阅读理解A (原创) 体裁：说明文 话题：世界与环境 难度：★★★☆☆ Scientists recently announced the discovery of a small, birdlike dinosaur from China which had unusual, colorful feathers. The scientists named the colorful dinosaur Caihong, which lived 161 million years ago during the Jurassic Period of earth's history, the Mandarin word for rainbow. They discovered the nearly complete and almost entirely undamaged fossil in Hebei Province.(第一段中的关键词discovery是答题线索)
(第一句说明羽毛的形状和颜)Microscopic structuresin the fossil suggest that the creature had wide, shinyfeathers, mostly covering the dinosaur's head and upperbody, while much of its body had dark feathers. Chad Eliason is an evolutionary biologist with the Field Museum in Chicago, Illinois. He helped write the study announcing the discovery in the scientific publication Nature Communications. Eliason told the Reuters news service that the discovery “短期融资券管理办法suggests a more colorful Jurassic World than we previously imagined.”
The scientists used powerful microscopes to identify the remains of the cell structures responsible for the apparent color of the feathers. The shape of those structures appears to have influenced what color the feathers would have. Roundshaped structures in the Caihong fossil show that it had feathers similar to that of a modernday hummingbird.
The dinosaur had many birdlike qualities. But researchers doubt if it could actually fly. Its feathers could have served the purpose of gaining the attention of sexual partners while also providing protection from heat and cold. Caihong was twolegged and had a long, narrow head with sharp teeth. It had boney crests above its eyes, and it hunted other smaller animals for food.
Scientists say many dinosaurs had feathers. Birds evolved from small feathered dinosaur
s near the end of the Jurassic Period. Caihong had two kinds of feathers, and was the earliestknown creature with feathers that did not have the same shape on both sides. This is a physical
quality that modern birds have and use to direct themselves while flying.
The unevenly shaped feathers on Caihong were on its tail. This suggests that tail feathers, not arm feathers, were first used to improve movement through the air in flying dinosaurs, scientists said.

The traditional Chinese lunar calendar divides the year into 24 solar terms. Winter Solstice (冬至), the 22nd solar term of the year, begins this year on Dec. 22 and ends on Jan. 5.
On the first day of Winter Solstice, the Northern Hemisphere experiences the shortest day and the longest night in the year, as the sun shines directly at the Tropic of Capricorn. From then on, the days become longer and the nights become shorter. The Winter Solstice also marks the arrival of the coldest season in the year.
There was a saying that went in ancient China, “The Winter Solstice is as significant as the Spring Festival.” As early as the Zhou Dynasty (c.11th century—256BC), people celebrated the first day of the Winter Solstice, which was also the first day of the new year. The Winter Solstice became a winter festival during the Han Dynasty (206BC—220AD). The celebratory activities were officially organized. On this day, both officials and ordinary people would have a rest. During subsequent (随后的) dynasties, such as the Tang (618-907), Song (960-1279) and Qing dynasties (1644-1911), the Winter Solstice was a day to offer sacrifices to Heaven and to ancestors.
During Winter Solstice in North China, eating dumplings is essential to the festival. There is a saying that goes “Have dumplings on the first day of Winter Solstice and noodles on the first day of Summer Solstice.” People in Suzhou, Jiangsu Province, are accustomed to eating wontons (馄饨) in midwinter. According to a legend, during the midwinter feast 2,500 years ago, the King of Wu was tired of all costly foods and wanted to eat something different. Then, the beauty Xishi made “wontons”精致的乐趣 法国完整版 for the king. He ate a lot and liked the food very much. In memory of Xishi, the people of Suzhou made wontons the off
icial food to celebrate the festival.
During the Winter Solstice, Hangzhou residents traditionally eat rice cakes. In places such as Shanghai, people eat tangyuan, a kind of stuffed small dumpling ball made of glutinous rice flour to celebrate Winter Solstice.
