“I could see a huge flow (流动) of water, coming down fast from very high. I had no idea of shape, or situation, or anything. It was just so big.”

    These are the words of the great English writer Charles Dickens. He wrote them when he was visiting Niagara Falls. This waterfall is on the border (边界) of the United States and Canada. It is one of the largest in the world, and the largest in North America.

    Niagara Falls is on the Niagara River. The river divides just before the waterfall, and there are actually three waterfalls. On the American side are American Falls and Bridal Veil Falls. Horseshoe Falls is mostly on the Canadian side. The name comes from its shape — like a horseshoe, in a half circle. Horseshoe Falls is the widest of the three.

    People mainly know about Niagara Falls because of its size and natural beauty. However, the Niagara River is also an important source of electricity.

    In the 1890s, the Westinghouse Electric Company built a large power system (电力系统) on the river. Many other companies also hoped to use the land around Niagara Falls for factories and power systems. However, around the same time, many people began to work to protect the natural area. Soon, the governments of the United States and Canada got involved with it. They protected the land around Niagara Falls. They made parks — green, natural areas. No one could buy this land for factories. For hundreds of years, millions of people have visited Niagara Falls to enjoy its beauty.

    David Cameron is urging today's youngsters to abandon French to concentrate on the tongue of the future—Mandarin(普通话)。

    Cameron said: "I want Britain linked up to the world's fast-growing economies. And that includes our young people learning the languages to seal tomorrow's business deals.”

    "By the time the children born today leave school, China is to be the world's largest economy. So it's time to look beyond the traditional focus on French and German and get many more children learning Mandarin.” To strengthen his message , he quoted Nelson Mandela—the former president of South Africa who said "If you talk to a man in a language he understands that goes to his head; if you talk to him in his own language that goes to his heart.”

    Cameron said that a partnership between the British Council (英国文化协会) and Hanban will double the number of Chinese language assistants in the UK by 2016 and provide increased funding to schools of offering Mandarin as a language choice. In a development of the UK—China School Partnership programme , funding will also be provided for 60 headteachers to make study visits to China in 2014.

    In recent research the British Council found only 1% of the adult population speaks Mandarin to a level that allows them to conduct a basic conversation. Just 3,000 pupils in England, Wales and Northern Ireland entered for Chinese languages GCSEs in 2013, putting it far behind the traditional choices of French with 177,000, Spanish with 91,000 and German with 62,000 entrants(加入者), as well as Urdu, Polish and Arabic.

    Professor Dame Helen Wallace, the British Academy's foreign secretary, said, " a lack of qualified teachers could be a barrier to improve its popularity.”

    Laura Chan, one of the co—founders of a bilingual Mandarin—English primary school, said the prime minister's announcement was good news for the status of Mandarin. She said, "It's a great help. It will increase people's awareness of Mandarin as a language they can learn.”

    Standing in line for the latest iPhone at the Apple store  queuing for tickets to the match or even just waiting at the post office might just have got a lot easier.

Japanese car-maker Nissan announces that it has just the thing to relieve the painful legs of tired queuers.

    The new system of self-driving chairs is designed to detect when someone at the front of the queue is called, and automatically move everyone else one step forward in line.

    The new invention is shown in a company video, which shows a busy restaurant with customers waiting outside. In the video, diners are sitting in a row of chairs, but will not have to stand when the next hungry diner is called to a table. Instead, the chairs, equipped with autonomous technology that detects the seat ahead, move along a path toward the front of the line. When the person at the front of the queue is called, the empty chair at the front can sense it is empty and so moves out of line. Cameras on the remaining chairs then sense the movement and follow automatically.

    “The system, which is similar to the kind used in Nissan's autonomous vehicle technology, will be tested at select restaurants in Japan this year," Nissan said. "It appeals to anyone who has queued for hours outside a crowded restaurant: it rids the boredom and physical pain of standing in line,” Nissan added.

    Although Tokyo has some 160,000 restaurants, long queues are not uncommon. Chosen restaurants that meet the criteria will be able to show the chairs outside their restaurants next year. Nissan also released a short video showing the chairs being used in an art gallery, moving slowly in front of the various paintings to let viewers appreciate the art without the need to stand up.

    The world maps will soon be altered to reflect an eighth continent! Dubbed "Zealandia" the landmass that lies east of Australia covers 4.9 million km. Over 94 percent of it is submerged (淹没的) in the southwest Pacific Ocean, with just the islands of New Zealand and New C aledonia visible above sea level.

    To be clear, the underwater land is not a recent find. Researchers have known about its existence since 1995 when Bruce Luyendyk discovered and proposed an eighth continent that he called Zealandia. At the time, the area was dismissed as a collection of islands and land fragments (碎片), or at the most, classified as a micro continent—a landmass of continental crust that is not geologically connected to the nearest continent, in this case, Australia.

    However, after observing the areas features on an underwater topography map, New Zealand geologist Nick became convinced that Zealandia is a continent. Mortimer says that while Zealandia is much smaller than our seven continents, at over half the size of Australia, it is unfair to classify it as a microcontinent. The geologist argues, “If you could pull the plug on the world's oceans, then Zealandia would probably long ago have been recognized as a continent.”

    Geologist Christopher Scotese argues that too much of the landmass is underwater, asserting it's "almost a continent the way Pluto is almost a planet." Richard Ernst, a geologist, proposes coining a new term minicontinent—for Zealandia. He thinks this is perfect given that it is too large to be called a microcontinent and too small to be classified as a full-sized continent. Given that there is no international panel to decide the fate of Zealandia, its future as a continent is uncertain. Mortimer hopes that if supporters start using the term Zealandia, it may eventually catch on. Whether that happens remains to be seen, but for now, we will have to be satisfied with just seven continents!

"What should I learn to stay excellent?" {#blank#}1{#/blank#} , but it is still worth thinking—both for the professional benefits and the complete joy of learning something new. Here is a look at sone skills that will surely benefit you. 

Self-management

Self-management is your ability to manage behaviors, thoughts and emotions. It is a way that better serves you and your work. Rules of self-management usually include: How to create and keep a calendar; {#blank#}2{#/blank#} ; How to do a weekly review; How to focus deeply. 

Logic and reasoning

Logical（逻辑） thinking can be extremely powerful for making better decisions and solving problems. However, most of us receive little training in this area in school. {#blank#}3{#/blank#} .

How to do exercise

You can just pick an activity you enjoy and do it regularly. Try different things and see what you enjoy. {#blank#}4{#/blank#} . The best program is the one you'll actually hold on to.

F. And remember that there's no such a thing as the "best" exercise program

G. But having logical thinking in your mental "toolbox" can be very useful
