The trouble with these sources,however, is that they are not renewable (use again).&&&&Another way is energy conservation (节能), which means using energy more efficiently (有效地). Insome very cold countries people build special houses to save energy. They place materials between theinside and the outside of the walls of the house to keep the cold out and the warmth in. The house isheated by the lights, the body heat of the people and the other equipment in it.&&&&Finally, renewable energy sources are used even though they are often expensive to develop. One form of these isgeothermalenergy. In certain parts of the world the temperature of the earth increases thirtydegrees centigrade with each kilometer down. At six kilometres, therefore, it rises to nearly two hundreddegrees. To get the heat, water is pumped (压;抽) down into the rocks and back up to the surface. Heatfrom the earth is already used in certain countries.1. How many ways of dealing with the energy problem are discussed in the text？A. TwoB. ThreeC. FourD. Five.2. The writer tells about the "special houses" because they______.A. show the excellent skills of the buildersB. serve as an example of energy conservationC. are heated by different sources of energyD. are warmer than other types of houses3. The underlined words geothermal energy in the third paragraph mean ______.A. heat inside the earthB. underground sourceC. renewable sourceD. temperature of the earth4. At a place where the surface temperature is 15℃, how deep do you have to dig so as to&&&get a temperature of 75℃？A. One km.B. Two km.C. Three km.D. Four km.

According to Sun Landong, a meteorologist with the LanzhouMeteorology Observatory, visibility was less than 100 meters in Minqin, a Gansu county near InnerMongolia, because of sand. When visibility drops to less than 1 kilometer, it is called a sandstorm. Thesandstorm in Minqin blew up dust in neighboring towns, such as Baiyin, Wuwei, Jinchang and Lanzhou,the capital city of Gansu Province. Dust-laden winds also swept into Beijing. Brought by northwesterlyblowing at more than 20 meters per second, dust first reached the capital's suburbs at 7 a. m., downtownareas at 9 a. m. The winds, which died down during the night, brought the temperature down to as low as 8 0C below zero and many flights put off their planned time from the city's airport.&&&&It is quite rare for sandstorms, which are frequent between March and June, to happen in winter,when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there willbe more of them in the spring than last year, when they were serious, but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan (US 725 million) in preventing sandstorms in thecapital and has already set up a special team to make sure what causes them.1. What is the main idea of the passage?A. Sandstorms took place in Gansu.B. Sandstorms happened on the first day of the new year.C. Sandstorms are very serious,compared to last year.D. Experts are trying their best to determine the cause of the sandstorm formed this year2. Suppose the dust was 300 kilometers away from Beijing,it would reach Beijing about,&&&&&&&&hours&&&later if it travels at a speed of 20 meters per second?A. 4.2B. 1.5C. 2.0D. 2.53. Why did sandstorms begin in the winter this year?A. Because there was little snow this season.B. Because a lot of trees have been cut down.C. Because people took few measures to control them.D. It is not mentioned in the passage.4. Which of the following doesn't belong to the bad effect the sandstorms have done in Beijing?A. The temperature fell.B. Flights put off their time to take off.C. The air is dirty.D. People had three days off5.

Despite different ways to dispose of much of it in a green manner - largely throughencouraging recycling-its aging facilities such as the Powderhall landfill do not have the ability to dealwith it.&&&&The European Union (EU) has issued a new policy, regulating how such mountains of waste are to bedisposed of. The five councils ( Edinburgh, East Lothian, West Lothian, Midlothian and Borders ) facefines around ￡18 million a year from 2013 if they don't increase recycling levels and rely less on landfill. With this in mind, the councils got together with the idea of building a large incinerator plant (垃圾焚烧厂) to burn half of the waste produced in their districts. But this plan fell apart after the change of targetlevels by a new UK government waste policy which required that no more than 25% of the city's wasteshould be disposed of in this way by 2025.&&&&After the plan was abandoned, a private company which already transported millions of tons of thecity's waste by train to a landfill site near Dunbar, offered an alternative solution when it suggestedopening a huge waste site near Portobello.Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the EdinburghCouncil to accept the suggestion. But soon they turned it down - after 700 local objections reachedthem - because it would have meant hundreds of lorries a day making loud noise through heavilypopulated areas.&&&&That still leaves the council with a problem. By 2013, only 50% of 1995 levels of waste will beallowed to be sent to landfill. Even if recycling targets are met, there will still be a large amount ofrubbish to be burnt up. Due to this, Edinburgh and Midlothian councils have now decided to worktogether to build an incinerator plant as time to find a solution is fast running out.1. The main way of handling waste in a green manner in Edinburgh is ________.A. recycling&&B. restoring&&C. burying&&D. burning2. The five councils worked out a plan to build an incinerator plant to ________.A. reduce the cost of burying waste&&&&&&&&&&&&&&&&B. meet the EU requirementsC. speed up waste recycling&&&&&&&&&&&&&&&&&&&&&&D. replace landfill sites3. The city council of Edinburgh rejected the suggestion to open a huge landfill site near&&&Portobello because ________.A. it came from a private company&&&&&&&&&&&&&&B. the council was not interested in itC. it was not supported by EU&&&&&&&&&&&&&&&&&&D. the local people were against it4. What is the final decision of Edinburgh and Midlothian Councils?A. To open a new landfill nearby.&&&&&&&&&&B. To close the Powderhall landfill in 2015.C. To set up a plan for burning waste.&&&&&&D. To persuade people to deduce their waste.4&&&&请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词。注意:每空1个单词。&&&&When it comes to the world of computers, green computing is becoming one of the most populartrends. But, what is exactly is green computing?&&&&The term "green computing" is one that is being used in many different markets and areas all over theworld in today's global technology. Yet, many computer users out there aren't sure what it means. Greencomputing is actually pretty easy to explain and to do-it is basically learning to use computer resourcesmore efficiently (有效地) to help the environment as well as making energy savings. The main goal of agreen computing program is to reduce the use of energy and materials that harm the environment. Greencomputing helps to promote the use of biodegradable (生物所能分解的) products and recyclecomputer parts whenever possible.&&&&Green computing started as early as 1992, when the EPA created Energy Star, which is a voluntarylabeling program that promotes energy efficient computing equipment and technologies.&&&&It was because of this program that many computer manufacturers launched sleep mode and millionsof computer users around the world began to adopt this policy to help save energy when they were notusing their computers. The term "green computing" began to be used around the same time as well, andbegan to become a goal that more companies strive to meet over the years. There are several government agencies that have continued to help strive for better standards for computers and companies to helppromote green promoting. Energy Star was actually revised in&&October of 2006 to make the requirements stricter for computers,and also implemented a ranking&&system for products. Because of these newrequirements, there are over 20 states that have now established a special recycling program for oldcomputers and electronics to help with green computing.&&&&Many of today"s IT systems are beginning to rely on both people and hardware to help push theircomputer systems toward a more green computing system to help both the company and others. This is ahard balance to achieve, as it has to satisfy users, management, and regulatory compliance (顺从). Eventhe disposal of computer waste is all managed so that everyone in the circle is happy with the outcome.Many companies are learning the best ways that they call go greener when it comes to their computingand also help their business in the process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the worldand the requirements for new, better computers to help both the companies and the end users of theequipment, as well as our environment, are becoming more and more urgent.Green computing

So, in honor of Earth Day (which should really be every day), we think it's high time we find a few ways we can attempt to reduce our waste and our out-of-control use of resources. Here are 17 seriously easy things you can do every day to truly help save our Earth -- some even save you money!
Additionally,
that if you live in an urban area, you should try to push for your building to acquire a "cool roof." Researchers at the Lawrence Berkeley National Laboratory estimated that if 80 percent of roofs in tropical and temperate climate areas were painted white, it could offset the greenhouse gas emissions of 300 million automobiles around the world.
PPCPs (Pharmaceuticals and Personal Care Products as Pollutants) . These include over the counter and prescription drugs and cosmetics. The pollutants from these products are never absorbed by the human body, so they often run off into the wastewater and often end up causing ecological harm.
