全文共 598 字
+ 加入清单Should students make friends on line? Some people say yes. The Internet
helps make many friends. Chatting on line, students can express their feelings
and opinions more freely, and even get help with their foreign language
studies.
Others, however, think students should not. They say making friends on line
is a waste of time, which should be spent more meaningfully on study. Besides,
some students, get cheated on line.
It is my opinion that students should place their study, health and safety
before other, things. As for friendship, we can readily find it in our
classmates and other people around us.

篇1:如何写好高中英语日记
全文共 510 字
+ 加入清单日记是用来叙述一天中发生的有意义事件的文体。
第一,注意日记的格式:一般是左上角写当天的日期,右上角写当天的天气情况(cloudy/clear/windy/rainy/fine/snowy…)。日期通常采用两种写法:一种是按“月、日、年”顺序;另一种是按“日、月、年”的顺序。注意要在年份之前有一个逗号,而且月份通常可用缩写词(如:Jan.,Feb.,Mar.等)。如果需要写星期,可将其写在日期的前面或后面。如:Monday,May15th,2008或May15th,2008,Monday
第二,抓准日记的时态:日记记叙的时间通常是在当天的下午或晚上,因此所用的时态多为过去时态。但应灵活掌握,如果日记叙述天气、描写景色或为了描写生动,也可用现在时。
第三,日记一般按事情发生的先后顺序记述,所以常需借助一些表示先后顺序的词语,如atfirst,then,lateron,afterwards,finally,atlast等。一定要注意句与句、段与段之间的连接和过渡,适当使用一些过渡词语使其连接紧凑、过渡自然。
第四,确立日记的中心要点,尽量突出主题,可以通过对某个细节、某个侧面的描写来突出主题,千万不要写成一个流水帐。
篇2:满分高中英语作文
全文共 886 字
+ 加入清单Dear editor,
I’m writing to tell you about the discussion we have had about whether an entrance fee should be charged for parks. 60% of us schoolmates think that an entrance fee do not meet people’s expectations, for a park is considered to be a place where the public can have a good time when they are not busy either at home or at work. If an entrance fee must be paid by the visitors for a park, it will be necessary to build a gate and surrounding walls. In the end a city will take on a bad look. 40% of us schoolmates think that an entrance fee can be accepted, but it must not be too expensive. The money from ticket selling can be used for paying the gardeners in the park and buying some other kinds of flowers and trees.
With regard to myself, I think an entrance fee is useful, for it can be used to protect a park. Do we share the same opinion, dear editor?
Yours truly,
Li Hua

+ 加入清单Youth Day (青年节) in the Peoples Republic of China is on May 4. It was established in December 1949 by the Government Administration Council to commemorate the beginning of the May Fourth Movement in 1919. This day is known as …
May Fourth Movement
Chinese intellectual revolution and sociopolitical reform movement (1917 – 21)。 In 1915 young intellectuals inspired by Chen Duxiu began agitating for the reform and strengthening of Chinese society through acceptance of Western science, democracy, and schools of thought, one objective being to make China strong enough to resist Western imperialism. On May 4, 1919, reformist zeal found focus in a protest by Beijings students against the Versailles Peace Conferences decision to transfer former German concessions in China to Japan. After more than a month of demonstrations, strikes, and boycotts of Japanese goods, the government gave way and refused to sign the peace treaty with Germany. The movement spurred the successful reorganization of the Nationalist Party and gave birth to the Chinese Communist Party. See also Treaty of Versailles.

篇5:关于低碳生活高中英语作文
全文共 1787 字
+ 加入清单An activity about low carbon living
Currently,my school is launching an activity whose theme is that actions change the world to advocate the low carbon living.
In the activity,we are required to go to school or some other place by bike or by foot as much as possible instead of by bus.And when the Christmas comes,sending e-greeting cards instead of tridional cards of which are made of wood as we know.Besides,we should use both sides of every piece of paper and we should save water as well as electricity.
I believe that only we do thus can we have a better living environment.
There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.
To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today. AD:From Joozone.Com.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

Do you know Harry Potter? If you dont, then you are out of date. Many people love Harry Potter, whether children or adults. I love Harry Potter, too. Last week, I went to Nantong to see the movie "Harry Potter and the Goblet of Fire".
It was a wonderful movie. In the movie, Harry is the same age as us and he is more handsome than me. Harrys best friends are Hermione and Ron. The movie tells the story of Harrys Fourth Year at Hogwarts. The Goblet of Five selects him to compete as one of four champions in the Throwizard Tournament, despite the fact that he didnt submit his name. The Tournament is very dangerous so his friends are all worried about him. Hermione and Ron try their best to help Harry to prepare for each task. I think their friendship is unbreakable.

+ 加入清单Hiding behind the loose dusty curtain, a teenager packed up his overcoat into the suitcase. He planned to leave home at dusk though there was thunder and lightning outdoors. He had got to do this because he was tired of his parents’ nagging about his English study and did not want to go through it any longer. He couldn’t get along well with English and disliked joining in English classes because he thought his teacher ignored him on purpose. As a result, his score in each exam never added up to over 60.
His partner was concerned about him very much. She understood exactly what he was suffering from, but entirely disagreed with his idea. In order to calm him down and settle his problem, she talked with him face to face and swapped a series of learning tips with him. The items she set down helped him find the highway to studying English well.
The teenager was grateful and got great power from his friend’s words. Now, he has recovered from being upset and has fallen in love with English.

My mom used to say that I was born to swim. But the truth is that I didn t know how to swim until the last year of my primary school!
Mom always said that I could swim in the basin when I was only two months old. I was surprised at the amazing fact. If this was true, then why was I afraid of water? I went to swim every summer, but I didn t make a little progress. I was worried and blamed myself several times. When I watched people swimming freely, how I wished I had learnt to swim!
The story of how I learnt to swim is dramatic. One hot summer afternoon, my father and I went to the swimming pool to swim. While my father was changing his clothes, I was roaming along the bank of the pool. Suddenly I heard a voice, Look out! and then came a big noise and beautiful splashes. Just when I was admiring the swimmer s skills, I slipped into the pool! I was so afraid that I shouted at once! But the water kept coming towards me and I drank a lot of it. I was moving upside down and trying to reach the bank. I was struggling very hard to keep my head above the water.
A minute was like a hundred years to me. To my surprise, I was able to keep the style! Just then, my father, saw me and he seemed to be shocked. He then said, Calm down, just wave your arms and legs like this. Right! And I got it! I finally learnt to swim! You can t imagine how happy I was and I wanted to jump for joy!

篇13:关于友谊的高中英语作文
全文共 5889 字
+ 加入清单友谊是一条善良的河流,澄清着沿路的风尘;是上天在人的心灵中植下的一方净土,培育着诚实善良的花朵。下面是小编整理的关于友谊的英语作文,希望对大家有帮助。 关于友谊的英语作文一:
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.

Although we cannot choose our appearance, inborn gifts and even avoid unexpected disasters and adversities, we do have the privilege to choose to live optimistcally,to love our lives, to have dreams, and to cherish hopes.

+ 加入清单Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.
Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.
Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

Nowadays, more and more people prefer to travel quite often.By traveling, we not only can relax ourselves but also broaden our knowledge circles.From my aspect, I think we can make many friends and travel with them.
Firstly, we can enjoy the beautiful scenery and relax ourselves.For modern life, we are busy with our work with high pressure.However, when we travel, we will be attracted by great landscape and forget pressure from both work and life.
Secondly, we can make friends by traveling.For most travelers, they tend to find many companions to travel with.If you check the internet, you will find that some people will call others to join them for travel.Through this kind of travel, we can meet many different people and make friends with them to broaden our social circle.
Thirdly, we can learn much knowledge form travel.Before you go to somewhere to travel, generally, you need to make plans for your travel.You can find lots of things you don’t know when you make a plan, such as, the origin of a certain area, the customs of different areas, local food and so on.
In conclusion, we can not only relax ourselves and make new friends but at the same time we can learn much from travel.
【参考翻译】
现在,越来越多的人会经常去旅游。通过旅游,我们不仅能够放松自己,并且也能开阔我们的视野。在我看来,我们可以在旅游中结识到新朋友和他们结伴同行。
第一,我们能在欣赏风景之余放松自己。现代生活中,我们整天忙于工作,压力很大。但是,当我们旅游的时候,我们会被美景吸引,暂时忘记工作和生活的压力。
第二,在旅游中能够交朋友。对于许多旅游的人来说,喜欢与人结伴同游。如果你到网上搜一搜,你会发现有很多人都会叫其他人加入他们去旅游。通过这种方式的出游,我们能见到各种各样的人,与他们交朋友,扩大我们的交际圈。
第三,在旅游中,我们能学到很多的知识。在你想去某个地方旅游之前,通常你需要制定一个计划。制定计划的过程中,你会发现许多你不知道的事情,例如,某个地区的由来,不同地方的人的风俗习惯,当地的美食等等。
总之,通过旅游,我们不仅能放松自己,结识新朋友,同时也能学到新知识。
