With the development of e-commerce, shopping online becomes a new way of

shopping which is getting more and more popular. Many citizens are likely to

shop through internet nowadays.

Generally speaking, shopping online offers lots of advantages with its

convenience the most prominent. There are many commodities on the internet where

you can search whatever you want. Besides, you just click the mouse can you get

all information you want, so that you don’t have to go to the shop personally.

In addtition, the commodities on the Internet is usually cheaper than the stores

which can save much money.

However, everything has two sides. You can not see the products or check

their qualities and some of the sellers on the Internet is not so honest. And,

for those who enjoys shopping around different stores, shopping online perhaps

will make them bored.

In my opinion, shopping online has more advantages than disadvantages, and

with the improvement of e-commerce, there will be more people to shop on the

Internet.

China had cause for a double celebration on Saturday after winning their

first ever swimming gold medal as well as setting a new world record in the

womens 400m medley.

Sun Yang sealed a place in Chinas Olympic history with an impressive swim

in the 400m freestyle final that was only 0.07 seconds off the world record to

take gold.

Defending Olympic champion Park Ta-Hwan was leading at the final turn, but

the 20-year-old Sun surged past his South Korean rival in the final length to

seal a place in Chinese Olympic history.

"The feeling is very nice, its beautiful. Its a big dream come true for

me," said Sun.

"Because its the Olympic Games, I felt a little bit nervous at the start,

and then at the end, I felt that I could get a medal."

Twenty minutes after Yang won Chinas maiden gold medal, 16-year-old Ye

Shiwen triumphed in the womens 400m medley, as well as breaking the world

record set in Beijing four years ago.

Ye rounded off a sparkling day in the pool for China as she claimed the

title with a breathtaking final lap of 28.93 seconds.

"I thought at the 200 meters that the race was lost, but then I realized I

was in the top two or three and I was confident I could win on the last leg,"

said Ye.

"I dreamed of winning the gold medal, but I never ever expected to break a

world record, Im overwhelmed."

These are lots of books in our daily life. Some are about history, some are novels, and some are even about the dream in the future. I think its useful to read stories, because it can be used sometimes. Once, there was a very difficult question in an important history exam history, which wasnt mentioned in our history books, even our teacher has never told us about it. But I remembered clearly that I had read it in a history story, so I answered the question without difficulty and became the only student in our class who answered the question correctly. In my view, its useful to read stories.

Dear manager,

I write this letter to you to make some complaints about the computer I

bought in your store yesterday afternoon. There s something wrong with it. That

makes me extremely unhappy.

The computer cannot be properly shut down when I got it back to the office.

When I click the shutdown button, it seems that the machine gives no response.

And Im so annoyed with it.

Its obvious that you didn t carefully examine the machine before you sold

it. I think your store should take full responsibility for selling me the

defective machine. I insist that you give me a satisfactory reply. I do want you

to give back my money as soon as possible.

Sincerely yours,

Jack

holidays to travel. Traveling is my favorite and it can reduce my pressure. It’s

good for my life. Therefore, I hope traveling can be a part of my future

life.

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!

Olympic Games hold every four years and I like to watch the matches so

much. People always pay much attention to the champions, while for me, the

inspiring players are easier to catch my attention. Though some players do not

get the prize, they deserve applause as the champions have. I remembered that in

the Beijing Olympics, in women’s 100-meter-race, a girl looked different from

other athletes, because she worn scarf and was from Afghanistan. She lagged much

behind other athletes, but she still got the intense applause. She showed to the

world that Afghan women could join this big event. Her insistence helped her to

come to the world stage.

As it’s known to all, China is popular for its emperor of bicycles. This is

because our country is still a developing country and few people can afford

private cars. The demand for a means of transport is met by making millions of

bicycles available.

Riding a bicycle has a lot of advantages over driving a car. First, it is a

physical exercise to ride a bicycle. In contrast, sitting in the car, one tends

to gain weight. Besides, it is much more economical to ride a bike than drive a

car. On the one hand, the only fee a bike-rider has to pay is the annual tax.

However, the annual fees for a car are costly. On the other hand, a bike neednt

be equipped with a parking lot, but a car must. Most important of all, it is

beneficial to the environment to ride a bicycle because the bike doesnt consume

petrol; it is a pollution-free transport. In contrast, the exhaust released by

the car is harmful to the environment.

Since China is a developing country with a large population, bicycles will

still be the most popular means of transport in China for quite a long time.

Most people will still ride bicycles to go to work or to school. The emperor

country of bicycles will remain for at least dozens of years.

The end of the term is coming soon. All the students are preparing for the

final exam. Some students want to get the high mark by playing some tricks.

There is no meaning to do this. Honesty is very important, because it decides

what kind of person we will be. So we should behave ourselves well and our

parents will be proud of us.

Many years ago, I saw a science fiction film, which described a future

world. The way people lived was very different. They could drive cars in the

sky. Everything in the future world was so convenient. Since then, I was always

curious about how the future world would become. The fling cars seemed so

ridiculous for now, but thinking about more than 100 years ago, people never

thought about flying in the sky, but now we could take planes and traveled

around the world. Everything was possible. Whats more, the development of

technology is so fast that the world changes so much every ten years. Nowadays,

people can pay the bill online. No matter where they go, a cell phone can solve

most problems. I believe that future transportation will be much efficient and

will surprise us all.

Social morality is an important part of our life that reflects the degree

of civilization of our country. Generally speaking, social morality contains

many aspects. For example, civility, which requires people behave in a becoming

manner and be friendly to others. Be ready to help others telling us that give a

hand to those who need help. When we help others, we can get gratification as

well. Just as the old saying goes, “Roses given, fragrance in hand.” Besides,

respecting the old and cherishing the young, protecting the environment,

observing law and discipline are also included in social morality. Observe

social morality is the basic requirement to a man of being moral, which has

positive effects that keep our society stable and harmonious. As a member of our

society, we should keep these disciplines and requirements in mind, so that act

as a moral people.

What is a good eating habit? In my opinion, a good eating habit is related

to eat healthily and regularly. To say it simply, Xiao Ming has breakfast about

7:30a.m. to 9:00a.m. every morning and lunch at noon. He also has dinner about

6:30p.m. to 7:30p.m in the evening. What he eats is healthy food, such as, meat,

vegetable, fruit, egg, milk and so on. He would not have some snacks for a meal.

He also would not eat and drink too much or eat nothing. Xiao Ming sets a good

example to have a good eating habit.

Its beyond reproach that we will come across all kinds of difficulties and

challenges in our life time .Some will be subjected to frequent sadness .Some

will lose their way to move on .Thus,only when we equip ourselves with hope and

courage can we finally succeed in the uncertain future.

Forrest Gump showed so great courage in the movie that he touched me a lot

. For one thing,no matter when and where Jenny got into trouble ,Forrest Gump

would bring her out of it without thinking how dangerous the situation would be

.Maybe we should all fell ashamed that we love ourselves more than we love love

,but Forrest showed great courage in love .For another,Forrest gump risked his

life to save Bubba in the war.Its courage that helped Forrest gain a series of

honor after war .Forrest Gump is beautiful for his perseverance and touches

others with his courage.

A person cant do without courage in terms of love and friendship ,let alone

life . A weak person may avoid the difficulties ,but a person with courage will

face up to it head-on. Therefore,letequip ourselves with great courage.

Since we were born, we are meant to face the stage of study and work until

we retire, which seems everybody does the same thing in their life. They start

to wonder about the meaning of life. In my opinion, the meaning of life lies in

study and finding the right place.

Study comes first for human being. Since we learn the knowledge, we get to

know about the world. The more we learn, the more we want to search for the

unknown knowledge. The world is beautiful because of diversity, and there are so

many amazing scenery waiting for us to discover. At the process of searching the

knowledge, we also become mature and have our own thinking.

Finding the place in the world is the basic task for us. The purpose of

knowledge is to master some skills, so as to get accustomed to the world and

know what we want to do and what we can bring to the world. The value we create

can bring happiness to people we love and make a contribution to the world.

Life is short, but we keep searching all the time.

Its so convenient and interesting to join a tourist group. When you travel

with a tourist group, you don’t need to book plane and train tickets, and you

dont have to care about where to live and what to eat either, because the

travel agency will arrange everything for you. All you need to do is to follow

the tour guides. They will take you to all the places of interest. They will

tell you stories about the interesting places and help you to learn local

culture. This is called a package tour.

A cruise trip is so comfortable and relaxing. You travel on a large sea

cruiser and enjoy the beautiful scenery. When you come up to a nice place, you

can get off the cruiser and visit there. When you are on board, you can lie on

the deck, watching the blue sky, the white cloud and the bright sun, and you

will be free from stress. Besides, there are so many nice activities on the

cruise. For example, you can watch movies; you can see concerts; you can go

swimming in the swimming pool; you can play cards; you can play golf; you can

watch wonderful performances; and you can also attend dancing parties. Nothing

could be more wonderful and relaxing.

Nowadays, backpacking tour has become so popular. Its not just a low-cost

travel for budget travelers, but also a nice entertainment. When you have a

backpacking tour, you can use public transportations like buses and subways and

stay in hostels instead of big hotels, which can save you a lot of money. Today,

this kind of travel is especially popular with young people, because they can

discover the interesting places and know more about the local cultures by

themselves. Its so exciting.

If you want to have a better understanding of a place, you can have a slow

travel. When you have a slow travel, you had better spend at least one week

living in one place, stay with a local family and visit interesting sites near

your living instead of rushing around for a long day to see the must-sees. In

this way, you can make more local friends, taste local food, and know the local

traditions and customs deeper. Only so can you become more knowledgeable and

widen your experience.

It depends on your need to choose the way you want to travel.

considred as a new start for the future, a wonderful conclusion for passed a

opportunity to everybody who wants to share the enjoyment with his or her

family. The relaxing conversation and jokes are around the rooms with the warm

atmosphere in the chill winter night.

There are a lot of traditions of the eve inherited for generations. But,

now more and more new fashions introduced into this eve and even replaced the

old traditions. More and more people are glad to have the dinner in the

restaurants instead of cooking and having at home. However, no matter what it

is, a harmouious and peaceful night is the favorite of everybody here.

The Duanwu Festival, which is also called the Dragon Boat Festival, is an

ancient Chinese traditional festival, celebrated on the fifth day of the fifth

lunar month. For thousands of years, various celebrating activities are held all

around the country. Eating zongzi and racing dragon boats are the most pertinent

ones, which are said to be in memory of Qu Yuan, a great poet. In some places,

people spread realgar wine on the children in the hope of protecting them from

the evil spirits. Many people consider May as an especially dangerous time for

diseases in a year, and therefore they hang moxa and calamus and things like

that around the doors to ward off evil and diseases and pray for good luck.
