初中英语日记20篇带翻译热门20篇

This morning, my father took me to school by bike. I sat at the back of the

bike, eating a banana. After I ate it up, I threw the skin onto the street

randomly.

今天早晨，爸爸骑车带我去上学。我坐在后车座上，吃着香蕉。吃完后，我顺手将香蕉皮扔到了街上。

No sooner had I done this than I realized that I had done something bad to

our environment. And maybe someone would step on it and tumble over. I must pick

it up. Thinking of these, I asked father to stop. I jumped off the bike and ran

back to pick up the banana skin and threw it into a roadside dustbin. Seeing

this, father praised me and I felt very happy.

我马上意识到我的所作所为破坏了我们的环境，或许有人会踩在上面而跌倒，我必须把它拾起来。想到这些，我让爸爸停车。我跳下自行车，跑回去拾起香蕉皮，并扔到了路边的垃圾箱里。看到这些，爸爸表扬了我。我感到很高兴。

In future I will protect the surroundings more consciously and think more

about others.

将来我要更自觉地保护周围的环境，更多地为他人着想。

Smoking And Health

Today smoking is a widespread habit ali over the world. Not only the old,

the youth, but also middle school students have been engaged in smoking. Many of

them think that smoking is a smart symbol.

However, smoking is harmful to one’s ,health. It contributes a lot of lung

cancer, from which many people have died in the past years. It can also cause

many other diseases. In a word, if you smoke, you do have a much greater chance

of losing your health. Furthermore, scientific research shows that smoking is

not only harmful to smokers themselves, but also a threat to public health,

especially to women and children. Therefore, many countries have made laws

forbidding smokers to smoke m public places such as cinemas, stations,

hospitals, and so on Giveup smoking! If you don’t smoke, don’t start. Give

upsmoking for the sake of your health, for the sake of your family, and for the

sake of the whole world.

吸烟与健康

现在，吸烟是一个世界范围的习惯，不仅老年人、青年人吸烟，就连中学生也加入到这个行列中来，他们中的许多人认为吸烟是一种潇洒的象征。

然而，吸烟对人的健康是有害的，它会引起肺癌，在刚刚过去的几年中;许多人因此而丧命，还可能引发其他的疾病。总之，如果你吸烟的话，你就很可能失去拥有健康的机会，更进一步说，科学研究显示，吸烟不仅危害吸烟者本人，而且对公共健康来说，也是一个凶兆，尤其是对妇女和孩子。因此，许多国家都制定了不准在公共场合吸烟的法规，例如：电影院，车站，医院等地。

戒烟吧，如果你还未染上，请不要开始;戒烟吧，为了你的健康，为了你的家庭的健康，为了整个世界的健康。

I used to think Beijing must be a grand and special city, given that it was the capital of China, and lots of events I have heard took place there. But soon after I got off the plane, I knew all was but my illusion. If I had to use one wordto describe it, nothing but “grey” will fulfil the task. As far as your eyes could see, all was covered in dust and haunted by air pollution.

Though it was the first time I had been to the North part of China, I was still surprised by the sharp contrast between the South and North. It wasnt hearsay.

我曾经认为北京必须大,特殊的城市,因为它是中国的首都,我听过很多事件发生。但很快我下了飞机后,我知道一切,但我的错觉。如果要我用一个词来描述它,除了“灰色”将完成任务。你的眼睛可以看到,一切都覆盖着灰尘和被空气污染。

尽管这是我第一次被北中国的一部分,我还惊讶南部和北部之间的鲜明对比。这不是道听途说。

Nowadays, with the development of technology, the market competition is

fierce and people feel great pressure. In order to improve the working

efficiency, they force themselves to work overtime. However, they are not

machine and need to slow down life pace, or they will break down sooner or

later.

We cant slow down the working hour, but we can control our private time. A

lot of young people mix with working time and private time, so they cant enjoy

their life and feel depressed all the time. The smart person will find the

balance. They will put aside the working stuff when the clock tells them that it

is time to be off work and find the way to release their pressure, such as

KTV.

Spending the time with friends and families is always a good way to enjoy

our time. No matter what kind of difficulties we face, when we recall of these

happy moments, we will have motivation to move on. We cant choose everything we

want, but we can adjust ourselves to the environment and keep the good mood.

Once life pace slows down, we control our life.

On the fourth Thursday of November, Thanksgiving Day, I made an envelope on

the day of Thanksgiving, which read: the gift that wang xiyuan gave her. Inside

with a small piece of paper, it read: your mother is my ents, I like a small

tree, you help me with the scissors with branches that bad, let me grow up

faster, thank you, mom. My mother put me in my arms and said, jia jia is

sensible! Im so happy.

I gave my dad a paper airplane that said, "the gift from wang xiyuan."

There was also an envelope in the suture of the paper plane, and there was a

note on it that read: daddy happy Thanksgiving, father surprised and a sound,

said: my jia jia grow up! I smiled and walked into the study to play two

childrens songs for mom and dad. It was little red riding hood and the golden

peacock. A sweet piano. The whole familys laughter echoed in the real room.

Students, how do you spend Thanksgiving? Tell me about it!

我们每一位生物教师应不断转变教育观念、更新教育思想、改革教学模式、改进教学方法和手段,适应新课标的要求。生物新课标要求我们制定每节课的教学目标时，要注意培养学生的科学素养即三个维度——知识、能力、情感态度与价值观。

一、知识性目标的反思

根据新课标的要求，制定知识目标。扎扎实实抓好生物概念、生物规律等基础知识的教学，在具体教学中，要搞清生物要领的形成过程，讲清生物概念的定义、含义及特性等。知识的学习笔者大多是利用问题激发学生的互动学习。例如第五章植物的呼吸作用及其利用，围绕三个问题导入：1.什么是呼吸，请说出你身边的呼吸现象?2.人或动物在呼吸时，吸进的气体与呼出的气体在成分上有什么不同?3.植物有没呼吸?等问题展开互动交流讨论。有位学生提出应该用什么方法来证明氧气或二氧化碳的存在?教学内容就这样自然的延续。

二、技能性目标的反思

生物课堂教学应理论联系实际，注重应用，这既是生

物学科特点的必然体现，也是适应素质教育的迫切需要的表现。在课堂教学中，教师应尽量列举身边的生活、生产中的实例，向学生介绍现代科技知识，这样可以开拓学生的视野，提高学生认识问题和解决问题的能力。

教材要求的分组实验有具备条件，一个个都要开展，实验过程注重学生实践能力的培养。七年级开展的用显微镜观察人血涂片实验，发现学生动手能力很强，出乎意料，对实验也非常感兴趣，当场给以表扬。当然对学生的肯定对帮助学生确立自信也是很有帮助。加强课堂演示实验教学，激发学生的学习兴趣。

三、情感态度与价值观的反思

情感态度与价值观必须有机地融入到课程教学内容中去，并有意识地贯穿于教学过程中，使其成为课程教学内容的血肉，成为教学过程的灵魂。在学习七年级植物标本的采集过程中，“同学们植物标本可帮助我们认识多种多样的植物，在科学研究中也占有重要的作用。那么我们该为植物做些什么呢?”“请我们大家一起来爱护花草树木，以后不会再出现有的同学践踏学校的草坪这现象。”学生也意识要爱护一草一木。

My home town is a beautiful place. It stands beside a wide river and is

rich in fish and rice.

But in the old days it was a poor and backward little town. Many people had

no work. They lived a hard life.

In 1949 my hometown was liberated. Since then great changes have taken

place there. The streets have been widened. Factories, schools, hospitals,

cinemas and theatres have sprung up one after another. The life of the people is

greatly improved.

I love my hometown. All the more I love its people. They are working hard

so as to make it still richer and more beautiful.

狂人日记是中国现代文学史上第一篇真正的现代白话小说。令人惊异的是这部中国现代小说史上具有开山意义的作品。狂人日记最初进入视野的是“狂人臆想的世界”。狂人发病枣旁人侧目枣家人延医救治枣狂人复原。这一层的意思凡识字者均可以解读出来。因为小说的“序”中清楚地交待了：某君昆仲今隐其名。皆余昔日在中学时良友。分隔多年。消息渐阙。日前偶闻其一大病。适归故乡。迂道往访。则仅晤一人。言病者其弟也。劳君远道而来视，然已早愈。赴某地候补矣。我们所看到的“狂人日记”就是这样一个医学上的病例的记载。由于鲁迅曾经学习过医学，并且护理过患精神病的家人。因此这份“狂人日记”模拟得十分真切，详尽。

大多数人都可以很轻易地透过病例的遐想。看到鲁迅以象征的形式对封建传统所进行的批判枣在这里。我们就开始了解狂人眼中的世界真相：狂人忽然醒悟“传统”杀人。吃人的罪恶枣周围人无法容纳清醒者开始对对他进行迫害。

在不同的时代中，不同的读者将会有不同的理解读出现。对人类整体的批判也并非鲁迅创作时清醒的本意。但狂人眼中的常人世界却具有广阔的共时性和世界性。因而其批判便决于仅止于五四前的中国国民而可以延伸到整个人类其批判所指的人类劣根性也不是仅仅消灭“封建文化制度”并可以根除——也许它本就是人类基中根深蒂因的一个分子。永远无消除，并将在最终导致人类的自我毁灭。这征兆，我们在今天已经可以看出，可以球毁灭几千次的武器。每个人都参与其中的对地球的污染。因人类道德论丧爆发出来无法治愈的世界疾病“爱滋病”鲁迅正是因为看到了人类的这种难以根除的劣根性，因此才感到深深的绝望。“救救孩子”的呼声之后才不是一个“感叹号”而”省略号“，在他看来这呼声俨然如将封建闭在天法打破的铁屋子里的将死之人唤醒。

使他们感到天法解脱的痛苦。然而鲁迅始终是一位真面现实的勇士。即使他内心中已经感到绝望却仍然站起来进行绝望中的反抗。而这种”知其不可为而为之“的精神在今天也并非全部灭绝，因此我们可以看到已经有人唤吁保护地球。建立绿色家园，寻找人类的终极价值。虽然这呼声十分微弱，但却令人看到了人类世界的最后曙光。

Today is the day, the sky cloudless, I am confident, and mom and dad to learner.

To the river, dad went fishing, mother accompany me to learn the bike.The first thing I will left foot across the bicycle, step on the pedal, after stand firm.Right foot on the right pedal slowly again.Is not good, because they dont balance, so I nearly fell down.I passed the practice again and again, I finally learned to bicycle, but the to panic when a sharp turn, bumped into a wall with a thud, constantly thinking after I go home.In the end I came up with a good solution.But I took a ride, in;Turn a body the diagonal, in the past.I made it!

I go fishing in the second home, because mom and dad riding electric cars, so I had been dumped down, my in the mind a nasty, accelerate forward.Results had a fall, but have no pain.After a while, father ride away, so I had to sit on moms storage battery to go home.In the winter vacation, I help mom and dad to buy food, buy salt, mom and dad kua I good helper.

I am here to everyone happy New Year.I wish you all in the auspicious, happy New Year!

今天是大年初一，天上万里无云，我信心满满的和爸爸妈妈去学车。

到了河边，爸爸去钓鱼了，妈妈陪我学自行车。我首先将左脚跨过自行车，踩在脚蹬子上，站稳后。再慢慢将右脚踩在右脚蹬子上。不好，因为不平衡，所以我差一点就摔倒了。我经过了一次又一次的练习，我终于学会了自行车，可是在急转弯时却慌了手脚，砰地一声撞在了墙上，我回家后不停的思考。最后我想到了一个好办法。我又却骑了一次，在;急转弯时身子一斜，就过去了。我成功了!

我在第二次钓鱼回家的时候，因为爸爸妈妈骑的是电动车，所以我被甩了下去，我心里一急，就加速向前冲。结果摔了一跤，但一点儿也不疼。过了一会，爸爸骑上车走了，我只好坐在妈妈的电瓶车上回家了。寒假中，我帮爸爸妈妈买菜、买盐，爸爸妈妈夸我好帮手。

我在这里给大家拜年了。祝大家羊年吉祥、新年快乐!

Some people say， “Money is more important than time。” Some say， “We can buy

everything with money。” For some people， money is everything。 They think they

can buy everything they want， including time。 Do you think so? No。 I don’t think

so。 Because when money is spent， we can get it back。 However， when time has

gone， it will never return。 Nevertheless many of us always waste time and put

off today’s work till tomorrow。

In fact， time is more important than money and time never stops for anyone

or anything。 For everyone， time is so limited that if we waste our precious

time， we won’t get it back。 Therefore， we should save every second we own and

make full use of our time to study hard。 The harder we work now， the more we

will get in future!

Let’s save time together!

I think my teacher got out of bedon the wtong side this afternoon as she

这也是一个快乐的日子，是不是?

Today, my parents were not at home, they had something to deal with, so

they left me alone. I was so happy because I could be in charge in my own house,

it made me feel like I was a grow-up. I wanted to give my parents a surprise, so

今天是大年三十，除夕夜。家家户户都是一家人坐在一起吃年夜饭。

Today is thirty of the year, new years Eve. Every family is a family sitting together to eat a years dinner.

没吃一会儿门外就响起了“噌……碰”或者“啪啪啪……”的声响，我们一家人放下碗、筷，跑到门口看，这是哥哥说了一句话：不如我们也拿几个烟火出来放吧！我们所有人点头表示同意。我们将烟火放在门前，哥哥走到烟火旁用打火机点燃，便马上跑了回来。我听见“噌……”的一声就回过头来看，只见一朵花，无颜六色：红的象征着喜庆，蓝的象征着智慧、绿的象征着生机、黄的象征着温暖、紫的象征着浪漫……一会天女散花，一会枪林弹雨，七色的小球一颗颗落下，犹如一道彩虹。这是几乎所有的人家都开始放烟花了，一瞬间天空变成了烟花的海洋，各种色彩，各种样子，都在天空中绽开。快乐的寒假作文200字

Be Grateful to Our Parents

I consider my parents as the most important people in my life. This is not because they re wealthy or famous. Rather, what I value about most is the care and love they show to me.

我认为我的父母是我生命中最重要的人.这并不是因为他们有钱或有名的.相反,我最珍惜的是他们给我的关心和爱..

My parents might work hard, but they re always there for me. Whenever I get into trouble and desperately need a hand, they come over first to support me and encourage me. I grew up with their constant care and love. While they re getting older with grey hair and wrinkles, they never lose dignity in both life and jobs.

我父母虽然努力工作,但他们总是陪在我身边.每当我陷入困境,迫切需要帮助时.他们是第一个支持我、鼓励我的人.我在他们不断的爱和照顾中长大.当他们变老而且出现白发和皱纹时,他们也永远不会失去生活和工作的尊严.

From my parents, I have learned that one person can really make a difference. I ll never forget their care and love. Gratefulness brings a great fullness to life. I wish they could always be happy and healthy. It is high time we expressed our gratitude to people we cherish!

To tell you the truth, I dont like the Spring Festival at all. When I was

young I liked it very much,because I could had something tasty to eat during the

Spring Festival,and I could enjoy very wonderful TV programmes,too. I also could

had much free time during which I could did something I liked to do. I dont

like it now, there are many reasons.

Firstly, I cant have a good time during the Festival. Every New Years Eve

something unpleasant often happens. Once I quarreled with my second brother.

Secondly, I cant relax myself during the Festival. I have to do many

things, watch so many TV programmes, meet so many people,all these things make

me very tired.

Thirdly, spending one Spring Festival means that I become one year older. I

dont like to be old. I want to live longer and be young all the time.

Readers, what is your opinions about the Spring Festival? Please tell us,

we can share our opinions. Thanks for reading! Goodbye.

参考译文

说实话，我一点都不喜欢春节。不过我年轻的时候，我非常喜欢，因为我可以在春节吃到美味佳肴，我可以享受到非常精彩的电视节目。我还可以有很多自由时间来做我喜欢做的事情。现在我不喜欢了，有许多理由。

首先，在节日期间我玩得不开心。每年除夕夜总有不愉快的事发生。有一次我跟我的二弟吵架。

其次，在节日期间我自己无法得到放松。我要做很多事情，看很多的电视节目，见很多的人，所有这些都让我感到很累。

第三，度过一个春节意味着我又老一岁了，我不喜欢老。我想活得更久，并且永远年轻。

读者们，你有什么关于春节的想法吗?请告诉我们，我们可以分享我们的想法。感谢您的阅读!再见。

I think I will be an interpreter, because I like all kinds of the languaes.

Of course, I may be a businessman . Because I like biz,too. I will have a villa

and a robot. In ten years, My parents will have hoary hair and rimple. And I

will be more mature than now. I will be more disengaged than now, too. My family

will be richer and richer.

我认为我将会作为一名翻译,因为我喜欢各种各样的语言.当然,我可能是一个商人.因为我喜欢,真是太好了.我将会有一幢别墅和一个机器人.在十年内,我的父母会有花白的头发和rimple.主耶和华如此说、我将比现在更加成熟.我将会有更多的空闲比现在也是.我的家人会越来越丰富.

August 25 2014 Thursday Sunny

I am very happy today.

Today I have received the highest honour as I obtained full mark and finally beat Xiaoming in the English test.I have been famous for my ability of studying English and eventually I showed my true power today.Those people who are gossiping behind my back should shut up now.

After school,when I went home, I found a hundred dollar notes.Somebody must have been careless and dropped them.Since this is a deserted road,I would not bother returning the money as I had nowhere to go to.

Then,I helped a blind uncle crossing the road.

I feel that I am really delighted.

[初中英语小日记

初中生物实验教学实施素质教育的目标是培养具有较高的科学素养、具有科学的思维和研究方法、具有创新意识和创新能力的人才。生物实验教学是培养学生观察能力、动手操作能力、推理分析能力和创新能力的重要途径。那次，在教学中，可以通过实验强化学生思维意识和动手操作水平，从而达到培养学生的创新和创造能力的目标。下面就一下几方面谈一下关于生物实验及创新的认识。

一、认真备课，掌握步骤和要领

教师在备课时应先做好实验，分析实验步骤。实验步骤是学生动手规范操作的要领,只有理解、掌握才能规范操作,实验才能成功。因此实验前指导学生预习,将实验步骤由繁化简,抓住每一步的关键词语串通于实验步骤之中，可以收到好的实验效果。

例如，显微镜使用过程中的“三个一”:一、安放距桌边一掌(5-7cm);二、对光要目(目镜)物(物镜)通光(通光孔、光源)一直线,光强用平面镜,光弱用凹面镜;三、观察时标本对孔正中距离物镜一厘米,视野中出现标本颜色或杂质时观察目标即将到位,微调粗旋镜升降,细旋校象清晰,找不到目标时缓缓移动玻片标本即可找到。操作时用左眼观察时,同时右眼睁开,转动物镜时，应扳动转换器。这样学生很快对好光,观察到标本在视野中的图象。用完显微镜擦干净外表。转动转换器,把物镜偏两旁,放回镜箱原处。

再如，制作临时装片的实验,将实验步骤概括为擦→滴→取→展→盖→染。然后强调注意事项。滴一滴清水,太多易外溢,太少易出现气泡。取材薄而透明透光易观察,展平防重叠,轻盖防气泡。气泡与细胞的区别,气泡呈圆形，边厚黑,中间亮白,轻压变形。这样学生很快掌握步骤、要领,在显微镜下观察到自己制作临时装片中的细胞,认识细胞壁、细胞质、细胞核(细胞膜紧贴细胞壁,在光镜下看不见),然后绘出细胞结构图。这样学生就达到了实验的目的要求,兴奋不已,终生难忘。

二、指导实验，及时反馈和调控

在实验中，教师通过巡视，随时纠正学生的操作错误，及时表扬规范操作快而且准确的学生这是实验过程中的及时反馈与调控。例如，有的学生在实验过程中，急于观察，但未按课本的有要求操作，他们或用高倍镜对光，或光圈反光镜未调好，就急于调整粗准焦螺旋，眯着眼睛看目镜。这时，教师应启发学生对照课本的操作要求，检查自己的操作错误并纠正。学生在独立进行实验操作时，往往心理负担较重，动作技能还没有熟练，出现一些错误是正常的，教师要耐心的支出并给予及时的纠正。实验结束后，对表现好的学生要及时给予表扬，对普遍存在的失误应给予分析和纠正。让学生吃一鉴，长一智。整个过程要处分发挥学生的整体作用，也要充分发挥教师的主导作用。

三、正确处理规范与创新的关系

中学生物实验大部分属于验证性实验。而要提高学生的科学素养，除了掌握课本结论外，还应提高学生的创新与探索意识。教师在实验过程城中，既要要求学生严格规范实验操作，又要引导学生的创新思维。例如，在“练习和使用显微镜”的实验中有些学生会对显微镜感兴趣，除了完成教师规定的操作外，还会放一根头发或一张纸在显微镜下观察，这种做法是对显微镜无损的，。却反映出学生的求知欲，教师不但不应制止，还应当因势利导，让学生说说实验结果，引导学去理解“所观察的材料必须是薄而透明的”。在这一实验中，一些学生会转转目镜、物镜等，此时教师可以提出“如何判断视野中的污点在哪里?”以此来培养学生的发散思维。

四、将某些验证性试验改为探究性试验

探究性试验与验证性实验相比，更能发挥学生的整体作用，克服思维定式的束缚，更有利于学生的探索精神和创造性思维的培养。因此要鼓励学生不迷信权威，大胆探索，大胆创新。例如在“验证人体呼出的气体中含有较多的二氧化碳”时，我就鼓励学生把它变成探究性实验。人体呼出的气体有二氧化碳吗?人呼出的气体有二氧化碳吗?人呼出气体中二氧化碳与空气中二氧化碳含量相同吗?提示二氧化碳能使澄清的石灰水变浑浊。在这一实验中可将打气筒变为吸耳球，考虑到学生没有使用过吸耳球，在实验前向学生出示洗耳球并简单介绍他的作用。然后学生经过讨论、分析制定了下列实验步骤：①取甲乙丙三只试管，分别注入10毫升澄清的石灰水;②用玻璃管向甲试管中吹气，重复几次，一段时间后，发现甲试管中澄清的石灰水变浑浊;③取一只玻璃管插入乙试管中，不断用吸耳球向玻璃管内压气，与向甲试管中吹气的时间相同，发现澄清的石灰水变浑浊;④以丙试管作对照，比较甲乙两支试管，发现甲试管石灰水变浑浊程度深;⑤得出结论;人呼出的气体中含有较多的二氧化碳。

实验的成功与失败都会引起学生注意，进而探索实验材料的选择等，培养了学生的思维能力、分析解决问题能力以及实验创新能力。

生物是一门以实验为基础的学科。在教学中注重实验教学，一定能使我们的教学事半功倍。

In my heart, my father is a great man, he wakes up early and goes to work,

in the event, he goes home late. He is working so hard, all he does is for the

family and to support my education. Once I ask him if he is tired, he smiles and

says that I am his sweet burden. I feel so moved, his love for me is so

deep.

在我心里，我的爸爸是个伟大的人，他很早就起来上班，在晚上，他很晚才回家。他一直都很努力工作，他所做的一切都是为了家庭和支持我的教育。曾经我问他是否感到很累，他对我微笑，说我是他甜蜜的负担。我很感动，他对我的爱是如此的深。

An English proverb says that time is money. I consider it (this) wrong.

Why? Because we all know that we can earn money by work but can not in any way

get back time (in anyway). For this reason, we may (can) say that time is more

valuable than money.Many people do not know the value of time. It (this) is

indeed a great pity. We must bear (keep) in mind that wasting time is equal to

wasting your life.

i read an article today。 it was about how people should try their best to

save water。 water is very important for human being but some people are just

wasting water。 they dont turn off the tap after they finish using it。 we should

do better to save water。
