Every other distance on the Great Wall is a beacon tower, like a giant hand in hand, shouldering the defend the burden of the central plains of China.

A sea of people on the Great Wall, there are many "laowai"! Unconsciously, we have climbed to the first war, this reminds me of the "war drama leud" story.

今天，我们游览了世界闻名的古建筑奇迹——长城。

长城是中华民族的象征，它全长一万两千多里，是世界上最伟大的建筑之一。我们游览的是长城八达岭段。当车行到离八达岭不远处时，就已经看到了气势恢宏的长城，随着连绵起伏的山脉向远处曲曲折折地延伸，像一条龙在云雾缭绕的山峰中飞腾。长城上每隔一段距离就是一座烽火台，像一个个巨人手牵着手，担起了保卫中原大地的重任。

我们从长城脚下往上爬，长城并不像我想象的那样陡峭，而是由许多缓坡连接起来，在比较陡的地方都筑有阶梯，阶梯的两旁和中间还装有扶手，一点儿也不难爬。长城上人山人海，还有许多“老外”呢!在不知不觉中，我们已经爬到了第一个烽火，这里让我想起了“烽火戏诸侯”的故事。过了烽火台，我们又继续向上攀登，在山间云雾里，我隐隐约约看见对面的山上有用钢板做成的“同一个世界，同一个梦想”的标语牌。接着往上爬，我们看到了一座碉楼，爸爸说：“这是哨塔，古代哨兵就在这里放哨。”过了哨塔，我们就往回走，来到了“好汉碑”。好汉碑上有毛主席的题词——不到长城非好汉。我们全家在这儿留了个影，便回家了。

“不到长城非好汉”，今天我爬上了长城，我也当了一回好汉，真开心啊!

However, my favorite animal is the highest level of protection in our country.

Because of his long fat, very cute. The giant pandas main food is bamboo. But because people cut down trees, the giant panda food less and less, so we should protect trees.

因为他长的胖胖的，很可爱。大熊猫的主要食物就是竹子。但是由于人们砍伐树木，使大熊猫的食物越来越少，所以，我们要保护树木。还有一些动物，因为不适应环境，已经快要灭绝了。所以，我们还要保护环境爱护大自然。让我们和动物能够和谐地生活在这个地球。同学们，动物是大自然给人类的无价之宝，是我们人类的朋友。它们的生死与我们的生活息息相关。

动物的大量灭绝会造成生态的严重不平衡，从而使我们人类的生存环境遭到破坏。让我们从我做起，从现在做起，保护动物。让世界变得更加美好吧!

这次下棋，我懂得了不能因为一点事而灰心，要仔细观察。

She is very busy today, just like a busy bee. In the morning, I had two seccsions and after that I had a lesson for my IELTS. I dont even have my lunch. There lots of people in my IELTS class and most of them came from India. The reason why they want to attent this course is similar to me. Right now, I feel exhausted and dont want to work, but I still have lots homework to do.

I also have some other problem. Last term, I decided to start my new term in Newcastle, and asked Jhon to give my money back. And now, I have changed my mind, so told Jhon I did not want my fees back, but she told me the check had been sent out for almost two weeks. I havent received my check until now, and I told her the truth. Finally, she said she would help me to ask finaNcial officer to give me another letter, and then after I sign that form everything will be all right. What a absurd world it is. If I had not asked Jhon to give my fees back, it would have become much easier.

If my boy sleep quietly, he will see the busy bee, when it has made its honey fine, dancing in the bright sunshine. If my boy will slumber, angles without number will draw near, so fair and bright, for they only come at night.

我的家乡在南京，是一个山清水秀、风景如画的城市。它可是六朝古都、历史名城。有着说也说不完的故事。

春天来了，南京城里显现出一派生机勃勃的景象。小草露出了头儿，绿油油的紫金山像披上了绿色的新装，在春风中翩翩起舞。树木抽出了新芽儿，长出了嫩绿的叶片儿，微风吹来，树叶“沙——沙”直响，像是在奏一支交响乐;又像是在向人们点头问好，美丽极了。桃花儿也开了，远远望去，红霞山峦交相辉映。

夏天，树木长得郁郁葱葱。那金色的阳光像一把把利剑，割开浓密的树叶，给大地织了一件五彩斑斓的披风。知了放开嗓子尽情的歌唱，好像再为夏天的到来鼓掌。

最美丽的是南京的秋天。秋天，庄稼熟了，青草、树叶都变黄了，片片树叶从树冠上悠然而下，像蝴蝶在飞舞。山路上满是落叶，踩在上面“嚓——-嚓”直响，非常有趣。紫金山上那树叶，每一位游人走过之后，头发上都会有一片或两片的落叶。我的家乡在南京500字

南京最有名的地方便是雨花台。雨花台的特色也是出奇的多，有雨花石、雨花茶等等。雨花石各种各样，有透明的，有洁白的，还有镶嵌着一丝丝“琥珀”的。我最喜欢的是“梅花俏”，“梅花俏”通体透明，里面还镶嵌着一个个绽放的梅花，好看极了。

雨花茶也是很有名的。它肉质肥厚，皮儿薄，泡起来香味异常，恨不得多嗅几下。雨花茶的制作工序也是很严密的：从采茶到制出来的茶叶，几乎得十道工序。采茶需要十几个人，而制作就更严密了，一道工序得2到4人做，筛选，包装等等，都是要耗费很多人力、物力的。

我爱我的家乡，爱他的山，爱他的水，爱他的历史文化————长大以后，我要用自己的智慧和汗水，让我的家乡变得更加美丽!

星期天，爸爸带我和妈妈到公园一起玩耍，爸爸说趁今天天气好，要自己开车带我们去，我和妈妈都开心不已，要知道爸爸以前都很少带我们出去玩。

我们收拾好东西就准备出发了，结果才出发不久路上就堵车了，原来星期天出来逛街的人这么多，结果导致路上堵车了，妈妈不禁叹气道，城市什么时候才能解决堵车问题呢?，一家人原本出来游玩高兴的心情立马被浇灭了。

这时候，我突然有一个想法，要是能发明一种空中汽车就好了，汽车可以在空中飞行，不用占用路面道路，这样子就解决了路面拥堵的问题，人们就不会那么焦虑了。最好汽车是充电式的，也不会对空气造成任何的污染，真是安全又卫生。

我把这个想法告诉了爸爸妈妈，爸爸提出了问题，要是开车司机的技术不行怎么办?人们在空中乱丢垃圾怎么办?这时我就跟爸爸说驾驶员可以是机器人来开车，机器人对产生的垃圾自动分类。这样问题就解决了。

这是妈妈在旁边直夸我是一个有想法的孩子。我在心里想，我将来长大一定要成为一名科学家，发明许多高科技，解决人们的出行问题，使人们的生活更加美好。

Recently for a period of time, always foggy weather, rose up in the morning, the beautiful scenery around would become very fuzzy, the news has been reported on the fog haze weather appeared frequently and brought serious consequences, the fog haze weather has seriously affected the air quality, affect peoples normal life.

In recent years, the haze weather not only seriously affected the quality of the air, but also easy to cause the main source of diseases such as asthma. Haze weather, the air in the contains some tiny particles of dust, these tiny particles is we cant see with the naked eye. These tiny particles is enough to make people have lung disease. They are, can be called is invisible killer. So, what exactly is a haze weather caused by what? Haze weather is really made from vehicle tail, the cooking of the lampblack, and smoking of tobacco, fireworks smoke formation, causing the haze weather.

Dont say fog weather is killer, not to mention the fog haze weather very terrible, in fact, the real murderer or we humans, is dont know how to protect the environment, human is human to destroy their homes, therefore cause haze weather, these are human take the consequences.

, of course, the present situation cannot be redeemed, we still can prevent fog haze weather. We can change the car to ride a bike; Can not stir-fried vegetables, stew; Can quit smoking or can finish smoking tobacco cigarette butts into the trash; Can put less fireworks; Also can plant more trees and flowers, to purify the environment. Only choose low carbon life, we can prevent the occurrence of haze weather. Sometimes, I really hope that the car is not smelly fumes, which come out of but a faint fragrance, spit out the chimney is not thick black smoke, the glittering and translucent dewdrop, instead. I wish our home can become more green trees, flowers and more red, a bird singing more beautiful, more elegant.

I believe, only if we take action, starts from oneself, our dream will become a reality, let us work together to protect the environment, protect our homes, let haze weather no longer harm human, make our home more beautiful.

最近一段时间，天气总是雾蒙蒙的，早晨起来，周围原本美丽的景物变得十分模糊，新闻上也频频报道雾霾天气的不断出现而带来的严重后果，雾霾天气已经严重的影响到了空气质量，影响到人们的正常生活。

近年来，雾霾天气不但严重的影响了空气的质量，更是容易引发哮喘等疾病的主要来源。雾霾天气的空气中，包含了一些尘土形的微小颗粒，这些微小的颗粒是我们用肉眼无法看见的。这些微小的颗粒足以使人们得上肺病。它们，可称得上是无形杀手。那么，雾霾天气究竟是由什么而引起的呢?其实，雾霾天气就是由汽车尾、炒菜的油烟、还有吸烟吐出的烟、烟花的烟形成的，从而引发雾霾天气的出现。

不要说雾霾天气是杀手，更不要说雾霾天气很可怕，其实，真正的凶手还是我们人类，是人类不懂得保护环境，是人类要破坏自己的家园，所以才引起雾霾天气，这些都是人类自食其果。

当然啦，现在的局势还是无法挽回，我们还是可以阻止雾霾天气的。我们可以把汽车改成骑自行车;可以不吃炒菜，吃炖菜;可以戒烟或可以把吸完烟的烟头仍到垃圾桶里;可以少放烟花爆竹;还可以多种植花草树木，来净化环境。只有我们选择低碳生活，才能阻止雾霾天气的发生。有时候，我真希望，汽车里喷出来的不是难闻的尾气，而是淡淡的芳香，烟囱里吐出来的不是浓浓的黑烟，而是晶莹的露珠，。我真希望，我们的家园能变得树更绿、花更红、小鸟的歌声更动听、更悠扬。

我相信，只有大家行动起来，从自身做起，我们的梦想一定会成为现实，让我们大家一起努力，保护环境，保卫我们的家园，让雾霾天气不再危害人间，使我们的家园更美好。

今天我学了《奇怪的大石头》这篇课文，感觉李四光爷爷太伟大了，仅仅是一块大石头，他就能追问不休，问了老师，问了父亲，一直到长大了都还在问。这石头简直就像我们的《十万个为什么》，引导李四光不断成长，最后居然发现了震惊全世界的“长江流域有大量第四冰川活动的遗迹”这一研究成果。

这一成果的源头是什么呢?一块大石头而以。

我们天天都可以看到石头，没什么感到奇怪的呀!为什么李四光爷爷小时候就能不停的问个不停呢?也许是因为它是坪地上的唯一的一块吧。

想到最近爸爸讲的牛顿发现万有引力的故事，也就是一个苹果掉到脑袋上，居然引导他发现了万有引力定律。苹果和石头一样，都很常见，很普通，可他们都由有重大发现。为什么呢?我就没有向李四光那样爱动脑筋。有一次，我做数学题遇到了难题，心想妈妈反正会教我的，非要让妈妈和我一起做，妈妈没办法，只好给我慢慢讲解，和我一起做出来了这个难题。

做事不认真，作业常常因粗心而做错——这是我身上典型的缺点。比如作业常记错，标点常漏掉，为此我挨了不少批评，可就是改不掉。

我要向李四光学习，和他一样爱动脑筋，碰到困难，虚心向老师、同学请教，努力开动脑筋，认真做好作业，打好基础，长大做一个有用的人。

I always feel tired after eight classes a day, so my dream school starts at 8:30 a.m. and ends at 3:30 p.m. There are three lessons in the morning and two in the afternoon. We can choose our favorite lessons to learn. We can spend more time doing some outside reading. The students do after-school activities for one and a half hours every day. We needn’t do a lot of homework. We are all happy to stay at school.

Besides that, my dream school looks like a big garden. There are many kinds of flowers around the modern buildings. Sweet perfumes are diffused all around. If I want to have a rest, I can lie on the grass, listen to music by the lake or look out at the flowers from the classroom windows.

The teachers here are kind and helpful. They are not only our teachers but also our good friends. The students are polite and friendly. We all know how to keep our school clean and tidy. There is no litter around the campus.

I love my dream school. We will grow up to be happier there.

“咚咚咚”，小猴边敲锣边喊着，“开会了，大伙快来开会了”。森林里的动物听到喊开会了，就从四面八方赶到开会地点。

老虎是森林之王，它开始发话了说：“最近有些群众反映说‘有些个别动物家的环境很差，搞得臭哄哄的’所以我决定带领大家来一次检查，来评选环境优秀奖”大家听到老虎的讲话，热烈的鼓起掌声。

第一个检查的是小兔的家，它家搞地干干净净，整整齐齐，连洞口也很整洁。接着是小猴的家`狮子的家……，它们的家都很干净，当检查到小熊家时，它家里脏脏的，臭哄哄的，到处堆满垃圾袋，大家马上起哄的说：“最差奖应该给小熊”。动物们都用石头扔向小熊，小熊委屈地说：“如果不是我每天到处捡你们扔的垃圾，你们的家哪有那么干净”。大家听到小熊的话都低下了头。

三年级下册第二单元作文：五年后的家乡

五年后，你再来我的家乡看看吧。小区周围不停冒黑烟的烟囱不见了，取而代之的是一个个可爱的卡通人物，变换着不同萌萌哒的姿势欢迎你。也许你会问：那废气哪儿去了？你看高空中，那一座座彩虹桥，就是废气处理器的功劳。

我带你到楼前的小河走走吧。你不要用手捂着鼻子，先前的恶臭黑水已经处理了；你仔细闻闻，迎面扑来的是河边花草树木的幽香，再看那小河里，泛白的死鱼和乌七八糟的水草都不见了。在清清的水面上游荡的是一只只漂亮的小水鸭。突然扑通一声响，你不要害怕，那是鲤鱼在河中撒欢儿呢。河边一群群的鱼儿在和小虾嬉戏，人们悠闲地坐在河边钓鱼，下棋，聊天……

那边有社区学校和游乐园，小孩子们放学后都在里面玩乐，有专门的机器人保姆看护着他们。他们放学、放假后可以尽情地在那里玩，不再被锁在家中学习，或者送进特长班。那里是孩子们的天堂，家长可以无忧无虑地去上班，不再担心孩子从楼上掉下来或者奔波在各个补习班中。

看那宽阔的马路上，再看不到冒着尾气的汽车，它们哪 里去了呢？都走地下通道了。上班族骑着自行车出行，既环保还锻炼身体。不再把宽阔的马路挤成麻花了。

我的家乡一天一个样的变化着，五年后会更加美好，人们正在朝着那个方向努力。
