保护环境善待地球

众所周知，我们只有一个地球。地球是我们的家园。我无法想象，如果地球消失了，人类该怎样生存。

我们的生活不能离开地球，所以，请善待地球。

现在的空气不是很新鲜，天也不是那样湛蓝。这是为什么？因为有很多人乱砍滥伐，还污染河流。我们在森林里看不见小动物玩耍，也看不见小鱼在水里游泳。

如果长时间都是这个景象，世界末日就会来临。

那么，我们怎样才能保护环境呢？让我来给大家一些建议吧。

首先，我们可以植树。树木可以给予我们新鲜的空气，还可以吸收二氧化碳。

其次，我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气，它对我们的身体没有好处，对地球也没有好处。

这就是我的建议。

今天是世界环境日，让我们一起保护环境，善待地球吧！

With the improvement of living conditions, more and more people can live

longer. However, many old people always suffer from loneliness, which is one of

the major problems in today’s society. To make the old people live better, some

good advice must be followed. Firstly, the young should spare more time to talk

and communicate with their parents, so as to relieve their loneliness. Secondly,

the old ought to understand the work pressure and family burden of the young.

Furthermore, the society are supposed to organize more activities for the old,

so that they can make more friends and have more joys and happiness in their

life.

Friendship is a kind of human relations. It is a human instinct to make friends.When in trouble, we

need friends to offer us help, support and encouragement. With success achieved, we also need friends to share our joys.

Friendship is also one of the greatest pleasures that we can enjoy. It implies loyalty, cordiality, sympathy, affection,and readiness to help. No man can make the most of his life without carefully and conscientiously striving to win the right kind of friends as he goes along.

Knowing how valuable friendship is, we should be very careful in making friends. Real friends are those who have good character, superior ability and kindness of heart. Real friends can share all our sorrows and double all our joys.While making friends, we should take care to select those who have such fine qualities. Then we should treat our friends with courtesy, be careful not to interfere unreasonably with them,and not to ridicule their proceedings. We should forgive their failures and do our best to help them. In short, when we have established friendship, we ought to cherish and treasure it by means of words and deeds. Only thus, can we develop real friendship and keep the sacred lamp of friendship burning all our life. 关于友谊的英语作文二：

making friends is a skill like many other skills. it improves with practice. if you want to meet people and make friends, you must be willing to take some actions. you must first go where there are people. you won’t make friends staying home alone. join a club or a group. taking with those who like the same things as you do is much easier. or join someone in some activities. many people are nervous when talking to new people. after all meeting strangers means facing the unknown. and it’s human nature to feel a bit uncomfortable about the unknown. most of our fears about dealing with new people come from doubts about ourselves. we imagine other people are judging us of finding us too tall or to short, too this or too that. but don’t forget that they must be feeling the same way. try to accept yourself as you are and try to put the other person at ease. you’ll both feel more comfortable.

try to be self-comfident even if you don’t feel that way. when you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile.

if you see someone you like to speak to, say something . don’t wait for the other person to start a conversation.

just meeting someone new does not mean that you will make friends with that person-friendship is based on mutual liking and “give and take”. it takes time and effort to develop. 关于友谊的英语作文三：

Friendship Friends play an important part in our lives,and although we may take friendship for granted,we often dont clearly understand how we make friends.While we get on well with a number of people,we are usually friends with only a very few----for example,the average among students is about 6 per person.In all the cases of friendly relationships,two people like one another and enjoy being together.but beyond that,the degree of intimacy between them and the reasons for the shared interests vary enormously.As we get to know people we take into account things like age,race ,economic conditions,social position,and intelligence.Although these factors are not of prime importance,it is more difficult to get on with people when there is a marked difference in age and background.

Some friendly relationships can be kept on argument and discussion,but it is usual for close friends to have similar ideas and beliefs,to have attitudes and interests in commen ---they often talk about being on the same wavelength .it generally takes time to reach this point.And the more intimately involved people become,the more they rely on one another .people want to do friends favours and hate to break a promise.Equally,friends have to learn to put up with annoying habits and try to tolerate differencesof opinion.wWw.xiNgkoo.coMIn contrast with marriage ,there are no friendship ceremonies to strengthen the association between two persons.But the supporting and understanding of each other that results from shared experiences and emotions does seem to a powerful bond ,which can overcome differences in background ,and break down barriers of age, class or race. 关于友谊的英语作文四：

Friendship is priceless, is not buy friendship, and when you give up your friendship who, you need his help, he can not help you, even if you can not buy with thousands of gold back.

I am a heavy feeling of people, sense of obligation, so there are a lot of friends, such as: "Tang Tao, Zhou Jie, Liu Longyu, Liu Fan, off field ... ... my good friend, are infinite in number, no one told me they After a wonderful childhood, with these friends, my childhood full of joy.

我相信每个学生都盼着周末，我也如此。可是，每到周末我的事情特多，作业一大堆要完成，还想好好复习一番。

I believe that all students are looking forward to the weekend, I so. However, every weekend I thing of Trinidad and Tobago, work a lot to complete, also want to review a.

电视剧童话剧在吸引着我，我忙里偷闲忍不住要看一看。这就让爸爸妈妈十分不满，他们责怪我道：“都长这么大了还管不住自己，你难道不为你的前途考虑吗?你能不让爸妈为你操心吗?你这么大了还不懂事吗?初二不努力会落后的，你老看电视剧行吗?”

TV drama Fairy Tale Drama attracted me, I could not help but want to sneak a look. This let mom and dad very dissatisfied, they blame me: "is so big now also cannot manage yourself, dont you for your future? You can let parents worried about you? Youre old enough to understand? The second day dont work hard will fall behind, you always watch TV play for?"

爸妈的唠叨话一大堆，我听得耳朵都快要起茧子了，我有时冲着他们发火，我不愿听你们唠叨了，以后你们要是再唠叨的话，我就再也不学习了!

Parents nagging words a lot, I hear the ears are going to be heard, and sometimes I shouted at them to get angry, I dont want to hear your nagging, nagging words after you if again, Ill never learn!

这个时候，妈妈无奈的摇摇头，说这孩子我是没法管你了，你愿怎么就怎么去吧!学知识是你的事情，学不好你将会一事无成，学好你会飞黄腾达，由你吧!

This time, my mother reluctantly shook his head, said that the child I cant control you, you like how on how to! Knowledge is your thing, the school is not good you will be without a single success, learn and you will be successful in ones official career, by you!

唉!我怎么不知道要好好学习呢，只不过有时想调剂一下头脑，偶尔看一看电视剧，看一看新闻，这也不为过吧!

Oh! I do not know how to Study hard, but sometimes want to adjust your mind, occasionally see a watch TV, watch the news, this is not excessive!

爸爸妈妈，以后你们不要再唠叨了，我的学习我会安排好的，你们放心吧!

Mom and Dad, after you stop nagging, my study and Ill arrange it, you can rest assured!

My father is a hardworking man and he is very kind.I love him very much.Every morning he gets up earlyto makeus breakfast. In the evening, he is alwayscome back home late. At weekends, he oftengoes outwith me and my mother for fun. He is a man of few words, but he often says to me "A little learning is a dangerous thing". I will always remember hiswords.

Since we went to school, we have been educated to be polite, no matter to

the young or old people. People follow the manner rules and have a nice

communication between each other, but some people ignore the rules and they

treat their rude behaviors as something cool. Today, people advocate the

individuality, so the young generation wants to do something different and catch

peoples attention. For example, they dont care other peoples feeling and

criticize others as they like, or just interrupt when other people is talking,

they just show what they want to say and they believe they are special and cool.

This is very rude behavior that they dont respect others and have the wrong

idea about individuality. We can do something special on the base of respect

others and follow the rules, or we are just the rude people.

每一个人都拥有一颗心：能路见不平、拔刀相助的人，拥有一颗正义的心;能宽恕他人所犯错误的人，拥有一颗宽容的心;对于每一件事都要斤斤计较的人，拥有一颗狭隘的心……在生活中，形形色色的心随处可见。

在饭堂中，我们常能看见身上挂着“青年志愿者”红色绶带的同学。他们每天中午都早早地来到饭堂，抛开一切饥饿和劳累，全心全意地投入秩序维持的工作之中。遇到困难，他们坚持;遭到批评，他们忍受。他们任劳任怨，默默无闻地为我们服务，因此拥有一颗乐于助人的心。

在街道上，偶尔会因为不小心碰到别人，我们都会以一句简单的话表示歉意，这是最平常不过的。而有一些人却要小题大做。他们为了向路人夸大地表达出自己的“委屈”，当场“教训”别人。即使别人不停地弯腰道歉，也不肯善罢甘休。路人都停下脚步，用期待的眼神望着他，希望能够相互谅解。双方的脸都通红通红，他还是咬住不放。因此他们拥有一颗狭隘的心。

在生活中，我们常常会遇到一些好胜心强又容易妒嫉别人的人。当别人某件事情比自己做得更好，他们心中十分羡慕，又十分仇恨地注视他人的成就。因此他们拥有一颗妒嫉的心。

拥有一颗乐于助人的友善之心，上天将给予他们的是赞美的声音;拥有一颗丑恶的卑鄙之心，上天会给予他们的是惩罚的恶果。

Many traditional arts are losing nowadays, because some of them have been

replaced by the new machines and the scientific products. I feel so sorry about

the losing arts, in my opinion, they are so classic and their charm will never

fade away. Take my grandma for example. She is good at paper-cut which was

inherited from her mother. But when comes to my mother’s generation, paper-cut

seems to be kicked out, there are less people need it, so my mother doesn’t

learn this skill. The paper-cut art is losing in my family. When I found my

grandma had this skill, I was so surprised and curious about it. I asked my

grandma to teach me this skill. During the process, I found this art was so

great, I was attracted by it. Some traditional arts like paper-cup should be

kept.

Beautiful outlook indeed attracts people’s attention, if people have the beautiful outlook, of course they will give people deep impression, just like the saying that everyone has the mind of appreciating beauty.

But we must figure out the fact that outlook can’t decide everything, only the ability can do it.

The good example is Mariah Sharapova, she is a famous tennis player. Early in her career, people noticed her beautiful outlook, but more and more beautiful female tennis players come into being, only Mariah gets famous all the time, the reason is that she is outstanding amongst these girls.

She has won so many championships, which makes her the most attractive girl.

Beautiful outlook opens a door for people, but only the ability makes them standing all the time. People will get the genius respect for their hard working instead of their attractive faces.

美丽的外貌确实吸引人们的注意，如果人们拥有好看的外表，理所当然能给人留下深刻的印象，就如有句话说爱美之心，人皆有之。但是我们必须弄清楚外表并不能决定一切，只有能力才能决定一切。

玛利亚莎拉波娃就是最好的例子，她是一位出名的网球运动员。在她早期的职业生涯中，人们注意到了她的美丽外表，但是随后越来越多美丽的女子网球选手出现，而只有玛利亚一直有名气，原因在于她是这些女孩当中最出色的。

她赢得了很多的冠军，这让她最吸引人们的注意。

美丽的外表对于人们来说只是打开了一扇门，但是只有实力才能让她们一直出众。人们会因为他们的努力而得到尊重，不是因为他们吸引人的外貌。

Dear Tim,

With Spring Festival drawing near, I’d like to invite you to my home to experience the festival.

When you come, we can enjoy traditional Chinese food together, and then put up Spring Festival couplets. As a traditional custom, the couplets are always posted on the door of a house. Written on red paper, a couplet is composed of two lines of poetry, which rhyme with each other. Not only do the couplets add some joyous atmosphere to the festival, but also they express people’s wishes for a better life.

I would appreciate it if you could accept my invitation. Looking forward to your coming.

Yours,

Once， when I was a teenager， my father and I were standing in line to buy tickets for the circus. Finally， there was only one family between us and the ticket counter.

This family made a big impression on me. There were eight children， all probably under the age of 12. You could tell they didnt have a lot of money.

Their clothes were not expensive， but they were clean. The children were well-behaved， all of them standing in line， two-by-two behind their parents， holding hands. They were excitedly jabbering about the clowns， elephants， and other acts they would see that night.

One could sense they had never been to the circus before. It promised to be a highlight of their young lives. The father and mother were at the head of the pack， standing proud as could be.

The mother was holding her husbands hand， looking up at him as if to say， "Youre my knight in shining armor."

He was smiling and basking in pride， looking back at her as if to reply， "You got that right."

The ticket lady asked the father how many tickets he wanted. He proudly responded， "Please let me buy eight childrens tickets and two adult tickets so I can take my family to the circus."

The ticket lady quoted the price. The mans wife let go of his hand， her head dropped， and his lip began to quiver. The father leaned a little closer and asked， "How much did you say?"

The ticket lady again quoted the price. The man didnt have enough money.

How was he supposed to turn and tell his eight kids that he didn‘t have enough money to take them to the circus? Seeing what was going on， my dad put his hand in his pocket， pulled out a $20 bill and dropped it on the ground. (We were not wealthy in any sense of the word!)

星斗满天，皓月朗照神州大地。是夜，我梦见了我的祖国——中国

我梦见了中国，科技的曙光源于这里，四大发明震撼古今。

蔡氏少年梦想中国人都能用上洁白无瑕的纸张，他闭门绝宾，暴体田野，终得“蔡侯纸”。文化以其为载体促进着中国的繁荣和进步。毕氏少年梦想中国人都能读上精妙绝伦的书，他韦编三绝，废寝忘食，终得活字印刷术。为我国文化经济的发展开辟了广阔的道路。火药、指南针亦是凝聚了中国少年的梦想而诞生的。我梦见了他们，一群胸怀大志的中国少年。祖国梦见了他们，中国少年的科技梦成就了中华五千年的辉煌。

我梦见了中国，人性的光芒源于这里，中华美德源远流长。

“臣心一片磁针石，不指南方不肯休”文天祥以身许国;“收拾旧山河，朝天阙”岳飞精忠报国;“生平未报国，留作忠魂补”杨继盛以身殉国;他们悲壮的故事是中华传统美德中最闪耀的部分，爱国是每个中国少年最初的梦想，它流淌在每个中国少年的血液里。我们梦见了他们，一群义薄云天的中国少年。祖国梦见了他们，中国少年的人性梦成就了中华五千年的美德。

我又梦见了中国，充满希望的未来源于这里。蔡伦、毕升、文天祥，他们都是老一代的中国少年，而今的我们才是肩负着中华民族伟大复兴重任的新中国少年。

少年智则国智。作为新一代的中国少年，奥数、英语、文言文我们样样精通，科技、经济、政治我们涉猎广泛。清晨，教室里传出的是我们朗朗的读书声;课间，操场上来回穿梭的是我们矫健的身姿;夜晚，实验室里映入眼帘的是我们挑灯夜战的灯光。因为我们是中国的希望。

少年强则国强。遭受过地震、雪灾、瘟疫、泥石流的我们并没有畏惧过灾难，一方有难八方支援，一个中国少年的身后是千千万万的中国少年。我们勤劳勇敢，自强不息，因为我们是中国的希望。

是夜，我梦见了中华民族的伟大复兴。这不仅仅只是我一个人的梦，这是中国少年的梦。一个梦亦是一种责任，故今日之责任，不在他人，而全在我少年。少年智则国智，少年强则国强，少年梦，中国梦!

Buying Vegetables

This morning I got up early and went to the market to buy some vegetables instead my mother for the first time.

The market was very crowded and busy with nearly all kinds of goods on display. Some sellers were shouting at the top of their voice to attract the attention of the people. Housewives were picking out vegetables and bargaining with the sellers. A man was selling fresh fish, which were swimming in a big basin, and a lot of buyers crowded around it and chose what they wanted. One fruit seller, standing behind piles of fresh fruit, greeted me Warmly, trying to persuade me to buy some. He felt a little disappointed when I shook my head.

What a busy and noisy market! (128 words)

Yesterday, my parents were not home. And I had to stay at home by myself for one day and one night. I was very happy at first, because there wouldnt be anyone criticizes my behavior. I can do whatever I want. But later I felt desperate. There was nobody cook for me, asked me to do things or criticized me. I felt empty and desperate as the house is only me. When the night fell, I was afraid. The computer games or the cartoons couldn’t attract my attention. I hate living alone.

昨天，我的父母不在家。我得自己一个人呆上一天一夜。我一开始很开心，因为没人会批评我的行为了。我可以做任何我想做的事。但后来我感到很郁闷。没人给我做饭，没人叫我做事情也没有人批评我。整个房子只有我一个人，我感到很空虚和郁闷。当夜幕降临的时候，我就开始很害怕了。电脑游戏或动画片都无法吸引我的注意。我讨厌一个人生活。

桑德斯上校退休后拥有的所有财产只是一家靠在高速公路旁的小饭店。饭店虽小，但颇具特色，与众不同。可最受欢迎的、也是客人最爱吃的一道菜就是他发明烹制的香酥可口的炸鸡，仅此就给他带来了一笔可观的财富。多年来，他的客人一直对他烹制的炸鸡赞赏有加。可是令他万万没想到的是，由于高速公路改道别处，饭店的生意突然间也一落千丈，最后只好关门歇业。被逼无奈，桑德斯上校决定向其他饭店出售他制作炸鸡的配方，以换取微薄的回报。

在推销的过程中，没有一家饭店愿意购买他的配方，并且还不时地嘲笑他。一个人在任何年龄被人嘲笑都不是件令人愉快的事，更何况到了退休的年龄还被人嘲笑，这就更令人难以接受了。而这恰恰发生在了桑德斯上校身上。他不但被人嘲笑并且接连不断地被人拒绝，可见这些经历对他的影响有多么巨大。但他始终没有放弃，在没有找到买主之前，他开着车走遍了全国，吃住都在车上，就在被别人拒绝了1009次后，才有人终于同意采纳他的想法，购买他的配方。从此后他的连锁店遍布全世界;也被载入了商业史册。这就是肯德基的由来。

人们为了纪念这位桑德斯上校，就在所有的肯德基店前树立一尊他的塑像，以此作为肯德基的形象品牌。俗话说：“神枪手是一枪一枪打出来的!”缺乏坚持不懈的毅力或者认为自己不能得到自己想要的东西，这两者都是阻碍大多数人勇于改变的关键原因。如果你能够紧紧抓住自己的目标不放并坚持不懈，那么很快你就会超过大多数人。记住，是你掌握着自己的生活。如果你一心想达到一个目标，就一定会有办法取得成功。
