Then we can go to see the seahorses whose number declined greatly for the past decade. However, most people do not know much about seahorses at all. I think we need to raise awareness about seahorses and marine conservation in China. The last spot will be The Chinese Pavilion, which displays the aquatic organisms and bio-system in the Yangtze River and some national endangered rare aquatic creatures, like Chinese alligator and Chinese sturgeon.PartⅠPractice1.China is a country with vast oceans. We are bound to explore the sea and accelerate the construction of ocean power.2.We are determined to take measures to prevent the ocean ecological environment from becoming worse. We are determined to improve the environment significantly and ensure that the masses can consume green and safe sea products as well as enjoy the blue sky and clean seashores.2.Express your opinions on sea exploration学案设计学习目标:1.To figure out the organisation and language feature of an argumentative essay.2.To learn to express their opinion on sea exploration.3.To write an argumentative essay on sea exploration.4.To develop a proper attitude on sea exploration.Part ⅠWhile-readingActivity1Reading for text type.What is the type of the text?A.Exposition.B.Narration.C.Argumentation.D.Description.Activity2Reading for the structure.What are the three parts in an argumentative essay?_________________________________________________________________ Activity3Reading for detailed information.Read the two texts on Page 32 and find the arguments,evidence and restatement in them._________________________________________________________________ Activity4Reading charts.Look at the two charts below and decide which one supports which text._________________________________________________________________Decline in oil spillsGlobal trends in the state of world marine fish stocksPartⅠDiscussionActivity1In groups, discuss the following questions.1.What is your opinion about sea exploration?_________________________________________________________________2.Are there any other aspects of sea exploration not mentioned that you think are important?_________________________________________________________________ Activity2Writing.Write an argumentative essay on sea exploration.The following questions may help you.·What is the purpose of sea exploration?·How does sea exploration help us to protect the sea?·How does sea exploration cause damage to the sea?·Is there a good balance between protection and exploitation?Part ⅠEvaluating and polishing the draftActivity1Use the PEEL method to help structure your argument.Point What point do you want to make?Evidence What facts and examples can you find to support your point?

We need to explore the ocean so that we can better understand issues such as acidification which leads sea water to become more acidic, and how to deal with such problems.Activity2We should explore the ocean, first and foremost, because we do not know what we do not know. We thought we knew much about the ocean, but we were wrong. There could be life forms in the ocean, for example, that fit none of the categories we have for life. We already know many things about the ocean, but we need tolearn more. A good example is ocean acidification, which is causing coral reefs to die. We know that using less fossil fuel would cause the process to slow down. We need more research to come up with plans and solutions.To do the research, we have to enter an extreme environment not friendly to humans. This requires the development of new technologies that can also benefit us in other areas.All in all, there are many good reasons to explore the ocean. If we care about science, about protecting our oceans, and about developing new technologies, we need to do all we can to support ocean exploration.PartⅠEvaluating and polishing the draftActivity1略Activity2略Part ⅠHomeworkTopic: Reducing pollutionToday our oceans are under threat because of pollution. What can we do to stop the crisis?First, we can stop using single-use plastic products such as plastic shopping bags. These products can take 450 to 1,000 years to biodegrade. Our oceans have become one giant rubbish bin of plastic waste, threatening sea life. We can keep this problem from growing by recycling bottles and using our own shopping bags at the market.Second, we can make stronger laws so that farmers will not use chemicals harmful to the environment and factories will not be able to dump their waste into our waters. Since all rivers in the end empty into the sea, chemicals from a farm or factory will eventually make their way to the ocean, killing sea life and destroying the ocean’s delicate balance.Third, we can reduce our carbon footprint by using less fossil fuel. While this may not look like an issue that has much to do with the ocean,rising temperaturedue to climate change has started to cause our coral reefs to die. As these reefs provide a habitat for thousands of animal species, these species will decline. Scientists predict that this will result in mass hunger, because so many people depend on sea life for food.The future of our oceans is in our hands. If we act now, they can still be saved, and they will still be a resource for future generations.。
