houses may be more dangerous than the air outside.it may be one hundred times worse.indoor air pollution can cause a person to feel tired，to suffer eye pain，headache and other problems.some pollutants(污染物)can cause breathing disorders，diseases of blood and even cancer.most scientists agree that every modern house has some kind of indoor pollution.people have paid more attention to the problem now.it is true that when builders began making houses and offices they did not waste energy.to do this they built buildings that limited the flow of air between inside and outside.they also began using manmade building materials.these materials are now known to let out harmful gases.as the problem became more serious，scientists began searching for a way to deal with it.they discovered a natural pollution control system for building green plants.scientists do not really know how plants control air pollution.they believe that a plants leaves absorb or take in the pollutants.in exchange the plant lets out oxygen through its leaves and tiny organizations on its roots.scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space.studies of different plants show that each absorbs different chemicals.so the most effective way to clean the air is to use different kinds of plants.having green plants inside your house can make it a prettier and more healthy place.【解题导语】本文是一篇科技说明文。主要是讲室内空气污染现在已经被更多的人关注了，科学家们也正在寻找一系列的方法来解决这些问题。5generally speaking，indoor air pollution may be more harmful than the air outside because_aindoor air pollution can often make people seriously illbthere may be more harmful gases outside the buildingscmanmade building materials give off dangerous gasesdthe air indoors is polluted，which is very harmful解析：选c。细节理解题。由第三段最后两句they also began using manmade building materials.these materials are now known to let out harmful gases.可以知道室内空气污染比室外空气污染更严重的原因就是人工材料产生的气体。所以答案是c。6some kind of indoor pollution can be found in_aevery old housebevery modern house call kinds of housesdall kinds of offices解析：选b。细节理解题。由文章第二段最后一句可知，科学家相信每一橦现代房屋都存在空气污染。所以答案是b。7the indoor air pollution is caused by_athe manmade building materials and the limit of airflowbthe building way that the builders want to save energycthe building things that are made of manmade materialsdthe limit of the flow of air between inside and outside解析：选a。细节理解题。第三段的最后三句to do this they built buildings that limited the flow of air between inside and outside.they also began using manmade building materials.these materials are now known to let out harmful gases.可以知道，造成室内空气污染的原因，一个是limited the flow of air，一个是manmade material。所以答案选a。8the reason why we should use different kinds of plants to clean the air is that_aplants can let out all kinds of pollutants indoorsbplants may take in more oxygen which people needcplants can make our houses prettier and more healthydplants can absorb many kinds of harmful indoor chemicals解析：选d。细节理解题。由文章倒数二三句studies of different plants show that each absorbs different chemicals.so the most effective way to clean the air is to use different kinds of plants.可以得知，不同的植物能够吸收不同的化学气体，所以才要在房间内摆放不同的植物。所以答案是d。.七选五kids health ：four steps for fighting stresseverybody gets
