小学六年级上册英语作文范文10篇(汇总20篇)

Computers are affordable for almost all people nowadays. As a result, an

increasing number of college students take computers to their dormitory to

browse website, watch movies and play video games and so on. This phenomenon has

caused lots of public concern. Some people believe that computer does bad to

students’ health for college students spend more than five hours staring at

computer without break every day. However, for other people, they are positive

to students’ owing computers because students can search for the newest

information. Standing on my point, I’m more tending to the first opinion.

Reasons are as the following:

Firstly, computers will transfer students’ attention. If students take

computers on campus, they would spend much time on computer than on study. For

instance, lots of my classmates usually play computer for amusement once class

is dismissed instead of going to the library to read more books to enlarge their

knowledge circle.

Secondly, students spend lots of time on computers which hurts their

health. It is quite often seen that students stay in dormitory for almost a

whole day without any breaks playing computers. It is all known that computers

have radiation which hurts eyes and skin.

To be honest, students can use computer to search for the updated

information that they want. But for the reasons above, I firmly believe that

students shouldn’t bring computers to college.

我家养了一只可爱的小乌龟。我可喜欢它了，每天都去看它。

它和别的乌龟与众不同。坚硬的背壳上穿着漂亮的绿衣裳，水灵灵的小眼睛总是东张西望，小巧的嘴巴非常贪吃，快速灵巧的四肢跑起来可快了。

它可贪吃了。今天我看它一动也不动，趴在那儿，闷闷不乐，用可怜的眼神看着我，还不停地张大嘴巴好像向我要吃的。看着它可怜的样子，我立刻拿出小虾米，分出一小块一小块，放在它的餐盘上。它看见立刻抬起头，眨着眼，伸长脖子就开始狼吞虎咽起来，不一会就把小虾米一扫而光，看它吃东西的样子真可爱呀!

第二天，我发现盆里的水黄黄的，黄中带了一些黑点，一看原来乌龟又拉便便了。我只好清理了脏水，小乌龟在干净的水里又快活地游来游去。

我爱这只穿着绿衣裳的小乌龟，因为它给我带来了无穷的欢乐!

每一个家庭都有自己的家风。早在三国时候诸葛亮在《诫子书》中就这样说过“静以修身，俭以养德。”就是告诫后人要从宁静来提高自身修养，以节俭来培养自己的品德。 Each family has its own family style.As early as the Three Kingdoms, Zhuge Liang said in "The Book of Commandments" that "quietly self -cultivation, frugality to nourish morality." It is to warn future generations to improve their own cultivation from tranquility and cultivate their own morals with frugality.

杨洋从小就喜欢看书，不管什么时候.只要有书看，怎么样都行。她小时候曾经这样对我说：“爸爸，我长大了好想当图管理员哦!”我问为什么呢?她说那样的话我就有看不完的书了啊!多么简单朴实的想法，目的只是为了看更多的书而已。所以在阅读方面，我们从来都是鼓励她多读书.而且要静下心慢慢读。

那是杨洋还在读幼儿园的时候，一个礼拜天的中午。我们吃完了饭，都到外面聊天去了。我吩咐杨洋：“杨洋，认真吃饭，吃完了就出来玩”。“哦，知道了。”她回答说。没过一儿，她就出来了。“吃完了吗?”"吃完了。”她目光闪烁地回答。

我心里就想：今吃饭怎么这么快呢?于是就进房间来去看了一下.碗里光光的，是没有了.只是垃圾拦筐里多了个黑色的塑料袋，我一下就明白了。“杨洋过来!”我用严历的声音喊。“怎么啦，爸爸?”她畏畏缩缩的从外面走了进来。“你真的是把饭吃完了吗?”"是啊。“她低着头回答道。“抬起头来，看着我的眼睛在再回答!”她没有抬起头，反而低得更下去了，“爸色平时是怎么教育你的?”“勤俭节约。

”“还有呢?”"不能说慌话。”“那你做到了吗?”她羞愧地把头埋得更低了。过了一会儿，她抬起头来，对我说：“爸爸，我知道错了，我不应该说慌话骗你们，更不应该浪费粮食.因为每一颗粮食都来之不易。”我语重心长的说：“是啊，说谎话害的是你自己，就像喊狼来的那个小朋友一样.到后来没有一个人相信他。浪费粮食就更不应该了，任何东西都是通过付出辛勤的劳动而得到的。”

教育不仅仅只是这一方面，还有很多地方需要我们不断学习才能更好。我们会一起努力，争取做得更加优秀!

Humor is a flavor of our lives. Humor can soften relationship between

people; humor can adjust the atmosphere of different occasions; humor can bring

more fun and joy to our lives.

First, humor is very necessary in communicating with others because it can

soften relationship between people. In the process of getting along with others,

the occurrence of difference and contradiction is inevitable. Sometimes, when we

want to persuade others to agree with our points, we will find that our points

are easier to be accepted if we argue in a humorous tone.

Second, humor can adjust the atmosphere of different occasions. A person

having a good sense of humor is good at adjust the atmosphere. For example, in a

family, if the husband has a good sense humor, their family life would be more

harmonious because he can adjust the atmosphere in time to avoid the occurrence

of quarrel.

Finally, a person having a good sense of humor can bring fun and joy to

others. It is not difficult to find that a humorous person is always warmly

welcomed in any occasions because he can bring happiness to everywhere he goes.

In addition, staying with the humorous people, we will find that we will be more

positive and our lives will be more wonderful.

Therefore, all of us need to learn some skills of humor and use them

properly so that we can make our lives be more wonderful.

我们周围每天会发生许多大大小小事情，有一些事虽然很小，但是总会让我们记忆犹新，好像昨天刚发生的一样。

有一天上午，我上数学课一直处于跑神状态，马老师的话，我一句也没听进去。下午放了学，回到家做作业时，我不会的一些题没问也没想，就胡乱写的答案完事，第二天就把作业交了。

中午休息，马老师把我叫到办公室。我忐忑不安地站在那里，眼睛看到桌子上打满红叉叉的作业，我脸红了，慢慢地低下了头，心想：“这下可糟糕了，马老师肯定要狠狠地批评我了!”可是，马老师却心平气和地对我说：“你看看，错了这么多，上课的时候没有认真听，还是没有听懂?看看错题，自己想一想，错在哪里了?”我仔细一看，有的是把加法算成减法，有的是抄错了数字，还有的是不懂写错了，我惭愧极了，脸红的低下了头。这时马老师温柔的说：“曦曦，是不是有不懂的?”我赶紧点头，于是马老师耐心地又给我讲了一遍。还不时停下来，让我想一想。然后用眼睛温和地看着我，好像在问我听懂了没有。直到我会了，才讲下一题。最后马老师对我说：“你以后上课一定要认真听讲，做题时要细心计算。老师相信你一定会有进步的。”听了老师的话，我的心里暖洋洋的。走回教室的路上，感觉花园里的花儿也在不停地点头，好像在说：“你一定要表现好，不要辜负了老师对你的期望。”

虽然这是一件小事，但是让我知道了上课专心听课是多么重要啊!也让我体会到了老师对我的关心与鼓励。

勇气是一个真正的男子汉必备的品质。勇气不是天生就有的，是需要慢慢培养的。曾经一段时间，“胆怯”这个敌人伴随了我很久。 Courage is a real quality of a real man.Courage is not born, it needs to be cultivated slowly.For a while, the enemy "timid" accompanied me for a long time.

那时我九岁，在某一个早上，我的肚子特别痛，疼得我昏昏沉沉的，浑身没有一点力气。妈妈带我去医院检查。大夫为我进行了仔细的检查，并让我去抽血化验。当我听到要抽血时，我的腿都发软了，我从小就最怕打针了，记得有一次护士在我的头上扎了三针，都没扎进去，疼痛的感觉我至今记忆犹新……但没有办法，在妈妈严厉的眼神下，我勉强跟着妈妈去了化验室。

只见护士的手指间夹着一块药棉为我的手臂消毒，并用一根皮筋绑在我的胳膊上。随后又转身去拿针头。当她转过身来的时候，我感觉到她手中的针头怎么这么“粗”……心里想着那一阵阵巨痛正在狞笑着向我走来，我紧张得要命，手攥得紧紧的。就在针头快要接触我的皮肤的一霎那，我猛地将胳膊抽了回来，由于用力太大，差点摔个跟头。

护士生气了，说还算是男子汉呢，没见过我这样没有勇气的小孩。在羞愧不已的同时，我的心里还是很矛盾，就是鼓不起勇气。我犹豫着，是抽呢?还是不抽呢?不抽吧，我的病不但好不了，还得挨大人说;抽吧，又要忍受剧痛。在我的眼中，那只小小的针头已变得又粗又大。

我用企求的目光望着妈妈说：“我不想抽血。”妈妈说：“你已经是大孩子了，要有勇气。”这时，我也想起了爸爸经常对我说的一句话：如果有一件事，你很不想做，但这件事又必须去做，那么你就要鼓足勇气，克服困难，踏踏实实地去做。思前想后，我终于找回了勇气，把胳膊伸了出来。

这件事情过去快有三年的时间了，每当我想起这件事，我就对自己说：“恐惧只能增加你心里的负担，要排除万难，战胜恐惧。”勇气在人的一生中是非常重要的，无论干什么都需要勇气。我已经找回了勇气，终于战胜了这只纸老虎。

“时光如水，生命如歌。”在白驹过隙间，我们又送走了紧张的一学期，迎来了又一个暑假。

在这暑假里我一定要好好好好利用时间，不会把时间白白流失。

在放假的时候感觉真好。早上睡到十点多才睁开惺忪的睡眼。不紧不慢地穿着衣服，不用在担心爸妈的催促。细细地品味那武汉的风味小吃。空调吹来的凉风令我不由得想到同学。他们一定和我一样此时都在家享受着空调所带来的清凉。

放假的感觉真好。抱上一本闲书故意地从爸妈面前走过。他们的脸上挂着笑，似乎原来所反对的闲书，此时再看起来已经不闲了。

放假了，我也要先把作业写完，然后就能快快乐乐的玩了，我的暑假计划很充实，在暑假里，我要认认真真的学习，也要快快乐乐的玩，然后就去旅游，去黄山，去日照，去青岛，去郑州等等!

我们除了学习，最重要的就是身体，要是免疫力低，刚放假四五天就感冒了，岂不是白白浪费了一个假期?所以我要多多锻炼身体，多打乒乓球，俗话说得好：“每天锻炼一小时，健康生活五十年，幸福生活一辈子。”还有我们要吃晚饭要去外面走走，还有一句古话说的也很好“饭后百步走，活到九十九”。最后，我还要说，暑假，暑假，毕竟还是假日，我们也要玩一玩，放松一下。

啊!暑假真快乐呀!

Computer has considered to be one of the most important inventions in 20

century. It has brought many changes in this world. With the rapid development

of science and technology, more and more people have their own personal

computer. It’s not only can do the calculations at a very high speed, but also

can access to the Internet to get information from the outside world.

Computers play an very vital role in our daily life. They can do a lot of

things. Access to the Internet, you can find the answers to your questions, you

can do on line shopping without going outside. Computer has provided us lots of

convenience. There is no doubt that people can have a better life with

computer.

Some people worry about that someday computers may replace human beings.

Then most people will have no jobs. However, in my opinion, computers are not

replacing us. Even though computers can take over some difficult tasks that we

can not do. They are nothing but machines. They work for us. They will never

take the place of man.

今年国庆节，爸爸妈妈带我去上海旅游，上海真是个繁华的大都市。我们在熙熙攘攘的人群中逛完了南京路，又排队登上269米高的东方明珠，最后参观了上海市的历史陈列馆。一天的游览让我了解了很多上海的历史和现状，收益匪浅。然而当我们结束一天十多个小时的行程准备回宾馆时，疲劳的感觉更凶猛的充满了我的全身，两腿软软的，两脚酸酸的，每迈出一步都异常的艰难，真想现在就躺下来好好睡一觉呀。

我们在开往宾馆的地铁始发站上了车，正好有些空着的座位，这个时候有个座位坐着，真是一种幸福，我惬意的闭上眼睛回想着一天的所见所闻，不知不觉中睡着了。不知过了几站路，我被一阵阵吵闹声惊醒了，原来乘客已经把每一处空隙都塞的水泄不通，简直快要把车厢撑破了。我突然发现在离我不远的地方站着一位两鬓苍苍的老太太，她一手吃力的抓着扶手，一手领着一位五六岁的小女孩，可能是她的孙女吧，由于地铁的提速和刹车，老太太在人潮中前后左右的打着趔趄。然而，就在她旁边的座位上几个年轻人却旁若无人的嬉笑打闹着，根本没有给这位老太太让座的意思。我不由的想到老师和爸爸妈妈平常对我的教育，要尊老爱幼，发扬中华民族优良的传统美德。我站起来，搀扶住老太太说：您请坐，老奶奶。老太太抬起头感激的对我说：你真是个讲文明懂礼貌的好孩子。这时，车厢里的人们都朝我投来敬佩的目光，连刚才那几个打闹的青年也低头无语了。今天的地铁路程好像没有原来那样远，没有多久就到达了我下车的地方，我开心的和爸爸妈妈回到了宾馆。

我的一天

I got up early this morning. I cleaned my room. I opened the window and

aired the room. I picked up the paper and swept the floor. Then I made the

bed.

我今天很早起床。打扫了房间。我开窗通了风。我捡了地上的纸，扫了地。然后我整理了床铺。

I played computer games. We had lunch at 12:00. We had fish for lunch.

我玩了电脑游戏。我们在12点的时候吃了午饭。我们吃了鱼。

After lunch we went to the park. In the evening I did my homework. We had

delicious food for supper.

午饭后，我们去了公园。傍晚的时候我做了作业。我们晚饭吃了美味。

I was very happy today.

我今天过的很愉快。

真好。又到双休日了！我睡够懒觉刚起床，就听见妈妈在喊我：“洋洋！”“唉。”“起床了。”“起来了。”“一会儿吃完饭，你坐班车去姥姥家吧！”太好了！姥姥家住城里，我巴不得天天去呢！

我刚到车站，班车就来了。车上，人很多，也很挤，但大家都很守规矩。“来，小朋友，坐这儿吧。”临近车门的一位胖叔叔忙站起来给我让座。怎么好意思呢，“不了，您坐吧！”我推让着。“你坐吧。”胖叔叔早已站了起来，向座儿后站去。也许叔叔快到站了吧，那我就不客气了：“谢谢叔叔！”他冲我一笑，摆了摆手。我真幸运！一上车就有座儿。我美滋滋地坐下了。

一站，两站……，那位胖叔叔依然远远地站着。我有些不好意思：人家是有意把座儿让给我，我还得意呢。这时，一位白发老爷爷上车了，我立刻站起来：“老爷爷，您坐我这儿吧！”“孩子，你坐吧。”“不了，您坐！”“唉——，这孩子真懂事儿！”老爷爷万分感激地坐下了。

过了一站又一站，老爷爷几次让我坐回去，我都婉言谢绝了。虽然腿有点累，但心里却很舒服，很愉快：我没给少先队员抹黑！妈妈知道了，也一定会夸我的……我正在胡思乱想，车停了，一位大姐姐扶着一位拄着拐杖的残疾大妈上车了。“大妹子，你坐这儿吧。”大妈吃力地摆摆手。“来来来，你站着不方便，我没事，快到站了。”“老爷爷，谢谢您！”那位姐姐说。“还谢啥呀，快扶她坐下！”大妈吃力地坐下了。

班车在走走停停中，又过了好长时间，终于到达市内终点站了。人们在说笑声中下车了。无意间，我看见那位胖叔叔和那位白发老爷爷，都在刚刚下车的人流中。他们走路很吃力，但看得出来，脸上都洋溢着笑容。

“洋洋——！”“姥姥！”我兴高采烈地奔向早已等候在不远处的姥姥。

我有一个帅气的同桌：在他那高高的鼻梁上架着一副大大的黑框眼镜，一张薄嘴突出了他英俊潇洒的个性。 I have a handsome table on his tall nose bridge.personality.

他这个人，最不爱回答问题。一到了上课的时候，他就像一个泄了气的皮球。看，四周的同学生龙活虎，跟着老师的思路走，可他，却萎缩到一块儿，打蔫了。唉，真拿他没办法。

他虽然不爱回答问题，但是他却乐于助人。

记得上次老师上完了课，让同学们翻阅一下自己作文的参考书。我一听，顿时愁眉紧锁——我的作文书没有带。这可不得了，万一老师检查到我没带书，我就……我心急火燎得想：“我的救星在哪里?”这时，他看到了我心急如焚的样子，又看到了我那涨红的脸，霎那间仿佛明白了什么，静静地从书包里翻出了另一本作文书，慢吞吞地递给了我，嘴唇微微向两边抽搐了几下，算是给我一个笑。我那起伏的心顿时平静了下来，我的救星给我雪中送炭来了。我感激不已。

“以后没带书尽管管我借，我这儿还有好几本儿呢，”是、他边说便把那些书拿出来给我看，“我这书的种类可全了，你想看什么，就尽管借喽!”

好一个“书库”哦!他为了求知，买下了很多书籍，他不仅自己看，还愿把这种快乐分享给他人。

在这几天，附近邻桌也同我谈起他，说他不仅热爱读书，心肠也好，十分乐于助人，有不会的题他总会给别人耐心讲解。我真的越来越佩服他了，他真的是我的楷模!

我结识了这样一个同桌——一个善良，乐于助人的同桌。他让我明白了有好东西应分享的道理。我应该学习他那种慷慨无私的高尚品格。有这样一个好同桌，我怎能不感到欣慰呢?

Timeflies like an arrow before we realize it .It is known that nothing is

more precious than time. The good old proverb "time is money" reminds us that

time is valuable. When time goes by, it will never return. However, it is a pity

that some people dont make full use of their time .They spend a lot of time in

sleeping, chatting, playing computer games or other unmeaning matters. . They

dont realize that wasting time is actually equal to killing themselves. They

always regret not having made great achievements. One of the reasons may be they

do not make good use of time. Therefore, in order to be successful, they should

first get into the habit of being on time. It’s a sign of cherishing time. Dont

put off what can be done today until tomorrow. Being lazy will eventually lead

to failure. Dont wait, because you dont know how long it will take when you

put off your plan.

The more we are aware of the significance of this famous saying, the more

benefits we will get in study or job.

妈妈爸爸都夸我长大了，因为我可以做很多很多的事。

比如说：有一天，爸爸妈妈都不在家，门外响起“咚咚”的敲门声，我问“请问您是谁”，外面的不知名的人答道：“我是琳琳”，哦，原来是琳琳姐姐，请进门。我给琳琳姐姐倒了一杯热水。我问：“有什么事吗”？琳琳姐姐笑着说：“你能陪我玩会吗”？“可以”我高兴的说。我锁上门，带去我的房间，我把我的芭比公主拿出来和小叮当……，过了一会儿，我的小爱丽丝走了过来，长毛，带着蝴蝶结。

我好高兴，因为我可干很多很多不同的活了，长大的过程其乐无穷的，也包含着酸甜苦辣。

我是人类的载体，我的名字叫地球。50万年前，我的身体是那样健壮，可是现在，我所哺育的人类发达了，他们就开始对我进行破坏了，使我的身体一天比一天衰弱。哎，人类真是太忘恩负义了!

现在，我身上的淡水，几乎都变混浊了。人类不断地把污水排放到河流中去，造成了我身上内陆水域的污染，使病毒不断地蔓延，只有30%的人类才能喝到安全卫生的水，洁净的水成了人类生死攸关的大问题。解决水质污染，使我更加年轻。人类啊!听听我的劝告吧!

前几天，我老远见到了太阳。我对他说：“太阳公公，请不要再让您那强烈的紫外线照射到我的身上吧，那些人类受不了啊!”太阳说：“你不是有一把大伞——臭氧层可以抵挡住我的紫外线吗?”这时，我难过地说：“哎!别提了。由于人类不注意保护大气环境，工厂的废气排放到空气中，再加上近两个月北约对南斯拉夫的狂轰滥炸，使大气中粉尘进人人体，给人类以严重的威胁，而且使大气中的臭氧层进一步被破坏。现在，在南极上空已经出现了“空洞”。“哎，这可怎么办呀?”太阳愤怒地说：“这都是人类一手惹下的祸，他们这是自作自受?应该让他们汲取教训。”说完，便生气地离开了。这时，我痛苦地说：“人类啊，不要把这些当儿戏了，如果不加以治理，后果将不堪设想啊!”

同时，我发现我的皮肤正逐渐由以前的绿色转变为黄色。这是什么原因呢?为了解开这个谜，我去太阳系超级医院作了检查。听大夫一说，我才明白了。原来，这是由于人类对森林资源不断地破坏，对草原过度放牧引起的后果。我身上的黄河流域已造成了严重的水土流失，成为最严重的环境问题。目前，我身上的黄色皮肤正在不断蔓延，绿色皮肤不断减少。沙漠逐渐吞并了我的全身。听了大夫作出的诊断结果，我简直快要哭了。我哀求医生说：“医生，快治好我的病吧。”医生却说：“人类是你的主宰，要想治好你的病，靠的是他们呀!”

我呼吁人类：保护环境吧!保护森林吧!让你们的生命摇篮重新恢复往日的风采吧!

总评：“地球”面临着什么灾难?如何保护地球?这是当前人类亟待解决的问题。本文小作者通过丰富的想像，运用变形的手法生动地讲述了地球所面临的灾难的原因，使人们充分地认识到保护地球的重要性。

作者还运用了对话的方法，把枯燥无味的道理生动形象化了，使人仿佛感觉到了一个童话世界。同时能用一些通俗易懂的道理，激起人们对保护地球重要性的认识和重视。
