    Choosing the right job is probably one of the most important decisions we have to make in life, and it is frequently one of the hardest decisions we have to make. One important question that you might ask yourself is: “How do I get a good job?”

    {#blank#}1{#/blank#}. There are people who can answer an insignificant advertisement in the local paper and land the best job in the world; others write to all sorts of places all over the country, and never seem to get a reply at all. Still others believe that the in person, door-to-door approach is by far the best way to get a job; and then there are those who, through no active decision of their own, just seem to be in the right place at the right time. {#blank#}2{#/blank#}.

    LUKLA, Nepal(Xinhua) – Qomolangma, known as Mount Everest in the West, once negatively recognized as the “world's highest junkyard”, is set to become cleaner as 30,000 porters(搬运工)have been mobilized(动员)for waste collection and disposal from the mountain's southern side. The cleanup drive was launched recently near Lukla airport, one of the world's most dangerous airports yet a vital gateway to the world's highest peak.

    “Our major task is to keep Everest, which is the pride of the world, clean. This campaign aims to transport 100 tons of nonburnable garbage from the Everest region to Kathmandu in 2018,”Ang Dorje Sherpa, chairman of the Sagarmatha Pollution Control Committee said.

    The SPCC, an environmental conversation organization, has made it mandatory(强制性)since 2013 that every climber should carry down 8 kilograms of trash, but for trekkers(旅行者)there is no such regulation. Due to this, more than 100 tons of waste gets collected in the region annually.

    According to Nepalese government statistics, nearly 50,000 domestic and foreign trekkers visit the Qomolangma region annually, while more than 400 mountaineers attempt to scale the peak. The collected waste mostly includes empty beer bottles and cans, oxygen bottles, torn tents and sleeping bags, food bins, and discarded mountaineering and trekking equipment. The trash was collected by local groups in more than a dozen villages while the waste was transported down the mountain in sacks(麻布袋)by porters and yak-hybrid animals as zopkyos. The cleanup covered settlements from up to 5,000 meters near the base camp, to Lukla airport located at an altitude of 2,805 meters.

    On the first day of the campaign, several tons of waste was sent off to Kathmando from Lulka on planes belonging to Tara Airlines, one of the leading private airlines in Nepal. The airlines have set an ambitious target of flying out 100 tons of waste from the region in 2018, as a part of its commitment to the UN Sustainable Development Goals against climate change. The company's CEO Umesh Chandra Rai said: “We hope that this campaign will help the local people to maintain a pristine(原始的), natural and unspoiled environment so that more trekkers will come from everywhere, making the trekking industry here more sustainable.”

    People usually visit cafes to ease themselves of their tiredness and keep themselves from falling asleep, but Mr. Healing, a popular cafe chain in South Korea actually does the opposite. Customers can come in, order a drink, lie down in a comfortable massage chair, and take a nap.

    Many Koreans suffer from a lack of sleep as a result of overworking, so any opportunity to relax and even take a nap is greatly appreciated. Mr. Healing is the perfect place to go when you're on a short work or school break and you need to catch up on sleep. The cafe offers massage periods in various modes, depending on how much time you have and how you choose to spend it.

    The 20-minute session is priced at $3.5, the 30-minute massage costs $7, and the 50-minute session is $9, all of which also include a drink. Once you make your choice, you are taken to the “healing center”. You are asked to take off your shoes as well as any jewelry that might damage the chairs, after which you can choose a massage mode, from “stretch” or “sleep”. You can start with stretch for a few minutes, and then switch to sleep if you want to take a short nap. After it comes to an end, you are taken back to the cafe area to enjoy a coffee or one of the many other refreshing drinks on the menu.

    Mr. Healing cafes are so popular in Korea that customers are advised to make reservations in advance to be sure that a massage chair is available. “I have to sit on a chair and stare at a computer monitor all day due to my job, the healing room was truly effective to relieve tiredness and stress from weekdays,” said Park Hye-sun, a 24-year-old officer.

    Some have described Mr. Healing and other similar relaxation cafes in South Korea as simple fashions, but others see them as a sustainable business model, because they offer a service that Koreans really need.

    In the waters off Brisbane, Australia, a seven­foot­long sand tiger shark swims in pain. A two­foot­long spike sticks out of her side. It's a piece of fishing equipment that the shark ate carelessly. After traveling into her body, the spike punctured(刺) through the shark's stomach.

    A man swimming in the water notices the shark. Then, he warns Sea World Marine Park in the nearby town of Gold Coast. Sea World sends a 12­person team from its rescue center to where the shark was discovered in Moreton Bay Marine Park. Soon, they find her lying on the seafloor. "She'll die without help,"says Trevor Long, leader of the rescue center.

    Using an onboard crane(吊车), the rescuers move the shark into their boat's 13­foot­long tank(缸). Then Dr. David Blyde gives the shark pain medicine and performs an operation to remove the spike. After that, the team sails with the shark to Sea World 33 miles away. They place the fish in a 49­foot­long tank and wait to see if she gets better.

    To give the shark's stomach time to get better, she isn't fed for the first few days. A week after her operation, Long offers the shark a small, dead fish. The animal refuses to eat. But days later when he drops another fish into her tank, the shark enjoys her meal. By now the shark's wounds are getting better.

    Two weeks after her rescue, they take the shark back to the boat and return her to Moreton Bay Marine Park. As the fish is lowered by the crane to the water's surface, two rescuers jump into the ocean and guide her into the sea. From the boat, Long watches her swim away." The shark has another chance," Long says.
