介绍自己的特长英语作文初一经典20篇

I, a girl with short hair, under the care of parents, in full 11 years old

this year.

With 11 years of faults: a careless, harm to me the most bitter, he let me

with a full pass by, let me wrong a 39 + 26 addition topic; Let me see the plus

sign as a minus sign, the division sign as a multiplication sign; Let me

actually took the math book on Chinese classes; He even want me to write in

Chinese this math homework! Im fed up with him over the years, determined to put

him out of the "home".

In recent years, careless a whim, let me put the eye became nearly three

baidu nearsightedness, pestering glasses, became I was like peas and carrots

"good friends", this "thank you" even a careless.

But I have an advantage, can overcome careless one, that is a must, please

carefully miss determination, I must get rid of this term with the bad habit of

my 11!

In to talk about my study, I is not very good students in the class,

because my language result, combined with my memory is not very good, sometimes

language examination have words cant write, I be untouched, verse forgot, I when

the poet, read the topic not, Ill be imagine writer. English? Sometimes the

exam, my Chinese is good, why? Because I always can get pinyin instead of

English words, let the teacher in distress situation.

But I am naturally happy, often can give students bring happiness, if there

are students angry, I can in a minute let his mood by Yin clearing up!

Look, this is me, a advantages disadvantages coexist me.

我，一个短头发的女孩，在父母的精心呵护下，今年以满11岁了。

伴随了11年的缺点：粗心大意一家，害我害的最苦，他让我与一百分擦肩而过，让我错了一道39+26的加法计算题;让我把加号看成了减号，除号看成乘号;让我在语文课上竟然拿出数学书;他甚至还想让我把数学作业写在语文本上!我这些年受够了他的折磨，决心要把他赶出“家门”。

就在近几年，粗心大意一家心血来潮，让我把眼睛大意成了快三百度的近视眼，从此纠缠眼镜，便成了我形影不离的“好朋友”，这还要“谢谢”粗心大意一家。

但我有一个优点，可以治服粗心大意一家，那就是一颗一定要请来细心小姐的决心，我一定要在这学期改掉陪伴我11的坏毛病!

在来谈谈我的学习吧，我在班里不算很优秀的学生，因为我的语文成绩一般，加上我的记忆力不太好，有时语文考试遇到字不会写，我就当造字人，诗句忘了，我当诗人，阅读题不会了，我就当想象作家。英语呢?有时考试的时候，我的语文就好了，为什么呢?因为我的英语单词总能拿拼音代替，让老师哭笑不得。

但我天生快乐，常常能给同学们带来快乐，若有同学生气了，我能在一分钟之内让他的心情由阴转晴哟!

瞧，这就是我，一个缺点优点共存的我。

Thank you--My Best Friend

Three years ago, I was a cool and detached girl. I never helped others or cried, because i thought that was very boring.

One day an unusual girl rushed into my life. She looks like a boy and she is also very lovely. She is very cheerful. I always feel she is a "red sun". She is the most beautiful girl that I have ever seen. she often helps me and plays with me. We became good friends at once. Since then, I have been sanguine.

Now, I am still a happy girl. Im often moved by the world. I think our life is so short, and it isnt easy for people to live in the world. Ive learned to help others and to cry. Ive also learned to be happy and grateful. I also understand that crying doesnt mean "coward", crying can mean "visualize a bright future!"though she has lots of new friends and i have many too, she will be my best friend forever, because she has taught me a lot…

Thank you--my best friend!

谢谢你，我的朋友

三年前,我是一个很酷的和孤独的女孩。我从不帮助他人或哭,因为我觉得很无聊。

一天,一个不寻常的女孩冲进我的生活。她看起来像个男孩,她也很可爱。她很开朗。我总觉得她是一个“红太阳”。她是我所看过最美丽的女孩。她经常帮助我和我一起玩。我们成了好朋友。从那时起,我一直乐观。

现在,我还是一个快乐的女孩。我经常感动世界。我认为我们的生命是如此的短暂,这不是一件容易的事,人们生活在世界上。我学会了帮助他人,哭了起来。我也学会了快乐和感激。我也明白,哭并不意味着“懦夫”,哭能意味着“可视化一个光明的未来!“尽管她有很多新朋友,我也有很多,她永远是我最好的朋友,因为她教会了我很多…

谢谢你,我最好的朋友!

The summer vacation is here, and the students are very happy. Now I will

introduce to you how my summer vacation was spent.

When I started to do my homework during the summer vacation, I was always

afraid that I would not finish it. As a result, on July 15th, I was almost

finished. After a few days, the rest of the homework was finished, and there

were only two essays left. I didnt write until August 14th. Next week, my

parents are going to take me to play for two days. I am very happy. Summer is

almost over and I really wish it would be longer.

The summer vacation is almost over, and I have something to worry

about.

Its just that I havent written an essay yet. The school will start soon,

when will I write? In ancient times, people often said: The young and the strong

do not work hard, and the boss is sad. We want us to cherish time, but if I am

different, I will waste time. I am lazy. I hope this shortcoming can be

corrected. I hope you can support me a lot!

Today is the first day of my learning to swim. Before that, I prepared some

necessary things for swimming, such as swimming caps, swimming trunks, swimming

goggles, etc., and I was excited for several days, looking forward to todays

arrival.

When I came to the swimming pool of Baolihao Fitness Center, I saw that the

water was clear and clear, and it could be used as a mirror. I was in a group

with three other children, who, like me, came to study on the first day. Our

main task today is to practice holding and breathing. Yutian, I have never been

in contact with water, so at first I was afraid to hold my breath because of the

water, but when I saw everyone elses head sinking, I mustered up the courage to

sink my head, but it took less than six seconds to come out, and the other

students It took me about 30 seconds to hold back. It seems that I have to do my

best.

When I got home, my mother told me that I have to be determined to do

anything. Since I have gone to learn, I must learn it. If some movements are not

in place, I must find a way to practice more. I think what my mother said makes

a lot of sense, so I practiced holding my breath in the washbasin at night. It

lasted for more than 20 seconds at most. It seems that as long as I work hard, I

can do better. If there is a will, things will come true !

我叫郜文璠，是个女孩，个子不高，前额略高，鼻子微微翘起，显出几分灵气。

从小爸爸妈妈什么事都依着我，天长日久渐渐地养成了爱发脾气的坏习惯，稍有一点儿不称心，就对爸爸妈妈脾气。记得有一次，已经九点多钟了，我做完作业，就去看电视，妈妈不让我看，把电视关了。我才不理她那一套呢，又把电视打开了，就这样，妈妈关，我开，来来回回好几次。妈妈终于发火了，大声说：“你真不听话，给我出去”。我听了，瞪了妈妈一眼，推开门就走了。最后，还是妈妈把我给拖了回来。你们瞧瞧，那个时候我的脾气是什么样子啊！

我渐渐地长大了，脾气也好了很多。我还有一个爱好——看书，一放学回家，就拿起书看。我看的书加起来，是我身高的好几倍呢！够不上书呆子，也算得上小书迷了。

看书使我增长了知识，开阔了眼界，增强了想像力。去年在学校的作文比赛中，我还获得了一等奖呢！这就是我。

这是一个调皮，好动，聪明的小男孩，一天到晚他不被妈妈批评一顿是不会罢休的。你想知道他是谁吗？那就是我。

我姓杨，名廷玉。“廷玉”顾名思义，就是门廷中的一块美玉。孔子曰：君子比德如玉，玉之五德，仁义智勇洁。舅舅和爸爸妈妈希望我有像玉一样的五德，表里如一，百折不挠，不以暴制暴。

你想知道我长什么样吗？那我就告诉你们吧！我有一头乌黑的短发，一对大刀眉，沉思时，眉头一皱，皱纹形成了“川字，眼睛小而有神，像镶了两块黑宝石似的。鼻子塌塌的，有一张樱桃小嘴，说起话来井井有条，头头是道。一对“招风耳”矗立在头两边，“隔山相望”。

告诉你一个小秘密，说我聪明，其实我是个“马大哈”。

有一次，做奥数题，做十道错九道，全是计算错误，本子上几乎是错号满满，把妈妈气得怒目圆瞪，连声说道：“无可救药，无可救药。”并狠狠地批了我一顿。唉！那些红艳艳的大错号，好像是深深烙在我心中的印记。大家可不要学我哦，这可是学习中的大忌。

我虽然是个“马大哈”，可是我也是个“聪明蛋”。做奥数题可是我的拿手绝活。有一次我在书上遇到了一道奥数题，我看了两遍就一目了然了，直接写出了答案。妈妈检查作业时，冥思苦想了半天也没有想出个所以然来，最后还得请教我啊！

这就是我，优点和缺点集于一身，让人又爱又恨的我。

因为人的记忆力有选择啊，有的人天生对语言天生敏感，所以记得就快，有的人对历史敏感，记忆历史就比别人快。所以人的记忆力不能一概而论，这是我多年学习的经验，和个人理解。

第一，你不要把英语单词当成中文的象形文字来记，中文的记忆有形象关系，但是单词时无意义的字母排序，背得时候一定要理解英语的发音规律，先要记没个单词的发音，有的发音如tioneror什么的你一定发现了几个字母组合法特定的音，按发音记！

有时候宁肯先记发音！

因为有时候，你甚至能根据发音，你自己就能写出来，何必要背。其实英语的字母单词，不是很规律的，不想拼音的，但还是有一定的规律。

其实背英语单词，不能死记是真的，但是一定要持之以恒，首先要有心理准备，要有自信。

你背英语单词的时候可以边默读便用笔在一张纸上写，就是随便写一些，主要是加深印象。

我的习惯是第一次背时先写5遍/单词，隔天写3遍/单词。过一段时间再重复。这样记虽然慢，但是很扎实。

而且还要注意，背单词应该背词典，就是你背一个词的形式，比如名词，最好翻阅词典，把其他的形式也给背过。这样看起来，似乎比较费脑子，实际上我认为，这样无形中很快，因为你背单词就是要用在阅读上，这样背的话既实用又能无形中体会出英语的变形规律，以后就会背的很快乐。

英语背单词，实际取决于你已经背的单词量。

不是英语专业的人，但是愿意分享我的经验，希望你能背得越来越轻松。

i am xxx. i was born in xx. i graduate from senior high school and major inenglish. i started learning english since i was XX years old. my parents have alot of american friends. that’s why i have no problem communicating withamericans or others by speaking english.

in my spare time, i like to do anything relating to english such aslistening to english songs, watching english movies or tv programs, or evenattending the activities held by some english clubs or institutes. i used to goapoad for a short- term english study. during that time, i learned a lot ofdaily life english and saw a lot of different things.

i think language is very interesting. i could express one substance byusing different sounds. so i wish i could study and read more englishliteratures and enlarge my knowledge.

生活中，一抹鼓励的微笑，一句感动的话语，一个熟悉的动作都像阳光一般温暖我的心头。 In life, a touch of encouragement, a touch of words, a familiar action is like the sun that warms my heart.

曾记得2018年的第一场雪到来。我想堆个雪人，于是约上了左邻右舍的小伙伴。好不容易做好了，可是由于我们的疏漏雪人头掉了下来，我正准备放弃，妈妈走过来对我说：“创造美是要付出努力的，只是一个头摔碎了，重新再做一个就行。好好想一想，雪人的头为什么会落下来呢?还是你们的设计有疏漏啊!”说完还对我们微笑以示鼓励。

这抹微笑像阳光一样照耀在我原本郁闷的心头。我一番思索豁然开朗，重新做了一个十分完美的雪人。这抹能改变人心情的阳光，我将永远珍藏。

曾记得在和婷婷老师分别的那一天。她对我们说：“我虽然跑得不快，但我是最努力跑的一个。我虽然跳得不高，但我是最努力跳的一个。我虽然成绩不好，但我是最努力学的一个。”婷婷老师的这番鼓励使我原本已经被冰川覆盖的心像阳光一样被照耀，我不禁头涔涔而泪潸潸了，每当我付出和收获不成正比的时候，我都想起婷婷老师的这番话。我要将这缕阳光永远珍藏。

曾记得那个冬天我看到一个青年摔倒。我嘲笑他：“大小伙子，还摔跤!反正，我应该是不会摔倒的。”可是就在我刚说完这句话的时候，我就啪啪打脸了——我也摔了个四仰八翻。当个场面至今我记忆犹新：那位青年走近我，将我扶了起来。“你……”我为刚才嘲笑他的行为感到羞愧，我嗫嚅着。陌生人友善地拍拍我的肩，用力地握了握我的手，什么也没说，走开了。残留在手上的余温让我明白了：宽容友善是和谐社会的黏合剂。我要将这陌生人的温暖永远收藏。

在过去的四千多日子里，阳光陪伴着我成长，我将永远珍藏;同时，也时刻提醒自己：做一个播撒阳光的人!

我们生活的世界就似一个百花园，每个人都是这个花园里的一朵花。“人与人不同，花有百样红”，我们每个人都有自己的性格。兴趣。爱好。特长……下面，我就来介绍一下自己吧！小小的眼睛，乌黑的长发，一张樱桃小嘴，能说会道。这就是我。

我有一个缺点：爱哭。谁要是惹到我，我的眼睛就似没关紧的水龙头，眼泪哗哗的流个不停，唉！其实我也不想当一个娇里娇气的女孩，可是，我也关不住这个水龙头。

记得有一次，是在放学的路上，我们班的某一个女生，不小心撞到了我的耳朵，把我的耳钉撞掉了，耳朵还流血了，我便大哭起来，我们班的几个女生都在安慰我，可是，她们谁安慰我都不行，我就是哭。

我还有一大优势：有恒心。

这天，我和我的朋友一起剥花生，开始，我们觉得这是一种乐趣，就开始高高兴兴的剥了起来。可是，我们还没有剥到一半，我们就觉得没意思了，我的朋友便去看电视了，正在我想走进屋里看电视时，我的耳边就回荡起了妈妈的这句话：做事情要有始有终，有恒心。然后，我又坐在这里剥起了花生，最后，我坚持下来，终于，慢慢一盘的花生便呈现在我的眼前！这是对我恒心的一个小小的考验。我看到了我的大海，我看到了我的成果，我好高兴！

这就是我，一个既爱哭，又有恒心的可爱的小女孩。

我叫刘x，今年10岁了，是个男孩，属猴。在东风路小学上学，我是一个喜欢说话的孩子，我一喜欢看一些课外书。我长着一对大眼睛双眼皮，两颗眼珠像两颗黑葡萄一样。因为我有一个大圆脸，所以班里的同学给我起了一个外号，“猪八戒”。但是我虽然吃的多，但消化不好也不胖，我也没那么笨，所以我感觉这个绰号不合适。我还是一个喜新厌旧的小男孩，不信，你看看下面的是你就知道了。

那是我一岁多快两岁的时候，那一天我的凉鞋的鞋底坏了，妈妈和爸爸就骑着摩托车带着我去买鞋了，我当时可能知道要去买鞋了，就对妈妈说：“妈妈，我要把鞋脱掉，然后扔了。”妈妈笑着说：“你个小淘气包，知道要去买新东西了就要把旧东西给扔掉，你可真是个喜新厌旧的小男孩呀。”说了那么多，你先把我的鞋扔了在和我聊天。妈妈无可奈何的把鞋藏到背后不让我看见，但是我一会就找到了，死活要把鞋扔了，妈妈只好让爸爸停车，下去之后把鞋装到了后背箱里，但是，这还是被我识破了。我妈妈就对我说：“你把鞋留着，回去卖钱，卖的钱给你买冰激凌吃。”我一听，喜了，就高兴的答应了。我不仅是个喜新忘旧的人，还是一个心软的人，那一次让全家人哭笑不得。

那时我才三岁，还在上小班的时候，我刚学会两个英语单词，一个boy，一个girl。有一个小女孩，打了我一下，我没有还手，她还以为我不敢打她，就又打了我几下，我身上一经红的红紫的紫，流血的是流血，但还是没还一次手，回到家，我哇的一声哭了起来，姨姨、爸爸、妈妈、姥姥、姥爷都关心的问我是怎么回事，我哭着说：“有一个女孩打我。”确实有伤，我姨姨就问我：“你为什么不打她?”我说：“我是boy，她是girl，boy是不能打girl的。”正是这样，我被她打伤了好几次。但如果是男孩的话，我就会毫不心软的把他打趴在地。是因为这种性格，所以才给我转了幼儿园。

每个人都有性格，我的性格是不是很搞笑呢，你呢?

There is an English saying.It says,"Early to bed, early to rise, makes a

have enough time to sleep.We should sleep for 8 hours every day.So we must do

our homework quickly and go to bed before 10 p.m.Proverbs can always give us

As a student in Yibin, we should behave well.

First, I think it’s very important to do everything on time and keep promises. Never lie to others or say dirty words. Next we should be polite to others and ready to help people in need. Then we’d better not talk loudly in public. Don’t throw litter or spit about. And remember to obey traffic rules.

Finally, learn to work with others. We need good team work in our life.

我是一个比较有自信的孩子，从上小学到现在，学习一直优秀，每次考试成绩都是名列前茅。

每次考完试我都要进行总结，都要找一下错了的题的原因，找一下自己的不足，在以后的学习里注意。

老妈经常对我说：“侯翔，你一定要努力学习，在考试的时候，你考好了不要骄傲，考不好不要灰心，你要经常找一下你的缺点与不足，你就有成功的希望！做好完美的自己，你就会在将来的道路上立于不败之地的！”老妈的话经常在我耳畔响起，作业做错了我要找原因，上课的时候遇到错题我也要找原因，经常因为一道错题浪费我的好长时间，但我从没因为错题做不出放弃。实在不会的找老师问，不懂的地方一一给老师指出来，直到懂了为止。因为我的认真，老师也拿我没辙！

小升初我过于大意，考了我们班第十名！升入初中以后，我并不灰心，我觉得我有能力赶上或超过在我前面排名的同学。进入初中我就用实际行动去面对我的竞争对手，由于我的努力，每次考试我都要前进一步，这一学期，我给初一画上了一个完美的句号！

我的成绩：语文89、数学98、政治100、历史100、地理100、英语100、生物100，全班第一，全年级第二！

公布成绩以后，我心里甭提有多高兴了，可我还是觉得自己有不足的地方，数学那道扣了2分的题我是会做的，只是当时一下想不起来，想留在最后再做一下，可气的我做完题以后忘掉了，把卷子交了上去。语文由于我的疏忽，扣掉了本来不该扣掉的分，我要吸取这些教训，在以后的学习上一定注意。我相信，我会做好的！只要有付出，就会有成功的！

It is the day that the families get together.

The spring festival is usually in the February ,sometimes in January.In the spring festival,every family all paste the lucky inscriptions,they fire the cracker,they eat the dumplings.The day before the new years first day is the new years eve,same as the christmas eve,all the families get together to have the new yaars dinner,wishes each other,talk about the wishes about the new year.Small children will receive the money given to children as a lunar new year gift.

My name is xxx.  There are 4 people in my family.  My father is a Chemistryteacher.  He teaches chemistry in senior high school.  My mother is an English teacher.  She teaches English in the university.  I have a younger brother, he is a junior high school student and is preparing for the entrance exam.

I like to read English story books in my free time.  Sometimes I surf the Internet and download the E- books to read.  Reading E- books is fun.  In addition, it also enlarges my vocabulary words because of the advanced technology and the vivid animations.

I hope to study both English and computer technology because I am interested in both of the subjects.  Maybe one day I could combine both of them and apply to my research in the future.

丝瓜花，南瓜花，人家不夸我自夸。嘻嘻，这是我编的广告词，好听吧!

徐释迦，就是我的鼎鼎大名。你们可能会想，做父母的怎么给孩子起这个名字?别急，别急，请往下看。因为爸爸信佛，最沉迷释迦摩尼，所以给我起了这个名字。

我的性格很活泼，也比较任性。有一次，我作业写完了，想去新华书店看书。妈妈却说：“写完一篇日记再去!”“我不管，我不写，我要去看书!”我答道。“啪!”妈妈给了我一记响亮的耳光。我这个人是好了伤疤忘了疼。一个星期六，我疯玩了一天，回到家，妈妈凶巴巴地看着我，说：“你上个星期不是答应我星期六做完作业，星期天玩的吗?怎么反悔了?”“我……我……”后面的情节大家一定想得到吧!

我喜欢打扮。有一次，妈妈有事出去了，我便拿出“文房四宝”——妈妈的高跟鞋、化妆品、项链、手镯，打扮起来。打扮完后，我照了照镜子，觉得脸上还不满意，于是又画了画。这次画得可好看了，白里透红的小脸上，一张樱桃红的小嘴。我对着镜子看了又看，心里别提有多美了!

我的爱好很广泛，最爱转呼啦圈。有一次，学校搞活动，我在活动中表演了转呼啦圈，老师和同学都拍手叫好。

丝瓜花，南瓜花，人家不夸我自夸。你们喜欢我吗?
