Dear Headmaster,
I'm writing to tell you about the discussion we've had on whether the school should organize a spring outing for the students.
Opinions on the question are pided as follows:70% of the students think that the school should organize the spring outing. They believe that the spring outing can make them enjoy the nature's beautiful scenery, which can broaden our vision and fill us with more knowledge. They also say that the air in the open fields is fresher. What's more, fresh air does a lot of good to our health.
On the other hand,30% don't like the idea of going out for a spring outing. In their opinions, time is very precious, so they have to grasp every minute to work hard at their lessons. Traveling costs a lot. In that case, it will add to their families' burden. Above all, no one can be sure of the safety of every student.
Yours truly
Li Hua
尊敬的校长，

对问题的看法有如下：70%的学生认为学校应该组织“春季郊游”。他们认为，春季郊游可以使他们享受大自然的美丽的风景，它可以扩大我们的视野，使我们更多的知识。他们还说，在空旷的.田野的空气很清新。更新鲜的空气对我们的健康有很大的健康。
另一方面，30%不喜欢外出郊游的想法。在他们的观点中，时间是非常宝贵的，所以他们要抓紧每一分的努力，在他们的课程中努力学习。旅游成本很多。在这种情况下，它会增加他们家庭的负担。首先，没有人能确保每个学生的安全。
你真正的
李华

5月21日上午，美丽的长沙万里无云，艳阳高照，在这样一个久违的好日子，虽然有点初夏的炎热，但我们来省城参观的石门县40多名师生代表，心情激动，兴致勃勃，一起来到这里，参观全省科技展。
我们来在湖南省科技馆门外，首先映如我们眼帘的是一个呈漩涡星系状、有着十分显著的楚艺术风格的巨大建筑，它气势恢弘，接待我们的解说员叔叔说，它是长沙最具特色的地标性建筑之一，是我省最大的科技宣传和普及场馆。包含了十个主题展厅：有“制造天地”、“材料空间”、“能源世界”、“信息港湾”、“地球家园”、“生命体验”、“数理启迪”、“太空探索”、“儿童科技乐园”和4D影院……
我们来不及听完介绍，就迫不及待地走进了临时展厅，啊，多漂亮啊，展现在我们面前的都非常罕见的动物标本，那麽多!看，这是“黑天鹅”。它漂亮，乌黑的`羽毛，红色的嘴巴，细长的脖子把它衬托得十分高傲，好像皇室中的公主。经过讲解，我明白了它来源于澳大利亚，是十分著名的珍禽。看，那是“鸳鸯”。以前，我一直认为鸳鸯是一只鸟，可这次一看，原来鸳鸯却是两只，它们出双入对，被人们视为爱情的象征，这两个小家伙小巧玲珑，但那葡萄般的大眼睛，像珍珠闪烁，美丽的羽毛像画中走出来似的……。在这个展厅，我们还看到了其他许多美丽的动物标本，学到了不少在课堂里学不到的知识。
参观完这个展厅，我们大家都明白，展出者是要告诉我们，要珍惜野生动物，保护生态平衡，呵护我们共同的家园!
一忽儿，我们就来到了科技馆A馆。一扇巨大的三湘院士墙矗立在我们面前，那上面介绍的都是湖南省取得重大成就的科学家，有两弹元勋周光召、杂交水稻之父袁隆平、纳米材料专家唐元洪等等。这些著名的科学家爷爷对国家做出的贡献，让同学们仰慕不已。是他们，爱国、勤学、报国!是这些包括全国的科学家们把自己的聪明才智贡献出来，才使我国的科技水平不断提高，我国的军事国防和经济发展水平才能走在世界的前列，我们的国家才无比强大，啊，我们生长在这样的祖国真幸福!
令我和我的同伴们流连忘返的还有“数理启迪”展厅。在这里面，有非常多的数学方面的知识展览，布展者把原本一个个枯躁无味数字定理变成一个个有趣的小展品。你看那个钉床，开始什么都没有，一按按钮，许多钉子就神奇地慢慢从小孔里钻出来，越长越高，之前，一个好奇的男同学勇敢地躺在上面，随着钉子的长出，那同学竟然没有丝毫疼痛的感觉。这使我们都非常有趣和惊奇。解说员叔叔告诉我们，“钉板”将人抬起的时候，虽然人体重达几十公斤，钉床承受压力较大，但在几千根钉子共同承受人体重力时，每根钉子承受的重量只有十几克，压力不大，所以钢钉就不会刺入人体。哦，原来这是一个数学原理啊，这种奇妙的感觉更加唤起我们对数学的的无限热爱。
我们又走进了太空展厅。那里面更加奇妙。那些耐人寻味的太空的知识、浩淼无垠的宇宙，更加激发了我们的好奇心。太空人的饮食以及住宿怎样?太空没有引力，任何东西为什么都是漂浮的?人在太空舱里为什么空中360度的旋转?等等等等，让我们这些小伙伴们叽叽喳喳起来。有些同学说：“宇航员真有趣，以后我也要当宇航员。”，有的同学说，“我要做个飞船制造家。”可是，又有谁知道，要想成为一个优秀的宇航员和航天专家，要饱偿多少酸甜苦辣?
不知不觉，参观就结束了。我们进行最后一个节目，到4D影院看电影。播放的电影是科普片《熊猫与古猿》，讲述了在远古时期熊猫和古猿是怎样存活的。有趣的是，4D电影让我们几乎身临其境。在惊险情节出现时，椅子会突然上下震动摇摆，有时候还会在你的脚跟后面刷几下;在小熊猫遇难时，我们的座位底下会有一个东西“蹿”过来“蹿”过去……这些效果使我心惊肉跳刺激好玩!哎呀，我胆子太小了点，真还需要锻炼呀!
马上就要离开省科技馆了，临别时接待的叔叔还送给我们每人一个书包，书包上标明着“湖南省科技馆赠”几个字，看到这个书包，我们真有点依依不舍起来。我想，这个书包，不紧让我永远记住了这个参观，更对我们是一个激励，更是一份希望，我们任重而道远。
参观展览返回的路上，同学们都还沉浸在激动之中。我想，科技真奇妙，科学家真伟大啊。我们一定要好好读书，学习前辈科学家“惟德学、惟才艺、不如人、当自砺”的信念与决心，一定要以科学家们为楷模，学好文化知识，接好科学技术班，长大了成为有用的人才，为国家的更加富强伟大做出我们的贡献。

《生物多样性公约》规定,遗传资源的利用应当遵循国家主权、知情同意、惠益分享的原则,并明确规定,专利制度应有助于实现保护遗传资源的目标。目前,一些国家已经通过专利 法律 制度保护遗传资源。为防止遗传资源流失专利法修改剑指“基因窃取”。
随着生物技术的发展,医药研发和动植物新品种开发过程中,越来越多的人不经生物资源来源地国家的同意,擅自利用他国生物资源进行医药开发,并申请专利,获得垄断利益。我国野生大豆遗传资源流失、“北京鸭”遗传资源流失,就是典型的案例。很多国人只知道“北京烤鸭”好吃,却不知道“北京烤鸭”是以

In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, I'm firmly convinced that too much tourists bring harm to the environment.
The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists don't have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.
It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.
Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past de
Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.
The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.
Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.
What' s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

8月1日，我们一行人乘坐春秋航班，来到了梦寐以求的海滨城市──青岛。那是一座依山傍水的美丽山城，那里有一望无际的海水浴场，有风景秀丽的崂山，还有精巧别致的红瓦绿树，真不愧为避暑度假的好地方。
我们先来到闻名的“海上名山”的崂山。我们的车行驶在崂山的盘山公路上，窗外群峰耸立，山海相接；山脚下海浪阵阵，波涛滚滚。我感到像到了人间仙境一样，令人心旷神怡。
登山了，我们沿着山路往上爬。不久，一排瀑布骤然出现在眼前，那瀑布就像巨龙飞腾，气势磅礴。这就是著名的“龙潭瀑布”，果真名不虚传，那宏伟的`气势就像“飞流直下三千尺”般壮丽。
第二天，我们来到了海滨浴场冲浪。青岛的海边美丽极了：天是一片蓝玉，海是一块翡翠，远望水天相连，蔚为壮观。我们踩在细软的沙滩上，奔向那向往已久的大海。
大海卷起一层层美丽的浪花，呼啸着向沙滩打来，一眨眼它又逃了回去，就像一群顽皮的孩子打闹着。这时，一个一米多高的大浪拥上来，我赶紧把身体背过去，一浪过去了，我就向前走几步。不一会儿，又一排大浪冲来，我赶紧往回跑……我们在海浪声中相互扑打嬉戏，绿海碧波留下了我们欢乐的笑声，那感觉正是爽极了。
青岛之旅给我留下了深刻的印象，要开学了，我多希望能有一个像去旅游那样快乐的新的开始啊！

At this time, a one meter high waves hold up, I quickly put the body back in the past, a wave of the past, I will walk a few steps forward. In a few moments, another row of waves rushed, and I ran back... We in the sound of the waves in the sea waves play each other furiously, leaving our laughter, the feeling is very good.
The trip to Qingdao left a deep impression on me. To start school, I wish I could have a new start like going to travel.
