Travel by Bike
There are many ways of traveling,People may travel by plane if they want to travel far and reach their destination in a shorter time.It is the most comfortable but expensive way.Most people travel by train because it is a less expensive way but the compartments are cramped and stuffy.Bus journey is a cheaper way but it is spent on narrow,bumpy roads which are crowded with traffic.Trips by ship may be the cheapest and most comfortable way but it takes too much time.
I tike traveling by bike.I can set out when I like and stop when I like.I can go wherever I like so that I can enjoy delightful spots rarely visited by other travelers.When I feel tired,I sit down by the bike and have a good rest.Besides,I can save much money for tickets and much time in waiting for the train or bus.I can cover more places by riding a bike than going on foot.
Traveling by bike is good to health.It is really a sort of good exercise to strengthen one's muscles and to test one's will.Moreover,it brings no pollution to the air.So it helps to clean the atmosphere.

In the last hundred years,people have set a new mind-blowing rate for the developing of new technologies. New produces are being conceived every minute of every day, all of which will impact people in some respects. However,in all these technologies and produces computers have been the most important influences on people. Some people assert that computers have made life more complex and stressful, while some people believe that computers have made life easier and more convenient. From my point of view, the advantages of computers are the leading sides and computers become a necessary part in people＇s lives. Perhaps computers may quicken our pace of life and make our life more complex and stressful. With the development of computers almost every jobs need people who are well up in computer technology. People, who want to find a good job, must learn how to use computers. On one hand,the computer technology is a very complex subject. If you want to use computers very well, you must take a lot of time to study and practice it. On the other hand, computers develop so fast that people must study new technology constantly. Those all make people feel stressful. Even though there may be one or two disadvantages to develop computers, the advantages fast outweigh them. The major point for my penchant for computers is that computers can help people do many things, including complex computation, storing and searching information and some work that is dangerous for people to do. For instance launching a rocket up to outer pace needs so complex computation that people can not do it without computers; searching the newest information is of vital importance for business, so people will not be success in business without computers. Computers have facilitated many of our working processes and we have already grown dependent on them. Another advantage of computers is that people can use them for entertainment in spare time. From pc games to online chatting, computers have the ability to entertain us in a wide verity of ways. After a busy day, playing pc games is the favorite thing of most of my classmates. And in today＇s life, a lot of young people could have not televisions, but they must have a set of computer. Now many films display fascinating images by using computers to deal with them. In a word in spite of the fact the computer appears to have made life more complex and stressful, I fell that the advantages are more obvious. Computers have become an integral part of everyday life. They can help us do much work and make us funny.

广告的利与弊
The advantage and disadvantage of the advertisement
Advertisement is omnipresent in our modern society. It seems wherever we go, such small ads will greet our eyes: the supermarket, the subways, the stop sighs, the walls of public buildings, the garbage cans, and whatsoever. The ads can be about everything from selling mobile phone, renting houses, treating difficult diseases to producing fake diplomats.
（from domestic articles to machinery, from toys to aircrafts.）It’s no exaggeration that we live in the world of advertisement.
The advantage of the ads is self-evident. They provide us with a good collection of goods and service, from which we can make our best choices. For the manufacturer, they can take advantage of the ads to project the characters of their products so as to seize the vision of the consumers and gain them huge profits.
However, we cannot belittle the disadvantages of the ads. ①To many ads do spoil our daily life and waste our time. They interrupt the TV programs, filling our letterbox, and ruin our appreciation of nature in place of interests. People often feel burdened with the ads instead of satisfying with them. ②On the other hand, some of the ads are illegal, spreading false information and planning to treat people who are eager to solve their problems.
It’s high time we took urgent and effective measures to curb this phenomenon. ①Firstly, we should intensify the effects to supervise the ads markets. It’s crucial that we must regulate the ads market strictly to avoid someone’s availing himself or herself of the loophole of the market management. ②Secondly, whoever takes advantage of ads treating consumers should be punished or imprisoned. ③Thirdly, we should educate people to abide by the law and give priorities to honesty and credit. Only when putting these measures into practice, will our society be purified into a paradise for us to live in.
广告的利与弊
广告在当今社会中无处不在.看起来无论你走到哪里,她都会映入你的眼帘：超市、地铁、车站、公共建筑的墙体、垃圾桶甚至T恤衫.广告的内容可以关于任何东西：从卖电话到租房,从治疗疑难杂症到办假证.／（从家用物品到大型机器、从玩具到航天器） 毫不夸张的说,我们生活在一个广告世界里.
广告的优点很明显.它给我们提供大批量的商品和服务,供我们做出最好的选择.对于商家而言,他们可以利用广告展示自己商品的特点,以便抓住消费者的视线来获取利润.
然而,我们也不能小视广告的缺点.①太多的广告会搞乱我们的生活并浪费我们宝贵的时间.它们打断电视节目,塞满我们的信箱,损毁了我们对自然的欣赏代替兴趣.人们通常对它们感到负担而不是满足.②另一方面,有些广告是非法的,传递错误信息并意在欺骗那些想急于解决问题的人.
该到了我们采取紧急并有效措施来抑制这一现象的时候了.①我们应加大市场监管的力度.关键是我们要严格规范市场秩序以避免有些人钻市场管理的漏洞.②任何利用广告欺骗消费者的人都应受到惩罚或入狱.③我们应教育人们遵守法律并把诚实守信放在首位.只有把这些措施付诸实践,我们的社会才会被净化成一个居住的天堂.
下面这篇比较有哲理性：
Nowadays, no matter where you get around in a city or even in the countryside, it is pretty easy for you to find one or two signs introducing a product. This has been increasingly becoming popular in our daily lives. Whether the influence of advertising is good or bad could be examined as follows.
We will start by talking about the merits of advertising. Firstly, advertising is informative, which provides the customers with a quick access to the product needed. Take me as an example. I am a new resident of Guangzhou, a metropolitan city located in the south of China. At the very beginning when moving to this city, I did not have a clue about where to purchase all of the necessities for my newly-bought flat. Thanks to the ads on TV and in newspapers, amazingly almost all of the items ranging from furniture to household appliances were settled within a week. Secondly, consumers can expect to have a best price by comparing and contrasting the prices and specifications of the commodity advertised by different suppliers.
However, advertising involves some defects and I would like to list two of them herein. Initially, the popularity of advertisements has been growing along with the increased layout of design as well as showing up in the marketplace more frequently. The cost will definitely be passed on to the customers. Furthermore, the generation Y would probably lose their individuality because many of them buy the same goods advertised constantly in media during a certain period of time, which makes them appear alike.
After the above analysis of the pros and cons, I tend to be in favor of the positive effects. Undoubtedly, nothing is more important than living in a society where ordinary people can enjoy the conveniences and competitive prices brought by commercials. I believe that the negative effects can be minimized through sustainable economic growth and education.

With the development of our society,competition has become more and more fierce.Competition usually comes as an important and necessary part of our society especially economic affairs.As is widely recognized,fierce competiton has largely promoted our society.Without competition,it is hard to imagine what will offer our world with so much energy to move forward.And as for single person,competition can also force him to struggle and make the most of his potential ability.As a college student,first of all you should ease the potential fear for competition.In fact after realising the importance of the competition you can already overcome such feelings.Then you should show your ability and skills adequately.Do believe that whoever will not ignore you only if they have known your talent.

It can be argued that modern technology makes life easier and more dignified for most of people.The major advantage is that medical science is very progressive and vastly available.Without the needed technology a lot of people would struggle with their health.
One of the biggest concerns about modern technology today is pollution.Vehicles and major manufacturing plants are releasing ever-increasing amounts of carbon dioxide,greatly damaging our health.

弊应该都知道,利比如利用转基因大肠杆菌发酵,菌体培养,医疗药物的提取等,一些实验可以根据微生物的反映映射出其他成果
对于人类一些作物、饲养业也有很多功效：
土壤中的微生物虽然看不见、摸不着,但它们却具有其他生物的不可替代的作用.首先这些微生物在分解利用有机物时可以产生大量的二氧化碳.地球上的二氧化碳有90％是由微生物产生的,这就给生长在土壤上的各种植物提供了取之不尽、用之不竭的能源和食物.
此外,土壤中的微生物能把有机氮变成无机氮.它们有两种转化功能：一种叫氨化作用.含氮的有机物经过微生物分解以后释放出氨.农民将有机肥料进行腐熟的过程就是利用微生物把有机氮转变成氨来供给植物利用.另一种是硝化作用.它是把氨转变成硝酸的过程,而硝酸在土壤中能够形成溶于水的硝酸盐,可以供给植物吸收利用.
微生物还可以将一些有机体分解转化成各种物质元素,使这些元素又回到自然界中使构成生命的物质周而复始地得以循环.如果一棵死树或者一具动物尸体永久不被微生物分解掉,动植物尸体中的种种元就无法回到自然界,可以想象我们生活的地球将是多么丑陋不堪!

Benefits of Tourism
There are a number of benefits of tourism for both the tourist and the host destination.On a large scale it offers a good alternative to some more destructive industries for generating income both on nationally and privately.
The tourism industry encompasses many different areas,so it also creates jobs in many different areas.With tourism comes hotels,resturants,car rental agencies,tour companies,service stations,souvenier shops,sports equipment rentals,and much more.All of this creates many different levels of employment for people in a given community.
In many places the introduction and development of tourism allows local people an opportunity for economic and educational growth that would not otherwise be available.In addition,it allows both the tourist and the local community a chance to experience other cultures,which broadens understanding.
If properly used,tourism generated income can be tremendously beneficial to the host country and it's local communities.Tourism generated income can be used on a national and local level to better education,improve infrastructure,to fund conservation efforts,and to promote more responsible tourism.
DISADVANTAGE:
Place could be damaged or polluted because of tourism.
We kill our precious time aimlessly and misutilise our time in such a worthless things,which neither contribute to help you in fulfilling your responsibilities towards your family and other nears and dears,nor can help potentially in your earning capacity.

With the development of computer technology, the Internet has become more and more popular. Some students regard it as a great helper. Since there is a lot of information on line, you can surf the Internet for any information you need in a short time without working hard in the library. It is also very convenient to communicate with others on by using the Internet. However ,other students think that there is some information on line that is not good for the students. In addition, spending too much time playing games on line will not only have a bad effect on study but also do harm to our health. Therefore, we should make proper use of the Internet. It is of great importance for us to separate good plants from wild weeds.

一篇跨国所包含的问题的英语作文 Mixed marriage encounters more problem
Interracial marriages can cause many problems within the family. Due to the fact that the couple has a different family background, culture, and custom, and social class level, many disagreements can occur. Religion can be a problem. If the two has a different religion then the other one, there is a problem. Because some religions celebrate certain holidays while others don't. In Christianity, for example, Christians celebrate Christmas while Buddudists don't. Eating habits can also be a problem. One might eat certain food the other don't or dislike. After all, their offspring will encounter problems too. Childrens who are mixed are not likely to be accepted in certain areas in a community. They often have a hard time fitting in. Interracial marriage is not a good idea, but it is still alright to marry someone who is different than you.

最大的危害就是涌潮特别大.
喇叭口型的河口,在涌潮时受到海流,天文引力等影响,再加上特殊口形,在河口附近很容易出现特别高的涌潮,如果两岸堤岸比较旧,很容易被涌潮摧毁,这样海潮就会深入内陆,淹没农田、工厂、商业区和居民区,会对附近民众生活造成很影响,而且被海潮淹没过的地区,泥土里的盐碱会比较重,很多作物难以存活,会在以后很长一段时间中影响当地农业生产.

With the development of the Internet and the popularization of computers,shopping on the Internet has become a commonplace in our life.Here consumers can buy almost everything they need.
Shopping on the Internet has a lot of advantages,of which the most important is perhaps its convenience.People don't have to waste a lot of their energy and precious time to go from one shop to another to choose the commodities they like.This is especially desirable to the old,the sick and the busy people who cannot go to the shops in person.The goods come in all shapes,sizes and colors on the Internet.All they need to do is to sit in front of their computers and click the mouses.The commodities they order will be delivered to them promptly.
However,shopping on the Internet also has its disadvantages.The first disadvantage is that the consumers can't see the goods or try them on personally.Sometimes,the real goods may not be the same as what they have seen on the computer.The second disadvantage is that some shops on the Internet are not registered.They will never deliver anything to you after they get the money from you.Once cheated,you will find that you have nowhere to go to complain.

First, mobiles make it convinent for people to keep in touch with each other whevere they are.Especially when they have something important.It reduces the cost for people dont have to travel a long way to get to know the things in person
Second,we can send messages by mobiles with little money,just 0.01 yuan for each short message.
Third, we can also play games or take photoes or listen to music on the mobiles,late we do many things on them with the development of technology.
学生B：I don't really agree with you.Mobile phones also have many disadvatages.The radioactivites may do harm to our health.Sometimes the rings may affect others in public or at meetings.Also, it is not good for students if they bring their phone to school because the student won't pay attention to what the teachers are trying to say.

范文一
Although automobiles have improved our modern life in some way for its speed,convenience,and capacity of carrying things,we have had to pay the price for it.Now,as more and more automobiles have been putting into use,the problems that the automobile has caused are seemed to be more and more serious accordingly.These problems,in my mind,like the accidents,the air pollution,the damage of the ozone layers should be given more attention than anytime before.
There are a lot of problems that has been causing by the automobile.It kills hundreds of thousands of people and disables many more every year.It drinks up our precious fossil fuels that cannot be replaced.New roads for the automobile also eat up our precious farmlands while many children are starving all around the world.These problems are really serious and upsetting many of us.
The most serious problem caused by the automobile is the air pollution.It is said that it emits millions of tons of harmful gas into the air everyday.The dirt air harms our human beings health badly.It can cause a variety of diseases such as plumbism,insomnia,mental disability and even certain kinds of cancer.That is really terrible.
Air pollution caused by the automobile can give rise to even more serious consequences.One thing,it will destroy the ozone layers that protect the lives on the earth from the hurt of the strong and direct ultraviolet rays.Much more ultraviolet can also destroy the fragile ecosystem on the earth.It is just the life circle in which we survive.Another thing is that the air pollution caused by
the automobile can lead to the global warming.If the weather is getting warmer and warmer,the icebergs scattered in both of the two poles of the earth will be melted,which will cause the sea level rising and flooding all the cities and villages along the seashores.The lost of the lives and property will be countless.That is really a tremendous disaster.
I do not mean to deny the fact that the automobile has improved our modern life in many ways.It acts a vital role in our social life.It also supports our industries.It is indispensable in our modern life.We cannot imagine how we can live a modern life without the automobile.However,the problems it has caused today,such as the lives and properties lost,the dirty air and the consequences of the pollution,seems to be more dangerous and obvious than anytime.
Therefore,it will never over do to emphasize the seriousness of these problems and urge the governments and other responsible organizations to solve them
范文二
The use of the motorcar is becoming more and more widespread in the 21st century.Possessing a car gives a much greater degree of mobility,enabling the driver to move around freely.The car owner is no longer forced to rely on public transport to get about.With the building of good,fast motorways long distances can be covered rapidly and pleasantly.And many people are now able to enjoy their leisure time to the full by making trips to the country or seaside at weekends,instead of being confined to their immediate neighborhood.
When,however,considering the drawbacks,perhaps poilution is of prime problems.As more and more cars are produced and used,so the emission from their exhaust pipes contains an ever larger volume of poisonous gas,which not only pollutes the atmosphere but causes actual harm to the health of people.Another serious problem is traffic congestion,endless queuse of cars crawling bumper to bumper through all the main streets.Difficulties in finding parking lots,and the cost of petrol and road tax all add to the driver' s worries.
With both of these advantages and disadvantages of the use of a car in mind,I,personally,prefer to have my own car for work and play.I can have a wider choice of jobs as I no longer have to work locally,and I can make better use of my free time by driving out at weekends.The feeling of independence,and the freedom to go where I please,is what I enjoy most.

A、温室效应的产生就是因为大气中二氧化碳的含量增加的缘故．
B、碳酸水能提供二氧化碳，而植物的光合作用的原料正好是二氧化碳．
C、人工降雨是通过降温的方式使水蒸气遇冷凝结，而干冰的升华正好是吸收热量，使温度减低．
D、大气中含有大量的二氧化碳时，空气阻挡紫外线的能力下降，这也是产生温室效应的一个原因．

The Advantages and Disadvantages of Watching TV

I think TV is the best invention in the world. It change our life a lot, and get the world more close. It put our life out of boring. It become an important part in our life, we can't miss it.
TV can show you lots of imformation that you want, you needn't go any place just stay at home, sit on the sofa and use the remote control. That something funny, miserable, horrific, all under your eyes. And I think watching TV is a good way for relax. It will let you forget something unhappy in the day, and take you to the another world. In that world, you needn't used your brains too much, just follow the thread of the TV.
But if you watch TV for a long time, it's bad for you. Sometime you will feel very tired, and you can't want to do anything. Actually it make you lazy. You wouldn't care anything because you are wallow in the TV show.
It seems to me that TV is a friend to everybody, when you feel lonely, it will accompany you. But we don't put all the time on it, because it isn't your husband or wife.

今天,我怀着愧疚和懊悔给您写下这份检讨书,以向您表示我对上课讲话这种不良行为的深刻认识以及再也不在上课的时候讲闲话的决心.
这是一次十分深刻的检查,我对于我这次犯的错误感到很惭愧,我真的不应该在早自习的时候说话,我不应该违背老师的规定,我们作为学生就应该完全的听从老师的话,而我这次没有很好的重视到老师讲的话.我感到很抱歉,我希望老师可以原谅我的错误,我这次的悔过真的很深刻.
不过,人总是会犯错误的,当然我知道也不能以此作为借口,我们还是要尽量的避免这样的错误发生,希望老师可以相信我的悔过之心.“人有失手,马有失蹄”.我的不良行为不是向老师的纪律进行挑战.绝对是失误,老师说的话很正确,就是想要犯错误也不应该再您的面前犯错误,我感到真的是很惭愧,怎么可以这么的.
相信老师看到我的这个态度也可以知道我对这次的事件有很深刻的悔过态度,我这样如此的重视这次的事件,希望老师可以原谅我的错误,我可以向老师保证今后一定不会在早自习及其他任何课上说闲话的.
今天我真的是很深刻的认识到了我的错误,知道老师说的话就要听从,老师说的话也绝对会实现她的诺言,老师所要管的一定是为了我们学生好,所以我们不用挑战老师的纪律,我们还是学生,没有能力对老师说出来的话产生不听从的想法,我们学生唯一可以做的事情就是好好的听从老师的话,好好的学习好,让老师可以放心,让老师可以信任.
犯了这样的错误,对于家长对我的期望也是一种很大的打击,家长辛苦的赚钱,让我们孩子可以生活的好一点,让我们可以全身心的投入到学习当中,可是,我却违背了家长的心意,我犯了这样的错误,简直是对于家长心血的否定,我对此也感到很惭愧,家长的劳累是我们所不知道的,每天为了生存而忙碌,为了家庭而承受着巨大的压力,这一切的一切都是我们所不能够了解的,我们唯一可以做的就是做他们的乖孩子,听从家长的话,家长是我们最亲的人,也是我们在现在这个社会上最可以信任的人,所以我们就要尽量的避免家长生气,不给他们带来不必要的烦恼.而我们作为他们最亲的人也不能够惹他们生气,这个都是相互的,当我们伤害到他们的心时,也是对于自己心的伤害,因为我们是最亲的人.没有任何人可以取代.
这次的事件我真的感到抱歉,希望老师可以原谅我,可以认可我认错的态度,我真的已经深刻的反省到我的错误了,希望老师再给我知错就改的机会.也希望同学也要引以为戒,不要犯和我一样愚蠢的错误了,这次的教训真的很大很大.
错误的性质是严重的.我在上课的时候讲闲话,并且影响了其他的同学,其结果损害了多方利益,在学校造成极坏的影响.这种行为,即使是并没有影响课堂纪律,仍然是不对的,此举本身就是违背了做学生的原则.我只是顾着自己的一时高兴,和一时的想法,完全不理会老师的感受.这也是不对的,人是社会的人,大家不应该只是想着自己,我这么做,害的那个是那些和我一起讲话的同学,我这样做,看似和他很好,实际上是在害他.而且,在上课的时候讲闲话也是对老师的不尊重.所以,老师把让我写检讨,也是为了让我深刻的认识到这点.
其次,我在上课的时候讲闲话的行为也是一种对老师的工作不尊敬的表现.中国是一个礼仪之邦,自古就讲究尊师重道,这是一种传统的美德,过去我一直忽视了它.抛开着一层面,不单单是老师,无论对任何人,我们都应该尊重他,尊重他的劳动,他的劳动成果.我这样做,直接造成了不尊重老师,不尊重他人,不尊重他人劳动的恶劣影响.作为一名当代中学生,一名正在接受教育的人来说,这种表现显然不符合社会对我们的要求.
再次,我这种行为还在学校同学间造成了及其坏的影响,破坏了学校的形象.同学之间本应该互相学习,互相促进,纪律良好,而我这种表现,给同学们带了一个坏头,不利于学校的学风建设.同时,也对学校形象造成了一定损害,“第八中学”在人们心目中一直是一个学术严谨的学校,我们应该去维护这个形象而不是去破坏它!虽然我在考试的时候写答案给别的同学,这是作弊行为,我和那个同学关系很好,他找我讲话,当时我的也想讲话和认为老师不会发现的侥幸心理之下酿成了现在的后果.虽然与人为善是中华民族的优良传统美德,是当代中学生理应具备的品质.但是现在我才深刻的意识到这不是与人为善.我在在上课的时候讲闲话,还传染其他同学一起,这并不是真的和别人好,而是在害自己和同学们,晚自习是让学生复习一天的学习的课,不论是什么原因在上课的时候讲闲话都是很不对的,违背了做学生的原则.当然,我不能说我是为了和别的同学讨论什么问题才在上课的时候讲闲话,这是不能成为我作弊的理由.鲁迅先生说过：不友善的帮助就是恶意的伤害.我只有认真反思,寻找错误后面的深刻根源,认清问题的本质,才能给集体和自己一个交待,从而得以进步.做为一名学生我没有做好自己的本职,本应该在上课的时候决不讲闲话,而我却在上课的时候讲闲话了,辜负了老师平时对我的教育之恩,老师含辛茹苦的把知识教会我们,是想让我们做一个对社会有用的人,而我却在上课的时候讲闲话欺骗把知识无私的教给我们的老师,我现在已经彻底认识到我的行为不仅没有起到帮助同学的目的,反而是害了他,也对老师是一种欺骗行为.自从接受了老师对我的批评教育,我已经深刻认识到这件事情的严重性,老师教育我说明 老师是非常的关心我,爱护我,所以我今后要听老师的话,充分领会理解老师对我们的要求,并保证不会在有类似的事情发生,如果在上课的时候别的同学找我讲话,我不再参与,而是在主动的去告诉他这样是不对的,这样就可以帮助老师分忧了,帮助老师给班里营造良好的学习的气氛.望老师给我改过自新的机会.老师是希望我们成为社会的栋梁,所以我在今后学校的学习生活中更加的努力,不仅把老师教我们的知识学好,更要学好如何做人 ,做一个对社会有用的人,一个正直的人,使老师心慰的好学生,老师如同父母对我们的爱都是无私的,所以我 也要把老师对我们的无私精神去发扬,通过这件事情我深刻的感受到老师对我们那种恨铁不成钢的心情,我所犯的错误的性质是严重的.我在上课的时候讲闲话实际上就是在班上和系里面造成极坏的影响.这种不择手段的行为,即使老师允许,此举本身就是违背了学生的道德和专心治学的精神、违背了公平竞争的原则.这样一种极其错误的行为就是典型的锦标主义.尤其是发生在我这样的二十一世纪的一代少年身上.弘扬第八中学的拼搏精神,走顽强拼搏进取之路既是我的责任,也是我坚定不移的前进方向.然而,我的行为却背道而驰.一个优秀上进的学生当然要努力争取好的成绩,但不能不顾一切、不择手段地去达到目的,这是一个关系到如何成人,如何成才的一个重大原则问题.一个人的成长和进步,不仅仅是学业上的提高,更重要的是思想、作风方面上的培养和锤炼.我忽视了这样一个重要的问题,为此而犯了方向性的错误.我所犯错误的影响是很坏的.在上课的时候讲闲话,在上课时就直接造成不尊重同学、不尊重老师、不尊重父母的恶劣影响.过去,第八中学不仅是成绩好、思想好,在精神风貌、队纪礼仪、学术建设等方面也享有较好的声誉,而由于我的错误,大大损害了某某中学的形象；本来,老师是对我很器重的,然而,我的错误深深地伤害了他们的心；我所犯的错误,无疑产生了很大的负面影响,带了一个坏头；其他的同学在她们成长的过程中,由于我所犯错误,给她们带来了不应有的负面影响和不应承受的思想压力.总之,们为自己所犯的错误而带来的这一切而深感痛心和后悔. 我所犯的错误教训是深刻的.上级老师,同学都委以重任并寄予厚望,我自己也一直感到责任重大不敢苟且,认真学习,全力投入.但事实证明,仅仅是热情投入、刻苦努力、钻研学业是不够的,还要有清醒的政治头脑、大局意识和纪律观念,否则就会在学习上迷失方向,使国家和学校受损失.我知道,造成如此大的损失,我必须要承担尽管是承担不起的责任,尤其是作在重点高校接受教育的人,在此错误中应负不可推卸的主要责任.我真诚地接受批评,并愿意接受处理.对于这一切我还将进一步深入总结,深刻反省,恳请老师相信我能够记取教训、改正错误,把今后的事情加倍努力干好.同时也真诚地希望老师能继续关心和支持我,并却对我的问题酌情处理.
早在我踏进校们,老师就已三申五令,一再强调,全校同学不得在上课的时候讲闲话,影响课堂秩序和听课效果.可是今天上午我还是在一堂老师给我们精心准备的无比生动的课上讲了话,没有好好吸收一次老师呕心沥血给我们制作的知识大餐.晚修是很重要的,我应当珍惜这个机会,可是我错过了,这莫过于人生的一大损失.同时,老师,您的关心也令我深深地感动,我知道几个人上课讲话对您来说是没有损失的,可是您还是及时发现并教导我,令我下次不再犯.您是多么慈祥,多么伟大啊!我感激的泪水可以添满整个塔里木盆地;我因过分激动而跳跃的心可与唐山大地震相媲美;我浪子回头的决心可赛过女娲补天时的毅力.我坚决保证以后的早自习除极特别的原因我一定会在课堂上认真听讲不讲闲话.如果说把整个太平洋的水倒出来,都浇不灭您对我愤怒的火焰,那么,整个太平洋的水能全倒出来吗?不能,所以我相信你一定能原谅我这次无意间所犯的错误,之所以说是无意间是因为早自习的时候只是无意间说了几句话,虽然这也许只是一个不假的理由,真实就是真实,事实就是我在上课的时候讲闲话了,希望老师能原谅.
对不起,老师!这次我犯的是一个严重的原则性的问题.错误已像光天化曰下的凶器说出了一切事实.
老师反复教导言犹在耳,严肃认真的表情犹在眼前,我深为震撼,也已经深刻的认识到事已至此的重要性.
如今,大错既成,我深深懊悔不已.深刻检讨,认为在本人的思想中已深藏了致命的错误:思想觉悟不高,本人对他人的尊重不够,以后我将对老师有更多的尊重.对重要事项重视严重不足.平时生活作风懒散,如果不是因为过于懒散也不至于如此.
我辜负了您的一番心血,事无巨细.见微知著,由小及大,我作为一名初2学生还像小孩子一样在上课讲话,给全班作了坏榜样造,成了极恶劣的影响,对于这件事情,所造成的严重后果我做了深刻的反思:

Nowadays ,computer is a part of our life.And computer games are children's favorite.Computer games can make us feel relaxed and excited ,but they can also cause us some problems.For example,they may make us forget to study ,to do homework,ect.
So,I suggest:play few computer games and do more meanful things.Just play it in spare time .If you are so crazy about computer games that you have no interest in your schoolwork and don't listen to teachers as carefully as before in class.Also,you can't hand in your homework on time.Perhaps playing computer games can make you feel relaxed,but if you spend too much time on it,you will have less time to study.And it may do harm to your health.For example,it can hurt your eyes and neck

权：称砣.衡：称杆.权衡：比较,衡量.比较一下哪一个有利哪一个有害.
意思是对于一件事,自己首先要想想、比较一下那个对自己有害或者有利和自己得到或者失去什么,这样才能稳操胜券、得心应手,有心理准备
