The other reason is less obvious. The entire ocean gets its oxygen from the surfaceeither from the atmosphere, or from photosynthesizing algae floating at the top of the sea. 27 Global warming is expected to reduce the mixing of the ocean by making surface seawater lighter. Thats because in a warmer world we can expect more rainfall and more melting (融化) of glaciers, icebergs, and ice sheets. 28 The extra heat from the warming atmosphere will also make surface water expand and thus make it lighter still. 29 Instead, more of the oxygen will remain near the surface, where it will be used up by oxygenbreathing organisms.A lowoxygen ocean may become an inescapable feature of our planet. A team of Danish researchers wondered how long oxygen levels would drop if we could somehow reduce our carbon dioxide emissions to zero by 2100. They determined that over the next few thousand years oxygen levels would continue to fall, until they declined by 30 percent. The oxygen would slowly return to the oceans, but even 100,000 years from now they will not have fully recovered. 30 A. Its not known why the oxygen level of oceans has reduced.B. Scientists point to two reasons to expect a drop in ocean oxygen.C. Fresh waters inpouring will make the water at the oceans surface lighter.D. The oxygen then spreads to the deep ocean as the surface water slowly sinks.E. Global warming has caused the reduction of the oxygen content of oceans worldwide.F. The light surface water will be less likely to sink so the deep ocean will get less oxygen.G. If they are right, we have every reason to worry about the major effect it has on sea life.五、书面表达【2018-2019学年河南省郑州市第一中学高二上学期入学测试英语试题】假如你是李华，你的英国朋友Tom来信询问雾霾严重时你校如何保证正常上课。请你根据以下要点给Tom回信：1. 政府在为学校安装新风系统；2. 家长在为学校捐赠空气净化器；3. 学校减少学生不必要的户外活动。参考词汇：雾霾haze；新风系统fresh air system；空气净化器air purifier注意：1. 词数100 左右；2. 可以适当增加细节，以使行文连贯。_寒假训练09 Unit 4 Global warming一、单项选择【答案】1-5 DBBAB 6-10 BBCDB【解析】1. 考查交际用语。句意：很抱歉我迟到了。路上堵车了。没关系。你来了就好，进来坐吧。Never mind“没关系，不要紧”，符合语境。2. 考查固定句型。句意：我现在遇到大麻烦了。你可以相信我们所有的人都将支持你。depend on it that.“相信/指望”，为固定句型，it作形式宾语，真正的宾语是that引导的从句的内容。3. 考查名词辨析。句意：当你决定建立一个家庭的时候，你就对他们有了一份承诺/委托，你不能不理会爱你的人。commitment“委托，承诺”；contribution“贡献”；devotion“奉献”；effort“努力”。句中的turn ones back on意为“不理睬”。4. 考查名词。句意：许多年来，科学家们一直担心空气污染对地球的自然环境带来的影响。effect“影响”；result“结果”；account“叙述，账目”；cause“原因，事业”。根据句意及on可知此处为effect。5. 考查时态。句意：那是件很漂亮的毛衣。我以前从来没见过这样的。你真的这么认为吗？我奶奶给我织的。根据语境可知make是过去的动作，所以用一般过去时。A.指现在经常性或习惯性的动作；C.现在完成时用于强调过去的动作对现在造成的影响或结果；D.过去完成时表达在过去的时间或动作之前完成的事。6. 考查介词短语。句意：你的台湾之旅怎么样？从总体上说，我很喜欢这次旅行，尽管有时天气有点热。in addition“另外”；on the whole“从整体上说”；in other words“换句话说”；on the other hand“另一方面”。7. 考查形容词辨析。句意：约翰上周被开除是因为他对待工作的态度太随便。informal“非正式的”；tough“强硬的，艰苦的”；violent“暴力的”。8. 考查固定句型。not.until.句型变为强调结构时，不用when引导，要用that 引导，that后的从句用陈述语序。9. 考查动词短语。句意：你支持过低碳生活的想法吗？听起来牵强，但它是一种趋势。subscribe to“支持”；correspond to“与相对应”；apply to“适用于”；cater to“迎合”。10. 考查主谓一致。第一空填quantity，因为a number of修饰可数名词，第二空填has，因为a large quantity of desert是不可数名词，谓语保持一致，句意是：由于森林的毁坏，大量的沙漠覆盖了土地。选B。二、单句改错【答案】11. has改为have12. Comparing改为Compared13. speak 改为 speaking14. in改为on15. agree改为agreement16. will 改为 would 17. destroyed前加 being18. subscribed 后加 to 19. resulted 改为resulting20. 去掉a 【解析】11. 考查主谓一致。“quantities of”是复数，谓语动词则与复数保持一致。12. 考查非谓语动词。our small flat 被与Bills house比较，表示被动用Compared。13. 考查动名词用法。When it comes to接n.或动名词，意为“当谈到”。14. 考查固定短语。on the other hand “在另一方面”。15. 考查名词。句意：两党之间正在友好的氛围中交谈。希望他们能达成协议。16.考查虚拟语气。该题为if虚拟条件句的省略倒装，仍是对现在的虚拟，从句用一般过去时（were），主句用would/could/might/should+动词原形，故此处需将will改为would。17. 考查with复合结构。句意：随着更多森林被毁，每年有许多良田被冲走。forest 与destroy之间是动宾关系，用被动形式。18. 考查固定短语。subscribe to 意为“同意，订阅”。19. 考查非谓语动词。resulting在句中作结果状语，与主语是主动关系。20.考查固定短语。on behalf of 意为“代表”。三、完成句子【答案】21. It was she who /that22. results in a wide range of 23. even if it rains24. How does it come about25. on behalf of him四、七选五【语篇解析】本文是说明文。文章简要介绍了海水中氧气含量降低的主要原因及其可能对海洋生物带来的长期的影响。【答案】26-30 BDCFG【解析】26. 主旨概括句。从文章篇章结构分析，本空为段落主旨句。本段介绍了全球变暖使海洋含氧量降低的原因，并且 “One” “The other reason”与B项中的 “two reasons”相呼应，故选B。27. 细节支撑句。根据段落主旨和空前的 “The entire ocean gets its oxygen from the surface. at the top of the sea”可知，此处是通过说明海洋中氧气的来源与循环来解释海洋含氧量下降的原因的，故D项“然后，随着表层海水的慢慢下沉，氧气扩散至海洋深处”符合语境。28.细节支撑句。根据空前的内容和常识可知，雨水和冰川、冰山及冰原融水都属于淡水，海洋中的水是咸水，而淡水的密度比咸水的小，因此淡水的注入会使海洋表面的水变得更轻。故C项符合语境。C项中的 “make the water. lighter”与下文中的 “make it lighter”的对应关系亦是提示。29.细节支撑句。根据空前的 “The extra heat from the warming atmosphere will.”和空后的 “Instead, more of the oxygen will remain.”可知，F项与空前的句子的句式相同，且与空后的句子的内容存在语意上的转折关系，故F项符合语境。30.细节支撑句。G 项中的 “they”与上文中的 “A team of Danish researchers”相呼应，且上文讲到即使我们把二氧化碳的排放降低到零，海洋含氧量也需要很长时间才能恢复，其对海洋生物造成的影响将是长期的，故G项“如果他们是对的，那么我们完全有理由对它对海洋生物的重大影响感到担忧”符合语境。五、书面表达【答案】Dear Tom,I am writing in response to your concern about ways of ensuring normal teaching activities in our school in case of heavy haze. Thanks for your concern anyway.Several parties are involved in fighting haze. First of all, the government has funded the installation of the fresh air system. Second, enthusiastic parents have donated enough air purifiers which help improve the air quality. Whats more, our school limits the time for outdoor activities, exposing us to as little polluted air as possible.Thanks to the joint efforts, we are now enjoying our school life.Yours,Li Hua
