水污染的英文演讲800字【精彩20篇】

Dear Zhang Wei,

I’m glad to know that you are coming to my city during the summer vacation.

However, I’m afraid there’s some bad news. I’m planning to take part in an international conference to be held in another city during the time of your visit.

All the top scientists in my field will show up at the conference. More importantly, I’m lucky enough to have been selected to give a speech on behalf of my research team at the Conference. I really can’t miss it.

I understand that it’ll be your first time to this city and I’m your only friend here. I’ve asked my roommate to meet you at the airport, and you can stay in my room.

He is a very nice person and he will show you around the city. Hope you two will get on well and have a nice holiday!

Yours,

Li Ming

治疗爱的创伤唯有加倍去爱。

There is no remedy for love but to love more.

热烈的爱情是不可抑制的渴望。

Passionate love is a quenchless thirst.

生命虽短，爱却绵长。

Brief is life ,but love is long.

天下有情人终成眷属

May I wish that all Jacks shall have Jills, all shall be well.

这世上最美妙的感觉无非是您爱的人正好也爱着你!

The best feeling in the world is being loved back by the person you  love.

希望你的心上人早日出现。

祝你们朝朝暮暮，缠缠绵绵到永久。

May you two linger on each other every day and night till the end of  time.

爱与喜欢是有区别的。如果你喜欢一朵花，你会摘下它，但你要是爱它，你会浇灌它。

Theres a difference between "love" and "like". If you like a flower you  will pick it, but if you love a flower, you will water it every day.

尊敬的各位老师和各位同学们，大家下午好：

我是来自七10班的郑静仪。今天我演讲的主题是《为梦想远航》。

海阔凭鱼跃，天高任鸟飞。每个人心中都怀揣着属于自己的梦想。同学，你有过梦想吗？

小时候我有一个梦想，我希望自己可以有许多钱。大人问：“有了钱你要做什么？”我天真地回答道：“我要买很多糖果。”的确，小时候的我们天真无邪，幸福与快乐是一曲不变的乐章；再稍微大一点，我上小学了，我希望能够成为一名班长，帮助老师管理班级；中学，梦想又变了，我不再是那个整天想着吃糖果或当班长的那个幼稚的孩子，现在的我希望可以成为一名尖子生。回到家可以受到家长的表扬，在学校可以得到老师的肯定；在同学之间有鹤立鸡群的表现。但是，渐渐地，我发现实现这个梦想不能只耍孩子气。之后，我学会了奋斗。

梦想不分大小，但它能给我们带来希望，为我们指引前进的方向。在我青春的视线内，我似乎看到了李娜的身影。当她打败斯齐亚沃尼后，幸福的倒在红土场上……法网的冠军奖杯上刻下了这样一个崭新的名字——李娜。李娜之所以能够取得令人骄傲的成绩，是因为她不懈的坚持与奋斗……在她实现梦想的过程中也曾受过伤，放声大哭过。但她仍旧坚持着自己的梦想，最终实现了它。

另一位杰出的人物是意大利的达-芬奇。他也梦想自己的未来，但他更多的是想现在该怎么做。为了练好基本功，他曾不停地画那外形单调、乏味的鸡蛋。他常说：“勤劳一日，可得一夜眠；勤劳一生，可得幸福长眠。”他憧憬一生的幸福，但却要求自己勤奋的战斗一生。行动，切实的行动，是通向梦想之门的轨道；实现梦想，是一场艰辛的无休止的马拉松赛。只有坚持才会到达顶峰。

所以，无论岁月在我们脸上增添了多少皱纹，无论世事在我们胸口划过多少道伤痕。只要我们还有呼吸的权力，就拥有重塑梦想的激情；只要我们还有生存的氧气，就拥有缔造激情的勇气。

同学们：让我们一起为梦想而拼搏吧。

我的演讲结束了，谢谢大家。

尊敬的市长：

您好！

您知道吗？随着我们人类科技的发展，环境的破坏也越来越严重，无数工厂排放出来的废水使得周边的河流受到了严重的污染。玉坎河就是个很好的例子，曾经的玉坎河生机勃勃、河水清澈见底，还有无数的小鱼小虾在里面嬉戏玩耍。如今的玉坎河里面已是臭气熏天，路过的行人几乎都是掩鼻而过，绕道而行。这，就是我们人类行为导致的恶果。

醒醒吧，人类！这是河水妈妈的呼唤。无数污水被排进肥沃的土地，使得土地里的庄稼变得枯萎，影响庄稼生长的态势和年产量。醒醒吧，人类，这是河流妈妈的呼唤。不计其数的垃圾被随手丢弃在河水里，使得河水不再清澈，鱼虾绝迹。醒醒吧，人类，这是河水妈妈的呼唤。人类将数不胜数的垃圾、有害电池、污水……排进河水，将曾经澄澈、明亮的河水变得浑黄不堪，让人看了痛心疾首。

我们应该做到不乱扔垃圾，把生活垃圾丢进固定的垃圾桶。我们可以组织专门人员重新彻底清理河流里的污水，将浑黄的水源彻底抽干掉，拾走里面的垃圾，重新注入新的水源。

针对治理河流污染的问题，我提出以下几条建议：

1、不把污水、废水等排放到清澈的河水里面，让我们携手共建美丽、和谐的玉环；

2、宣传保护河流的意识，带动身边更多的居民加入到这个活动当中来，从身边的每一件小事做起，为重现河流的原貌贡献自己微薄的力量；

3、建议有关河流治理的部门加强整顿力度，对于再次污染水源的行为采取合理的惩罚措施；

4、组织志愿者队伍，定期在河流附近拾捡垃圾，减少对河流的再继续污染。

在此，我号召，我们每个人都应该有保护水资源的意识，不浪费任何的一滴水。我们平时洗完脸的水，可以重复利用，比如浇花、拖地等。我们应该合理利用生活里的每一滴水。不要让地球上的最后一滴水成为人类的眼泪。让我们共同努力，重现玉坎河的原貌吧！保护河流的行动，已是迫在眉睫！

[关于治理水污染的建议书600字作文

With the development of the Internet, many people are used to shopping

online. It has become a fashion in our daily life. Some of us students also join

the group.

Shopping online has many advantages. Just by a click of the mouse, you can

buy what youre interested in without going outdoors. You can avoid getting

tired and being trapped in the crowded people and cars and save time. When

shopping online, you can choose from more varieties of goods, whose prices are

generally lower.

Every coin has two sides. Its disadvantages are obvious, too. On the one

hand, its very easy for you to buy goods different from the pictures you see on

the Internet. On the other hand, shopping online may cause people to buy goods

that are not badly needed. Thats a waste of money.

All in all, I love shopping online.

老师们，同学们，大家好，我们是来自初一九班的张影和李雨亭，今天我演讲的题目是“冬季长跑好处多”。

俗话说“冬训吃一年”，这是体育业内人非常重视的训练阶段。在民间利用寒冷的冬天进行长跑活动更是人们喜闻乐见的体育项目。为了让同学们更多的掌握长跑的知识，更好的参加长跑运动，我们在此向同学们介绍冬季长跑的有关知识。

通过长跑可以调节神经中枢的兴奋与抑制合理的交替转换，避免神经思维中枢紧张过度，消除大脑的疲劳，提高学习效益，提高记忆力；在低温下长跑可以刺激、激活肌体的保护性反应，调节大脑体温中枢的功能；长跑还可以促进血液循环，加速脑部的血量，供给大脑更多的氧和营养物质，使大脑清醒，思维能力敏捷，神经系统功能的改善，可以提高和完善对各器官、系统的控制和调节能力。

长跑运动可以增强心脏肌肉收缩的力量，提高血液中红血球携带氧的能力，可以使血管粗壮有弹性，可以激活淋巴细胞提高人体的免疫功能。在长跑运动时由于需求氧的量成倍增多，呼吸次数及深度也随之增加，经常进行长跑就能有效的提高呼吸肌力量，加大肺泡的通气量，从而提高了肺活量。

人体的运动系统是由骨骼、关节、肌肉组成，经常参加长跑运动，提高关节的灵活性；有效的提高肌肉的力量和耐力。

冬季长跑可以重新塑造完美体形、体态长跑属于有氧代谢运动，在运动中需要大量的氧和营养物质来供给人体运动的需要，在运动中多余的脂肪被消耗掉就能使得原本臃肿肥胖的体形得到改善，达到重新塑造体形的效果。

在冬季长跑中由于受到季节温度和环境的影响会遇到很多的困难，如天气寒冷，空气干燥都是对人在跑步时形成的自然困难因素，在这样的环境中锻炼一方面在锻炼体质，另一方面也是对人的意志品质的锻炼。

冬季长跑是一项锻炼身体的好运动，我们只有采用科学的方法进行锻炼，才能得到良好的锻炼效果。希望广大同学积极行动起来，投身到冬季长跑活动中来。

我的演讲到此结束，谢谢大家！

My mother has a pair of keen eyes which can speak.With her eyes,she observed my mood,gave me courage and made me strong.Therefore,I could face difficulties.

When I was a baby learning to walk,my mother always lent me a hand and encouraged me to get up while I fell down.

As I finally threw myself into her arms,her eyes smiled with praise.Later as I grew up,I met with more difficulties.But whenever I was frustrated,my mothers eyes always gave me hope and encouragement.Once I failed in exams,my mother encouraged me to find out the reasons.

Instead of blaming me she pushed me to do better.At last I overcame the difficulty.Now I have grown up and become more independent,but whenever I come across setbacks,my mothers eyes are always with me encouraging me wherever I go.

People often say that gold and silver are the most valuable things in the world.But

I dont think so. In my opinion, to read books is more valuable than anything else.

The old saying “To open a book is always helpful” clearly tells us how good it is to read a book.

Books are our friends. They introduce us different kinds of knowledge. They lead us down the road to success.

Books are our teachers. They teach us troth, science, literature, and philosophy of life. Besides, they increase our knowledge, enlarge our experience,strengthen our character and do many other things which we can not do without them.

Books tell us what is good and what is evil. And only books can tell the good from the bad.

Therefore to read more books is the best policy for our young students.

Our English Teacher Our English teacher， Ms Huang， came to our school in 1970.

She has been an English teacher for more than 30 years.

She works hard and has been a model teacher for many years. She is kind and friendly to us after class， but She is rather strict with us in class.

She always encourages us to speak and read more English.

She often says，"Practice makes perfect." She is good at teaching and tries her best to make every lesson lively and interesting.

She often gives us slide shows， teaches us English songs and helps us to put on short English playS. She is not only our teacher but also our friend.

We all respect and love her. Tomorrow she is going to attend an important meeting， at which she will be given a medal for her advanced deeds.

Leifeng was known as a pattern that offered help to others selflessly. He

devoted all this life into his beloved career as well. I, myself, was totally

shocked by his character.

Such is human nature; people trace the good, water flows to low. Everyone

should copy his sprit as our daily life goes instead of uttering a meaningless

slogan “learn from Leifeng, our decent idol”, so that we could definitely see a

lot more smiling faces rather than conflict.

To help others is not a hard thing, however, what you need is to consist

doing it. Take myself as an example. I am the representative of Math, to collect

homework is my daily task, however, I would turn them to the right page for

shorten the time for teachers when correcting them.

I strongly propose that we shall see a better world if each of us treat

Leifeng as our model and copy his spirit.

The fast-developing cities severe environmental imbalance constructs the high demands of productivity and low demands of living standards of the daily lives. The butterfly effect is the main approach towards the promotion of environmental protection. Its inefficient when only one person whos acting on protecting the environment, but if one starts the others would follow. Teaching environmental protection in early age is also crucial since the inconsideration of pursuing short-term interest not only set the milestone for the public hazard, but also the destruction of our planet. Moreover, the environmental protection should be the priority for the future of all countries, for good standard of living starts by embracing the ecological balance of the nature.

Dear Emily,

Im glad to learn that youre interested in China. Im more than happy to introduce you more of China. China, being one of the four ancient civilizations, has a long history and therefore there are many places of ancient sites. Besides, China has a vast region hence many beautiful natural sceneries are found in China as well. And due to the long history and vast area, there are in total 56 races living harmoniously with huge populations in China. China has not only ancient sites and sceneries, also she has modern metropolitans such as Hong Kong and Shanghai which attracts millions of travelers each year As an old saying, talking is nothing more than seeing. I hope you can come and visit China yourself and view these beautiful sceneries with your own eyes.

Yours Sincerely,

Hua Li

How do you define loneliness? I often walk alone, should I call myself a

lonely girl?

Nowadays, it’s a common phenomenon that college students fall in love with

others because they cannot stand loneliness. In my point of view, I believe that

people with a strong will to finish something won’t feel lonely. Many people

feel lonely when they are boring, nothing to do. That is to say, if we have many

things to do, work hard for our dreams, live a meaningful life, we won’t feel

lonely. Our dreams will accompany with us.

In my opinion, I think people who don’t know what they want are lonely,

because they have no destinations in their life. They are lonely in soul. So I

don’t consider I am a lonely person, because I have dreams, I have best friends

on my road to succeed. To a conclusion, there is no doubt that lonely in soul is

real lonely.

I am. ________. I was born in ________. I graduate from ________ senior high school and major in English. I started learning English since I was 12 years old. My parents have a lot of American friends. Thats why I have no problem communicating with Americans or others by speaking English.

In my spare time, I like to do anything relating to English such as listening to English songs, watching English movies or TV programs, or even attending the activities held by some English clubs or institutes. I used to go abroad for a short-term English study. During that time, I learned a lot of daily life English and saw a lot of different things.

I think language is very interesting. I could express one substance by using different sounds. So I wish I could study and read more English literatures and enlarge my knowledge.

As is known to us,it is very harmful to spent too much time playing games on the internet.

Firstly,it is an enormous waste of your precious time.As a student,we are supposed to concentrate our attention on our studies.Secondly, it does great physical harm to your if you are stay up so often.You are likely to suffer from body imbalance as a result of exhaustion.Thirdly,your mental health will be seriously affected,too.If you completely immerse yourself in the unreal world and deviate yourself from your parents and friends,you will end up feeling lonely and isolated in the real word.

I hope someone who likes playing computer games will manage to control this problem and shift your attention to your lessons.Try to take exercises and communicate with others more often.In this way,you will live a more colorful and fruitful life.

Dear Miss Jiang,

I am writing to share my ideas about our English class. Now, our main

material in the class is the textbook, which is reasonable. But I think we can

get some other resources, such as English magazines, songs, movies and so on. We

can learn the basic knowledge from out textbook, and get some more from other

materials. In addition, those materials are more authentic and practical, which

will be useful to our learning. Besides, by doing so, we can get more fun from

learning and develop our interest to English. Please take good consideration of

my advice. Thank you!

Sincerely yours

Bella

尊敬的蒋老师：

您好!我写信是想和你谈谈我对英语课的想法。现在我们上课用的主要材料是课本，这是合理的。但是我认为我们可以获取一些其他资源，比如英语杂志，歌曲，电影等等。我们可以从课本上学到基本的知识，同时从其他材料获取更多知识。另外，那些材料更真实和实用，这对于我们的学习会有好处的。此外，通过这样做我们可以从学习中获得更多乐趣从而培养我们对英语的兴趣。请您认真考虑我的建议，谢谢!

Hi Worried,

I’m sorry to know that you’re having such a bad time at the moment. The

truth is everyone will have one of those periods when things seem to be wrong,

so you don’t have to worry so much. The important thing is to learn to control

your temper so that you may not do or say anything you’ll regret. Here are three

useful tips:

First, talk to someone you trust about how you feel. This is a good way of

letting your anger out without hurting others or yourself. Second, go outdoors

and play team games with your friends, as physical exercise is an effective way

to get rid of anger. And third, remain optimistic about your future. Such a

positive attitude towards life can be helpful in lifting your spirits.

I hope you’ll soon feel calmer and carry on as normal.

Yours,

Jamie

waking up,but then i wash up quickly.i brush my teeth,comb my hair and put on my

school uniform.i pack my bag for school and i leave.i never miss breakfast,so i

either eat at home or eat on the way to school.but i always eat ina hurry.after

school,i go to a cram school like all my friends.i study and finish my homework

for the day.finally,i go home and i take a break.i have dinner with my

family,watch a little tv and just relax.i am usually in bed by 9:30.

this is my routine from monday to friday. however,the weekends are

different.i can wake up late and have a ball.then.i can do whatever i like.i

believe my routine is typical.it is probably a lot like yours.
