1 . The country’s first national park, Yellowstone, is renaming one of its largest mountains to honor indigenous people after research revealed the man it had been named after helped lead a massacre (屠杀) against local tribes. As part of the park’s 150th anniversary, officials announced the 10,551-foot high peak formerly called Mount Doane is now First Peoples Mountain.
“It is a victory, yes. Is history being rewritten and retold truthfully? I hope so,” William Snell, executive director of the Rocky Mountain Tribal Leaders Council, told NPR. His group helped advise federal officials on the name change. In an email, Snell said the change to First Peoples Mountain couldn't have come at a better time as Yellowstone officials prepare for the park’s anniversary in August.
The peak—along a range on the eastern side of Yellowstone Lake—had been named after Gustavus Doane, who helped lead the Washburn-Langford-Doane exploration in 1870 that eventually led to the park getting federal protection.
But recently, historians uncovered Doane’s role in an attack that left at least 173 Native Americans dead. Known as the Marias Massacre, Doane carried out the attack over the killing of a white fur trader. In writings, Doane cast a favorable light on the attack and even showed off about it for the rest of his life, the National Park Service said last week.
The renaming to First Peoples Mountain is part of a trend to better recognize the roles and contributions of Native Americans. It has also become a priority of the nation’s first indigenous cabinet secretary—the Interior Department’s Deb Haaland, who oversees the National Park Service—and Charles SamsⅢ, the first Native American to serve as that agency’s director.
Across the American West, many iconic representative mountains and other environmental places were named after early white settlers, mostly men and some with terrible pasts.
In Yellowstone, park officials say they may consider further changes to derogatory (贬损的) or inappropriate geographical names in the months ahead.

4 . They' re not the world' s tallest or longest bridges, but a string of river crossings made from tree roots are engineering wonders that contain lessons for modern architects.
The town of Cherrapunji in the Khasi Hills is credited with the world record for annual rainfall of over 75 feet! And in this rainy, wet climate, the rubber fig tree grows with abandon. The tree has a secondary root system that grows up above the ground floor and lets the tree easily grow on top of big stones and even out in the middle of streams. Long ago, the Khasis, a tribe in Meghalaya region, realized they could make use of these roots to their own advantage. By controlling and directing the secondary roots, they have created strong living bridges with which to cross streams and rivers by themselves.
To make a tree grow in a certain direction, the tribespeople use the trunks of a betel nut tree whose middle is got rid of, as a guidance system. The thin, tender roots of the rubber tree are placed so they grow in the direction of the tree trunk rather than fanning out. Eventually, the roots reach the other side of the river and grow into the soil. This process can take well over a decade before the bridge is fully functional and then over time the bridge grows and strengthens. Rocks are placed along the bridge' s sides to improve the footpaths.
Some of these bridges are over 100 feet long and can even support the weight of fifty or-more people at a time. These bridges are used daily by the people of the villages around Cherrapunji and a few are thought to be more than 500 years old. There is even a double decker bridge , known as the “Umshiang Double-Decker Root Bridge", which features two bridges grown right on top of each other. It is thought to be the only bridge of its kind.

5 . The twilight zone (朦胧地带) contains the largest and least explored fish stocks (储备) of the world’s oceans. Ranging from just below 200 metres to 1,000 metres deep, it is an interface between the well-studied sea life in the sunlit zone above and the ecosystems of the darkest territory below. It has a major role in removing carbon dioxide from the atmosphere and storing it for centuries or longer. The twilight zone is also known to the largest migration on Earth. Huge numbers of fishes and zooplankton (浮游动物) move hundreds of metres towards the surface each night to feed, before withdrawing back down at dawn.
Yet the zone is poorly understood — physically, biogeochemically and ecologically. Even the number of organisms that live there remains a mystery, let alone their diversity and function.
It is alarming, then, that this vast ocean domain is at risk in three ways-even before any of the potential consequences are understood. First, the world’s growing population has an increasing need for food. Second, sea-floor mining for minerals and metals could release waste into the region. And third, climate change is varying temperature, acidification and oxygen levels in ways that are likely to affect life there.
The twilight zone is hard Io study. Its organisms are difficult to sample and analyse, being thinly distributed, almost invisible and often fragile. They also live at pressures of up to 100 atmospheres, which poses problems for laboratory-based investigations.
Critics might argue that walers near coasts and above shelves are more deserving of study, given the huge environmental pressures there, as well as their importance to societies. And, of course, they need attention. Sadly, however, it is too late to avoid widespread environmental damage to these inshore regions. Instead, research efforts and local policies must aim at minimizing the worst effects.
By contrast, the twilight zone is almost left in its original condition. Moreover, the majority of it lies beyond national administration. This makes it of common interest and responsibility, and means that global agreement is necessary to manage it.

6 . Mountain
A mountain is a landform that rises high above its surroundings. Taller than a hill, it usually has steep slopes and a rounded or sharp peak. Mountains are rarely found alone.
Some mountains were formed by the activity of volcanoes. Scientists believe that most volcanic mountains are made up of rock that melted deep within earth. The rock rose through Earth’s surface, or crust. It then flowed onto the surface in the form of lava.
Other mountains were formed by movements within Earth’s crust. The theory called plate tectonics explains this type of mountain building. Earth’s crust is divided into huge pieces called plates, which move very slowly. The continents sit on top of the plates and move with them. At times the plates strike against each other, forcing the rock upward. The Himalayas of Asia are an example of this type of mountain chain.
Mountain ranges are natural barriers to travel. Roads are difficult to build across them. Railroads need expensive tunnels to cross even low mountains.
Life is hard in mountain lands. The high places of the world are cold and have little soil, making farming difficult.
| A．Groups of mountains are called ranges. |
| B．However, many mountain areas are vacation spots. |
| C．The lava, along with volcanic dust, built up to form mountains. |
| D．These colder climates strongly affect the ecosystems of mountains. |
| E．Thus the continental crust is normally much thicker under mountains. |
| F．Therefore mountain ranges tend to divide the people on either side of them. |
| G．They were formed when a plate carrying India struck against the Asian plate. |
