高中英语作文介绍霍金 200字【一】
记得几年前，爸爸妈妈带我去看望外婆，外婆家门前有条小河，河水清凌凌的，闪着金光，缓缓地向前流着。河边，一群阿姨正欢笑着在洗衣服，一群孩子在河中游泳、嬉戏。我和妈妈挽起裤脚在河边捡鹅卵石，爸爸在旁边悠闲地垂钓。这安乐祥和的景象，现在我还记忆犹新。
然而，几年后的一天，当我再次看到那条河时，不禁吓了一跳。河水已经不清澈见底了，水是浑浊的，还夹杂着一些脏东西，光秃秃的河床上，水已快枯竭了，还散发着臭气。这些臭水是从哪里流出来的呢？我放眼望去，只见几家工厂正向天空喷射着烟雾，烟雾污染了白云，然后变成酸雨飘落下来，毒害大地；同时，工厂还不断地向河流排泄废水，将清清的河流变成了浑浊的毒水。煤是大自然几亿年蕴藏的太阳能，而在短短的几百年内得大量的开发和利用，大量的煤炭燃烧生成二氧化碳，造成了地球的温室效应。同时煤中数少量硫的燃烧生成二氧化硫气体，随雨水降到地面上，形成酸雨。酸雨毁坏了大量森林，成为生态系统的空中***手。
排水场的水还不断地向河里排放污水，就连河边的植物也死去了。这不就是垃圾场吗？原来干净的河水不再清洁，河水也不再流淌、空气不再清新。人们到底对这条相伴多年的老河抱着什么样的态度呢？是继续污染环境还是保护河流呢？是做破坏者还是做环保者呢？
由于水源的污染和地下水的超量开采，人类的淡水资源已经开始告急。由于森林的砍伐和过度开垦，放牧、水土流失和土地沙漠化问题日趋严重。由于地球的破坏，截至xx年已有2、3万种植物和1000多种脊椎动物绝灭，现在每小时就有1种生物从地球上消失。土地污染，人类乱砍树木，岩石下滑，洪水冲毁了房屋，淹没了庄稼；人们往河里乱丢垃圾，造成了水污染，到处可见随手扔掉的塑料口袋，形成白色污染。人们乱***动物，造成动物灭绝；人们乱摘花木，使我们失去了美丽。人类只有一个地球，我们生活在地球上，就要保护地球，保护我们的家园。

Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University

本来漂亮的地球，现在却是千疮百孔，到处都弥漫着难闻的气息，一个治好眼睛的小朋友看到这样的画面，忍不住向妈妈哭诉这不是我看到的地球妈妈今天在公交车上看到这则公益广告时，我的心里受到了震撼。
一个很期待得到光明的女孩却因为治好后看到美丽的地球变成这样，居然伤心不已，那么我们呢！不为地球如今这个现状感到痛心吗？难道我们还是一味的等待着地球的资源走向枯竭吗？
在现今，优于人们无穷无尽地开采资源，大自然遭到了严重的破坏。为了拯救奄奄一息的地球，世界各地都纷纷号召人们保护环境、珍惜自然，我也参与其中并乐在其中。
一个星期天，我在家里发现有许多废旧塑料、纸张各种各样，但它们都是相同的待遇送去垃圾场。我心想：这些物品都能循环时用，如果不能物尽其用真是太可惜了，何不做一个可分类的垃圾箱呢？对！说干就干！首先，像别的大城市的垃圾桶那样，做两个箱，非为可回收垃圾不可回收垃圾，涂上一些颜色后让人容易分辨，垃圾箱就完成了。我的杰作诞生，家人也慢慢接受了，还真给全家带来不少好处呢：我家离倒垃圾的垃圾场很远，又没有人上来收。
每次妈妈拿着大包小包的垃圾去倒是，汗流浃背，气喘吁吁，现在轻松多了，别人问妈妈为什么用这么少垃圾，当他们知道变废为宝的好处后，还要向我们学习呢。
此外，我觉得光是进行垃圾分类还不够，还要尽力地节约谁资源。
在家里，妈妈洗脸的刚想倒掉时，我阻止了她，并说水还可以循环使用，不要浪费；在学校，那个水龙头滴水，我一定把它拧紧。万物之泉，水，不得不珍惜。
如果全省、全国，乃至全世界，每人都节约一点，那将节约多少呀。我长大以后，一定研究环境，去保护我们那美丽的地球。

最近学校还在开展关于限塑令的调查和实施活动，增强大家的环保意识。学校还鼓励同学们学习环保知识，并介绍给认识和不认识的人。我班的志愿者活动也多次以保护环境，从我做起为主题展开活动，例如：到小壁林区进行义务植树，为城市增添一抹绿色；清理城市牛皮癣，为城市带来新的生机；打扫小区卫生，让小区焕然一新，使居民们生活在整洁的环境中
启动仪式结束之后，是异彩纷呈的文艺表演。令我印象最深的是诗朗诵《地球我的母亲》，朗诵者饱含深情地向我们诉说了炎黄子孙对地球母亲的种种劣行，以及炎黄子孙最后的觉醒和做出的深刻反思。最后，朗诵者呼吁我们要保护地球母亲，否则地球上最后一滴水会是人们的眼泪。
最吸引我们眼球的是，分四个展区集中展示的环保公益作品、环保科技作品、环保手工艺作品、环保时装秀。这些都是河北科技大学和我们四十中学志愿者亲手制作的环保展品、模型环保创意作品。这些参展的手工制品取材，全是塑料瓶、废板材等废旧物料他们丰富的想象力令我们叹服。首先吸引我的是无电动力车，设计者用牙膏盒和四个小轮胎制作成车，在尾部安装磁铁，手中的小棒也装有磁铁，利用同极相斥的原则，使车无需电池也能行驶。接下来的是大学生的塑料瓶系列展品，他们用一双双灵巧的手，将普通的瓶子变成一束束鲜花、一款款手镯、一个个储物盒最令人拍案叫绝的是用两个塑料瓶组成的沙漏，构思巧妙，制作精美，让人们赞不绝口。另一个大学生用一个个瓶盖做成了一套象棋，棋盘是由报纸做成的，真是即美观又经济环保。一位大姐姐还用废旧牛仔裤做成了背包，有许多人背起背包拍照留念。大嘴巴便签框是用废旧的开关贴组成的，将便签放进去就组成了一颗颗牙齿，栩栩如生，惟妙惟肖。各种各样的创意作品让我们开阔了眼界，增长了见识，激发了我们的奇思妙想，让我明白了科技与生活息息相关。其实，生活并不是缺少美，而是缺少一双善于美发现的眼睛。在生活中，我们要留心观察周围事物，做一个生活中的有心人，大胆的将一些废弃物和环保材料废物利用，也许你会收获到意想不到的效果。
据悉，这些参展的手工制品将在24个县市区进行巡展，让老百姓感受到科技带来的环保，会是可持续的环保，使市民在日常生活中保护我们的环境，爱护我们的城市。
活动的最后，我们观看了穹幕电影《深海绿洲》，那里有美丽的自然景观，各具特色的生物，它们和谐相处、其乐融融，影片向我们介绍了各种生物的习性，领略了独特的自然风光，认识了许多生物学家。穹幕电影《深海绿洲》让人有身临其境的感觉，随着情节的发展或平静或激动，让人们更深刻的体会到人与自然、人与动物应和谐相处，和它们成为朋友。
活动结束后，让我对本次活动的主题有了更深刻的认识，在实际生活当中，我们要将环保与科技紧密结合起来，为创造健康生活贡献自己的一份力量，争做一名我环保，我健康，我快乐的环保志愿者。
