The Changes in Great Natural Disasters Worldwide 1. 简述所给图表中的变化。 2. 说明引起变化的主要原因。 3. 分析这些变化对全球的影响。As can be seen from the graph, there have been rapid changes in the great natural disasters worldwide over the past period from 1960s to 1990s. To be concrete, there were only 16 terrible natural disasters, causing 300,000 deaths in 1960s while the ratios went up respectively to 131 and 1,100,000 in 1990s. The changes are disturbing, therefore, it is necessary for us to go into the whys and wherefores of them first.Some changes, such as those in earthquakes and volcanic eruptions, result from the movement of plates along the weaknesses in the earths crust, however, many others have much to do with mans activities. In the first place, mans mindless and excessive exploitation of natural resources has done a lasting damage to the ecosystem, only to invite more floods, landslides and mud-rock flows. The rare flood to which China was subjected in 1998 is typical of the evil seeds man had sowed for himself. In the second, in order to feed their more and larger families, people from all over the world have had to overwork their farming land as well as their grassland, which in turn has accelerated the desertification of the land on which they have been relying for existence. In the third, mans blind application of scientific findings has caused unfavorable and permanent changes in the global living environment. Among these changes are the depletion of ozone layer, the worsening of greenhouse effect, the recurrence of hurricanes and the extinction of more species.The list of causes could go on, but they are already enough to indicate that these changes are producing more and more negative effects on the world. They have not only made it impossible for the natural systems to recover their balance but also made it harder for man to ensure his better survival. If allowed to run its course, I am afraid, this trend will certainly bring more serious threats to all the living things on the Earth, mankind included. What Causes a Boom in Celebrating Foreign Festivals1. 近几年大学校园出现了一股过洋节热。2. 阐明导致该现象的原因。3. 分析该现象的社会影响。 Believe it or not, these years have witnessed a boom in celebrating foreign festivals on the Chinese campus. According to an official report/survey, young people, especially college students, are showing more and more interest in such festivals as Valentines Day, April Fools Day, Thanksgiving Day and Christmas Day. To get a better sense of the boom, it is necessary for us to find out its causes. A closer analysis of the phenomenon can find that three main factors are well worth our concern. In the first place, it is the product of students seeking after individuality and novelty, for which the college campus offers an ideal climate. (原因I) In the second, it is seen, among the students, as an ideal way of freeing themselves from stress for the time being, since most college students, only child of each family, are subjected to the unprecedented pressures from all sides though they enjoy the abundance of material wealth. (原因II) And above all, it is an inevitable result of more and more exchanges between Western and Eastern cultures. (原因III) While the Chinese watch their children thirst for the joy derived from foreign festivals, in fact, the Americans are discussing whether or not to list the Chinese Spring Festival among their official holidays.The effects of this change on our college life are positive. 10) On the one hand, it has created more chances for students to gain a better insight into other cultures. (分析I) On the other, it has enriched the college life, thus making the campus a more pleasant place to live on. (分析II) With more and more health and color added to the trend, I firmly believe, it will certainly bring more benefits to our campus life in the time to come.Views on Cloning 1. 有人认为克隆技术的应用利大于弊， 理由是 2. 也有人认为弊大于利， 3. 我的看法。Almost everyone would agree that the birth of Dolly, as the first clone of an adult animal, has opened a new way of seeing the creation of life for the world. But this agreement ceases to exist just when it comes to whether cloning will bring fortunes or misfortunes to human society.Many contend that the merits of cloning will outrun its demerits. They base their contention on the grounds that cloning is the most effective method of saving the rare wild lives from dying out. Besides, as they also point out, cloning can help provide better ways to treat some serious or deadly sicknesses, such as diabetes, and Parkinsons disease. Yet others react to the issue the other way around and hold that the opposite is just reasonable. From their angle of view, cloning will threaten the ecological balance by destroying the natural reproduction through the enjoyment of sexual love between the male and the female. And even worse, as they reveal, cloning will bring greater disasters to human society if it is used in creation of individuals with extreme genetic qualities, like terrorists, desperate scoundrels, and war manias. I stick to the opinion that anything new, including cloning, can bring human society fortunes or misfortunes, all depending on how it is exploited. On the one hand, it will be an inestimable blessing to the human world if it is applied to reproduction of best dairy cows or other choice domestic poultries. But on the other hand, it will form a big threat to human society once it is abused in copying those hostile toward humanity. In short, the solution to the problem is always within mans reach.How to Prevent a Terrible MarriageWith a sharp growth in the divorce rate, people become more and more concerned about how to avoid the potential risks of their marriages. To make it, some prefer to make premarital agreements before their wedding ceremonies while others still choose to maintain their marriages through their mutual trust. If I were asked to make a choice between the two, however, I would like to attach more weight to the latter than to the former.It is true that the marriage with a prenup (premarital agreement) does ensure a lot of benefits for the family, such as the protection of children from going hungry or the reasonable distribution of financial assets, once divorce is inevitable, but, compared with the marriage based on the mutual trust, it seems less attractive to me. To begin with, the marriage bound up with a prenup throws itself, from the very outset, into an ocean of family worries, thereby leaving little room for the spouses enjoyment of happiness their unity brings about. 6) By contrast, the marriage built on the mutual trust always nurtures itself in truth, romance and harmony, thus placing no limit on the spouses enjoyment of happiness derived from their intimate exchanges. Besides, the prenup-based marriage lays bare, in writing or in cold fact, the spouses desire or even greed for money, in which context there is no soil in their marriage for warmth to grow on.In contrast to that, the trust-based marriage always reminds the spouses of the truth that there is something more valuable than money in their marriage, in which case both the husband and the wife would tend to bring forth more love and attraction for each other. And the most striking difference between both lies in their emphases on the post-marriage life. The former couple will focus their life on the material or physical interests whereas the latter couple will center their life around the spiritual or ethical refinements. From the comparisons and contrasts above, anyone can conclude that my way of coping with the prospective problems of a marriage is more reasonable and acceptable. Therefore, I will refine my taste for marriage from today on so as to search the seas of people for the one who is resolved to share with me the affection and thought, comfort and hardship, joy and grief for life.What Enlightenment Can Be Gained from the Worlds Mysteries While we watch mans ability to tame the nature increase with each passing day, the human world is often at a loss what to do in the face of such challenges as the worlds mysteries. (议论的主题) The mystery of black holes, for example, has cast much doubt on what we have long been proud of or firmly convinced of. With a constant emergence of the unknown in the future, in fact, man will have to be faced with more and more of such challenges. If taken seriously, however, these challenges can shed new light on our ways of seeing and changing the world. For one thing, they can help build up mans curiosity for the world around him, as it is the nature of man to seek for the better explanation of something foreign to
