1、核心素养拓展练核心素养拓展练 素养解读 2017 版普通高中课程标准首次提出“学科核心素养”。英语学科核心素养由 语言能力、文化意识、思维品质和学习能力构成。随之而来，以后的英语考试将更加坚持能 力立意，突出核心素养的考查。下面文段就是围绕“思维品质”这一学科素养展开，有助于 学生养成好习惯，从我做起，保护环境。 主题：地热资源 学科素养：思维品质 The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost ent
2、irely for more than a century.However，the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past.Many countries such as Germany and Sweden have already made significant efforts to fix this situation， employing numerous power plants working
3、 on the renewable resources of energy.The most effective among these resources is geothermal(地热的) energy. Geothermal energy does not depend on the worlds economic and political situation as strongly as fossil fuels do.Besides，extracting(提炼) fossil fuels adds to the price of energy produced from them
4、.Therefore， geothermal energy is much cheaper than traditional energy， saving up to 80% of the costs over fossil fuels. Being a renewable resource，geothermal energy produces less waste and pollution than traditional energy sources.In geothermal systems，carbon dioxide makes up about 10% of air produc
5、ed.Overall，in order to produce the electricity that can be used for one hour，the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases.For a comparison，a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere， and those power plants that
6、 work on coal(煤) produce an astonishing 3.6 pounds of greenhouse gases. Low costs are another reason why using geothermal power plants should be the first choice for many countries.Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or co
7、oling.Besides， geothermal equipment is less big： due to the very nature of geothermal energy，geothermal power plants have only a few moving parts，all of which can be easily sheltered inside a relatively small building.Whats more，the life span of geothermal equipment is rather long.All these make geo
8、thermal power stations easy to build and keep. 语篇解读 当前地热资源是最有效、最受欢迎的资源，它具有经济、环保、成本低等特点。 1.Fossil fuels are more expensive than geothermal energy partly because . A.it is free to use geothermal energy B.the production of fossil fuels costs a lot C.fossil fuels are nearly used up D.geothermal energy d
9、oesnt depend on political situation 答案 B 解析 细节理解题。根据第二段中的“extracting(提炼) fossil fuels adds to the price of energy produced from them”可知，提炼化石燃料成本较高，造成了化石燃料价格较高。故选 B。 2.According to Paragraph 3，what can be concluded from the comparison? A.Geothermal energy is environmentally friendly. B.Gas and coal a
10、re often used to produce electricity. C.Coal is much more efficient than gas. D.The geothermal systems dont produce harmful gases. 答案 A 解析 推理判断题。根据第三段中的“geothermal energy produces less waste and pollution than traditional energy sources”和下文地热系统和发电厂产生二氧化碳的数量比较可知， 地热是比 较环保的资源，故选 A。 3.Geothermal equipm
11、ent is usually not as big as that of traditional energy because of . A.the life span of geothermal equipment B.geothermal power plants C.the nature of geothermal energy D.the small buildings 答案 C 解析 细节理解题。根据最后一段第三句中的“due to the very nature of geothermal energy， geothermal power plants have only a fe
12、w moving parts”可知，由于地热资源的性质，地热设备 没有传统能源设备大，易移动。故选 C。 4.What is the main idea of this passage? A.Many countries have benefited from geothermal energy. B.Geothermal energy is well accepted. C.Fossil fuels are being run out of. D.Geothermal energy has many advantages. 答案 D 解析 主旨大意题。当前地热资源是最有效、最受欢迎的资源，它
13、具有经济、环保、成本低 等特点。本文主要介绍的就是地热能源的优点。故选 D。 Notes： .障碍词汇 1.efficient adj.高效的 2.geothermal adj.地热的 3.extract vt.提炼，提取 n.摘录，提取物 .长难句分析 Besides， geothermal equipment is less big： due to the very nature of geothermal energy， geothermal power plants have only a few moving parts，all of which can be easily sheltered inside a relatively small building. 分析 这是一个复合句。all of which 引导非限制性定语从句；due to 由于，是介词短语。 翻译 另外，地热设备不是很大：正是因为地热能的特性，地热发电厂只有几个可移动的部 分，这些部分都可以容易地放在一个相对较小的建筑物内。
