The Faxian vehicle has surveyed more than 3,000/400 sites and has collected 3/3,000 tons of geological samples. Task 2 Circle the best words to complete the sentences below. Task 3 Answer these questions. 1. When was Kexue first put into operation? In 2014. 2. What is the purpose of designing this vessel? It’s designed to _________________________, such as sea surface and water body detection, deep-sea environment investigation, atmospheric exploration, and the conducting of onboard experiments. conduct a wide range of tasks 3. What achievements has Kexue made? Thanks to the Kexue, the IOCAS _________________ in building a world-class platform for marine research: marine landforms, seabed environments and water bodies. has taken the lead 4. What is the function of Faxian? To gather an enormous amount of environmental information and to carry out field experiments. 5. What did IOCAS conduct research on the Western Pacific Ocean System for? To research and investigate major scientific issues of the extreme marine environment. Read together Oceans are the cradle of life and cover over two-thirds of our planet. However, much of the sea is still unknown to us, especially the deep-sea waters of which we have only explored less than five percent. Lots of questions await further exploration and scientific study. With advances in marine research technology, we have been able to gradually unveil the mysteries of the sea. Deep-sea research has become an important strategic step for China to develop into a marine power. It is also an important symbol of the country’s level of technology and overall strength. China’s most sophisticated research vessel, Kexue, was first put into operation in 2014 and is a key part of the country’s oceanographic programme. As a mobile marine laboratory, it is designed to conduct a wide range of tasks, such as sea surface and water body detection, deep-sea environment investigation, atmospheric exploration, and the conducting of onboard experiments. Thanks to Kexue, the Institute of Oceanology, Chinese Academy of Sciences, has taken the lead in building a world-class platform for marine research. One example is the high-precision detection system that has been set up to investigate marine landforms, seabed environments, and water bodies. The IOCAS has also conducted comprehensive investigation and research on the Western Pacific Ocean System, targeting major scientific issues of the extreme marine environment, like cold springs and seamounts. A remotely-operated vehicle, Faxian, enables scientists to gather an enormous amount of environmental information and to carry out field experiments. To date, over 3,000 biological samples have been collected, nearly 3 tons of geological samples have been obtained, and more than 400 sites have been surveyed. As reported by the Nature journal, China is now fully capable of carrying out deep-sea research, and its scientific deep-sea explorations have made many significant discoveries. Today, marine science is more important than ever. Continuing in the tradition of Zheng He’s voyages over 600 years ago, China’s scientific pioneers are writing a new chapter in marine exploration. After you watch Discuss the questions. 1. Human beings have explored less than 5% of the world’s oceans. Why do you think we have explored so little of the oceans so far? Probably because we have lacked the technology to do much research of the deep ocean. 2. What do you think is the difference between Zheng He’s voyage 600 years ago and China’s sea exploration today? Zheng He’s mission was to develop relations with other countries. Today, China’s sea exploration has a very different purpose: to explore and research the deep ocean which no humans have visited before. 3. Why is marine science important for China today? Deep-sea research has become an important strategic step for China to develop into a marine power. It is also an important symbol of the country’s level of technology and overall strength. Why is marine science important for China today? What should we pay attention to during the research? Write down your opinions.

Deep sea research has become an important strategic step for china to develop into a marine power. IT is also an important symbol of the country's level of technology and overall strength. China's most sophisticated research vessel, kosher was first put into Operation in two thousand and fourteen, and is a key part of the country's oceanographic program. As a mobile marine laboratory, IT is designed to conduct a wide range of tasks such as sea surface and water body detection, deep sea environment investigation, atmospheric exploration and the conducting of on board experiment. Thanks to kosher, the institute of ocean ology chinese academy of sciences has taken the lead in building a world class platform from marine research. One example is the high precision detection system that has been set up to investigate marine landforms sea bed environments and water bodies. The IOCAS has also conducted comprehensive investigation and research on the western pacific ocean system, targeting major scientific issues of the extreme marine environment like cold springs, and see mounts. A remotely Operated vehicle fashion enable scientists to gather an enormous amount of environmental information and to Carry out field experiments. To date, over three thousand biological samples have been collected, nearly three tons of geological saplings have been obtained, and more than four hundred sites have been surveyed. As reported by the nature journal, china is now fully capable of Carrying out deep sea research, and its scientific deep sea explorations have made many significant discoveries. Today, marine science is more important than ever. continuing. In the tradition of john huz voyage over six hundred years ago, china's scientific pioneers are writing a new chapter in marine exploration.
