One of the world’s most dangerous sports is mountain climbing and one of the most popular places for this is the Himalayas. The Himalayas run along the southwestern part of China. Of all the mountains, Qomolangma rises the highest and is the most famous. It is 8,844.43 meters high and so is very dangerous to climb. Thick clouds cover the top and snow can fall very hard. Even more serious difficulties include freezing weather condition s and heavy storms. It is also very hard to take in air as you get near the top. The first people to reach the top were Tenzing Norgay and Edmund Hillary on May 29, 1953. The first Chinese team did so in 1960, while the first woman to succeed was Junko Tabei from Japan in 1975. Why do so many climbers risk their lives ? One of the main reasons is because people want to challenge themselves in the face of difficulties. 1. succeed in doing sth 成功做某事 2. succeed with sth 在某方面获得成功 1. risk one’s life 冒生命危险 2. take the risk of doing sth 冒险做某事 The spirit of these climbers shows us that we should never give up trying to achieve our dreams. It also shows that humans can sometimes be stronger than the force s of nature . 动词，强迫 force sb to do sth = force sb into doing sth They forced him to leave the town. = They forced him into leaving the town.

Lin Wei and the other panda keeper s are preparing the milk for the baby pandas’ breakfast. At 9:00 a.m., they find that most of the babies are already awake and hungry. When the babies see the keepers, they run over with excitement and some of them even walk into their friends and fall over ! “They’re so cute and lovely. I take care of them like they’re my own babies. I wash, feed and play with them every day. They’re very special to me.” Lin Wei loves her job, but it is a difficult one. Pandas do not have many babies, maybe only one every two years . The babies often die from illness es and do not live very long. Adult pandas spend more than 12 hours a day eating about 10 kilos of bamboo. Many years ago, there were a lot more bamboo forests and pandas in China, but then humans started to cut down the forests. Scientists say there are now fewer than 2,000 pandas living in the remaining forests. Another 200 or so live in zoos or research centers in China and other countries. An education program in Chengdu teaches children in cities about pandas and other endangered animals. They send people to schools to tell children about the importance of saving these animals. The children sing songs or make artwork about pandas and other wild animals. Teaching children is one way to help save pandas. The Chinese government is also planting more bamboo trees so there will be more forests for pandas to live in. We all hope that in the future there will be a lot more pandas than now. 10: 12: 200: 2000: Adult pandas eat 10 kilos of bamboo a day. Adult pandas spend more than 12 hours eating a day.
