Six million people visit Grand Canyon in the US every year. For the purpose of helping project Grand Canyon for your fellow visitors and future generations, please follow the guidelines below.

    Camping

    To protect the park, camping is allowed only within permitted campgrounds. Permits are required for overnight camping at the North Rim. Advance booking can be received by mail. Please write: Information Center, P.O. Box 129, Grand Canyon, AZ 86023.

    Fires

    Because of the extreme fire danger, campfires are not allowed except at Mather and Desert View campgrounds. Collection of firewood is not allowed either.

    Hiking（远足）

    Please stay on permitted paths. Otherwise you may destroy desert plants. Pack out what you pack in, so you leave no signs of your visit. It is important to keep in mind that you are in a national park where wildlife exists.

    Weather

    The weather at Grand Canyon can change very quickly. With so much rock, lightning(闪电) causes a particular danger during sudden summer storms These storms also frequently bring floods inside valleys, a danger to hikers. Watch the skies and check daily weather reports.

    Wildlife

    Do not feed park wildlife. There have been a few cases at Grand Canyon National Park where deer(鹿) were purposely shot because there are plastic bags that left them sick and weak. Hungry deer car be danger and have kicked and bitten visitors at Grand Canyon. Some other animals will also beg and bite. For your own safety and the well-being of the animals, please do not feed wildlife, no matter how gentle they may appear.

    It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited.

    My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But… where was my mobile phone? I had that familiar sinking feeling. Yes, I'd left it at home.

    No mobile phone. I'm sure I'm not alone in feeling anxious, on edge and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience 'nomophobia' (无手机恐惧症), the fear of being out of mobile phone contact.

    That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones.

    It says we check our mobile phones 34 times a day, and that 18-24 year-olds, especially girls, are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.

    Do you have nomophobia?

    You never turn your phone off

    You frequently(频繁地) check for texts, missed calls and emails

    You always take your phone to the bathroom with you

    You never let the battery run out

    It's funny to think that around 20 years ago the only people with mobile phones would be businessmen carrying their large, plastic 'bricks'. Of course, these days, mobile phones are everywhere. A UN study from this year said there would be more mobile phones than people across the world by the end of 2020.

    And when there are more phones than people in the world, maybe it's time to ask who really is in charge(主管)? Are you in control of your phone, or does your phone control you?

    So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all – still always late!" And we had a great afternoon catching up, full of jokes and stories, with no desire(欲望) to check my phone.

    Not having it with me felt strangely free. Maybe I'll leave it at home on purpose next time.

    A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower.

    A biodegradable (生物所能分解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.

    Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and is able to change shape. Over time it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms fertilizers. These feed the seed and help the flower grow.

    Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is throw n away. “We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.

    As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be throw n away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists.

    “The seed comes out and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.

    Mother Teresa was born in Yugoslavia on August 27th, 1910. She attended the government school near her home until she was eighteen. At that time, some doctors and nurses from Yugoslavia were working in India, and they often wrote to school about their work. She decided to join them one day.

    When she finished school, she went first to Britain. Then a year later she went to India, where she began to train to be a teacher. After training, she was sent to Calcutta, where she taught geography at a school and soon after she became headmistress. (女校长)

    However, although she loved teaching, in 1946 Mother Teresa left school and went to work in the poor parts of Calcutta. Later she trained to become a nurse in Panta, and then began her work helping the poor and comforting the dying in the streets of the city. Slowly others came to help her, and her work spread to other parts of India.

    Mother Teresa is now a well-known person. Many photos have been taken of her as she traveled the world to open new schools and hospitals in poor countries. In 1979, she was given the Nobel Peace Prize for the lifetime of love and service she has given to the poor.

    The Ice and Snow Festival Highlights

    It will fall upon January 1st, 2019 and last till the early March, 2019. Based on the theme of “Bright Pearl of the Crown of Ice and Snow”, a variety of activities about ice and snow, concerning tourism, culture, fashion and sport, will be open to all tourists.

    In 1999, 36­year­old Tori Murden McClure became the first woman to row also (单独地) across the Atlantic Ocean, from the Canary Islands to the Caribbean. The journey of just over 5,300 kilometers took the American 81 days. Her boat, The American Pearl, was only 7 meters long.

    McClure is a real adventurer. She has been on many mountaineering expeditions, including climbs in Alaska, Kenya and Antarctica. She was also the youngest person in a team that skied 1, 200 kilometers across Antarctica to the South Pole in 1989, and became one of only two women ever to travel to the Pole by land.

    The journey across the Atlantic was her third attempt. The first time she failed because of illness, and during her second attempt, in 1998, she nearly died. She had rowed nearly 5,000 kilometers when her boat was hit by Hurricane Danielle. McClure was suddenly in the middle of 80 kph wind, and surrounded by waves that were 20 meters high. Her little boat turned over five times. McClure was sure that she was going to die­she took the video recorder that she had brought with her and recorded a farewell message to her family and friends. The hurricane continued into night, and The American Pearl turned over five more times. McClure was determined not to send a signal asking to be rescued­she didn't want other people to risk their lives, too. But after the eleventh turning over of her boat, she finally sent it and a large ship came and found her. However, they couldn't get her boat out of the rough sea­it was found months later near the coast of Portugal.

    Tori McClure had concussion (脑震荡) and a dislocated shoulder when she got home. Many people might have given up after an experience such as this, but one year later, McClure was back in her repaired boat and trying again. This time she was successful­and although she again met a hurricane on the journey, which stopped her from breaking the record for the fastest transatlantic (横渡大西洋的) rowing crossing, she only overturned once!
