上海世博会对中国的影响英语作文【精品20篇】

The passage mainly tells us the importance of protecting traditional

Chinese culture, which is challenged or facing extinction because of the

developing society and changing lifestyle. Besides, China is nationwide sparing

no efforts to do it.

The protection of national and folk culture is of great significance to

Chinese cultural diversity and also to the harmonious development between local

economic and social development. It is reported that the Guangdong government

pays special attention to protecting Chaoju(潮剧)， a local drama born in Chaozhou

in the eastern Guangdong province.

In my opinion, some measures should be taken to protect traditional culture

effectively. To start with, we should make a law to regulate the society’s

performance. Besides, we should draw more people’s attention to it, for the more

they know about the importance of culture protection, the stronger the support

we can get from the public.

In a word, it is high time for us to treasure and develop our own valuable

culture.

长城位于北京延安区军都山关古道。它规模宏大，非常雄伟，被誉为八大奇迹之一。

长城长8851千米，宽约为5公尺，它的东南部地形以平原、丘陵为主，除了黄土高原地势较高外，大部分在海拔2000米和海拔500米。它从东边山海关一直到西边的嘉峪关，曲曲折折的像一条长龙，盘旋于大地上。

烽火台是长城重要的设施，它又称烽燧，用于点烽火台传递重要信息的高台。是古代最重要的防御设施，是为了防止敌人入侵，发现敌情所建设。每格5千米就有一座，白天焚狼烟，晚上点明灯。

长城的城墙很有建筑性，高大坚固，是用巨大的条石和城砖筑成的。顶上也铺着方砖，很平坦，并且十分宽，五六匹马都能并列走过去。城墙外沿有两米多高的成排垛子，垛子上方有方形的瞭望口和射击口，供瞭望和射击用的，非常牢固。

长城始建于周朝，从战国以来经历20多个诸候国和封建王朝的修筑，最早是楚国开营建长城，后来各国修筑自己的长城。秦统一六国后秦始皇就开始把各国长城连起，绵延万于里，遂称万里长城。

俗话说：“不到长城非好汉。”长城是中国的古代的文化遗产，非常雄伟。是世界八大奇迹之一，是中国的一张金字名片。

一年一度的春节是每一个中国人最期待的节日，也是一家老小团圆最重要的节日。我在这春节里也享受着浓浓的年味。

俗话说：过了腊八就是年。所以一进腊月，家家户户都开始忙开了，我们家自然也不例外。于是我一接到放寒假的指令就马不停蹄地飞奔老家，最开心的就是和爷爷一起上街。爷爷一大早就骑着电动三轮车载着我，上街购置各种各样的年货：春联、烟花，还有各种口味的糖果和水果等等。直到三轮车的后备箱都放不下，我俩才心满意足地回家了。虽然这样的场景每年都在重复上演着，可我的心里依旧感到满满的新鲜和幸福，大概这就是年特有的味道吧!

购置好了年货，到了腊月廿三，送完了灶王爷，我们家就到了最忙碌的时刻，全家出动开始做过年的包子了，在我们老家，包子称作馒头。爷爷奶奶拿出早几天就准备好的发酵引子，搬出一盆盆现做好的馅料，咸味的有荠菜肉馅、萝卜丝肉馅、青菜肉馅，甜的有红豆沙馅、黑芝麻馅，爷爷说这象征着五福临门，多好的寓意啊!接着邻居们也来帮忙了，只见他们把面团分割出均匀的小份，然后摊开面皮，包上馅料，把皮子折成均匀的十几道褶子，聚拢、捏紧，一个圆滚滚、白胖胖的包子就做好了，然后再把它们一个个摆好在蒸笼里，摆满围成一个同心圆。这时候大灶上的水也烧开了，蒸笼放在大锅上，大火烧开几十分钟之后，屋子里被一时半会散不开的水汽氤氲的烟雾缭绕，随着揭开蒸笼，面香夹杂着菜香立刻让人垂涎三尺，我迫不及待地拿起一个蒸好的豆沙包，顾不上烫，一口咬下去，软软的面皮裹着豆沙的香甜吃到我的嘴里，滑进我的胃里，把我的馋虫全部引出来了，三下五除二，香甜的包子就这样被我“消灭”了，真甜呀!我想，我吃进去的是包子，到达我内心深处的却是家里才有的年味吧!这种味道是期待、是忙碌、是团圆、更是深植在每一个中国人内心深处的一种幸福!

这不，吃着吃着，在外上班的爸爸妈妈回来了;吃着吃着，最热闹的大年三十就来了，和家人一起吃着年夜饭，看着春晚，伴随着窗外此起彼伏的爆竹声，新的一年就这样来了!

Dear mother:

Hello!

Mom, this is my first time to write to you, very excited, many words do not

know where to start, usually I am more willful, there are a lot of thanks to

you, and do not want to say to you. Today, let me take this opportunity to tell

you a daughters gratitude.

When I was young, you began to have long hair for me. You said girls had

long hair and beautiful hair. But this is a lot of trouble for you, but for your

daughters beauty, I wash my hair once every 32 days and comb a beautiful

hairstyle. Every time I wash my hair, Im afraid Im cold or ironed. You always

adjust the water temperature so well. The children in the community envy me that

I have a good mother.

After I go to primary school, you always get up early every morning and

wake me up after a good meal, but sometimes I still pick and pick, and dont eat

well and make you sad. But you never get angry with me. Instead, you do it for

me on the second day. On the way to school, I saw other children taking the cake

and eating while walking. I wanted to tell you, "Mom, how nice you are!"

Remember last semester, when the math unit test, there was a simple

formula, because of my carelessness made a mistake, you see after very angry,

very hard to criticize me. At that time, I almost cried by your quarrel, but I

knew in my heart that your severity was for my good.

Mom, here I want to say to you, "Mom, I love you!" You are hard! "

I like the new year, people in the Spring Festival, the spring festival couplet, watch the Spring Festival Gala, set off firecrackers, fireworks, eating hot pot … … new year is really lively!

To thirty in the big year, after eating the rich years night meal, it is time to see the Spring Festival evening. The Spring Festival Gala began, and the family gathered in front of the TV punctually, concentrating on their faces, hum and mouth dancing from time to time. The evening shows are colorful, with cross talk, sketches, singing, dancing and magic … … every program wins everyones compliments, cheers and laughter. At the end of the party, the host shouted: “ ten, nine, eight … … two, a ” the new year began.

New years first day, often to go out to play.

The 9 point is enough. That is, at 8, many people celebrate this special festival with fireworks and firecrackers. The fireworks are simply flying all over the sky, and the sky is decorated with colorful and colorful.

The new year is a lot of fun, a lot of good-looking, and a lot of delicious food.

As we all known，food safety problems are more and more popular in our

country，because more cases about food safety problem have appeared.

Firstly，As the old saying goes，the food is what matters to the people。 Food

plays an important role in peoples life。So food safety influences peoples

health and life。Secondly，some producers only think about earning money without

thinking about ensuring food safty。they produce unqualified food.Thirdly， some

food supervisory departpents dont perform their duty pletely。This behavior make

some producer ignore the safety of production.

If we want to solve problems that is illustrated former，we must call on the

supervisory department to manage the food market.And the producers must paly

their roles。 Lastly， we hope that there is law that punish illegal acts.

Campus activities have been organized in many universities and colleges.

These activities range from academic to recreational， such as academic reports，

social consulting services， speech contests， poet’s club， painting clubs，

singing and dancing groups， etc.

These activities provide students with two major advantages. First of all，

they play a positive role in improving students’ studies. Due to their heavy

schedules， students are often busy themselves with textbooks and seldom expose

themselves to a colorful life. But the variety of the activities provides

opportunities for them to relax themselves and enrich their minds and knowledge.

In addition， the activities also serve students living in the “ivory tower” have

little chance to get in touch with society. Now the activities open the door for

participants to leave their classrooms and get to know society.

All this offers an important means for students to broaden their horizons.

They believe with the right kind of guidance and help campus activities will

continue to grow and flourish.

ncreased stress results in increased productivity--up to a point. However,

this level differs for each of us. Its very much like the stress on a violin

string. Not enough produces a dull. harsh sound. Too much makes sharp, annoying

noir, or causes the string to snap. However, just the right degree can create

magnificent tones. Similarly, we all need to find the proper level of stress

that promotes optimal performance, and enables us to make harmonious music. Good

health is more than just the absence of illness. Rather, it is a very robust

state of physical and emotional well being that acknowledges the importance and

inseparability of mind/body relationships. In the next program. I hope you will

join me in the pursuit of learning how to exploit stress, so that it can work

for you. and make you more productive, rather than self-destructive.

Nowadays, house husband has become a hot phenomenon in modern society. As

we all know that no matter what country, it’s a tradition that men play a core

role in family who always take the burden to earn money to support their family.

But things are kind of different as society develops, more and more men are

beginning to take over housework while women go out from house. In my point of

view, I think this is not a big deal.

In the first place, house husband may be a shame title for men, but when it

comes to money, there is no room for reputation. As society develops, the life

standard are rising, and everything for living is much expensive than before, if

couples want to guarantee their life quality, then they should let the one who

earn better to work, although the one is female.

In the second place, it’s fine for women to support family as long as they

earn better than men. In the past, women always were treated very badly, and

they got no rights to be educated, to work. In some countries, they can’t even

show their face to others. A traditional female role is to stay at home, taking

care of children and do all of the housework. But now, lots of women have a good

job, so that they totally have the ability to be the economic backbone.

Therefore, in order to take good care of family, men are likely to stay at home

to do housework. I don’t think it’s a shame for men, because no matter what you

do, as long as you do it well, you are successful.

To sum up, people should change their opinion about core role of a family.

It’s acceptable for women to support the family, and there is no shame for men

to do the housework. As long as you remember life quality comes first.

Since the development of the technology, the society gets modernized,

people make use of the high technology to pursue more profit. Though the

government has noticed the problem that people do to the environment, they still

can’t prevent negative result that the polluted environment brings.

Many years ago, the most prominent problem of the polluted environment is

that the river and the water were changed their color, some fish even died for

the polluted river. Now the situation becomes ever worse, lately, in the big

city, like Beijing and Shanghai, people are annoyed by the bad weather. It is

not the rainy day, but the haze around the sky, there is no way for people to

run away for it. The haze contains toxic elements, people breathe it and hurt

their bodies.

The haze problem is the result of people’s pursuit for the profit, what

people did to the environment now has been paid back by the environment. Now

people have realized the revenge from the nature is so huge, protecting the

environment is the main task. No matter how bad the environment is, people still

need to do something to fix their mistake.

Mid Autumn Festival is a traditional festival of China。 It used to be as

important as Spring Festival 。It is usually celebrated in September or October。

This festival is to celebrate the harvest and to enjoy the beautiful moon

light。

To some extent， it is like Thanks Giving day in western countries。 On this

day， people usually get together with their families and have a nice meal。 After

that， people always eat delicious moon cakes， and watch the moon。 The moon is

always very round on that day， and makes people think of their relatives and

friends。 It is a day of pleasure and happiness。 Hope you have a wonderful Mid

Autumn festival!

“三行情书”送给最美的“你”

寒冬已至，新冠疫情却没有“冬眠”迹象。手机上每日推送的疫情速报上，确诊病例、无症状感染者的数量时刻牵动着百姓的心。在这疫情防控关键时期，全国各地的劳动者们都在各自的岗位上，为疫情防控贡献智慧和力量，齐心协力抗击疫情已经成为群众的共识。在这里，笔者想借此平台，为最美的“你”作“三行情书”，愿春暖花开之时，共享平安相聚之乐。

我在这边，

家在那边，

距离却阻挡不了思念。

——致不能回家过年的“你”

今年的春运正好赶上疫情防控关键时期，为减少人员流动，有效遏制疫情蔓延扩散，许多地方响应国家号召，纷纷发出了“就地过年”的倡议。“独在异乡为异客，每逢佳节倍思亲。”对于期盼已久、归意正浓的游子来说，“异地过年”可能难以缓解“倍思亲”的乡愁，但春节团聚的情感羁绊与春运大潮的潜在风险相比，家人的平安健康才是第一位。正如古人云，心安之处即故乡。天津市的7条举措温暖人心，江苏省的现金补贴优惠多多，陕西省的文娱活动丰富多彩，政府的保障犹如一颗安心丸，是全国上下同舟共济，筑牢防疫壁垒的动力源泉。总之，谢谢“留守”的你，有了你的配合才能共同打赢这场没有硝烟的抗疫之战。

我不清楚你的模样，

但却熟悉你的声音，

你认真的言语是这世上最动听的旋律。

——致守岗位的社区工作者

你扮演了多个角色，入户排查的“赶路人”、民事调解的“知心人”、上门服务的“暖心人”……特别是今年冬天新冠疫情复杂严峻，全国多地不断出现零星散发和局部聚集性疫情，社区防控压力也与日俱增。从地毯式排查、不厌其烦地一遍遍核实居民信息，到封闭管理，做好隔离人员的日常生活保障工作，再到全民核酸检测，挨家挨户通知居民、告知注意事项，你们“逆行身影”成为了这个冬天最美丽的风景线，你们的“再三叮嘱”是居民心中最动听的旋律。谢谢你，广大社区工作者，正因为你们的坚守与奉献，让我们相信来日可期，团圆将至。

看不清你的面容，

但你白衣胜雪的背影，

却是我今生见过的最美风景。

——致奋战一线的医务人员

他们是一群站在守护生命最前沿的“白衣战士”。发热门诊24小时的彻夜坚守，换来的是病人及时诊疗后的安心、放心;扫码、测温、登记的严格程序，换来的是就诊群众进出医院安全、有序。他们直面病毒，奋战一线，为生命保驾护航。支援武汉时，他们义无反顾、冲锋在前，用行动践行“若有战，召必应”的铮铮誓言;全民核酸检测时，他们全副武装入户检测，虽衣着不便、脚步沉重，但却从未影响到核酸检测的进度。从他们身上，我们看到了医务人员的坚守与奉献，看到了最崇高的精神追求，看到了生命至上、舍生忘死的抗疫精神。哪有什么岁月静好，只因有人负重前行。医务人员的守护是战胜疫情的最大支撑，向你们致敬!

Each year, people burn or cut down 143,000 square kilometers (55,000 square

miles) of the forest. People who burn or cut down trees do it for different

reasons: farmers cut down trees in order to get more fertilize lands to grow

rice or vegetables, and use the woods as fuel. Timber companies cut down trees

and turn them into furniture or paper productions. As to goal miners, they

remove the forests to find out whether there are goal underground.

However, many of us fail to realize that forests are the lungs of the

earth. When we cut down trees, we also push ourselves in to a dangerous

situation. That is the global warming. When you come to think about it, there

are only few ways to solve these negative effects: stop cutting down trees

blindly; try to find some clear energy that can replace oil and coal. But these

solutions can be impractical to some degreed.

Why trees can be so important to the whole nature? First of all, trees are

the habitat of many animals. When we cut down trees, we not only destroy

animals’ habitats but also ourselves. We just gradually destroy natural links.

The result is that many spices of animals and plants are dying out. Secondly,

cutting down trees cause global warming, to some degree. Naturalists compare

forest to human’s lungs. The forests absorb the carbon dioxide and other gas

that cause global warming, and then give off the oxygen that good for the human

beings and other living creatures. It’s refreshed the air as well as reduced the

noise. If the air quality is bad, people may die from cancers, or the new

diseases for which they have no immunity. Forests also play an important role in

the prevention of natural disasters. Warmer temperatures cause water to expand

and also create more water by melting polar ice caps. That’s to say, the nations

which near the ocean may have been flooded by the water. But the forests can

prevent water loss and soil erosion, and cool off the global temperatures. It’s

the key to keep the balance of the nature.

Sometimes people only care about money making; they don’t care about the

price we pay for the pollution. When the disaster is around the corner, we may

be afraid and frustrated. The earth, on which our economies have always been

based, is suddenly threatening our existence. All we hope that is this

overpopulated, over industrialized planet can carry on for a longer time. And

maybe, it’s time for us to realize that we should protect the earth, stop

cutting down trees blindly and madly.

What is art? When people think about this question, they will naturally

think about all kinds of musical instruments or the great paintings in the art

museums. Art seems to so far away from the ordinary people, but I don’t think

so. Art is everywhere. For example, the delicious food that is made by our

parents is the great art, and the value of the food is to bring people the great

joy when they have a taste of it. The scenery around us is the visible art, when

we appreciate it, our mood become eased. Art is something that brings people the

positive value for me, so art is around everybody. If we take time to slow down

our pace, then we can enjoy art from life and feel the comfortable

lifestyle.

We need to follow all kinds of public rules, such as the manner rules and

the traffic regulation. If we break the rules, then all the work will be out of

order and everybody will suffer the loss. But few people just ignore the rules

and waste other people’s time and money.

Chinese high speed train has won many praise from foreign people. The

trains always start off as the timetable and reach the destination on time. High

speed train is popular by the public by its speed and punctuality, but what if

someone breaks the traffic rule? Recently, a video got popular on the Internet.

A woman was stuck in the door of high speed train and the staffs tried to stop

her but failed. She said her husband was on the way and she wanted the train to

start off later. How ridiculous it was. How could she let all the passengers to

wait for her. Everybody’s time is precious.

Though the woman apologized after the policemen’s education, what she did

discomforts the public. The way she acted wasted the public’s time. It is our

duty to follow rules and keep the public in order.

“爆竹声中一岁除，春风送暖入屠苏。千门万户瞳瞳日，总把新桃换旧符。”这是一首千古传唱的好诗，每到过年时期，我和小伙伴们便开始吟诵这首喜气洋洋的诗，家乡的过年习俗也不由自主地脱口而出，我至今依然刻骨铭心。

大年三十吃团圆饭，欢天喜地过大年。好不容易到了晚上，大人们有的跳广场舞，有的嗑瓜子聊天，话说不完似的......我兴奋地在家里跑来跑去，抑制不住自己喜悦的心情。当我跑到阳台时，突然，烟花飞到天空，在一瞬间炸开了，有的像无数颗流星，有的像五光十色的花朵，还有的如同金色的太阳，把大地照得如同白昼一样，简直太美了!

我边看着烟花，边想着以前的传说。相传，早在几千年前，有种叫“年”的怪兽，每过三百六十五天，就跑到村里来偷吃人，这时，有位老人路过说：“‘年’最怕响声，红色和灯光。”人们就在春节的前一天，在门上贴上红纸，放鞭炮，打开灯光，不睡觉，到现在我们都会放鞭炮放烟花，我正想着传说，这时，窗外的烟花“嘭”地一声炸开了，我的脸也红了，不知是烟花映红，还是激动的涨红。

多么美的烟花啊!多么热闹的春节啊!我真希望这一刻能停留得久一些，再久一些......

Every day, we can see the figures of the volunteers. Actually, they have

formed a kind of scenery of the city. Some people hold that volunteering is

merely a waste of time, because the volunteers have no gains with pains.

However, I believe that doing voluntary is quite rewarding.

In the first place, we can put into practice what we have learnt before,

for instance, when we were asked by a foreigner about the way to some place, we

could practice our oral foreign language, it’s definitely a good opportunity to

express ourselves in a foreign language correctly and clearly.

In the second place, we could make a lot of new friends while we are

volunteering As a proverb says, “At home one relies on one’s parents and outside

on one’s friends”, so it is never a bad thing to have lots of friends.

Finally, helping others is a good way to make you feel happy and when you

help others solve a problem successful, you will feel fulfillment. In this

sense, we reap a bountiful spiritual harvest by doing voluntary work.

On the whole, we can benefit a lot by engaging ourselves in the voluntary

work. Therefore, I suggest those that have abundant spare time registering as

volunteers for the welfare for the public.

At present, there is a hot word in our life - "low carbon". For this new

friend, I have done a detailed understanding, the original, low carbon is to

reduce carbon dioxide emissions. Low carbon environmental protection, green

travel, in todays society, bike sharing is the top priority.

In 2017, shared bicycles have sprung up on the streets of Fuzhou with

colorful colors, including blue, orange and yellow Dressed up in the beautiful

streets of Fuzhou. It serves every citizen of Fuzhou and brings convenience to

us. Everyone is contributing to the environmental protection cause of Fuzhou.

This is the responsibility and obligation of Fuzhou citizens. I see the rapid

development of bike sharing. There are yellow cars, Moby bikes, and hello bikes

This aroused my curiosity, and I also wanted to experience it. Today, I took my

mothers mobile phone and couldnt wait to find a small yellow car. I turned on my

mobile phone, scanned the QR code of the bike sharing car, and input the

password. I only heard "didi" and the lock on the bike was opened. This

operation is really convenient. So my mom and I got on the bike sharing. We

enjoy the scenery on both sides of the road, talking and laughing all the way,

but also exercise. This is really a healthy and environmentally friendly way to

travel!

However, the good time is not long, bike sharing is facing unprecedented

disaster. Some are thrown into rivers, some are short of arms and legs, some are

locked in private Where are the qualities of these people? Is this the quality

that we Chinese should have? No, this is not the quality that we Chinese should

have! This small bike sharing is like a mirror, reflecting the quality of

Chinese people. The original intention of bike sharing is good, it can bring

convenience to the public, low-carbon environmental protection, green travel! I

hope you can maintain bike sharing together!

With the progress of society, peoples quality should be constantly

improved. Bike sharing is a good invention. Lets protect it together. Low carbon

and environmental protection. Starting from me, lets maintain a better tomorrow

with both hands. Lets make our sky bluer and our air cleaner!

In 2011, the greatest CEO of Apple company, Steve Jobs passed away. People

from all around the world felt pity for the loss of this great talent. They laid

down notes and wrote some comments on the blog to show their respect. Looked at

Steves lifetime, he did not finished college and started his career in the age.

Though he quit school, he would listen to another lesson that caught his

interest. He overcame the difficulty of being poor by earning money through

collecting bottles. His insistence and creativity brought him great success in

career, but later he got fired. He felt frustrated then he realized he could

start his another career. He bought an animation studio and now it is very

successful. The Pixar movie studio is popular around the world. Steves story

inspires the young people to fight for their dreams.

Since the financial crisis swept the world, the global economy has sunk into a severe recession. It’s hard to get through a day without hearing or reading news about the devastating effects of the crisis: A world of companies go bankrupt, millions of employees are laid off, high-return investment bubbles burst, and huge sums of loans can never be retrieved. Its impact on our daily life can be felt in all walks of life。

College students inevitably fall victim to this pervasive slump as well. On top of that, internships and job vacancies are reduced to the minimum as companies keep shrinking. New graduates find themselves hard to get a job, not to speak of a satisfactory one. What comes next? Poor students will be hard-pressed if they find student loans unavailable any more. As a result, some even cannot afford to continue their studies. Lastly, more students are probably out there anxiously looking for part-time jobs now that they have to help cover their expenses in this gloomy economy. Their innocence and eagerness might be taken advantage of by some malicious businesspeople, or even criminal gang。

In response to these threats, we students must act promptly and wisely. Since we definitely will be facing a competitive job market, it’s crucial that we submit high quality resumes. Therefore, we must commit more to our professional studies. Even do better, master more relevant job skills as a double security. Furthermore, apply for scholarships and grants, as these are still available and we don’t have to pay them back. As for the safety issues, trust our instinct – there’s no free lunch in this world. Anything that promises quick returns without much work is a sure trap. Stay alert and protect ourselves。
