    The Gold Coast family holidays are always great fun whether you are from Australia or from abroad. There are beautiful beaches, adventure (冒险) parks, nature parks and so much more.

    There are so many sights to see here. It is a pity to drive in a car and you'll miss a great part of it. Australia is home to many animals and birds that can only be seen when moving slowly and going into the areas where they live.

    When you are on a bicycle, you have the advantage of being able to stop whenever you want to see an interesting animal or bird that you have never seen before. It is a quieter way of transportation as well, so you might even be able to take a picture. When you are on the beach, you can breathe that clean air and view the beauty of the water and sand. It is a totally different experience from passing it in a car.

    There are many choices of hiring (租用) a bicycle to experience the Gold Coast. There are stores that will fit a bike perfectly to your size. These bikes for both adults and children are in many kinds and colors to please any taste. If you have ever wanted to try a tandem bike (双人单车), now is your chance, because they have those too.

    A bicycle hire on Gold Coast is something that everyone should try at least once. This is a wonderful chance for anyone who likes to cycle and it is also a cheap way to travel with your family.

    A new report says living in a city makes it harder for people to concentrate(集中) on some tasks. The research found that people who live in rural areas can focus better than people in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr. Karina Linnell and her team made great contributions. They studied how two groups of people did the same "thinking tasks". The team went to a remote(偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. Dr. Linnell said the tribe who lived in the desert did much better on the tests than those in the town. It's really interesting and shocking.

    Dr. Linnell said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. Linnell said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, "What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better. "The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr. Linnell's research is true, this century might see many of those people return to the great outdoors. Let's wait to see what will happen.

    Melinda Skaar wasn't expecting any phone calls. Skaar was working late in her office at the First Internet bank of California. By 10:45 that night she was almost ready to go home when the phone rang. Picking it up, she heard a guard shouting, "There is a fire! Get out of there." Skaar didn't panic. She figured that it was just a small fire. Her office building was huge. There were 62 floors and her desk was on the 37th floor. Skaar called out to office mate Stephen Oksas, who also stayed late to work. But when they got out to the hallway, they were met by a cloud of black smoke. Rushing back, Skaar shut the door and filled the space at the bottom of the door with her jacket to keep the smoke out.

    Then they called 911. Before they could call their families, however, the line went dead. That meant that they were completely cut off from the outside world. All they could do was wait and hope someone would come to rescue them.

    Minutes ticked by. Smoke began to float into the office. Soon it became hard for them to breathe. Looking around, Skaar noticed a small workroom. It seemed to have cleaner air. So they crowded there. That helped for a while, but in time even the workroom was filled with deadly smoke. Hopeless, they tried to break the windows, but the glass was not breakable. Everything they threw at it just bounced back. Defeated, they struggled back to the workroom. They felt weak and dizzy. Soon Skaar found Oksas had passed out.

    As Skaar and Oksas lay near death, rescuers were rushing to find them. At last, at about 4 a.m., firefighters found them.

    Skaar and Oksas knew they were lucky to be alive. Sunday is my birthday, Skaar told a reporter. She would be turning 29, but she knew she had already got the best present possible—the gift of life.

    Nations in the UN have agreed that the world needs to completely stop plastic waste from entering the oceans. The UN resolution(决议) has no timetable. But ministers at an environment summit believe it will set the course for much tougher policies and send a clear signal to business.

    Under the resolution, governments would establish an international task force(特遣小组) to advise on fighting what the UN's oceans chief has described as a world crisis. One controversial issue is the wish to include businesses on the global task force. Ministers say the problem will not be solved without business, but green groups point out that some firms in the plastics industry have been against restrictions for decades. Vidar Helgesen, a leading voice in the talks, told BBC News, “Business is listening to markets and seeing how marine litter(海洋垃圾) is a growing popular concern. It's possibly the fastest－growing environmental problem and it's therefore a fast－growing problem for business. We need to bring on board those companies that want to change things, and then look at taxes and regulations to make more companies act.”

    Certainly, there has been resistance from plastics firms to the bans. One UN delegate, who did not want to be named, stated that journalists in some countries were being paid by the plastics industry to write stories about job losses following the plastic bag ban. But they did not mention the jobs being created in alternatives, such as labour－intensive basketwork, which provides work for the rural poor. But some governments are standing firm, and the meeting has witnessed individual nations declaring tougher action against single－use plastic bags.

    The UN's spokesman Sam Barratt told BBC News, “Of course we would have liked to have gone further, but this meeting's made real progress. There's now a sense of urgency and energy behind the issue that we haven't quite seen before. What is obvious, though, is that the UN can't solve this problem on its own. We need to do it in partnership with governments, businesses and even individuals.”

    Demand for the Chinese tech company's devices(设备) is red hot even though the country's overall market for smartphones is getting smaller Huawei's China sales rocketed more than 20% in the final quarter of 2018, and experts say that's partly due to the US government's global campaign against the company.

    “The latest tension between the US and China raised the patriotism(爱国主义) in Chinese consumers, said Jusy Hong, an analyst at research firm IHS Markit.

    He pointed out that some Chinese companies encouraged employees to buy Huawei phones late last year. The moves were a gesture of support after the firm's chief financial officer was arrested in Canada in early December at the request of the United States.

    Huawei's booming sales show how major parts of its business continue to increase even as the United States tries to persuade other countries to shut Huawei products out of 5G wireless networks and pursues(追究) criminal charges against it. The company expects to overtake Samsung as the world's biggest smartphone maker by next year.

    Huawei sold 30 million phones in China in the last three months of 2018, nearly three times as many as Apple(AAPL), according to data published this week by research firms Canalys and IDC. Apple's sales plunged almost 20%.

    Huawei's success in China, the world's largest smartphone market, is more than about geopolitics(地缘政治). Chinese consumers love its flagship, high -end- phones because they have great cameras, cutting edge technology and cost less than the latest iPhones, according to analysts. And by offering a selection of cheaper phones, Huawei is able to target a bigger market.

    It also benefited from the troubles this year at ZTE (ZTCOF), a rival Chinese smartphone and telecommunications equipment maker. ZTE was banned by the US government from buying vital American parts for months last year.
