Every year on April 22, People all over the world celebrate Earth Day. It is a time to work to keep our earth clean. People plan projects to clean up the land, air and water.U.S. Senator Gaylord Nelson first thought of the idea for Earth Day in 1962 when he saw polluted rivers and cities with smoke. He needed to get support from Americans to clean up the earth. Finally, on April 22, 1970, 20 million Americans celebrated the first Earth Day! Now many countries around the world celebrate it, and you can, too.How can you celebrate Earth Day? Here are a few ideas:Join a clean-up project------Clean up your street or a favorite beach.Save energy------Turn off the lights when you leave a room, and use public transportation.Use less water.Reduce(减少)/ Reuse/ Recycle ------ Practice the three Rs: First, reduce how much you use.

因为篇幅有限，只列出部分考点，详细请访问。
政治经济类阅读
政治经济类阅读：该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。政治经济类阅读注意：1、要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识； 2、对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇；3、阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。
政治经济类阅读技巧：针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。1. 寻找主干：根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。2. 剔除从句：在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。3. 辨别分句：一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。4. 寻找关键词：如果一个句子看完，一点句意的感觉也没有，下下策就是抓住句中的关键词，通过关键词大体弄懂这个长句的意思。

Dazzling solar power singes fossil fuel industry
By Jayalakshmi K
Rooftop systems now sit atop roughly 12% of Hawaii's homes, according to the federal Energy Information Administration, by far the highest proportion in the nation. Residents need to get the utility's approval before installing photovoltaic rooftop solar systems. In areas like Mililani (above), the utility's power circuits had reached a threshold a year ago itself causing further additions of PV systems to compromise the grid
Solar energy is good for the planet, but not for the fossil fuel industry.Lengthy backlogs of solar rooftop applications for homes in Hawaii come as the latest evidence of disincentives for the growing solar market worldwide.Mirroring the popularity of rooftops in the US, almost 12% of Hawaii's homes boast a rooftop system.The state utility Hawaiian Electric Company says the growing solar home power connected to the grid is causing unanticipated voltage fluctuations that can overload circuits, burn lines and lead to brownouts or blackouts.When the amount of excess power fed into the grid exceeds what is used, the grid can become unstable. As more homes opt for grid connected solar power, it places pressures on old infrastructure like circuits and power lines, besides cutting into the utility's revenue.With a new rooftop solar system installed every three minutes in the US, home solar is rapidly spreading across the US too, causing utilities to reduce incentives, increase monthly surcharge and push solar companies out of the market.Attempts to smotherThere are now about 600,000 installed systems, and the number is expected to reach 3.3 million by 2020, according to the Solar Energy Industries Association.In many states, homes are being charged $3000 (?2016) for "interconnection studies" to control the rush for home-based power.In Arizona with more than 127,000 homes having rooftop arrays, the utilities initially asked for a $100-a-month surcharge, which was later reduced to about $5 a month. In Wisconsin, where rooftop solar is still relatively rare, regulators approved an annual fee of $182 a year.Net metering that allows consumers (turned producers) to sell excess power, often at lower rates than the utilities, is posing a threat to the survival of utilities.The utilities claim that homes are getting a free ride on the grid without paying up for construction and maintenance costs which have to be recovered. Solar advocates point that utilities are ignoring the load-reducing benefits of distributed energy in their planning.Battery storage technology or micro turbines could soon allow customers to be electric grid independent, say experts.Global sceneIn the developing world too, solar power is catching up fast.In India, several states have exempted solar projects from "wheeling" charges allowing solar developers to send power over the grid to commercial and industrial buyers for almost no charge.This is expected to prompt a backlash by utilities who lose out on their highest-paying clients.Between 2012 and 2014, solar capacity increased from 461 megawatts to over three gigawatts with another two gigawatts to be added this year. The price of solar power has fast fallen by a third in three years.Prime Minister Narendra Modi has set an ambitious goal to install 100 gigawatts of solar power capacity — over 30 times more than India has now — by 2022.Meanwhile, China connected 5.04 gigawatts of solar capacity to its grids in the three months ended 31 March, notching a total 33 gigawatts of solar-power supply.The global installed capacity of solar electricity has increased by six times to 135GW in 2013 from 23GW in 2010.Falling pricesSolar power is fast approaching grid parity with fossil fuel power, and in some cases falling even lower as wafers go thinner and more effective in sunlight conversion. Solar photovoltaic prices have fallen by 80% since 2008.A report released late last year by German think tank Agora Energiewende, predicted solar energy would become the cheapest source of electricity in many parts of the world within the next 10 years.In such a scenario, a repeat of what is being seen in the US and Hawaii can be expected across the globe as the fossil fuel industry and utilities scramble to tackle the solar home insurgency threat.Hopefully, the efforts to clean energy will not be derailed. The warming world cannot afford that.World electricity generation is forecast to grow by 67% from 22,126 terawatt-hour in 2011 to 37,000 in 2030. A major part of this additional capacity will be met by fossil fuels.Electricity production from fossil fuels accounts for more than 40% of man-made CO2 emissions.These emissions need to drop fast and for that the world has to be weaned away from fossil fuels by the end of the century to avoid irreversible climate change.As the world celebrates another Earth Day on 22 April, it is time to shed old habits and adopt new and clean ways.There is enough and more of solar energy to cater to the world's needs. Sunlight that falls on the earth's surface in 40 minutes equals the total annual energy consumption of the planet's humans. Just 1% of that is currently used to generate power.It is time to exploit that abundance, not sabotage.More about solar energy Solar energy to be cheapest power source in 10 years India raises solar investment target to $100bn by 2022 Cheaper and More Efficient Perovskite Solar Cell Developed China plans massive solar power station in space by 2050 India: World's largest solar plant that will generate 750 MW of power commissioned Record solar efficiency above 40% reported by New South Wales researchers
