If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don’t be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows.
Approximately(大約) the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11 mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus(VS) 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone."
More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported initiating a phone call. That's not all, however. What goes on behind the walls of the stalls(小隔間) is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom — 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues.
As expected, Gen Y(1981年后出生的一代) respondents(調查對象) are the pacesetters(先導者) in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers(1946-1965) and 47 percent of the Silent Generation(1925-1945).
While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom – 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall.
"The writing is on the stall," said 11 mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private."
In the process, high-tech hygiene(衛(wèi)生) is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent said they wash their phones.

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有彈性的) to hard and glasslike.
Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障礙).
Two types of chemicals in particular have raised special concern lately. They are called phthalates (鄰苯二甲酸鹽) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (爭議). That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化劑) are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (滲透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.
【小題1】What can we know about the plastic from the first paragraph?
| A．Its characters and effects. | B．Its wide use and bad points. |
| C．Its importance and chemicals. | D．Its popularity and advantages. |
| A．A soft plastic cup. | B．A pencil eraser. |
| C．A baby milk bottle. | D．A new perfume. |
| A．through mouth or nose | B．through blood transfusion |
| C．by feeling plastic products | D．by heating in the microwave |
| A．A new ban on plastic products. | B．Problems caused by the plastic. |
| C．Good points of the plastic. | D．The use of plasticizers. |

In a recent study, researchers have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, make the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use. Combining all the energy input totals for treatment and distribution, researchers found that producing bottled water requires between 5.6 and 10.2 million joules(焦耳) of energy per liter, depending on transportation factors. That's up to 2, 000 times the energy required to produce tap water.
To break down the energy requirements, researchers found that producing the plastic bottles and transporting the bottles greatly dominated(控制) the energy input. Although some companies are experimenting with producing lightweight bottles or using recycled materials, the researchers calculated that the manufacturing cost is about 4 million joules of energy per plastic bottle weighing 38 grams, and the cap weighing 2 grams.
“Our previous work had suggested that bottled water production was an energy intensive process, but we were surprised to see the results, ” the researchers said.
Transportation costs vary depending on the distance and mode of transport and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US:” spring water” which comes from an underground spring and “purified water”,which is city tap water that has received further treatment. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck requires about 4 million joules per liter for transportation. For the spring water, the transportation energy equaled (in the case of Fiji) the energy required to produce the bottle.
With this data, the researchers hope that future studies will have the ability to make specific estimates for different situations, and possibly find ways to cut energy costs.
【小題1】From the first Paragraph we can know that the energy required to ______.
| A．produce bottled water includes the energy required to drink it |
| B．distribute bottled water includes the energy for producing the bottles |
| C．distribute bottled water is much smaller than the energy for treating it |
| D．produce bottled water is much smaller than the energy for producing tap water |
| A．to fill tap water into the plastic bottles directly |
| B．to replace the plastic bottles with metal containers |
| C．to produce lightweight bottles with recycled materials |
| D．to use bicycles to transport and deliver bottled water locally |
| A．Treatment of bottled water needs no energy input at all. |
| B．Bottled water production is an energy intensive process. |
| C．Transportation of bottled water takes up the most energy input. |
| D．Production of the plastic bottles greatly dominated the energy input. |
| A．there are two main kinds of bottled water in the US |
| B．world consumption of bottled water has been increasing |
| C．transportation costs have something to do with the mode of transport |
| D．bottled water produced in Spring is more expensive than purified water |
| A．To help consumers themselves make more environmentally sustainable choices. |
| B．To advise the government to take severe measures to stop producing bottled water. |
| C．To urge the consumers to drink tap water instead of bottled water for the sake of the earth. |
| D．To try the best to find ways to produce bottled water cheaply and quickly for the companies. |

We can stay young forever. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging.
His solution is a herbal medicine to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has
taken a hint from its aging process. It is responsible for the level of activity that the human bodies go through Studies conducted by Dr.Shen show that herbal medicine based on the shen system slow the the ancient Chinese medicine system called “shen”.
According to Shen, it is the kidney（腎臟）which adjusts the functioning of the body as well as aging process, says a report in The Telegraph newspaper.
We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness in general, and wrinkles, among others. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young?
This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
【小題1】How did Dr. Shen find the solution to the problem of aging?
| A．By studying Western medicine. |
| B．By learning traditional Chinese medicine. |
| C．By combining both Western and Chinese medicine. |
| D．By doing research on both Western and Chinese people. |
| A．Medical treatment. | B．People’s good kidney. |
| C．Level of people’s activity. | D．Positive life attitude. |
| A．their bodies produce T-cells |
| B．their bodies are unable to fight diseases |
| C．they have reduced strength, loss of hair |
| D．they become weaker and weaker |
| A．producing more low calorie food allows people to keep young |
| B．the more Chinese herbal medicine people drink, the better for health |
| C．people should try to quicken the production of T-cells in the body |
| D．it remains unknown how effective Dr. Shen’s herbal medicine is |

If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (氣泡) accumulate in a joint, is sharp pain and a bent body — thus the name. If the bubbles form in his lungs or brain, the consequence can be death.
Other air-breathing animals also suffer this decompression (減壓) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs (魚龍). That these ancient sea-animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil(化石)bones that have caved in on themselves are thus a sign that the animal once had the bends.
Bruce Rothschild of the University of Kansas knew all this when he began a suty of ichthyosaurs bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompession over the 150 milllion years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Trassic period and from the later Jurassic and Cretaceous periods.
When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before the died, but not a single Trassic specimen showed evidence of that sort of injury.
If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly — and, most strangly, they lost it afterwards. But that is not what Dr Rothchild thinks happened. He suspects it was evolution in other animals that caused the change.
Whales that suffer the bends often do so because they have sufaced to escape a predator (捕食動物) such as a large shark. One of the features of the Jurassia oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaurs lunches. Trassic oceans, by contrast, were mercifully shark-and crocodile-free. In the Trassic, then, ichthyosaurs were top of the food chain. In the Jurrasic and Cretaceous, they were prey (獵物) as well as predator —and often had to make a speedy exit as a result.
【小題1】Which of the following is a typical symptom of the bends?
| A．A twisted body. |
| B．A gradual decrease in blood supply. |
| C．A sudden release of nitrogen in blood. |
| D．A drop in blood presure. |
| A．how often ichthyosaurs caught the bends |
| B．how ichthyosaurs adapted to decompression |
| C．why ichthyosaurs bent their bodies |
| D．when ichthyosaurs broke their bones |
| A．confirmed his assumption | B．speeded up his research process |
| C．disagreed with his assumption | D．changed his research objectives |
| A．failed to evole an anti-decompression means |
| B．grdually developed measures against the bends |
| C．died out because of large sharks and crocodiles |
| D．evoled an anti-decompression means but soon lost it |

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.
【小題1】Not enough sleep can cause obesity by ______.
| A．burning more of your energy |
| B．making you want to eat more food |
| C．keeping you from doing exercise |
| D．helping you feel great without food |
| A．have your ghrelin level rise and leptin level drop |
| B．have your leptin level rise and ghrelin level drop |

When Scotsman Alexander Graham Bell invented the telephone in 1876, it was a revolution in communication． For the first time, people could talk to each other over great distances almost as clearly as if they were in the same room． Nowadays, though, we increasingly use Bell' s invention for taking photographs, accessing the internet, or watching video clips, rather than talking． Over the last two decades a new means of spoken communication has appeared: the mobile phone．
The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modem mobile handset． Within a decade, mobile phones became available to the public． The streets of modem cities began to feature sharp-suited characters shouting into giant plastic bricks． In Britain the mobile phone quickly became the same with the "yuppie" , the new type of young urban professionals who carried the expensive handsets as status symbols． Around this time many of us said that we would never own a mobile phone．
But in the mid-90s, something happened． Cheaper handsets and cheaper calling rates meant that, almost overnight, it seemed that everyone had a mobile phone． And the giant plastic bricks of the 80s had changed into smooth little objects that fitted nicely into pockets and bags．
Moreover, people' s timekeeping changed． Younger readers will be amazed to know that, not long ago, people made spoken arrangements to meet at a certain place at a certain time． But later Meeting times became approximate under the new order of communication: the Short Message Service （SMS） or text message． Going to be late? Send a text message! It takes much less effort than arriving on time, and it' s much less awkward than explaining your lateness face to face and the text message has changed the way we write in English． Traditional rules of grammar and spelling are much less important when you' re sitting on the bus, hurriedly typing "Will B 15mm late - C U @ the bar． Sorry! - ）"．
Alexander Graham Bell would be amazed if he could see how far the science of telephony has progressed in less than 150 years．If he were around today, he might say "That' s gr8! But I' m v busy rite now．Will call U 2nite．"
【小題1】What does the underlined part in Para． 2 refer to?
| A．Houses of modern cities． | B．Sharp-suited characters． |

When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.
Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat.”
Researchers have agreed that today’s dog is the result of the domestication(馴化) of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendents(后代) of which now live with people in Alaska, Canada, and the Lower 48.
Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永凍層) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.
Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(標本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.
Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep,” Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource.”
【小題1】 The underlined word “remains” is closed in meaning to ______.
| A．leftover food | B．a(chǎn)nimal waste |
| C．dead bodies | D．living environment |
| A．a(chǎn)ncient dogs entered North America between 1450 and 1675 AD |
| B．the 11 bones of ancient dogs are not from native American dogs |
| C．the bones discovered by the gold miners were from North American wolves |
| D．the bones studied were not from dogs brought into North America by Europeans |

Monitoring global warming usually requires a Ph. D. and enough maths to glaze your eyes. But that Francisco Lopez and Ruby Nostrant track（記錄）what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming,” Ruby explained.
Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It’s a research project that the average person, even a kindergartner, can join in.
The National Phenology（生物氣候學）Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states.
“All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin. He calls the volunteers “citizen-scientists.”
The idea is that tracking flowers blooming—especially lilacs（丁香）; which everyday people have helped track for decades—is fairly simple. The Website http://www.Windows.ucar.edu/ citizen_science/budburst/index.html gives directions on what to look for in different parts of the country.
University of Maryland professor David Inouye said it’s so easy to figure out what’s blooming that a lack of special knowledge isn’t a problem.
University of Arizona ecology graduate student Lisa Benton coordinated（協(xié)調）the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she’s been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out.
“I like going out in the desert,” he said. “I want to be an Einstein.”
【小題1】Francisco Lopez and Ruby Nostrant are monitoring global warming by __________.
| A．watching early spring blooms and changes in animals |
| B．studying the biological timing of earth |
| C．collecting data of the local weather |

| A．ecology college graduates | B．high school students |
| C．common people | D．experts |
| A．the study carried out by students is convincing |
| B．the students still need special training to study climate change |
| C．it is difficult to study climate change |
| D．to figure out what’s blooming needs special knowledge |

| C．Francisco Lopez. | D．Jake Weltzin. |
| A．changes in animals caused by global warming happen earlier than those in plants |
| B．the biological timing of earth is changing because of climate change |
| C．the effect of climate change in Tucson, Arizona can be hardly noticed |
| D．a(chǎn)ll the plants in Tucson, Arizona are blooming earlier because of climate change |
