In the _________past, the Antarctic was covered by plants.(遥远的)
In Antarctica, you learn not to take anything for granted. Everything people depend on has to be shipped or flown into the continent. Why? There are no farms on the icy continent. There are certainly no cows, pigs or chickens. As for drinking water, special systems and a great deal of energy are needed to take the salt out of seawater to make it useable.
Then there is the matter of waste. The US Antarctic Program is committed (致力于) to reducing its impact- or footprint--on the Antarctic environment. That means that every bit of garbage a person might produce in a day has to be transported off the continent. That's true whether it's the wrapper from your candy bar, the green beans you didn't want to eat or the paper towels you used to wipe your hands,
McMurdo Station has put into place technology that helps it reduce its footprint. It starts with energy. The US research base has partnered its nearby neighbor, New Zealand's Scott Base, to share energy produced from three large wind turbines. Scott Base gets 100% of its power from wind, says Ron Blevins, manager at a power plant, while the American base gets about 35% of its energy from wind. The much larger US base uses oil-fired generators(发电机) to supply the rest of its energy needs. The waste heat produced by the generators is then used to warm many of its buildings.
The McMurdo base also has a wastewater treatment plant. Yubecca Bragg, an organic farmer, manages the treatment plant. Bragg explains that treatment depends on allowing microorganisms(微生物) to break down the waste until the liquid part of the waste can be safely released into the ocean. Between 150, 000 and 180,000 pounds a year of the remaining solid waste is packed into containers and sent back to the US.

Last Monday, we were having our Chinese class while the teacher suddenly slip and fell. We were all worried about her. One of the boy carried her on the back, under the help of some others, to the clinic immediately. It turned out that her right leg was breaking and she had to stay in hospital. The following day, we went to visit her with flowers and fruit. Seeing her laying in bed with leg wrapped in bandages, we felt sorry for her and hoped that she would recover soon. Lucky enough, this Thursday she returned back to the class in a wheelchair to give us lessons. We were both deeply moved and proud of having such a responsible teacher.

Michael Aldrich（the UK）
Online shopping was invented and pioneered by Michael Aldrich in the UK. In 1979 he connected a television via a telephone line to a real-time multi-user transaction(交易)processing computer. He sold mainly Business-to-Business systems. There were a number of significant world firsts with new applications in several business fields.
Jeff Bezos（the USA）
Jeff Bezos defined online shopping and rewrote the rules of commerce. Tim Berners-Lee invented the World Wide Web server and browser（浏览器）in 1990. In 1994, Jeff Bezos read an article about how the World Wide Web was growing by 2,300 percent a year. He knew he had to tap into such a great potential for commerce. On July 6, 1995, Bezos launched Amazon.com, which operated out of the garage of his two bedroom home in suburban Seattle, Washington. With almost no publicity, sales took off immediately. The company has now expanded into dozens of product categories, forcing the world’s biggest retailer（零售商）to rethink their business models, and finally changing the way people shop.
Jack Ma（China）
As a child, Jack Ma was bad at maths but fascinated by English. He travelled to the United States in 1995 as a translator to help a Chinese firm recover payment. The attempt failed. But a friend in Seattle showed Ma the Internet, and an idea began brewing.
In 1999, Mr Ma gathered 17 friends and founded Alibaba in his apartment in Hangzhou. Alibaba’s model was simple: allow small and medium-sized Chinese companies to find global buyers they would otherwise only be able to meet at trade shows. It works brilliantly. Alibaba’s sales are now more than those of eBay and Amazon combined.
