(课件网) Unit 3 Video Time 年 级:高三 学 科:高中英语(人教版 选必四) Learning Objectives At the end of this class, you will be able to 1. understand some words and phrases related to marine research, like vessel, samples, atmospheric, conduct tasks and so on; 2. know more about China’s most sophisticated vessel Kexue and the research work on it; 3. realize the importance of marine research. Thinking Why do people explore the ocean Possible answer: Ocean exploration is about making discoveries, searching for things that are unusual and unexpected. Through ocean exploration, we collect data and information needed to address both current and emerging science and management needs. We can more effectively manage, conserve, regulate, and use ocean resources. Deep into the Sea The video is about Kexue, China’s most sophisticated research vessel, which is designed to conduct a wide range of tasks. Based on Kexue, China has taken the lead in building a world-class platform for marine research. Introduction of the video It is the most sophisticated research vessel. Its tasks include: water body detection deep-sea environment investigation atmospheric exploration conducting onboard experiments collecting geological samples. 1. Do you know the vessel Kexue 2. What do you know about the vessel Kexue Look at the pictures from the video. What do you think these people are doing Before you watch B.
