often write to each other. He often tells me something about the city where he lives now and his studies in the school. So I can know what happens to him.
Last Friday Carl came to our city again. He hoped to accompany(陪伴) his old grandpa during the summer holiday. He was taller and stronger than before. We swam in the river outside the city together and had a picnic on the island. It surprised me that he had learnt to cook when we were traveling in the wild forest. He told me his parents were both busy and sometimes he stayed at home and he had to look after himself.
“How do you like your school?” I asked.
“Wonderful,” said the young man.” It has a tall building and there ‘re two chemistry labs, two biology labs and three physics ones. And its library is big and there’re plenty of books in it.”
“I can see you are satisfied with it.”
“Yes,” he answered. “But our geography teacher often says it himself in class.”

A small town in Tasmania, an island off the south coast of mainland Australia, is making itself an environmental role model by becoming the country's first plastic bag-free town.
Since April 28, Coles Bay's population of 175 and its tourist shoppers have been using reusable paper or cloth bags to carry their shopping.
Ben Keamey, a local businessman who supports the bag ban, said it would cut the amount of waste and prevent damage to native wildlife that try to eat the plastic.
"Most businesses here come from the tourism and that's all based on the environment, so people were pretty supportive," he said.
Every year Australians use more than six billion plastic bags. More than half of these come from the supermarket. Since it takes years for the bags to biodegrade（生物递减分解）, tens of millions end up polluting the environment. They kill about 100,000 sea-birds and animals, which mistake bags for food, every year.
Only in the past few months have major Australian supermarkets begun cutting on their use of plastic bags. Environmental groups are pushing for a plastic bag fee like that in Ireland. There, since plastic bags cost 10 pence (about 1 yuan) each, their use has been cut by 90 per cent.
Pollution caused by plastic bags is a big headache for countries all over the world. As early as 1999, Beijing said that only plastic bags of certain thickness could be used. This was to encourage them to be used again and again, since an average of six million plastic bags are used there every there every single day.Which might be the best title for this passage?

People often hear each others' voices without ever seeing the faces they belong to. "Nowadays we are talking away on the phone without meeting people," says Seung-Jae Moon. And from business conference calls to chat lines, people often imagine they would recognize the speaker if they saw him or her. Seung-Jae Moon, a linguist of Korea found that, under certain conditions, they're actually right.
Moon decided to see just how close those mental pictures match up with reality and if there was any relation to how people speak rather than what they are saying. He recorded 16 Koreans, half men and half women, reading the same passage, and took a full-body photo and head shot of each speaker. Then he played the tapes for 361 Koreans and 173 Americans who did not speak Korean and asked his subjects to match up voice and picture. The Korean participants viewing full-body photos were quite perceptive. A majority linked 6 of the 8 women to the correct voice and did so for 5 of the 8 men. With the Korean group shown only faces, accuracy plummeted, but more than 20 percent of the subjects selected the same incorrect picture. The Americans showed no accuracy in matching the foreign voices to photos, but they too were consistent in their errors. That disconnection reveals conflicting ideas of physical and vocal beauty. Moon asked people to pick a favorite face and voice. Seventy percent of the Koreans picked one voice, but there was no agreement on a face. Americans didn' t agree on either count. And over 65 percent of both Koreans and Americans did not match their favorite face with their favorite voice.
Moon hopes to use software to break voices into components like pitch and hoarseness to narrow down which elements trigger certain mental pictures. "If we can map which characteristics of the voice triggers what kind of linage, and it doesn't matter whether that image is the right or wrong one of the actual speaker, then we can create an image through voice,' he says. That capacity could help to create computer-synthesized voices tailored to conjure up specific associations — audio books for children that inspire motherly visages, or warning alerts that bring to mind a stern police officer.People often think that they would ______ the speaker when they saw the speaker.
| A．understand | B．recognize | C．like | D．surprise |
Moon decided to do the experiment to ______.
| A．see how close mental pictures match up with reality |
| B．how people speak |
| C．see if there was any relation to how people speak rather than what they are saying |
| D．both A and C |
He asked ______ Korean women to speak and recorded their voices.

| C．The Korean women | D．The Americans |
______ percent of Koreans and Americans matched their favorite face with their favorite voice.
| A．Less than 65 | B．Less than 35 | C．Over 65 | D．About 20 |
As a teenager in 1972, Bill Gates boasted that he would be a millionaire by the time he was 20. While he did not quite achieve that goal, only 15 years later, he was a millionaire. And by 1992, as head of the Microsoft company, he became the richest man in America with assets（资产）of nearly US $ 6.3 billion.
Born in Seattle, Washington on 28, October, 1956, Gates was named William Henry after his father and grandfather. From the beginning, he was an extremely energetic and intelligent child. He had read the entire world book encyclopedia（百科全书）by the age of nine. His favorite subjects at school were science and math and his favorite pastime was "thinking".
Gates first started to play with computers at the age of 13. Before long he became an expert at working the school's computer. After his graduation from secondary school, Gates was accepted by the three top universities in the USA-Princeton, Harvard and Yale. He chose Harvard and began classes there the next autunm, majoring maths. But he was still obsessed（占据心里）with computers and spent as much time in the computer laboratories as he did in the lecture halls.
By 1975, Gates and a partner, Paul Allen, had developed a software program called BASIC. This was not the first program ever created, but its inventors were the first to decide that people who wanted to use it should pay for it.
BASIC was a success because until it came along, there had been no efficient way of getting computers to carry out instructions. Although he had not completed his degree, Gates left university and went to work full time for the new company he had formed called Microsoft.
His next project was the software program that made him famous and very rich. It was called DOS, short for Disk Operating System, and it was purchased by IBM in 1980. Today it is the operating system used in more than 14 million personal computers around the world.
As chief executive officer（首席行政长官）of Microsoft, Gates is known as a bright man, but one who is not easily satisfied. He is quick to criticize his staff and hates to be questioned about decisions he has made. He was regarded as a loner and unfashionable boring computer nut until his marriage to Microsoft manager Melinda French on New Year's Day 1994. Yet to many people now, Gates, is a person who is, in spite of his great wealth, humble（谦恭）and ordinary. He spends his money carefully. He eats in fast food restaurants and flies economy class. And when praised for Microsoft's great success, he has been heard to say, "All we do is put software in a box and if people see it in the stores and like it, they buy it."When he was a teenager, Bill Gates wanted to be a ______.
| A．teacher | B．doctor | C．businessman | D．professor |
When Gates went to Harvard, he ______.
| A．was only interested in maths |
| B．spent most of his time in computer laboratories |
| C．developed the first computer software program |
| D．divided his time between his maths studies and the computer laboratories |
Before the development of BASIC, ______.
| A．no one was interested in computer software |
| B．software programs were not considered commercial projects |
| C．software programs were very expensive |
| D．no one wanted to pay for computer software |
When the writer says "He was regarded as a loner and unfashionable boring computer nut", he means ______.
| A．Bill was so strong-minded that no one could change his mind |
| B．The only thing that could interest Bill in his life was computer |
| C．Bill was such a boring young man that nobody would like to talk to him |
| D．Bill couldn't work out the boring computer programs |
Most people think that Bill Gates is ______.
| A．a crazy person | B．a person obsessed with making money |
| C．someone who spends money freely | D．a quite common, normal person |
Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to memorize some facts or a formula(公式). It is actually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a math problem. Great scientists before us didn’t get everything from school .Their teachers only showed them the way. Edison did not even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school . They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all , they knew how to use their brain.To work out a math problem, you need to know __________.
| A．only a certain formula |
| B．how to memorize some facts |
| C．only some facts |
| D．the method to work it out |
Why were many scientists so successful?
| A．They received good education. |
| B．They were very clever. |
| C．They knew how to learn. |
| D．They learned lots of facts and formulas. |
How did great scientists study?
| A．They read a lot of books and asked many questions while reading. |
| B．They did thousands of experiments. |
| C．They always worked hard and never wasted time. |
| D．All of the above. |
