三年级下册第一单元作文：家乡的美景

我的家乡在江西，这里十分的美，从景到人都有一种自然的美，我来说一下我的家乡吧。

江西这里，有着无边无际的田野和花海，金黄的油菜花，黑白相间的蚕豆花，雪白的荞麦和萝卜花，争奇斗艳，争先恐后的，想要第一个绽放出最美的花，带给人们一种质朴的美感。

不仅仅是田野里，就连乡下人家的院子里都有一种独特的美。

院子里，人们一般会种一些花花草草，凤仙花、白百合、茉莉花、薰衣草、夜来香，有些人家，还会插一根杆子，让牵牛花，金银花的藤缠绕上去，藤爬上了柱子，就像一条青龙缠绕在柱子上，当藤结出花时，柱子上就像绑上了一条彩带，真是美丽极了。

还有些人家，在屋顶上，种上一些喜欢阳光的植物，从远处看，房子就像一顶绿色的帽子，这些植物还起到了给房子降温的作用，就像一群战士，是房子不受太阳的袭击。这些植物既起到了美观效果，还可以给房子降温、防晒，真是一举两得。

去湖边里走走，常常会看见几棵苍天古树屹立在江边，就像哨兵一样，守卫着湖边的草地，这些树一年四季都站在这里，不惧春天停不下来的大雨，夏天骄阳似火的炎热，秋天的一片荒凉的寂寞，冬天北风凌冽的严寒，真是勇敢啊！

我爱我的家乡，爱这里无边无际的花海到极其普通的院子，更爱我在这里的美好回忆。

暑假英语作文——暑假回忆

A new term began. Students all returned to school and met again. They were talking about what they had done in the holidays. I was much happier. I couldnt wait to tell my story. Now its my turn. I told them I got a job in a restaurant. I worked as a waitress. They didnt believe at first.

"Yes, its true. "I said," I really had a hard time at the beginning. But several days later, I could do a good job. I earned six hundred yuan this holiday. "They all looked at me with their mouths open.

【参考译文】

新学期开始了。学生们都回到学校，又见面了。他们正在谈论他们在假期里做了些什么。我开心多了。我等不及要讲我的故事了。现在轮到我了。我告诉他们我在餐馆找到一份工作。我做过女服务员。他们起初并不相信。

“是的，这是真的。”我说：“我一开始真的很难过。但几天后，我可以做得很好。这个假期我赚了六百元。”他们都张开嘴巴看着我。

有一天，魏国有名的射箭能手——更羸与魏王去郊外打猎。一只大雁从远处飞来，边飞边鸣。更羸指着大雁对魏王说他不用箭，也能把大雁射下来。结果大雁真的被射了下来，更羸就解释地说：“它飞得慢，叫的声音很悲惨。飞得慢，因为它受过箭伤，伤口还没有愈合，还在作痛;叫得悲惨，因为他离开同伴，孤单失群，得不到帮助。它一听到弦响，心里很害怕，就拼命往高处飞。它一使劲，伤口又裂开了，就掉了下来”从中，我知道了更羸观察细致、思考认真。

读了这篇课文，我明白了只要拥有非凡的观察力，准确的判断，不可能的就会变成可能的。在生活中我们也要像更羸一样善于观察，善于思考。

nce upon a time. There was a house. Beside the house there was a bird cage. One day a cat went to eat the bird, So the cat jumped and hit the bird cage. The bird cage fell down to the ground knocking the bird cages door open. The bird then flew away. So the cat started to chase the bird and the dog chased the cat. However the bird flew on top of the tree. So the cat started to climb the tree and the dog barked at the cat. Before the cat could reach the bird, the bird flew away. this caused the cat to fall out of the tree. The dog then ran away, The bird quickly flew back into his cage and the man from the house carried him safely home.

In current society, people have known the importance of keeping healthy and good life habit. In the past, people ate three meals at home, and they ate more vegetables and less meat and fish. They were very strong and seldom went to see doctors.

Now life is better, people eat more meat, fish, eggs and other food with more fat. They often go out for good meals with their families and friends. But they get easy to be ill, Why?

I think more meat and fish, less exercise are bad for health. Good rest, less meat and fish, more vegetables and enough exercise are good for health. So I exercise every day. My eating habits are pretty good. I eat a lot of vegetables. I eat fruit and drink milk every day. I drink a cup of water 15 minutes before each meal and eat much vegetables and fruit. Of course, I love junk food, too, and I eat it once a week. And I sleep nine hours every day.

january 28 2010 it was the third day of our winter holiday. today， there are many business in my mother‘s company. so my mother told me to help my uncle who is the manager of my mother’s company. i sat in my mother‘s office and help her answer the telephone. while i was free， i was writing my homework. although i also have a lot of time to do my homework， i still do it. because in my mother’s office， i had nothing to do. if i did nothing， i was wasting my time and my life. i can‘t do the foolish thing. we should take good use of our time.

我有一个漂亮的房间，那里有闹钟、玩具、和写字台。但往往我想我的房间和现在不一样。

我希望我的房间是超市，里面有巧克力、牛奶......我要什么，那就有什么，多好啊！

我希望我的房间是魔术屋，写字台是又香又脆的饼干，窗户是软绵绵的蛋糕，水管流出的全是甜甜的可乐汽水，那多好哇！

周六周日的时候，我希望我的房间是游乐场，书架是滑梯，本子是草坪，椅子是秋千，小床是健身器材。然后我会把灰姑娘、白雪公主请出来，和我一起游戏一起欢笑。

想完了这些，我最最喜欢的还是我现在的房间，因为在这里，我可以读书，思考，让我的理想从这里开始飞翔！

我的家乡坐落在农村。那是一个美丽、幽静的地方，清请的河水，五颜六色的野花和各种味道的野果，给我留下许多美好的回忆。

我家屋后，有一座座高耸入云的山。远远望去，直入云霄。山上长满了松树、樟树、榆树、冬青树等许多常见的树。山上的竹林里，还有许多鲜嫩的竹笋，成群结队的从土里探出头来。人们拿着锄头，拎着袋子纷纷上山挖竹笋。

我家门口，有一条清清的小河，泛着淡淡的绿色，好似一块无瑕的翡翠。河里不时隐隐约约地冒出几条小鱼来。它们轻盈地摆着小尾巴，真可爱!河底，还有许多大石头，看上去很光滑!

清晨，我被树上唱歌的鸟儿唤醒，“叽叽，叽叽喳喳，叽叽!”那歌声真好听，让那些沉睡一天的人们，赶快起来，开始一天的忙碌。种秧苗，喂鸡鸭，各自忙着自己的工作。

看着这熟悉的景象，使我回忆起了以前的童年时光：在新春佳节，我和一些小伙伴在门前的空地上放鞭炮。找来一些罐子，点燃火柴，在鞭炮的顶端一碰。黄黄的火花突然冲出来。我用双手拢住耳朵，飞快地向外跑去。“啪”的一声，从鞭炮里冒出一束火光来，直奔云天。我心想：真危险，幸好我跑得快，吓死我了。

家乡乘载着我满满的回忆，我爱我的家乡。

我的家乡天津是个现代化的大都市，这里高楼林立，还有极具地方特色的小洋楼组成的五大道，而且许多清朝末年的古建筑也被完整地保留了下来。天津有很多古街，虽然都是十几年来被陆续翻新的，但它们都保留了中国古代的建筑风格，原原本本地仿造的。古文化街就是其中最有特色的一条街。从很远的街口就能看到古文化街高大的牌楼，街上的建筑物青砖绿瓦，是天津著名的旅游景点。

现在天津越来越美了，如果你仔细观察就会发现，天津的街道变宽了，草地和树木也变得茂密了，漂亮的高楼大厦也变得越来越多了，海河的水变清了，鱼儿变多了，无论春夏秋冬，都有人到海河里游泳垂钓。

这就是我们的家乡，非常的美丽，等我们长大了，我们也要为家乡做出自己的奉献，让家乡更加美丽迷人。

On the twenty- fourth of december everyone gets excited for it’s the day before christmas which is called christmas eve. the children are usually sent to bed early and are warned that “santa claus will only come and give you a present if you be good.” the younger kids actually believe that santa will come down the chimney on the sleigh that’s pulled by his reindeers. food like short bread and beer are prepared for santa when he comes, however most times parents just eat them. some children put socks and sacks up for the holding of the presents (that their parents put in).

Rise and shine on christmas morning! the children are always the first ones to wake up, some even do at four. present wrappers everywhere! they look into their presents with a big smile on their face and oh dear….i hope no one’s disappointed. i feel sorry for anyone that got pink underwear. children play while dinner is prepared by the adults. the christmas dinner are usually eaten together by relatives. the tradition of christmas pudding and roosters are usually eaten with deserts afterwards. the rest of the day is usually games and fun before the good days all come to an end.

I wish everyone a merry christmas and a happy new year!

“陈瑜，你赶紧去一壶水!要不然我就把电脑的线给拔了!听到没有!”

我有预感，妈妈已经生气了，而且还很生气!所以，我立刻去烧水了。烧好了水后，妈妈终于不生气了，还让我再玩了一会儿电脑呢!

我眼中妈妈就是这样，一点一点的把我带大的。你们说，我眼中妈妈好吗?

The Cause of fire

As we all know, fire is one of the most terrible killers in our modern society.We know that fire is mainly caused by smokers, followed by defective insulations and children playing with matches.In 2002 ,thousands of fire happened all over the country, of which 50 percent was caused by smokers who left cigarette-ends everywhere.Those who smoke should make sure that the cigarettes are stubbed out before being thrown away.Also, smoking should not be allowed in public places.30 percent of fire was caused by defective insulation. Workers should know the importance of good insulation for people’s lives.At homes we must pay special attention to electric wires and make sure that they are safe.20 percent of fire are caused by children playing with matches. We should warn children of the danger of playing with matches.

No matter what type of the reason it was, there was one thing in common:carelessness.So if everyone in the country is careful enough, more fire could be avoided.

我们都知道火灾是现代社会最可怕的杀手之一。火灾主要是由吸烟者、绝缘不良和孩子玩火柴引起的。在2002年，全国发生了成千上万起火灾，其中50%是由于吸烟者随便扔烟头引起的。那些吸烟者应该在扔烟头前确保烟头已经被掐灭。而且，公共场所应该禁止吸烟。30%的火灾是由于绝缘不良引起的，工作人员应该懂得绝缘对人们的重要性。在家里时我们应该尤其注意电线，要确保它们的安全性。20%的火灾是由于孩子玩火柴引起的，我们应该警告孩子玩火柴的危险性。

不管是哪种类型的原因，它们都有一个共同点：粗心。因此如果国家中每个人都足够细心，那么更多的火灾是可以避免的。

今天的英语课上，我们玩了一种新游戏，规则是：老师抛出泡沫做的筛子，那是个很大的筛子，像足球那么大个，不过是四方形的。谁抢到筛子，谁就读5个单词，读完5个单词有奖励1个星星。刚开始老师走到哪里我们就跟到哪里，气得老师说：“回去！这样违反了游戏规则。”我们只好灰溜溜的回到自己的座位上。这时，老师一挥，大筛子朝中间的潘晨艺砸过去，他伸手接住啦！我旁边的黄子洋叹了口气说：“唉，没抢到，真是的。”随着老师抛筛子位置的变换，我们也跟着移动，好几个人都抢到筛子了。 我像毛毛虫似的扭来扭去的接，可就是接不到。唉！大家正玩得热火朝天呢，老师说：“游戏时间结束，现在开始复习功课。”唉！真扫兴！大伙儿唉声叹气的回到座位上。因为没接到筛子，这节课我才得到2颗星星，下节课我要加油了！
