The world’s longest cave system is an enormous network of 420 miles of twists and turns, with limestone (石灰岩) falling from the ceilings in drops.
Mammoth Cave National Park preserves this unique and historical natural wonder. As large as the limestone cave system is, park officials, estimate there may be another 600 miles of cave passageways that have yet to be explored. The incredible rock formations have resulted in the park being recognized as a World Heritage Site, thanks to its extraordinary size and scientific importance –– making it one of only 13 natural US sites with that title.
The caves were created naturally by the process of limestone wearing away. Rain and rivers slowly break down and shape soft limestone, which creates the vast underground network. Not only are they an amazing destination to visit, but the system also provides drinking water for roughly 40% of the US population, and they’re of historical significance too.
The caves act as a time capsule that preserves over 5,000 years of human history — and the caves’ first explorers were Native Americans, who mined the upper levels of Mammoth Cave. Thanks to the cave system’s atmosphere and natural protection from any kind of human disturbance, the archaeological (考古的) sites have been left in great shape.
Mammoth Cave was established as a national park thanks to strong local support. Back in the 1920s, Secretary of the Interior Hubert Work created the Southern Appalachian National Park Commission in 1925 to survey proposed park sites, including the caves. After years of work acquiring the land for the park, as well as building roads, trails (小径), and public facilities, Mammoth Cave National Park was established on July 1, 1941. The park now receives around 2 million visitors a year, with roughly a quarter taking a tour of the caves –– everything from a cultural tour to the more adventurous climbing tours on offer. The cave supports more than 130 wildlife species, such as the eyeless cavefish, which has adapted to the lightless environment by no longer growing eyes, and the cave crayfish.

【推荐1】All young people dream of travelling the world. They are excited and very eager to see new sights. However, they have little idea how they would really do it if given the chances. Because their knowledge of geography is quite limited, they seldom know much about the places they wish to visit or how they would get there.
Already hundreds of thousands of Chinese student tourists are visiting these places — Wuyi, Lhasa, Lijiang, Dali, Vientiane and Phnom Penh. Indeed, these students will soon be the most travelled generation in China’s long history. The World Tourist Organization predicts that a quarter of a century from now the number of Chinese tourists going abroad will be twenty times what it is today. The largest percentage of these tourists will visit Southeast Asia. Not all Chinese who travel abroad will be tourists, however. More and more youths are deciding to volunteer their skills in this region, much like their peers in the Peace Corps and VSO.
Critical thinking skills required include planning for a trip and solving problems after the trip has begun. The focus is on how to read an atlas (地图集) to make travel plans and how to find ways of travelling. An atlas offers a wealth of information about geography and is one way to increase students’ awareness of their global environment. The use of an atlas especially addresses the needs of students with different visual and spatial (空间的) learning styles.

【推荐2】By the time Joy Ryan, a US grandma, turned 85, she had never seen the ocean or mountains. For Joy, trips to the local fishing area with her husband were about the farthest place she had ever gone, even if she loved watching the Travel Channel.
But one day Joy’s grandson, Brad Ryan, discovered that he and his grandma had a common interest in their love for traveling, when they began to visit the American great outdoors together.
Brad said, “When I learned my grandma had never seen the great wildernesses of America—deserts, mountains and oceans, I thought there was something I needed to do.” It was after taking his grandma out of Ohio on a visit to the Great Smoky Mountains National Park that he came up with the idea of visiting all the 63 US national parks with her to create inspiring memories.
Going to all the 63 US National Parks is a huge achievement even for a much younger adventurer (冒险家). Brad said his grandmother’s physical strength (体力) grew with their trips. For example, his grandma went water rafting (漂流) at 91, with class three rapids and when walking at the New River Gorge National Park in West Virginia, she broke the record by almost a decade!
It wasn’t always like this, however. Joy was so wobbly (不稳的) on her first trip, challenged by her balance. A group of college students clapped their hands when she reached the top of a path they were following.
Joy broke her age limitation (限制) and at the age of 93, she made history as the oldest living person to visit every US National Park. Joy believes it’s the mix of hopefulness, willpower, and the good health that gives her strength.

【推荐3】I have just arrived in a country where I don’t know the language, where I have no family roots and where I find myself all alone. It may sound frightening. But let me tell you a little secret: it is not.
When you travel abroad by yourself for whatever reason—exchange program, internship, volunteering, or simply as a tourist—a new and fascinating world will open up for you. A world you would have never been able to see if you had just stayed at home.
People from a different country are not aliens. They are simply people like you who happened to be born in another region. They have pretty much the same wishes and worries as people from your own country.
I know that you see a lot of news on TV saying terrible things people do all the time. Your family may have spent a great deal of time telling you not to trust strangers. However, when you travel alone you will realize that people are just as good as you. Everyone is just leading their lives, working, studying and having a good time with their friends. Most people will be happy to help you and get to know you.
Maybe in the past when you would need months to travel from one place to another, traveling could be expensive. Nowadays, the world is just so connected that it is perfectly possible to find cheap flights, accommodation for all budgets and cheap and quality food.
You will get lost, but it’s fine! I can’t even count how many times I didn’t know where I was going or how to find the right direction. Everything looks great on Google maps, but sometimes your phone will die or your data will end. Just calm down. Go to a store or stop someone in the street and ask! Or simply walk around and be curious.

【推荐1】If you think about World Heritage Sites, you probably think of places connected with ancient art and culture, historical buildings and monuments. And of course, many of these are on the World Heritage List (WHL) (世界遗产名录). But the WHL contains a lot of sites that are not so obvious. Let’s look at a few of them.
Robben Island in South Africa
This island was used through the centuries as a prison, a hospital and a military base. But it’s probably most famous as a maximum-security prison for political prisoners in the twentieth century. Nelson Mandela was one of its most famous residents. The WHL says it represents “the triumph of democracy (民主) and freedom over oppression and racism”.
Borders of France and Spain
This is an area of great natural beauty and the mountains have many interesting geological formations. But it is also an area of small farms. People there still use a type of agriculture (农业) that used to be common in mountainous areas of Europe but that has almost completely disappeared in modern times.
The city of Brasilia, Brazil
Brasilia is a capital city that was created from nothing in 1956. The WHL calls it “a landmark in the history of town planning”. The different areas of the city and the buildings themselves were all designed at the same time carefully. Every part of the city shows the ideas of the planner and architect.
Simien National Park, Ethiopia
Simien National Park was one of the first sites to be listed in 1978. It is one of the highest mountainous areas in Africa, and the WHL calls it “one of the most spectacular landscapes in the world”. It is also important for its wildlife. The population of some rare animals is getting smaller and smaller.
1. Which of the following sites was listed on the WHL for its political symbol?A.Simien National Park, Ethiopia. | B.The city of Brasilia, Brazil. |

【推荐2】If you’re a lover of the great outdoors and fancy yourself as a bit of a discoverer, then you’ll want to know about the best national parks in the world. National parks are full of wonders. Exploring one is your chance to get back to nature.
Etosha National Park, Namibia
Etosha means “great white area”, which refers to the park’s huge salt area. When it rains, the water pools attract hundreds of thousands of pretty flamingos (火烈鸟) to the park. And yet there is more to Etosha National Park than flamingos. Expect to see lions, elephants, leopards and two kinds of zebra as you venture around the park.
Yellowstone National Park, United States of America
You will find Yellowstone National Park atop a volcano hot spot in Wyoming, but the thing that will explode will be your mind as you immerse yourself in the dramatic canyon, lush forests, and alpine rivers. Yellowstone is one of the best national parks in the world to study the geological activity of the Earth.
Göreme National Park, Turkey
Prepare to lay your eyes on volcanic landscapes situated in a UNESCO World Heritage Site at Göreme National Park in Turkey. Hike the high hills, explore nearby villages and witness stunning multi-colored cliffs formed from basalt. Göreme National Park is one of the best national parks in the world for hot air ballooning.
Caingorms National Park, Scotland
The largest national park in the United Kingdom, the Cairngorms provide exceptional wildlife and birdlife —including some of the rarest birds of prey in Europe. Hill climbers will be kept busy with the 55 munros (a mountain peak higher than 3000 feet) in the park.

【推荐3】Life in Death Valley
Death Valley is a huge place, extending more than 225 kilometers across the southern part of California into the neighboring state of Nevada. As beautiful as this place is, its name provides evidence of very real danger.
In many areas of Death Valley, it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This has created unusual and beautiful rock formations, with colors of red, brown, gray, yellow and black. In other parts of Death Valley, there are lines in the rock. The lines are evidence of the past presence of water.
Much of Death Valley is flat and extremely dry. In some areas the ground is nothing but salt. However, it would be wrong to think that nothing lives in Death Valley.
Throughout history, Native Americans found ways to survive in Death Valley. Rock art and other remains show that humans lived in the valley as far back as 9, 000 years ago. Nowadays, more than one million people visit it each year.

【推荐1】Happy Rain on a Spring Night
Good rain knows its time right;
It will fall when comes spring.
With wind it steals in night;
Mute, it moistens each thing.
O’er wild lanes dark cloud spreads;
In boat a lantern looms.
Dawn sees saturated reds;
The town’s heavy with blooms.
(Translated by Xu Yuanchong)
(Notes:mute无声的;moisten使……湿润;lane小路;loom隐现;saturated渗透的;dawn黎明;)
When Tang Dynasty poet Du Fu (712-770) wrote this poem, he was living in Chengdu. Sometimes he went to farm in the field. The poem shows his care for farmers.
The very first word, “good”, shows the poet’s joy and love for the spring rain. The rain is good indeed, as it “knows” the proper time to come. Here the poet uses personification (拟人), as if the rain were smart enough to know that it should come in time for the farmer’s busy plowing (农耕) season.
When the rain comes, it appears during the night without making any noise. Unlike the thunder (雷) and lightning of summer storms, the quiet spring rain makes its contributions without seeking (寻求) to be known.
In the night sky, the clouds look dark and heavy, indicating (暗示) that there will be enough rain during the night. Then the poet imagines: tomorrow morning, all of the flowers in the city will bloom (盛开) after the rain.

【推荐3】How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless(无线的) connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart and fun,” Serval says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, from $99 to $199, and the U.S. is the first target market.
Serval says that one day, it’ll be possible to take the place of the brush one the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.
