Step Ⅱ 应用实践
活动三：分析与判断
Discussion.
Ask students to work in groups of four and discuss the following questions.
·What are some advantages of paramotors over traditional forms of water rescue What are some disadvantages
·As a business, how might the Para-Life rescue service make money Is it right to charge victims for rescue If so, how much should they be charged What if they cannot pay
·What other interesting or new kinds of rescue are there How do they work
Suggested answers:
·The main advantage is the ability to spot the person who is in trouble and get there quickly. The main disadvantage is that the paramotor cannot land and pick the person up.
·It could make money through a contract with the government. While it does not seem right to charge the victims money, in fact ambulance services, doctors, nurses, and hospitals charge victims money all the time. If people are charged money, it should be based on the time and expense required to rescue them, but that amount is hard to determine. As the victim would be billed after the rescue, if the victim cannot pay it will be just like any other bill the victim might have,
·One kind of rescue involves dogs that can sniff out people trapped in buildings after an earthquake. The dog just wanders over the ruined building sniffing the ground. If it smells a person, it makes a sign or begins to bark. Rescuers then know where to dig. As a person can survive for as long as three days without water, so long as the person can breathe and is not too badly injured there is still a good chance of rescue in this situation.
【设计意图】在观看视频后，让学生讨论滑翔伞搜救相比于传统海上救援的优缺点、发表自己对滑翔伞救援队是否应收费的看法和态度、提出新类型的救援方式等，有助于培养学生多元思维和利用本课所学的词汇在新的语境中表达自己的观点，促进知识的内化，加深对主题意义的理解。
