For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants(污染物) can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.
People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building--green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.Generally speaking, indoor air pollution may be more harmful than the air outside because________.
| A．indoor air pollution can often make people seriously ill |
| B．there may be more harmful gases outside the buildings |
| C．the air indoors is polluted, which is very harmful |
| D．man-made building materials give off dangerous gases |
Some kind of indoor pollution can be found in _______.
| A．every modern house | B．every old house |
| C．all kinds of houses | D．all kinds of offices |
The indoor air pollution is caused by ______.
| A．the building way that the builders want to save energy |
| B．the man-made building materials and the limit of air-flow |
| C．the building things that are made of man-made materials |
| D．the limit of the flow of air between inside and outside |
The reason why we should use different kinds of plants to clean the air is that ______.
| A．plants can let out all kinds of pollutants indoors |
| B．plants may take in more oxygen which people need |
| C．plants can absorb all kinds of harmful indoor chemicals |
| D．plants can make our houses prettier and more healthy |
The Chinese Antarctica(南极洲)expedition(探险队)returned to Shanghai on March 20 following a month living on the ice. It was the first time Chinese scientists had visited the Amery Ice Shelf—the longest ice shelf in the world.
The team collected ice samples and data on temperatures, which are necessary for research on global warming.
So far, about 27 countries have visited Antarctica for scientific research. Although the living conditions are very hard, many scientists have to stay there for long periods of time. So, how do they manage their lives on the ice?
Well, during the summer, the temperature in Antarctica reaches about-20℃. It falls to about-60℃ in winter. So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes to protect them from the cold. These clothes include jeans, running shoes, jackets, long underwears, boots and woolen socks.
Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is-30℃. Natural protection such as facial hair can also help.
“That’s why many researchers wear a beard. It really does keep you warm，”says German explorer Arved Fuchs.
Usually, the polar researchers have good meals. Some even have feasts(盛宴)on holidays like Christmas and New Year’s Day. Vegetables are always welcome and usually finished the quickest.
Life on the ice means living with other researchers in tight living space. Most people sleep in dorm(宿舍)style rooms. More remote field camps use separate tents. So, at least some researchers don’t have to put up with annoying snorers(打鼾者)．
But what do they do for fun in their spare time? There are actually a lot of things they can do. They watch movies, read tons of books, listen to music, have saunas(桑拿浴)，paint and ski. Some female researchers might even do some knitting.
It is important for a polar researcher to be in good physical condition. They can be required to climb to heights of more than 3, 000 meters. And the Antarctic atmosphere has less oxygen than that of any other continent. In which month of this year did the Chinese Antarctica expedition mentioned in the passage reach the Amery Ice Shelf?
| A．February. |
| B．March. |
| C．January. |
| D．December. |
Why do some polar researchers wear beards? Because _______.
| A．they have no time to shave(刮脸)their beards |
| B．beards are helpful to keep warm |
| C．beards will come out soon when they are shaved |
| D．they think beards will make them look handsome |
The underlined phrase “put up with” probably means _______.
| A．hear |
| B．turn down |
| C．let out |
| D．suffer from |
Which of the following do you think is the most important one to a polar researcher?
| A．Clothes. |
| B．Meals. |
| C．Tents. |
| D．Health. |
The best title of the passage is _______.
| A．The Antarctica |
| B．The Chinese Antarctica Expedition Explored the Antarctica |
| C．Life in Antarctica |
| D．The Exploration of Antarctica |
Just 25 years ago, the top three career hopes for young people in Britain were teacher, banker and doctor. Now, they want to be sports stars, pop stars and actors, according to a survey by the Guardian newspaper.
Rachel, a character in the popular TV show Glee, may be said to speak for British teenagers. “Nowadays being nobody is worse than being poor.” He said.
Emma Brockes, a reporter with the Guardian, believes it is “the bad influence of celebrity(名人) culture” that is to blame.“When children wanted to be doctor, it wasn’t because they were really more interested in the functions of human organs than they are now; you go where the respect is.”She wrote.
It could explain why there has been such an increase in levels of anxiety and depression. Dr Carlo Stranger, of Tel Aviv University, studied the sense of self for his new book The Fear of Insignificance: Searching for Meaning in the 21st Century. He told the Daily Mail that young people now are “affected by the close connection to the global entertainment network, which has turned ranking and rating people according to wealth and celebrity into an obsession(痴迷).”
“As humans, we naturally measure ourselves to those around us, but now we live in a global village. We are comparing ourselves with the most ‘important’ people in the world and finding ourselves wanting…” he said. Today, even high achievers constantly fear that they are insignificant when they compare themselves to success stories in the media.
The way out? Simply stop measuring your achievement through a fantasy of wealth and celebrity. Dr Strenger said that it is a process called “active self-acceptance through a constant search for self-knowledge through life.”
“The fear of insignificance can only be overcome through strong individual and cultural identity over and above measurable achievement,” he said.Nowadays, young people in Britain want to _______.
| A．choose jobs based on interests |
| B．become famous |

Looking through a magazine in a waiting room recently, I came across an article with the title “My top five most precious possessions”．It was just a few lines of text with pictures, but it caught my imagination.
It’s interesting how inanimate(无生命的) objects can take on such significance and become woven into a person’s, and sometimes a whole family’s, life history.
Anyway, the article had me considering what my most precious possessions are.It was difficult to choose only five, but here are mine:
An old cardboard box filled with my children’s baby photos.
A yellow pocket-sized birthday book of special things (poems, pictures of flowers and trees, etc) given to me by my dad when I was probably about seven or eight years old.
A 21st Birthday card from my mum.In it she’s written her congratulations, her love, and her hopes for my future.She died not long after, when I was in my early twenties.
A few ancient but very beautiful botany books that were once my great grandmother’s.She was a botanist in a time when it was relatively unusual for women to be qualified in this field and I think she was probably a remarkable and very interesting woman.I’d like to have known her.
A brooch(胸针) left to me by my much-loved grandmother.It was given to my great grandmother (her mother) by my great grandfather on his return from World War Ⅰ.It is not worth anything in terms of money.However, it not only stands for a link between four generations of women, but it is also a reminder of one young man’s return from World War I.
How about you? I’d love to hear what you feel are your most precious possessions. What made the writer have the idea of writing the passage?
| A．Her love for her relatives. |
| B．Her rich imagination about the objects. |

Most kinds of rose plants come from Asia. But roses are also native to other areas including northwest Africa, Europe and the United States. In 1986, Congress chose the rose as American’s national flower. Technically, Congress and President Ronald Reagan declared it the “national floral emblem（国花）.” Whatever the name, the decision did not smell sweet to supporters of other popular flowers.
Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts. You should plant your roses where they can get sunshine for about six hours on bright days. You can buy roses from a garden center or by mail order. You can buy potted roses, also known as container roses, or bare-root plants. Each kind has its fans.
Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, an expert, points out that bare-root roses come without soil. So they weigh less to transport.
Another expert advises getting bare-root roses as close to planting time as you can.. If they arrive before you are ready to plant them, make sure the packing material is moist. Keep the plants in a cool, dark place. The resting plants have no leaves but still need water. When growing roses, the soil should feel moist deep down. Watering should be done in the morning.
But do not water too much. People often ask Jeffrey Dinslage about unhealthy discoloration on rose leaves. He says the spots are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch, the substance used to protect the roots, to improve the quality of the soil, temporarily from around the roots. This will help dry the soil.From the first paragraph, we know that in the United States _______.
| A．all the people like roses |
| B．there are a lot of national flowers |
| C．some roses don' t smell sweet |
| D．there are some other popular flowers |

Why does Jeffrey Dinslage suggest planting bare-root roses?
| A．They are easier to plant. |
| B．Their roots develop better. |

I’m Sorry, I Won’t Apologize
Almost daily，news reports include accounts of public figures or heads of companies being forced to say they're sorry. In a recent case，Marge Schott，managing partner of the Cincinnati Reds，at first did not want to apologize for her remark that Hitler "was good at the beginning but he just went too far. "Under pressure，she finally said that she regretted her remarks "offended many people". Predictably — and especially given her history with such comments — many were not satisfied with this response and successfully lobbied for her resignation.
This particular use of "I'm sorry" has a familiar ring. The other day my husband said to me，"I'm sorry I hurt your feelings." I knew he was really trying. He has learned，through our years together，that apologies are important to me. But he was grinning，because he also knew that "I'm sorry I hurt your feelings" left open the possibility — indeed，strongly suggested — that he regretted not what he did but my emotional reaction. It sometimes seems that he thinks the earth will open up and swallow him if he admits fault.
It may appear that insisting someone admit fault is like wanting him to humiliate himself. But I don't see it that way，since it's no big deal for me to say I made a mistake and apologize. The problem is that it becomes a big deal when he won't.
This turns out to be similar to the Japanese view. Following a fender bender，according to a Times article，the Japanese typically get out of their cars and bow，each claiming responsibility. In contrast，Americans are instructed by their insurance companies to avoid admitting fault. When an American living in Japan did just that — even though he knew he was to blame — the Japanese driver "was so incensed by the American's failure to show contrition that he took the highly unusual step of suing him."
The Japanese driver and I are not the only ones who are offended when someone obviously at fault doesn't just fess up and apologize. A woman who lives in the country told me of a similar reaction. One day she gave her husband something to mail when he went into town. She stressed that it was essential the letter be mailed that day，and he assured her it would. But the next day，when they left the house together，she found her unmailed letter in the car. He said，"Oh，I forgot to mail your letter." She was furious— not because he had forgotten，but because he didn't apologize.What was Marge Schott forced to do？
| A．To make a prediction of the future. |
| B．To say "Hitler was good at the beginning." |
| C．To say "Im sorry." |
| D．To count figures. |
The author felt _____ .

| A．admit it and apologize |
| B．avoid admitting it |
| C．wxplain it away |
