Air pollution is one of the major problems of the modern world

1、Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of whi

2、ch remain in the air, causing air pollution. Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are be

3、ing modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to preven

4、t and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution. Pollution is becoming more and more serious all over the world. As is shown in the cartoon， two cars are giving off waste g

5、as and three people are trying to avoid breathing in the poisonous gas by masking their face with their hands. The poisonous gas sent off by factories， domestic appliances and automobiles has made the air unhealthy for people to breathe.2.意义阐述段 There is no denying that automobiles are indications of

6、 civilization， progreand development; neverthele， automobiles cause the serious problem of air pollution. Scientists have warned that unleeffective measures are taken， the problem of pollution will eventually get out of hand. Actually， people are showing a real concern over the problem. For example，

7、 there is an increasingly loud voice from the public for firm action against pollution from automobiles.3建议措施段Indeed， the earth is our home and we have the duty to take care of it for ourselves and for our descendants. In my opinion， we should work out concrete solutions to the problem of pollution

8、from poisonous gas given off by automobiles. For example， the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Only in this way can we really solve the problem of air pollution caused by automobiles.The cartoon presents the Earth wit

9、h a personified human face that seems quite unhappy. A examination of the picture immediately reveals that the source of its mood is the air pollution resulting from a huge number of automobiles spread around its surf-ace.The cartoon, no doubt, aims at alarming humans of the heavy load we have exert

10、ed on Earth by our insatiable production and usage of automobiles. However, the majority of people merely indulge in the celebration of the convenience brought by cars, while forgetting or simply neglecting their harmful impact on the atmosphere. Admittedly, there are various factors contributing to

11、 the current worldwide air pollution, but it is undeniable that the exhaust from automobiles is categorized as one of the major elements.I would like to make the following proposals to solve this problem: firstly, we should apply the most cutting-edge technologies in order to adopt new forms of ener

12、gy as substitutes for fossil fuels. It should also be guaranteed that the clean energy be inexpensive so that it can be widely accepted. Besides, there should be attempts to develop possible transportation means, so that citizens can be diverted from dependence on cars. In short, it is humans' r

13、esponsibility to resume clean air for Earth.The drawing portrays a tragic scene in which a rabbit is telling a story to her son, with numerous fresh tree stumps surrounding them. It seems that the tree stumps are lamenting the loss of their paradise as well.The picture aims at assailing a serious en

14、vironmental problemdeforestation, for which several factors are responsible. In the first place, no one can ignore the fact that wood is an indispensable raw material for industrial production and daily life. In the second place, the expanding human population requires more living space, and forests

15、 are always the first choice humans decide to sacrifice. As a result, forests have experienced, and are experiencing fatal destruction worldwide.Currently, people in increasing numbers come to realize the forests fundamental role in sustaining ecological balance, and their damage will result in irre

16、versible harm to the worlds environment. Therefore, urgent and effective measures should be implemented so as to prevent deforestation. For instance, there are already some steps that have proved useful, say, the establishment of reserves of natural lands, the creation of substitutes of wooden produ

17、cts. The preservation and restoration of forests is a complex project that calls for more concern from the human society. (203 words)这幅图描绘了一个悲剧的场景：森林中，一只兔子正向幼兔讲述过去的事情，在它们周围到处都是刚被砍掉的大树留下的树桩，而且这些树桩仿佛也在悲叹失去的生活天堂。这幅漫画的目的在于质问一个严重的森林环境破坏问题，这其中有许多原因。首先，没有人可以忽略这一事实，木材是工业生产和人们生活中不可或缺的一种原材料;其次，不断扩张的人口规模需要更多的生

18、存空间，而森林往往是人类需求的第一个选择。因此，在全世界范围内，森林正在经历致命性的毁灭。现在，越来越多的人开始意识到森林对于保持生态平衡所起的重要作用，而对森林的破坏将会对全球环境造成不可逆转的影响。因此，我们必须采取紧急和有效的措施来制止这一砍伐森林的趋势。例如，我们已经有一些被证明为有效的措施，如建立自然环境保护区，发明替代木材的产品等。另外，森林的保护和恢复是一项复杂的系统工程，需要全社会对环保问题的共同和全面的关注。DeforestationAs time goes , there are more and more world problems about nature and d

19、evelopment. I think deforestation is the most serious environmental problem that the earth has to face.With more and more trees cut down, many kinds of birds or animals have no homes and become extinct. Just a few years later, we will no longer be able to see so many lovely and beautiful creatures w

20、hich once exist. With more and more trees cut down, lots of good land become deserts. Then the soil will be washed away more easily ,which will eventually lead to floods and draughts .remember the Big Flood that broke out in 1998? Many people become homeless and I will never forget the sad and eager

21、 eyes of hundreds of children .But what we should realize is that it is we human beings that has strengthened the power of the flood, for weve cut down so many trees near the Changjiang River. The disaster is just a response from nature, as well as a great pain to us.With more and more trees cut dow

22、n, the power of the surface of the earth to control the climate is being reduced greatly. The earths surface temperature is rising little by little and finally cities along the seaside will be greatly affected.In fact, desertification, global warming and other big problems are all the results of deforestation.But many of us have not yet been clear enough about the importance of the prob
