二、综合题
36. 阅读图文材料，完成下列要求。
近年来，云计算、大数据、人工智能已经成为世界经济发展的新引擎，各行各业的大发展都需要有数据中心的支撑。数据中心是指在一个物理空间内实现信息的集中处理、存储、传输、交换和管理，它包括数万台计算机设备、服务器设备、网络设备、存储设备、供电系统和冷却系统等。
美国达尔斯市(如下图所示)位于哥伦比亚河峡谷的出口处，是因兴建电站而发展起来的小镇。2005年初，当地政府批准谷歌公司以187万美元购买12万平方米土地，兴建全球数据处理能力最强的超大型数据中心。

(2)分析数据中心落户达尔斯市的原因。(8分)
(3)阐述数据中心建设对达尔斯市经济发展的有利影响。(6分)
(4)为适应绿色环保发展的要求，推测全球数据中心布局的发展趋势。(4分)
37. 阅读图文材料，完成下列要求去。(22分)
热量资源是指某一地区在特定的气候条件下所能提供的热量多少。一般把气温高于0℃的部分，如无霜期、≥10℃的积温等“热量”，看作农业生产的有利条件。而把低于0℃的部分，如霜期等“冷量”，看作农业生产的限制条件，甚至作为灾害。
河北省沧州市海兴县由于地下水盐度高，缺乏淡水资源，盐碱地广布。海兴县根据盐度与结(融)冰的关系(如下图所示)，进行咸淡分离，成功改造了盐碱地。他们利用“冷量”资源的经验是：在每年10月平整高低不平的土地，1月份气温低于℃后，开始使用海水灌溉农田，直至海水结冰厚度达20~25厘米为止。3月份开春冰层完全融化下渗后，及时全田覆盖农用薄膜，然后种植作物。
(1) 描述盐度与结(融)冰的关系。(6分)
(2) 分析海兴县农田上覆冰层盐度垂直分布的特点。(6分)
(3) 海兴县利用“冷量”资源，海水灌溉农田成功“脱盐”，阐释其原理。(6分)
(4) 说明海兴县开春后全田覆盖薄膜的作用。(4分)
43. 【地理——选修3：旅游地理】(10分)
邮轮旅游是用邮轮将一个或多个旅游目的地联系起来的旅游方式。现代邮轮 (如下图所示)就像是流动型的大酒店，集食、住、行、娱、购于一身，使游客获得舒适的享受。近年来，随着我国经济高速发展，邮轮旅游风潮正在兴起，使我国旅游产业从游览观光逐渐向观光结合休闲度假的方式转型升级发展。
与传统旅游方式比较，分析邮轮旅游方式的优点。
44. 【地理——选修5：环境保护】(10分)
永久冻土是指0℃以下，并含有冰的各种岩石和土壤。它已经被冰封数千年、甚至几十万年，里面充满着死亡植物等有机质。青藏高原是多条大河的发源地，由于海拔高、气温低，拥有面积广袤的永久冻土层。最新研究结果表明：青藏高原上主要河流温室气体(二氧化碳、甲烷)的排放通量处于世界的中高水平，引起了一系列环境问题。
分析青藏高原上主要河流温室气体排放通量大的原因及其影响。

关于生命的六年级英语作文带翻译 生命给予我们的是有限的，但是我们可以努力使它发光。以下是带来的关于生命的六年级英语，希望对你有帮助。 Compared to the universe, our lives are really short, just like a meter. But the meaning of life doesn’t depend on its length but contributions. For example, Marie Curie, in order to find the radium, she devoted her whole life to the research. Though the radioactive element had shorter her life, she never gave up her mind to serve the world. Aording to her story, I conclude that the first meaning of life is contribution. The standard of judging a life isn’t how much he asks for but how much he gives away. 和宇宙相比，我们的生命其实很短暂，仿佛只有一米。但是生命的意义并不取决于它的长度，而取决于它的贡献。比如，居里夫人为了发现镭把她的毕生都奉献到研究中。尽管放射性元素缩短了她的生命，但她从来没有放弃为世界服务的决心。根据她的故事，我可以得出这样一个结论，生命的最初意义在于奉献。判断一个人生命的标准不是他索取了多少而是他贡献了多少。
广州市2020年高三第二次模拟考试 英语 第二部分阅读理解(共两节，满分40分) 第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 WENQIANG A We can all think of times when people didn't make remembering easy. Directions given at machine-gun speed. New people introduced in a flood of names and handshakes. Whenever information is passed between people, it’s all too easy for it to go in one ear and straight out of the other. Thankfully, the opposite is also true. Look around you, and you’ll see parents who can get their children to rem ember exactly what they were told; advertisers who know how to imprint their sales messages on our brains. So, how do they do? Their secrets can be summed up in four simple words: focus, imagery, reasons and engagement. FOCUS means ensuring that the person you’re talking to can concentrate on learning. Choose your moment carefully. Check that they can properly hear or see the information. Communicate slowly and clearly enough for their memory to cope. IMAGERY helps information to stick. Do everything your can to make other people “see”the ideas you’re giving them. Add visual details to directions, and illustrate abstract concepts with metaphors. REASONS to remember help people to put in the mental effort. So, make it clear that your words are important, and be explicit about why. Maybe this information will save them time, protectthem from embarrassment, or let them enjoy a particular experience or event. EMGAGEMENT requires you to ask questions. Point out links between new concepts and things listeners already know. Activate their senses, spark their curiosity, get them doing something physical, or simply make them laugh. The next time you’ve got an important message to pass on, put some of these techniques to the test. You’ll discover that there are benefits on both sides when you know how to FIRE people’s memories into action. 21. What is the main purpose of the text? A.To report new research. B.To provide some advice. C.To explain a problem. D.To define some terms. 22. How can you do to help a listener “focus” on w hat you are saying? A.Select the appropriate time to raise the topic. B.Do something humorous to get their attention. C.Make sure the information provided is correct.
