The Golden Gate Bridge in San Francisco，California is one of the world's most beautiful bridges. It is also one of the most visited places in the world. More than 1800 hundred million vehicles have used the bridge since it opened more than 70 years ago.

    The bridge was painted “International Orange” because that color went well with the natural surroundings. The color also is easier to see in the heavy fog that often covers the area. But the Golden Gate Bridge was not named for its orange color. It was named for the body of water that it crosses, the Golden Gate Strait, which is the entrance to the San Francisco Bay from the Pacific Ocean

    Planning for the bridge began in the 1920s when the area around San Francisco was growing. People living in the area needed another way to get to the city besides small ferries. Joseph Strauss was the chief engineer for the project. Work began in 1934.Mr.Strauss demanded the strongest safety protections in the history of bridge building. These included the first use of “hard hats” to protect the workers' heads and special glasses to protect their eyes. A special safety net was suspended under the bridge. This net saved the lives of 19 men during the construction.

    The Golden Gate Bridge opened in 1937.It extends 1280 meters across the water. The total length is 2737 meters. It was the largest suspension bridge(吊桥)in the world until 1964.That is when the Verrazano Narrows Bridge opened in New York City. Today, the Golden Gate Bridge is the ninth longest suspension bridge in the world.

    After retirement, Michael Kennedy could have chosen to take walks around his seaside home. Instead, the former mechanical engineer engaged himself in the toughest task of his life - keeping the thundering waves of the Norfolk coast.

    The 73-year-old has spent the past 14 years building his own sea wall at Hunstanton, piling up rocks picked from the sandy beach to slow the erosion （侵蚀）of the soft limestone （石灰岩）and chalk cliffs. It's estimated that Michael has shifted 200 tons of stone in the last 14 years.

    “It's a real labour of love because I come down here whatever the weather, in spring, summer, autumn and winter,” said the divorced father of two. “It keeps me fit and I love it.”

    Mr Kennedy moved to the area after retiring from the London Underground. Nicknamed Fred Flintstone by locals, he tries to move at least 40 pounds of rocks in two-hour sessions which he finishes by 2 pm.

    Everything he collects is placed into piles at the foot of the cliffs. Larger rocks go at the bottom to provide the main line of defence and smaller ones are placed at the top. He also picks up rubbish and prides himself on having created a spotless, stone-free sandy beach for holidaymakers to enjoy.

    The work goes on six days a week. Saturdays are his day off so that the Chelsea “fanatic” can watch football and other sports. However, there are signs that he is becoming a victim of his own success, as the number of stones has dwindled significantly in recent months.

    “It's confusing, Mr Kennedy said. “Usually every year the stones just come in with the sea but this year we haven't had any.” He added, “I hope to still be doing it when I'm 100 but perhaps just four days a week instead of six.”

    Town mayor Peter Mallam said Mr Kennedy had become “quite a local legend”. “It's fascinating. Everyone knows of the old guy who collects the stones. He's done a sterling effort.”

    It's common knowledge that there are many benefits to being fit, but one large new study found that skipping out on the gym is practically the worst thing you can do for your health. In fact, the study claims not exercising might be more harmful to your health than smoking.

    New findings, published Friday in the journal JAMA Network Open, detail how researchers at the Cleveland Clinic studied 122,007 patients from 1991 to 2014, putting them under treadmill (跑步机) testing and later recording death rates. Researchers found a clear connection between a longer, healthier life and high levels of exercise. The report calls for health care professionals to encourage patients to achieve and continue a strong and healthy fitness routine.

    Although it is widely understood that an active lifestyle can lead to a healthy life, the study concludes that a lifestyle which involves much sitting but little activity is equal to having a major disease and the simplest cure is exercise.

    Dr Wael Jaber, co-author of the study, called the results totally surprising. “Being unfit on a treadmill or in an exercise stress test has a worse prognosis (病情预断), as far as death, than being a smoker or suffering from high blood pressure,” Jaber told CNN. “We've never seen something as noticeable as this and as objective as this.”

    The study also took a look at the risk of being overactive and found that extreme exercisers do not face higher risk of death: the research found that the more a person exercises the lower their death rates.

    The UNESCO has recognized the Chinese art of paper cutting on its Intangible Cultural Heritage List. But paper cutting is at the risk of disappearing.

    Voyo Woo, a Chinese immigrant, who loves paper cutting, worked hard to celebrate the ancient art form. With a keen interest in paper cutting, Ms Woo held a paper cutting exhibition at a shopping center near Washington. "I really love it. I get so much fun by doing it. So I'm just kind of hoping that more people will learn about this art which is about to disappear. I think it's time to take action. So I held it."

    Voyo Woo began to study paper cutting when she was a 14-year-old girl in southeastern China. Voyo Woo's teacher gave her extra training after class because Voyo Woo discovered a special love for it. Later, her beautiful paper cuttings won second prize in a national painting competition. "Paper is the easiest material that you can find. You can just turn it into beautiful art. I think it is like magic to me."

    Ms Woo came to the US after she finished college in 2008. She has been invited to show the art at a wide collection of events. She also has shown her skill and works at famous museums like the Smithsonian Institution's Freer and Sackler art galleries in Washington.

    "I saw so many people coming to me and asking me. They were amazed. I think it's important to introduce the art form to American people or anyone who is interested."

    Ms Woo placed examples of her art around her as she displayed paper cutting at the shopping center. Ann Russ, a shopper, was attracted by the nature of the work. She said it put her at ease. "I like to know about Chinese art, specifically because it's almost relaxing to put that much effort into it," Russ said.

    Want to explore new cultures, meet new people and do something worthwhile at the same time? You can do all the three with Global Development Association(GDA). Whatever stage of life you're at, wherever you go and whatever project you do in GDA, you'll create positive changes in a poor and remote community(社区).

    We work with volunteers of all ages and backgrounds. Most of our volunteers are aged 17-24. Now we need volunteer managers aged 25-75. They are extremely important in the safe and effective running of our programmes. We have such roles as project managers, mountain leaders, and communication officers.

    Depending on which role you choose, you could help to increase a community's access to safe drinking water, or help to protect valuable local cultures. You might also design an adventure challenge to train young volunteers.

    Not only will you help our young volunteers to develop personally, you'll also learn new skills and increase your cultural awareness. You may have chances to meet new people who'll become your lifelong friends.

    This summer we have both 4-week and 7-week programmes:

    GDA ensures that volunteers work with community members and local project partners where our help is needed. All our projects aim to promote the development of poor and remote communities.

    There is no other chance like a GDA programme. Join us as a volunteer manager to develop your own skills while bringing benefits to the communities.

We've all heard the advice to "get out of your comfort zone" by taking on a new challenge. A recent study goes a step further: Make discomfort a direct goal. That's more likely to motivate you {#blank#}1{#/blank#} if you only focus on what you hope to learn.

In the first of five experiments, the researchers assigned several hundred students training at Second City Chicago {#blank#}2{#/blank#}（participate） in a small-group improvisation（即兴） exercise, and then instructed half of the group that their goal during the session was "to feel awkward and uncomfortable." The rest, {#blank#}3{#/blank#}（that） in the control group, {#blank#}4{#/blank#}（tell） to "feel yourself developing new skills." Members of the first group kept at the exercise longer than the others did and took {#blank#}5{#/blank#}（great） risks.

Experiments {#blank#}6{#/blank#}（involve） other dimensions of personal growth—engaging in expressive writing, learning about gun violence, and hearing about opposing political {#blank#}7{#/blank#}（belief）—produced similar results.

Reframing anxiety as excitement has been proven a way to improve singing in front of strangers, and thinking of stress as {#blank#}8{#/blank#} means to boost achievement demonstrated a stress-management technique.

"When people reinterpret negative experiences as {#blank#}9{#/blank#}（function）, they are more willing to engage in tasks that call forth those experiences," the researchers explain. "Instead of seeing discomfort as unrelated to the goal {#blank#}10{#/blank#} a signal to stop, they will start perceiving it as a sign of progress toward their goal."
