Because global warming may be the single largest threat to our planet（the earth）. Low-lying nations could be awash in seawater, rain and drought patterns across the world could change, hurricanes could become more frequent, and El Ninos could become more intense. 2. Paragraph 3. Our factories, power plants, and cars burn coal and gasoline and spit out carbon dioxide, produce methane by allowing our trash to decompose in landfills and by breeding large herds of methane-belching cattle, and release nitrogen oxide by using nitrogen-based fertilizers. 3. Paragraph 4. The increased concentrations of greenhouse gases prevent additional thermal radiation from leaving the Earth, so cause the global warming. 4. Paragraph 7. A slight increase in heat and rain in equatorial regions would increase vector-borne带菌媒介引起的diseases such as malaria; more intense rains and hurricanes could cause more severe flooding and more deaths in coastal regions and along riverbeds; even a moderate rise in sea level could threaten the low-lying islands; hotter summers couldlead to more cases of heatstroke, hospital admissions and deaths among vulnerable people with heart problems or respiratory problems. 5. Paragraph 8 and 10. We can curb our consumption of fossil fuels and use technologies to reduce the emission of heat-trapping gases like carbon二氧化碳 dioxide, methane, and nitrous oxides, and protect the forests in the world, and we can also advocate policies that will combat global warming over the long term, things like clean cars, environmentally responsible renewable energy technologies, and stopping the clear-cutting of valuable forests. IV. 1. Global warming will probably be the most serious threat to our Earth, if we do not take into account of some other possible disasters, such as another world war, collision of our Earth with some small orbiting planet, or spread of incurable diseases. 2. In terms of human health, the people of the poorer countries will suffer most, because their countries do not have money to protect them when climate changes. Structural analysis Sub-ideas in the second part. 1) the causes of the rising concentration of greenhouse gases in the atmosphere (Paragraphs 3 and 4)

现代汉语课后习题答案全

第一章绪论”习题答案 “绪论"思考和练习一 一、什么是现代汉民族共同语？它是怎样形成的？ 现代汉民族的共同语就是“以北京语音为标准音，以北方话为基础方言，以典范的现代白话文著作为语法规范的普通话”。 现代汉民族共同语是在北方话基础上形成的。在形成的过程中，北京话占有特殊的地位。早在唐代，北京已是北方军事要镇.北京是辽、金、元、明、清各代的都城。近千年来，北京一直是我国政治、经济、文化的中心,北京话的影响越来越大。一方面,它作为官府的通用语言传播到了全国各地，发展成为“官话"，另一方面，白话文学作品更多地接受了北京话的影响。 本世纪初，特别是“五四”运动以后，掀起了“白话文运动”，动摇了文言文的统治地位;另一方面，“国语运动"的开展促使北京语音成为全民族共同语的标准音。两个运动互相推动和影响，这就使得书面语和口语接近起来，形成了现代汉民族共同语。 二、共同语和方言的关系是怎样的? 方言是一种民族语言的地方分支或变体，是局部地区的人们所使用的语言。一民族语言的共同语，则是通用于这个民族全体成员的语言。对于各地方言来说，规范化的共同语是民族语言的高级形式，它比任何方言都富有表现力.共同语形成后，对于方言的语音、词汇、语法都有一定的影响。它的词语经常传播到各方言中去.规范化的共同语，往往促使地域方言向它靠拢，对方言的发展起一种制约的作用。与此同时，共同语也要从方言中吸收种种语言成分，以丰富和发展自己。但是,地域方言间差异的缩小,以至于消失，则须经过一个长期而复杂的过程. “第二章语音"习题答案 “语音”思考和练习一 四、语音具有物理属性、生理属性、社会属性. “语音”思考和练习二 二、普通话声母的发音部位和发音方法各包括哪几种？请画成一个总表把声母填上。 普通话声母的发音部位包括双唇、唇齿、舌尖前、舌尖中、舌尖后、舌面、舌根七种。发音方法，从阻碍的方式看，包括塞音、擦音、塞擦音、鼻音、边音五种；从声带是否颤动看，包括清音、浊音两种；从气流的强弱看，包括送气音、不送气音两种.声母总表（略）。 三、根据所提供的发音部位和发音方法，在下面横杠上填上相应的声母. 1．双唇送气清塞音是p。
