Silk was also traded along the coasts of the India Ocean. Ceylon, with⑥ its central position, was the place where Chinese merchants met with Arab merchants and heard about the westernmost lands. Thus, people of the Han Dynasty knew about Africa and had books with description of the kingdoms on the African coast and the Red Sea. In 97 AD, Gan Ying, a Chinese ambassador went to the East Roman Empire over land and returned to Luoyang with a present from an African king-- rhinoceros horns. 众所周知，很早很早以前，非洲就与印度和红海文明有联系。中国的丝绸沿丝绸之路运往印度、中东和罗马去交换香料和玻璃——这些是在中国根本没人知道的东西。沿印度洋海岸也有丝绸贸易。锡兰，凭借其中心位置，成为中国商人会见阿拉伯商人和了解最西方国家的地方。因此，汉朝人了解非洲并且有书籍描述了红海和非洲沿岸国家的情况。公元97年，甘英，一位中国大使，从陆路到了东罗马并且把一位非洲国王所赠的礼物一犀牛角带回到洛阳。 ① It is well known that …众所周知。这是固定句型。此句可换成：As is well known, … It is well known that he works hard. = As is well known, he works hard. ② have contacts with与某人有联系 ③ find one’s way 设法到达 归纳拓展 feel one’s way摸索着走; 谨慎行事 make one’s way fight one’s way打出道路 push one’s way 挤出一条路 lose one’s way迷路 all the way by the way by way of in a way in no way in the way I hope you can find the way home.

They were traded to merchants from the Arabic countries, Egypt, Greece, Rom, India, Ceylon and China. 在以后的几百年间，索马里王国以及非洲沿海的岛屿发展成为了世界贸易中心，主要经营象牙、香料、犀牛角；贝壳、动物皮毛和糖。这些物品远销到阿拉伯国家、埃及、希腊，罗马、印度、锡兰和中国的商人手中。 ① off Keep off the grassland ! cut a piece off the loaf The ship was brown off its course. ② develop into the world’s trading centre 发展成为世界贸易中心 The Arabic contacts to the American coast led to the next meeting between black people and Chinese. In the year 751, the Chinese traveler, Du Huan, was taken prisoner① by the Arabic army. He escaped, and after a long journey wandering② through Arabic countries. 这些阿拉伯人与非洲海岸的接触为后来一位中国人和黑人的会谈准备了条件。公元751年，中国的旅行家——杜环被阿拉伯军队所俘虏。他逃跑了，在经历了阿拉伯国家的长途跋涉之后，于公元762年乘小船回到祖国。回国后，他写了《经行记》，讲述了中亚、阿拉伯以及非洲国家的情况。 ① be taken prisoner被抓: someone who is kept in a prison as a legal punishment for a crime or while they are waiting for their trial Our pilot was taken prisoner . ② wander ( 常与about /in/ through连用) The children wandered in the woods.

In the eleventh century, the Africans made several voyages to the court of the Song Dynasty. It was a major development that the Americans were reaching out to China.

Nothing similar has ever been found in East Africa. 在十一世纪，非洲人曾几次通过海路到达宋朝王宫。这是非洲人开始了解中国的一次大发展。在非洲发现的最早的亚洲文化遗产也是从这一时期开始的。一个小青铜狮子塑像已经在尚加的索马里城发现了，还没有类似的东西在东非被发现。 The contacts between China and Africa over the countries had led to the awareness of each other’s existence①, but still no accurate② maps of the countries around the Indian Ocean existed. By the beginning of the fifteenth century the time was ripe for a grand meeting③. In East Africa the coastal towns were reaching the height of④ their power. In the east, China prospered under a new dynasty. The Ming government had a large navy and the will to use it. 中国和非洲几个世纪的接触让双方知道了彼此的存在，但当时还没有精确的地图描述印度洋周围的国家。到了15世纪初，召开一次大型会议的时机已经成熟。东非沿岸城市正进入鼎盛时期。而在东方，中国在一个新的朝代的统治下也繁荣起来了。明朝政府拥有一支强大的海军并且也有发挥这支海军作用的想法。 ① the awareness of each other’s existence意识到彼此的存在 ② accurate, correct, exact辨析(inaccurate adj. 不准确的) 均含“正确的”意思。 accurate 表示“准确的”,精确的”,指“通过努力, 使事情达到正确”, 如: She gave an accurate account of the accident. 她对事故做了准确的描述。 correct 为一般用语, 指“正确的”, 如: He gave correct answers to the questions. 他对这些问题提出了正确的答案。 exact 表示“确切的”,“精确无误的”,指“与事实完全相符”, 如: His answer is quite exact. 他的回答完全正确。 ③ reach the height of power到达了繁盛时期 ④ The time was ripe for a grand meeting. 正式往来的时机成熟了。 In the years between 1405 and 1433, seven large treasure fleets① sailed westwards on voyages of trade and exploration②.

The African king sent the Ming emperor a royal present②; two giraffes. The wonderful gift and the contact with the black court so excited China’s curiosity about Africa that Zhang He sent a message③ to the king and to other African states, inviting them to send ambassadors, and open embassies④ in the new Ming capital, Beijing. The response of the African rulers was very generous; They sent the emperor zebras, giraffes, shells, elephant ivory and rhinoceros-horn medicine. In return⑤, the Ming court sent gold, spices, silk, and various other presents. The exchange of goods had a symbolic meaning⑥ far more important than the value of the goods themselves. By trading with the fleet the African kings were showing their friendship to the emperor of China. 郑和恢复了和非洲东海岸国家的联系。非洲国王送给明朝皇帝一个皇室的礼物：两只长颈鹿。这个精美的礼物和与非洲国家的接触使中国人对非洲如此好奇，以至于郑和给那个国王和别的非洲国家送信，邀请他们派大使并在明朝首都——北京开办大使馆。这些非洲国家的领导者很慷慨，他们给明朝皇帝送来了斑马、长颈鹿、贝壳、大象象牙和犀牛角药品。作为往来，明朝皇帝给他们送去了黄金、香料、丝绸和各种别的礼物。这种礼物的交换的象征意义远远重于这些物品本身的价值。通过和这支船队的贸易，非洲国王开始表示对中国皇帝的友谊。 ① renew relations重新确立关系 ② send sb. a royal present送某人贵重礼物 ③ He sent a message to…, inviting them to send….他发信给…, 邀请他们派…。 指点迷津 当表示打电话、写信、发电报告诉某人做某事时，常用-ing形式表示伴随。 send a message to sb. 送信 ④ open embassies设立使馆 ⑤ in return作为回报 ⑥ a symbolic meaning 象征意义 The fleet made several expeditions before the exploration was stopped, probably for economic reasons.
