The word was also found in another 21 languages. While there were subtle differences in each country, all sounded basically the same.

　　This is surprising because normally unrelated languages will use very different words to describe the same thing. For instance, the Japanese for dog is "inu", while the French is "chien".It is thought that

languages around the world have developed their own version of "huh?" because the sound is quick and simple to form, as well as being easily understood.

　　The researchers, said that it might seem unimportant to carry out scientific research into a word like "huh?" but in fact this little word is an essential tool in human communication. They also have an answer for those who claim that "huh?" isn't a word. They say that it qualifies because of the small differences in its pronunciation in different languages. It also can be considered a word because it's something we learn to say, rather than a grunt or cry that we are born knowing how to make.

　　Since Edmund Hillary and Tenzing Norgay climbed Mount Everest, Mount Qomolangma's peak is no longer a lonely place and is turning into a trash heap.

　　So far, more than 350 climbers have successfully reached the peak. And they have complained about waiting for hours in the bottlenecks (狭窄路段) on the way to the peak, a situation that isn't just uncomfortable - it's cold and windy up there - but downright dangerous. If bad weather strikes, climbers can die.

　　As a matter of fact, the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of gear-and much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's largest dump. Here's mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: "The two standard routes, the Northeast Ridge and the Southeast Ridge, are disgustingly polluted with oxygen cans and torn tents everywhere."

　　But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountianeer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since 2008. So far they've collected over 13 tons of garbage.

　　Some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They've transformed the cans and oxygen tanks-and in one case, part of the remains of a helicopter-into 74 pieces of art that have already gone on exhibition in Nepal's capital. Part of the profit from sales will go to the Everest Peakeers Association, which has helped collect tons of rubbish on the slopes of the mountain.
