初二英语上册期中考试作文（推荐20篇）

期中考试成绩终于揭晓了，成绩真的出乎意料，语文83分，数学92分，英语105．5分，政治77，历史86，地理84，生物85。通过这次的考试，我了解到了我的不足之处。

首先我要改掉考试不细心读题目的坏习惯。有时候我往往看着题目前面就顺手把后面的问题写上了，但是却错了很多。这也许也和答题技巧有关系。总之，通过以后的练习，我一定要在考试的过程之中认真审题，自习读题，把题目看准、看好。时间允许的时候要多检查几遍，绝对不允许自己再犯类似于这样的无谓的错误。

期中考试后，每个人都有不同的体会，不同的反思与总结。现在，请牢记住这个习惯，带上你的收获与总结，跨步前行。有更多的挑战等着你，让这次的失败，铸成下次的成功，让这次的成功，铸成下次的辉煌！

今天，我就要期中考试了。我已经准备好了。

写考前的准备，如能把如何准备写得稍详细一点会更好。

我一进考场。监考老师就让我班的同学和我隔一个一坐。这时，铃声响了起来。监考老师就从档案袋里面拿出期中考试的卷纸，“写上班级和姓名就可以答卷了。”监考老师说。于是，我就开始认真地答卷。我已经答完了，我就开始仔细地检查我答过的每一道题。当我检查到第六道大题当中的第二小题的时候，我发现这道题的得数不对呀！我连忙改正过来……中间省略地似乎才是重点哦。

我这次期中考试一定考出个好成绩！

有信心是好事。

星期五我们期中考试了，现在我十分疲惫和有点担心，时间仿佛静止了，度日如年，考好和考不好这两个词在心里打架，我紧张得就像心里有几只小兔子，能清晰地感觉到自己的心跳的节奏。

每次考试都会使我得到一个教训或一些经验，不知怎么回事，疏忽总是存在我身上，这次又犯错了，夏天的“夏”我不小心写成了复习的“复”，真的很懊恼，又丢分了，真的可惜。本来会写的，气死我了。

妈妈告诉我，考好不骄傲，考不好不气馁，以平平和和的心态应考，反而能考好，听了妈妈的这番话，我心里平静了许多。

在此我下决心，虽然疏忽不能避免，但我一定要做到尽力减少，这样才不会遗憾的流失分数。

上周我们清姜小学举办了一次，期中考试，上周星期一的夜晚，我很努力的在复习，知道复习到十点才睡觉，希望能考一个非常好的成绩。为班级争光，为妈妈的脸上争光。

第二天我起来的很早，怀着紧张的心情走向学校去，在学校里继续复习，叮铃铃，上课了，要考试了，我心里非常非常的紧张，一开始我拿的卷子只有一面，看来这第一张卷子就有问题，我拿去让老师复印，又白白费了我五分钟时间，卷子复印完给我发下来时，我更紧张了，心想，我会不会答不完，又想，答不完，答完，先试试再说，我飞快地写起了卷子，可是这次卷子有点难，我有两道题不会，心里更着急了我又想起老师的话，先把能得分的题做完，再把剩下不会的题做完，果然这一招真灵，我很快的就把卷子答完了，可突然感觉到很困，看来是昨晚没睡好，太紧张。

说着我就继续趴在桌子上睡觉了，一直睡到下课。下课我复习了复习数学，课铃一响。

我们开始数学考试，这次的数学题非常简单，我才用了20分钟就答完了，剩下的时间我没有向上次语文考试一直睡着，我把时间都用来检查了，希望考个好成绩。

下午科学考试开始了，怎么办？我中午没有学习科学，我只好认真的进入科学考试，才做了两个题，第三题就不会了，我把这题跳过了，可后面又出现很多不会的题，我只好最好把这些题放到最后写，还好科学考试的时间长，如果时间不长，我可能就答不完了。

大课间的时候我吸取了教训。开始认真的复习了英语，英语卷子发下来，我就很开心，这些题我几乎都会，太简单了，用的时间很短，只用了十分钟，我就把整个英语卷子答下来了，我检查了五遍，没有检查任何出错误，我心里很不放心，不会有题没答对吧？我又把后面的时间全用来检查，可一处错误边没检查出来，我想，是不是我状态不好呀？我想着想着就下课了。

我怀着紧张的心情回家了，心想，我一定要考个好成绩，这样妈妈来开家长会就不会低着头了，妈妈的头就会仰的高高的。

I have a good friend, we met each other when I was five years old. She is

my neighbor and the first time I saw her, she smiled at me. It was her smile

that made me feel she was a nice person to get along with. Indeed, she was a

reliable friend. When I was in trouble, she would be the first person to give me

a hand. Once I lost my key, when she heard, she tried hard to help me remember

where I lost it. I am so lucky to have her as my friend. It is hard to meet

someone who can make you feel safe and she is the one. She is the angel in my

life.

今天，天空万里无云，艳阳高照，是个难得的好天气，同学们的心里也都随之乐呵呵的，在教室里打打闹闹，好开心啊！这时班主任兼数学老师走了进来，大声地说道：同学们注意了，今天下午抽考，大家作好复习，争取取得好成绩，为我们班争光！同学们都大叫了一声啊，不会吧？便都垂下了脑袋。只见老师带着胜利的微笑走出了教室。

这个消息像晴天霹雳一样，把我们原本平静的初二年级闹得沸沸扬扬。课下同学们都在议论考试题的难易程度，都想考个好成绩。第二节课下课，我们班变的安静了许多，同学们都在努力复习，备战下午的抽考。

一上午过得可真快啊！转眼间，就到了下午考试的时间了，我们的心里也都紧张起来。铃，铃，铃，随着上课的铃声，老师也拿着卷子走了进来，我们在心里祈祷，希望题目能简单点，可等老师发下卷子来一看，我们傻眼了，上面的题好难啊！哎！没办法，硬着头皮做吧回头看看表，不会吧，还有五分钟，可还有一个题没有拿定主意呢，哎！写上算了，等我写完了，也打铃了，我长舒了一口气，总算做完了，可没等我检查检查，老师就收卷了，真不知考得怎么样。

交上卷，同学们凭着记忆对起了答案，做对的同学欢呼起来，而做错的同学也只能在一旁叹气了。可怕的抽考中。

于过去了，同学们又恢复了以往的活泼，开心的笑了。

一个月的时间匆匆而逝，月考的成绩也下来了，这次月考，考得很糟糕。对待这次月考本是自信满满的，却没到……数学：100，英语103，最让我悲哀的是语文：85。对此我要反省一下语文为什么考的那么差。

我的基础题写的还好，阅读我错的题最多，就得了几分，有的题一分也没得着。我还是觉得自我的课外知识太少。

我就应在考试前要做好准备，多多练习阅读题，把自我的思路展开，深刻理解文章含义和作者生平，要做完后再去和答案对照一下。

考试时对于一些容易的基础题要有信心和把握；然后对于一些难题，也要尽量拿分

要想语文成绩变好，就应多看一点课外书，然后提高写作水平。因为此刻语文考试写作占很多分，要想语文成绩变好，首先写作水平务必得提高，这样才能抓到分数。还就应多积累一些好词好句，和古诗，这些都是有百益而无一害的，对语文考试也都有必须的帮忙。

这次考试之所以没有考好，然后平时没有养成细致认真的习惯，考试的时候答题粗心大意、马马虎虎，导致很多题目会做却被扣分甚至没有做对。粗略看后就急于下笔，，导致阅读部分成绩不理想，得分太少

虽然我这次没考好，但我相信我要是按照上面所说的去做，下一次考试，我必须比这次考得好，争取进全班前十。

Because Thanksgiving will have this colorful society, because Thanksgiving will have sincere friendship. Because thanksgiving let us know the true meaning of life - inscription

From the babys "wah-wah" to fall to nurture him grow up, parents spent a lot of effort and sweat, weaving the number of day and night; from primary school to junior high school, and even the number of teachers for his painstaking efforts , Quietly dedicated light and heat, burning their own, lit up others.

Moreover, parents, relatives and friends to pay you not only "a drop of water", but a vast ocean. Whether you handed a cup of warm tea after your parents were tired, handed a card on their birthday, and greeted and comforted them when they were lost.

今天，又逢期中考试二年级作文的日子。我早早来到学校，认真地复习起来。过了半小时，傅老师抱着一叠试卷走进教室，紧张的考试便开始了。

我全神贯注地解答试卷。不知不觉，已经做到阅读题，这是我最头痛的题目。我皱着眉头，看完文章，开始答题。前面几小题我还能勉勉强强应付，越到后面越难。到第四小题，我一点头绪都没有，完全做不下去了。

“怎么办？时间宝贵，嘿！豁出去了！”

如此一番思想斗争之后。我半猜半蒙，手中的笔又“沙沙沙”地在卷子上移动着。

转眼间，我做到最后一小题，一看题目更傻了眼——太难啦！这时，傅老师提示的声音传来：“还剩二十八分钟，请大家抓紧时间！”

“完了完了！时间紧迫，得赶快！”我心慌意乱起来。

但转念一想：“不行！沉着冷静才能想出来！”于是，我又认真地读了一遍文章。果然，豁然开朗，我开心极了，抓起笔迅速地解答。

去掉“拦路虎”，最后是作文。我早就构思好了，胸有成竹地提起笔“唰唰唰”地写起来。写到一半时，有一句话“卡壳”了，想啊想，就在抓头挠耳之际，眼前一亮，“有了！”又继续奋笔疾书。

呼！终于写完了。正当落笔的时候，“叮铃铃！”收卷的铃声响起。“真巧！”我把考卷交给老师，这才轻松舒了一口气。

回到座位，我抽出一本课外书，给自己减减压……

“叮铃铃！”第二场考试的铃声又响起。“这么快！”我手忙脚乱地收起课外书，开始迎接英语考试。不知过了多久……

“哎！又是让人头疼的选择题！”

20**年11月4日我们学校开始进行期中考试，我怀着无比紧张与担心的心情进行了了期中考试，2011年11月5日我终于考完试了，我依然是无比的担心，伤心地走出教室。

当我知道快要进行期中考试的时候，我就非常的害怕与紧张一直跟同学说：“这次考试我不会，这门课又不会，那门课又没复过习……”这些话语，在同学的耳边一次又一次地回荡，一次又一次地重蹈覆辙，听得同学都讨厌死了。之前，我把我的时间都花在了语文默写这方面，明知自己的语文成绩还可以，还一直执迷不悟地为了应付老师每天上课的默写，把大量的时间都花在了语文默写这方面。当知道要考试了，这才清醒过来，拼命地复习，在考试的前几天才来复习，迟不迟点啊？

当考完试后，我托着沉重的身子走出教室，慢吞吞地迈着轻盈的步子，迈步在校园。抬头仰望天空是如此的阴晦，低头看看地面又是如此的湿淋淋、看看校园的树却是无精打彩，使我更加伤心与烦闷了。想到了自己做试卷的那些不该错的题目、想到了自己不会做的题目，我内心的忧愁油然而生，仿佛像知道了成绩，知道了肯定会落后、知道了结果一样，很伤心、很担心会落后，不抱任何的希望，心里也不踏实。因为以往的考试，我都没有出现过像此次这样悲伤的心情。

这次期中考试，虽然成绩还没有出来，但是我很担心、很害怕，我担心我会落后、我害怕我会因为成绩的落后而放弃了那门课的学习。“学如逆水行舟，不进则退”。再加上前段时间，我没有好好利用时间来进行学习，而是把大量的时间都花在语文默写这方面。所以，从现在起，我一定要好好地利用剩下的那段时间，来进行数学、物理的学习，把我的理科给提上来，与语文共同进退、共同进步，绝不让理科再拖我后腿。

During the summer holidays, I went to my grandmother’s home. One evening after supper, I stood on the balcony to look at the sky.

The stars in the sky were twinkling. Some were crowded, and others were separate. Then I found that the stars were not the same colour. They were white, grey, light blue and orange. It was really beautiful. At that time, the sky was like blue damask decorated by millions of bright dimonds.

Looking up at the sky, I saw the moon. It was like a naughty child, sometimes it hid in the clouds and sometimes it got out of the clouds. It seemed to play “hide and seek” with us. The stars around the moon, however, were as shy as girls, and hid themselves in the clouds.

Oh, what a beautiful sky!

The past years have seen the huge development of higher education in China and in contemporary society, it becomes a trend for universities to be ranked according to certain standards each year.Meanwhile, an increasing number of people deem it rather convenient to acquire information about quality of some universities.Searching the Internet, people can notice several editions of ranks very year.

A number of individuals favor this ranking because of its advantages.To begin with, without these ranks, it is impossible for people to make a direct comparison between different colleges.In addition, it is this ranking that enables China to build up a system of assessing higher education and to enhance its overall development.Even so, others hold the opposite view that university ranking carries some doubts.First, ranking all universities means a great amount of time and human resources; however, the quality and authority is not as satisfactory as expected.Second, what worries many experts is that some colleges may focus too much eyesight on ranking itself, ignoring the needs of students.By and large, the advantage derived the annual university ranking far outweigh the disadvantages.

An effective ranking will bring colleges motivation, arouses their enthusiasm to strive, and helps China to enhance higher education.However, it is advisable for this ranking to be scientific, practical and impartial.

明亮的窗户外飘出淡淡的梅香，看着雪中朦胧的身影，有股似曾相识的感觉……凛冽的寒冬里飘起了鹅毛般的大雪，我趴在窗户往外看，我的心里越发的不安，终于我决定还是去看看，他是不是还在那等我。我和朋友约定出门玩耍，可是，这天儿总是那麽变化无常。我走了出去，走着走着，隐约看见一个站在梅花树前。梅花的香气咄咄逼人，越来越浓。

哎呀，你怎摸这么傻呀！雪下的这么大的还来干什么呢。他抖落了身上满披着的雪花，通红的圆脸上显示出温暖。雪下的这么大的，你找不见我一定会很着急的。再说了，我们有过约定，我不会违约的。看着朋友严肃的表情，我心轰然心动。眼泪顺着我的脸颊滑了下来，流到我的嘴里，甜甜的。几朵梅花缓缓飘落，带着点儿雪，却没有任何的寒意……那一次，我流泪了，一颗晶莹的泪珠划过我的脸颊，落了下来，这里既包含了快乐，又包含着悲伤。雪越下越大，我们俩只能呆在这梅树下，几缕暖风轻轻地吹过，温暖了我也温暖了你。风儿在我们周围缓缓飘过，梅香在我们周围四处环绕，我们坐在这儿，仿佛在世外桃源般，舒服极了。会想起他当时的情景，不禁怦然心动，泪水再次顺着我的脸颊缓缓流下。梅花飘到了我的头上，我的心里仿佛流进了一股暖流。雪渐渐小了，太阳又悄悄的探出了小脑袋，微黄的阳光照进了我心中……不经历风雨怎摸能见彩虹，那一天，我认识了你。

心儿高兴的像刚抹过的镜子，透亮透亮的，似乎显示出了一道雨后在会显示的彩虹，赶走了刚才密密的乌云，让我的心情，放射出了一样的光彩。看着窗外朦胧的身影，不禁又流下了眼泪。在人生的的冬天里，有这中温情，谁还会感到寒冷呢？在漫天飞雪的时候，太阳，总是会出现的。

这次期中考试我考得很好，老师说我不仅是我们班的第一名，还是全镇三年级的第一名。听到这个消息我真的很开心。回到家里，我把这个好消息告诉了妈妈，妈妈也表扬了我。

这次考试我想我能考得这么好，跟我们老师的辛勤教育是分不开的。谢老师是我们的班主任兼数学老师。她是个很漂亮但是又很严厉的女老师。我们班同学对她都是又爱又怕。我们很爱谢老师是因为谢老师也很爱我们。她给我们讲课，教我们道理，每天围着我们一起转。有一次谢老师的脚受伤了她还是一样的给我们上课。但是她又对我们很严厉，所以我们都很怕她。我们的语文老师是刘老师。她也是个很漂亮但是很严厉的老师。同学们也有点怕她。我想对老师说声：老师，您们辛苦了！

谢老师说“考得好的同学不要骄傲，要再接再厉，争取考得更好。考得不好的同学不要灰心，要继续加油，争取考得更好。”

刘老师说“学习如逆水行舟，不进则退。”这句话的意思就是说学习像逆流而进的小船，不努力向前进就只能倒退了。刘老师还说她希望我们每天进步一点一点，一天比一天有进步。她也要我们互相帮助，她让我去帮助胡幼。

期中考试已经过去了。虽然我考得很好，但是我一定不能骄傲，还要继续努力，争取下次考得更好。我也要好好的帮助同学，让他们下次也考出好成绩。

考试，是人在求知的路途中最不可避免的一个过程，它考验了我们的学习效果，同时也检验了我们学习的态度，是我们人生中不可或缺的一部分。

在严冷的十一月，我们迎来了学期最重要的考试——期中考试。在数学考场上，有120分钟的时间来考试，本以为时间很富裕，但没想到，这次的试卷比往常的难很多，时间不充裕，试卷刚刚写完，还没来得及检查一遍，便收卷了。在英语考场上也是这样。

考完试之后，我想：完了，题目有些还没写完，肯定会考得很差。果真，星期四、星期五成绩就出来了，虽然不知道班级排名，但我已经可以估出来了。这次的成绩都很低，加起来不到300分，这是我有史以来考的最差的一次。虽然不是最后一名，但是，我不能气馁，因为我们要向远处看，而不是往低处看，这样你的成绩就会下降。

“长风破浪会有时，直挂云帆济沧海”我会以这次考试为契机，仔细分析自己得失的原因，查漏补缺，努力向前。
