Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon (峡谷) when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region.
Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (啮齿目动物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
“This is a huge find,” says Rick Greenwood, a scientist studying the site. “I don’t think most people had any idea that those types of animals were wandering around here more than a million years ago.”
San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare.
Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils.
The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment.
“We have a confused view of what this time period was like, ” says another scientist. “A discovery like this could really be an important contribution.”
About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California.

Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．Why did the scientists carry on the new research?
| A．To find out if laughter was good to health． |
| B．To discover the best medicine to cure diabetes． |
| C．Because the number of diabetic patients is the largest in the world． |
| D．Because diabetic patients need more laughter than other patients． |
After 12 months into the study, ___________．
| A．C-reactive proteins increase 66 percent in Group C |
| B．the level of the hormones epinephrine stays the same in both groups |
| C．the level of the hormones epinephrine has dropped |
| D．C-reactive proteins reduced 66 percent in Group L |
The underlined part “HDL cholesterol” in Paragraph 3 must be _______．
| A．something bad to our health | B．something good to our health |
| C．a kind of wonderful medicine | D．a kind of dangerous disease |
In what way does laughter benefit people’s health?
| A．Blood is made thick by laughter． |
| B．Laughter makes blood vessels thin． |
| C．Laughter increases blood pressure． |

The writer Margaret Mitchell is best known for writing Gone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life.
Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer’s life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for the Atlanta Journal newspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men tower over her, but she seems very happy and sure of herself. The tour guide explains: “Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as ‘Would you really marry a woman who works?’ And today it’d be ‘Would you marry one who doesn’t?’ ”
The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it “The Dump ” .
Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide says Gone with the Wind became a huge success.

Celebrity(名人) has become one of the most important representatives of popular culture. Fans used to be crazy about a specific film, but now the public tends to base its consumption(消费) on the interest of celebrity attached to any given product. Besides, fashion magazines have almost abandoned the practice of putting models on the cover because they don’t sell nearly as well as famous faces. As a result, celebrities have realized their unbelievably powerful market potential, moving from advertising for others’ products to developing their own.
Celebrity clothing lines aren’t a completely new phenomenon, but in the past they were typically aimed at the ordinary consumers, and limited to a few TV actresses. Today they’re started by first-class stars whose products enjoy equal fame with some world top brands. The most successful start-ups have been those by celebrities with specific personal style. As celebrities become more and more experienced at the market, they expand their production scale rapidly, covering almost all the products of daily life.
However, for every success story, there’s a related warning tale of a celebrity who overvalued his consumer appeal. No matter how famous the product’s origin is, if it fails to impress consumers with its own qualities it begins to resemble an exercise in self-promotional marketing. And once the initial(最初的) attention dies down, consumer interest might fade, loyalty(忠诚) returning to tried-and-true labels.
Today, celebrities face even more severe embarrassment. The pop-cultural circle might be bigger than ever, but its rate of turnover has speeded up as well. Each misstep threatens to reduce a celebrity’s shelf life, and the same newspaper or magazine that once brought him fame has no problem picking him to pieces when the opportunity appears. Still, the ego’s(自我的) potential for expansion is limitless. Having already achieved great wealth and public recognition, many celebrities see fashion as the next frontier to be conquered. As the saying goes, success and failure always go hand in hand. Their success as designers might last only a short time, but fashion—like celebrity—has always been temporary.Fashion magazines today .
| A．seldom put models on the cover |
| B．no longer put models on the cover |
| C．need not worry about celebrities’ market potential |
| D．judge the market potential of every celebrity correctly |
A change in the consumer market can be found today that .
| A．price rather than brand name is more concerned |
| B．producers prefer models to celebrities for advertisements |
| C．producers prefer TV actresses to film stars for advertisements |
| D．quality rather than the outside of products is more concerned |
The underlined sentence in Paragraph 4 indicates that any wrong step will possibly .
| A．decrease the popularity of a celebrity and the sales of his products |
| B．damage the image of a celebrity in the eyes of the general public |
| C．cut short the artistic career of a celebrity in show business |
| D．influence the price of a celebrity’s products |
The passage is mainly about .
| A．celebrity and personal style | B．celebrity and market potential |
| C．celebrity and fashion design | D．celebrity and clothing industry |
In the computer age, most of us take a broadband（宽带）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.The underlined part “a catch” (in Paragraph 2) probably means “_____”.
| A．a rare challenge | B．a desirable plan | C．an efficient device | D．a hidden problem |

| A．Internet connection has not been popular in most cities. |
| B．Internet service providers care about rural（农村的）customers. |
| C．Computer is popular in developing countries. |

Paragraph 4 mainly tells us that technological advancements _____.
| A．make TV and telephone available everywhere |
| B．bring great change to people’s everyday life |
| C．make it possible for more people to use the Internet |
| D．bring faster Internet connections to users |
What may eventually settle the “last mile” problem?
| A．The broadband connection’s getting faster. |
| B．More and more Internet users. |
| C．more and more Internet connections. |
| D．The rapid progress in cell phone technology. |
Every year in the first week of English class, some students inform me that writing is too hard. They never write, unless homework requires it. They find the writing process painful and difficult.
How awful it is to be able to speak in a language but not to write in it, especially with its rich vocabulary. Being able to speak but not write is like living in an enormous mansion and never leaving one small room. When I meet students who think they can’t write, I know, as a teacher my duty is to show them the rest of the rooms. My task is to build fluency and accuracy while providing the opportunity in any writing activity to enhance（增强）the moral and emotional development of my students.
One great way to do this is by having students write in a journal in class every day.
Writing ability is like strength training. Writing needs to be done just like exercise; just as muscles grow stronger with exercise, writing skills improve quickly with writing practice daily. I often see a rise in student confidence and performance after only a few weeks of journal writing.
Expressing oneself in writing is one of the most important skills I teach to strengthen the whole students. When my students practice journal writing, they are practicing for their future academic, political, and emotional lives. They build skills so that some say they might write a great novel, a piece of sorely needed legislation（法规）, or the perfect love letter. That they write in their journals every day puts them a step closer to fluency, eloquence（雄辩）and command of the language.What is the purpose of the passage?
| A．To encourage students to keep a journal every day. |
| B．To analyze students’ problems in learning languages. |
| C．To stress the importance of writing in language learning. |
| D．To introduce an effective way of improving students’ writing. |
The underlined phrase “an enormous mansion” in Paragraph 2 refers to students’ .
| A．writing opportunity | B．large house |
| C．large vocabulary | D．emotional life |
In the author’s view, what can students benefit from the journal writing?
| A．It is beneficial to students’ future career. |
| B．It can make students more emotional. |
| C．It is helpful to students’ homework. |
| D．It can enlarge students’ vocabulary. |
