[初中英语日记美好的一天

One day I was on a bus. I found an elderly woman standing in front of me. She had a big bag in her hand. "Its a virtue for a young person to help the old,"I said to myself. When I was standing up to give my seat to the old lady, a young foreigner got up quickly saying, "Please sit down."The old lady thanked him and sat down. She looked very happy.

I was a little embarrassed because I was sitting in the middle of the bus.Suddenly a pregnant woman got onto the bus. I quickly stood up to give up my seat to her. Theforeigner smiled at me. He said that he was an Australian, and was a student studying Chinese culture in China.

First, I’ll say something about World Expo History. As we know, the very first World Expo, the Great Exhibition of 1851, took place in the Crystal Palace in London. UK. Ever since then, the goals of World Expos have been both high-minded as well as commercial. Visitors are able to explore the world outside of their everyday experience—outside cultures, new scientific advancements, and new inventions. World Expos have excited and inspired more and more people in the world

On December3, 2002, the Bureau of International Expositions (or call it BIE) announced that Shanghai will host Expo2010. the BIE had received bids from five cities to host Expo2010. Among the 5 nice cities, the BIE chose Shanghai at last! It’s really an exciting news for not only Shanghainese, but also all of Chinese people. Here are some details about it.

Loot at this profile carefully. The title is “The 2010 World Exposition ,Shanghai, China ”。 this is the logo.

And the theme is “better city., better life”。OK, let’s guess who is the image representative? Yeah, you’re right, Yao Ming!

Shanghai Expo is the first comprehensive World Expo held in a developing country. And it is also the first one that takes “the city” as its theme, hoping that it can push forward the city development and help bring about a better urban living environment, just like the theme: better city, better life.

I think, as a student in Shanghai, we should learn to be a gentle person and keep good manners from now on. And try to practice English more in order to communicate with foreigners fluently in the near future. Because, we’re a part of Shanghai!

机遇是成功的因素之一。但是机遇并不经常光顾小学生作文 你也可以投稿，而且并不是所有机遇都必然导向成功。除此之外，机遇通常就在刻苦的工作中，只是许多人觉察不到而已。因此如果你想成就事业，就必须努力工作以做好迎接机遇的准备。否则，即便机遇来了你也会失去它。我认为，我们社会中的每个人都有许多机遇，但只有那些做好充足准备的有才能的人才会利用机遇取得成功。

Opportunity and Success

Opportunity is one of the elements of success. But opportunities don’t come often. And not all the opportunities can certainly lead to success. Moreover, opportunities are usually disguised as hard work; therefore most people don’t recognize them. So if you want to achieve something, you must make efforts and get prepared. Otherwise, you will take no advantage of opportunities when they come to you. In my opinion, there are plenty of opportunities for everyone in our society, but only those who have made enough preparations and are highly talented can make use of them to achieve their purpose.

Last summer I went to the beach. My vacation was pretty good. I went there by bus and my bus trip was relaxing. The beach was very beautiful. It was sunny, cool and humid.the people were friendly and the food was delicious.

I enjoyed my vacation very much and I hope to go there again.

I did not act like one; instead, I even encouraged others to cut classes, too. of course. I was caught out and severely punished. Often in preparing for a test we pupils would work together to devise ways of cheating in the test room. Though I was poor at cheating in any test.

暑假我和爸爸妈妈一起去新疆旅游，丝绸之路的每一站都充满美景和神奇。

我们到达的第一站是十三朝古都西安，那里的秦兵马俑世界闻名，是统一中国的秦始皇造出来陪葬他的，宏伟壮观，栩栩如生。

第二站是敦煌，我们是坐火车去的。在丝绸火车上我认识了几位新朋友，她们是同一个旅行团里的三位即将读高中的大姐姐。火车第二天晚上８点才到目的地，虽然坐了一天半的时间，但因为结识了这么多新朋友，我们在火车上玩得开心，所以一点儿也不觉得累。

第二天一大早，我们去了鸣沙山、月牙泉，欣赏到无边无际的沙漠风光，骑着骆驼探寻沙漠中的奇观——不会枯竭的月牙泉。在敦煌，我们还看了莫高窟壁画，里面有飞天仙女、反弹琵琶舞，真不愧是古代能工巧匠的作品！可是听讲解员阿姨说，这么珍贵的古迹，现在却面临着被沙漠吞没的威胁。

第四天，我们再一次乘火车到达新疆著名的葡萄园——吐鲁番。我们享受着甜美的葡萄，欣赏了优美的新疆歌舞，体验了火焰山的炎热，观赏了令人惊叹的水利工程——坎儿井。

在依依不舍中告别吐鲁番的葡萄园，我们来到了此次丝绸之路旅行的终点站——乌鲁木齐，游天山天池，扮新疆姑娘，吃羊肉串，看惊险的“达瓦孜”高空走钢丝节目，尽情感受新疆的热情……

这次旅行，让我看到了祖国山河的美丽，体验了不同民族的风情，欣赏了古代人民的智慧成果，学到了很多历史和地理知识，还结识了很多新朋友。

The summer vacation had come round again。 I was happy that I could forget about school at least for a while。 Lest I fool around all through this summer vacation， I made a plan as to how to spend it。 First， I thought I should go over all those things my teachers taught in the previous term so that I could have a better understanding of them。 Then I thought I should take up some forms of exercise， such as walking， running rowing， to keep me physically strong。 It stood to reason that with such a good plan I should make the best of my vacation time。 I did， because I lived up to what I had planned。

My school life is very common. I get up at six o’clock every morningfrom Monday to Friday. And the I would go running with my classmates, as our head 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.

Nowadays the newspaper possesses considerable value Everybody should read it. It supplies us with a variety of news every day. It tells us the political situation of the world. If we form the habit of reading the newspaper, we shall (will) get enough knowledge to cope with our circumstances.

现今报纸拥有极大的价值，人人都应该看它。它每天提供我们各种类类的消息。它告诉我们世界政治局势。如果我们养成看报的习惯，我们就能得到足够的知识来因应我们的环境。学生虽然每天须做功课，但他们至少应该匀出一两个小时来看报。哪些，他们不但能增加知识而且也能赶上时代。总而言之，看报对学生很有益处。

Dear Michael，

You want to know the changes about my hometown。 You know， great changes

have taken place since 60 years ago。

In the past， the living conditions were very poor。 There were not many

buses or cars， and the roads were narrow。 Usually， a big family was crowed into

a small， dark house。 Most families couldn’t get enough food。 The communications

were simple and slow。 People kept in touch with their friends and relatives far

away mainly by letter or telegram。

Thanks to the government， our hometown has developed rapidly in recent

years。 The living conditions are much better and more comfortable。 The roads are

wide。 Some people have their own cars。 Most of the people have lived in big new

houses。 Quite a few adults have mobile phones。 Because of many good policies， I

think our lives will become better and better。

Sincerely

Kang Min

初中英语作文:初二英语作文 Our School Life

I don＇t think our school life is colorful. Because we＇ve got so many classes every day. I wonder whether we can change our school life someday. You see, from Monday to Friday, I have to stay at school. the only relaxation is to listen to the radio or play ball games. At weekends, we need to go to school to have classes, too. I know it＇s very important for us to study well now. As the saying goes, "All work and no play makes Jack a dull boy. "I want to step into the nature. I hope we will have more activities such as visiting museums, taking part in different kinds of contests, attending some lectures and so on. Is it only a dream?

As is 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 nmch 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.

How is it, you do not believe it? Look, she has left her footprints everywhere.

The air is so fresh, the weather is so blurred. The sun is warmer. Her million gold happy kiss all things, so gentle, so comfortable.

Its time to fall!

Section just after the autumnal equinox, they feel a bit cool. Gradually yellow leaves can not withstand the wind and rain to destroy the destruction of a piece of leaf leaves falling in the high and low roof, falling on the road in large and small, falling in criss-crossing the river.

Autumn rain is light blue, crystal clear. 10 million silver, rippling in the air, fans of the veil, draped over the dark faint fields. The rain fell in the water, like a thrown into the crystal jade plate, splashed grain pearls; rain fell on the tree, like to branches with soft hair; rain fell to the ground rolled up a burst of smoke, the land seems Blooming out of a laughing dimple.

The autumn of autumn, grooming the mountains, nourishing the earth. The puddle of water on the ground is full of water. They slowly flow to the big ditch, brought together this years affection and hope of the coming year. This autumn is as if it is sweet wine, dedicated to the breeding of all things of the land, dedicated to the harvest full of joy ... ...

Autumn is not annoying. Behind the misty rain curtain is a sweet smile. It is to celebrate the birthday of the motherland smile; that is the fruit of the mountains and plains of the red face. "Autumn autumn rain sad people" era, in the golden autumn of the motherland, has long gone.

I look up at the blue sky, think the sky is more sunny, the sun is more brilliant, a blossoming light like white clouds, like to the blue sky embroidered with white flowers. This view makes the breathtaking.

Autumn rain is not only wonderful, but also full of new hope.

Ah! Autumn rain - intoxicating autumn rain.

Last year, I traveled to Beijing by train. I was very fast. But, I like travel by train, because I like the feeling in the train. Besides, I can enjoy the scenery on the way. However, after the journey last week, I dont want to travel by train anymore, because it is too tired to have fun. It took me sixteen hours on the train. I was very tired and I had to spend a day to have a good rest. And it was boring on the train. Therefore, I think it should not travel by train if its far.

When I was very small, I stayed in the hometown with my grandparents. I had the great time there, I liked the environment so much. There was a long river in front of my house, the water was very clean, I could see the small fish swim. My grandma usually washed her clothes along the river side. But now when I went back to my hometown, the river was very dirty, the water was light yellow and there were so many rubbish floating in the river. It made me feel that the river had lost its life. I missed the old time when I was playing in the river. It is human being that ruin the environment, if we don’t take action to protect it, we will destroy ourselves.

Haze? Nanjing and other places of dust is overmuch, combined with the dust and fog, becomes the haze, inhaled into people get lung disease, asthma and other respiratory diseases.

Recently, pm2.5 is close to the extraordinary, in nanjing today at 3 o clock in the morning, pm2.5 has reached 466 micrograms of a cubic meters, entered the serious pollution, pm2.5 is one of the "culprit" haze weather. Not just the pm2.5 exceeds bid badly, pm10 has recently started to crazy, 3 a.m. yesterday, pm10 has reached 579 micrograms of a cubic meters, the nanjing the worst pollution index was about to break! In addition, the sky appeared a "mock sun"! Is too much because floats in the sky. If nanjing on October 1, the sky is blue, so today in nanjing will be gray and a piece of the sky.

Fog not only have an effect on the human body, many planes, ships, cars and so on all cant normal travel. Nanjing lukou airport has 53 flights affected by haze on time boot. Many highways have been closed, the highest visibility on the streets of only 10 meters the following, the car travel is very inconvenient. Hundreds of ships to stay in the Yangtze river in zhenjiang. The influence of the fogs really big ah!

We air pollution index of the middle and lower reaches of the Yangtze river has been more than the north, like tianjin, Beijing, hebei and other provinces, cities have been we left behind. The factory in the north is more, to produce a lot of dust, according to the reason for the northern cities should air pollution is the most "powerful", can be in November to December Chinas worst air index, almost all is our "occupy" in jiangsu province.

Now that the fog is so terrible, we should also consider what to do! 1, when faced with heavy fog, the first thing to hide the fog haze. Haze days dont go out as far as possible, dont get up early to exercise more. 2, mask is fog out of necessity. Will always wearing surgical masks, but not always wearing a mask, only on the road, a lot of bacteria such as hospital, pm2.5 wear a lot of place, at other times, try to put in my pocket.

This is the fog haze, a great influence on our body, we must learn to prevent it! That is why our school classes.

今天我们同学都留在家里不去上课。你们知道为什么吗?对了，就是因为雾霾。

雾霾是什么呢?南京等地的灰尘过多，而雾跟这些灰尘相结合，就变成了霾，人大量吸入会得肺病、哮喘等呼吸道疾病。

最近，南京的pm2.5接近爆表，到了今天凌晨3点，pm2.5已经达到了466微克一立方米，进入了严重污染，pm2.5是雾霾天气的“罪魁祸首”之一。不仅仅是pm2.5超标严重，pm10最近也开始疯狂起来，昨天凌晨3点，pm10已经达到了579微克一立方米，这项指标就快要破南京最差污染了!而且，天上还出现了一个“幻日”!就是因为天空中的漂浮物过多而形成的。如果说10月1日的南京的天空是湛蓝的，那么今天南京的天空将是灰蒙蒙地一片。

不仅雾霾对人体有影响，许多飞机、船只、汽车等都不能正常出行。南京禄口机场已有53个航班受雾霾影响不能准点开机。许多条高速公路都已经关闭，街头的最高能见度才仅仅10米即以下，这让汽车出行非常不方便。数百只船只停留在长江镇江段。雾霾的影响可真大呀!

我们长江中下游的空气污染指数已经超过了北方，像天津、北京、河北等省、市都已经被我们落在后面。北方的工厂较多，会排出很多的灰尘，按道理来讲北方城市应该空气污染是最“强”的，可11月到12月中国的空气最差指数，几乎全部是我们江苏“占领”的。

既然雾霾这么可怕，我们也应该想想该怎么办吧!1、当遇到浓雾天气，首先要躲雾霾。雾霾天尽量不要出门，更不要早起锻炼。2、口罩是雾天外出的必需品。要常带口罩，但不能常戴口罩，只有在马路上、医院里等病菌很多，pm2.5很多的地方戴，其他时候，尽量放在口袋里。

这就是雾霾，对我们人体影响很大，我们要学会预防它哦!这也就是我们学校为什么停课的原因了。
