More than 3,500 people have successfully climbed the 8,844m mountain, and more than a tenth of that number reached the peak just over the past year. As more and more people try to test themselves against Qomolangma, many a time the mount can be very crowded. Climbers have complained about waiting for hours in the bottlenecks（狭窄路段） on the way to the peak. If bad weather strikes, climbers can and do die.But the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of gear—much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's tallest rubbish 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 not only dangerously crowded but also badly polluted."But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountaineer 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 changed the cans and oxygen tanks—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 off the mountain.1.What do we learn about the bottlenecks on the way to Mount Qomolangma's peak?A.
