Unit 5 Into the unknown Developing ideas 新标准《英语》高中选择性必修第四册 Activity 1 Look at the picture and answer the questions. Do further research if necessary. What different zones are there in the ocean? Which parts of the ocean do you think have been explored? What do you know about the deepest part of the ocean? The different zones in the ocean are Sunlight Zone, Twilight Zone, Midnight Zone and Abyssal Zone. 2 Activity 2 Read the passage and find out what has been discovered in the ocean depths. Shipwrecks such as that of the Esmeralda, ruins of ancient cities like Neápolis, extraordinary deep-sea creatures such as bone-white coral and the barreleye, and the substance known as “fire ice” have been discovered in the ocean depths. 3 Activity 3 Think about the structure of the passage and complete the diagram. deep sea Archaeological shallow waters vast depths the ruins of Neápolis Biological the planet’s fish the capacity for life on our planet bone-white coral the barreleye life to be found even around the deep-sea volcanic openings the sea bed deep-sea drilling “fire ice” China’s underwater vessels Think & Share Why do you think the author uses statistics in the passage? What other examples of ocean exploration do you know of? Share one with the class. What do you think drives the exploration of the oceans? What common message do the two reading passages in this unit convey? How do they each build upon this idea? 1. The use of statistics makes the passage more convincing. 4. Both passages convey the message that humans have the desire and means to explore the unknown. The first passage does this by looking at our fascination with history’s greatest mysteries, while the second passage looks at pioneering exploration of Earth’s oceans. Activity 4 Work in groups. Give a talk about the influences of ocean exploration on your daily life. Look at the diagram below and brainstorm examples of how ocean exploration affects your daily life. Organise your talk by completing the diagram with your examples. Give your talk to the class. Now think about how well you contributed to the group work and what you could do to improve. 8 Activity 5 1. Why is the 30th parallel north mysterious? 2. What are some unusual explanations for it? 3. What are some possible scientific explanations? Read the magazine article and answer the questions. The 30th parallel north is mysterious because it is where numerous sites of ancient civilisations and impressive natural features lie. Some believe that the 30th parallel north is a line of great natural energy, with frequent earthquakes and volcanic eruptions, and others even claim that its amazing natural features were caused by supernatural powers. Possible scientific explanations for the 30th parallel north include the generally warm and damp climate that made it a good place for civilisations to develop, and the fact that it is where major tectonic plates meet. Activity 6 What is the unexplained phenomenon? Why is it mysterious? What non-scientific explanations are there? How do scientists explain it? Plan an article about an unexplained phenomenon. Do further research if necessary. Now write your article. Activity 7 Work in pairs. Make improvements to each other's articles and share them with the class. The Bermuda Triangle Far below the surface of the North Atlantic Ocean, in a roughly triangular area known as the Bermuda Triangle, lie more than 50 shipwrecks and 20 plane wrecks. What makes these wrecks so mysterious is that the cause of their fate remains largely unknown – ships were abandoned without apparent reason, distress signals were never sent and aircraft were lost without trace. Some believe that supernatural forces are responsible, while others put the accidents and disappearances down to coincidence. Scientific theories, meanwhile, include pilot error when trying to navigate the area, and huge “rogue waves” caused by terrible storms. Although many ships and planes cross the Bermuda Triangle without incident, the stories behind those doomed vessels’ fates continue to capture people’s imaginations.
