This leaflet will tell you the most important things to remember if you have to put a fire out.Water exting
10、uishersYou can put most fires out with water extinguishers. However, you should not use water extinguishers if the fire involves electrical equipment or if it has been started by flammable (易燃的) liquids such as petrol.As in all fires, make sure that the wind is behind you if you do this, the smoke w
11、ill blow away from you. Point the jet of water at the bottom of the fire and move it slowly higher.Remember that you should only use extinguishers for small fires. If there is any danger of the fire spreading to anything that can explode, you should not try to put the fire out yourself. Instead, lea
12、ve the building immediately, and call the fire brigade.Foam (泡沫) extinguishersYou can use a foam extinguisher for fire caused by burning liquids such as petrol. Never point the jet directly into the liquid itself, as this may make it splash and spread the fire. Instead, try and point the extinguishe
13、r up into the air so that the foam goes up and falls on top of the burning liquid. Whatever the kind of fire, do not stand up straight if you can stay down, this will help you to avoid the smoke, and you may be able to get closer to the fire. Get out of the building at once if you think your escape
14、route might be cut off by smoke or fire. Carbon Dioxide (CO2) extinguishers Some fire extinguishers are filled with a gas called carbon dioxide. You can use these to put out fires which have been caused either by electrical equipment or flammable liquids. If the fire has been caused by electrical eq
15、uipment, switch the equipment off and point the extinguisher straight at the fire. If the fire has been caused by a liquid like petrol, point the extinguisher at the nearest edge of the fire, and move it from side to side. Remember, never stay in a building if it is dangerous to do so, or if the fir

It makes us feel good when we feel the warmth of its rays on our shoulders. We store the energy from the sun to help build and heat our houses.Without sunlight w
25、e would not be able to survive. Sunlight gives balance. All living things live in a food chain and at the beginning of the food chain comes the plant which absorbs sunlight and transforms light energy into chemical energy, which will then be absorbed by another life to be turned into a new kind of e
26、nergy and so on.One of the benefits that we can get from sunlight is that we can receive vitamin D from sunlight. It helps us to keep a healthy body, control the amount of minerals in the body, which is needed to help keep our bones and teeth in good condition and helps to keep a well-balanced mind.
27、Different places on the earth receive varying degrees of sunlight, which will decide the regions climate. For example, the farther away it is from the equator (赤道), the sharper the angle (角度) of the suns rays that reach it, which means that sunlight coverage will be more spread out, and receive less

Nanowires are thin wires about one-hundredth the width of a human hair, used as electronic parts, and also as solar cells.“On Mars, about 96% of the atmosphere is CO2. Basically, all you need is these nanowires to take in the solar energy and pass it on t

Thats why this version is highly attractive.”The only other requirement, besides sunlight, is water, which on Mars is relatively more than enough in the polar ice caps and likely lies frozen underground over most of the planet, said Yang.It works like photosynthesis (光合作用)
35、, which plants naturally employ to change CO2 and water into carbon compounds, mostly sugar and carbohydrates. Plants, however, have a quite low efficiency (效率), usually changing less than one-half percent of solar energy into carbon compounds. Yangs system is comparable to the plant that best chang

83、事项。21细节理解题。根据文中“You can put most fires out with water extinguishers.”（你用水灭火器可以扑灭大部分的火）可知，水灭火器只能扑灭大部分的火，所以A项You cannot put all fires out with water extinguishers.你不能用水灭火器扑灭所有的火，与原文意思相符，所以A项正确；根据文中“Whatever the kind of fire, do not stand up straight if you can stay down, this will help you to avoid th
84、e smoke”（不论什么样的火，不要一直站着-如果你能趴下，这样可以帮你避免烟）可知，趴下是可以有效避免烟的伤害的，所以B项In case of fire, stay down to protect yourself from the smoke.如果有火，趴下可以让你免受烟的伤害，与文中意思相符，所以B项正确；根据文中“If there is any danger of the fire spreading to anything that can explode, you should not try to put the fire out yourself. Instead, leav
85、e the building immediately, and call the fire brigade.”（当所处火灾有进一步的扩散到可能引起爆炸的任何东西时，你不应该独自灭火，而是应该立即离开那个建筑物并且给消防队打电话。）可知，火灾有进一步危险的时候，应该先自保离开火灾现场，并打电话报火警，所以C项，If the fire might cause any further explosion, ask for professional help.如果火可能会引起进一步的爆炸，向专业人求助，与原文意思相符，所以C项正确；根据文中“You can use a foam extinguishe
86、r for fire caused by burning liquids such as petrol.”（当出现像汽油等液体引起的火灾时可以用泡沫灭火器来灭火）可知，泡沫灭火器是针对液体引起的火灾的，而D项，Foam extinguishers are for fires caused by electrical equipment.泡沫灭火器用来扑灭由电器引起的火灾，与原文意思不符，所以D项错误，综上所述，只有D项不正确，故选D项。22推理判断题。纵观全文可知，本文主要介绍不同的灭火器灭火，但不同灭火器的使用方法会因为不同类型的火灾也有所不同，所以在灭火时一定要正确使用灭火器，那么言外之意
87、就是，如果没有正确使用灭火器也可能会使火灾更加恶化，所以A项，Inappropriate use of fire extinguishers might make things worse.不正确的使用灭火器可能会使事情恶化，是正确的；根据文中“Get out of the building at once if you think your escape route might be cut off by smoke or fire. ”（如果逃跑路线被火或者烟切断，你应该立刻离开楼里），可知B项，You should stay in the building if your escape
88、route is cut off. 如果逃跑路线被切断，你应该待在楼里，与原文不符，所以B项错误；C项Standing close to an exit will absolutely guarantee your safety in a fire.在火灾中，站在靠近出口的地方可以绝对保证你的安全，说法太绝对，所以C项错误；D项Firefighting is a complicated job that can only be done by fire brigades.灭火是一项非常复杂的工作，所以只能由消防队来做这个工作。从文中介绍不同的灭火器使用方法可以知道，灭火并没有很复杂，只是需要我
