不知不觉，我们已过了初中生活的一半了，只剩下一个半的学期，马上我们就要离开培育了我们三年的校园和可敬的老师们了。一路走来，既有苦也有乐，而且我们还能在苦中作乐。 Unconsciously, we have passed half of life in junior high school, only one and a half semesters are left, and we will leave our three years of campus and the campus andThe respectable teachers.Along the way, we have both suffering and joy, and we can also make fun in suffering.

说到苦，我倒不觉得学习和作业是如此多而感到烦恼，因为学习本身就是我们生活在世界上的必经之路每一个人都要度过，因为学习负担重，压得我们喘不过气来只能怪自己没完成任务，可见在作业量方面，我们没资格说“苦”。

因为能通过在做作业上，知道自己有什么作业知道和不知道做的，不知道的我们可以到老师那咨询，会做的说明了，自己是有实力的。倒是在学习总是上有一些烦恼，例如一道数学题，如果我们绞尽脑汁也想不出解法来，那么有人会说“唉!算了吧!

我见到这种题就苦恼，真倒霉。我想这种心态是我们不应具有的。因为我们要在不知道的题目中学习。在不久之后，我们将通过中考踏入高中的大门。那么就有多数人为考不起高中或特重点高中而苦闷。处在初中阶段的学生比如我，因为一次竞选落选而整整苦闷了好几天。

唉!初中生活特别是初三最苦，好像一天二十四小时还不够我们支配，一周七天还不够我们学习;但是我们也伴着这些苦在逐渐长大，逐渐成熟，可见“苦“也有利于我们在实际生活中的锻炼。我喜欢独立思考，然后再与同学甚至是老师辩论，我觉得，这对我来说可以是一种莫大的乐趣，是啊!

同学之间互相交往思想是多么有趣啊!多么有益啊!还有一处乐趣：化学课生动活泼，老师是亲切和蔼，幽默，灰谐，我们都愿意上他的课，在他的课上，我们可以笑得很开朗却又不担误课程，上他的课，我的感觉棒极了。也正因为这样让我的学习有所进步。

初中的生活是多姿多彩的，是无与伦比的。我爱初中生活。初中教育了我的一切。

My holidays This summer, I was very happy. Although I didnt go out to travel. But my friends and me to a nursing home to help old people.In a nursing home, we introduce myself after, began to work for the old people. First of all, we first points groups. Some go to sweeping the floor, others to help old people back on, some with old people, and my sorrows and other friends to help the old man sun wash the quilt.We started, we use the washing powder on the old people on the quilt, rub with the brush and rub, very tired. I understand the mothers hard work. Then, we will bask in the quilt.We stayed for a nursing home in the afternoon, and the old man say good-bye, I have decided to help your parents do some housework more in the future.

我的假期生活这个暑假,我非常开心.虽然我没有出去旅游。但是我和朋友们到养老院去帮助老人们。到了养老院,我们自我介绍了后,就开始为老人们做事了。首先,我们先分了组。有的去扫地,有的去帮老人们捶背,有的陪老人们解闷,而我和其他的朋友帮老人晒洗被子。我们开始了,我们用洗衣粉洒在老人们的被子上,用刷子搓了又搓,很累。我体会到了妈妈的辛苦。接着,我们就晒被子了。我们在养老院待了一个下午,和老人道别后,我决定以后多帮父母做家务。

I like my school .My school life is nice,too.Now,I will tell you something about my school life.I usually qo to school at seven o"clock.We have eight lessons every day.At about five o"clock,Igo homeand do my homework.My school life isn"tvery intreseting,but it is very useful for me.

在炎炎盛夏，我们小学生最期待的暑假来临了，我们一家趁着天气大好，打算一起出去玩。这时，妈妈灵机一动，提议说：“去看看开平的碉楼吧!那里很有名的。”经过我们的一致同意后，我们一家人浩浩荡荡的踏上了前往开平的旅途了。

经过大约三四个小时的车程后，旅游大巴终于把我们一家送到了一个很大很高的牌坊前面，那个牌坊上立着赫然几个大字——三门里。我一头雾水，非常不解：“这里为什么要叫三门里呢?难道有什么特殊的含义吗?”一旁的妈妈也是二丈和尚——摸不着头脑：“我也不知道，也许是这里的人喜欢吧!”我们讨论许久，都讨论不出一个所以然来，我也只好就此作罢。

继续往前走，就看见了一片片嫩绿色的稻田，田里的庄稼接受了雨露的灌溉，变得更加绿意盎然，生机勃勃了。看完了这边的景色，我又把头一扭，看见了在一棵松杉葱郁的参天大树下，一些村民们正坐在石凳上高声谈笑，好不畅快。他们爽朗的笑声，让络绎不绝的路人都心生羡慕。

走了好一阵子，终于看到了一座高大雄伟的开平碉楼——迎龙楼。它建于明嘉靖年间，坐西北向东南。也许是因为随着时代的变迁的缘故，迎龙楼外面原本光鲜亮丽的油漆差不多都掉光了，只剩下了土黄色的砖头，但是迎龙楼的构造还依稀可见。我抚摸着迎龙楼上的炮口、枪口。好像看见了当年血肉横飞的战争场面：一大群武装到牙齿的侵略军手持机关枪，戴着防弹头盔，拉着一辆辆大炮，来到迎龙楼前，准备占领这里。坚强不屈的战士们手持小米加步枪，藏在迎龙楼里，异常勇猛地向敌人进攻。这场战争持续了大约十多个小时，侵略军最终不敌战士们，败下阵来，落荒而逃。迎龙楼被打的全身是洞，遍体鳞伤，但它却大大减少战士们的伤亡。可以说，是迎龙楼保护了他们，帮助了他们，不，是帮助了这个村子里的所有人。我们要感谢迎龙楼的存在，更要感谢建设迎龙楼的先辈们，如果没有他们，也许就没有我们今天幸福安逸的生活了。

迎龙楼，是多么伟大啊!不，所有的开平碉楼都很伟大。我们应该怀着崇敬的心理去看待它们。

Too many cars have created a lot of serious problems in our world. Besides congestion， accidents and fast fuel consumption， cars are responsible for a good part of air pollution in big cities. All the time， they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful， causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai， some of the public buses begin to run on natural gas， which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough， most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole， the elimination of air pollution needs the collective efforts from the government， the public and the environmentalists.

My Opinion on Cheating in Examinations

It is known to us all that some students cheat in examinations at school．

As students，we often take examinations at school，but sometimes we have too many examinations which are too difficult for us．On the other hand，some of us are lazy and dont work hard at their lessons．So when taking examinations，they sometimes cheat in order to get better results to please their parents and teachers．

In my opinion，it is wrong to cheat in examinations because it breaks the rules of schools．We students should be honest and try to get good results by studying hard instead of cheating in examinations．Whats more，we should improve our study methods and get well prepared for examinations．

It was the first day of our summer holiday. All of us were very happy. Why? Because we have one month to do things we love to do. We are free. Although we have some homework. But we can finish them in several days. And the rest time we can make good use of. My god! We have been very tired after hard studying. In winter holidays, I want to have full sleep and eat good food in order to replenish myself. Last but not the least; I will have a good rest.

This July, I graduated from primary school. I was enrolled to a good middle school. Therefore, I had a happy and leisure summer holiday. In the middle of July, I attended to a summer camp. It’s about English. There were twenty five students in the camp. We all like English very much. Together, we studied and played. There were many activities, team work or single performance. We tried our best to put ourselves into this big family. Most of the time, we talked to each other in English. If we really don’t know how to express in English, we could ask for help. Our teachers were so great that they could help us a lot. They were so active that make us acted as they did. I am happy to attend this activity.

写暑假生活的英语日记【篇3】

以前的我，是那么的向往高中生活。为此我还看过许多的青春剧，背景都是关于高中生活和高考的。令我印象深刻的应该就是《青春派》了吧！当时的我，不懂男主为何会因为高考落榜而难过，不知道他重来一次的勇气，只觉得落榜就落榜呗，复读就复读呗。不在这当中，当然感受不到主人公所处的环境的痛苦了！

以前的我，认为高中是美好的，是我的这一段青春当中最美好的。但当我身临其中，这里的生活简直就是繁忙的。日复一日，年复一年。每天像一台机器，不停的按时运转。有时候的我，真的很迷茫，我不知道我的未来会是怎样的。每天都累成狗。

如果说初中是单纯的，那么高中就是懵懂的。在这样的年纪里，我们一直在效仿者大人的生活。正所谓“看到了美好而努力追赶美好，这就是向往的力量，但是人间总不会总是充满美好的，有阳光的地方必有阴影，和谐社会也经常冒出不和谐的声音。更何况是高中的校园呢？拥有不能容忍他人遗世独立，抱着“我既入地狱，就要世间无天堂”的偏执将人性的自私、狭隘、恶毒展露无遗。

When weekends come, everyone is happy about that, because they don’t need

to work and can do what they want. Some people will choose to stay at home and

watch TV all the time, some will choose to go shopping, while for me, I’d like

to go out. I want to see the different things and refresh my mood. I always make

some plans for my weekend.

Sometimes I will ask my friends to go to watch the movies or we go out for

the gourmet. I like to see movie so much, watching the movie is like reading a

book, my mind will gain things and I will feel satisfied. Eating the delicious

food is the things I will do mostly, I like to find the new food, and ask my

friends to enjoy it. We will talk happily while eating the delicious food.

I am busy from Monday to Friday, I don’t have much time to take exercise,

so I will go hiking with my friends on weekend. We will bring little food and

take a backpack, heading to the park or beautiful mountain. We can enjoy the

beautiful scenery, at the same time, to exercise our bodies.

My weekend is full of plans and I enjoy them all.

When the summer holiday comes, I will be very happy, because my family and I will go to travel. I like travel so much, I can not only see the beautiful scenery, but also can spend the time with my parents. I feel so easy and don’t have to study, I just play and enjoy my moment. This is my most happy days.

当暑假来临时,我会非常高兴,因为我和我的家人要去旅游。我喜欢旅游,不仅可以看到美丽的风景,还可以花时间与我的父母在一起。我觉得很放松,不需要学习,我只玩和享受的时刻。这是我最快乐的日子。

Today, I got up at8:00 at usual. And I have a busy day. In the morning, I studied for two hours. Andthen my father told me to visit my uncle with him. We took something to him andhad lunch at his home. We went home at 14:00. When we got home, my mother was cleaning our home, so my father and I helped her. I cleaned my room. It was alittle dirty. After that, we went to the supermarket. I bought some snacks. I wastired today.

今天，我像往常一样八点起床，并且度过了忙碌的一天，早上，我学习了两小时。然后爸爸叫我和他一起去看叔叔。我们带了一些东西给他并在那吃了午饭。两点我们就回家了，当我们回到家的时候妈妈正在打扫屋子因此我和爸爸就帮忙。我打扫我的房间，房间有点脏。打扫完屋子后我们去了超市，我买了一些零食。我今天很累。

n my understanding, if we refer to an ideal college life as a formal western dinner, then a high GPA, that is, Grade Point Average, should be the main course, while an active part in activities, together with associations, means the appetizer. Some romances, of course, play the role as desserts. They are the 3 key elements for an ideal college life.

Those, however, are not what college life is all about. As we all know, college is wildly different from middle school. It connects not only adolescence to adulthood, but also the ivory tower to the real society. Therefore, the ideal college life is that I become matured both physically and mentally, and that I obtain qualified academic knowledge and get well prepared for society at the same time.

Under this circumstance, I never expect my college life to be too ideal, or you can call it too perfect. It is not realistic to make all things on my own way, with everyone liking me, winning the first prize all the time, and so on. Of course, I’d like to lead a carefree life. However, this does little good to my future. What really helps is hardships like failure, betrayal, and unjust treatment. Only after experiencing those can I know what society is like, and what life is like.

To conclude my speech, I wanna say, some positive experiences are surely part of the ideal college life. But, I should not forget about the negative sides. They are not less necessary.

Which place we look forward to university, the number of students of senior three. University life, every high school students dream of want to experience. At least I was at that time. But, to be honest, the university for me at that time is a kind of imagination of good, but how, I want to now I didnt have a certain understanding to him.

In college, we wont have the teacher make the teachings and anticorrosive tireless explains. Wont have too many exercises and tests every day; Dont every day in order to score, ranking and anxious, upset... In the experience of college life this month, there is such a thing let me more impressive: in the first class of the university, there are two girl for a few minutes late, according to the habit of playing before the report into the classroom. But then the teacher said: "in the university, if you be late for class or something you want to leave early, you dont have to report, just quietly in and out from the back door, it is good to do not affect you..." After this, I also met in high school even dare not even think about other things. Can at any time in and out of the dormitory and the school, for example, because of the need to accomplish something to skip class, etc.

So, I concluded that university, is a completely on the process of consciously. If high school we or a chick, so we can say of university has been growing up, away from the shelter of parents, away from the teachers supervision, the rest of the only one to do the master of himself.

So, now we are going to manage themselves, their planning their beautiful university life, and ensure that the future can smile about their college life.

At the university of the second characteristic is to have more time and space, the university will have a class from 5 points to the dormitory in the morning until 10 PM back rest; Also wont because like to see a dream of red mansions but afraid to be the teacher found and hide things, and more importantly, there are all kinds of activities in the university for you to participate in and experience, and these are considered in high school is a waste of time. In fact, we can learn much knowledge from these things - and without the knowledge of the textbook, learned a lot of experience or lessons, learn from the university of rich and colorful...

So, I think, is more important than knowledge ability, and ability to training needs a process, the university is such a good process.

大学，多少高三学子向往的地方。大学生活，每一个高中生都梦寐以求的的想去体验一番。至少当时的我是这样。但是，说句实话，大学对那时的我来说只是一种想象中的美好，但究竟如何，我想现在的我才对他有一定的了解。

在大学，不会再有老师苦口婆心的教诲和防腐不知疲倦的讲解;不会有每天做不完的习题和试卷;也不会天天为了分数、名次而焦急、苦恼……在体验大学生活的这一个月中，有这样一件事让我印象比较深刻：在大学的第一堂课上，有两个女生迟到了几分钟，按照以前的习惯打报告进教室。但后来老师说：“在大学中，如果你上课迟到或者有事想要早退的话，你不用打报告，只需悄悄地从后门出入，不要影响大家就好……”在这以后，我也遇到过其他在高中甚至想都不敢想的事情。比如可以随时出入宿舍和校门，因需要完成某事要逃课等。

所以，我总结出：大学，是一个完全靠自觉的过程。如果高中的我们还是一只雏鸟，那么大学的我们可以说已经长大，远离了父母的庇护，远离了老师的督促，剩下的只有自己做自己的主人。

所以，现在的我们要自己管好自己，自己规划自己美好的大学生活，并自己保证今后能够笑着谈起自己的大学生活。

大学的第二个特点就是有更多的时间和空间，大学中绝不会有从早上5点出宿舍上课直到晚上10点才回去休息的情况;也不会因为喜欢看《红楼梦》但怕被老师发现而东躲西藏的事情，更重要的是，在大学里有各种各样的活动等着你去参加和体验，而这些在高中都被视为纯属浪费时间的事情。其实，从这些事情中我们也能学到许多知识——课本里并没有的知识，学到许多经验或是教训，学到大学的丰富多彩……

所以，我认为，比知识更重要的是能力，而能力地培养需要一个过程，大学则是这样一个很好的过程。

Today, my brother went to school in Jinan and my father brought me up. Dad wanted me to feel the life of the University. We came to Shandong Normal University, and that was the fathers alma mater. The entrance is very blocked, because today is the date of new arrival, so there are so many vehicles that we cant go in very easily. Once we enter the mountains, we have many big sisters and big brothers, holding the brands of their colleges to welcome the arrival of new students. The first picture was the statue of Chairman Mao. An air of teaching building, a clean lawn. There are tall laboratory buildings, libraries, and hundreds of thousands of books, books, books, books, books, books, books, and books. It is a sea of knowledge. My father said so, I want to go in and see, but dad said that there must be a card to go in to see, but I had to imagine in it.

Every time I go to a place, I will ask my father what it is for. My father introduced me like a tour guide, and I listened carefully. Dad told me that he was in college at that time. I think college life is really meaningful. We came to the dormitory imperceptibly brother, I look dumbfounded, the corridor inside the dark, than I imagined. My father was busy explaining to me that I knew the house was a few decades old, so it was so old. Let me have a bad feeling about college life. I said, "I cant test this school in the future, and the environment is too bad." But I listen to my father that the learning atmosphere of this school is still very strong, everyone can learn. I want to grow up quickly and get into the dream college life earlier.

This Sunday, my father decided to take me fishing. I heard the news I was so excited, because I had never fished.

We drove to a nearby pond, fishing has been prepared to put my father took out material - fishing rod and earthworm feeding the fish. First of all, we first worm on a hook string, then hooks thrown too far. We just sit down, I saw the float sank, father nervously exclaimed: "promise, fast closing fishing rod." Ill go back, my father to help pull the fishing line. I saw caught a fish, they scramble to catch it.

Soon we caught a few fish, but soon the fish is not hooked. I started getting impatient, she kept pulling hook up to look at. Dad said to me:. "Fishing most exquisite patience, youll scare the fish pulled constantly," I patiently wait, and sure enough there are a fish took the bait.

This weekend Im so happy, not only learned to fish, but also recognize the truth: Only people who have the patience to get good grades.

今天，妈妈拿回来一箱水果。

水果盒好漂亮啊，里面有各种各样的水果。我奇怪的是那里面有一个像土豆一样的毛绒绒的水果。我问妈妈：“这是什么东西?”妈妈说：“是猕猴桃。”我迫不及待地说：“我要吃、我要吃!”妈妈把皮削开，果肉是绿的，再把它切成两半，一看，咦，里面还有许多像芝麻一样的小黑点呢!我吃进去尝了尝，哈，酸酸甜甜的，真好吃!妈妈说，猕猴桃还有丰富的维生素呢。

看来，每种水果都有自己的味道，而且都有自己的特色，不要小瞧它们哦!

数学是一个抽象的概念，它就是一种学术的研究。它看似没有什么实际性的作用，但是隐隐中却能应用在日常生活中的方方面面。

一方面，数学经常会让人感到自己很笨，有时候甚至会让自己很生气，很恼火。因为多数人都感觉它很枯燥难懂，并且很难寻找对数学的兴趣。而另一方面，数学又变成一个有趣的东西，它甚至成为了我们日常日常生活中的一部分。

我常常有这样一个问题：为什么数学如此枯燥，却仍是有那么多的同学如此热爱它？带着这个问题，我找了一些热爱数学的同学。在他们眼里，数学是这样的：有趣，它将我们日常生活中的很多东西数字化，通过逻辑推理，给出答案，让我们的日常生活变得更加简单，方便。同时，数学的严谨同样也吸引了他们。因为，他们认为在数学的世界里，黑就是黑，白就是白，没有处于黑与白之间的灰色地带。数学淳朴，可爱，单纯，它绝不含一丝杂质。

角度不同，看法便有不同。有一千个读者就有一千个哈姆雷特。事实上，数学本身就很有趣，它能成为我们日常日常生活中的一部分。

我曾在初中时学过一些简单的一元一次函数，而就在最近我又对一元一次函数进行了更深一步的研究认真学习。

在我认真学习一元一次函数的过程中，我渐渐发现，一元一次函数在我们的日常日常生活中应用十分广泛。如当我们在社会上进行消费活动时候，若果其中涉及到变量的线性依存关系，我们就可以通过利用一元一次函数来解决问题。

社会日常生活之中，当我们出外旅游选择酒店下榻，当我们去步行街或者超市购物时，细心的人都会留意到一点：商家为了达到宣传、促销等其他不为人知的目的时，通常都会为作为消费者的我们提供两种或两种以上的付款方式或优惠方法。通俗来说，就是为我们提供套餐、打折优惠之类的服务。

恰恰每当这时，很多人都仅仅看到了宣传单上诱人的“省钱”方法，却忽略了如何取舍才是最为关键。在这时我们就真的应该三思而后行，发掘自己头脑中的数学知识，做出明智的选择。俗话说得好：“买的没有卖的精。”我们绝对不可以随意听信销售人员“甜蜜”的话语，也决不可盲目跟从，以免上了商家设的局，吃了大亏。

因为我是学校茶文化社的社员，所以每次茶文化社的出外活动我大多都会跟着一块出去。一次，是社团里的师兄师姐们出外比赛，我便跟随着他们一同外出。比赛的场地是在一个名为“茶都”的地方。

趁着空闲的时间，我便拉着一位好朋友一起在那四周围瞎逛。忽然，我们的眼球被一块醒目的告示牌吸引住了。那块告示牌上写着：购买盖碗、品茗杯有优惠。优惠方式也有两种，一种是买一送一，既是买一个盖碗送一只品茗杯；另一种则是打九折。但是最让我感到诧异的是要想享受这两种之一的优惠方式还有一个前提条件：购买盖碗3个以上（盖碗20元一个，茶杯5元一个）。当时我就愣住了，这两种方法有区别吗？应该是有区别的，但是两者相比到底哪一种更便宜呢？带着这个问题，我便马上把这个有趣的数学现象用手机拍了下来。

回到家后，为了解开我心中的这个结，我翻阅了初中还有现在的数学书。那就像是灵机一动，我联想到了函数关系式，然后就间接地想到了我最近所学的一元一次函数。

我首先设某人买品茗杯x只，付款y元，当然这其中还有一个隐含条件就是（x>3且x∈N）。则：

第一种方式付款便是y1=4*20+(x—4)*5=5x+60

用第二钟方式付款便是y2=(20*4+5x)*0.9=4.5x+72

接着就来比较y1和y2的相对大小：

设c=y1—y2=5x+60—(4.5x+72)=0.5x—12

然后就要展开讨论：

当c大于0时，0.5x—12大于0，即x大于24

当c等于0时，x等于24

当c小于0时，x小于24

综上所述，当所购买的品茗杯多于24只的时候，第二种方法更优惠；刚好购买24只的时候，两种方法价格相等；当购买的杯子数量在4到23之间的时候，第一种方法更优惠。

由此可见，用一元一次函数来看待购物，不但节省了钱财，还锻炼了我的数学思维，真可谓是一举两得啊！

我们作为新世纪的中学生，我们同时也是即将踏入社会的学生，我们认真学习数学不能仅仅只停留在课堂上，书本上，更多的是学会在日常生活中发现数学，并尝试着利用数学去解决问题。

告别了无忧无虑的童年，逝去了天真烂漫小学时光，我跨进了初中校园的门槛，开始了我五彩缤纷的初一生活。我刚进入初中的第一天，我心里非常兴奋，因为我看到了自己六年的劳动成果。记得在小学我是多么渴望能尽快的进入初中，今天我终于实现了我的梦想。

当我走进一个新的班级时，看到一位位新同学，他们的欢声笑语，使我想起了那活波可爱的小学同学。看到每位新老师，他们在黑板上写的每一个字，让我想起了我那慈祥的启蒙老师。我看到了这宽阔的教室，使我想起那狭窄的小学课堂，我的初一生活是“酸”的。

当我在座位上闷闷不乐时，同学们都在一旁问长问短。当我需要帮助事，他们都身伸出援助之手来帮助我，因为我在小学并没有在学校住宿过，还不熟悉。每次我没有水用，他们都不?思索的去帮我抬水，一刹那我感受到了我的初一生活是“甜”的。

在段考的时候我没有考好，看到那人人讨厌的符号“叉”时，听到老师批评的话语，回到家父母就急着问我的分数。我无可奈何，只好硬着头皮把成绩告诉父母，这时我感到我的初一生活是”辣”的.

期考快要来临，作业;试卷逐渐增多,光是作业就压得我咽不过气来一张张白白的试卷又来了,在学校写、在家里写;课上写、课下写;白天写、晚上写……一整天都没有闲的时候，这是我感到我的初一生活是”苦’’的.

我的初一生活真有趣,参杂着“酸.甜苦辣”,这些只是我的初一生活的一些插曲,这个集体给我带来了无比的欢乐,使我的生活更充实动人愉快……

千言万语,只有一句话:我爱我的初一生活!
