We havebeen told when we were a little child that we help others as they are in need. Weoften do as what we were told in the childhood, but when we grow up nowadays weare not dare to help others.

Because the society becomes more and complicated. Thereare some people will make traps for the kind people.

For example, you see anold lady falling on the ground and you would like to help her. However, you maybe charged for pushing her down and ask you to give money for seeing a doctor. Yeah,this things often happen.

But helping others is the traditional for ourChinese, we should carry it out on any condition. Helping others will not onlyhelp other people but also help yourself.

You will feel happy and satisfy whenassisting others. So please give a hand to the people in need carefully.

我们在很小的时候就被告知要帮助那些需要帮助的人。

我们小的时候经常就像被告知的那样做,但当我们长大了,我们却不敢去帮助别人了。

因为社会变得更复杂了。有一些人会对善良的人设陷阱。例如,你看到一个老太太倒在地上,你想帮她。

但是,她可能会说是你把她推到的并让你赔偿医药费。是的,这种事情经常发生。但帮助他人是我们中国的传统,不管在任何情况下我们都要发扬光大。帮助别人不仅可以帮助别人也是帮助自己。在帮助他人时你会感到快乐和满足。所以请小心的帮助需要帮助的人。

篇1:垃圾分类环保高中作文

全文共 788 字

+ 加入清单

生活中,人们避免不了产生垃圾。垃圾是宝物,可是是个“调皮的宝物”。你怎么对它,它就怎么对你。你对它好,它就造福人类;你对它差,它就祸害地球和人类。所以,垃圾分类是变废为宝的措施。

我们家也进行了垃圾分类。我们家有四个垃圾桶呢。厨房一个,装厨余垃圾;厕所有一个,装不可回收垃圾;客厅有一个,装可回收垃圾;阳台还有一个,装有害垃圾。要知道我们家的垃圾分类却是因为我的一件小事引起的。

记得我7岁的时候,有一天出去玩。那时正值七月,太阳晒得人都快成人肉干了。碰巧经过一家超市,我看见超市里的各种饮品,谗得直舔嘴唇。我掏了掏腰包,刚好2元。我冲进去,买了一瓶汽水,一拉,便“咕噜咕噜”一口气喝完了。前面有一个垃圾桶,我想都不想就随手一扔,扔进了一个“有害垃圾”框。

我漠然地走开,好象垃圾分类与我无关似的。一路上还哼着小调。刚走出不远,来了一对母子,那弟弟看上去比我还小。只见他一手拿着废本子,一手拽着妈妈的衣袖问:“废本子是什么垃圾?”妈妈弯下腰,笑着对他说:“哎呀,儿子你也懂得垃圾分类啦,真棒!废本子属于可回收垃圾。”那小孩“哦”的一声跑过去,飞快地将本子丢进“可回收”桶里。转过头冲妈妈一笑。随后,母子俩走远了。留下我独自一人脸红,发呆。

我的内心泛起一阵一阵的波澜。是呀,为什么一个比我还小的孩子都懂得垃圾分类,而我却不能做到呢?我咬咬牙,飞快跑过去,伸出手将我丢的垃圾捡出来,让它“回家”。瞧!那汽水瓶似乎在对我笑哩:“谢谢你啊,帮助我找到正确的‘家’。”

从那以后,我意识到了垃圾分类的重要性。话说“语言不如行动”我立即向家人和邻居宣传垃圾分类。同时做好自己家的垃圾分类:有害垃圾,不可回收垃圾,可回收垃圾,厨余垃圾。例如塑料瓶就必须丢进可回收垃圾桶,决不乱丢乱放。乱丢乱放就像逃避了自己对环境保护的一份责任一样,有种强烈的负罪感。

让我们一起参与其中吧,帮垃圾找一个“温馨的家”!

篇2:高中生英语作文写作训练方法

全文共 1545 字

+ 加入清单

中学英语教学大纲中明确指出:“写是书面表达和传递信息的交际能力。培养初步写的能力,是英语教学的目的之一。”在近年的高考中英语写作也占有相当比重。因此,在高中阶段教师应在指导和组织学生进行英语写作上下功夫,在平时教学中应有计划有目的地去训练和提高学生的写作能力。

一、学生能充分认识英语写作的重要性是写作能力提高的必要条件。

英语写作能力的提高需要持之以恒的长期训练。如果学生对写作重要性认识不够,他们就不能积极主动地去配合老师搞好写作训练,甚至产生逆反心理,产生对立情绪,英语写作就会半途而废,达不到预期目的。

在平时教学中,老师要经常性地有意识地对学生进行写作重要性的教育。学生一进入高中就要让他们了解初中和高中英语教学要求的异同。

我给学生找几份中考和高考题,帮助他们了解中考和高考英语试题对基础知识和基本技能要求的相同之处和不同之处,引导他们转变观念,更新和完善学习方法,要让他们了解到英语写作在高考中、实际运用中以及对将来继续学习英语的重要性。

我还联系在过去高考中英语取得优异成绩的毕业生,用书信介绍学好英语的方法,特别是在英语写作方面的成功经验和英语写作对他们当时及后来英语学习的重要性。这些毕业生有很大的感召力,很有说服性,尤其对那些有逆反心理的学生。

二、指导写作应注意的几个问题:

1.教师要有明确合理的教学计划和教学程序,组织系统规范的有序训练。

2.帮助和要求学生养成积极主动地坚持英语写作的良好习惯。

3.坚持循序渐进的训练原则。写作要先易后难,先短后长,先学会运用简单句、并列句,后学会用复合句表达,先写正确句子逐步过渡到围绕一个人、一件事、一个观点去写有中心的文章,由不限定时间到限定时间,由限定时间长到限定时间短,由限定字数少到多……

4.分程度要求。对学生的要求不能一刀切,对学习好的要求要高,对学习差的要求要适当低一些。要避免有些学生轻而易举垂手可得,而有些学生又可望而不可及的情况发生。

5.注意讲评。要经常指出优点,以利模仿,指出缺点,警示避免。

6.鼓励优秀,耐心帮助差生。充分利用板报、专栏进行优秀作文展览,或者也可采用传阅方式进行。但不能放弃或岐视差生,要经常帮助他们树立信心,掌握写作方法和技巧。

7.基础知识和能力并重,听说读和写并举。教师在平时教学中应充分利用一切可以利用的机会启发引导学生提高自己的写作水平。如遇到优秀的句、段或篇提示学生注意欣赏作者的表达法,把它们作为范例,在自己写作中加以模仿和运用。又如遇到英汉表达方法不同之处,提示学生注意英语的正确表达法,切忌出现汉语式的英语。要帮助学生养成正确运用标点符号的好习惯,切忌一点到底的错误方法。

8.要求学生在写作中宁简勿误,不能养成随随便便的习惯,要养成严谨推敲的风气。

三、训练写作的常用方法。

写作训练应考虑循序渐进的原则,采取逐步提高的形式进行。

1.用学过的词、短语或句式,模仿课文中的表达法造句。2.换课文中的人物、时态、语态或体裁等改写课文。3.看图作文。4.填补式作文。5.写课文复述材料或写心得体会。6.将打乱顺序的句子按事件发展的时间顺序或逻辑关系等整理成一篇完整的短文。7.教师给出题目和提纲让学生写作。8.写日记或周记。9.材料作文。教师给出汉语提示让学生用英语表达。

四、注意纠正学生英语作写中容易出现的错误。

学生最初写作时,教师要给予必要的指导,使他们少犯错误。教师还要经常性地例举错误的表达法,提醒学生注意避免。在批阅作文时教师要随时标出学生错误之处,还要随时记录学生所犯错误,把学生的错误加以归类总结,把普遍性的错误提出来,让学生集体改错,使他们的语言表达尽可能地规范正确。

总之,学生英语写作能力在老师有计划的组织和耐心帮助、正确引导下,在学生长期积极密切的配合下是能够得以逐步提高的。

Today, I saw a cartoon: a logger in his axe in his hand cut down a tree, his side with a woodpecker pecked him on the head, think theres a bug in his mind.

The picture from the Angle of the woodpecker exposes human for their own interests at all costs and make things, also warned us: if we dont pay attention to protect the natural environment, our every bit of damage to nature will eventually fall on our heads.

In fact, our lives are like the loggers in the cartoon. For example, in the corridor of the school, the playground, we often can see be knead into a ball of paper and some paper planes did not write a word. They were only the foot on the ground, they are homeless. A complete book, being ripped and torn, so little. This is book that students who do not know to save. Without a rubber wipe after they write a typo, but directly pull down, knead into a ball casually, so resolved, regardless of the consequences of abuse.

If everyone in the world to protect the environment, then the world will be more beautiful! We also learned a few words: be gentle with the earth is to yourself; Save the earth is to save the future. Human in the destruction of the earths environment and hurt himself, at the same time, as long as we change, protect earths environment is to protect yourself. Lets join together to love the earth, love of the natural environment! Let us hand in hand for the beauty of the earth to create a green home!

今天,我看见了一篇漫画:有一个伐木工拿着斧头在砍树,他的旁边有一只啄木鸟不停地啄着他的头,认为他的脑子里有虫。

这幅漫画从啄木鸟的角度揭露了人类对为自己利益不惜任何代价而做出的事,同样也告诫我们:如果我们不注意保护自然环境,我们对大自然的每一点伤害终究会降临到我们头上。

其实,我们的生活中也有像漫画中的伐木工那样的人。比如说:在学校的走廊上、操场上,我们常常都能看到被揉成一团的纸团和一些一字未写的纸飞机。它们在地上被无数只脚踩,它们无家可归。一个完整的本子,被人撕了又撕,就这样所剩无几了。这都是那些不懂得节约的同学的大作。他们写错字后不用橡皮擦擦,而是直接扯下来,揉成一团随便一扔,就这么解决了,不顾后果地滥用。

如果世界上所有人都保护环境,那么世界将多美好啊!我们也学了几条名言:善待地球就是善待自己;拯救地球就是拯救未来。人类在破坏地球环境的同时也在伤害着自己,只要我们换一换,保护地球上的环境就是保护自己。让我们一起加入到热爱地球,关爱自然环境的行动中来吧!让我们手拉手为地球创造一个绿色的美好的家园吧!

导语:每个人都有自己的妈妈,你喜欢你的妈妈吗?下面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!

My mother has no idea that her ninetieth birthday is coming up. She has no notion of the time of day, the day of the week. the season of the year, the year of the century. No notion of the approaching millennium. And no idea any longer, who I am. Her forgetting of me happened just a few months ago, after I had been traveling for more than a month and hadnt been to see her. When I came back, she asked me if I were her niece, l said no, I was her daughter. "Does that mean I had you?" she asked. 1 said yes. "Where was I when l had you?" she asked me. I told her she was in a hospital in Far Rockaway. New York. "So much has happened to me in my life." she said "You cant expect me to remember everything."

My mother was once a beautiful woman, but all her teeth are gone now. Toothless. No woman can be considered beautiful. Whenever I visit her in the nursing home, she is sitting at the table in the common dining room, her head in her hands, rocking. Medication has eased her anxiety, but nothing moves her from her stupor except occasional moments of fear, too deep for medication. This is a room that has no windows, that lets in no light, in which an overlarge TV is constantly blaring, sending images that no one looks at where the floors are beige tiles, the walls cream colored at the bottom, papered halfway up with a pattern of nearly invisible grayish leaves. Many of the residents sit staring, slack-jawed, open mouthed. I find it impossible to imagine what they might be looking at.

When I walk into the dining room on the day of my mothers birthday, I see that she has already been served lunch. The staff has forgotten to hold it back. Though I told them a week ago that I would be providing lunch. She hasn’t touched anything on her tray except a piece of carrot cake, which she holds in her hands. The icing is smeared on her hands and face. I dont want my friends to see her smeared with icing, so I wet a paper towel and wipe her. This fills me with a terrible tenderness, recalling, as it does. a gesture I have performed for my children. As I wipe my mothers face, I see that her skin is still beautiful I hold her chin in my hand and kiss her forehead. I tell her its her birthday, that shes ninety years old. "How did that happen?" she asks. "I cant understand how that could happen."

l have brought her a bouquet of crimson, yellow, and salmon-pink snapdragons. She likes the flowers very much. She likes the name. "Snapdragons. It seems like an animal thats going to bite inc. But its not an animal, its a plant. Thats a funny thing,"

I have bought food that I hope will please my mother, and that will be easy for her to eat: orzo salad with little pieces of crayfish cut into it, potato salad, small chunks of marinated tomatoes. I have bought paper plates with a rust-colored background, upon which are painted yellow and gold flowers and blue leaves.

My friends Nola and Gary come for my mothers birthday. When we are about to leave, I tell my mother that Im going on vacation, mat I wont see her for three weeks, that 1 am going to the sea. "How will I stand that, how will I stand thats she says, but I know that a minute after I’m gone shell forget I was there.

Generally, there are two tesons for the spam epidemic.

那是一个夏日的早晨,太阳火辣辣地炙烤着大地,整个世界就好像变成了一个大蒸笼,随着阳光的照射,变得越来越热。教室里到处都弥漫着一股汗的酸臭味,同学们正在一起有说有笑的聊着天。

在这明亮的教室外,一个不起眼的墙角,有着一堆散乱的垃圾,那里是废纸巾、小纸团、旧文具、同学们上课偷吃的糖纸的“家园”,它们孤零零的待在那里,散发着阵阵臭味,像极了一座坐落在墙角里的无助的小岛。

这时,小宇刚刚上完厕所回来了。他穿着一身小西装,板着脸,慢悠悠的向着教室走来,当他走到墙角边时,朝着垃圾瞧了瞧,冷哼了一声,朝着那座小山一般的恶作剧地踢了一脚,垃圾散得更开了。他抬起头转身就走,嘴角微微扬起,露出了一抹诡异的冷笑:“啊哈,这下有好戏看了,今天值日的小叶要遭殃了”。

过了一会儿,班上的纪律委员小婷也随之走了过来,她穿着一条漂亮的裙子,蹦蹦跳跳地跑着。当经过这一地的垃圾时,不由得撅了撅嘴,拍了拍自己漂亮的红裙子,小心翼翼地跳开,嘴里不停地抱怨着:“好脏啊!到底是哪个懒鬼把垃圾倒在这里,我一定要去告诉老师!”说着便怒气冲冲地向着办公室跑去。

这时,又一个小男孩风风火火地从垃圾边跑过,突然,他的口袋里掉出一个漂亮的白色贝壳,那个贝壳是一个手工制作的怀表,里面有一张小男孩和他妈妈的照片。小男孩像与贝壳心有灵犀,贝壳一掉,他就发现了,弯下腰,也不管垃圾堆脏不脏,伸出手来就在垃圾堆里翻找。当他找到贝壳之后,手上已经沾满了灰尘,那堆垃圾也铺得更开了,几个纸团似调皮的孩子,离家出走了。

不久后,又是一个女生向这儿走来。她叫小洛,成绩一般,也没有什么值得夸耀的才艺,可以说是默默无闻。她也看到了墙角的那堆垃圾,先是一愣,然后皱起了眉头,心想:“垃圾怎么倒在这个地方?天气这么热,都已经发臭了。不行,得扫一扫!”想着,她便默默地拿起了扫帚打扫了起来。

她先用扫帚将散落的垃圾细细归拢,再扫进畚斗里。有个纸团被风吹着往前跑,她赶紧上前两步,用扫把按住纸团,也不顾脏,弯下腰捡到畚斗里。扫完后,她又跑下楼,倒掉垃圾,等回来时,鼻尖上已经沁出晶莹的汗珠。她看到被自己打扫得干净整洁的地面,满意地笑了。

扫去堆在墙角的垃圾只是一件小事,但很多人视而不见,能真正去做的人很少,这种默默奉献的精神尤为宝贵。

I recall my study experiences. Sometimes I studied with my classmates, but sometimes I prefer to study alone. In my opinion, learning collaboratively can help us to improve our ability of communication. At the same time, it can give us a stage where we can exchange our thoughts with each other. In addition, through learning collaboratively we can get more chance to know our classmates. But there are some disadvantages. For example, during the time of study, we may not study but talk with our classmates.

回想起我的学习经历。有时候我会和我的同学一起学习,但有时候我喜欢一个人学习。在我看来,集体学习能帮助我们提高我们的交际能力。同时,也可以给我们一个互相交流想法的舞台。此外,通过集体学习可以获得了解同学的机会。但也会有一些缺点。例如,学习的时候,我们可能会和同学聊天而不是学习。

As a matter of fact, learning individually also has some advantages. Firstly, if we study alone, we will think about something by ourselves. It can help us to improve our ability of thinking by ourselves. And learning individually is good for our creation.

事实上,一个人学习也是有好处的。首先,如果我们单独学习,有些东西我们就得自己思考。这可以帮助我们提高我们的思维能力。而且,单独学习有助于我们的创造力。

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.

The importance of English rests with the language being used in most countries in the world as a communicating tool. For example, a German and a Chinese cant speak opposite sides language, but they both know English. And then there is no problem between their language communication. We must know the importance and learn the language earnestly.

The key to learn English well is to recite words. Words are the bricks of language building.Only keeping them in our mind, can we master them. To learn English well,we need to listen more English broadcast and contact with more foreingers so that we can practise our listening comprehansion.

下面是一个鱼和大海的的故事,有一天,大海退潮了,沙滩上躺满了“搁浅”的鱼,眼看就要干了。这时有一个小男孩在岸边,把鱼一条条捡起来,然后扔回大海。一个成年人走过来,不屑的说:“沙滩上有这么多鱼,就凭你,能救几条,有谁在乎呢?”小男孩捧着鱼,坚定地说:“这条在乎!”……环保,刻不容缓,需要我们从点点滴滴做起!个人的环保行动就似一盏灯,一盏灯亮了,给我们带来了些许光明,如果大家都点亮手中的那盏灯,世界将一片光明。日常生活中,我们要时时提醒自己,注意环保:听音乐把音响和电视声音开小一点,减少噪音;洗衣服使用无磷洗衣粉,减少污染。交通出行方面少开私家车,选择公共交通工具出行,选择环保型的汽油和柴油;尽量购买本地产品,少用一次性制品;不随地扔垃圾,看到地上有废纸,弯腰将其捡起;生活垃圾合理分类,集中废旧电池,送进废旧电池回收箱,不可回收的垃圾扔进垃圾箱。路遇绿色草坪,脚下留情绕道行走;保护野生动物,不贪图美味,将其残忍剥皮吃肉……这些都是我们需要时刻谨记在心的。做到环保,仅仅这些是不行的,需要我们做的还有很多,我们要从自身做起,从身边的小事做起,为创造我们的美好家园贡献自己的一份力量。环保是爱护我们家园的必修课,也关系到社会经济的发展和我们的生活健康。保护环境人人有责,就让我们做一个孩子一样的人,一起点亮手中的灯共同前行!

在学校里,感受着校园绿色植物为我们带来的清新空气,总觉得心情要好上好多。想一想,现在我们的生活已经向高质量,高档次,高水平的方向发展了。但是,在享受物质生活的同时,我们的生存环境也在发生着变化。从前的青山绿水,如今已是高楼大厦。难得见到一片森林,却失望的发现旁边,是工厂高高的黑烟囱……看着一天天严重的环境问题,我们束手无策。其实不然,你知道吗?在我们生活中许多不为人知的细节上,有很多容易疏忽的环保细节。平日里,如果有喝过了的饮料瓶,最好不要随手扔掉。我们可以把它们集中起来,到一定的时候,就可以把收集的饮料瓶卖掉。还能收获一笔小小的零花钱。重要的是,如果把塑料瓶集中到一起处理的话,把塑料瓶送到再生工厂,经过粉碎、清洗、干燥等过程就可以得到二次塑料原料,可以制造出其他的塑料用品。这样,节约了不少的资源呢!除了最熟悉的塑料瓶,我们也要回收其他的生活垃圾。处理垃圾是一件非常麻烦的事情:垃圾的生产量每年每天都在增加,专门用于填埋的土地越来越难找到。垃圾中还有化学物质,可能会在不知不觉中污染到地下水源和土地。对于垃圾,我们可以把他们利用起来,制成小工具,装饰品:用废布拼贴成手提袋,坐垫;书可以一直使用到不能继续使用为止,如果有用不上的旧书可以用于没捐活动;把废旧的电池收集起来,而且最好使用环保电池……如果你知道,回收一吨纸可以制造出八百公斤的再生纸,这相当于少砍了十七棵树。易拉罐完全可以百分之百的再利用。科学家已经研究出了通过旧的塑料制品和碳粉结合的代金属原料……如果每一个人在丢垃圾之前都可以想一想这些,无形中也减少了不少不必的浪费。除此之外,我们还要学会保护资源,尤其是——水。现在,全国每天有快一吨的污水直接排入水体,三十五个重点湖泊有十七个被污染,三分之一的水体不适于灌溉百分之九十以上的城市水域严重污染,百分之五十以上的城市水源不符合饮用水的标准百分之四十的水源不能饮用……我们要有节水的意识,时刻检查自己家中的自来水管道是否完好,是否漏水。少使用清洁剂,减少水的污染。如果见到水管破裂应及时拨打啊抢修电话……我们的水来之不易,一定要好好的珍惜。我们要关心大气质量,我们无时无刻不在呼吸。空气中的尘埃粒子在不断的变多,各种废气,浓度越来越高……请爱护身边的花草树木,植树造林,保护身边的绿色植物我们的绿色守卫军!生活中的点滴都会是我们低碳生活的一部份,我们要从身边的每一个地方做起,低碳生活,每人出一份力,让生活更美好。

There are many important people have been in my life, and one of them I will never forget. I met him last summer. He was short and tanned, and was about twelve years old. He was selling the balloons on the sideway when I met him, I was curious and asked him:” why do you do business at such young age?” he said:” I’m not doing business, I have been saving money. I want to donate it to the disaster area, the children there need help.” I was surprise, and ashamed. I bought many balloons from him and asked him to keep the change. I should learn from him to be a kind-hearted person.

在我的生命中出现过很多重要的人,其中有一个非常难忘。我是在去年夏天的时候遇见他的。他个子很矮,皮肤黝黑,比我年纪还小。我遇见他时他正在路边卖气球,我非常好奇就问他:“你为什么年纪那么小就做生意了?”他回答说:“我不是在做生意,我正在存钱。我想把钱捐到灾区,那里的孩子们需要帮助。”我感到很惊讶,也很惭愧。我向他买了许多气球,不用找零。我应该像他学习,做个有爱心的人。

Recently, the movies about the old people happen to have the magic and then

come back to their 20 years old time are very popular. The old people do all

kinds of crazy things that they never have the chance to do. These movies tell

people that given another chance, they will do whatever they want to do. I

always hear my parents said when they retired, they could carry out all kinds of

their plans and enjoyed the life. In my opinion, when we are young , we shuold

enjoy our moment and chase our dream. It is a little to carry out the plans when

we are old. Youth is the advantages.

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.
