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.

    In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mum was making spread like wildfire throughout the neighborhood. My mum was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.

    My mum went into her business because she had a creative idea. She got orders and filled orders. But there was no purpose and no real strategy(策略). In 1991, my mum' s partner got into financial trouble and there was not enough money to support either my mum or her partner.

    So if you are led by your creativity or enthusiasm, make sure you ask yourself what you want out of your business. If you don't set goals, how will you know what direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can't keep scores if you don' t know what game you are playing.

    After my mom's partner gave up, she had to abandon(抛弃) her business to support herself. She swore（发誓）she would run a business again and do it differently the next time. However, there wasn't a "next time" for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was. She never had an opportunity to be everything that she could be.

    There are no right or wrong goals, only the ones that matter to you. Set them so that you can make progress and achieve success, whatever that may mean to you.

    The 90-minute documentary, Amazing China, which is co-produced by China Central Television and China Film Corp, opened in theaters nationwide on Friday.

    The film focuses on the major achievements the country has made since the 18th National Congress of the Communist Party of China in 2012 under Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era（时代）.

    The documentary focuses on key Chinese infrastructure（基础设施）projects in aerospace, high-speed rail, the Hong Kong-Zhuhai-Macao Bridge and the world's largest single-dish telescope FAST.

    The documentary also informs viewers that seven of the world's 10 biggest sea ports are now in China. And that the country now has the longest high-speed rail network in the world.

    Speaking of the significance of the new documentary for the Chinese, La Peikang, the head of China Film Corp, says: “It's not only about showing the achievements, but presenting the status quo of China.

    “The film will help people to know our country better. The moving stories behind the Chinese miracles reflect the people's endeavors and spirit.”

A good documentary is usually a vivid portrayal（描绘）of individual stories rather than slogans, and Amazing China is no exception.

    One of the most touching moments in the film is probably footage from an interview of Nan Rendong, often called the “father of FAST”.

    Amazing China also focuses on common people.

    In the film, you see a young Tibetan woman volunteering in rural areas to help people poverty.

    The movie shows that their work is not easy, but their spirit and unwavering belief make it possible to achieve their targets. And, they are just representative of the many Chinese who work as hard.

    China is the world's second-largest economy. But the country still faces “the contradiction between unbalanced and inadequate development and the people's ever-growing needs for a better life”, as stated in the CPC's 19th National Congress in November. However, as this cinematic production proves, the documentary is a good way for country to boost self-confidence and to aspire for a brighter future.

    Bats are the only mammals(哺乳动物) that can fly a great distance, but they have another ability. Many bats live a very long time for an animal of their size. European researchers are studying bats to understand why they lives0 long. They hope to make discoveries aimed at fighting the aging process in human beings.

    Last week, the group of scientists said they had identified important biological qualities in some bat species. The group studied bat chromosomes(染色体), a line of genes found in the nucleus(细胞核) of cells. The scientists were most interested in structures connected to the ends of the chromosomes. They are called telomeres(端粒), which protect the ends of chromosomes and shorten each time a cell divides. Scientists believe this shortening process causes cells to breakdown. They say this is what causes aging.

    The European researchers studied 493 bats from four bat species. The group used information that had been gathered over more than 60 years. Of these animals ，the greater mouse-eared bat generally lived the longest, an average of 37 years. The scientists said this and a related species, which are grouped together under the name Myotis, had telomeres that did not shorten with age. Another Myotis bat holds the record for oldest age, reaching 41years. The scientists' findings suggest that these bats cells have the ability to maintain and repair their telomeres. This, they said, helps guard against the aging process.

    Based on its body size, a bat like the greater mouse-eared bat would be expected to live four years. But, these mammals have been found to live nearly 10 times longer than that. The scientists found that only 19 species of mammals live longer than humans when their body size is considered. Eighteen of these are bats.

As I drove along the road, a small car flew across the center divider from the opposite direction and crashed into my car head-on, I fainted and was awakened by the ringing of my mobile phone.

I was brought to Kuala Lumpur General Hospital bleeding on from my nose, mouth and legs. But the hospital staff was too busy to attend to me, so I called a friend to tell him about the accident. Some friends arrived very soon and sent me to a private hospital nearby. I saw my injured feet hanging from my body, blue and lifeless, and I begged the doctors to save them at all costs. They calmly promised to do their best.

The doctors made it. After I was discharged, I was given ten months medical leave. My heart sank, knowing that it meant I, a big man, couldn't work. How was I going to support my 65-year-old mother and other family members? I felt completely helpless, but a lot of unexpected blessings came my way. I had many visitors during my 14 days in hospital and when I was recovering at home. Friends and relatives helped me with my banking, insurance or simply came to cheer me up.

When the casts (石膏) were removed, I did not let the sight of my weak legs discourage me. I worked hard at my physiotherapy (物理疗法) with only one aim. After eight months, I was walking without the aid of a walking stick. On February the following year, I returned to my job again. Today, after eight years, I have travelled to many countries as a tour leader.

The accident makes me realize how lives can change in a split second. I value life more, not only of my own but also of everyone I know, and I will always try to help when I know of someone in trouble.

Fifteen-year-old Sansa has been writing for eight years and has been working on a book for the past four. Feeling stuck and unable to write, she started searching for writing groups in Los Angeles, looking for guidance. When she found WriteGirl, she was inspired.

Keren Taylor started WriteGirl in 2001 as a way to help teen girls who did not have access to creative writing programs. "Teen girls are incredibly vulnerable(脆弱的) and invisible," Taylor said. "They really need to be lifted up and inspired."

At WriteGirl, 400 women writers volunteer to mentor(指导) 700 teenagers a year. Every girl who has gone through the mentorship program has gone to college and several have pursued careers as professional writers. Through the program, girls dive into poetry, fiction, songwriting, play and so on, learning techniques from professional women writers. This leads to well-rounded training and sets WriteGirl apart from other organizations.

A typical exercise at WriteGirl is mic and rant, a 30-second session before writing for each girl. As a vehicle for teens to get their ideas out, it empowers girls to explore anything meaningful to them. "Not the flowery language, or rather, complicated expressions that sound skillful, but more of the natural, this is what I'm thinking and what I'm feeling." Taylor said.

Sansa's mentor Danyella Wilder is attracted by the long-term nature of mentoring at WriteGirl. Wilder wishes she had a program like this herself when she was 15. "To just have an organization where people are spending their time just to tell you, ‘Hey, good job,' or ‘That was amazing.' You're at the age where you need to hear that."
