The company can constantly monitor the level of heat and energy and adjust __________.A． accordinglyB． basicallyC． conventionallyD． subjectively
There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.Another way is energy conservation ( 节能 ), which means using energy more efficiently ( 有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated 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 is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped ( 压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.1、How many ways of dealing with the energy problem are discussed in the text? ( )A、Two.B、Three.C、Four.D、Five.2、From the text we learn that coal( ).A、is quite easy to produceB、is not used most efficientlyC、is the most common source of energyD、could be renewed only by new technology3、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 houses4、The underlined words "geothermal energy" in the third paragraph mean ( ).A、renewable sourceB、 underground sourceC、 heat inside the earthD、 temperature of the earth5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ? ( )A、One km.B、 Two km.C、 Three km.D、 Four km

The world's energy watchdog has sounded the alarm over a"worrying"pause in the shift to clean energy after global investment in renewables fell 7%to$318bn（~240bn）last year.The International Energy Agency said the decline is set to continue int0 2018,threatening energy security,climate change and air pollution goals.Fossil fuels increased their share of energy supply investment for the first time since 2014,to$790bn,and will play a significant role for years on current trends,the IEA said.Investment in coal power dropped sharply but was offset by an uptick in oil and gas spending,the World Energy Investment repoit found..Dr Fatih Birol,the executive director of the IEA,said of the renewables fall:"We are seeing a decrease,which is disappointing.And more disappointing is we see the signs this decline may continue this year-this is a worrying trend."Fossil fuels'share of energy investment needs to drop t0 40%by 2030 to meet climate targets but instead rose fractionally t0 59%in 2017.World leaders'warm words on renewables and energy efficiency needed to be matched with action,Birol said,urging govemments to create less investment uncertainty for green energy.Globally,energy investment fell 2%to$1.8tn in 2017,with electricity taking a bigger share than oil and gas for the second year in a row.The decline in renewable power generation spending was mostly down to falls in wind power and hydro but solar hit record levels despite becoming cheaper to install.While coal investment fell to its lowest level in 10 years,spending on gas-fired power stations rose 40%.Nuclear power fell sharply to the lowest level of investment in five years.In the oil and gas industry,rising prices have helped investment in production rise 4%last year and is expected to grow 5%this year.The US's shale boom will drive much of the groivth,and frackers are on track to achieve positive free cashflow this year,for the first time.The US is not expected to pump enough extra crude to bring down oil prices,though.Birol said"Us shale growth is very welcome growth for badly needed additions but this growth alone will not be enough to balance out the markets.Outside the US,investment in conventional oil and gas projects remains subdued and Birol said the world faced"major difficulties"if investment was not stepped u Motorists spent S 43bn on fully electric cars and plug-in hybrids last year,accounting for half of global growth in car sales.However,the battery-powered cars are not seriously denting oil demand yet the IEA said Governments are increasing investment in energy markets,either directly through state-owned firms or indirectly via investments policies and regulation,which Birol said was a surprising developmentThe emerging worry about energy is thatA.the current short supply of the clean energy worldwideB.the failure to transition to renewable energy sources,C.the decrease of the investment to the energy exploitationD.people's consciousness of environmental protection
共用题干Electromagnetic Energy1 White light seems to be a combination of all colors.The energy that comes from a source of light isnot limited to the kind of energy you can see.Heat is given off by a flame or an electric light.On a cloudy day it is possible to get a sunburn even though you feel cool.Visible light and the kind of energy that produce warmth and sunburn are examples of electromagnetic energy.2 The sun is 93 million miles away from the earth.Yct we can use energy from die sun because elec-tromagnetic energy travels through space.3 Many other kinds of energy are also types of electromagnetic energy.Radio,television,and radar signais travel from transmitters to receivers as low-energy electromagnetic waves. Infrared（红外线的）radiation is an electromagnetic wave.When it is absorbed by matter,heat is produced.Wayes of infrared and visible light have more energy than waves of radio,television,or radar. Ultraviolet rays（紫外线）and X-rays are eleetro-magnetic waves with even greater amounts of energy.Infrared radiation is used in cooking food and heating buildings.Sunlight and electric lights are part of our requirements for normal living. Ultraviolet radiation is useful in killing certain disease organisms.X-rays and gamma rays have so much energy that they travel right through solid objects.They can be used to detect and treat cancer。 X-rays are used in industry to find hiddencracks in metal,and in medicine to reveal broken bones.4 Usually we use electricity to generate electromagnetic energy.The source of most of our energy is the sun.Heat from the sun causes water to evaporate.When the water falls to the earth as rain,some of it is trapped behind dams and then used to operate electric generators,Other generators are powered by coal,but the energy stored in coal came from the sun,too.5 Until recently,the source of the tremendous amount of energy given off by the sun was a puzzle.If the sun depended on chemical reactions,it would have used up all its energy long ago.Experiments with electromagnetic radiation led to the theory that mass can be converted into energy．入bout forty years after the theory was proposed , nuclear energy was harnessed（利用）by man. Chemical energy comes from electron （电子）rearrangement. Nuclear energy comes from a change in the nucleus of an atom. Compared with chemi- cal reactions,nuclear reactions release millions of times more energy per pound of fuel.We now believe that the sun's energy comes from the nuclear reactions in which hydrogen is changed into helium（氦）.6 Nuclear energy is beginning to compete with coal as an economical source of power to generate elec- tricity.It is also being used to operate engines in large ships.Scientists continue to seek new and bettermethods of obtaining and using energy.We can use energy from the sun because_______________.A:electromagnetic energyB:electromagnetic energy travels through spaceC:came from the sunD:when a change in the nucleus of an atom takes placeE:whlen the sunrays are fierce F:chemical energy is generated
共用题干Green Energy1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural（建筑学的）design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.Greenhouse gases are thought to be causing______.A:global warmingB:carbon emissionC:lower waste outputD:a green energy sourceE:fossil fuels F: clean fuels
