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 student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃惊的）ways of cheating every day: some claim that certain accounts of cheating can be justified, but overall it can always be prevented.

    Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.

    There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the student could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students refrain(制止) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.

    It may be difficult to accomplish, hut cheating can be prevented. 1'eachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling（驱逐）a student, which will most likely hinder their plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way 10 avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.

    There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.

    The first Europeans to occupy Canada's Prince Edward Island were the French in the 1500s. At that time, its name was Ile Saint-Jean. When the British took over in 1758, they changed the name to its current one in honor of Prince Edward, the first son of Britain's King George Ⅲ.

    Today many communities find their places in Prince Edward Island, but Charlottetown is the only one that can call itself a metropolitan(大都市)area, despite the fact that it is a small one. About 60,000 people live in the city and surrounding area. The city's center area remains relatively unchanged from its 19th century beginnings. Charlottetown's boardwalk runs alongside the water, past docks, boats, shops and restaurants. Historic homes line the streets. During summer months, costumed characters walk around the city and tell of it history.

    Cavendish beach welcomes beach lovers. The gulf streams makes the water warm and wonderful for swimming, and the island's 1,760-kilometer coastline means a beach is never far away.

    Nine of PEI's 63 lighthouses will welcome visitors in the summer. Besides enjoying stunning views from the tops, visitors can browse in the small museums and learn about the island's history.

The most popular time to visit PE I is July to August, when the average temperature reaches 23℃ during the day. From January to February, the average daytime high is only -3.3℃. Each winter, an average 318.2 centimeters of snow fall on the island, covering it with a white blanket.

    Considering the island's many visitors, it's no surprise that tourism is important there. Other key industries on the island are agriculture, fishing and information technology. With so much to offer, the island is naturally a desirable place to live as well.

    If you frequently travel for business, Stay bridge Suites offer you a range of home comforts. Four recent visitors to Staybridge Suites explain why they booked, what they enjoyed and what made them want to return.

Claire Metcalf

    “The concept is great, but the staff are the ones who really make it. ”she says. “It takes a lot of discipline to always be friendly, but the staff at Staybridge Suites do that. They genuinely care about you.”

Andrew Roberts

    “One of the best things is having my own kitchen. I often end up working late and I don't fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. ”

    “The main thing for me is being able to cook and have my own little flat. The staff are amazing. It is great to be recognized by them, ”he says.

Pauline Robinson

    “What I love about it is the way that you are treated by the staff,” she says. “Some of the staff have been there all that time and they do look after you well. As a woman staying on my own, it is reassuring that they look out for you, and recently when I was poorly they even brought things I needed to my room. ”

Ryan Ruckledge

    “The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I'm able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don't want that.

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: Cinderella.

    Cinderella made more like $ 70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, “Anyone will find something to enjoy in it.” Steven Rea of The Philadelphia Inquirer called the movie “a winning re-do”. Richard Corliss of Time magazine wrote that “Disney finally got Cinderella right. ” Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, “This Cinderella is all dressed up with nowhere very interesting to go.”

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sales. And Disney has widened its usual market for Cinderella products.

    There are products connected to the Disney movie targeted (面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create Cinderella's shoes”. You can buy them for about $ 5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince (王子).

    The make-up (化妆品) company MAC quickly sold all its products connected to Cinderella. HSN is a popular website selling clothing and objects for the home. The marketer is now also selling Cinderella products.

    So, is there anything left for the children, those people we think of as the traditional audience (观众) for the age-old tale? Yes, you can find toys and other children's products at the American store JCPenney. Of course, you can also visit a Disney store.

    People have grown taller over the last century, with South Korean women shooting up by more than 20cm on average, and Iranian men gaining 16.5cm. A global study looked at the average height of 18-year-olds in 200 countries between 1914 and 2014.

    The results show that while Swedes were the tallest people in the world in 1914, Dutch men have risen from 12th place to claim top spot with an average height of 182.5cm. Latvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later, with an average height of 169.8cm.

    James Bentham, a co-author of the research from Imperial College, London, says the global trend is likely to be due to improvements in nutrition and healthcare. "An individual's genetics has a big influence on their height, but once you average over whole populations, genetics plays a less key role," he added.

    A little extra height brings a number of advantages, says Elio Riboli of Imperial College. "Being taller is associated with longer life expectancy," he said. "This is largely due to a lower risk of dying of cardiovascular(心血管的)disease among taller people."

    But while height has increased around the world, the trend in many African countries causes concern, says Riboli. While height increased in Uganda and Niger during the early 20th century, the trend has reversed in recent years, with height decreasing among 18-year-olds.

    "One reason for these decreases in height is the economic situation in the 1980s,"said Alexander Moradi of the University of Sussex. The nutritional and health crises that followed the policy of structural adjustment, he says, led to many children and teenagers failing to reach their full potential(潜力)in terms of height.

    Bentham believes the global trend of increasing height has important implications "How tall we are now is strongly influenced by the environment we grew up in," he said. "If we give children the best possible start in life now, they will be healthier and more productive for decades to come."
