篇二：英语作文-friend朋友

On Making Friends

As a human being, one can hardly do without a friend, for life without friends will be a lonely voyage in the vast dark sea or one in the barren desert. Traly, a friend gives out light and warmth like a lamp. For this reason, I have always felt it a blessing if a friend comes to console me in my sadness, cheer me up in my low spirits, or heartedly share with me my happiness. It is wonderful, too, to feel that someone is standing by me and ready to provide help and encouragement in my pursuit of a noble and glorious cause.

For millions of years, people have heaped beautiful verses and essays upon friendship. Yet, they, too, have mercilessly accused false friendship, for there are always some mean characters who approach you and act as dear friends when you are wealthy or influential, but desert or even betray you the instant you come down in the world or are entrapped by unfortunate things. Therefore, people all attach great importance to the recognition of true friendship. And a faithful friend is considered even more precious than a priceless pearl or a precious stone. The old saying "A friend in need is a friend indeed" has become the teaching and standard for true friends.

Still, it is natural that different people observe different principles in making friends. Some view it important to make friends with whom they may share similar interests or hobbies with. Others are liable to befriend VIPs so as to gain some favors or privileges. And I am of those who think very little of similarity or position or power. So long as a person has a heart of gold, being warm-hearted, selfless, honest, open-minded, but not brutal, cold, shortsighted nor narrow~minded, I am willing to make friends with him or her, give my due support and help, and remain faithful to him or her all my life.

关于朋友的英语作文理想的朋友

An Ideal Friend

Friends can be classified into two kinds, good friends and evil friends. Evil friends lead us astray and may destroy our life, while good ones drive us towards the right and make our life successful.

Two of them exist in our daily life. However, ideal friends exist in people's mind. They should be diligent, successful and loyal. When you need help, they will stand beside you and be delighted to give you a hand. Also you can share your happiness and sorrow together.

In my opinion, friends can share something but they also should keep their own secrets. So I wish my friends wouldn't interfere in my privacy too much. On the other hand, my friends should have Something in common with me, at the same time something special. In this way we can attract each other and learn from each other.

作文翻译:理想的明友

朋友可以分为两种，益友和狐朋狗友。狐朋狗友会使我们误入歧途，毁了我们的一生；而益友会使我们明辨是非，使我们成功。

日常生活中这两种朋友都存在。然而，在人们心目中仍存在理想的朋友。这种朋友勤奋、成功并忠诚。当你需要帮助时，他们会与你并肩作战，伸出援助之手。他们还可以与你分享快乐与痛苦。

我认为朋友要分享一些东西但也要保留自己的秘密，所以我希望我的朋友不会过多地介入我的私事。从另一方面来说，我的朋友和我应有共同之处，同时又有各自的特点。这样我们才可以互相吸引，互相学习。

My Ideal Friend

Friend is better than fortune。 Friend also is worse than poison in some cases。 The above two statements are opposite and seem to be unreasonable but they can be explained as follows： the latter implys all evil friends who lead us go astray; the former implys all good friends who drive us towards right。

My ideal friend is of course a good friend whose goodness is shown below： He has no bad likings， as smoking or drinking。 He lives in frugality。 He studies diligently so as not to waste his golden time。 At home he honors his parents and loves his siblings; at school he venerates his teachers and sympathizes with his schoolmates。 In a word， he has all the good characters better than

mine。 I can follow him as a model。 By his perceptions I am persuaded to go the right way。 By his warnings I am aware of the danger of taking a wrong action。 By his helps I am free from all difficulties。Indeed， if I have such person as my friend， I shall never fear difficulty and I shall never know the existence of the word “failure”。

In our life we come across many people,and of them we like some. People we like,we consider them as friends. Dictionary defines friend as “A person whom ones knows, likes and trusts.” There are three kinds of friends: friends whom we meet and see only at school, friends whom we loose as we grow, and best friends who are there for us no matter what kind of situation we are in.

Frist, friends we see and meet only at school. We might have known them for a long time, but the most we must have spoken to them about is their names and what classes they are taking. These school friends are nice to talk, but never to do anything more than that. If we happen to see them out of school we act like we don’t even know them. At most we will throw a smile at each other. When we leave school, few of them can stay in touch with us, they disappeared just as we hadn’t known them.

Second, the friends we have known once upon a time, who will bing back memories of those days. When we are together with those friends, we do anything to have a good time and a good laugh. The most we talk about is school, work,weekend,funny things and some parts of our life, but never our personal life and our feelings. We have fun together most of the time and we don’t mind seeing and hanging out with others out of school. These friends are better than friends in school, but they can help us nothing when we get in troubles.

Final, our best friends, who are there for us all the time and try to help us out of even our deepest troubles. These friends are always ready to apare their time, joys and sorrows, may it be ours or theirs,and even their lives for us. They have seen us tears, embarrassed us, have been mean to us, they are important in our life, these friends are whom we can truly trust. We can’t live alone without these friends, when we possess of these friends, we have the world.

Our life is connected with others around us, so friends are together with us through our life. A person who don’t have any friend,his life must be miserable. We have a lot bowing acquaintances, and we just some best friends we can count on them.

From thousands years ago to today, friendships always exist. People also like to talk about what is the true friendship. Though thousand years have gone, there are different views on what is the true friendship.

There I also want to show my point. Maybe because of my laziness, I often sit on grassland to think some unreal things. So I have had my own understanding of friendship. Of course, my understanding is totally based on single boys.

To me, friends can be divided into three kinds. First is ordinary friend, and then is deep friends, and the most reliable is brothers.

In my own opinion, everyone we know can be our friends. Because they can help us when helping us doesn’t holdback them. Also we will help them when we can. But these ordinary friends won’t help you when it can make them into trouble. They can’t be relied on.

And what are true friends? True friends are who you can believe. Whenever you ask them for help, they’ll help you; whenever you need somebody to talk, they’ll listen to you; whenever you misunderstand them for something, they’ll forgive you. Anyway they’ll be on your side whenever you need them.

Brothers are the most reliable people. They keep an eye on you. When you need help, they’ll come to help without your asking. Actually I can’t express the idea exactly. But as brothers, they will laugh with you, weep with you, even crime with you if it is good to you. Maybe someone think these so-called brothers are wrong to crime to help. However this may let us know the brothers.

There is no doubt that everyone has friends and everyone can be our friends .Take our parents as an example ,they also can be our friends if they talk with us ,share secret with us and are equal to us .

It is indisputable that friends are very important to us .The reasons are in the

following .First ,friends can help us to solve the problem if we haven't the ability to deal with it by ourselves.Second ,we can share happy and sorrow with our friends so that we will not feel lonely any more .Third ,friends will encourage us when we have no confidence ,moreover ,they will persuade us when we do something wrong.

As we all know ,the more friends we make ,the happier we will be.Friends will bring about profound impacts on our life who suffer when you suffer and laugh when you laugh .As a result ,we should treasure our friendship

A good friend is someone who can share our happiness and sadness , who would feel happy with us when we have some achievements or someone who would go though fire and water to help us when we get into trouble , a person that will be our side whenever we need him . A good friend is a person who can give his shoulder to let us lean again until our tears run dry . A friend is a person with whom I maybe sincere , with him , I may think aloud . Yes , Life is not a bed of roses . It is full of ups and downs , turns and twists . We can't be able to predict or guess what will happen to us .

You may come across an accident without warning . If such is the case , you have got to go to hospital . If you are rich enough , you may tide over it by yourself . But if not , you have to turn to

篇四：英语作文(关于朋友)

My Friend

Everyone needs friendship. No one can sail the ocean of life single handed. We need help from, and also give help to, others. In the modern age, people attach more importance to relations and connections. A man of charisma has many friends. His power lies in his ability to give.

My best friend is my college classmate who is a humorous boy. He is also my deskmate .I did not notice he is a boy who is friendly and easy to get along with until he became my deskmate .OK,I must admit that I judge a book by its cover!

Although he isn’t handsome,he is a good man . I am a bad-tempered girl,but he is very gentleman ,and that is the reason why we never argued with each other .

Now we live in different cities and different universities.But that’s not the problem ,we still keep in touch .Of course ,distance can’t make our friendship weak! We often talk with each other about some interesting stories and our troubles by telephone or QQ. I am very happy to have such a friend like him!!

However ,not all people have good temper like him,and he is the only one among my friends that I meet.For example,my college roommates are a group of special girls.My administrator of the dormitory is a very goodness girl. She is also my first friend since I

entered university. When I feel lonely ,she always stays with me,which makes me so move.As life is full of strike and conflict, we need friends to support and help as out of difficulties. Our friends give us warnings against danger. True friends share not only joy but, more often than not, they share sorrow. There is a girl who is very enthusiastic to help others in my dormitory ,if you have troubles,she will try her best to help you whenever and wherever .there are also some girls ,they are a little introverted,so you never know how they think ,sometimes, when you say some words which you believe is normal,but they will really care about that,such things make me feel embarrassed. But there are more laughter when we are together in free time.

So it’s very important for everyone to handle with the friendship ,everyone has his own personality ,sometimes quarrel is normal,we should learn to forgive others,which is also a goodness. After all, friendship makes our life happy and harmonious.To many of my friends, I know what to treasure, what to tolerate and what to share, I will never forget my old friends and keep making new friends. The more friends you have, the more happiness you will possess.

我的朋友

朋友对每个人都是不可或缺的，当然，我也是。

我最好的朋友是我的一位高中同学，他是一个很风趣的男生，他曾经是我的同桌，在他成为我的同桌之前我曾经以为他是不好相处的一个人。好吧，我承认我以貌取人了。

虽然他长得不帅，但是他是一个很好的人。我是一个脾气暴躁的女生，但是他非常绅士， 不会针锋相对，这应该是我们从来没有吵过架的原因吧。

所以虽然我们现在在不同的地方上大学，我们也经常联系。距离当然不会使我们的关系变淡了。我们经常在电话或者扣扣上谈谈彼此在生活中发生的事情。

当然并不是所有人都有他那样的好脾气，至少我活了快20年只碰到了一个这样的人。所以，比如我的大学舍友就是一群性格迥异的女孩。

我们的舍长是一位善良的女孩，她是我在大学的第一个朋友。当我被其他人孤立的时候，只有舍长一直陪着我，这让我非常的感动。所以说，当你遇到困难的时候，朋友的帮助非常重要，他们帮助你度过困境，一起更好的走下去。

还有一位女生非常热衷于帮助别人，如果你有什么困难，她肯定是第一个冲上去帮你解决问题。还有其他人，有的性格比较内向，你永远不知道她们在想什么，有时候你不小心说错一句话，做错一件事，她们就生气好久。搞得宿舍的气氛很尴尬。但是更多的时候，我们在一起还是充满了欢声笑语。

所以说学会处理好朋友之间的关系也是非常重要的。每个人有不同的性格，在一起当然会有冲突有分歧，所以，处理好关系也是一种能力。

我希望我和我的朋友们能一直像现在这样，就算相隔很远，也能时常联系。不因时间或空间的改变而疏远。愿我们友谊常在。

篇五：关于朋友的英语作文
