It was once thought that air pollution 
affec
ted only the area immediately around large c
ities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（灾难的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.As pointed out at the beginning of the passage, people used to think that air pollution ______.
| A．caused widespread damage in the countryside |
B．affected the entire eastern half of the United States |
C．al most brought worldwide effect |
| D．existed merely in urban and industrial areas |
As far as the greenhouse effect is concerned, the author _____________.
| A．shares the same view with the scientists |
| B．is uncertain of its occurrence |
| C．rejects it as being ungrounded（无根据的） |

It can be inferred from the passage that .
| A．raising the world’s temperature a little would not do much harm to life on the earth |
| B．lowering the world’s temperature a little would lead to agricultural disasters |
| C．almost no temperature variations have occurred over the past decade |
| D．the world’s temperature will remain stable forever |
This passage is primarily concerned with .
| A．the greenhouse effect in the world |
| B．the measures to adjust the climate |
| C．the potential effect of air pollution |

WASHINGTON—Laura Straub is a very worried woman. Her job is to find families for French teenagers who expect to live with American families in the summer.
It’s not easy, even desperate.
“We have many children left to place: 40 out of 75,” said Straub, who works for a Paris-based foreign exchange programme called LEC. When exchange programmes started 50 years ago, family life was more accommodating. For one thing, more mothers stayed home.
But now, increasing numbers of women work outside the home. Exchange-student programmes have struggled in recent years to sign up host families for the 30,000 teenagers who annually come from abroad to spend their academic year in the United States, as well as the thousands more who participate in summer programmes.
School systems in many parts of the US, unhappy about accepting non-taxpaying students, have also strictly limited the number of exchange students they accept. At the same time, the idea of hosting foreign students is becoming less exotic.
In searching for host families, who usually receive no pay, exchange programmes are increasingly broadening their appeals to include everyone who has the ability to do it.
“We are open to many different types of families,” said Vickie Weiner, eastern regional director for ASSE, a 25- year-old programme that sends about 30,000 teenagers on academic year exchange programmes worldwide.
“For elderly people, exchange students keep us young; they really do!” said Jean Foster, who is hosting 16-year-old Nina Porst from Denmark.Vickie Weiner is the person who ________.
| A．works for a programme called LEC |
| B．works for a programme called ASSE |
| C．is 25 years old |
| D．hosts foreign students |
From the passage we can learn that at the beginning of the exchange programmes_______.
| A．all the families could host foreign students |
| B．only young couples could host foreign students |
| C．only those who were retired could host foreign students |
| D．those who were not too old could host foreign students |
Which of the following is the best title of this passage?
| A．US Struggles to Find Host Families |
| B．Idea of Hosting Students Is Different |
| C．Foreign-exchange Program Is Going On |
| D．Exchange Students Keep Old People Young |
All around the world, shoppers flock to Wal-Mart to buy everything. In Texas, they come for another reason: to see the wind turbine（涡轮机）, which supplies 5% of the store’s electricity. It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant.
The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods. It throws its weight behind environmental responsibility, and the impact could be amazing. “One little change in product packaging could save 1, 500 trees,” says Wal-Mart CEO Lee Scott．“If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference.”
Scott wants Wal-Mart to do its part too. He has promised to cut the existing greenhouse-gas emissions（排放）over the next few years and promised to construct new stores that are more efficient. He wants Wal-Mart’s fleet of more than 7, 000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they’re cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it’s working with consumer-product manufacturers to reduce their packaging and will reward them if they do so.
Some people may doubt it is a bid to attract attention from Wal-Mart’s controversial labor and health-insurance practices. But it’s not just window dressing, because Wal-Mart sees profits in going green. Scott says, “This is a business philosophy, not a social philosophy. We don’t go where we don’t think there’s a great interest in change.”
Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart’s image at a time when his company’s reputation is declining. He acknowledges that he launched the plan partly to shield （保护）Wal-Mart from bad press about its contribution to global warming. “By doing what we’re doing today, we avoid the headline risks that are going to come for people who did not do anything,” he says. “At some point businesses will be held responsible for the action they take.” Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit. We can infer from the passage that ______.
| A．Lee Scott is Wal-Mart’s CEO |
| B．there are 5, 200 stores in the world |
| C．Wal-Mart has a great influence on the world market |
| D．Wal-Mart has more than 7, 000 trucks all over the world |

| B．Wal-Mart’s green activity is just window dressing. |
| C．Wal-Mart aims to solve its health-insurance practices. |
| D．Wal-Mart doesn’t have any social responsibility at all. |
What will Wal-Mart probably do in the future?
| A．Reduce air pollution in its present stores. |
| B．Give favorable treatment to its consumers. |
| C．Ask the factories to reduce their packaging. |
| D．Demand the fleet of trucks to use more fuel than before. |

I really hadn’t meant to yell at them. But that grey afternoon saw it just as my son and daughter were making a terrible mess on the floor in the kitchen.
With a tiresome report to write, I felt bothered at my desk. Suddenly, it occurred to me that my kids were at fault. A voice inside me insisted that I do something quickly.
“Ok, you two here, what an awful thing you are attempting!” I was shouting angrily. I made for them, while it became evident that the boy wanted no part of me. “Get away from us!” he shouted back, there being an expression of support from his sister.
All of a sudden, I found the fault in myself. Quickly I shaped my hands into pincers(钳子) and crawled towards them, “Crabby（暴躁的） Daddy is here. Ha, Ha, Ha, he likes to yell at children, and then eat them!” My son continued to keep me away, but now he was laughing and crying at the same time. My mission to repair the damage caused by my yelling seemed to work well. Still, I regretted not having controlled myself first in a right way.
Need I let them know how badly they were acting by blaming? This is a lesson that serves myself. It only shows just how to get rid of something (ill-feelings, responsibility…) by blaming others. It’s not my “best self”.
We have to search for our “best self” when with our children. They don’t need perfect parents, but they do need parents who are always trying to get better. Here, I am reminded of the words of a great thinker. “When a man lives with God, his voice shall be as sweet as the murmur of the brook (stream)…” Then, in our lifetime, couldn’t we always speak to our kids in such a sweet voice since most of us consider them as the most precious in the world? And before we reach this level, what should we do when we come across various difficult cases with our children? Which of the following made the author aware of his fault?
| A．No obvious reason. | B．The boy’s yelling back. |
| C．His self-awareness. | D．The girl’s shouting back. |
According to the passage, the author will _________ in another similar situation.
| A．play a crab again like this time | B．apologize to kids in a sincere way |
| C．avoid blaming kids in a hurry | D．beat them up about such things |
What will the writer go on to write about in the next paragraph(s)?
| A．How to behave ourselves properly when kids are at fault. |
| B．How to play with our children in a more interesting way. |
| C．How to deal with the housework with children around us. |
| D．How to persuade children to do what they are told to. |
What does “the boy wanted no part of me” in the third paragraph mean?
| A．The boy was happy because I loved them. |
| B．The boy was curious because I wanted to help them. |
| C．The boy was very happy for I was angry. |
| D．The boy didn’t want me to join them. |
Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.
The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.
In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms—the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?
Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.
In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door. The first two paragraphs were written to show that ____.
| A．ancient Egyptian emperors were cruel |
| B．the Pyramid of the Sun is an unusual historic building |
| C．construction workers led a hard life in ancient Egypt |
| D．the secrets of the pyramids remain to be uncovered |
What is the purpose of making some secret doors to the pyramids? _______.
| A．To try to unlock some of its secrets |
| B．To stop robbers from finding the treasures inside |
| C．To refuse some visitors all over the world into it |
| D．To tell the truth to the people in the future |
Which of the following is NOT true to the Great Pyramid of Khufu? ______.
| A．It is the largest pyramid in the world. |
| B．It is the only one of the ancient wonders that is still standing. |
| C．Abdullah AL Manum took the King’s mummy and his treasures away |
| D．Scientists found a mysterious locked stone door to the Great Pyramid |
What would be the best title for the text?
| A．The Pyramid of the Sun |
| B．The Great Pyramid of Khufu |
| C．A Mysterious Locked Stone Door |
| D．Unlocking the Doors of History of the Pyramid |
“Yes, I’ll be ready at nine in the morning. Goodbye, dear, and thanks again.” It had not been an easy telephone call for Mrs. Robson to make. Her daughter had been very kind, of course, and had immediately agreed to pick her up and drive her to the station, but Mrs. Robson hated to admit that she needed help. Since her husband died ten years ago, she had prided herself on her independence. She had continued to live in their little house, alone.
This evening, however, she was standing at her living-room window, staring out at the SOLD notice in the small front garden. Her feelings were mixed. Of course, she was sad at the thought of leaving the house, as it was full of so many memories. But at the same time she was looking forward to spending her last years near the sea, back in the little seaside town where she had been born. With the money from the sale of the house, she had bought a little flat there. She turned from the living room window, and looked round at the room. One or two pieces of furniture remained, covered with sheet. All her pictures had been taken from the walls. There was a small fish tank, with two goldfish in it. When asked why, her husband used to say: “It’s nice to have something alive in the room.” Since he had passed away, she had always kept some goldfish, and always had “something alive in the room”.
The next morning, as her train was pulling out of the station, Mrs. Robson called to her daughter, “Kate, you won’t forget to collect the goldfish, will you? The children will love them. It’s…”
“I know,” Kate interrupted gently. “It’s nice to have something alive in the room.” But in the little house, the two goldfish had stopped their circling. They were floating on the water, in the room with silent walls.According to the passage, we know that Mrs. Robson ________.
