Joseph Francis Charles Rock (1884–1962) was an Austrian-American explorer, botanist, and anthropologist(人类学家). For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949.

    In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China's southwestern provinces—the Wild West of their day. But gold and silver weren't his task: Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum(阿诺德植物园).

    Botany, though, was just one of Rock's strengths. As an ethnologist(民族学者), he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China's “Cho-Ni” territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II.

    Scientist, linguist, cartographer, photographer, writer—Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord's place “as if he owned the place,” said Lisa Pearson, the Arboretum's head librarian.

    In declaring his successful return under the headline “Seeking Strange Flowers, in the Far Reaches of the World,” the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. “In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance.”

    The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune—about $900,000 in today's dollars. Fortunately, many of his specimens, many of his amazing photos, and his great stories remain.

    A new concept vehicle, Pod was introduced by Toyota and Sony at the Tokyo motor show. The car is intended as a four-wheeled friend. It aims to provide affection, sympathy and encouragement. Like a dog welcoming its master, the car sits up, wags its tail and acknowledges its owner's presence using hydraulics(液压装置) and a multi-coloured LED display panel(引擎) across the front.

    While on the road, the car constantly monitors the driver's mood with pulse and sweat(汗) sensors on the joystick(操纵杆). Cameras focused on the eyes keep watch for any sigh of drowsiness. If a driver appears to be losing his or her cool, Pod will display warnings, play soft music and blow cold air at the face. Drivers are shaken awake with loud music and a shaking chair.

    To improve driving skills, Pod uses a comparison to score drivers, offer advice and rank all Pod owners. Toyota claims that the car will eventually be able to learn its owner's likes and dislikes by monitoring passenger conversations. If the car hears a favorite song being discussed, it will download the track from the Internet and play it without being asked. It will also recommend(推荐) restaurants that might suit the driver's taste and take photographs of passengers when they sound particularly happy.

    In keeping with the moodiness that is the car's main selling point, Pod expresses a form of road anger. If a driver brakes or swerves(急转弯) suddenly, the LED panel shows an angry red and the tail rises at the back.

    Anger is one of the car's ten “emotional states”. Another is sadness — a blue front with tear-shaped lights seemingly dropping from headlights — which appears after a flat tire or when gas is low.

    “We wanted to show that the cars can be cheerful and entertaining,” said Yasunori Sakamoto, part of the Toyota design team. Mr Sakamoto said Toyota has no plans to put Pod on the market. Sad, really.

    The American newspaper has been around for about three hundred years. In 1721, the printer James Franklin, Benjamin's older brother, started the New England Courant, and that was what we might recognize today as a real newspaper. He filled his paper with stories of adventure, articles on art, on famous people, and on all sorts of political subjects.

    Three centuries after the appearance of Franklin's Courant, few believe that newspapers in their present printed form will remain alive for long, Newspaper companies are losing advertisers, readers, market value, and in some cases, their sense of purpose at a speed that would not have been imaginable just several years ago. The chief editor of the Times said recently, “At places where they gather, editors ask one another, 'How are you?', as if they have just come out of the hospital or a lost law case.” An article about the newspaper appealed on the website of the Guardian, under the headline “NOT DEAD YET.”

    Perhaps not, but the rise of the Internet, which has made the daily newspaper look slow and out of step with the world, has brought about a real sense of death, Some American newspapers have lost 42% of their market value in the past three years. The New York Times Company has seen its stock（股票）drop by 54% since the end of 2004, with much of the loss coming in the past year. A manager at Deutsche Bank suggested that stock - holders sell off their Times stock. The Washington Post Company has prevented the trouble only by changing part of its business to education; its testing and test — preparation service now brings in at least half the company's income,

    You may hear about some people who have walked on the moon. Of the outstanding astronauts listed below, who do you think was the most influential in human's history?

Pete Conrad (Apollo 12)

    Because of his dyslexia（阅读障碍）, Pete always failed in his study and had to leave school. Then his father sent him to Darrow School, where he performed so well that he won a Naval Reserve Officers Training Corps (NROTC) scholarship. He took the NASA's test, but his dyslexia ruined the opportunity.

    It was because of Alan Shepard's persuasion that Pete decided to apply again for NASA. He was chosen as the commander of Apollo 12. He landed on the moon on Nov 19, 1969 and spent 31 hours there.

Neil Armstrong (Apollo 11)

    Armstrong's biggest moment came in 1969, when he was chosen for NASA's first manned lunar mission (登月任务), along with Edwin Aldrin and Michael Collins. On July 21, 1969, he set foot on the surface of the moon. which made him the first human to do so. He stayed on the moon for 21 hours. After returning, Armstrong became an international star and was honored worldwide.

John Young (Apollo 16)

    Young was made the commander of Apollo 16, which landed on the moon on April 16, 1972. He spent two days and 23 hours on the moon. Young retired from NASA after serving for around 42 years, which made him the man ever to work for NASA for the longest time.

Edgar Mitchell(Apollo 14)

    Edgar was selected by NASA in 1966, and was later made the lunar pilot of Apollo 14. He followed his commander Alan Shepard onto the moon, staying there for 1 day and 9 hours. Edgar has expressed his firm belief that UFOS belong to other planets. He also firmly believes that American government is in possession of some “recovered alien bodies.”

The Alexander technique

    Until earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.

    The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.

    The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.

    So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.

    So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.

    Plants are boring. They just sit there photosynthesizing (光合作用) while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution (协同进化) started with ants feeding on plants and plants evolving ant-friendly features.

    Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mаmmаlѕ. Тhеѕе іnсludе hollow thorns that аntѕ will live іnѕіdе, or ехtra nесtаr (琼浆) оn lеаvеѕ or stems for the ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed—often in a nutrient-rich area where it'll grow better, and since it's farther away from its parent, they won't have to compete for resources.

    But scientists weren't sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.

    The history of ants and plants evolving together goes back to the time of the dinosaurs, and it's not easy to tell from fossils who fired the first shot. However, it is a question of little significance. Scientists say their study maters because it provides a look at how these widespread and complex interactions evolved.
