Nowadays, it is commonly acknowledged that to maintain permanent peace and development, environmental problems must be solved with highest priority. In my opinio

13、n, to control global warming, government should carry out sensible policies and common people also should take their resibonsibilities.I can remember big snow came every year when I was a child, and the weather was so cold that I couldnt go outdoors without my scarf and hat. But these years, big sno

14、ws are hard to see, and even in December, you neednt wear too much because its not cold at all. The climate is changing. In the past decades, global warming arouse many countries attention and they do took some measures to ease this problem. However, though the Kyoto Protocol was signed, some countr

15、ies are not willing to hold their pace of economic development. To drive the global warming under control, we still have a long way to go.Governments are the main force in the combat against global warming. On the issues concerning global warming, the variety of attitudes toward global warming is a

16、greatest obstacle for us to win this combat. So, at first, all the countries must reach an agreement on striking a balance between developing economy and solving this environmental problem. Then, some effective policies should be adopted to reduce the emission of the greenhouse gases. Common peoples

17、 involvements are the key to ease the global warming. One persons ablity is slight, but if every one can make a little effort, the achivement will be incredible. What can we do for it? I think first, we can learn something about global warming, to be aware of it and to know our resiponsiblities to t

With the development of economy, the emission of the greenhouse gas, consistin

20、g of about 70% carbon dioxide, has been steadily increased, contributing greatly to the global warming. The increase in the temperature of the earth has caused many harmful effects. It melts the ice caps, raising sea levels. It disturbs weather patterns, causing frequent natural disasters such as fl

21、oods, droughts, severe storms, hurricanes (飓风), and so on. Actually, its easy for everyone to do something to save energy and reduce the emission of greenhouse gas. For example, turn off an electrical appliance if it is not used. Walking, cycling, carpooling or using public transportation instead of

22、 using motor vehicles are all good ways to reduce the emission of carbon dioxide. We are also supposed to plant trees and preserve forests. Every individual counts and individuals together makes a big difference.作文七倡议书1 据报道，在过去的十年间，北极圈内的平均气温比以前升高了23摄氏度。 2 2009年12月的哥本哈根世界气候峰会要求各国减少温室气体排放，拯救地球。 3 2010

So lets take action from now on! lets save the earth.作文八Ladies and Gentlemen,Good morning. Im Li Hua from Fujian, China. Its my great honor to be here to say something

26、about the global water shortage and ways of dealing with it.As we know, the global water shortage is becoming increasingly sever mainly due to global warming, environmental pollution and the ever-increasing population. Therefore, its high time we did something about it.Firstly, an effective way, I t

27、hink, is to reserve water in a scientific way for future use. Secondly, new methods need to be developed to use the existing waster resources, for example, turning sea water into fresh water. Thirdly, we must stoop water pollution by law. Last but not least, its everyones responsibility to make good

28、 use of water, such as recycling and saving water in our daily life.In conclusion, people around the world should be aware of the real situation of water shortage, protect the present water resources and explore potential ones scientifically.作文九global warming and our lifeGlobal warming has quickly b

29、ecome one of the most heated issues. With the development of the economy, the emission of the green house gas, consisting of about 70% carbon dioxide, has been increased, attributing greatly to the global warming.Global warming is the slow and steady increase in the temperature of earth and its atmo

30、sphere. The increase in the temperature of earth has caused many effects like the melting of ice in Polar Regions, increase in disease occurrences, drastic climatic changes and rise of the sea level.As the effects of global warming is becoming more and more evident, many of us have started to realiz

31、e that steps have to be taken to control Global warming, such as the usage of clean energy resources and the alternative of motor.作文十One possible version: Dear editor, The curtain went down on the Copenhagen climate summit, leaving the world concerned more about global warming once again. As is well

32、 known, it is human activity that has contributed to this problem. The burning of fossil fuels like coal, natural gas and oil produces greenhouse gases. When huge quantities of extra carbon dioxide are put into the atmosphere, more heat energy tends to be trapped in it causing the global temperature

33、 to go up. However, the attitudes of scientists towards this rise are completely different.

39、，肝主筋，人之运动皆由于筋，故为罢极之本”。人体肝脏的功能活动也必阿胶, 味甘性平, 入肺、肝、肾经, 具有补血止血、滋阴润肺的功效。神农本阿胶,又称驴皮胶,为马科动物驴的皮去毛后熬制而成的胶块,是中国医药宝库中阿胶、熟地配伍能使补而不滋腻, 共奏益气补血之功, 主要治疗各种原因导致的气血阿胶对细有促进作用；提示阿胶能提高机体免疫功能。 另外阿胶具阿胶具有很好的止血作用，常用来治疗阴虚火旺、血脉受伤造成的出血。比如，阿胶能治疗缺铁性贫血，再生障碍性贫血等贫血症状，阿胶对血小板减少，白细阿胶是一类明胶蛋白，经水解分离得到多种氨基酸，阿胶具有很多的药理作用和阿胶又称驴皮胶, 为马科动物驴的皮去毛后

40、熬制而成的胶块。中药界有句口头禅:阿胶中的营养成分比较多，主要有蛋白质、多肽、氨基酸、金属元素、硫酸皮肤。把阿胶应用于运动员或人群中的实践应用性，具有很大的潜力和市场前景，白血病、鼻咽癌、食道癌、肺癌、乳腺癌等。阿胶不温不燥，老少皆宜，一年四季均伴随现代竞技体育的强度越来越大，运动员在大运动量训练后出现的各种疲劳征象，胞减少等症也具有效果明显效果；另外，经配伍，阿胶可用来治疗多种出血症。医学保健作用，阿胶具有耐缺氧、耐寒冷、抗疲劳和增强免疫功能作用；同时，阿胶具有本文的目的意义有以下两个方面：一是通过阿胶的抗疲劳能力，来进一本以运动性疲劳相关症状明显的篮球运动员为对象，以谷丙转氨酶、谷表明，阿

41、胶还用于治疗妊娠期胎动不安，先兆流产,习惯性流产等。对于月经病步了解运动员服用阿胶以后，不但能够使男女运动员的谷草转氨酶含量水平、谷丙转参促进人体对糖原和三磷酸腺苷等能源物质的合理利用, 并使剧烈运动时产生的乳草经将其列为上品。本草纲目载阿胶“疗吐血衄血, 血淋尿血, 肠风下痢, 女草转氨酶、谷酰转肽酶、总胆红素、白蛋白和白蛋白/球蛋白含量水平为测定指标，产生运动。从中医学的观点来看，筋就是聚集在一起的肌肉束，膜是筋的延长和扩布；常所说的肌腱和韧带等器官，韧带和肌腱坚韧有力。通过韧带和肌腱伸缩牵拉骨骼肌充在筋”, 也就说明了筋的功能受到肝脏的调节, 所以, 医家大多从筋与肝相关的角除运动后的疲

42、劳, 已经成为运动医学领域的热点,而中医药在改善、消除运动性促进肌肉和肝脏有氧氧化能力的作用。 红景天圣露能促进机体运动后的恢复和消除促进血液凝固和抗贫血作用，有提高血红蛋白红细胞，白细胞和血小板的作用。到影响。的变化, 主要表现为部分肝细胞破裂, 内容物进入窦状隙, 未受损的肝细胞糖原明的核心问题之一, 也是运动训练学所要克服的核心问题之一, 疲劳是机体的一的滋补类药品；因始产于聊城东阿，故名阿胶，距今已有两千多年的生产历史；最早低分子肽含量分别是15%45%、10.97%13.18% 。霍光华采用标准水解法和氨基低运动后血清尿素氮含量； 加速体内尿素氮及血乳酸的清除速率；提高小鼠的游泳点、

43、“肝之合筋”的观点、“肝者,其充在筋” 的观点、“食气入胃,散精于肝,淫气于动领域的广泛应用。动性疲劳关系最为密切者当首推肝脏。动性疲劳后机体恢复作用和机制的十分活跃。动员和贮备，以及机体对运动刺激的适应和运动后的疲劳的恢复起到重要的促进作用度阐述肝与疲劳的关系, 其实肝尚可通过脏腑气血等多个途径影响疲劳感的产生和度的DS 标准液, 加适量天青试液, 536nm 处测定吸收值, 建立工作曲线回归方程。对于运动产生的机理, 中医学解释比较通俗易懂, 即：韧带和肌腱的伸缩牵拉骨对运动性疲劳的多集中于中枢疲劳与外周肌肉疲劳，而较少涉及肝脏实质器而略于补立法，以健脾保肝、补中益气组方的确是防治运动性疲

44、劳的一条新思新。故发挥和延缓运动性疲劳的产生都能起积极而有效的作用。总之,体力和脑力的产生均复的适应能力。复方阿胶浆是由阿胶、红参、党参、熟地、山楂等药组成, 主入肝、脾两经。方肝，人动血运于经,”的论述。明确指出运动能力与肝和血密切相关。这种“动则血肝脾同处于中心位置，共同掌管着气化的职责，所以运动性疲劳的气虚神乏大多是由肝损害可导致动物运动能力下降, 也有大量实验观察了急性力竭疲劳对动物肝脏的肝糖原、肌糖元含量下降, 其程度随着衰竭运动次数增加而增加。林华等通过对衰肝有关，由此可以推测神经递质、激素的释放等生理活动均同肝脏有密切关系。再者肝与筋的关系非常密切，在许多著作中都阐述了这一观点。

45、如“肝主筋” 的观肝脏对内分泌具有促进作用。中医认为，胆汁的分泌、女子的排卵、男子的排精均主藏血、主筋，为“罴极之本”，有储藏营血与调节血量的作用,是提供运动所肝主疏泄，调畅气机，对气血津液的生成、输布和代谢有着重要意义。就运动生高山红景天在疲劳情况下能提高机体持续工作的时间，维持血压、心率的正常水高小鼠肝糖原的储备量； 降低运动后血清尿素氮含量；加速体内尿素氮及血乳酸的骼肌产生运动。素问六节藏象论曰：“肝者,罢极之本,魂之居也, 其华在爪, 其个特别复杂的生理生化过程。 总的说来，疲劳可分为生理疲劳和心理疲劳。 1982工作能力的作用。强力宝能促进肌肉和肝脏有氧氧化能力的作用。参宝片也能具有

46、官的疲劳。肝脏作为人体重要的脏器，与运动性疲劳的关系极为密切。国际运动医学协会主席普罗科朴(Polo1Capur) 认为运动性疲劳问题是运动医学过度的训练、残酷的比赛引起的缺氧、强应激反应会导致机体的神经内分泌系统、心过去一段时间，抗运动性疲劳传统上单纯采用补的模式,现在，中医药抗疲劳出还认为“食气入胃，全赖肝木之气以疏泄之，而水谷乃化，气血方得以运生”，说明和血虚者，如服用阿胶补益，也具有良好的效果。临床上充分发挥阿胶的养血、补血、恢复正常，促进酸碱平衡的恢复，减少碱性物质的消耗。机体的血量增加,以便增加通气/血流比值。肝内所贮存的血液就会更多的向机体全身肌腱和韧带等器官的力量。筋和筋膜向内连着五脏六腑，肝将脾输送来的精微之气浸、涉水等劳动或运动都称为“劳”, 而竞技体育由于其具有大运动量、高强度的加。剑, 便无踪无影。阿娇日日夜夜在狮耳山、狼溪河附近狩猎。最后, 用利剑杀死了一奖牌呢?毫无疑问是靠长时间艰苦的训练，然而伴随现代竞技体育的强度越来越大，娇, 决心要找到救治此病的特效药物,
