At the heart of the phenomenon lie tiny marine microorganisms
2、(海洋微生物) called phytoplankton. Because 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 phytoplankto
3、n in some areas, while reducing it in 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 th
4、at helps to regulate the global climate. But 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 scien
5、tist in MITs Center for Global Change Science, built 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 phytoplankt
6、on could become even bluer. But in some waters, such 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.(1)What are
7、the first two paragraphs mainly about? A.The various patterns at the ocean surface.B.The cause of the changes in ocean colour.C.The way light reflects off marine organisms.D.The efforts to fuel the growth of phytoplankton.(2)What does the underlined word vulnerable in Paragraph 3 probably mean? A.Se
8、nsitiveB.BeneficialC.SignificantD.Unnoticeable(3)What can we learn from the passage? A.Phytoplankton play a declining role in the marine ecosystem.B.Dutkiewiczs model aims to project phytoplankton changesC.Phytoplankton have been used to control global climateD.Oceans with more phytoplankton may app
9、ear greener.(4)What is the main purpose of the passage? A.To assess the consequences of ocean colour changesB.To analyse the composition of the ocean food chainC.To explain the effects of climate change on oceansD.To introduce a new method to study phytoplankton【答案】 (1)B(2)A(3)D(4)C 【解析】【分析】本文是一篇说明文
10、,一项最新研究表明,由于气候变暖,世界海洋将会变得更蓝、更绿。这一现象是因为一种叫做浮游植物的微小海洋微生物,因为光线反射的作用,它们在海洋表面形成了五颜六色的图案。但是浮游植物很容易受到海洋变暖趋势的影响,气候变暖会改变海洋的主要特征,并影响浮游植物的生长。 (1)段落大意题。第一段“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.”可知,到本世纪末,一项新的研究
11、表明,由于气候变暖,如果不尽快的话,世界上的海洋将会变得更蓝、更绿。再根据第二段中的“At the heart phenomenon lie tiny marine microorganisms called phytoplankton. Becaust of the way light reflects off the organisms ,these phytoplanktons create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the t
12、ype and concentration”可知,这种现象的核心是一种叫做浮游植物的微小海洋微生物,在光线的作用下在海洋表面形成了五颜六色的图案。海洋的颜色从绿色到蓝色不等,这取决于海洋的类型和浮游植物浓度。由此可推断出这两段主要叙述了海洋生物是海洋颜色变化的原因。故选B。 (2)词义猜测题。根据第三段中的“Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunshine and carbon dioxide to gro
13、w, but also nutrients.”可知,气候变暖会改变海洋的主要特征,并会影响浮游植物的生长。由此可判断“But phytoplankton are vulnerable to the oceans wamning trend”可知,浮游植物很容易受到海洋变暖趋势的影响。故选A。 (3)推理判断题。根据第四段中的“The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters ,such as those of the
14、 Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener”,可知Dutkiewicz的模型预测,目前只有少量浮游植物的蓝色区域可能会变得更蓝。但是在一些水域,比如北极,气候变暖会使浮游植物的生长条件更加成熟,而这些水域会变得更绿了”。由此可推断,浮游植物的生长条件更加成熟,浮游动植物就更多了,这些水域会变得更绿了。故选D。 (4)主旨大意题。第一段提出文章的主旨“By the end of the century. If not sooner, the w
15、orlds oceans will be bluer and greener thanks to a warming climate, according to a new study.”可知到本世纪末。一项新的研究表明,由于气候变暖,如果不尽快的话,世界上的海洋将会变得更蓝、更绿。再结合第三段“But phytoplankton are vulnerable to the oceans warning trendWarming changes key characteristics of the ocean and can affect phytoplankton growth, ”可知,“
16、浮游植物很容易受到海洋警告趋势的影响,变暖改变了海洋的关键特征,并能影响浮游植物的生长”。可知本文主要解释气候变化对海洋及其植物的影响。故选C。 【点评】本题考点涉及推理判断,词义猜测,段落大意和主旨大意四个题型的考查,是一篇科研类阅读,要求考生在捕捉细节信息的基础上,进一步根据上下文的逻辑关系,进行分析,推理,概括和归纳,从而选出正确答案。2(2019全国)阅读理解 Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year.
