[Q]: Article: Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower. But on Thursday, Viesturs became the only American to climb to the top of the world's 14 highest mountains. His last hike was up Mount Annapurna, in Asia's snowcapped Himalayas. At 26,545 feet, its peak is the 10th highest in the world. It is the mountain that inspired him to start climbing. "It tends to be the trickiest, the most dangerous," said Viesturs. "There's no simple way to climb it. There are threatening avalanches and ice falls that protect the mountain." In high school, Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna. Herzog's story was of frostbite and difficulty and near-death experiences. Viesturs was right away. Viesturs got his start on Washington's Mount Rainier in 1977, guiding hikes in the summer. Fifteen years ago, he set out to walk up to the world's highest peaks. Finally, he's done. The pioneering climber talks about mountains as if they were living creatures that should be treated with respect. "You have to use all of your senses, all of your abilities to see if the mountain will let you climb it," said Viesturs. "If we have the patience and the respect, and if we're here at the right time, under the right circumstances, they allow us to go up, and allow us to come down." What's next for a man who can't stop climbing? "I'm going to hug my wife and kids and kind of kick back and enjoy the summer," says Viesturs. But for a man who's climbed the world's 14 tallest mountains, he will probably soon set off on yet another adventure.

[Q]: Article: Several years ago I worked in an office, which had a locust tree growing outside the window. It had grown into a tall tree and must have been there for a long time. The tree blocked the view and made the office seem dull, unfortunately this happened to be the room assigned to me and I was depressed by it for quite some time. When the first spring came, everything was green except the locust tree. Secretly, I was very happy because I had thought it had died. One morning when I opened the window for fresh air, I unexpectedly smelt a familiar sweet scent floating into my office but I couldn't name it. Suddenly, I realized it was the locust tree! The tree that I thought dead was blossoming in full glory. From then on, I usually came to the office very early to see dew forming on the locust tree blossoms and every year was eager to see spring again. During summer, the green leaves provided shade protecting me from the harsh sunlight, but allowing enough light in to make it pleasant. In autumn, the leaves turned into many different color1s. Its beauty touched my soul. Many times I thought to take photos but never did. Then I had to leave in a hurry. Later in life it became a great regret that I had not done so. Actually, many times in our lives, we think we own something, therefore we don't cherish it. We don't feel regretful until we lose it one day! Moreover, sometimes, we have to accept the things we don't want and need to discover the hidden beauty to find unexpected joy!

[Q]: Article: While students in Hainan are quite used to clear skies, Beijing teenagers are not so lucky. As another warm winter approaches, the city can expect the normal clouds of smoke caused by air pollution. But things could start to get better soon. The government is co-operating with a US- based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel vehicles ( ) by 40 per cent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them. "We encourage the development of public transportation. But at the same time we need to reduce pollution from them," said an official. Efforts are being made to improve the capital's environment with tighter controls on emissions . Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed. Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index gave just 100 days as good. "I am glad to see an improvement," said a Senior 1 boy living in the northwest of Beijing. "Compared to other places, the air quality of Beijing is still worrying though. I hate the pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn't see a car only metres away from me in frog." In early October, the skies were covered by such a thick fog that a display show by the visiting French air force was called off. Rapid development, industry, traffic fumes and sandstorms from the desert all contribute to the city's bad air.
