根据2004年世界珊瑚礁状况报告，全球三分之二以上的珊瑚礁遭到严重破坏或处于进一步退化的险境，而气候变化依然是珊瑚礁所面临的最大的长期威胁。8日，世界自然基金会中国分会公布了一份气候变化公约第十次缔约方会议上发布的报告。
该报告汇总了来自96个国家的240位专家的研究结果。报告指出，全球20％的珊瑚礁已经遭到无法逆转的\'严重破坏，而另外50％的珊瑚礁也接近崩溃边缘。如果不采取行动的话，全球变暖将导致全球珊瑚礁的最终死亡。气候变化正在导致海水变暖，而这会造成海水酸度增加。科学家们预测，像发生在1998年的波及全球16％的大面积珊瑚礁被漂白的事件，在未来50年里会时常发生。
当海水变热时，珊瑚会释放体内的海藻，而这就导致珊瑚礁被漂白，从而导致珊瑚礁死亡或者退化。同样，溶解在海水里的二氧化碳的浓度的增加将导致海水酸度增加，而这将减缓石灰化———即珊瑚礁形成的速度。有关专家指出，到本世纪中叶，二氧化碳的排放量可能会达到目前的两倍，珊瑚礁的石灰化程度可能要降低40％。
在第十次缔约方会议上，世界自然基金会呼吁各国政府使全球平均气温控制与工业前水平相比增长幅度不超过2OC。科学家们指出，如果不能将气候变化控制在这个限度内的话，将会导致极端气候灾害现象的增加，并将导致更多物种栖息地的损失和引发更多物种的灭绝。
世界自然基金会全球海洋项目总监西蒙克利普博士表示：要想保护珊瑚礁，各国政府不仅需要减少二氧化碳排放量，还需要建立海洋保护区，以保证珊瑚不受到任何形式的威胁。珊瑚礁每年的生态服务价值超过300亿美元，我们不能因为气候变化或其他原因而承受如此大的社会和经济价值的损失。2004年世界珊瑚礁状况报告显示，近期得到保护的珊瑚礁的状况正在好转，这给世界各地的珊瑚礁的未来带来些许希望。
珊瑚礁主要分布在南、北纬度30°之间的热带浅海环境中，总面积达1000万平方公里，其中以太平洋的中部和西部、澳大利亚的东北沿岸、印度洋的西部及大西洋的西部百慕大至巴西一带的海区为最多。

the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.

下面谈谈学习毅力的.问题。如果你有坚强的毅力，那么世界上就没有什么难事。学英语关键是能够持之以恒。
在学习过程中，你应该制订一个计划，一天记住几个单词，一天记住一两个句型。你不要小看“持之以恒”的力量。举个例子：
如果你一天背5个单词一年就是1825个单词，相当于初中三年再加高中一年零两个月的词汇量。如果你坚持两年你就能住3650个单词，相当于中学六年包括本科两年的词汇量。
在制订计划时要遵循以下几项原则:
1、计划要切实可行，不要好高务远。上面的例子已经说明，只要你能坚持天天学习，英语一定能学好。
2、要有坚强的毅力，每天都学习，不因为某些事而耽误了学习。如果哪天的工作没有完成，第二天一定要补上。连续不学习的时间不要超过两天。
3、要有一个帐本，哪天学会了哪几个单词，哪几个句型一定记录在案。
4、为了把单词、句型真正学到手，第二天一定要复习第一天的，第三天一定要复习第二天和第一天的内容。
5、所选择的课本可以是一套或两套，千万别太多。实际学英语的书没有什么好坏之分，只要你能按照一套或两

Dear Mr. President,
My name is Li Ming. I am a sophomore of the law school. As the school year is drawing to a close, I venture to write a letter to you about the canteen service on campus which has given rise to much complaint among students.
The focus of the complaint is the poor quality of the food. The rice is just like bullets and the buns are like hand grenades. They are too hard for us to chew. And the vegetables are so overcooked as to lose their nutrients. The fish and meat are not given full measure. The only thing we are satisfied with is the free soup. However, the price of the food is surprisingly high. If we have 3 meals all in the canteen, at least twelve yuan is gone to keep our body and soul together. As a result, many of us go out to have meals.
Honestly speaking, the dining environment has been improved, with the wall painted and some Chinese calligraphy works posted up. But there are only two canteens on the campus. As the number of students is ever increasing, there is not enough space and seats to allow us to have our meals there. The attitude of the service staff to the students is not hospitable at all.
All in all, there is still much room for improvement as far as the canteen service is concerned. I hope we will not suffer for another two years.
Best regards.
Sincerely Yours
Li Ming

一个秋高气爽的早晨，我和妈妈一起去锻炼。
我们来到了锻炼的体育器材场，我们就开始锻炼了。我先锻炼了一个有点像自行车一样的体育器材，它是锻炼我的手臂的。我就按照了它的说明来做，先把手放在像自行车的车把上，然后，再用吃奶的力气往下一拉，又接着再往上一推，就这样连续做。妈妈锻炼的体育器材像一张床，人躺在它的上面。然后，用手抱住头，脚就勾住下面的\'横杆，使劲使自己的头再抬起来，就这样反复的做。原来它做的是仰卧起坐呀。我们又锻炼了一会，那个时候我已经是气喘吁吁了。
今天，虽然我们锻炼的很累，但是我们健康了我们的身体，而且这样还可以预防感冒呢！
