More over smart phone, the intelligent watch is about to take your spot as the latest hi­tech current, allowing wearers to glance at messages and even take calls without touching their phones. The i'm Watch, available since 2011, is the flagship product of an Italian company—i'm. This smart watch is an assist to the smart phone, with which it can communicate by Bluetooth wireless technology. It means you can leave your phone in your pocket as you answer or reject a call, review e­mails or read updates from friends on Twitter or Facebook.

    The i'm Watch also has its own applications, such as i'm Sport, which links with a heart rate detector (检测器) to allow a runner to check his pulse. Such functions already exist in specialized sports watches but not on watches that are linked to smart phones.

    With a square shape, a 3.8­centimeter touch screen and various colors, the i'm Watch sells for a minimum of 300 Euros ($390) for the basic model and prices climb to 16 000 Euros for a luxury model in silver or decorated with diamonds.

    So far, the watch has already found 30 000 buyers, 80 percent of whom are men aged 25 to 50. “Seventy percent are iPhone users, 25 percent Samsung and the rest are other telephones using Google's Android operating system，” said Massimiliano Bertolini, a manager of the company, which aims to sell more than 200 000 watches this year. The company's target market is the person who is always glued to his smart phone, even in meetings or at the movies, or people who wish to keep an eye on their heartbeat during exercise. They will especially target women with advertisements emphasizing its design rather than its technology.

    A popular saying goes, "Sticks and stones may break my bones, but words will never hurt me." However, that's not really true. Words have the power to build us up or knock us down. It doesn't matter if the words come from someone else' or ourselves—the positive and negative effects are just as lasting.

    We all talk to ourselves sometimes. We're usually too shy to admit it, though. In fact, more and more experts believe talking to ourselves out loud is a healthy habit.

    This "self-talk" helps us encourage ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying "Good job!"!

    Often, words come out of our mouths without thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner Or harsh (刻薄的)and critical language will most likely cause the clerk to be defensive.

    Words have power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

    Words have power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem(自尊) and encourage others to do their best Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

    Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.

    “I would never have said to my mom, 'Hey, the new Weezer album is really great. How do you like it?'” says Ballmer. “There was just a complete gap in taste.”

    Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.

    Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.

    No wonder greeting cards today carry the message, “To my mother, my best friend.”

    But family experts warn that the new equality can also result in less respect for parents. “There's still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College. “In the middle of that change, there is a lot of confusion among parents.”

    Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.

    “My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side,” explains Mr. Ballmer. “It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”

    Dr Dian Fossey, one of the world's leading women scientists, had a remarkable career. The work she devoted her life to protecting and studying the mountain gorillas (大猩猩) of Africa—has proved highly effective and has resulted in the steady (平稳的) increase of this most endangered great apes.

    Fossey made her first trip to Africa in 1963. Three years later, she returned to Africa to begin a long term study of the mountain gorillas. She set up camp in the Democratic Republic of Congo but moved to Rwanda because of political reasons in 1967. She established her "Karisoke" Research Centre camp on September 24, 1967.

    Fossey's aims were to study gorilla ecology (生态学) and social organization. She found that in order to achieve this, she needed to recognize individual gorillas, which required that the gorillas get used to her presence (出现). By copying gorillas' behaviour and sounds, Fossey began to gain their trust, and in 1970 an adult male gorilla she had named "Peanuts" reached out to touch her hand.

    Close observations over thousands of hours enabled Fossey to gain the gorillas' trust and bring forth new knowledge about their behaviour. Stories and photographs of her work were published in National Geographic Magazine and elsewhere.

    In 1977, one of Fossey's favorite gorillas, Digit, was killed by poachers and she established the Digit Fund to help raise money for gorilla protection efforts in the same year.

    On December 26, 1985, Fossey was murdered while going back to her house in Karisoke. Her body was discovered near the research centre. Most probably? Dian Fossey had been killed by the poachers she'd fought against. On her tombstone (墓碑): "No one loved gorillas more..."

    In 1988, the life and the work of Fossey were made into a movie based on her book.

Many on the Mountain

We often see people waiting in lines at supermarkets, theatres and amusement parks. Surprisingly, some people even have to wait in line at the summit (顶峰) of Qomolangma in the Himalayas. 

The best time to climb the Himalayas is during the months of April and May, as well as some days in September and October. "In these periods of recent years, the path contains rocks and deep crack from melting ice due to the warm weather, which make expeditions up the mountain more dangerous," said Apa, an experienced Nepalese guide. During this year's climbing season, crowds of climbers became stuck in a long line near the summit. The line is above the mountain's highest campsite—about 8,000 meters above sea level. 

However, most people can only spend a few minutes at the summit without extra oxygen supplies. Twenty-one mountaineers have died in the Himalayan mountains so far this year, according to Gripped, a magazine dedicated to mountain climbing. Eleven of these climbers died on Qomolangma. 

This death count marks a four-year high. Overcrowding, inexperience and poor weather have been the most common causes of death, USA Today reported. 

After these tragedies, one question remains: Why do so many people risk their lives to climb the mountain? The answer differs from climber to climber. Studies suggest that people who take risks tend to perceive themselves differently than people who avoid risky activities. But for adventurers who are drawn to the Himalayas, reaching the summit of Qomolangma is a lifelong dream, according to Discovery News. 

"Qomolangma is like a light to bugs that attracts people once they hear about it. It represents the ultimate for many people," US mountaineer Alan Arnette said. Technological advances have also encouraged more people to climb the mountain. People can get high-tech safety equipment more easily than before. And with the internet, climbers know better than ever about how to reach the summit safely, Yahoo Travel noted.

A grocery store in Ann Arbor, Michigan opened on Tuesday to the public. This is an artist's uneatable creation. The Plastic Bag Store presents shelves filled with items such as meat, eggs, cakes and so on, all of which are made from single-use plastics taken from streets and garbage.

The store at times during the day will be transformed into a stage for a series of short films in which puppetry(木偶戏表演), shadow play, and handmade sets are used to tell a story of how the overabundance of plastic waste we leave behind might be misinterpreted by future generations—and how what we value least may become our most lasting "cultural legacy (遗产)".

Theater and film director Robin Frohardt is the creative driving force behind the Plastic Bag Store. "I got the idea many years ago after watching someone bag and double-bag and triple-bag my groceries," Frohardt said on Tuesday. "I just was sort of struck by how much packaging was involved in our everyday lives. And it just seemed so unreasonable. I just thought, maybe I could set up a project to change it." Combining a real-life supermarket with film experience, Frohardt planned to use art and humor to question our culture of consumption and convenience and to show one of the greatest problems of our planet.

Plastic bags are created by fossil (化石) fuels and often end up as waste in landfills and the ocean. Americans throw away 100 billion plastic grocery bags per year. She hopes that she can continue to tour with the project and bring it to different communities. "My dream would be that this project will become unnecessary one day," said Frohardt.

 "Frohardt's work reminds us, with humor, to think not just about the next two weeks, but also about the next two decades and the next two centuries. What will remain hundreds of years later? We hope that our legacy will be plays rather than piles of plastics," said Tim Tompkins, President of Times Square Alliance.
