大学生英语日记大全800字【实用20篇】

Today the weather was terrible，so I had to stay at home.

In the afternoon，I finished some homework,then I thought that maybe today

was very boring。I stared to surf the Internet ,and I found the movie 《Ghost

Rider》which was directed by Mark Steven Johnson by accident and then I began to

watch it. The movie told us that a lover of motorcycle called Johnny signed an

agreement with a demon in order to save relatives‘’ lives .However,he lost his

spirit and had to work for the demon.Then He used his spell to fight with evil .

The movie was so exciting that I coulnt be calm 。I would never forget this

movie.

今天天气很糟糕，所以我只好呆在家里。下午，我完成我的一些作业，然后我想今天一定会很无聊吧。我便开始上网，偶然地发现了一部由马克·斯蒂文·约翰逊主导的电影《鬼面骑士》，我便开始观看。这部影片讲诉了一个名叫强尼的摩托车爱好者为了挽救他亲人的性命与恶魔签署了一份契约。但是，他因此而失去了灵魂，被迫给恶魔工作。他用他的魔力与邪恶作斗争。这部影片是如此的振奋人心以至于我不能平息我的内心。我永远都不会忘记这部电影。

今天心情其实蛮沉重的，排里的人被拆分了很多，目送着他们一个个离开，心中很不是滋味，教官也是万分不舍。我们即使想挽留，但是，他们却可以因此可以更加强大，也可以让九排的荣誉更辉煌，我们又怎么能挽留他们呢?

早上，被挑选了十一个战友进入方阵，其中还有一个当了女排头兵，这可是莫大的光荣!下午，又有四个战友被排选进了花圈方阵，但是他们逃离回来了，那刻，我看见她们眼睛都红了。怀着复杂的心情，百感交集着训练，连教官也没有了心思，谈气惋惜。于是，整天下来都不在状态上，连跑步训练也只学了半小时。幸好，当那四位战友回来时，排里士气大振了许多。

排里少了人，但同时也来了十七排的新战友，教官未我们取名为“179加强排”，当我们调侃说“无敌排”时，教官终于露出了微笑，松了眉头说：“不能太高调啦!”我们也对视大笑起来。69个人，多了生机，少了伤感。

晚上下着蒙蒙细雨，原来学习擒敌拳的计划被打乱，我们转移阵地到架空层，展开了179排大联谊，比拼唱功，很不幸的是，我们连续输了三次，但惩罚却是双方的，很有趣，虽然教官一直在旁边静静地看着，但是，我认为，他应该不知道我们唱的绝大多数歌曲。其中有一幕最忍俊不禁，就是十七排的副排长做自我介绍时，竟说出：“大家好，我是17排的排长。”此刻，我们都狂呼：“你夺了教官的位置!教官快惩罚他!”教官淡定地站起，做了一个“嘘”的动作，又安然向他对视，我们都快笑出眼泪了。

179排，并不是所谓的“酱油”排，因为我们有“挑剔”的教官在，肯定可有变得更强大!而且很多优秀人才“誓死”跟随教官留在本排，可见我们教官人格魅力之大。

是的，今天经历了别离，但是我相信他们的心还在我们大本排，重逢是必然的事;今天也认识了一帮战友，坦诚相对着。或许，军训也在教我们选择，是去?还是留?选择总是痛苦的，但选择过后，我们必须坚定地走下去，因为这是我们的选择，跟随着自己的心走。“塞翁失马，焉知非福，”凡事皆有两面，但是我坚信着，我们的心一直在一起，未被分开过!这不仅是团结，更是信任的力量!

Today is Friday. It is my thirteenth birthday. I got up very early in the

morning and put on my new clothes happily. My parents bought me the new clothes

as my birthday presents. I went to school earlier than before.I invited many of

I havent write diaries for a period of time. I am now writing this just want to remember one thing. My study has fallen behind a lot this term. I can keep my score in the top ten in the whole school ranking before. But this term I fall behind. I nearly draw back to fifty. I know the reason is because I am too arrogant. I think I can be the best without studying hard. So I usually not pay too much attention on my study. When I find myself lag behind, I comfort myself it is accident. I have learnt a serious lesson this time. So, I want to write it down to warn myself.

我已经有一段时间没有写日记了。我现在写这篇日记只是想要记住一件事。这个学期我的学业落后了很多。我成绩之前可以保持在全校前十名。但这个学期我后退了。我差点就退到了五十名了。我知道原因是我太自大了。我觉得我不努力学习也可以保持最好。所以我一般都不怎么在意我的学习。当我发现自己落后时，我安慰自己只是意外。这一次我吸取了深刻的教训。所以，我想把它写下来以此警示着我。

两年以前，我很喜欢吃泡面，泡面闻起来很香，因为有美味的调料在里面。当我妈妈不在家的时候，我会买泡面吃，随着时间的流逝，我发现我的皮肤变得不好，我也不怎么喜欢吃米饭。我感到糟糕极了，我的妈妈告诉我我不应该吃那么多的泡面，这些没有营养，也让我胃口不好。我意识到了我的问题，开始不吃泡面，我的胃口变好了，也有食欲吃米饭。泡面是垃圾食品，我们最好少吃。

9月4号和5号学校迎新生，学校内一片热闹场景，新来的学弟学妹们带着对未来的憧憬走进大学，送行的家长怀揣着不舍和对孩子们的期望，离开了孩子们即将生活的地方。新的地方，新的环境，新的同学，一切都是新的。看到新生们兴奋快乐的眼眸，不由想起去年懵懂的我们。青涩的孩童在走向大学的那一刻就意味着要独立，要自主，要成熟。还记得刚看到室友的那几天，说实话，我有点紧张。不知自己是否可以和大家和谐相处，不知自己是否可以离开父母的羽翼，茁壮成长。一点点的熟识，一点点的交往，发现大家各有各特点，又天真可爱的妞，有泼辣犀利的湖南妹子，有新疆单纯漂亮爱打扮的美女，有山西细腻勤快的小屁孩，还有宁夏爱跳舞的包子。我们间有吵闹、有摩擦、也有快乐和美好。

还记得迎新年(元旦)的时候，我们静静聆听着对面楼研究生哥哥们的高声呐喊，之后我们在宿舍happpy，后半夜三点依旧无眠;还记得，某个人的食物还未打开时，我们已经在一旁准备好了筷子和叉子，蓄势待发，一旦打开，“饿狼般蜂拥而至”，欢声笑语中，留下一片狼藉;还记得某人生日的时候，我们畅游大雁塔广场，在音乐喷泉前摆pose合影，在灯笼树下秀逗，在纪念品摊子前踯躅徘徊…这都是属于我们的美好片段。

看到新生们军训，他们着军装英姿飒爽，尽显蓬勃朝气。看到他们早出晚归的情景，有一丝庆幸，我们已经结束了那般艰苦的训练。不用在烈日下站军姿，不用冒着雨练正步，也不用在田径场上忍受蚊虫的叮咬。但是，我还是很羡慕他们的，因为他们依旧可以享受军训的乐趣，唱军歌、交朋友、拉歌赛…还记得我当时最喜欢的军歌就是那首《军中绿花》，柔美中带着坚强，平缓中尽显风骨。在漆黑的夜晚中，唱起这首歌给人一种空灵、飘逸的感觉，显示出女性美。

……

我们的故事还有很多，我们的友谊继续巩固，我们的天空还要继续延伸。总而言之，我的生活充满乐趣，我热爱我的大学生活。

眼睛微睁，看着窗外朦胧的天，一景的陌生，而又如此熟悉，看看时钟，才六点二十多，记得每次放假我总要睡到日上三杆的时候!可今天，在家，自己的床上，却不同往日的醒得这么早，是失眠吗?

不过，我想应该不是!六点二十，多么熟悉的时间啊!军训的这十多天来，我们都是这个特定的时间起床的!或许，这个时间醒来已成了我生活的一种习惯，或许，这个时间一种已经和我产生一种默契!

然而，窗外朦胧的天在强烈的召唤我，我下意识的在心中说到“该出早操啦!”就在我翻身跃起的瞬间，我才恍然--军训已经在昨天结束了……

是的，军训在昨天结束了!军训在昨天已经结束了!心头一种不可名状的翻来覆去的痛!

不觉的时间已经到了六点半!也就是出早操的时间，可是，没有了早操的铃声，没有看到几百个穿着军训服的同学慌慌张张急急忙忙的跑到操场集合，没有看到两行排得整整齐齐步伐一致的士兵向我们跑来，也没有听到如雷贯耳的声声番号，更没有听到…更没有听到教官铿襁有力却又带着几分亲切的嗓音!这样安静的早晨，让我很不习惯，也好难去习惯，比当初适应军训还难一百倍，一千倍……

是啊，有的人走了，他们留下的深刻，是我们一辈子也忘不了的，那些让我们放在心里的珍贵，已成我们生活的一种习惯，一种依赖!

不觉的发现自己的眼眶微微的有些热了，这种感觉似曾相识，近在眼前，浮在脑海，厉厉在目……

昨天我们在台上最后一次听教官指令表演军体拳，在整个表演过程我始终咬紧着牙关，好像在硬撑什么，眼眶一直都是热热的，直到教官下达最后一声指令，我用尽全身力气和早已莎哑的声音大声的吼出了最后一声口号，我们的表演很成功，可是，都是经过好多次的彩排，才会如此完美，像紧张一样，练习多了，对表演也就麻木了，一点恐惧也没有了，可是，这样的离别，我们从未练习，也没彩排，也没有谁曾告诉我们应该怎样祛微笑面对，叫我如何麻木………

春天来了，天气不冷不热，十分暖和。万物开始复苏。今天早上，我和朋友刘欣一起去中山公园游玩。

当我们进入公园，鲜花迎面扑来。蜜蜂和蝴蝶在花丛中飞舞。池塘里的鱼儿自由自在地游来游去。岸边的柳树住在发芽。亭子里，老人在下棋。看，一些孩子正在湖边做游戏。树叶儿变绿了，花儿竞相开放。树上有些鸟儿，它们在欢快地唱歌。

公园的一切都在告诉我们春天已经来临。多么美丽的景象啊！我们玩得真开心！

感恩节就要来了，在十一月的第四个星期天。感恩节在西方很流行，在那天，人们烤火鸡来吃。这个节日是为了纪念印第安人们的友好。很久以前，一些清教徒乘着“五月花”号船去美国寻求自由，但是他们遭遇饥饿和疾病，印第安人们帮助了他们，提供他们食物并治疗他们。清教徒播种，希望有好的丰收，最后，他们得到了好的丰收，很感激上帝和印第安人，所以他们决定定一个日子来记住这些并表示感谢。

英文日记和汉语日记一样，是用来记叙一天中所发生的有意义的事情或对将来的打算等。以下是小编整理的英语日记写作的格式，欢迎阅读！

日记可分为记事、议论、描写及抒情等。记事型是用英语记述当天自己生活学习中发生的事情。议论型是对生活中的某一事情或情况现象谈自己的看法，发表议论。描写型或抒情型，则是对某人物事物的特征做细致的描述，或针对某事物抒发自己的感情。

1、格式：

一般是在左上角记上当天日期，星期，时间的排列法与书信一致，星期写在日期之后；右上角写上当天的天气情况，表示天气情况的词一般是形容词，如：fine（晴朗的），cold（寒冷的），snowy（下雪），sunny（阳光充足的），rainy（下雨的），cloudy（阴天的）等。日记的小标题写在下一行，也可省略不写。

2、时态：

写日记的时间一般是在下午、晚上，有时也可以在第二天补写，因此，日记中所记述的事情通常发生在过去，常用一般过去时；但当记述天气、描写景色或展望未来时，可以用一般现在时或一般将来时。

写法大致和写汉语日记相同，都是在正文之前有日期、星期几及当天的天气情况。注意内容表达要清楚连贯、准确。

扩展阅读：

日期格式用月日年（美式）或日月年（英式）都可以

1. 年、月、日都写时，通常以月、日、年为顺序，月份可以缩写，日和年用逗号隔开，例如：december 18, xx或者dec. 18, xx。

2. 如果要写星期，星期要紧挨日期，它既可以放在日期前面，也可以放在日期后面，星期也可以省略不写。星期和日期之间不用标点，但要空一格，星期也可缩写，例如：thursday dec. 18, xx或dec.18，xx thursday

3. 天气情况必不可少，天气一般用一个形容词如:sunny, fine, rainy, snowy等表示。天气通常位于日记的右上角。

团队进行对都江堰景区及其古建的参观考察。首先来到都江堰景区管理局，为我们提供了一定的帮助，然后于中午进入进去景区。跳跃的喷泉，流动的溪水，耀眼的锦鲤，一切都与水有无穷的牵连。走过堰功道，是古朴威严的伏龙观,站在伏龙观上，对面就是宝瓶口，在次眼前看到的是滔滔的江水挣扎着，咆哮着而终被驯服的场景，于是，胸中怀浮云，沉日月，叹古今，感慨古人的伟大智慧。然后途经飞沙堰，来到安澜索桥，看着来势汹汹的岷江在鱼嘴处一分为二，然后走过惊险的索桥，来到内江岸边，继续前行。看到巨大的落石，上刻5.12地震纪念，心痛不已，然后来到闻名的二王庙，但是它却不像水利工程般坚固，在地震中几乎全部损毁，我想着也许是李冰父子重工程不重名利的体现吧。我们用相机记载下了这被无情的灾害所毁坏的古建。

游览完景区，为了获得更多专业的知识，我们走访了四川省古建筑设计研究院，这里，国家高级工程师、一级注册建筑师张东山院长接待了我们，告诉我们5.12大地震对我们的许多古建毁坏巨大，有不少修复难度极大，根据实际情况，将采取简单维护，修复，原址重建，迁移重建，拆毁等手段进行保护。

团队和都江堰市建设局约好于今天进行参观访问，重点办的工作人员热情地接待了我们，并把我们带到都江堰市区图，都江堰市区规划图前进行详细的讲解和介绍。我们了解到都江堰在5.12汶川大地震中受损严重，很多城区建筑因为此次灾害受到不同程度的损坏。根据具体受灾情况，政府出台了一系列的救助政策，灾民及时得到安置和救助。经过两年的艰苦奋战，都江堰灾后重建工程取得了相当显著的成就，在一定程度上远远超出预期目标，城区面积扩大，从二环延伸至二点五环，万人小区的建成使城市的重心外移，更利于市区的发展，新的商业区，居住区的建成也使都江堰的建设亮点不断，水街主题商业旅游区，上海援建区，成灌高铁都让都江堰的城市品位得到提升。努力建成世界级旅游城市，花园城市的建设目标，在成灌高铁的竣工之后更是得到了确定。可以说灾后都江堰依然美丽，以后将更加美丽。

When I was six years old, I began to go to school. The first school (which) I attended was a primary school. There were many subjects (which were taught in the school, such as Chinese, arithmetic, history, geography, drawing and so forth. Since I was (became) a student, I studied very hard.
