Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, mans changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise, man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings

历史上的人改变了他的物理环境,以改善自己的生活方式。借助技术工具改变了地球的许多自然特征。他将林地和草原改造成为农田,使江河变成湖泊和水库,用于灌溉或用于水力发电。男人也修改了地球表面由高山沼泽和切断山区修建公路和铁路。

然而,人的物理环境的变化并不总是有有益的结果。今天,空气和水的污染是越来越危害地球的健康。每天成千上万吨的机动车辆的排气管排出的气体排放出来。工厂释放的烟雾污染了空气工业化地区和周边地区的农村。水的污染也同样有害。海洋的整个生态平衡正在改变,工业废物已经使许多河流毫无生气。

现在,环境保护比以往任何时候都更为紧迫。正如我们所知,环境的巨大破坏已带来负面影响,甚至对人类造成巨大威胁的存在。对这些问题漠不关心将意味着自杀。因此,应采取有效措施并通过法律来保护环境。不然的话,人类势必遭受缺乏所造成的严重后果关心生存环境

When winter comes, the topic of haze will never be ignored. When it comes,

many pictures will be showed. People make fun of these pictures and they

actually laugh at themselves, living with these poison air. Even in the daytime,

people can’t see their faces beyond 10 meters. Many schools choose to stop the

class and let the students stay at home. It is obvious that haze is a great

threat to people’s health. This new type of destruction is the result of

Once, I talked to the foreign people, he was staring at me all the time,

which made me feel not comfortable, so I chose to avoid his eyes and kept a

little distance from him. When I talked about this problem to my foreign

teacher, she told me that it was natural for them to look at you during

communication, which meant respect. While in China, people do the opposite

thing. They try to avoid eye-contact, because it is not eased to look at each

other. The different culture sometimes creates distance. The foreigners always

feel strange when they look at Chinese people’s eyes and every time when they

want to come closer to hear more clearly, Chinese people will walk away. So the

more we learn about the culture, the more we know about the world.

篇3:初中英语说明文写作要点

全文共 1976 字

+ 加入清单

说明文是阐述事物的特征、本质、性能、结构、用途或科学原理的一种文体。其说明的对象可以是具体的,如:自然环境,仪表设备等;也可以是抽象的,如概念定律等。以下是小编整理的初中英语说明文写作要点,欢迎阅读!

说明文的写作相对于论说文来说,有一定的套路可循,因此不是十分复杂。说明科技方面的内容常用定义法、比较对比法、分类法、因果法等;说明自然环境方面的内容常用时间次序法、分类法等。当然,随着对象的不同,具体应该采用的方法也会有所不同。

说明文的写作应该注意的事项有下面几点:

1.语言简明扼要,通俗易懂,避免夸张华丽的辞藻,要把真实的一面展现在读者面前。

2.说明时一定要把握一个中心主题。说明文中细枝末节较多,但不能喧宾夺主。

3.说明的次序非常重要。合理的次序会使文章条理清楚,脉络明晰。因此,练习时可以尝试不同的次序进行写作,找出最合理的一种。

4.由于说明文写实性较强,有时难免会让人感到没有生气。因此,可以适当使用一些比喻、拟人等修辞手段,来增加文章的色彩。

下面是一篇说明一所医院布局的文章。文章虽短,但需要说明的内容却达11处之多。平均一句话就要描写一处,如果组织得不好,便会给人凌乱的感觉。

为了避免这一点,文章把整个布局图分三部分来写:

贯彻医院的是main road,第一部分以大门为参照物,介绍了靠大门且通过main road东西相对的急诊楼和门诊楼。

第二部分以湖为参照物,中心线还是main road,介绍其他分诊楼、实验室、放射室等。

第三部分写main road尽头的建筑物。

这样,繁多的细节显得井井有条。因此,选择好主线及参照物是决定文章成功的关键。

The protection of the border is not a new problem for us, and our

government has long proposed clear targets for governance. As every ordinary

person in real life, although it is impossible to work directly in environmental

protection, we can start from small things and start from me. Can you raise your

hand when you see the tap in the bathroom? When the battery runs out, can you

classify it instead of throwing it away? How about when shopping doesnt use

ultra-thin plastic bags? ...... Small things are small, but they reflect how

much environmental awareness we have.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save

17 tree. 20 waste recycling boxes can create a beautiful pen container.

Recycling one glass bottle to save the energy, can make the bulb light for four

hours. Recycling one aluminum can is to save the half oil cans. So we should

The news that Mr Cai had passed away was known, and I fell into great

sorrow. The sound of the rain knocking on the window was so mournful that it

deepened my distress.

My memory brought me back to the class when I saw him for the last

time.

That evening it was raining, too. We started our lesson as usual at a

quarter past six. I sat in the first row, and I saw Mr Cai press his stomach

with a hand from time to time, but I didn’t know the reason then. The two hours

passed quickly. When the lesson came to an end,Mr Cai told us that he had

possibly developed a stomach cancer, and would go to Beijing to see a doctor. If

there was nothing serious, he would continue to teach us after he came back. He

was very calm and his voice was steady. He still gave us some homework. He said

that he would mark the papers as soon as he came back.

Then I started to wait for his return. I had not thought that I would not

see him any more. The cancer had taken his life, even though he was still

young.

Mr Cai’s words are still ringing in my ears,“I hope you will be one of the

best students.” I think I should work hard at English and live up to his

expectation .

I have lost a good teacher. Tears will dry up in time, but the memory will

stay for ever.

The way of learning English

Nowadays, English has become the international standard language. As China is stepping to the internationalization, learning English is more and more important. But many people find it hard to learn English well. According to my own learning experience, I think determination, read English materials and patience are the most significant.

如今,英语已经成为国际标准语言。由于中国正在迈向国际化,学习英语变得越来越重要。但是许多人发现很难学好英语。根据我自己的学习经验,我觉得决心,阅读英语材料和耐心是最重要的。

First of all, doing everything needs determination. Determination is a prerequisite to do something. When facing difficulty, the people who have determination will insist, on contrary, thepeople who don’t have determinatin are easily give up. Thus, if people wants to do something well, the first thing they need to do is to make up their mind. Secondly,reading English materials is a great help for learning English. It can help people raise sense for English language,have interest and confidence in Engilsh. That will help people a lot in the process of learning. Last, patience is necessary in English learning. Most people will feel difficult to learn English at the beginning. The people without patience will often upset towards learning English. As a result, it will increase the difficulties of learning English and vice versa.

首先,做所有的事情都需要决心。决心是做一件事的一个先决条件。面对困难时,有决心的人会坚持下去,相反,那些没有决心的人则很容易放弃。因此,如果有人想完成一件事情,他们要做的第一件事是下定决心。其次,阅读英语材料对学习英语有很大的帮助。它可以帮助人们提高英语语感,对英语有兴趣和信心。这将在学习的过程中对人们的帮助很大。最后,耐心在英语学习中是必须的。刚开始学习英语的时候大多数人都会觉得很难。没有耐心的人对学习英语会经常感到心烦。结果就是增加了学习英语的困难,反之亦然。

In general, determination, reading English materials and patience are the effective ways to learn English. If people recognize those, they will learn it well sooner or later.

总之,决心,阅读英语材料和耐心是学习英语的有效途径。如果人们意识到这些,他们迟早都会学好它的。

亲爱的父亲,你脸上的皱纹记载着沧桑,年龄已老一脸的慈祥,儿女心中你的身影,永远伟岸和坚强。下面是小编分享的父亲初中英语作文,欢迎大家阅读!

今天是父亲节,想到爸爸平时那么辛苦,我决定送一个礼物给爸爸,不过我不知道送什么好,突然,我想到妈妈和爸爸那么好,一定有什么好的建议。

于是,我去找母亲商量怎么让父亲高兴。可是,我和母亲两个人商量了好一会儿都没有想出办法来。后来,还是我灵机一动才想出了一个好办法。我立刻对母亲说:“父亲的胡子很多,而且经常会长出来。而且他比较忙,所以,我想买一把剃须刀给爸爸。让他一有空就可以剃去胡须。妈妈,你说好吗?”“好呀,孩子你想到真好!”我听了别提有多高兴了。

于是,我和妈妈一起来到了一家专卖店。那家商店东西真多呀!可是,我想到自己是来买剃须刀的。于是,我直奔陈列剃须刀的柜台。我挑选了一会儿,看到一把银白色的剃须刀既好看又实用,而且价钱也不贵。于是,我掏出自己带来的平时省吃俭用积累起来的钱,给了老板,拿了那把银白色的剃须刀就和妈妈一起走了。走出商店,妈妈对我说:“送你父亲一样东西不太好吧,再去买一样,好吗?”“好呀,只是我带的钱不多了。”“那没有关系,我这儿有钱。”于是,我就和妈妈一起去了蓝房子——一家专卖贺卡和礼物的商店。进了商店,我立刻开始挑选。我选好了一张可爱的小贺卡。妈妈看了以后说我的眼光真不错。

回到家里,我马上在贺卡上写上我对父亲的祝福语言。然后,我把它和剃须刀放在一起,耐心地等待着。

父亲下班回家来了,我立刻迎上去把礼物和贺卡递给父亲。父亲看到这一份特别珍贵的礼物,迫不及待地看了起来。等到看清礼物以后,他的嘴巴都张开成了“O”型。

然后爸爸非常开心的把我抱起来了,妈妈在旁边看到我们这样,也非常的开心。晚上,妈妈还做了很丰盛的晚餐,我们全家在父亲节过得非常的开心。这真是一个难忘的父亲节。

Today is fathers day, thinking of what my father had always so hard, I decided to send a gift for dad, but I dont know what is good, all of a sudden, I think of mom and dad so good, there must be some good advice.

So I went to talk to my mother about how to make my father happy. But my mother and I discussed it for a while, and we didnt figure it out. Then I came up with a good idea. I immediately said to mother: "fathers beard, and often grow. And he is busy, so I want to buy a razor to dad. Let him can shave beard. Whenever you have a mom, what do you say?" "Well, what a good thing you think of a child! I didnt hear how happy I was.

So my mother and I went to a store. What a lot of things in that store! But I thought I was here to buy a razor. So I went straight to the counter where the razor was displayed. I picked it for a while and saw a silver-white razor that was both nice and practical and inexpensive. So I took out the money I had accumulated, and gave it to my boss, and took the silver-white razor and went away with my mother. Walking out of the shop, my mother said to me, "its not so good to send your father. "Well, I dont have enough money." "It doesnt matter. I have money here." So I went to blue house with my mother -- a shop that sells CARDS and presents. Entering the shop, I immediately started to pick. Ive chosen a lovely little card. My mother said I had a good eye.

When I got home, I immediately wrote my greeting to my father on the card. Then I put it alongside the razor and waited patiently.

When my father came home from work, I immediately welcomed the gifts and CARDS to my father. The father saw the special gift and looked at it eagerly. By the time he saw the gift, his mouth was open to "O".

Then my father was very happy to pick me up, and my mother was very happy to see us. In the evening, my mother made a big dinner, and my family enjoyed their fathers day very much. It was an unforgettable fathers day.

篇17:2024年初中英语作文写作技巧

全文共 1442 字

+ 加入清单

小编导语:英语作文是英语考试中的一个得分点,那么在写作过程中有什么技巧呢,下面是小编收集整理的相关资料,希望对您有所帮助。

1、首尾呼应,画龙点睛在文章的结尾,把含义较深的话放在末尾,以点明主题,深化主题,起到画龙点睛的效果。如“I Cannot Forget Her” (我忘不了她)的结尾:

After her death, I felt as if something were missing in my life. I was sad over her passing away, but I knew she would not have had any regrets at having given her life for the benefit of the people.

2、重复主题,句结尾回到文章开头阐明的中心思想或主题句上,达到强调的效果。如“I Love My Home Town”(我爱家乡)的结尾:

I love my home town, and I love its people. They too have changed. They are going all out to do more for the good of our motherland.

3、自然结尾随着文章的结束,文章自然而然地结尾。如“Fishing”(钓鱼)的结尾:

I caught as many as twenty fish in two hours, but my brother caught many more. Tired from fishing, we lay down on the river bank, bathing in the sun. We returned home very late.

4、含蓄性的结尾

用比喻或含蓄的手法不直接点明作者的看法,而是让读者自己去领会和思考。如“A Day of Harvesting”(收割的日子)的结尾:

Evening came before we realized it. We put down our sickles and looked at each other. Our clothes were wet with sweat, but on every face there was a smile.

5、用反问结尾

虽然形式是问句,但意义却是肯定的,并具有特别的强调作用,引起读者深思。如“Should We Learn to Do Housework?”(我们要不要学做家务?) 的结尾。

Everyone should learn to do housework. Dont you agree, boys and girls?

6、指明方向,激励读者结尾表示对将来的展望,或期待读者投入行动。如“Lets Go in for Sports”(让我们参加体育运动)的结尾:As we have said above, sports can be of great value. They not only make people live happily but also help people to learn virtues and do their work bettter. A sound mind is in a sound body. Lets go in for sports.
