1、高考资源网（） 您身边的高考专家单元主题语境人与自然之人与环境、人与动植物(2019高考北京卷)话题：气候变暖与海洋颜色变化词数：274难度：By the end of the century，if not sooner，the worlds oceans will be bluer and greener thanks to a warming climate，according to a new study.At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton.B

2、ecause of the way light reflects off the organisms，these phytoplankton create colourful patterns at the ocean surface.Ocean colour varies from green to blue，depending on the type and concentration of phytoplankton.Climate change will fuel the growth of phytoplankton in some areas，while reducing it i

3、n other spots，leading to changes in the oceans appearance.Phytoplankton live at the ocean surface，where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen.When these organisms die，they bury carbon in the deep ocean，an important process that helps to regulate the global climate.Bu

4、t phytoplankton are vulnerable to the oceans warming trend.Warming changes key characteristics of the ocean and can affect phytoplankton growth，since they need not only sunlight and carbon dioxide to grow，but also nutrients.Stephanie Dutkiewicz，a scientist in MITs Center for Global Change Science，bu

5、ilt a climate model that projects changes to the oceans throughout the century.In a world that warms up by 3 ，it found that multiple changes to the colour of the oceans would occur.The model projects that currently blue areas with little phytoplankton could become even bluer.But in some waters，such

6、as those of the Arctic，a warming will make conditions riper for phytoplankton，and these areas will turn greener.“Not only are the quantities of phytoplankton in the ocean changing，” she said，“but the type of phytoplankton is changing.”And why does that matter？Phytoplankton are the base of the food w

7、eb.If certain kinds begin to disappear from the ocean，Dutkiewicz said，“it will change the type of fish that will be able to survive.”Those kinds of changes could affect the food chain.Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable，bu

8、t they could mean significant changes.“Itll be a while before we can statistically show that the changes are happening because of climate change，”Dutkiewicz said，“but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”语篇解读本文是一篇说明文。调

9、查表明，由于气候变暖，全球的海洋将会变得更蓝、更绿。本语篇话题新颖，知识性强，旨在引导考生从生态文明的视角思考环境保护的意义和价值，共建绿色家园。42What are the first two paragraphs mainly about?AThe various patterns at the ocean surface.BThe cause of the changes in ocean colour.CThe way light reflects off marine organisms.DThe efforts to fuel the growth of phytoplankton

10、.解析：段落大意题。文章第一段点题：由于气候变暖，全球的海洋将会变得更蓝、更绿。第二段介绍由于光从生物体反射的方式，这些浮游植物在海洋表面形成了五颜六色的图案；气候变化又使得这些浮游植物在某些区域加速生长而在其他地方有所减少，导致海洋表面的颜色变化。由此可知前两段讲了海洋颜色变化的原因，故B项正确。答案：B43What does the underlined word “vulnerable” in paragraph 3 probably mean?ASensitive.BBeneficial.CSignificant.DUnnoticeable.解析：词义猜测题。画线词后一句提到，气候变暖

11、改变了海洋的主要特点并能影响浮游植物的生长，因为它们要生长不仅仅需要阳光和二氧化碳，也需要养分。由此可知，这些浮游植物对海洋变暖很敏感，故A项正确。答案：A44What can we learn from the passage?APhytoplankton play a declining role in the marine ecosystem.BDutkiewiczs model aims to project phytoplankton changes.CPhytoplankton have been used to control global climate.DOceans wit

12、h more phytoplankton may appear greener.解析：推理判断题。由倒数第二段可知，这些浮游植物是海洋食物链的基础，如果某些种类的浮游植物消失了，会影响能存活的鱼的类型，从而影响海洋食物链，所以A项“浮游植物在海洋生态中所起的作用越来越小”是不对的；Dutkiewicz的模型不是用来推断浮游植物的变化的，而是推断海洋的变化的，排除B项；浮游植物不是用来控制全球气候的，排除C项。由第四段中的“But in some waters，such as those of the Arctic，a warming will make conditions riper for

13、 phytoplankton，and these areas will turn greener.”可知，浮游植物多的区域海水会变得更绿，故D项正确。答案：D45What is the main purpose of the passage?ATo assess the consequences of ocean colour changes.BTo analyse the composition of the ocean food chain.CTo explain the effects of climate change on oceans.DTo introduce a new met

14、hod to study phytoplankton.解析：主旨大意题。文章主要论述了随着气候变暖，全球的海洋将会变得更蓝、更绿，即气候变化对海洋有影响，故C项正确。答案：C一、语言能力熟词生义/ 词类活用1fuel vt.促进；加强2key adj.主要的3matter vi.重要，要紧4while n一段时间二、思维品质1阅读技巧词义猜测题的解题技巧常用的词义猜测技巧有：1.根据定义或上下文解释进行猜测；2.根据同位关系进行猜测；3.根据构词法(前缀、后缀、复合、派生等)进行猜测；4.根据转折或对比关系进行猜测。如第43题，由转折连词but及下一句可知，气候变暖改变了海洋的主要特征，影响了

15、浮游生物的生长，因为它们不仅需要阳光和二氧化碳才能生长，而且需要养分，可知本句主要是说浮游生物对气候的变化很敏感。2分析长难句并翻译句子Climate change will fuel the growth of phytoplankton in some areas，while reducing it in other spots，leading to changes in the oceans appearance.分析此句中while表对比，意为“然而，不过”；现在分词短语leading to changes in the oceans appearance在句中作结果状语。翻译气候变化

16、将在某些地区促进浮游植物的生长，而在其他地区则会减少浮游植物的生长，从而导致海洋外观的变化。三、文化素养思考：通过阅读这篇文章，你对海洋及海洋生物有何认识？海洋是生命的摇篮，在海里生活着成千上万的海洋生物。它们不仅是维护地球生态系统的重要组成部分，而且为人们提供了大量的食物。随着全球人口的激增，陆地空间已经越来越少，因此对于海洋的探索和开发就显得尤为重要。授课提示：对应学生用书第209页NO.1单词在语境中应用，在拓展中记多01核心单词先识记请根据汉语提示完成下列词块1abandon the match 放弃比赛2urge him to stay劝他留下3flee to Britain逃到英国
