More exploration means more pollution.The Deepwater Horizon spilled over 200 million gallons of oil into the sea in 2010.Plastic pollution is also bad，killing many birds and fish，and has even been found in our tap water. Mining for resources is very damaging，especially in the Arctic.①Because of climate change，there is less ice now，which means we can look for more fossil fuels further north．But if we burn these，the ice will melt more and this negative cycle will continue.Climate change is warning us that something is very wrong. Overfishing is another problem.Whales and dolphins are also hunted for their meat or for so-called research.Although this was banned in 1982，some countries are still “murdering” these intelligent creatures without mercy. The sea is home to life，not human beings' possessions.It is huge，but it is more sensitive than we think.If we do not protect it，future generations will not forgive us. Text 2 To truly understand our planet，we must explore the oceans which cover most of it.Opponents may be concerned，but sea exploration is important for our future.For example，scientific research ships can help address important issues such as climate change. ②We need to understand what is happening to our planet so that we can take action. Therefore，more research is necessary. Understanding more about the sea will also help us manage its resources better.Logging new species will improve our understanding of life on the earth.It may help us discover new medicines，as well as new sources of food and energy.Accessing the deep ocean may also help us to predict events such as earthquakes. The population of the world is growing and we need new resources for future development.There are probably vast amounts of resources under the sea and ice，not just oil and gas but also valuable minerals. Of course，there are still environmental risks.However，these should be balanced with economic needs.Hopefully，as technology improves，we may have more options for managing this balance. ◎………………………………………………………………………………… 学语言 Ⅰ.精彩表达 1．采用比喻夸张等手法，如 “murdering” these intelligent creatures without mercy中使用murdering一词把捕猎鲸鱼和海豚的行为比喻为“谋杀”。 2．利用举例使表达更清楚，比如For example，scientific research ships can help address important issues such as climate change.能使读者清楚海洋开发的重要性。 Ⅱ.句法结构 ①本句为主从复合句。句子主干为there is less ice now，which引导非限制性定语从句，从句中的谓语动词means后跟宾语从句，省略了that。 学生用书第88页 ②本句为主从复合句。句子主干为We need to understand，其后跟what引导的宾语从句，以及so that引导的目的状语从句。 知结构 1．框架结构 两篇课文均采用“总—分—总”结构。 (1)开篇：提出观点。 (2)主体：从几个不同方面论述支撑观点。 (3)结尾：总结照应首段主题。 2．启发写作 (1)本单元的写作项目属于新课标中议论体类别中的“辩论性议论文”。它是对某个议论对象提出见解或主张并说明理由，使读者信服的文章。作者通过摆事实、讲道理、辨是非来确定其观点的正误，支持或否定某种主张，从而达到让读者信服或接受其观点或看法的目的。 (2)议论文通常采用总分总三段模式，即开篇点题，中间从不同角度阐述，末段总结照应。 [情境任务写作] 假设你是新华中学的李华，最近，你们班同学就是否应该进行海洋探索展开了热烈的讨论。有人赞成，有人反对，请你就此事用英语写一篇发言稿，表达你的个人看法。 注意：1.写作词数应为80左右； 2．可适当增加细节，以使行文连贯。 [仿写程序步骤] 1．一仿结构布局合理 首段：引入主题，即海洋探索的讨论。 主体：介绍双方观点。 尾段：简述自己的观点。 2．二仿语言规范美观 根据要求完成下列句子。 学生用书第89页(1)我们班一直在讨论人们是否应该去探索海洋。 Our class has been discussing whether people should explore the sea or not． (2)有些人强烈反对，而另一些人则赞成。我对此印象深刻。 Some are strongly against it while others approve of it.I was strongly impressed by this. (3)正如各种媒体所报道的那样，海洋勘探造成了许多问题，如污染、过度捕捞等。 As reported in various media，many problems have been caused by sea exploration，such as pollution，overfishing，and so on. (4)海底蕴藏着丰富的矿藏，等待着我们去开采。 Under the sea are abundant minerals，waiting for us to mine． (5)在探索海洋的同时，我们必须保持海洋探索和海洋保护之间的平衡，这样环境才能避免被破坏。 While we explore the sea，we must keep the balance between sea exploration and sea conservation so that the environment can avoid being damaged. 3．三仿句式高级表达 (6)把(2)中的句子用what主语从句改写。 What impresses me most is that some are strongly against it while others approve of it. (7)将(5)中的while从句改写成省略结构。 While exploring the sea，we must keep the balance between sea exploration and sea conservation so that the environment can avoid being damaged. 4．四仿教材连句成篇(适当添加过渡语) 参考范文 Lately，our class has been discussing whether people should explore the sea or not.What impresses me most is that some are strongly against it while others approve of it. For one thing，as reported in various media，many problems have been caused by sea exploration，such as pollution，overfishing，and so on.For another，under the sea are abundant minerals，waiting for us to mine. Personally，while exploring the sea，we must keep the balance between sea exploration and sea conservation so that the environment can avoid being damaged.
