思考一切英文精选20篇

For most girls, I believe they must have read the story about Cinderella. The story tells about a beautiful and kind girl named Cinderella, her mother dies when she is very small, so his father marries another lady who has two daughters. When the father dies, Cinderella is bulled by his step-mother and step-sisters, but she keeps nice to them. One day, Cinderella meets a prince and when she joins the party, she has to run away before midnight. The prince finally finds her by his missing glass shoe. Finally, Cinderella lives a happy life and her step-mother and step-sisters are punished. The story tells people that if we are kind to others, we will have the good return.

对于大部分女孩子来说，我相信他们肯定有看过关于《灰姑娘》的故事。故事讲述了一个叫灰姑娘，美丽又善良的女孩。她的妈妈在她很小的时候就去世了，因此他的爸爸和一个有着两个女儿的女人结婚。当爸爸过世后，灰姑娘被她的继母和两个姐姐欺负，但是她一直对她们很好。有一天，灰姑娘在参加舞会的时候遇到了一个王子，但是她在午夜前就逃跑了。王子最终通过水晶鞋找到了她。最终，灰姑娘过上了幸福的生活，她的继母和姐姐们也受到了惩罚。这个故事告诉人们如果我们善待别人，就会有好的回报。

我是一只蜗牛，喜欢独自在墙壁上运用智慧来思考，思考着世间的万物！

在人类眼中我们是弱者，但我们不羡慕豹的狂奔和鹰的翱翔，因为我知道一切形体的敏捷，都以思维迟钝为代价。我在宁静中眺望，在眺望中思索，在思索中穷其一生。我无足无翅，不堪一击。虽然蛙有健壮的双腿，却被无腿的蛇所吞；蛾有轻盈的双翅，却被无翅的蜘蛛所捕。我想这应该是一个不朽的嘲讽吧。

我不羡慕天鹅的纯洁和黄鹂的婉转，因为那些生得秀巧的动物一般都被人圈养，被人娱乐，供人驱使，失去了自由。我虽没有强健的体魄，但却有深邃的思想；没有多彩的生活，但却有甜蜜的蛰居；没有伟大的事业，却有过人的哲学。我们讲究的是智慧的深度和思维的广度。

我们驼着笨重的“家”慢慢得在历史长河中行走了几千年，物竞天择，优生劣汰，孰不知曾经称霸地球的恐龙，只留下一堆堆骨骼化石，供人参观。时间的筛选证明了我们是强者。

“海不择细流，则成其大，山不择微沙，故成其高”，而我不择黑暗与潮湿，故能在这纷繁杂乱，争夺无休的世界里繁衍生长，享有清闲。

茫茫宇宙上宽下厚，浊浊世间，前拥后挤，碌碌人海，人才辈出。强者以其力胜人，智者以其巧胜人，丐者以其怜胜人。蜗牛退居一隅，回归自然，无知无觉，不参加那毫无意义的追逐狂奔。

老子不愿陈设于案头，而愿曳尾于浊泥；陶潜不愿羁绊于尘网，而愿采菊于东篱；我不愿喧哗与一时，而愿宁静以至远。只借一片枯叶，沉睡与思考。

with the increase of chinas population, housing problems are becoming more

and more apparent. many people complain that their houses are too small to live

in, and we can see in some pool families, six or seven family members live in

one room. therefore, the living conditions cant meet their-needs.

there are many difficulties in solving housing problems. first, its

impossible to put all the space into building houses. secondly, the population

of china increases year by year and with the improvement of our living standard,

we need more room to relax ourselves in.

various solutions have been put forward. i think the most important and

efficient way is to control the population. also, we can build more high

buildings to provide more living space. i believe the housing problems will be

solved.

dear chen lin and li hua,

i’ve just been out of hospital for a couple of days. right now ，i am really fine, but without your support, i wouldn’t have got better so soon.

you know, the traffic accident gave me a very hard blow, both physically and mentally. in the first two weeks after my injury, i almost lost my confidence in my future life. it is the doctors’and your encouragement that rendered me much strength and determination。

anyway, i learned a lot from this unfortunate accident. i’d neverrealize how important your friendship was to me. i can’t say anymore to show my gratitude for your taking turns keeping me company,and getting me through the blue time.

next saturday, my mother would give a recovery party to thank myfriends. i really want to see you there. so, 7 o’clock at my place,ok?

your truly,

li ming

生活中，我们常常会抱怨某某人做事糟糕，做得不对或不理想，可事实上有多少人将自己放在当事人的角度上思考过呢?如果我们设身处地地思考一下，就会减少许多误解。

前不久，我们几个班干部提出?教室后面的黑板报不要总是由固定的几位同学来办，应该大家一起想点子，没准可以想出更富有创意的设计。现在机会来了，又要办新的黑板报和艺术橱窗了，这次就靠我们几个班干部来“大显身手”一番了。

星期六上午，我们约好来到教室，开始设计黑板报。可是两个小时快过去了，黑板上仍旧一片黑，没有一丁点儿色彩。在一番挖空心思之后，我们终于设计出了报头、边框。可是画完以后大家才发现，报头一点也不美观，线条又很粗糙，板块之间有的地方密集，有的地方稀疏，很不协调。大家不得不又加工、修改甚至重新再来。苦干了一上午，总算是基本完成了。

下午我们又设计起了艺术橱窗，整个下午只完成了三分之一。然而第二天下午再次来到学校时，我们才发现前一天的作品很不美观，于是又重新开始布置。花了整整一天半的时间，我们才将一块黑板，两块橱窗全部布置完了。

从前，我总认为别人办的黑板报并不漂亮，橱窗的布置也不够精彩，可现在自己实践之后才体会到：原来有些事看着十分容易，可实际做起来并不那么容易。我只评论别人干得不怎么样，可自己呢?自己不也同样办不好吗?因此我们不管遇到什么事，都应该学会换位思考。

生活中，我们往往喜欢充当评委的角色，经常评论别人的不足，似乎把自己看得很伟大。当真正的任务落在我们头上时，我们却又感到无从下手。好不容易理出了些许头绪，就忙碌了起来，到头来即使不差劲也不比别人强。

因此换位思考往往能够使人正确认识事物，也可以减少对别人的抱怨，使得彼此之间的关系更为融洽。

In last years eleven holiday, our family went to Lanzhou and Xining to travel. That afternoon, Dad suddenly told us to travel, we promised.

Our first goal is Lanzhou, and we dont know the road at high speed. It was dark. We went all the way in the mountain road. Finally, we arrived in Lanzhou. After dinner, we began to find hotels, went to many hotels, but they were all overcrowded. We searched and searched, and finally found a guest house. The second day, we went to Wuquanshan, many people drove up to the door of my difficult to calm the mood. Bought a ticket in the first eye to is Huo statue around the past is a temple, called Confucian Temple.

Where we took a photo and went out to the mountain, we go on a mountain is wuquanshan. Because of the rain, many roads were mud, a lot of mud was stained on the shoes, and then I saw the attic. It seems the Huo, we went down the steps down the road I inadvertently looked down is a small squirrel on the tree to jump for a while and then disappeared. Down the hill, we did not stop at Xining again. In the evening, we came to Xining in Qinghai province. We found the hotel, lived and slept for a night to relieve the fatigue of the day. In the morning, we were ready to go to Qinghai, and we started out after breakfast. On the way we came to a place and had a strong wind. I came out and shook and went to sleep in the car. When I woke up to the edge of the lake in Qinghai, I stretched out, and I knew that the ticket for Qinghai Lake was 50 yuan.

I see mom and dads eyes know is not to buy a ticket, we had to walk along the road and found no fence, there is one family living they took us to the lake, took a photo, listen to them before the Qinghai Lake is great, but now more and more small, this is not the results of the protection ring. We went to a rape place, the smell of the faint fragrance, has gone down in the west of the west, will our hearts call back. Passing by, we found a bucket of honey and a sweet taste! We slept early in the evening, because we were going home tomorrow.

I dont want to go back! Ill come again if theres a chance!

这值得思考。

楼下的钢化玻璃有两处碎裂的地方一处在停车位后一处在离人行道较远的绿化带后，紧邻一户人家的窗户边。这两处的碎玻璃上都贴上了温馨提示停车位后的碎玻璃上贴标语，不难理解。因为人员经过比较频繁，自然也就十分值得被注意。可绿化带后的碎玻璃贴上就有点奇怪，人要穿过长长的一层绿化带才能到达那里，为什么还要贴上呢？后来经过我的观察，可能有三种原因，一是修剪清理绿化带的工人，他们可能在向绿化带内部清理时，不小心触碰碎玻璃。二是空调的装修维护工人，碎玻璃离一户人家的放置空调外机的地方很近，在工人维修时，也很有可能触碰到。三是碎玻璃下方是一个停车通道，提醒人们能看到此处，防止玻璃碎裂从上面落下，划伤砸伤居民，防微杜渐。可见每一处可能带来隐患的细枝末节都值得我们思考。

随着共享单车的不断发展，大街小巷到处可见到它们的踪影。可能由于自行车费力气，于是共享电动车又横空出世。由于不需要费什么力气，很多单车上都直接坐上了两个人，虽然根据法律共享电动车是可以再带一名儿童的，可很多年轻人也都两人同坐一辆电动车，共享电动车本身重量较轻，承重能力不强。两名成年人使得电动车行驶的安全隐患加重。而且在行驶过程中看起来十分的臃肿，变扭，影响市容市貌。共享单车得以能多载一个人主要是靠后面那块大电瓶。当然我觉得这也是无奈之举，虽然本意并不是想让车能坐两个人，可是电动车需要长时间的续航能力。而且共享电动车也是为了能够盈利，也不希望两人同坐一辆电动车。所以对于这种现象，也只能依靠人们的自觉和宣传教导。

可见每一处可能带来隐患的细枝末节都值得我们思考。

Dear Santa Claus,

See the letter please!

Santa, I dont know what you really look like, but Ive seen a lot of

pictures of you. Every year on December 25, you bring us Christmas presents.

Legend has it that you will ride in a reindeer wagon full of presents and

pull a sleigh to deliver presents to each child. I also know that you will wear

Christmas clothes, wearing a red Santa hat, quietly put gifts into the

childrens Christmas socks.

tales.

Every Year at Christmas, we can make one wish come true. This Christmas, I

to do things and do homework very slowly. Santa, can you help me break this bad

habit? If I could get rid of it, mom wouldnt have to watch me do my homework!

Then mother will be very happy.

You are a great Santa Claus, you will help every child to achieve the

wishes. So, can you give me my wish, too?

Zhu: happy every day! Health and longevity!

亲爱的圣诞老人：

见信悦!

圣诞老人，虽然我不知道真实的你长什么样，但是我在很多照片上看过你的样子。每年的十二月二十五日，你都会给我们送来圣诞礼物。

传说，你会坐着满载礼物的驯鹿车，拉着雪橇，为每位小朋友送礼物。我还知道，你会穿着圣诞服，戴着红色的圣诞帽，悄悄地把礼物放进小朋友的圣诞袜子里。

所以每个小朋友都非常喜欢过圣诞节。这是一个充满了童话色彩的节日。

每年的圣诞节，我们都可以实现自己的一个愿望。今年的圣诞节，我有一个愿望。圣诞老人，你可以帮我实现吗?我身上有一个坏习惯，那就是做事写作业都很慢。圣诞老人，你可以帮助我把这个坏习惯改掉吗?如果我可以改掉的话，妈妈不用再盯着我做作业啦!那样一来，妈妈会很开心的。

你是一个很了不起的圣诞老人，你会帮每个小朋友实现愿望。所以，你也可以帮我实现我的愿望吗?

祝：每天快快乐乐!健康长寿!

我躺在床上，辗转反侧难以入眠，打开mp4，聆听着那首我们心爱的歌曲，心有些痛，鼻子酸酸的，眼泪随着脸颊一直滴落到枕边，用手触摸着那歌，手心暖暖的，好像在牵着你的手，在杉树林走过那个桥洞，脑海中不断浮现你的欢笑的映像，而我的泪像泉水一样不间断地涌流着……

萧瑟的风一直在吹，试图去抓住你，可是那时的我还小，眼睁挣地望着你静静地飞走，小时在遥远的天际。

还记得你那天静静地躺在血泊里，你的脸被鲜血染红，你冷吗？你害怕吗？我只是呆呆的望着你，想要将你扶起，可我害怕，害怕你的灵魂，你那红透了的躯体。我尖叫着，像个发疯的牛狂奔出去，我无法让自己平静下来，不知为什么，那一刻我居然哭不出来，我第一次望着自己的亲人永远的离开我，我坐到了小河边，河里结了冰，我看着冰块，冰层间不断地浮现你的影子，你在冲我笑。我想要和你一起笑，可是那一刻我才意识到你不留痕迹的永永远远的离开了我，剩下我一个人在这个孤寂的世界里独自行走，我嚎啕大哭，一滴两滴三滴……

夜里的风使人不寒而栗，没有人行走，只有我，像个行尸走肉地托着沉重的步伐，我不知道该怎么办？第一次感到这么无助，我望着那车那人堵住那门，我想去却又不敢去，伫立在门外，只听见风在呼啸，嘈杂的声音像被过滤了一样，那时星星都睡了，漆黑的夜笼罩了所有的光明，我蜷缩在床上，不断浮现，一幕一幕……

你走了，走的静悄悄，像阵风吹走了就再也回不来，我不断地向你招手，呼唤你，你只是离开，你忘了吗？你答应过我，我们一起穿上嫁衣步入礼堂，与心爱的人去爱琴海感受柏拉图的永恒，你说我们是永远的朋友，你说过日本的樱花美得让人心醉，你说你要带我走过地球一圈，你都忘了，我在梦里不断地质问你，你沉默，我看不见你的脸，我想尽力抱着你，可却失望的知道那只是你的魂。

我知道你走了，再也回不来了，我会记得，我会好好地活着，完成你的心愿，看柏拉图的永恒，烂漫樱花。

走了，记得我，来生我们一起走完人生。

静静地听着那首歌，失去了才知道珍惜，慢慢走入有你编织的梦境。

希望大家不要金介意我的语言的不足，这只是我的亲身经历与感受，望谅解！

“公元3017年，人工智能开始大肆反抗人类，不听从命令，还想将人类赶尽杀绝，称霸地球。然而他们放走了制造他们的科学家们，给人类留下了一条生路，人类收回属于自己的权利之路启程了……”

面对电影荧幕中如此骇人听闻但却极能吸引人们眼球的故事。邻座的她，打了一个哈欠，轻轻道：“有些事机器比我们做得更好，但那不意味着机器比我们更聪明。而且人工智能没有感情，他们既不会爱，也不会恨……”他默默听着，感受着邻座的理科女如计算机一样严谨的思维方式。可他没想这么多，继续沉浸于主人公一波三折的冒险之中。

电影结束了，他走在街上，早晨的小雨已经停了，空气中还带着桂花的芳香，他深吸了一口气，将芳香和清新的空气都装进体内，神清气爽地走进图书馆，走向他最喜爱的位置，可现在那位置对面坐着一个人，笔记本电脑的线缠绕在一起，挂在插座上挡住了他的去路，他把她绕成一个毛线团的线解开，放在地上并在她对面落座。

正巧，窗外一束阳光洒在桌上。她嫌弃地挪出那块光亮区域，他想，有什么人竟不愿被从十万八千里的远方还不惜任何代价赶到你身边的阳光所照耀，抬眼一看，竟然正是刚才电影院邻座的“计算机”，看看这束阳光，再看看窗外，刚下过雨的天气，雨露从桂花花朵上划过的情景，美得让人陶醉，此情此景不忍让人感叹道，我们难道没有“想念北平却什么也说不出”的思念吗？难道我们没有“身边处处是围城”的感慨吗？难道我们没有《边城》小桥流水下的纯真吗？

她惊讶地看着他，旁边的老爷爷摘下老花镜，也望着他。

他竟在大庭广众之下将刚才脑中所想一字一句地说了出来，咳嗽两声掩饰尴尬，他邀请她出去走走。她没有拒绝，边走边小声说道：“空气湿润，又是传染病高发时节，其实不宜出门。”他有些汗颜，但随即被路边一个纸箱吸引，俯身一看，是一只弃猫。“这种猫不是生病就是长相不好看被人丢弃，刚才还下过雨，再感冒，必死无疑。”他再次被她“计算机”一样的思维打败，他不理会她的话，抱起猫就走。

“等等。”她上前用一块方巾裹住小猫，粗略地检查了一下，并无外伤，“你说我似计算机一样刻板，现在计算机死机了，不能理解你的所作所为，所以计算机只好模仿你的举动，把这可怜的小家伙带回家，等它无大碍后再放生。”“放生？”“不对吗？”“正常人会把它养着。”“好！”

他思绪回到早晨看过的电影，依稀记得电影中，存活的人类反省并修复了人工智能的漏洞。人类和人工智能再次其乐融融地生活在同一个星球上。同时库克的名言跃入眼帘“我不担心人工智能让计算机像人类一样思考问题我更担心的是人类像计算机那样思考问题，摒弃价值观和同情心，罔顾后果。”

“’计算机’的思维还是可以改变的呢。”

他和她，抱着猫，并肩走远……

怀疑是可贵的，敢于质疑的精神在我们当今社会是十分重要的。有一句话是这样说的：“不要迷信书本，也不要迷信权威。”书本、权威是指当今社会已有的，被大多数人认可的知识，但却不一定代表真理，因此，我们就要具备敢于质疑的精神，也要拥有独立思考的能力。

记得那是去年六年级上的一堂数学课。张老师拿着数学书在给我们讲一个知识点：1——……=0，也可以把一整条段看成单位“1”，第一次取走，第二次取走，接着是…………，这一条线段就一定会被完全取走，我对这个知识点不禁感到奇怪。

我记得曾经看到过这样一句话：“天下无物，日取其半，万事不竭。”意思是这样的：一件东西，每天取走它的一半，永远也取不完。因为数是无限的，所以这句话一定正确。可是书本上明明却与这句话相反，谁敢怀疑课本呢？我沉思许久，毫不犹豫地举起手，向老师说明了这一条观点，许多同学听了知识后，也纷纷举手，同意我的观点。老师听了，也陷入了思考，终于，认同了我们的这条观点。

这件事在千千万万这样的事例中，连一粒尘埃也算不上。可是，如果没有这种精神，也许就不会有今天的“两个铁球同时着地”、“日心说”……所以，我们平时生活中质疑看似正确的观点，这样会使我们收获很多。

The thankful great universe provides the environment of existence for us

and give us sunlight, air, water and everything in keeping with us existence of

space, bring storm to let us accept to toughen for us, bring to us mysterious

let us look for. The thankful parents give us the life, make us feel the

hardships and pain and sufferings of the human life! The thankful teacher works

with diligence and without fatigue everyday of teach, give us knowledge ability,

and put on the wing which flies toward the ideal for us. The thankful classmate

and friend grow up with us and let us no longer stand alone in the itinerary of

Tomorrow is March 8th. It is Womens Day, so I want to give my mother a surprise. First I am going to the supermarket and buy something , such as vegetables , fruits and some beautiful flowers. Then I will come back home to clean the house and do some cooking. When Mum comes back from work, she will be really excited. She will say that I am a nice boy and have grown up. I will be happy, too. I think Ill help my mother more in the future.

放学了，骑着自行车急急脚地踏着、踩着。在心中，永远最舒适的地方就是自己的家了。妈妈永远都是“惜电如金”，在乌暗的厨房里奔波，而一切的劳碌却只是为了炒一道合我心意的菜……想到这，我不得不加快速度了。

忽然，一个转角，让我重重的摔倒，多少次与这角落相遇，继而摩擦，最後相背而道。在这角落也沾满了我的味道，我跌撞过的痕迹……拍拍衣服後又继续我的归家旅程。

望着这片片熟悉熟悉的田园，心情也随之兴奋。黄昏时段的乡村是个忙碌的时分，田里的农民加快浇菜，各家门前都可看见熟悉的身影……

但当我踩进最熟悉的方向是，床前的收音机打破了一切的美好。我用尽所有力气拍停它，甚至整个房子都听到我的手发出疼痛的叫声。

睡眼惺忪的我拖着鞋子知恩那个摸着墙壁走进了厨房，没有一点饭香味，打开冰箱一看，却塞满了大小不一的罐头。验伤冰箱後我倒了杯水，坐在冷冰冰的沙发上。这一天，我又成为宅女了。手上拿着最喜欢看的肥皂剧光碟，却没有想放进播放器的慾望。走进书房，摆放着经典的爱情小说，但今天它们却没有一点吸引力。

还是选择躺在床上。很舒服，却再也睡不着，回不去那个熟悉的地方了。窗外的眼光明明是如此的温和，却能把我眼睛射的刺痛。从窗外望出去，是一幢幢毫无美感的高楼，街上的人们，是各顾各的，在一张张朦胧的脸上，找不到某些熟悉的皱纹。

房间每个角落也镶上那刻的快乐，但是那张真挚的笑容，早已淹没在这个城市里了。

没有了晨早阿姨的拍门声，没有了一个个该死的转角，没有了爸爸最爱惜的花园，再也不需要跑上跑下的开门，也不需要小心翼翼的踩自行车，亦不需要早晚定时浇花淋水了。可是为什麽活得比以前更匆匆了呢？

眼前的一起变得模糊了，看不见人脸，看不见厨房，看不见街上的一切了……

I got up early this morning and had breakfast quickly. Then my mother and I

took the bus to my grandmother`s home. My grandmother was glad to see me again.

She gave me candies and a cup of milk. She was really kind to me. At noon, we

had lunch, There were lofts of people. After that, I talked with my grandmother.

She laughed again an d again. Then I played with my brother and my little

sister. Finally , I said "see you " to each other.

今天早晨我起床很早,吃过早餐很快。然后,我妈妈和我搭公共汽车去外婆家。我的祖母是很高兴再见到我。她给我的糖果和一杯牛奶。她真的很仁慈地对待我。中午,我们吃午饭,有阁楼的人。之后,我跟我的祖母。她笑了一遍又一遍。然后我与我的兄弟和我的小妹妹。最后,我们互相道别。

In Haimen there is a park. It’s a big and beautiful park. It has two gates. They are the North Gate and the West Gate. Many people park their bikes in front of the gates.

There is a shop at the North Gate. When you go into the park through the North Gate, you will find a large square on your right and you will see lots of trees and flowers around you. In the west of the park, there is a playground.

Sometimes some children fly kites on it and some people sit on the grass and chat. In the middle of the park, there is a lake. There are many boats on it. There is a hill in the east of the park.

The park is very beautiful. I love it very much. Will you come to visit it some day?

There are many rules in our school.

From Monday to Friday，we have to get to school before 7：00 in the morning.

We must wear school uniforms，and I think it is good for us because uniforms can

make us look smart. We must listen to our teachers carefully in class and finish

our homework after school. We are not allowed to use mobile phones in class. I

think the rules are very strict but useful，and we should follow them. However，we

have so much homework that we have little free time to do what we love to

do.

In my opinion，we should have more free time to take part in all kinds of

activities and improve our abilities.

在七年级“数学报”第一期上，刊登了这样一道怪题：

以前，美国举行了一次“全美数学能力测验”，有83万中学生参加，其中有这样一道题：有个三棱锥和一个正四棱锥，他们的棱长都相得，问他们重叠一个侧面后，还露出几个面？标准答案是七个面，因为两锥分开时有4 5=9（个）面。当他重叠一个面后，有两个面被遮住了，所以标答案是七个面。可是一位十七岁的中学生丹尼尔的回答却是五个面，阅卷者当然判他错。丹尼尔为了证明自己的结论是对的，回家后做了个模型，当他把这个模型交给老师时，老师不得不承认丹尼尔的结论也是对的。

从上面似乎可以得知，有两个标准答案：一是原来的标准答案七个。二是丹尼尔的答案五个。我回家也做了两个模型，一推演，发现只要是在三棱锥和四棱锥棱长相等的特殊情况下，三棱准和四棱锥的侧面拼合起来时，不仅有连个面被遮住了，还有两对两个面恰好重合成了一个面的情况。所以应是9—2—2=5（个）面

单新的问题又来了，按照上面的推法，正三棱锥和正四棱锥侧面拼合后就不能是7个面了，也就是原来的标准答案错了。我又仔细读了读题，发现以下三点构成了一个特例：

1·正四棱锥

2·它们的棱长相等（即底棱和侧棱都相等，并和上一条构成了特殊的正四棱锥和正三棱锥的形状）

3·侧面（限定了贴合方式）

只要有以上三点，就一定是5个面，而不能使7个面。

看来还真是“纸上得来终觉浅，绝知此事要躬行“呀！

Dear Mr Pan:

It has been a long time since I wrote the last letter. Nowdays, people write letters less and less, instead, they make a call or send a SMS. However, it is still a good way for us to communicate with each other by sending a letter.

Its my honour to get the chance to write to you. "Approachable" is my first impression of you, because you always keeps smiling. Students may fear the teachers that are serious both in and out of class. Smile makes a teacher popular with his students, you are a teacher of this very kind.

You always arrive at the classroom ahead of any of the students, from which we could imply that you are a diligent man with regular habit. Before the class, you like to talk to us, at this very time, you are more a friend than a teacher. To be honest, I was surprised in the first class when I learned a teacher at your age could speak English in such a fluent way.(I didnt mean you are old, youre young at heart.) Moreover, you know well how to keep your class attractive. Youve got such an active mind that you can keep talking during the whole class without a pause. I always appreciated your ideas and enjoyed listening to you. In your class, I learned not only the writing skills but also the presentation skills as well as much knowledge of other areas. Thanks for your excellent teaching.

Ive got some suggestions for you. It seems that we students have got few chances to participate in discussion during the class time. Most of the time, we are listening. Seldom did we express our own ideas. I suggest that teachers should interact with students more frequently in the class. Besides, Id like to practice writing more, so would you please leave us more assignments?

Happy new year.

With every good wish.

Yours sincerely Dali Wang
