人口问题的英文作文【合集20篇】

漫漫人生，问题重重。重要的是用于消灭问题，更重要的是善于战胜问题。因此我们要换个角度看问题。

在此方面，外国人是我们的老师。自由女神像竣工后，纽约广场上残留了大量建筑的残渣和尘土。政府悬赏一万美元，仍然没有人自愿清理。这是一位年轻人主动请缨，她把尘土卖给花店，将铜渣加工成铜把手。最后，他竟然赚了几百万美元。这不是偶然，而是必然。他想到的不仅是这些废物，而更多的是其背后巨大的经济利益。换个角度看问题，废渣也是聚宝盆。

换向思维也可以帮助我们走出人生的困境。伟大的发明家爱迪生的实验室有一次起火了，他的成果被付之一炬。但他坦然的说：“我承认我很不幸，但这更意味糟糕的东西已经消失，我可以从头再来。“他没有十一儿这一件事看成是一个悲剧，而是想到了糟糕的东西也被付之一炬，从此他可以心无杂念地开展一番新事业。

如果这件是的主人公是一个悲观主义者，那它定会悲痛欲绝，了了终日，陷入深谭，而不能自拔。

既然换个角度看问题如此重要，我们该如何培养这样的思维方式呢？首先不能养成死钻牛角尖的习惯，凡事从多种角度考虑。八人际间的关系出现危机时，学会从他人的角度看待问题，以求达到共识。遇到挫折与失败，和一把它看做动力这样就可以避免走进绝望的阴影，顺利摆脱困境。

看到落叶飘飘洒洒，我们应该看到新叶绿满枝头。鹰把“自残“看成是新的生命的扬帆起航。蜗牛走得慢，自有他的道理，透过现象看本质，换个角度看问题，人生或许会因此不同。

今天，我在沙发看电视，爸爸突然走过来问我：“梦梦，你平时刷牙是从右边刷的，还是从左边开始刷的。”

“你啊你，又来打断我看电视，我当然是从左边开始刷的。”

“我就知道你从左边开始刷的，我跟你说，你妈妈告诉我说刷牙一直要从右边开始刷。”

“你真是的，你管她干啥，她虽然是医院的副院长，干什么也不知道，再说，这个刷牙从左边还是右边开始有什么关系啊。你别去理她，你也不要来打断我看电视，去，去，去。”我一脸烦恼地说。

“我就要打断你看电视，”爸爸说着，就把我的电视给暂停了，“我跟你说，你妈妈今天去人民医院的牙科，那个李阿姨说——。”

“什么李阿姨，你别理她。如果还什么话要说就一次赶快说完。”

“那个李阿姨说刷牙一定要从右边开始刷，为什么呢？因为李阿姨说每年的牙齿蛀了的人都是右边多一点。因为每次刷牙的时候，正常是右手拿牙刷，刷右侧牙齿会有点费力，需要注意力更集中一点，我们一开始手很用力，前面的牙齿会刷的干净一些，可是如果从左边刷起，左边就会干净一些，可是我们刷到后来就会草草了事，就会不干净，我们就要从右边开始刷，知道了没？”

“如果你是左撇子的话，那应该从右侧的牙齿开始刷了。”我回答说。

爸爸说：“你说的非常正确。”

“知道了、知道了，不要再打断我看电视，快走开。”

“你一定要记得，我要来检查的。”

“我知道了，快去，不要再来了，去，去，去。”

关于考试作弊的(About cheating in exams)－共三篇

第一篇：

It is known to us that some students cheat in the examinations at school.

Why do students cheat? For most of the time, students cheat because the exams are too hard for them. It’s easy to see that they haven’t studied hard enough to pass the exams. Others may want to get a higher mark by all means--frankly speaking, they want to be praised or even admired.

As a result, exams certainly become unfair for non-cheating students. And soon the majority of the students will learn and choose to cheat in exams so as to “follow the style.”

Therefore, we must take measures now. First, students need an honest study environment, and second, they should be told to pay more attention to the discipline and seriously obey it all the time.

In a word, students can not cheat on any account.

林清玄曾说过：“山谷的最低点正是山的起点，许多走进山谷的人之所以走不出来，正是他们停住了双脚，蹲在山谷烦恼哭泣的缘故。”我们往往都会选择前进，却一次次将自己陷入困境之中，最终停留在原地或原路返回。总会有人站出来评价说：“是他没有坚持，是他选择放弃。”放弃是什么，是遇到挫折的后退，还是半路的返回。其实都不是，有时放弃是在衡量自己力量后的正确抉择。有些人一直都在寻求胜利，却忘记了用智慧看问题。

龙应台曾说过：“人生是一条从平原走进森林的道路，一旦走进森林，就必然会有草丛与荆棘挡路。”我们都只知道不顾一切的前进，却忘记了森林中充满艰险。我们应该选择另一条道路，从空中前进，在空中不但没有太多的艰险与阻拦，还可以纵观森林的脉络。胜利者不是一味的披荆斩棘的通过，而是观察并发现另一条更好的道路。

古代一些清廉的官员，不畏强权的在官场中拼搏，认为自己可以成为改变官场的一股清流，却忘记了“近朱者赤。近墨者黑”纵使你有过人的智慧和坚定的意志，却也会或多或少的沾染痕迹。他们却忘记了在权力的至高点有一个可以改变这种状况的皇帝。我们往往只考虑自身的能力来改变事物的状况，却不会与一个可以改变这种状况的人一起。

我们在面对问题时，如果可以考虑自己的能力，并结合另一个人的能力来完成一件事，那样我们既有了一股力量，又有了事半功倍的能力。那么又怎会实现不了或才发现必须原路返回。

在面对问题时，我们应用智慧看问题，发现问题的所在，并解决问题。

Not until I arrived at home after watching the movie ”Peddington Bear” with my family when a feeling of warmth and strength suddenly came to me. It’s about love, it’s about family.

The plot of the movie is really simple, even predictable and a little bit cliche. However, it’s so rare for me to meet such a snug film. Maybe there’s some resonance between the core topic ---- family and myself, or, it’s just relaxing and touching, depending on how you look at it.

The film has little input and obvious theme (dream, kindness, tolerance, trust, and love... Americans love that!), and you can even see it as an advertising video made by the U.K. Government! But, things always act like that---- the simpler the emotion is, the easier we forget. The film has it’s meaning to arouse something ignored by us. And treasure everyone, everything you have.

You can either imagine family as a gasoline station, or the safest harbor. Family won’t mind your lose, your excuse, your fault, it will give you a hand, and ask you to have a rest. Family is the most supportive one behind you, forever and always.

Good luck to everyone!

Dear Mr. Lai,

尊敬的赖老师：

I am writing this letter just want to say thanks to you. I am going to graduate in two weeks. You have been my class adviser for three years. During these three years you have spent lots of energy on us. You are not only teaching knowledge in the class, but also care our life. Sometimes we are afraid of you, because of your strict requirement for our study. However, you are so helpful in the daily life. No matter what difficulties we are in, you will help if you can. So, I also want to say sorry to you for making so much trouble. But you bear all my trouble. I don’t know what kind of class adviser I will meet in the future study, but I will remember and appreciate you forever. I want to say thank you again.

我写这封信只是想跟你说声谢谢。还有两周我就要毕业了。你做了我三年的班主任。在这三年你花了那么多精力在我们身上。你不仅仅在课堂上传授我们知识，而且在生活上也很关心我们。不过有时候我们有点怕你，因为你对我们学习的严格要求。不过，在日常生活中你是那么的乐于助人。无论我们遇到什么样的困难，只要能够帮得上忙你都会帮我们。所以，我还想对你说声对不起，给你带来那么多的麻烦。但是你都一一包容了。我不知道我会在今后的学习中遇到什么样的班主任，但是我会一直记得你、感激你的。我想再次说声谢谢。

My hometown really beautiful, I love my hometown!

My home town is a beautiful place. It stands beside a wide river and is rich in fish and rice.But in the old days it was a poor and backward little town. Many people had no work. They lived a hard life.In 1949 my hometown was liberated. Since then great changes have taken place there. The streets have been widened. Factories, schools, hospitals, cinemas and theatres have sprung up one after another. The life of the people is greatly improved.I love my hometown. All the more I love its people. They are working hard so as to make it still richer and more beautiful.I am from ShenZhen. In spring ,the weather is warm and wet. I can play kite. In summer, the weather is hot and wet. I can swim in the swimming pool. In the autumn, the weather is cool and dry. I can play kite, too. In the winter, the weather is cold and dry. It never snow.Welcome to my hometown! Shanghai is my hometown. It is a modern and busy town. It has a long history. There are many big supermarkets, beautiful gardens and good factories here. It is very easy to go shopping. You can see big trees and nice flowers. There are many restaurants in Shanghai. The food tastes very delicious.You can enjoy eyery minutes of it. Many visitors come here to enjoy it.

夏日的街上，炎热的太阳高高的挂在空中，稀疏的云在顶上流着，空气中弥漫着汽车排放的废弃和垃圾的臭味，在满头大汗之下，还得捂着鼻子避免闻到臭味，这真是一件很无奈的事。

近几年的天气变得很奇怪，在太平洋形成了很多台风，甚至还有许多双台风。在欧洲常常会有热浪，这使得德国的易北河水位下降到90公分，受到最大影响的是法

国，一共上百人热死。在美国的纽澳良，还产生几乎把整个城市摧毁的飓风，而且各国海域的水位因为冰山融化，升高了10到15公分。这些如巨兽般的种种现象其实都出自人类。

科学家说：这些问题都是温室效应造成的，它的产生是因为过多废气吸收了地球用来阻挡阳光的辐

射，所以太阳可以直直的照进来，使得气候产生了巨大的变化。面对这个全球变暖的现象，一些先进的国家签了京都议定书，签署的国家要少量排放主要以二氧化碳CO2为主的和其它会破坏大气层的气体。但是许多国家为了保护自己的利益，拒绝配合这个协议上该有的规定，所以变暖的现象还是不断的恶化。

为了避免这些事情再度发生，我们应该也尽一份力气来保护地球。虽然我们还是小孩，但是还是可以做一些举手之劳的事情，像随手关灯、多吹自然风，没必要时最好不要开冷气还有要随手关掉没有在用的电气设备，这都是节省电力的好表现。

我们还可以劝爸爸妈妈多搭乘大众运输工具，少开车，而且可以的话最好是骑自行车、滑滑板车或走路，但是如果真的要开车的话，尽量开省油车，这样对减少空气污染有很大的帮助。此外还可以使用一些像是太阳能板的绿色能源来减少电能的消耗。

既然我们不想要忍受炎热的太阳、恼人的臭味和恐怖的灾难，那就从你我开始吧!爱护地球，珍惜每一个有限的资源，一人一小步，世界大进步，我相信地球一定会变回以前的好山好水好风光。

Good morning, everyone! I am glad to be here for this interview. First, let me introduce myself to you. My name is Qin Jiayin. I was born on April 23, 1981. I am a local person.I am graduating from Jilin Normal University this June. I major in Chinese literature. I hope I could get the opportunity to finish my postgraduate courses in Jilin University which I have desired for a long time. I have the confidence because I have such ability! I am a girl who is fervent, outgoing and creative. At the same time, I think I am quick in mind and careful in everything. I am looking forward to my postgraduate studies and life. I will soon prove that your decision of choosing me is the wisest. Thank you for giving me such a valuable opportunity!

Reasons for taking postgraduate exams:

First of all, I love my major. Chinese literature is the symbol of the start of Chinese literary modernization. It plays an important part in modernization of our citizens’ thoughts. What’s more, modern literature is very close to our daily life and it can deeply reflect the styles and features of our society. I am fascinated by the great masters’ refreshing or warm or profound styles as well. But I am not easily satisfied with such superficial knowledge. I hope I could have a better understanding in modern literature by studying further. This is a very important reason for me to take the postgraduate exams.

Next, I love the feeling in the university. It is full of youthful spirit. And I am deeply attracted by the scholarly atmosphere. And the most important, it’s my great honor to open my ears to your teaching.Finally, I want to talk about a very practical problem. That is my dream of becoming a teacher in the university. I want to realize my dream and make myself to be a well-qualified person. I think the postgraduate studies can eich my knowledge and make me competent in my future job.That’s my simple and clear reasons why I took the postgraduate exams.My university:

I’m graduating form Jilin Normal University this June which has a history of 50 years. It shares many same characteristics with Jilin University. Both of them have a refreshing and scholarly atmosphere. Four years’ studying there made me an independent, optimistic and strict girl.

I appreciate the education my university gave me.

Thank you for your time!

有一句话说的好：“读书破万卷，下笔如有神。”也就是说，多读书，多积累，文章就自然能写好。因此，我也在平时的空闲中，多多读书，今年暑假，我读了一本有趣的书——《那些古怪又让人忧心的问题》。

《那些古怪又让人忧心的问题》这本书，是美国的兰道尔·门罗所写，作者门罗用幽默的口吻，回答了一个个看似古怪、可笑的，但又不无道理的问题。

在“用乐高积木搭桥、地球的最后之光”等等问题中，我琢磨了一个关于：“如果在地球上捆上绳子（绳子也就是地球剖面的周长），然后将绳子抬高1米[也就是绳子离地1米]，需增加几米绳子？”这个问题我思索着，突然灵光一闪！求绳长就与周长有关，那么圆的半径增加1米后，周长就多了1乘“π”米（“π”取3、14），也就是3、14米！天啊，原来只要这么点绳子，真是神奇！

在发现了这神奇的答案后，我也相信了作者所说的：“再荒唐的问题，都有一个科学的解答！”

读了这本书，我在“如果人类DNA瞬间消失会怎样”这个解答中，得知了人体DNA的重要性。如果失去了DNA，你就会像“人间蒸发”一般，医疗追踪会失去作用，而你的身体也会慢慢改变：肝肾等器官会慢慢衰竭，所以，失去DNA会使你“隐身”，也会使你与明天说再见！

读完这本有趣的书，我也看到了科学的另一面与探究对我们而言的重要性。我们也要向《那些古怪又让人忧心的问题》这本书的作者：兰道尔。门罗学习他的探究、发现精神，因为发现更多，学的也更多！

在生活中，在学习中，我们也应该多多提出问题，多多发现问题，而不是对问题视而不见，或压根儿没发现问题，我也要继续加油！

我爱读书，我爱书香，因为读书让我受益匪浅！

my dearest mother，

the mother‘s day is coming and i would like to say “happy mother’s day” in

this letter. i love you and thank you so much for everything you did for me.

this day，i will stay away and can‘t give you my appreciation at home. i know i

will watch myself，so don’t worry about me. i am doing very well on my study. my

schoolmates and teachers are all very nice. though i can‘t be at home， i hope

you have a wonderful mother’s day.love，

西班牙曾有位叫彼得罗一世的国王，他对于很多人来说，是正义的象征。这天彼得罗一世宣布他将公开选拔法官。

三个人毛遂自荐，一个是宫廷的贵族，一个是曾经陪伴国王南征北战的勇敢的武士，还有一个是普通的教师。在宫廷人员和三个候选人的陪伴下，国王离开王宫，率领众人来到池塘边。池塘上漂浮着几个橙子。

“池塘上一共漂着几个橙子啊？”国王问贵族。贵族走到池塘边，开始点数。

“一共是６个，陛下。”

国王没有表态，继续问武士同样的问题：“池塘上一共漂着几个橙子啊？”

“我也看到了６个，陛下！”武士甚至没有走近池塘就直接回答了国王的问题。

国王没有说话。

“池塘里有多少个橙子啊？”他最后问教师。

教师什么也没有说，径直走近池塘，脱掉鞋子，进到水里，把橙子拿出。

“陛下，一共是３个橙子！因为它们都被从中间切开了。”

“你知道如何执法，”国王说，“在得出最后的结论之前，应该证明，并不是所有我们看到的就是事情的真相。”

这个故事告诉我们，凡事不要妄加评判。

“奶奶，我想喝冰水！”我淘气地赖着奶奶，她没有搭理，只是看了我一眼。娇气的我忍受不了这种冷冷的眼神，于是大哭起来。很快这个问题便被我的眼泪解决了。那时候的我意识到：原来解决一个问题，只要用眼泪就好了呀！

眼泪出现的情景有无数种：快乐可以流泪，难过可以流泪，感动也可以流泪，但如今的我带着泪却显得意味深长。数学作业是在逐渐变难了吗？为什么我老是不及格。虽然我知道自己的数学水平是什么样的，可是我仍然很不甘心。我很想挑战，也很固执，即使我知道有时候自己很愚笨。

一天，我把所有的我认为简单的科目都做完后，拿出了数学习题，虽然老师布置很少，只有两面，但是我却用了差不多两个小时来完成。不知不觉，我竟然做了那么久，并且第二天去学校发现自己只做对了几个题目。不是说努力就会有成效吗？可是我却看不见我的成果。我一直相信“世上无难事，只怕有心人”的箴言，但现在数学已经彻底打败了我，我似乎找不到正确的路。在数学这个方面我选择了放弃，每天我只想抄完答案就行，这只是为了完成任务而已。

终于期末考试到了，我意外地只考到了50多分，这是我历史最低的数学成绩。我之前不是都会在70分的边缘吗？现在为什么这么少了？我不敢相信这个成绩是我的，于是我选择了逃避，选择了装傻。我好像颓废了似的，整天只知道看电视睡觉，我想机器人也不过如此吧。为了不让爸爸知道自己的成绩，我把手机关了机。这次我彻底地放弃了，因为换做以前，我可能还会自己关禁闭。

都说每个人的心中，都有个魔鬼和天使。就在我灰心丧气的时候，我心中的那个天使并没有放弃我，它劝我改过自新。我勇敢地告诉爸爸自己的成绩，爸爸过来训斥了我，问我是替他学习还是替自己学习？我流着泪，咬着嘴唇沉默了，但我在心里暗暗发誓：以后一定要好好学习，为自己而学。

在后来的学习过程中，我带着这个信念向前迈进，不断克服一个又一个难题。因为我知道：如今的我，虽然仍然继续流着泪水，但流过的泪不再稚嫩，而是一种解决问题的不屈与坚定。

A suichu fireworks, energy-saving - signature

With the sound of familiar firecrackers in the ear, the taste of the year became thicker and thicker. The eyes see, the ears hear, the nose smells full of jubilation.

Spring Festival comes, we are very happy, all families have attached to the couplet, and the word "Fu", "Fu Fu" is the meaning of "blessing". With regard to the origin of "Spring Festival", there is a kind of legend that there was a kind of beast called "year" in ancient times of China. "Year", head long antennae, ferocious abnormality. Long years of deep seabed, each to a specific day (which is now the new years Eve) to climb the shore, devouring livestock harm human life. Therefore, every new years Eve, people help the aged and the young stockaded village fled to the mountains, to avoid "year" damage. One year on New Years Eve, the old man begged from the village. The villagers rush to a scene of panic, no one cares about him, only village as an old woman gave the old man some food, and urged him to speed up the mountain to avoid "year", the old man pulled up to the mustache smiled: "if her mother let me stay at home one night, I have to years away." The old woman continued to persuade the old man to laugh without saying.

So there must be fireworks in the Spring Festival

The fireworks in the sky diversiform dressed in brightly coloured, "fireworks into the sky", "bang" sound exploded, the sky suddenly become colorful, the faint powder is like colorful flower blooming. But the drama is not long. The fireworks are fading slowly from the sky until they disappear. Over there, a shock silver light caught my attention, and it sprayed and sprayed up. Falling back then jumped out of the silver, like pearls falling from the sky to tens of thousands of people, very beautiful feeling; snapping, snapping, the deafening sound of firecrackers is certain! The noisy sound is enough to add a lot of joy to the 2013.

There is a warm fire, burning, and intensified, the orange flames rolling up and down, as if calling what, like dancing in joy. People, things, China, the Spring Festival is becoming more and more intense, bringing 2013 new weather!

The Spring Festival rich in the rich years, the rich people.

最近我学习了一个购物问题，这个问题与生活实际关系密切，下面我来讲一讲。

“由于店面的经营需要一定的花费，通常一套西服的售价需高出进货价20%才能不亏损。而为了经营的利润，某店主将一套西服高出进货价50%挂牌销售，标价为600元。但近期销售状况不好，店主决定打折销售。请问：店主最多打几折，才能不亏损？”

看到这道题后，我感到很奇怪，于是我跑去问爸爸：“爸爸，为什么一套西服的售价要高出进价的20%才能不亏损呢？不是应该只要高出进价就已经赚钱了吗？”爸爸笑着对我说：“你开一家店，不是要花水电费、人工费、店面的租金和税费吗？”我疑惑地说：“当然了。可是这和高出20%才能获利有关系吗？”。爸爸说：“这20%的利润都是为了支付水电费、人工费、租金和税费等费用啊！，”我恍然大悟：“原来是这样，我明白了，也就是说成本要包含这些费用，所以成本会高于进价，这样理解对吗？”爸爸说：“对呀！要把所有的费用合到一起才是成本。”

回到我的房间，我仔细的思考了一下这个问题，以前一直以为成本就是进价，原来成本要包含这么多的费用，怪不得我们买的东西贵呢？如果没有这些费用，成本下降了，我们买的东西就便宜了。但是没有钱赚，商家没有钱赚，他们就会破产了，要挨饿了。所以他们一定要加上这些费用，市场才能繁荣。

停止思想上的飞奔，我不得不回到如何计算这道题上。经过分析，我有了解题的思路。首先，我可以用西服的标价和50%的加价，先算出这套西服的进货价，然后再求出成本。接着再由成本除以售价再乘上100%，即可算出店主最多打八折，才能不亏损。

今天我又学到了一个与生活息息相关的知识，我感觉开心极了！

阳光透过树叶的间隙洒落在我的窗前，我终于睁开那迷蒙的双眼，准备迎接新一天精彩到来。微风将白云从吹散了，我些许的倦意似乎也被吹散了，无意间望见生长在烂泥之中的橘子树，可我并不担心，因为它依然那么翠绿挺拔。

在归去的途中，我又似有意无意地朝那望了又望，终于我从烂泥之中拔起了它，以尽可能快的速度回到家中，将它栽在院落中，与其它种植作物生活在一起。院落很大，阳光充足，何况我还会悉心照料，我想，它一定会生长得很好。心中一直这样想，感觉心中有个可爱的小生命在向我朝手，许多植物都似

乎披上了一件金衣，向我展示它们的魅力。我打开笔记本，记了下这个难忘的时刻。

暴风雨来了，我急忙奔向院落，却瞥见橘子树叶子掉落了，虽然依然翠绿，

但躺在地上零零落落，如同一只奉上祭坛的大鸟掉落的羽毛，低吟着壮烈的悲歌离去。我不禁望向乌云连绵的天空，仿佛是它为我改变植物的命运而感到不公，雨夹杂着微风从空中飘落，时间仿佛在那一刻停止。我抱怨着时间的冷漠，在我尽情采取幻梦花朵时，依然分秒不差地滴答着，却在失落时让我沉默。

为什么橘子树在舒适的院落里会掉叶，而在烂泥中却能茁壮成长？我在拔起它的那一刻并未思考过这个问题。对啊，这大千世界，万象纷呈！行走其间，总有令人沉醉之处，也一定会有令人伤心之时。而今我的忏悔是否能填补它心中的失落？

当阳光再次照进我的院落之时，我则已将橘子树移回烂泥之中。只希望还它一个自己喜欢的生长环境。过了一段时间，当我再一次到烂泥中探寻时，我惊喜地瞪大双眼，橘子树枝头又重新泛出了绿意。我感叹道：原来这是你的选择！

徘徊在心头多时的问题成功得到了解决，那就是万事万物都有它自身的生长规律，怎样选择，那是它的不二法则。
