高中英语作文教案教学设计（实用20篇）

我盼望已久的夏令营终于开始了，怀着紧张而又激动的心情走进中山大学珠海校区。眼前的一切一切都感到陌生。陌生的环境;陌生的营友;陌生的老师;好不容易拿到了一切证件和书本，接下来是找宿舍。随着拥挤的人群，终于来到了榕园。望着眼前这座高大雄伟的建筑物，想着我将在这里住半个月，我不亦乐乎。经过咨询，才知道我的宿舍在301。我们三步并作两步走了进去。哇，眼前的一切让我感到吃惊。宿舍又小又闷，而且没风扇又没空调，这半个月我要受苦了，真惨啊!但一想：来这里就是要学会独立自理的，又不是来享福，所以我要学会吃苦耐劳!

我们宿舍里每个晚上都有蟑螂、飞虫之类小虫子飞进来，我们都又怕又不知怎么办，只好呆呆地坐着。幸好宿舍里有两个高二的姐姐保护我们，否则我们不知该如何是好。晚上虽然有点热，但是感觉很新鲜，很快便入睡。

我们在这里天天都要上课。从宿舍走到教学楼需要一个钟头。而我们每天要走3个来回，所以想减肥的人来参加这个夏令营一定能减肥成功!我们上课是外教和一个助教上的。上课的形式很灵活，一会儿玩游戏，一会儿单词接龙，一会儿听老师讲故事。我们上课也很随便，外教不会要你坐得整整齐齐，我们喜欢干嘛就干嘛，可以到处乱走，可以下位同其他同学进行英语交流。因为外教喜欢自由，所以也让我们自由。

在这里，我认识了许许多多的朋友，同她们在生活上互帮互助，一起学习，一起聊天。每当我无聊时，她们便会讲笑话给我听;每当我作业不会做时，她们便会一题一题地讲解给我听，直到我会为止;每当我生活上遇到困难时，她们会尽自己最大的力量帮助我;每当我伤心时，她们会安慰我;同她们在一起，我觉得时间过得飞快，觉得十分开心!

在这里十分辛苦，要自己洗衣服、晾衣服，还有许许多多的事情需要自己做主。晚上，洗完澡后，便要自己将衣服洗干净。洗衣服非常辛苦，有时怎么搓都搓不干净，直到搓得双手红通通的，才搓干净一小部分。好不容易搓干净了，接下来是扭干衣服。衣服很重，我费了很大的劲才扭干，此时我已经累得气喘吁吁了。但是还要将衣服晾上去，晾衣服的那根竹竿太高了，我又太矮了。所以我只好请宿舍里的两个高二的姐姐帮忙。

我们每天上午就上课，下午就搞活动。下午的活动丰富多彩，有时候看外教跳舞;有时候爬山;有时候到图书馆看书;有时候上网;女外教们跳舞都很厉害，有时候还玩杂技，非常精彩!晚上，我们不是上课就是看电影——小鬼当家。小鬼当家这部电影很好看，是一部教育片。在场的同学常常看的哈哈大笑，现场也常常发出热烈的掌声。

时间过得飞快，转眼间12天已经过去了。舍不得同老师分离;舍不得同朋友分离;舍不得离开美丽的中山大学;但是，舍不得也要舍得。每当想到快乐的夏令营时，我会觉得很开心，那里是我和朋友们第一次认识的地方，在那里，藏着我们多少欢声笑语……

忘不了这次欢乐的英语夏令营，这个夏令营的确很快乐!

Dear Nate,

our city with the most beautiful campus. It has many trees, flowers and a lot of

excellent teachers in our school. Classes are interesting, the teachers are

Many people regard money as the most important thing in their life, but I dont agree with them. There are so many things that money cant buy. The first, money cant buy us knowledge, abilities and experience. The second, money cant buy us a happy mood and a good health.

However, money plays a significant role in our daily life. We cant live without it, because we have to use money to buy our daily necessities, like food, drinks, clothes, books, and so on. And we also need money to pay for our houses and education.

All in all, we should have a correct concept of money. We cant live for money, but take it as a tool leading a better life.

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

Before Teachers Day, we were thinking what gift we would give our liuxue86.com English teacher on that day. Wang Ming said, "Our English teacher is tired and shirsty after class. Lets give her a bottle of water. " "Thats a good idea,"we agreed."

On Teachers Day, as soon as the teacher came into the classroom, we all stood up and shouted "Happy Teachers Day!" Our monitor went to the from and gave her a card and a bottle of water with our best wishes. Our teacher dran.

The people I respect the most is my father. He is a doctor. He always busy

with work. Since I can remember, he never spent a whole weekend to stay with me.

He goes to the hospital very early before I get up, and comes back home after I

sleep. But I doesn’t matter at all, he is hero to me. He devotes almost all the

time to his patients, many lives are saved. He always said, a man should have

dignity, integrity, honor, and most of all, be helpful to others. This affected

me deeply, so I work hard so that someday I could be the man like my father.

April 23 is "World Book Day" announced by the UNESCO。

This is not a long history of the festival, from 1995 began. However, it has been widely welcomed and responded in the world: held in Copenhagen, Denmark reading marathon, Canadas Toronto Festival held in Canada…

When these popular cultures such as Pop music and Hollywood movies get quite prevailing today, people have not forgotten literature, the writers and reading.

Whether Reading is a funny thing, only love reading people know.

I study for many years, however, I know the sense of reading so little . Where fun of reading comes? There are four opinions put forward in this paper.

First, Reading is the treatment of depression governance magic.Immersed in books, what partiality, what desire fame and fortune, what lack a clear round, what fuel, what life 3,000 silk trouble, they all forget about.

Second, People in Libraries are often forget the time and forget to go home, that the study is not the intrinsic happiness? Some celebrities even held overnight in the library.

Third, We often see someone reading forget thirst. India, reading knowledge is the spirit of Canadian admirable. However, the morning watching a professor at the empty plates and ask ourselves: I eat the lunch? Oh. After eating, they continue schooling. Some people forget to study cooking and was good meal blame reprimanded.

Last, Reading the fastest time flies. Joy of reading, an unconsciously Influence past, the sun has not allowed Health attraction downhill whims.

People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path along a river or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus. net

When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

究其原因，我结合自己的写作体会总结了三点。其一，对英语作文不熟悉，虽然篇幅要求不大，字数在150字左右，可还是难倒一大片。其二，对某一问题平时缺乏思考和总结，不能提出明确的看法和见解，缺乏层次感。其三，不熟悉英语语法和一些常见的单词，即使知道意思也无法清晰表达出真实意思。

为此，我结合本学期的第一篇作文，给学生做了详细讲解。写一篇作文需要四大步：First, consider it carefully. (第一，认真构思。)Next, draw up an outline.(第二，写出文章结构。)Then, write the composition.(第三，写出作文。)Finally, Check over the composition.(最后，检查文章。)四步骤中，难的是第二，第三步。现结合文章，具体谈一下怎么做。

Conclusion: Thanks to the government’s efforts, Li Ming’s hometown is becoming more and more better. (结论：多亏政府的努力，李明的家乡变得越来越好了。)

下面我把参考译文写出来，供大家参考。

[高中英语作文：我的寒假

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

Everyone has their own dreams， I am the same. But my dream is not a lawyer， not a doctor， not actors， not even an industry.

Perhaps my dream big people will find it ridiculous， but this has been my pursuit! My dream is to want to have a folk life! I want it to become a beautiful painting， it is not only sharp colors， but also the colors are bleak， I do not rule out the painting is part of the black， but I will treasure these bleak colors! Not yet， how about， a colorful painting， if not bleak， add color， how can it more prominent American? Life is like painting， painting the bright red color represents life beautiful happy moments. Painting a bleak color represents life difficult， unpleasant time. You may find a flat with a beautiful road is not very good yet， but I do not think it will. If a person lives flat then what is the point?

Life is only a short few decades， I want it to go Finally， Each memory is a solid.

三、巩固练习：

板书设计：大数的改写和省略

反思：

教学目标：

知识与能力目标：激发学生对生活的热爱，引导学生观察身边熟悉的事情，丰富习作素材。调动学生思考和练笔的积极性。

过程与方法目标：从拟题到构思，鼓励学生不拘形式，自由表达，合作探究，有序地说和写。

重点难点：如何有序表达、如何抓住重点及细节描写，把事情的经过写具体写完整。

课 时：第一课时

教学过程：

一、激趣导入，引发欲望

1.同学们，今天这节课，我们要一起玩个游戏[板书：打手背]齐读。

2.从同学们的声音中，老师了解了你们的心情，谁来说说听到老师说要玩游戏时，感觉怎么样？

二、创设情境提供素材

1、指导学生学会自拟题目

（1）启发谈话：

同学们先两人一组自由的玩一玩。你们觉得开心吗？这节课就把你的快乐写下来吧!在写之前先要确定一个恰当的题目。（板书：拟题）

（2）教师小结。记事类文章拟题的一般规律，既可以按时间或地点拟题，也可按中心事件拟题。还要注意拟题新奇。同学们说一说怎样拟题？

（3）教师小结。幻灯片出示：《一次有意义的游戏》 《这次游戏真开心》 《难忘的拔河背比赛》《友谊第一，比赛第二》 《那一次，我哭了》《那一次，我赢了》 《那一次，我输了》《忘不了那个时间》 《今天是个好日子》 《热闹的课堂》……

（4）让学生根据习作素材自拟题目。

2、学生报题

有创意的题目奖给耕耘奖。

三、巧妙引导交给方法

1、教给学生采用多种形式开头的方法

（1）文章拟好了题目，我们先写开头。人们常说万事开头难，一篇文章如果有好的开头,能产生“开门红”的效果。因为读者看文章总是从开头读起的，因此我们一定要写好文章的开头。（板书：开头）

（2）教师归纳小结。常见的开头形式主要有以下几种：

1、上星期五，我们五乙班在学校南面的水泥路上举行了一次别开生面的野餐活动。（在开头就开门见山，交代时间、地点、人物和事情）

2、 操场中间的水泥路上，躺着一根又粗又长的绳子。绳子两头各站着十几个精神抖擞的男同学，个个摩拳擦掌。路两边，坐满了全校同学，大家有的挥舞着红领巾，有的甚至跳上了凳子，不停地呼喊着。原来，这里正在举行全校的拔河比赛呢！（可以运用“场面描写法”，以烘托热烈的气氛，吸引读者的阅读兴趣）

３、那天，班主任徐老师让我们进行一次吹鸡毛比赛。同学们听了，不禁瞪大了眼睛，迷惑地看着老师，小声嘀咕着，谁都知道鸡毛轻飘飘的，怎么吹呢？（采用设问开头）

2、帮助学生掌握“有序”的表达方法

（1）启发谈话：刚才老师说玩游戏，你们的心情怎样，看到周围同学的表现又是怎样的

（2）明确规则。

a.从你们的语言中，老师感受到你们是迫不及待地想玩这游戏了。那老师先来说下游戏的规则，我只说一遍，你们要认真听，比赛规则是这样的：比赛双方面对面站立，左手背回背后，右手伸出来，两手相对，一个人的手心向下，一个人的手心向上。当老师发出口令“一、二、三，开始打，打住者获胜，没打住者翻过来让对方打。（注意只打住就好，注意力度）

听清楚了吗？谁来说一说呢？（指名一生交流）

说的真棒，记忆力可真好，你们能像他一样吗？

b.写比赛规则 [板书：比赛规则]（书写3分钟，要求：不说话，不抬头，不停笔。）

c.再指名一生交流比赛规则。

3、 备战气氛。

（1）请前后桌同学面对面站立，我们马上就要开始游戏了，老师要提醒你们：一定要听好老师的口令。

（2）喊口令“1！2！暂停！”刚才老师是考考你们的反应能力呢！瞧瞧怎么样啊？老师现在来采访你们下：a、刚才教室里静悄悄的，你的心跳得快吗？像什么呢？b、你的眼睛在干什么？心里想什么？c、你看到你对手的表现了吗，怎么样的？

（3）这就是我们在备战时的一个情景，[板书：备战体验]请把你的体验写一写。（时间3分钟，要求：不说话，不抬头，不停笔。）

(4).指名两生交流。

4、 记录自我。

（1）比赛正式开始，“1！2！3！开始！”

（2）刚才老师口令一发完，教室里爆发出怎样的声音呢？胜利的同学请举手，你来说说为什么会取胜啊！

（3）写一写：记录真实的比赛过程。[比赛过程：经过 结果] （时间4分钟，要求：不说话，不抬头，不停笔。）

（4）指名两生交流。

5、 观察他人。

（1）刚才同学们留心观察了自己的体验，现在老师要求同学们注意观察他人的表现。注意他的动作、表情、语言等。

（2）分两组进行比赛。

（3）写一写刚才观察到的情况。（时间3分钟，要求：不说话，不抬头，不停笔。）

6、小结

咱们班的同学观察力较好，希望你们今后在生活中要做有心人，老师相信你们能行。

Going to high school is my first time to leave home. I have to live in school from Monday to Friday. I like to stay away from my parents for some time, because I can make my own choice and be free to go anywhere. My friends and I like to spend the weekend in the countryside that near the city we live. It is the short travel that I can not only appreciate the beautiful scenery, but also learn to be independent. The things that nature teaches me are a lot. I can see from the color of the cloud to predict the weather and the sound of of animals have different meanings. All of these are hard to know from the books. I have my own thinking from these trips, and the way to take care of myself helps me to grow up.
