选修7 Unit 3 Under the seaⅠ.阅读理解Saving our oceansYour MissionTeach oceanographers(海洋学者)with different specialties about other ocean specialties and thus create a better understanding of the ocean as a complete, diverse system.BriefingYou ve been invited to lead the International Oceanographic Conference in Oslo, Norway. Over one hundred of your fellow oceanographers will attend it. The problem is that,with so many different specialties in the field—from geological to biological oceanography—the oceanographers at the conference are finding it difficult to understand what their colleagues are studying,let alone to grasp the ocean as an entire,diverse system!Your job will be to give the opening speech at the conference outlining the general kinds of oceanography in a way that each type of oceanographers will understand. Then, you will assign different oceanographers to different projects and explain to them how best to work together.Family-x fileYounger Xpeditioners:Pick one project,and learn more about it through its photo gallery. Then, create a poster based on the animals and terrain(地形). Make sure to label each animal that you draw. Show your poster to your family and describe to them what you have drawn.Older Xpeditioners:Learn more about each of the projects:Where (in the ocean) would oceanographers go to study them? What animals might oceanographers study in the project? Which types of oceanographers would you assign for each project and how would they work together?Finally,think about the ways in which the different general kinds of oceanography might relate. Why is it important to look at the ocean as an entire system, rather than as distinct parts? How might looking at each separate part and the ocean as a whole impact conservation efforts?
