I was a shy girl. I didn't even like to answer the telephone for fear I'd have to talk to somebody I didn't know. I enjoyed the loneliness of exploring nature. However, at school I had to spend all day in the company of others. My escape was reading. I spent a lot of time studying and was rewarded with good grades. My only failure was Spanish—I'd get all. As on my written work and tests, but Ds and Fs on the spoken part.

    Eventually I went to college. During my third year of college, I had enough of being shy and determined to change my outlook and behavior. One day while at school, I noticed an advertisement for positions on the local classical music radio station. I had grown up listening to classical music, and I could easily pronounce names such as Tchaikovsky, Albinoni, and Chopin.

    I had absolutely no background in radio, and absolutely no hope of getting the job. The idea of talking to thousands of listeners in “radio land” terrified me. However, I luckily survived the interview. I was given brief descriptions of symphonies（交响乐）and a public service announcement to read, and a list of composers' names to pronounce. It wasn't hard for me. I left the recording session（录音时段）with a sense of relief and a sense of accomplishment. About two weeks later I actually landed the job. It was a challenging job, but I grew to enjoy it greatly. I began to feel comfortable talking to people.

    Although I now spend many hours each week talking with people, I'm still basically a quiet person. Perhaps it is my soft voice and my quiet nature that helps draw people out as they respond to my questions as I interview them. My former shyness is a fortune, as I can relate to people who feel discomfortable when they talk to newspaper reporters. I still enjoy moments of loneliness and the peace found in nature. But I'm also glad I decided to make a change in my life that has opened many doors and opportunities that I never knew existed.

    Government in Tibet have denied the permanent( 永久的) closure of Mount Qomolangma National Nature Reserve.

    The announcement came after a report went viral online claiming the base camp of the world's highest mountain was "permanently closed due to heavy pollution" and caused a universal misunderstanding.

    Mount Qomolangma National Nature Reserve was set up in 1988. Covering an area of more than 33, 800 square km, it is home to one of the world's most weak ecosystems(生态系统).

    Kelsang, deputy director of the reserves administration, said ordinary tourists are allowed to visit areas around Rongpo Monastery, almost 5,000 meters above sea level. As for travelers who have a climbing permit, they can go to the base camp at an altitude of 5,200 meters. The mountaineering activities have been permitted by the regional forestry department.

    To conserve the environment surrounding Mount Qomolangma, China carried out three major clean-ups at an altitude of 5, 200 meters and above last spring, collecting eight tonnes of household wastes, human wastes and mountaineering trash. This year, the clean-up will continue, and the remains of mountaineering victims(受害者) above 8,000 meters will be centrally dealt  with for the first  time. Meanwhile, the number of people who stay at the base camp will be kept under 300.

Recently, there are 85 wildlife protectors in the reserve, and 1,000 herders have part-time jobs going around and cleaning up garbage.

These measures aim to strike a balance between various demands such as environmental protection, local poverty relief, mountaineering and education, said Wang Shen, county chief of Dingri at the mountain foot.

    Jarrett Little was road testing his mountain bike outside of Columbus, Georgia, when his riding partner, Chris Dixon, stopped suddenly. Something in the distance moving among the trees had caught her attention. It turned out to be a sandy-colored five-month-old puppy.

    "He was really thin, ribs showing, and a broken leg," Little told John Parks, a reporter from CBS News. The cyclists fed the friendly pup and shared their water. They also quickly realized that the dog was coming with them, although they had no idea how. They were more than seven miles from downtown and riding bikes. "We couldn't leave him," Little said. "Out there next to the Oxbow Meadows, he was going to become the lunch of an alligator living in the river."

    Suddenly, Little had an idea. He carefully picked up his new friend and slipped the 38-pound dog's hind legs (后肢) into the back pockets of his cycling jacket. Then he hung the dog's front paws over his shoulders.

    "He was injured, so he wasn't trying to fight," Little says. "He was also happy that we were there, touching him, and hadn't taken off on him."

    The group's 30-minute ride into town ended at a bike store, where they got more water and food for the dog. That was when Andrea Shaw, an accountant from Maine in town on business, happened by. The dog made a headed straight for her, licking and "loving on her," says Dixon. Shaw was struck and, after learning what had happened, declared her intentions: "I am keeping this dog."

    Shaw called him Columbo and scheduled an operation on his leg. Today, Columbo is living the high life on a farm with a horse, a pony, a six-year-old boy, to keep him company. As Dixon told John Parks, "He is literally the luckiest dog alive."

    Fourth-grader Alice Tapper was on a school field trip when she noticed that most of the girls quietly stayed at the back of the group, while the boys gathered at the front and raised their hands to answer questions. The 11-year-old then realized how often she and her female classmates didn't speak up in class for fears of getting an answer wrong and being embarrassed.

    She decided to change this and launched a campaign to encourage girls to have faith in themselves, even take risks and be leaders —— and support other girls in doing the same. With assistance from her Girl Scout troop (女童子军), she created a new Raise Your Hand program, and soon girls around the country were taking a pledge(承诺) to raise their hands in class.

    In my work as an administration coach I see many women (and some men) with habits that are holding them back. Women at work tend to hang back in meetings for fear they may not have the right answer. They will spend countless hours (and sometimes days) replaying the tapes in their head, while males in similar situations simply move on, until they are perfect when instead they should be establishing relationships. The truth is that after a year no one remembers your nice report. Forget perfect. It doesn't exist. Say what's on your mind and let things go.

    Similarly, women tend to talk more softly than men, which can be problematic, especially the higher up in the organization you go. To have an influence on business, it's not enough to have a seat at the table. You have to have a voice and people have to hear from you. Don't wait for an invitation. Raise your hand, say what you have to say, and when you see an opportunity, go for it!

Vitamin D was recognized a century ago as the cure for rickets, a childhood disease that causes weak bones. Then, in the early 2000s, a pile of studies suggested that low vitamin D levels could be a factor in cancer, cardiovascular（心血管） disease, Parkinson's disease and so on. This simple vitamin seemed to be a cure for whatever troubled us. However, all these observational studies have a fundamental weakness: they can identify a co-occurrence between vitamin D and a disease, but they can't prove there is a cause-and-effect relation.

To look at whether taking vitamin D had curative effects, Manson and her team started the world's largest and most far-reaching randomized vitamin D trial. The study followed nearly 26,000 healthy adults, randomized to receive either 2,000 international units （IU） of vitamin D or a placebo（安慰剂）, for an average of 5.3 years. The volunteers were almost evenly split between men and women, and 20 percent of the participants were black.

The results came as a shock. Not only did vitamin D not reduce rates of cancer or heart disease, but the trial also found that vitamin D did not prevent or improve cognitive function, or reduce the risk of bone fractures（骨折）. The finding about fractures "was a real surprise to many people," Manson says.

In 2011, the Institute of Medicine established an expert committee to conduct a thorough analysis of all existing studies on vitamin D and health. The committee concluded that the bone-strengthening benefits of vitamin D remain steady when blood levels reach 12 to 16 nanograms per millililter. They also found that there were no benefits to having levels above 20ng/ml. According to measurements of vitamin D levels in the general U. S. population, most had levels of 20 ng/ml or more in 2011. Levels have actually risen since then, meaning that most people don't need to take extra vitamin D.

The ups and downs of vitamin D offer a lesson in humility. The relation between the vitamin and disease is far more complicated than it first seemed and a reminder that scientific understanding is always developing over time.
