All of them represent attempts over the centuries to explore Earth’s furthest corners. Among these is the Esmeralda, the earliest wreck from the age of the European exploration of Asia. Today, some 500 years after the Esmeralda set sail, there is little— if any—land on our planet left unexplored. We have more detailed maps of the Moon，and even of Venus2 and Mars，than we do of Earth’s own sea bed. Given our limited knowlede，it is perhaps no surprise that exploration of the oceans continues to lead to discoveries in various scientific fields. As with the discovery of the Esmeralda ，many archaeological finds are made in shallow waters near the coast. These may sometimes include whole cities buried beneath3 the waves. One such find is the ancient Roman city of Neápolis, discovered off the coast of Tunisia. Believed to have been buried underwater by a tsunami in the fourth century AD，the ruins of Neápolis are almost 2，000 years old. The remaining streets and buildings offer a window into a fascinating period in our history. However，we are only beginning to overcome the challenges of pressure, darkness and extreme cold at vast depths. Fragments4 of the past lying deep beneath the oceans are still waiting to be discovered. … Being a tough environment of complete darkness, enormous pressure and intense5 cold, the ocean depths have long been beyond the reach of human exploration. However，through closer international scientific, economic and cultural cooperation, we are all becoming part of a global mission to open up our planet’s final frontier6. Humankind is entering a new age of oceanic discovery, and the world beneath the waves may one day be almost as familiar to us as the land we walk upon today.

In 1371，Zheng He was born in what is now Yunnan Province to Muslim parents，who named him Ma Sanbao.When he was 11 years old，he was castrated and made to serve as a eunuch(宦官) in the imperial household.Ma befriended a prince who later became the Yong Le Emperor，one of the Ming Dynasty’s most distinguished.Brave，strong，intelligent and totally loyal, Ma won the trust of the prince who gave him a new name.Yong Le was an ambitious emperor who believed that China’s greatness would be increased with an “open­door” policy regarding international trade and diplomacy.In 1405，he ordered Chinese ships to sail to the Indian Ocean，and put Zheng He in charge of the voyage.Zheng went on to lead seven expeditions in 28 years，visiting more than 40 countries. Zheng’s fleet had more than 300 ships and 30，000 sailors.The largest vessels，133­meter­long “treasure ships”， had up to nine masts and could carry a thousand people.Along with a Han and Muslim crew，Zheng opened up trade routes in Africa，India，and Southeast Asia.The voyages helped expand foreign interest in Chinese goods such as silk and china.In addition，Zheng He brought foreign items back to China，including the first giraffe ever seen there.At the same time，the fleet’s obvious strength meant that the Emperor of China commanded respect and inspired fear all over Asia. Though Zheng He died in 1433 and was probably buried at sea，a grave and small monument to him still exist in Jiangsu Province.Three years after Zheng He’s death，a new emperor banned the construction of oceangoing ships，and China’s brief era of naval expansion was over.Chinese policy turned inward，leaving the seas clear for the rising nations of Europe.Opinions vary on why this happened.Records of Zheng He’s incredible voyages were burned.Not until the early 20th century did another fleet of comparable size take to the seas. 【语篇解读】　本文为记叙文，讲述了中国明朝郑和于公元1405年率领庞大的船队远航西洋的故事。 1．Why did Zheng He sail to the ocean? A．Zheng He befriended the Yong Le Emperor and won his trust. B．The emperor tried to increase China’s greatness by an “open­door” policy. C．The voyages helped expand foreign interest in Chinese goods. D．Zheng He wanted to promote culture and religious visits with foreign countries. 解析：选B　细节理解题。根据第二段倒数第三句可知，永乐皇帝相信通过国际贸易及外交上的“门户开放”政策，中国会在世界上享有更高的声望。C项是远航的结果，不是原因，故选B项。 2．What’s the significance of Zheng He’s seven voyages? A．They established China as the leading power from then on. B．They spread diplomacy，established trade routes and returned with treasure and foreign items never seen before in China. C．They provided pathways for religious communication between Han and Muslim crew. D．They speeded up the process of imperial reform of Ming Dynasty. 解析：选D　推理判断题。根据最后一段可知，郑和死后，明朝停止了远洋航行，中国的政策为何会发生这样的转变，一直众说纷纭，文章也没有进一步讲明，故选D项。 $
