Centuries ago, however, crossing the open seas required thorough and accurate planning, handmade boats, and courage. Scientists and historians have long been looking for clues to explain who crossed which oceans first. When it comes to the trip between Polynesia (玻利尼西亚中太平洋群岛) and South America, chickens may have been among the first ocean voyagers, according to new evidence. ‎ ‎ After studying an ancient chicken bone, anthropologists (人类学家) from the University of Auckland in New Zealand now say that people and chickens traveled from Polynesia to what is now Chile (智利) by about 620 years ago. By then, the Inca people were already living in South America, but the Polynesians would have been the first to get there by sea. Previous theories claimed that European explorers and their chickens sailed to South America first -- but those voyagers didn't arrive until about a century later.‎ ‎ In 2002, archaeologists dug up 50 chicken bones from a site in Chile called El Arenal. The team from New Zealand analyzed one to these bones. According to their calculations, the bone is about 650 years old.‎ ‎ The researchers also compared the genetic material, or DNA, from the South American chicken bone with DNA from 11 chicken bones that had been found on the Polynesian islands of Tonga and American Samoa. These islands are 6,000 miles west of Chile. The bones found on the Polynesian islands are been 600 and 2,000 years old.‎ ‎ Results of the comparisons showed that the chicken bones from both the Polynesian and South American sites had part of DNA in common. The researchers found the same part of DNA in feathers of two living chickens in Chile that belong to a modem breed that lays blue eggs. That DNA evidence suggests a close relationship among the chickens.‎ ‎ "However, the weight of scientific evidence is now behind the hypothesis (假设) that it was seafaring ( 航海) Polynesians who sailed from the islands to South America and returned," says archaeologist Patrick V. Kirch of the University of California, Berkeley.‎ ‎41. What is the passage mainly about?‎ ‎ A. It was difficult for ancient people to travel between Polynesia and South America.‎ ‎ B. The first people who lived in Chile and Polynesia.‎ ‎ C. Valuable chicken bones have been found in Chile.‎ ‎ D. Chickens -- the first to travel between Polynesia and South America.‎ ‎42. When did the first European explorers reach South America?‎ ‎ A. About 620 years ago. B. About 2.000 years ago.‎ ‎ C. About 600 years ago. D. About 520 years ago.‎ ‎43. People found that chickens were among the first to travel from Polynesia to South ‎ America by ___________.‎ ‎ A. comparing the colors of eggs laid by chickens from the two places ‎ B. comparing the DNA of chicken bones dug up on the Polynesian islands and that of the chicken bones from South America ‎ C. studying some previous theories ‎ D. asking the natives of South America ‎44. What do we learn from the passage?‎ ‎ A. European explorers and their chickens were the first to sail to South America.‎ ‎ B. Chickens in South America have the same ancestors as those in Polynesia.‎ ‎ C. In ancient times, a 6,000-mile channel separated Polynesia from South America.‎ ‎ D. Before the Polynesians arrived in South America, the Inca people had lived there. '‎ ‎45. Why was it difficult for people to travel across the oceans in ancient times, according to the passage?‎ ‎ 1) It was difficult to take many chickens as food.‎ ‎ 2) People had difficulty making careful and detailed sailing plans.‎ ‎ 3) People lacked maps and the knowledge of weather forecasting.‎ ‎ 4) People had to make boats by hand.‎ ‎ 5) It took great determination to cross an ocean.‎ ‎ A. 1) 4) 5) B. 2) 3) 4) C. 2) 4) 5) D. 1) 2) 3) ‎ ‎4. 读写任务 阅读下面的短文，然后按照要求写一篇150词左右的英语短文：‎ ‎ I like water gymnastics best for many reasons.

Most importantly, I like the great music and their amazing performance in water ballet. When I watch this Olympic sport, I can learn their professional techniques in swimming.‎ ‎ For example, swimmers' performance is evaluated based on a series of predetermined elements. Arm sections and figures, similar to those of figure skating, are also required, and all elements must be presented in a specific order. Because synchronized (同步的) swimming routines require exceptional breath control, judges also take into consideration the ability of the swimmers to preserve the illusion (n.幻想) of effortlessness while holding their breath for up to two minutes.‎ ‎[写作内容]‎ ‎ 1．以约30个词概括短文的要点。‎ ‎ 2．然后以120个词写一篇英语短文谈谈你喜欢的体育运动项目，并包括如下要点：‎ ‎ 1)你喜欢哪一种体育运动项目。‎ ‎ 2)说明你的理由。‎ ‎ 3)该体育运动项目对你的日常生活造成的某些影响和感想。‎ ‎[写作要求]‎ ‎ 1‎ ‎．作文中可使用自己的亲身经历或虚构的故事，也可以参照阅读材料的内容．但不得直接引用原文中的句子；标题自定。‎ ‎ 2．作文中不能出现真实姓名和学校名称。‎ ‎[评分标准]概括准确。语言规范，内容合适，篇章连贯。‎ ‎[写作辅导]‎ ‎ 1．写作有可能用到的主要短语和单词：羽毛球badminton，排球volleyball，足球football，体操 gymnastics，网球tennis，跳高high jumping，射击／射箭5hooung，游泳swimming，棒球baseball，最喜欢的favourite，表演performance，对……影响have an effect on sth/sb. ‎ ‎ 2．本文的概要必须包含以下要点：I like water gymnastics best for many reasons. / Especially, I am fond of water gymnastics for two major reasons - the amazing movements and those sexy and those very beautiful women swimmers./ For example, swimmers' performance is evaluated based on a series of predetermined elements.‎ ‎ 3．本文要注意，概要一定要根据文段的时态来写。同时，绝对不能抄袭原文的句子：文章中描述的是你喜欢哪一种体育运动项目和理由、感想等等，都属于评论性文字和结论性的观点，故多用一般现在时或一般将来时态：‎ ‎________________________________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ ‎________________________________________________________________________________________________‎ 答案:‎ ‎ I Have Fallen in Deep Love with Football ‎ In the above passage, the writer tells us the reasons why he likes water gymnastics, such as the amazing movements and those sexy and those very beautiful women swimmers.‎ ‎ Football is a very popular sport in the world and I think I have fallen in deep love with it, which makes me feel so crazy.
