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.

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.

If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

上个星期日我和爸爸一起去钓鱼。我们发现水太脏了，我们几乎不能在它的鱼。

沿着这条河的许多工厂总是把废水和垃圾倒进河里，使河水受到污染。这样，河里的大部分鱼都被杀死了。

如果这个国家的河水都被污染了，水里就不存在生物。我们都知道，环境污染对生物和人类都有很大的危害。现在越来越多的人开始意识到这个问题有多严重。我国政府正在尽最大努力采取措施打击污染。我们期望在每一条河流中的水将在长时间内变得更清洁，更清洁。

我们很幸福，因为我们住在一个美丽的地方，可是，随着人类的经济需求，许多人为了一己私利无限的开发利用，让我们这个曾经非常美丽的地方，被严重污染了！甚至因为人类的开发，许许多多的动物在近期灭绝了！

大家还曾记的地球的那几次灭绝吗？不说前几次，因为那是自然因素造成的，而近期的是吗？不是？是人类自己造成的？就那孤独乔治做例子，本来象龟有很多，但因为人类的滥捕滥杀，导致象龟只剩下一只了！而孤独乔治的功能退化它的蛋也不能孵化。我们人类只能眼睁睁的看着象龟一族灭绝！这就是滥捕滥杀的后果！我们以后不能这样做，更不能容忍别人这样做！

想要保护生态环境，一定要从自己做起，要用日常行动来影响他人。保护生态环境就可以在日常生活中见到。比如：出去购物我们可以带环保袋，减少使用塑料袋，因为塑料袋危害很大，大量集留会造成白色污染，破坏生态环境循环。所以，要尽量不使用塑料袋。家中还可以一水多用、倡步行、骑自行车…保护生态，从生活中做，是非常简单的。

为了未来，为了子孙后代，就让我们从现在开始，为保护环境而出发，为保护环境而奋斗吧！

In my memory, though my hometown is a small village, it is very beautiful. When I was small, I liked to caught fish in the river, the water was so clean that I could see the fish. As I miss my hometown so much, last week, I went back to my hometown, I found the place in my memory was not like what it was. The trees were not that numerous, the roads became bigger, while there was less place for the river, I saw some dead fish in the river, the water was dirty, the river pollution was so serious! I couldn’t believe it, the beautiful hometown was destroyed by the pollution, it is people’s ambition results in it, they chase for the profit at the cost of polluting the environment. I wish people can pay attention to protect the environment, they are saving themselves, too.

在我的记忆中，虽然我的家乡是个小城镇，但是很美丽。当我还小的时候，我喜欢在河里抓鱼，河水是如此的干净以至于我能看到河里的鱼。由于抵挡不住对家乡的思念，上周，我回到了家乡，我发现我记忆中的城市再也不是它原来的样子了。树没以前的多，道路变得宽阔，然而河道却变得窄些了，我看到河中有一些死掉的鱼，河水是如此的脏，河流污染是如此的严重!我无法相信眼前的一切，美丽的家乡被污染给破坏了，人们的贪念导致了这个结果，他们为了追求利益，不惜以牺牲环境为代价。我希望人们能注意保护环境，这也是在保护他们自己。

Dear Tim,

With Spring Festival drawing near, I’d like to invite you to my home to experience the festival.

When you come, we can enjoy traditional Chinese food together, and then put up Spring Festival couplets. As a traditional custom, the couplets are always posted on the door of a house. Written on red paper, a couplet is composed of two lines of poetry, which rhyme with each other. Not only do the couplets add some joyous atmosphere to the festival, but also they express people’s wishes for a better life.

I would appreciate it if you could accept my invitation. Looking forward to your coming.

Yours,

Li Hua

The Dragon Boat Festival is one of the most popular traditional festivals

celebrated in China, which is on the fifth of the fifth lunar month, also known

as Duanwu Festival. It’s said that it is to commemorate the death of a Chinese

patriotic poet, Qu Yuan, who was snared by corrupt officials in ancient China

and finally committed suicide by drowning himself in the Miluo River to protest

against them.

The traditions and customs held on this festival differ from place to

place, but there are some common in them. First, the most famous and great

tradition is holding Dragon Boat races, which are held by fishermen’s attempt to

protect Qu Yuan’s body against attacking by fishes and other animals in the

river by beating drums and row the dragon shaped boat. Nowadays dragon boat

races have been an annual popular sport activity among people. In addition,

making and eating Zongzi—a dumpling made of glutinous rice and wrapped in bamboo

or reed leaves—is also a popular custom during this day. It can be made by many

kinds of stuffing. What’s more, hanging herbs on the front door, drinking

realgar wine and pasting up picture of Zhongkui—a mythic guardian figure in

ancient china—are also popular during the festival, which are mean to protect

people from evil and disease.

These customs and traditions have been changed a little in recent years,

but they still make contribution to the spread and inheritance of Chinese

culture.

I used to receive gifts like a basketball, a swatch or a CD. But the gift

I’m looking forward to is a bicycle though I can’t ride it now. How I want to

learn it well so that I can ride anywhere I want to go! Every morning, it is my

father who always drives me to school in all kinds of weather. Especially in the

past few days, he has worked hard until midnight. If I ride my own bicycle to

school, he will be able to sleep a little longer and work a bit harder. I hope

my dream of owning a bicycle will be realized in the shortest possible time.

Happy Mid-autumn Day

Today is Mid-autumn Day. I have a big meal at home with my parents and

relatives. This is an important festival， so my mother was busy with preparing

the dinner from morning. She bought a lot of foods for the dinner. We ate the

dinner at 5：30 p.m.. The dinner was very delicious. I was so full. After dinner，

we went to theHongTingParkto enjoy the glorious full moon. There were many

people in the park.We talked to each other and strangers. Of course， the moon

cake was essential. We had a great night there.

今天是中秋节，我同父母和亲戚一起吃了一顿大餐。这是一个重要的节日，所以我妈妈从早到晚都在忙着准备晚饭。她买了很多的食物做晚餐。我们傍晚五点半吃晚饭，晚饭很好吃，我吃得很饱。晚饭过后，我么去红亭公园赏满月。公园里有很多人，不管认识与否，我们互相交谈。当然，月饼是必不可少的。我们在那度过了愉快的夜晚。

China, as a developing country, has a large gap compared with developed

countries. If we want to catch up with and even surpass the developed ones,

education seems important and should be given the first priority. Besides,

education seems the same important to individuals.

In modern time, when science and technology are making great progress, the

education of the work force is the most important. Moreover, many of the success

in advanced countries have demonstrated that a nations prosperity mainly

depends on the quality of its labor force, namely those who have been well

educated.

For individuals, education is the best way to improve oneself. Firstly,

its education thathelps people gain basic knowledge of the world, helping them

to distinguish what is right and wrong. Secondly, education improves ones

skills of life and work, which can make people live a good life or have

achievements in career. Finally, education brings people ability of learning and

that is the key role of education.

each year there is an increasing number of cars on the roads as millions of new cars are produced. one out of six americans works at making cars, driving trucks, building roads or filling up gas. americans couldnt live without cars!

most americans would find it hard to imagine life without a car. however, some have realized the serious problem of air pollution caused by cars. the polluted air becomes poisonous and dangerous to health.

one way to get rid of the polluted air is to make a car without pollution. but to build a clean car is easier said than done. progress in this field is slow.

another way is to replace car engines with something else. inventors are now working on steam cars as well as electric cars. many makers believe that it will take years to develop a practical model for us.

to prevent the world from being polluted by cars, we have to make some changes in our lives. americans, for example, have to cut down on the number of their total cars.they are encouraged to use bicycles, which are thought to help keep the air clean.

空气污染是空气中某些物质的含量超过正常含量时，形成危害动、植物，影响其生存的现象。大气中C0、NH3、SO2、H2S、Cl2、03和N02等物质的正常含量均在百万分之一以下，对动、植物没有明显的不良影响。但19世纪以来，由于工业和交通运输的发展，那些物质大量排入大气，使空气污染日趋严重，影响到动、植物生命活动乃至人体健康。

污染物的来源，有的来自自然界（如火山喷出的烟灰），有的来自人类活动，其中工业、交通运输产生的废气是主要的污染源。空气污染可分为气体污染物和气溶胶状污染物两大类。气体污染物包括SO2，、03，、氮的氧化物以及碳氢化合物等；气溶胶污染物包括固体粒子（粉尘、烟尘气）和液体粒子（烟雾、雾气）两类。直接向空气中排放的污染物质，叫一次污染物。空气与污染物之间相互作用，产生反应，或空气中光化学反应引起的污染物变质所产生的新污染物，叫二次染物。

空气污染物种类很多，其中对农业威胁较大的约有十多种，如SO2、 HF、C12和光化学烟雾等。 气象条件对空气污染物的影响，水平风速和对流层高度是影响大气稀释空气污染物能力的两个气象要素。当农田上空主导风向来自污染源时，农田容易受有害气体的危害；风力强弱则影响空气污染物的扩散速度、污染物在空气中的浓度与平均风速成反比；通常午后湍流强，空气处于不稳定状态时，有利于扩散。夜间晴朗无风，近地面逆温层可使污染物在地面上停滞积聚，加剧空气污染的程度。另外，在准静止的高气压系统中，由于下沉逆温阻止下层排放的污染物扩散到大气上层，可形成近几百米厚的污染层。各国多次发生的严重空气污染事件大都是在低逆温层、风速小和无雨的气象条件出现几天之后形成的。

空气中一些污染物例，如SO2和悬浮于空气中的农药颗粒等，经雨水淋溶落到地面，又可污染土壤和植株。污染物对植物的危害，一般是通过气孔进入植物组织，干扰酶的作用，阻碍代谢机能，有的有毒物质在体内还可进一步分解或参与合成过程，产生新的有害物质，侵害细胞组织，抑制光合作用，使生长受阻、产量降低、品质变劣。其危害分为急性、慢性和不可见危害等。高浓度污染物造成急性伤害，引起产量显著下降，低浓度污染物，在长时间作用下，造成慢性危害，一般症状不明显。不可见危害只造成生理上的障碍，一般没有症状。

植物受空气污染危害的程度，主要受下列因素影响：污染物浓度和植物接触它的时间；植物本身的构造和所处的发育期以及环境条件的影响。如充足的光照，适宜的温度、良好的供水和空气湿润，较高的C02浓度等，都能导致叶片气孔开放，易受污染危害。 植物对大气的净化功能。不少植物具有一种以酶作催化剂的潜在解毒力，能够分解一些有毒物质，或形成一些大分子络合物，暂时可以降低毒性。1公顷森林，每年可吸滞灰尘30多吨，1公顷柳杉林，每年可吸收700多公斤S02，柑桔树的叶子可吸收储存硫达1％，青杨和桑树具有较强的吸收铅尘的能力，加拿大杨、银杏、榆树、梧桐、桉树等都是较好的“天然吸尘器”。草坪的吸附粉尘能力比裸露地面大几十倍。因此环境科学的任务之一，是要充分发挥植物净化大气的作用。选择吸收污染能力强的植物，扩大造林绿化面积，根据污染源位置、污染物汇集区的地形地势、风向和污染气体的季节分配，统一考虑构成一种包围式或隔离式的林带，使含尘气流在移动中途被树林吸收。另方面要研究采取控制或减少排放污染物的措施，以保证大气质量符合规定的标准。

Aducation is not an end, but a means to an end. In other words, we do not

educate children only for educating them. Our purpose is to fit them for

life.

In some modern countries it has been fashionable to think that free

education for all can solve all the problems of society and build a perfect

nation. But we can already see that free education for all is not enough.We find

in such countries a far larger number of people with university degrees refusing

to do what they think is "low"work, and. in fact, working with ones hands is

thought to be dirty and shameful in such countries.

But we have only to think a moment to understand that the work of a

completely uneducated farmer is far more important than that of a professor~ we

can live without education,but we die if we have no food. If no one cleaned our

streets and took the rubbish away from our houses, we should get terrible

diseases in our towns.

In fact, when we say that all of us must be educated to fit us for life, it

means that we must be educated in such a way that, firstly, each of us can do

whatever work is suited to his brains and ability and, secondly, that we can

realize that all jobs are necessary to society, and that it is very bad to be

ashamed of ones work. Only such a type of education can be considered valuable

to society.

Everyone has their own habit. I have some living habits. I will take off my

shoes and put on the slippers when I arrive home. And I get used to drink some

soup before having dinner. What’s more, I have to keep my room light on until I

fall asleep. If I am forced to change anything about this, I will be very

uncomfortable. For example, if I don’t wear slipper at home, I will be very

uncomfortable. If I can’t drink soup before dinner, I can’t eat anything. And I

can’t fall asleep if the light is off. This is my living habit. Maybe I will

change it one day, but now I can’t receive any change about them.

My father used to be a heavy somker.He smoked more than 20 cigarets each

day;therefore,he was the polluter wherever he went.My mother and I tried to

persuade him to give it up.He gave it up many times but each time only for a few

days or only for a few hours.

Once he declared that he would stop smoking right away under the pressure

of my mother,and he threw his cigarets into the dustbin.The effect of his

declaration lasted only for two days.Then I found him smoking again when he

thought that he was alone and no one saw him.On the fifth day of his

declaration,he smoked openly.

Last winter he got pneumonia.When he was well again,the doctor ordered him

to give up smoking.To our delight,this time he really got rid of the habit.It

seems that the doctors order is more effective than mothers scolding,my

suggestion and his own declaration.

Health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out.

We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air.

If there are impurities in the air, they may be absorbed by our bodies and make us ill.

We need clean air, but unfortunately, air pollution is globally present, especially in cities.

Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things.

Every year these factories pour millions upon millions of tons of smog into air.

Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now.

Once out on the streets, they will take in fresh air and replace it with poisonous gases.

Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air.

Then, the sunlight will no longer be blackened out by smoke and soot.

Scientists

believe an animal source is "the most likely primary source" but that some

human-to-human transmission has occurred.

科学家认为动物是“最有可能的初始感染源”，不过，也有一些人传人的病例。

Signs

of infection include respiratory symptoms, fever, cough, shortness of breath and

breathing difficulties.

感染症状包括：呼吸道症状，发烧，咳嗽，呼吸短促，呼吸困难等。

2019-nCoV,

as its been labelled, is understood to be a new strain of coronavirus that has

not previously been identified in humans.

这种新型冠状病毒(2019-nCoV)此前未在人类身上发现过。

Coronaviruses

are a broad family of viruses, but only six (the new one would make it seven)

are known to infect people.

冠状病毒是一个庞大的病毒家族，目前已知会感染人类的有六种(新发现的这种是第七种)。

Nowadays,with the rapid development of our society,almost all the graduates

have to face a choice:to get a job first or to find the job you like first?As

far as I am concerned,the graduates should get a job first and then choose the

job they like.The reasons can be listed as follows:

First of all,for many students,even they themselves don’t know what kind of

job they want to choose.For these students,to get a job first can help them find

out their favorite job through trying different work.What’s more,the graduates

are all under great employment pressure.There are thousands of graduates need to

find their jobs every year.So if the graduates don’t get their jobs as soon as

they leave the school,they will miss the best chance to get a job.Last but not

least,one can accumulate experience and broaden horizons in his or her first

job.It’s certain that these experiences will contribute to future job.As the

famous saying goes “One should apply theory to practice.”,students should apply

what they have learned in class to their jobs,thus enhancing their working

skills.

Above all,nowadays under the greater employment pressure,the graduates

should get a job first and then to choose the job they like.Since students can

have a better understanding of what they like and gain experience in the first

job.
