单选题Chinese knotting was originally developed not as an art form in itself but was used to attach accessories, such as jade pendants (玉坠), to clothing. Today, it is considered beautiful in its own right, thanks to people such as Taiwan's Chen Xiasheng. Chen, who was born in 1939, has studied Chinese knotting since the early 1970s and was one of the first people to introduce the centuries-old craft--with the help of books and exhibitions--to both Chinese and Western audiences, helping it become known around the world as Zhongguojie. On Wednesday, she was honored for her contribution to Chinese knotting at the Outstanding Fashion Personages Award Ceremony 2011, which were held in Beijing. "These days, so many domestic designers are scrambling for ideas from Western countries, despite the fact that we already have such elegant, beautiful knotting," Chen said. "Why not use Chinese knotting as a fresh element in clothing design?" Her affection for knotting developed out of her interest in ancient clothing when she worked as a researcher at the Taipei Palace Museum between 1972 and 2001. She said Chinese people have been using knots for decoration since the 5th century BC and a wide range of knots have been developed over the years. "The archaeological significance of this is you can figure out when an antique was made based on the decoration and knotting it has," Chen said. She said knowledge of the knots helped her when she was a researcher but she was not satisfied to keep them on paper and wanted to see what they looked like in bright colors and experience the way they felt. She used information about Chinese knotting available at the time, such as from ancient books, carvings and paintings, to start to make knots. "I copied all the knots I saw on paintings. Then I analyzed their structure and found that all the knotting was formed by variable arrangements of some 'basic cells'," Chen said, adding that her college education in mathematics helped her make sense of them. Chen said 14 "basic cells" were used in various combinations. "This is so different from knots found in Western countries, because they have only two basic types." "In the West, people use very simple knots to form complex shapes, such as a tree or a dog, but the knots themselves are not decorative. In contrast, the Chinese knots themselves are ornamental," she said, pointing to a necklace made of Chinese knots and small jade rings. The necklace is one of Chen's favorites and stands out among the hundreds she has made during the past four decades. Chen has used various materials, including cotton thread, silver thread and silk, to make and create new shapes. "Based on the basic knots, you can create countless shapes," she said. At the same time, she has written a series of books that have been sold around the world that tell others how to tie such knots. In publishing the books, she gave a general name to Chinese knots--Zhongguojie--and called each specific knot by its own name. Thanks in part to the popularity of her books and the general name she has given to the knots, Chinese knots have become a symbol of China and are becoming more popular, not only domestically but also overseas.

单选题The idea of a vacuum cleaner originates from the 19th century. The first vacuum cleaners had to be operated manually. Two persons were needed for this: one to operate the bellows and the other to move the mouthpiece over the floor. The dust was blown into the air. On August 30th 1901 Hubert Cecil Booth, a British engineer, received a British patent for a vacuum cleaner. It took the form of a large, horse-drawn, petrol-driven unit which was parked outside the building to be cleaned with long hoses being fed through the windows. Until then vacuum cleaners blew the dust away, but Booth came up with the idea of sucking away dust, instead of blowing. Furthermore Booth equipped his cleaner with a filter, which kept the dust in the machine. All modem vacuum cleaners are based on Booth"s principle. As Hubert Booth, demonstrated his vacuuming device in a restaurant in 1901, two Americans introduced variations on the same theme. Corinne Dufour invented a device that sucked dust into a wet sponge. David E. Kenney"s huge machine was installed in the cellar and connected to a network of pipes leading to each room in the house. A corps of cleaners moved the machine from house to house. In 1903 wealthy society ladies threw "vacuum cleaner parties". Guests sipped their tea and lifted their feet for Booth"s uniformed attendants to vacuum the carpet. After giving a vacuum demonstration at the Royal Mint, Booth, on leaving, was promptly stopped by the police. He had forgotten to empty the dust bag, which contained a large quantity of gold dust from the Mint. In 1910 Professor Stanley Kent of University College, Bristol found 355,500,000 living organisms in just one gramme of dust extracted from Marlborough House, the home of HRH The Princess of Wales. In 1907, James Murray Spangler, a janitor in a Canton, Ohio department store, deduced that the carpet sweeper he used was the source of his cough. He tinkered with an old fan motor and attached it to a soap box stapled to a broom handle. Using a pillow case as a dust collector on the contraption, Spangler invented a portable electric vacuum cleaner. He then improved his basic model the first to use both a cloth filter bag and cleaning attachments, and received a patent in 1908, and formed the Electric Suction Sweeper Company. One of the first buyers was a cousin, whose husband, William H. Hoover, later became the president of the Hoover Company, with Spangler as superintendent. Hoover"s improvements resembled a bagpipe attached to a cake box, but they worked. Sluggish sales were given a kick by Hoover"s 10 day, free home trial, and eventually there was a Hoover vacuum cleaner in nearly every home. John Thurman started a horse drawn (door to door service) vacuum system in St. Louis, similar to Booth"s. His vacuuming services were priced at $4 per visit in 1903. He invented his gasoline powered vacuum cleaner, in 1899 and some historians consider it the first motorized vacuum cleaner. Thurman"s machine was patented on October 3, 1899 (patent #634,042).
