Apparently，we are safe neither at home nor in the business office．We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects．These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house．They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines．As the water is moving．these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

Now 23，Ye Dong got his diploma in June 2010. But he has barely left the campus. He still eats in the canteens and studies in the classrooms. Living close is convenient and familiar, he said.
Around almost every college and university in China are cheap apartments and bungalows for rent, where lots of graduates like Ye live. They live and look like enrolled students, but they aren't. Such kind of graduates is called “school-drifters “. It became a popular search keyword and triggered wide media coverage and further academic research.
“The number is increasing over the years. A simple reason is that each year the number of graduates rises, while the employment rate remains basically the same. A large portion of the unemployed become school-drifters. Some previously employed also come back after a short, unsatisfying work experience.”according to Hu Jiewang, a sociology professor at Jiaying University in Guangdong province.
Ye landed a job as a production assistant in a local jewelry company in March last year but quit two months later. " The 2，400-yuan($360) a month salary was high among my classmates, but the job was too tiring. I had only one day off every week and the working hours were too irregular, “he said.” Entering society made me feel hollow. "
Hu said most of the school-drifters aim to enter grad school. Some hope to find a better job ； some want to stay in big cities ； and some are simply fearful of the intensely competitive job market.
" Living on school resources " ，Hu said, " is a way of cutting living costs. But they do have some resource conflict with currently enrolled students”.
Why don't drifters return home? " From ancient times the Chinese have had the notion that ‘ going out’ and ‘ going to colleges' were good. Anybody coming back home without achievements is a loser, “Hu said.
After graduation and entering society, many graduates felt lost. As a result, the number who stayed in school——for further education, for better opportunities, or for the comfort——increased. " School-drifters” are a group of university students who _________.
| A．have dropped out but wouldn't leave the campus |
| B．have finished school but wouldn't leave the campus |
| C．have finished school but haven't got their diplomas |
| D．haven't passed their Graduation Exams |
Why did Ye abandon his job in a local jewelry company?
| A．He was too lazy. |
| B．He wasn't pleased with the job. |
| C．The salary was low. |
| D．The jewelry company was very good. |
As " school-drifters " ，they can _________.
| A．reduce their expenses | B．make more friends |
| C．decrease pressures | D．make more money |
The passage is mainly about _________.
| A．a new social phenomenon |
| B．an event taking place in the campus |
| C．how to deal with “school-drifters” |
| D．“school-drifters “are hated by people |
In American high schools, there is a tradition for each year's graduating class( called the seniors) to play a joke on the school—the Senior Prank(毕业恶作剧）.
This usually happens at the end of the school year just before the seniors graduate from the school. It is an unofficial tradition. Al-though the schools don't encourage it, each year the seniors try to make their pranks the most original so that their class will be remembered in the years to come. The joke is supposed to be light-hearted(无伤大雅的）and must not do major damage to the school property .
The best prank at my high school was done several years ago. A flower called the golden poppy(金罂粟花）is the state flower of California ； the state law states that no one can cut them down once they are planted.
The seniors at my school took advantage of the law. They planted golden poppies all over the football field one night, spelling out their graduation year with the flowers ！ Since the school couldn't break the law to cut down the poppies, they had to wait until the flowers died.
The greatest prank that I've ever heard was done by one of my history teachers when he was in high school. He and some of his close friends went fishing in hopes of catching big fish for their prank. They were lucky and caught a three-foot shark.
My teacher and his friends took the shark to the school at night and dumped it into the swimming pool. The next morning when students went swimming, they found a dead shark in their pool. The chlorine(氯）in the water had killed the shark ！ My history teacher always regretted that his school had put so much chlorine in the pool, or it would have been more fun if the shark was still alive the next day.
The schools won't take it seriously if the pranks don't cause too much damage. But, sometimes the school will punish the seniors for going too far with their prank. My teacher's “Shark Prank “is an example of a prank gone too far. The school had to drain (排水）the pool and have it cleaned before filling it up again, which had cost the school several thousand dollars. The underlined word “property “means _________.
| A．资产 | B．性质 | C．道具 | D．所有权 |
The author implies (暗示）_________.
| A．the schools encourage the seniors to play the prank |
| B．his history teacher was punished by the school |
| C．the law of California doesn't allow planting the golden poppy in the campus |
| D．after finding a shark in the swimming pool, the school killed it with the chlorine |
We can infer(推断）from the passage that _________.
| A．the “Golden Poppy Prank “is successful and well-meaning |
| B．the Senior Prank is an unofficial tradition |
| C．the school had to cut down the golden poppies at last |
| D．the golden poppy is the state flower of California |

A locavore is someone who eats foods produced locally. Locavores usually define local as within 160 kilometers. Local is a popular word these days in food advertising. Farmers markets are also popular. These are often held once a week, usually in a big outdoor space. And some people grow their own food at home or in community gardens.
Locally grown food can cost more but locavores find it more satisfying. Not just the taste, but the fact that they are supporting local producers. And some believe eating local foods is healthier. This may be true in terms of freshness, but it also depends on how the food was produced. Restaurants are also joining the local food movement. And local food is involved in another movement—" slow food " ，whose aim is to honor the tradition of foods prepared and enjoyed with time and care, like a fine wine.
The city of Sonoma, California, is getting in the spirit of the local food movement. The city is located in the wine-making Sonoma Valley. Next week, the City Council is expected to approve changes to make it easier to raise chickens and rabbits on smaller properties.
No one is sure how many people want to. But anyone with a single family house and a fenced backyard could keep as many as sixteen chickens and eight rabbits. Larger properties could have more. Either way, a permit and inspection would be required.
Residents could sell eggs but not meat. City officials did re-search about other places with similar rules. They learned that people often end up giving their chickens names and treating them like pets.
If the happens, Sonoma residents will have no trouble finding boy names for roosters. Under the proposed new rules, the city will not permit any roosters other than those now living there. City officials want to avoid early morning wake-up calls for the neighbors. As one Sonoma official explained：”You don't need a rooster to have eggs." The best title of the passage is that _________.

| D．Locally grown food can cost more |
The advantage of eating locally grown food is _________.

| A．a permit and inspection would be required |
| B．residents could sell eggs but not meat |
| C．city officials did research about other places with similar rules |
| D．people often end up giving their chickens names and treating them like pets |
Not everyone can become a professional basketball or football player. Not everyone, especially youth living in the city, has access to large green fields. But kids still want to compete. So all over America, young people started skateboarding and bicycling. This is where the Extreme Games, or X-Games, started.
The X-Games are beautiful to watch. They simply defy gravity. Riders fly down ramps on skateboards and do crazy tricks in the air. The X-Games have become so popular that this year BMX cycling is the newest sport in the Beijing Olympics. You will see competitors descend a 25-foot (8 meters) ramp, the highest in the world, as they race through a wild obstacle course.
But the X-Games are more than sports. They have become a culture. Fans of the X-Games have rejected the mainstream. They wear certain clothes, listen to different music and live life to the fullest.
It is not unusual to see young people riding a skateboard or showing off their cycling tricks in a park. Extreme sports arrived in China in the late 1990s. The Chinese Extreme Sports Association was established in 2004
