高二英语作文：何如维持友谊(经典20篇)

In many countries in the world, women are looked down upon. It is more

difficult for them to get some work than men. In order to get a job, they

sometimes have to tell a lie. Thats unfair. In fact, women can work no worse

than men. Theres nothing that women cant do.

Perhaps, they are better at their work than men. For example, in making

telephones and computers, many companies would rather employ women, for men

cant pick up the small pieces with their fingers. Like , they can also become

excellent engineers, doctors and teachers. So I am sure the day will come soon

when women can really get equal rights.

When we are small, the teacher told us that we should help others, offering help to someone who is in need of help is Chinese tradition. Today, we see people give their hands to the old and the weak, we are happy to see that, but some negative examples exist at the same time. It has been reported that a woman was jumping off a bridge, many people saw it, but they just took out their cellphones and took the picture, no one tried to stop the woman. It is so angry that people become so cold blooded, they just like the murders. We need to offer people help, but we must take care of our security, or we not only fail to rescue people, but also lose our lives. Saving people sometimes needs to use wisdom, if we can persuade them from killing themselves, we are successful in stopping the tragedy.

当我们还小的时候，老师告诉我们应该要帮助他人，帮助那些需要帮助的人是中国的传统。今天，我们看到人们给予老人和弱者帮助，我们很高兴看到这些，但是同时一些不好的例子也存在着。据报道，有一个女人正想要跳下桥，很多人围观，但是他们只是拿出手机来拍照片，没有人想要阻止这个女人。人们变得这么冷血，多么令人生气啊，他们就如凶手。我们需要给人提供帮助，但是我们也要注意自身的安全，不然不仅不能救人，还会丢掉自身的性命。救人有时候是需要智慧的，如果我们能劝服别人不自杀，就成功地阻止了悲剧的发生。

Freedom in my Dream As the whole world has its boundaries, limits and

freedom coexist in our life. I don’t expect complete freedom, which is

impossible. I simply have a dream that supports my life.I dream that one day, I

could escape from the deep sea of thick schoolbooks and lead my own life. With

my favorite fictions, I lie freely on the green grass, smelling the spring,

listening to the wind singing, breathing the fresh and cool air and dissolve my

soul in nature at last. Simple and short enjoyment can bring me great

satisfaction.I dream that one day the adults could throw their prejudice of

comic and cartoon away. They could keep a lovely heart that can share sorrow and

happiness with us while watching cartoon or doing personal things. That’s the

real communication of heart to heart. I have the belief that my dreams should

come true. I am looking forward to some day coming when I am like a proud eagle,

which flies to the blue and vast sky.

As the world gets globalized, the communication between countries has been enhanced, studying abroad has become a dream for countless young students. As a college student who is majoring in English, I would like to keep my further study in a foreign county after graduation, so that I can improve my knowledge and my ability to live.

随着世界变得全球化，国家间的交流得到了加强，出国学习已经成为了无数青少年的梦想。作为一名学习英语专业的学生来说，我喜欢毕业后出国学习，这样我就可以提高我的知识和生活的能力。

As for me, learning English in a native speaking environment is very important. I would choose to continue my further study in Britain orAmerica, both are good for my major. The English-speaking countries can provide me a good chance for me to gain my knowledge. I can know more about the culture and conventions, it helps me to do some translation work.

对于我来说，在一个讲本土语言的国家学习英语很重要。我会选择在英语或者美国继续我的学业，这两个国家都对我的专业有好处。讲英语的国家能给我提供学习知识的好机会。我可以学到更多的文化和习俗，这有助于我做一些翻译方面的工作。

Overseas study would also provide a good opportunity to learn how to live by myself. In china, I have been living with my parents all my life, my mother takes care of me all the time, but now, I am an adult, it is time for me to be independent. I can learn how to communicate with others, how to take care of myself and so on. All these abilities are vital for my future career.

出国学习也能提供一个学习如何独立生活的好机会。在中国，我一直都和父母生活在一起，我的妈妈一直在照顾我，但是现在，我已经是一个成年人了，该是时候自立了。我可以学着如何与人交流，如何照顾自己等待。所有的这些能力对于我将来的职业很重要。

With the constant interaction between nations, it is necessary for us to learn more about the world. Studying abroad provides such chance, at the same time, we could also learn to be independent.

随着国家之间的交流日益频繁，更多的了解世界对我们来说是很必要地。出国留学提供了这样的机会，同时，我们也能学着自立。

导语：在日常生活中，如果我们跟朋友相处融洽，我们的心情也会更加愉悦。下面是yuwenmi小编为大家整理的英语作文，欢迎阅读与借鉴，谢谢!

In our daily life, if we get on harmoniously with our friends, we’ll feel more joyous. But we’ll feel lonely without friends.When our friends feel upset or get ill, we shouldn’t ignore them or look down upon them. On the contrary, we ought to calm them down, show our love and concern to them and try our best to help them overcome the hardships. Sometimes we may have some misunderstandings or disagreements with our friends, thus we had better have a discussion with them and try to accept their good ideas instead of quarreling with them. As long as we can follow these good suggestions, we’ll find it easy to make more friends.

【参考译文】

在日常生活中，如果我们跟朋友相处融洽，我们的心情也会更加愉悦。然而若是没有朋友则会觉得孤单。当我们的朋友忧伤或是生病时，我们不应冷落或轻起他们，相反地，我们要帮他们平抚心情，尽自己最大的努力关心他，帮助他渡过难关。有时候我们会与朋友产生误会，发生分歧，这时我们最好是跟朋友好好谈谈而不要争吵，尽量理解他的好的想法。只要我们遵循这些建议，我们会发现想要结交更多的朋友很简单。

Environmental problems are as big as not for individual country or individual people to address. In other word, we have reached the stage that environmental problems be solved for international view. To what extent do you agree or disagree?

In recent years, many nations have become more aware of the environmental issues each nation faces, such as air and water pollution. The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of becoming an international problem needing international cooperation to resolve.

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology. By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed. Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole.

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection. In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international commission elected by the participating nations of the world. All members must agree to abide by the standards established.

The environmental issues facing each country are not unrelated to the well being of the rest of the world. The impact is long term and international in scope. Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc., the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems.

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment. Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment.

没有友谊，那个人的生活便会枯燥无味，没有丝毫的乐趣；在那个人的身边没有欢声笑语，他的生活将是平平淡淡。可见，一个人与另外一个人的友谊是多么的重要呀！可是，我这位“多嘴大王”因这张嘴吧，可让我差一丁点就掉进了万丈深渊。那时候，悔恨的泪花儿一定会从我的眼睛里夺眶而出。

如果时光可以倒流，我真想回到大上个星期天，想一想，我与刘政谁对谁错。那一天，我正从刘政和刘志丹的位置前路过，看见刘政用馒头般的拳头砸向孔壮。这时，我想告诉老师，可是一想，我与他那好关系，开始我又左右为难了。这时，我觉得有两条路可选择：一就是告诉老师，可是我不忍心那么做，因为我不想让老师把我兄弟海“K”一顿。二不告诉老师，让他胡作非为，就把自己当成旁观者没看见，可是不行，因为我不想看到让兄弟这么狂妄。最终，我选择告诉了老师。

当老师来把他叫走时，他狠狠地瞪了我一眼。我知道刘政是在发自内心的恨我。此时此刻，我突然觉得自己是一个忘恩负义的小人，我也十分内疚。回想起往日的哥俩，是怎样的互相帮助互相爱护的，想想今天的举动，是多么的令人“可恨”。可是，我觉得自己永远是对的，就算我们两个再好，一旦发现他有什么不可以的行动，一定要及时告诉老师，否则，他日久成疾。

另外，我还有个好朋友名字叫马列。我们的关系是谁也比不上的，同吃同住。可是，他的缺点就是文学方面不太好，还有在字体上，不过呢，他的体育成绩在班里是独一无二的，就凭他那肌肉和奔跑的时候吧。呵！那肌肉块，呀，真是怎样形容呢？奔跑时，简直是象一匹横冲千山万水的骏马。我们俩无论是什么困难，都会迈着矫健的步伐，永不停息停息……

友谊是伟大神圣的，在我的身边有好多好多的朋友，我们之间的友谊不容许任何人来破坏；不允许任何人来……

近来，越来越多的高校已经意识到了创建绿色校园的重要意义，它已成为一个遍及全国的新趋势。

Recently, more and more colleges and universities have realized the significance of creating a green campus, it has become a new trend of the spread.

那么，是什么意思时，我们指的绿色校园?一方面，对环境的保护是必要的，不可否认，这是这一概念的前提。另一方面，它是远远不够的，以满足绿色校园的总体目标简单地保持绿色的环境。相反，它也需要所有的工作人员和我们共同的努力，学生的积极的文化氛围建设。

So, what does it mean when we refer to the green, the campus? On the one hand, the protection of the environment is necessary, it can not be denied, this is the premise of this concept. On the other hand, it is far from enough, in order to meet the overall goals of green campus simply keep the green environment. On the contrary, it also requires all staff and our common efforts, the students active cultural atmosphere construction.

因此，为了创造绿色校园，第一，它是必要的，每个人都认为我们自己主办的校园，并认识到绿色的启示给我们带来了房子。更重要的是，需要采取行动以实现目标。最后但并非最不重要的，我们可以传播的精神，更广阔的领域，呼吁更多的人加入这个项目的前景。

Therefore, in order to create a green campus, the first, it is necessary, everyone thinks of themselves as the host of our campus, and to realize the green enlightenment brought the house for us. More importantly, the need to take action to achieve the target. Last but not least, we can spread the spirit, a wider area, call for more people to join the projects prospects.

在这一则报导中，我学到很多事，但我第一个想到的是，造成地球变暖的原因是二氧化碳增加。

In this paper, I have learned a lot of things, but I think the first one is the cause of global warming, the increase of carbon dioxide.

为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决，说不定可以改善地球继续暖化，例如：目的地很近的话可以骑自行车;目的地很远的话，可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

Why carbon dioxide will increase? I think the reason is often drive, raising livestock, food factory emissions of smoke...... Etc.. But these are all can solve them together, it can improve the Earth continues to warm, for example: the destination is close enough to ride a bike; destination long enough, can take the public transport; waste livestock treated and then discharged into the Hanoi factory; to build a waste treatment plant...... Etc..

请大家不要小看二氧化碳的威力，等到海平面上升、都市浸水和农地淹没，到最后就会面临粮食不足的危机了。请大家跟我一起喊：“停止伤害地球的行为吧!我们居住的地球只有一个。”

Please do not underestimate the power of carbon dioxide, when the sea level rise, urban water and farmland submerged, eventually facing food shortage. Please call with me: "stop the harm to the earths behavior! Only one earth on which we live. "

I always think there is not enough time. For example， I have just taken a

three-day holiday. But when I look back， I just feel that it‘s only one day.

There goes a proverb， “Time is money”。 Now I want to say， time is more precious

than money， because when money is spent， we can earn some more again. However，

when time is gone or lost， never will it return.

Time goes without being noticed. The time for our study and work is usually

limited. So I think we must make full use of our time. But it‘s a pity that I am

always not aware of the importance of time until it’s too late.

So I think， I should get into the good habit of saving time because wasting

time is equal to wasting one‘s life. Do not put off what can be done today till

tomorrow!

About Friendship

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.

友谊是一种人际关系。交友是人的一种本能。患难之中，我们需要朋友帮助、支持和鼓励。取得了成绩，我们也需要朋友分享欢乐。

友谊又是我们可以享受的最大乐趣之一。友谊蕴含真诚、热忱、怜悯、挚爱和乐于助人之意。在人的一生中，如果不认真谨慎地力求交结正直的朋友，他就不能从生活中获得最大益处。

懂得了友谊是多么宝贵之后，就应谨慎地选择朋友。真正的朋友品性良好，能力上等，心地善良；真正的朋友能分担我们的忧伤，倍增我们的欢乐。交友之 时，要谨慎选择具有这样美好品质的人。然后应以礼待友，当心不要无理地妨碍他们，不嘲笑他们的所作所为。我们应原谅朋友的失败，并尽己所能帮助他们。 简言之，建立了友谊之后，要通过言语和行动来珍惜友谊，像爱护宝物一样爱惜友谊。只有这样，才能发展真正的友谊，让神圣的友谊之灯照亮我们一生。

[描写友谊的英语作文

It seems like a silly question, anyone in sane would give a hand to the elderly who fell. But in China, this question is becoming tricky. Many news report that there are some old people not just fell, they do it on purpose. Usually, they walk on a crowdy street, and pretend to faint or just lay down on the ground, intend to accuse the one who comes to help as a perpetrator and blackmail him/her for the treatment fee. Many people have fell for that and had to pay as there is no witness to prove their innocence. As for these negative news, people is afraid to help those old people in need, that makes some of them who are in real trouble could not get help in time. I once asked one of my friends: “Why the old people turn bad? If you see one in the street, would you help?” He said: “It is not the old people turn bad, it is the bad people turn old. I will video him/her to make a statement first, then decide if I would help.”

这似乎是个愚蠢的问题,任何清醒的人遇到跌倒的老人都会伸出援助之手。但在中国，这个问题变得棘手。很多新闻报道说有些老人不只是跌倒而已，他们是故意这么做的。通常他们会走到人潮涌动的街头，假装晕倒或者是直接躺在地上，想要指控那些来帮助他的人为肇事者，敲诈他们要治疗费。很多人都上当了，由于没有目击者证明他们的清白，他们被迫支付了费用。正因为这些负面新闻，人们害怕去帮助那些需要帮助的老人，也因此造成了那些真正有困难的老人没有得到及时的帮助。我曾经问我一个朋友：“为什么现在的老人变坏了?如果你在街上看到这样的老人你会帮助吗?”他说：“不是老人变坏了，是坏人变老了。我会先录像让他做一个声明，再决定是否帮助他。”

Learning a foreign language is an enriching undertaking. To make the most of your experience, you may need to develop some specialized strategies. Here are some principles to keep in mind.

1. Language is more than a set of grammar rules. Although structural accuracy is an important component of communication, you must also learn how to communicate in a manner that is appropriate to the situation. Likewise, in addition to building a large vocabulary, you will also need to learn ways of paraphrasing so that you will be able to communicate effectively when you don’t know an expression or it has slipped your mind. Body language and gestures are also important communicative strategies.

2. Active language use is far more important than talking about language. The ability to recite the rules of English grammar does not guarantee that you will actually be able to communicate in the language. Spend your time communicating in the language, creating messages, obtaining information, listening for details and so on.

3. Don’t be afraid of making errors. Errors are a natural part of the language learning process and no one can avoid them. Do not let fear of making an error prevent you from communicating. Even if your language ability is not perfect, your message may be understood. Of course, accurate use of language is an appropriate goal of language study.

4. Language learning is a long-time process. Therefore you must have realistic expectations of your performance after one semester, one year, or several years of language learning. Advanced proficiency is often best achieved after long period of practice and residence in a country where the target language is spoken.

5. Be an active language learner. Study models, look for patterns, and make informed guesses, study idioms. If you do not entirely understand a passage, do not ask for a translation immediately. Make use of the language you already know or words that may be related to other words you know. Although language learning can be hard work, your efforts will be rewarded with a deeper understanding of yourself and the global village of which you are a citizen.

学习一门外语是一个丰富的任务。充分利用你的经验,你可能需要开发一些专门的策略。这里有一些原则要牢记。

1。语言不仅仅是一套语法规则。虽然结构精度是通信的一个重要组成部分,你还必须学会如何沟通的方式是适当的。同样,在构建大型词汇表之外,您还需要学习的方法套用,这样你将能够有效沟通当你不知道一个表达式或溜你的头脑。肢体语言和手势也很重要的交际策略。

2。积极的语言使用比谈论语言更为重要。背诵英语语法规则的能力并不能保证你会可以用语言交流。花费你的时间在语言交流,创建信息,获取信息,听细节等等。

3。不要害怕犯错误。错误是语言学习过程的一部分,没有人能避免他们。不要让害怕出错阻止你交流。即使你的语言能力并不完美,你的信息可能会被理解。当然,准确的使用语言是语言学习的一个适当的目标。

4。语言学习是一个长期的过程。因此你必须有现实的期望的性能在一个学期之后,一年或几年的语言学习。先进水平通常是最好的实现经过长期的实践和居住在中国,目标语言是口头的。

5。是一个积极的语言学习者。研究模型,寻找规律,作出明智的猜测,研究习语。如果你不完全理解一段,不要求立即翻译。利用语言的你已经知道或者单词,可能与其他单词你知道的。虽然语言学习是艰苦的工作,你的付出会得到回报,更深入地理解自己和地球村的公民。

Welcome to our school!

The first day for me to go to high school, I felt so excited, because I

came into the new stage of my life. The school asked the students to live in the

dormitory, so I had to move out and left my parents. This was such a big

challenge for me, because I never left home before. I needed to learn to be

independent, what’s more, I also learned to get along with others. High school

was like a little society for me and I handed the problems well. The other

challenge was from study. I had to learn so many subjects and fought for my

future college. I met difficulties and felt frustrated, but I told myself not to

give up and I got over the difficulties. High school life is not easy, but we

grow up quickly.

Some people say that friendship wind, like a cloud, as the years pass, it will slowly fade away.

Others said, the friendship, however, such as the sea, and through the test of time, it will become deeper and more heavy.

Friendship is an intimate friendship, help each other to develop ideas, to success; And give a person with aggravation of hope and strength, add to the warmth of life.

As the growth of the age, I gradually found that interpersonal relationship is very complicated. Whenever meet embarrassing, I always want to a problem: friendship really can forever?

Some people, the mouth moment to say: "for the sake of friendship can sacrifice everything." But quite differ to do and say. He is narrow-minded, once a friend gave him a joke, or where is misunderstood, will be opposite.

True friendship is hard-won, so need more understanding between friends and love, let us common cultivation of the flower of friendship! Irrigation it with pure soul, it with warm sunshine, let the friendship forever.

有人说，友谊如风，如云，随着时光的消磨，它将慢慢淡去。

也有人说，友谊如山，如海，经过时间的考验，它会变得更深，更重。

友谊是亲密的情谊，有助于彼此间开拓思路，走向成功;又给人以排忧解难的希望与力量，增添人生的温暖。

随着年龄的增长，我渐渐的发现，人与人之间的关系十分复杂。每当遇到难堪的事，我总在想一个问题：友谊真的能地久天长吗?

有些人，嘴里时刻在说：“为了友谊可以牺牲一切。”但是做的和说的完全不一至。他心胸狭窄，一旦朋友给他开了个玩笑，或什么地方误会了，便会反目成仇。

真正的友谊是来之不易的，所以更需要朋友间的体谅和爱护，让我们来共同栽培友谊之花吧!用纯洁的心灵灌溉它，用明媚的阳光温暖它，让友谊地久天长。

Human, science and nature, the three phase was quoted rates are inseparable. The wonders of nature, a little thing, through the baptism of the time, and meticulous observation, often can give a person with enlightenment.

Vast forests, sunshine give plants grace, to be able to get the nutrients and thrive. Such as the morning sun open the eyes of animals, everything is ready. Squirrels, squirrel, embarks from the house, looking for full sweet red pine nuts, all kinds of plant seeds and slowly by seeding them to other places. While the weasel feed on smaller herbivores, sable and then ate the weasel... As if people eat the big fish, big fish eat small fish, small fish eat shrimp, shrimp eat plankton, interlocking between RACES, interdependence restricts each other.

Foreign scientists have done an experiment: introduce the sheep in a rare nature reserve, where the bamiyan, natural environment is superior, and there is special personnel to the group of kids to their natural enemies, Wolf, moved to another place. So the sheep started in the breeding. Until grass and low shrubs are eaten, the number of sheep instead of less. Because they live too comfortable, there is no enemy attack, the number that is too carefree life let their constitution also fell. Then the scientists tried to introduce wolves again. The result is in the relationship between predator and prey, good robust species to survive, wolves eat sick defect part. Natural selection and evolution, has been the nature and even the survival of human society the same criteria.

Cut down some trees, is to destroy a part of birds and insects; Killing of bees, small fish, can also cause cannot spread pollen, fish cannot reproduce problem... Sabotaged a part of the food chain, will bring ill-defined disaster. Because in front of the natural fair, each species, each independent individual organisms is so beautiful and full of value.

Because of the diversity of species and colorful nature. Want to live in harmony with her and get the kind of treatment, will be good to nature, to understand the nature, and have good at discovering and innovative mind.

人类、科学、自然，这三者相生相息密不可分。大自然的奇妙之处在于：一件小小的事物，经过时间的洗礼以及细致入微的观察，往往能给人以启示。

广袤的森林中，阳光雨露给予植物恩泽，使其能够得到养料然后茁壮成长。等清晨的阳光掀开动物们的眼睛，一切也准备好了。松鼠、灰鼠从居所里出发，寻找饱满香甜的红松子，各种植物的种子于是慢慢的被他们带到其他的地方落地生根。而此时黄鼠狼以体型较小的草食动物为食，紫貂继而吃掉了黄鼠狼……就好像人吃大鱼，大鱼吃小鱼，小鱼吃虾米，虾米又吃浮游生物一样，各种族之间环环相扣，相互依存相互制约着。

外国的科学家曾做过一个实验：将一种稀有的羊引进自然保护区，那里水草丰美，自然环境优越，并且还有专门的人员为这群天之骄子将她们的天敌——狼，迁往另外的地方。于是羊群开始在此生息繁衍。直到草和低矮的灌木被吃光了，羊群的数量反而越来越少。原来是因为它们生活的太过安逸，没有天敌进犯，数量过于膨胀，太过悠闲的生活让它们的体质也下降了。后来科学家们尝试着再一次引进狼群。结果是在捕食者与猎物的关系中，健壮优良的品种得以存活，狼群则吃掉病弱残疾的部分。物竞天择，优胜劣汰，一直都是自然界乃至人类社会不变的生存准则。

砍掉了某种树林，就等于灭绝了一部分鸟类、昆虫;捕杀蜜蜂、幼小鱼类，也会造成花粉无法传播，鱼群无法繁衍的问题……大肆破坏生物链中的某一环，都会带来难以言说的灾难。因为在公平的自然面前，每个物种，每个独立的生物个体都是如此的美丽而富有价值。

大自然因为物种的多样性而五彩缤纷。想要与她和谐相处并得到其慈祥的对待，就要善待自然，了解自然，并拥有一刻善于发现与创新的心。

Learners of English, especially beginners have troubles in understanding

speeches by native speakers. Bur how to improve listening ability? Here Id like

to introduce you some ways which might help you to improve you listening

ability.

First of all, do things step by step. It is no good to listen to anything

beyond your level . Dont choose too difficult materials .

Secondly, stick to one course of study . Work hard at it until you master

it well .

Thirdly, listen to the English news program over the radio every day. If

you have more time, listen to some interesting stories, too.

There are many ways to improve your listening ability . It is up to you to

find out best ones for you.

If I were a boy again, I would practice perseverance more often, and never

give up a thing because it was or inconvenient. if we want light, we must

conquer darkness. perseverance can sometimes equal genius in its results. “there

are only two creatures,” says a proverb, “who can surmount the pyramids—the

eagle and the snail.”

if i were a boy again, I would school myself into a habit of attention; i

would let nothing come between me and the subject in hand. i would remember that

a good skater never tries to skate in two directions at once.the habit of

attention becomes part of our life, if we begin early enough. i often hear grown

up people say “ i could not fix my attention on the sermon or book, although I

wished to do so” , and the reason is, the habit was not formed in youth.

if I were to live my life over again, I would pay more attention to the

cultivation of the memory. I would strengthen that faculty by every possible

means, and on every possible occasion. it takes a little hard work at first to

remember things accurately; but memory soon helps itself, and gives very little

trouble. it only needs early cultivation to become a power.

There is an old man who lives next to my door. He lives alone, and

sometimes his children will come to visit him. When we asked him why he didnt

move to live with his children, he said he didnt want to interrupt them,

because of the different lifestyle. The man likes to sit in front of the shop,

where people communicate there every day. He is very talkative and likes to

offer help. Once he helped a woman to carry heavy food home. Besides, if people

asked him for information, he knew everything. People loved him and got used to

seeing him every day. I like to talk to this man, he is smart and can give me

some wise opinion. He is definitely a good people and we are willing to ask him

to have dinner with us.
