钟南山英语作文【热门20篇】

People always attach the importance to the promise, they hate people who

break their promise. I remember once a time, my friend asked me to go to see the

movie with her, I said yes without hesitation. But on that day, I forgot about

the date, I just woke up late and then played computer games in my bedroom. My

friends called me, she asked why did I disappear, I said I was sleeping at home,

she became very angry, until then did I think about our date. I felt so sorry, I

break my promise for the first time, I realize I did the very bad thing. Even

though I apologized for many times, my friend was still angry with me. I learn

the lesson, promise is very important, we must keep it, other people will see

through our personality to decide what kind of person we are.

In the matter of courage we all have our limits. There never was a hero who

did not have his bounds. I suppose it may be said of Nelson and all the others

whose courage has been advertised that there came times in their lives when

their bravery knew it had come to its limit.

I have found mine a good many times. Sometimes this was expected--often it

was unexpected. I know a man who is not afraid to sleep with a rattle-snake, but

you could not get him to sleep with a safety-razor.

I never had the courage to talk across a long, narrow room. I should be at

the end of the room facing all the audience. If I attempt to talk across a room

I find myself turning this way and that, and thus at alternate periods I have

part of the audience behind me. You ought never to have any part of the audience

behind you; you never can tell what they are going to do.

Communicating with others is a big problem in daily life. Some people are

easy to talk to oters, but some others not. When you want to talk to someone,

firstly you should find some topics to talk about, but the topics should not

included the privacy,such as age, marriage or wage. Secondly, pay attention to

your attitude that do not make others feel uncomfortable. Comfort is the basic

of communication. Thirdly, pay attention to your body language. Body language

can transmit much information, such as your attitude, manners or something you

do not realize. Finally, focus on your pacing. Dont talk too fast or too

slow.

When asked about their opinion of career and family, people always respond differently. Some people deem it more important to pursue their career, while there are always other people who argue that family should be the number one in one’s life.

It goes without any question that career plays a key role in our life. In the very first place, career can give us an aim to live on. Without career, much of our living time will be certainly wasted. What’s more, career can provide us with a means to live on. Most of the people earn their income from a job. On the other hand, family is also an indispensable part of life, as many people will admit. Family is always regarded as a place where we can escape from troubles in life. In addition, we can obtain a sense of belonging to from family. Without it, anyone will feel lonely and desperate.

In my opinion, career and family are not in opposition to each other. Rather, they can enhance each other so that one’s life can become better and better. Therefore, it’s not a choice between right and wrong, but one between ideal and practical.

在谈到自己的事业和家庭的意见要求，人总是有不同的反应。有些人认为这更重要的是追求自己的事业，而总有那么谁认为家庭应该是一个人的生活的人数1人。

毫无疑问，任何事业在我们生活中起着关键作用。在第一个地方，可以给我们一个职业生涯的目标是生活。没有职业生涯中，大部分时间我们的生活一定会被浪费。更重要的是，职业生涯可以提供一种手段，对我们的生活。大多数人从工作中赚取的收入。另一方面，家庭也是生活中不可缺少的一部分，因为很多人会承认。家庭一直被认为是一个地方，我们可以摆脱生活中的麻烦。此外，我们可以得到一个属于家庭的感觉。没有它，人会感到孤独和绝望。

在我看来，职业和家庭是不反对对方。相反，它们可以加强彼此，使自己的生活能够越来越好。因此，它不是对与错之间的选择，但理想和现实之间的一个。

After a while, finally it was my turn, I skipping took to the podium, picked up a toothpick, gently thorn under a mass of glutinous rice, dip in a little bit of sugar, healthy-looking and happily. When I got back to my seat, I had a mouthful of food, and I put it in my mouth. It was so sweet. Finally, it is delicious to lick the white sugar on my lips.

You thorn, I see, the time is finally arrived, just put the hand inside a stretch, alas! I was struck by someones toothpick, and I was like an ant on a hot pot. Only the last zongzi was left, and everyone was so crowded that the dumplings were torn apart by us, and the teacher was busy and busy. When I was disappointed, tian teacher suddenly turned into my mouth was a mass of rice dumplings, joyous and pleased, I happily returned to the seat, whilst placing a hand over your mouth cant say how sweet in my heart. When the dumplings were finished, some students returned to their seats disappointed. Some students were so happy that they took a lot of dumplings.

This happy Dragon Boat Festival is really unforgettable to me.

Because the Palace Museum is a place of five thousand years of brilliance

and ancient culture, so he has long been a tourist attraction in my heart, and

this summer vacation I have finally made a dream come true.

In Beijing I will ride my father and mother went to the tiananmen square,

across tiananmen square, the meridian gate of the world-famous greeted the hall

of supreme harmony, the hall of supreme harmony majestic, magnificent, colorful

glazed tile, such as a long arranged very neat. Curved corner with a monster,

four up the eaves of the cock appear grand hall of supreme harmony, to the hall

of supreme harmony, seventy-two large andalusite carved dragon painted chicken

shows the architecture of the feudal monarchy. The golden roof reflects the

majesty and status of the ancient Chinese emperors. The great hall looked solemn

and solemn, but the beauty of the appearance was so monotonous and heavy that I

was in vain. I dont know why I feel as if a group of puppets are standing

respectfully on either side of the house. Incense sticks up in the incense

burner, and the emperor sits high in the temple. The Palace Museum, a symbol of

the ancient kingship, has been invaded by a brick and a brick. It is far from

the palace of Buckingham Palace.

In the afternoon, we in addition to the front door, look back at taihe

light standing in tiananmen square, this magnificent buildings, so the layout of

the orderly, so solemn, not amazing, hope this trip to the Forbidden City will

become my eternal memory.

My school life is very common. I get up at six o’clock every morningfrom

teacher says health is themost important thing. After running I have to do

morning exercises on theplayground. Then I can have breakfast. Having breakfast,

I need to have morningreading. Oh, I almost forget that all of the students have

to do some cleaningbefore breakfast. There come the various classes. Then noon

comes. Havinglunch, I will go to sleep. I often read twenty minutes before I

fall asleep. I haveclass in the afternoon. And I still have classes at night.

It’s boring, right? ButI have got used to it and enjoy myself at school.

I’m neither interested in sports nor good at it. But except swimming. I can

swim since I was a baby. My mother tells me that she let me swim in the water

with a life-buoy when I was 20 days old. And then I can swim gradually. When I

grow up, I like swimming very much. I swim all the year round. Swimming in

summer makes me feel comfortable to lower my temperature. While winter swimming

makes me feel excited and achievability. In general, swimming keeps me fit in

both physical and mental. Whenever I feel upset, I would go swimming and then I

would be full of energy and feel relax. Besides I believe it is due to swimming

that I’m so thin. Who wants to lose weight, join me. We can make more friends in

swimming. Oh, I couldn’t wait to swim now. But it is ten o’clock in the evening.

I have to go to sleep. Good night everyone.

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.

"Qingming Festival is one of the most important traditional festival China.

It is not only the people pay homage to their ancestors, cherish the memory of

their ancestors Festival, is also the Chinese nations link to find ones

origin, is a hiking outing, close to nature, protecting the new spring

ceremony."

As an important content of the festival Ching Ming Festival sacrifice,

outing custom comes from the cold food festival, Shangsi festival. The cold food

festival and the understanding of the nature of the. In China, cold food after

the rebirth of the new fire is a kind of new transition ceremony, said the

seasonal alternation information, a symbol of starting the new season, new hope,

new life, new cycle. Then there is the "thanksgiving" means, more emphasis on

the "past" Remembrance and gratitude. Cold food observance ban fire cold food

festival tomb sweeping outing travel, take new fire. Before the Tang Dynasty,

cold and clarity is the two successive but the theme of different festivals, the

former Qiu Xin Memorial nostalgia, the nursing students; Yin and Yang, a breath

of life, the two have close relationship with the. Fire ban is for fire,

sacrifice to the Archilife dead, it is cold and clear the inherent cultural

association. Tang Xuanzong, the court had to order in the form of folk customs

in the Ching Ming Festival fixed sweep the tombs of the cold food festival,

Hanshi and Qingming is closely connected with in time, cold food festival and

Qingming associated with early, sweep the tombs from the extended to the

Qingming cold food.

So many children take what their parents do for them for granted, they

haven’t realized the meaning of being grateful. So they always get angry with

their parents, because they don’t get what they want. According to the news that

a little girl went out of the house and refused to go home because her parents

did not give her enough pocket money. I was so shocked to hear it, I would never

ask much from my parents, because I knew they were not easy to make a living and

I am always feel so thankful for what they offer me. Even the one who gives me a

hand when I am in need, I would remember him and when I have the chance, I will

return. A grateful heart makes us a kind person and create a harmonious

environment.

When it comes to online shopping, different people holds different ideas

towards it. Some people seem extremely enjoy the way of buying things online

because they feel online shopping is so convenient. Some just don’t believe that

they can buy good quality commodities from Internet. As far as I’m concerned, I

think online shopping creates lots of benefits to people.

Firstly, buying things online is a way of saving time. Compared with the

traditional way of shopping, we have no need to go out to pick up our favorite

goods from store to store. Just a click, we can have things in our shopping cart

and just wait for the goods to be delivered to us. To this extent, not only we

can save the time of finding things from store to store but we don’t need to

spend time on transportation. Thus, we can save lots of time to enjoy fun.

Secondly, buying things online can save our money. People buy commodities

by Internet not only because it saves us time, but also, we can save lots of

money. It is often seen that some people just go to the physical store to check

out the commodities they want to buy and then they would search for their

favorite commodities online and take the order. People do this just because they

know that online goods are usually cheaper than the goods displayed in shop

window because online shop have no need to pay the rent. So, people are more

inclined to buying things from online store.

Thirdly, convenience is the last but not least thing of shopping online.

Since we can buy things online, there is no need to go out to look for things we

want to buy. What we need to do is to simply sit before our computer, search for

things we want to buy, click our favorite thing and then pay our order by our

bank card. And then, you just need to wait for your goods to be delivered to

your home.

In conclusion, shopping online is a convenient, time-saving and money

saving way of buying things. Therefore, we can benefit a lot from shopping

online. That’s the reason of why shopping online has developed faster and faster

in recent years.

When it comes to success, different people have different opinions about

what makes it come true. Some people regard hard-working as an essential quality

to success while others believe being clever would lead to success. From my

point of view, I think perseverance and hard-working are indispensable for those

who want to make an achievement.

Firstly, perseverance let people step closely towards success. Most people

want to make a big difference to prove their value. People who set their goal

and keep moving would make their dream come true. However, there are some people

who set their goal but they stop at the difficulty would fail in the end. I

think the difference between success and failure is perseverance. If we have

perseverance, even if we are not clever, we will make a great difference, but if

we not, we are doomed to lose. As we all know, Edison is a great inventor in the

world. However, before he invented the bulb, he kept trying for tens of

thousands of times to find a suitable wire. Let us imagine, if he gave up at the

999th, then how he couldn’t become so successful. So, I strongly believe that

perseverance produces success.

Secondly, there is also a kind of people who are born with cleverness, I

think they are lucky. Nevertheless, if they don’t make a hard work on their way

to their goal, they, absolutely, will become loser. Whether we are gifted for

intelligent, we must be hard-working so as to success. I regard hard-working as

an efficient approach to be successful because I believe ‘pains and gains’. As

for those who do not make great efforts on work, failure follows. In old times,

there is a clever boy who can make excellent poem when he can talk. When his

father found the little child’s cleverness, he just let the child make poems to

show around while never let the boy learned anything. When the boy grew up,

people forgot him because he lost the ability to compose poems and became

ordinary as others. From this matter, we can see that only by hard-working can

we get knowledge and make a good future.

Anyway, I think perseverance and hard-working are both important in our way

to success for they enhance us and produce success.

爱国心是通过实践而养成的一种眷恋故乡的感情。

Patriotism is a kind of nostalgic feeling formed through practice.

岁末年初，正当人们准备欢度春节之际，新型冠状病毒感染的肺炎疫情悄然而来，一场阻击病毒疫情的战斗也随之打响。在疫情爆发和防控危险时刻，总有一些我们不知道的无名英雄，他们以“逆行”的姿态为我们筑起一道坚固的“防护墙”，他们在打一场没有硝烟的疫情战，是一条永无退路并且必胜阻击战。他们，就是这个时代的最美逆行者。

Novel coronavirus infection is coming quietly at the beginning of the year,

just as people are ready to celebrate the Spring Festival. A battle against the

virus has also started. At the time of outbreak and prevention and control,

there are always some unknown heroes who build a solid "protective wall" for us

in a "retrograde" attitude. They are fighting an epidemic war without smoke of

gunpowder, which is a never-ending and inevitable resistance war. They are the

most beautiful rebels of this era.

抗击疫情，他是我们的“定海神针”

To fight against the epidemic, he is our "Dinghaishenzhen needle"

1月18日，钟南山院士从广州赶往武汉。1月19日从武汉又赶往北京，凌晨两点才睡觉。1月20日全国电视电话会议新闻发布会，媒体直播连线又是忙到深夜。实际上，钟南山院士一直活跃在科学前线，在来武汉之前，他也没有退休、没有安逸。他曾说：“医院是战场，作为战士，我们不冲上去谁上去?”他是无双国士，更是定海神针!根本就没有什么岁月静好，只是他和他的战友们冒着牺牲的危险替我们负重前行。

On January 18, academician Zhong Nanshan rushed to Wuhan from Guangzhou.

From Wuhan to Beijing on January 19, I went to bed at two oclock in the

morning. On January 20, at the national teleconference press conference, the

live media connection was busy late into the night. In fact, academician Zhong

Nanshan has been active in the front line of science. Before he came to Wuhan,

he didnt retire and have no comfort. He once said: "the hospital is the

battlefield, as soldiers, who dont we rush to?" he is the unparalleled

national, but also the sea god needle! There is no time to be quiet, but he and

his comrades risked the risk of sacrifice to carry forward for us.

抗击疫情，她是我们的“铁娘子”

To fight the epidemic, she is our "Iron Lady"

严丽，她是急诊科医护团队眼里的“铁娘子”。武汉发现新型肺炎后病人骤增，急诊科下夜班后，严丽还要去支援发热门诊，白天黑夜连轴转。”1月20日，严丽带着丈夫和孩子来到机场。临近登机时她却改变主意，决定重回医院，与同事们一起继续抗击新型肺炎，“去机场的路上心就慌慌的，回到医院内心才平静。”孩子不理解，抱着我哭，说我从来就没有兑现过承诺。严丽说，“不是觉得自己高尚，只觉得一线医护人员紧缺，自己一辈子没当过逃兵。这一次也不能离开。”哪有什么白衣天使，只不过是一群孩子换了身衣服，学着前辈的样子和死神抢人。

Yan Li, she is the "Iron Lady" in the eyes of the emergency department

medical team. After the discovery of new pneumonia in Wuhan, the number of

patients increased dramatically. After the night shift in the emergency

department, Yan Li had to go to the fever clinic to support the fever clinic.

She worked day and night. " On January 20, Yan Li arrived at the airport with

her husband and children. She changed her mind and decided to go back to the

hospital to fight against the new pneumonia with her colleagues The child didnt

understand, hugged me and cried, saying that I had never fulfilled my promise.

Yan Li said, "I dont think Im noble. I just feel that there is a shortage of

front-line medical staff. I havent been a deserter in my life. I cant leave

this time. " There is no angel in white, but a group of children changed their

clothes and learned how to rob people with death.

“苟利国家生死以，岂因祸福避趋之”。防疫战场上医护人员那一张张印着红指印的请战书;新闻里笑容腼腆的女护士朴素的语言：“只要穿上白大褂就不害怕了......”武汉医生与家人隔离，白发老母亲隔门叮嘱时的眼泪;除夕夜，各地医护人员紧急集结赴武汉和家人告别时的拥抱;大年三十返岗生产口罩的工人;《爱是桥梁》，春晚的节目为武汉而改变......

"For the sake of the countrys life and death, do you avoid it because of

misfortunes and blessings?". On the battlefield of epidemic prevention, the

doctors letter of invitation printed with red fingers; the plain language of

the female nurse with a shy smile in the news: "as long as you put on the white

coat, you will not be afraid..." Wuhan doctors are separated from their

families, and the tears of the old mother with white hair when she is told by

the door; on New Years Eve, medical staff from all over the world gather to

Wuhan to say goodbye to their families; those who return to work on the 30th of

the new year to produce masks Workers; love is a bridge, the program of Spring

Festival Gala changes for Wuhan

每当看到电视上那些一身白色“戎装”，战斗在防疫第一线的白衣战士,我就充满虔敬,他们视疫情为敌情,把医院当战场,在没有硝烟的战斗中舍生忘死,以大无畏的精神和钢铁般的意志,谱写了一曲曲光辉壮丽的人生赞歌。

Every time I see those white soldiers in military uniform fighting in the

front line of epidemic prevention on TV, I am full of piety. They regard the

epidemic situation as the enemy, regard the hospital as the battlefield, and

forget to die in the fight without gunpowder smoke. With the spirit of

fearlessness and the will of steel, they compose a glorious and magnificent hymn

of life.

哪有什么岁月静好，不过是有人替你负重前行。只要万众一心，就没有翻不过去的山;只要众志成城，就没有过不去的坎。我们要坚定信心从自身做起。长大之后我们替你们继续前行!武汉加油!

There is no time to be quiet, but someone is carrying the weight for you.

As long as all people are united, there will be no mountains that cannot be

turned over; as long as all people are united, there will be no barriers that

cannot be crossed. We need to be confident and start with ourselves. After

growing up, we will continue to move forward for you! Come on, Wuhan!

请相信待春暖花开之时，我们都可以走上街头，不用口罩，繁华与共，共享春光灿烂!

Please believe that when spring comes, we can all go to the streets,

without masks, and share the bright spring!

Every person needs sleep everyday. But with the high development of

society, most people have more and more things to do and have less time to

sleep. As a result, many people are lack of sleep. For a short time, they may

not realize the bad side of it, but it will bring something bad for them after a

long term. First of all, lack of sleep will do harm to people’s look. If they do

not sleep enough, they will get black eyes and bad skin easily, which will make

people look no so beautiful. Secondly, lack of sleep is bad for the spiritual

outlook. A person who lacking of sleep always looks tired and has no power to do

things. Last, not enough sleep for a long time will have bad influence of

thought. They always can’t be active in mind.

had been cracked and the screen had been scratched.

In view of this, I have decided to make a formal complaint against your

delivery service. I sincerely hope that you will replace this computer as soon

as possible. If this is not possible, I will have no alternative but to insist

on a full refund.

I would appreciate anything you can do to help us in this matter.

Yours truly,

"Green" the eternal topic, let us better to understand the importance of

environmental protection.

Green environmental protection is to make us live a happy life in a clean

environment, however, the environment around us in a worse if we dont alarm,

then, our motherland will be a mess in our hands! Green environmental protection

starts from me. My dad used to drive his car to work, listen to my advice, to

protect the environment, he ride a bike from now on, he thought that not only

the exercise of his body, also for the green environmental protection.

My mother began to contribute to the green environmental protection. Before

she went to vegetable market to buy food, she used plastic bags, a village green

environmental protection propaganda on TV, she understood the green

environmental protection is sustainable, in order to we can have a better

environment. In order to we live healthier lives, so mom from that moment on,

every day go to vegetable market with the own basket, instead of plastic

bags.

As a new era of junior middle school students, and I will response to the

green environmental protection call for, I had at school are all use one off

chopsticks, but now I can bring their own chopsticks to school. I think, though

this is a small matter, but I do my responsibility.

Happiness of life to let China land everyone be permeated with happy smile,

rich products, long history, noble quality, the plot environment. Nowadays, the

environment is polluted, the green environmental protection starts from me, let

us together to protect the environment!

Since the childhood, I the most favorite thing to do is to study, I have

read many books, there is "always cuckoo", "wu DiuDiuDe adventure", "little fox

buy gloves", and "the window of small doug"...

There are many benefits for me to read. Can not only help me when doing the

reading, a better understanding of the meaning of the article, and can be better

for me to apply my good word, we can also let us learn a lot, understand a lot

of sense. Read to make us happy! Reading let us have more laughter!

Among them, I most like to watch "Madame Curie". Madame Curie is like us,

since the childhood like intimate contact with nature, Copernicus was her model.

Selfless great simplicity, humility, her character, persistent, hard work,

perseverance, indomitable spirit, she found two elements, polonium and radium,

she won two Nobel prizes. Who can imagine, she is the "mother", radium gave

great contribution to the wealth to the world, he even do research, could not

afford to 1 gram of radium. As a great woman, she won the sympathy of the people

of the world, support and respect.

Read the "Madame Curie", I think I should learn from her, learning her not

to difficultly lowers the head, she determined the indomitable spirit of hard.

Im going to study hard, grow up to do a scientist like her.

Let us together, can read, read good books, good books!

The environment of the city is getting worse and worse today. There are wastes, air pollution and so on. What can we do to save our city? About the wastes, we should sort the wastes, to see if they can be recycle used; use the reusable shopping bag instead of the plastic bags. About the air pollution, we should go to school on foot or by bike; we should also ask our family not to use car as much as possible, take the subway or bus instead. I hope everyone can see the environment problem and do the best to save our city.

如今城市的环境变得越来越糟。有垃圾和空气污染等问题。我们应该如何保护我们的城市?关于垃圾，我们应该进行垃圾分类，看看它们是不是可以回收利用;使用环保购物袋来代替塑料袋。关于空气污染，我们应该走路或者骑自行车去学校;我们还应该要求家人尽量少使用汽车，用地铁或者公交车代替。我希望每个人都能看到环境问题，尽量来拯救我们的城市。
