+ 加入清单The Internet is indispensable in real life, it has become a part of peoples life. The Internet has both advantages and disadvantages, so let me say it.
In terms of interest, one: broaden your horizons. It also enriches the brain. 2: it is possible to communicate with each other, and one of the shortcomings of students is that they lack confidence and can overcome obstacles on the Internet. Third, it can promote the development of adolescent personality. Can reduce the pressure of homework. Talk to your friends about your worries. Four: can exercise writing pen, can have a sense of achievement. Five: can grasp the new education dynamic, the online test paper has everything, the student can choose freely. Teachers can also learn about new teaching methods.
There are three reasons for this. One: the Internet is just a virtual world. There are many pitfalls. For example, some unhealthy websites, high school students are not very good, only harm themselves. 2: the Internet is full of aggression, abuse and lying. We can say what we want, without any responsibility! Its immoral not to think about other peoples feelings at all. 3: according to the law, under the age of 18 years of age is not allowed to enter net bar!
Every new thing comes with a variety of worries, from films in the 1920s to the popular music video games. The focus of concern is violence, pornography, decadence and so on. There is a thin line between good and bad. Often "a miss is as good as a mile." The same goes for the Internet. The boundary between profits and profits is a disadvantage.
As a student, I am for myself on the Internet. We need not only to relieve the pressure of study, but also to replenish our food supply. Admittedly, most of us surf the Internet for better learning. In this sense, the net is the advantages and disadvantages.
The network is illusory, it is progress. The Internet is good for the bad, its up to you.

+ 加入清单What is your favorite kind of music? Do you like jazz, popular music,
classical music, folk songs, blues, and so on? In high school I took one course
called music appreciation which I greatly enjoyed. This was not to learn how to
play a specific instrument but to learn how to read and listen to music as an
art form. We read the stories about the lives of many composers and the history
of the musical instruments themselves. Sometimes we listened to tapes at the
language laboratory, or concerts. Music is sometimes called a universal
language. A composer who cannot speak a single word of our language can make us
feel joy and pride, exaltation and despair, peace and mystery through his
music.

I earnestly hope to lead a healthy and prosperous life in the future. Judging from my aptitude inclination and personality streaks, my ideal life will be that of a scientist, researching, lecturing, and writing books. As I am from a farming family, I particularly enjoy being close to earth. If I can afford to live a pastoral life in the countryside, I will feel most blessed. As far as social life is concerned, simplicity is what I intend to pursue, so I really dont need too many friends. All these will be mere talk if I am idle now. To attain my goal, I must make a point of training my body and mind. This is a highly competitive society in which everyone is eager to come out on top. That is not only a competition of physical strength and mental power, but a marathon of patience, faith, and perseverance. Life is not all roses, but with what I am being equipped with by the top teachers in this elite school, I surely deserve a promising prospect.
【参考译文】
我恳切地希望将来能过着健康而顺遂的一生。从我的能力倾向及人格特质来判断,我理想的生活方式将是担任一名科学家,从事研究讲学以及著作。由于我来自农家,尤其喜欢亲近土地。如果我有经济能力在乡下过着田园生活,我会深感福佑。至于社交生活,「单纯」是我所要追求的,所以我确实不需要太多的朋友。如果我现在懒散,这一切都将流于空谈;要达成目标,我必须重视锻炼自己的身心。这是一个高度竞争的社会,人人都渴望拔得头筹。那不但是一场体力和脑力的竞争,也是耐心、信心和毅力的马拉松。人生并不全是美好的事,但以我目前得自这所精英聚集的学校的顶尖老师所施的教化,我必定有个光明的前程。

篇7:高中英语作文写作技巧
全文共 1148 字
+ 加入清单1、审题:审题是做到切题的第一步。所谓审题就是要看清题意,确定文章的中心思想、主题,并围绕中心思想组织材料。
2、进行构思,列出简单的提纲,打造文章之骨架:审好题、立好意后,就要写提纲,打造文章的骨架。文章布局要做好几件事:安排好层次段落,铺设好过渡,处理好开头和结尾。
3、扩展成文:根据字数多少扩展成篇。扩展的内容一定要紧扣主题,千万不要写那些与主题不相关的内容。展开的方式包括:顺序法、举例法、比较法、对比法、说明法、因果法、推导法、归纳法和下定义等。可以根据需要任选一种或几种方式。
在这一步骤中还需注意三方面问题:
1、确保提纲中段落结构的思路与各段主题句的一致性。只有这样,才能保证所写段落不偏题、不跑题。
2、要综合考虑各个段落的内容安排,避免段落内容的交叉。
3、用好连接词,注意段落间、句子间的连贯性。要做到所写文章层次分明,思路清晰,文字连贯,就需要在句与句之间、段与段之间架起一座座桥梁,而连接词起的正是桥梁作用。
在扩展的过程中也有些窍门,以下几点可供参考:
1、在整篇文章中,避免只是用一两个句式或重复用同一词语。英语中存在着极为丰富的同义词,准确地使用同义词可以给读者清新的感觉。同时要灵活运用各种句式,如倒装句、强调句、省略句、主从复合句、对比句、分词短语、介词短语等,从而增加文章的可读性。
2、使用不同长度的句子。如果一个意思用一句话写不清楚的话,通过分句和合句或用两句、三句来表达,增强句子的连贯性和表现力。
3、改变句子的开头方式,不要总是以主、谓、宾、状的次序。可以把状语至于句首,或用分词等。
4、学会使用过渡词。递进furthermore,moreover,besides,in addition,then,etc ;转折however,but,nevertheless,afterwards,etc ;总结finally,at last,in brief,to conclude,etc ;强调really,indeed,certainly,surely,above a11,etc ;对比in the same way,just as,on the other hand,etc。
5、确定文章用第几人称写,基本时态是什么。使用人称时人物不能张冠李戴或指代不明。时态要尽量保持一致。
检查修改:要检查复核,不要写完了事。
要留时间通读全文,修改可能出现的错误。检查上下文是否连贯,句子衔接是否自然流畅。检验的标准主要是句子是否通畅,该用连词的地方用了没有,所用的连词是否合适,是否有语法错误,主谓是否一致,动词的时态、语态、语气的使用是否正确,词组的搭配是否合乎习惯,是否有大小写、拼写、标点错误等,还有就是注意卷面整洁。
可归纳为:中心突出,主题明确;层次清楚,条理清晰;表达

+ 加入清单Mid-autumn Day is a Chinese festival。 It usually es in September or October 。On that day we usually eat a big dinner and mooncakes。 It is said "Hou Yi" missed his wife,so he made mooncakes。 It looks like the moon。

篇9:高中英语写作提分技巧
全文共 2570 字
+ 加入清单一、遣词方面:用词要贴切而丰富,善用短语 ,词汇是语言的建筑材料,文章的好坏,选词很关键,如果用词精湛,就会使文章“亮”起来。
1、措辞要贴切具体
试比较下面句子:
A man is walking down the street.
A man is strolling down the street.
通过比较可以看出,前一句不如后一句表达得具体、生动。一个词如果内涵越具体,那么在特定的场景中恰当地使用它,就会收到意想不到的效果。很多同学写作时常随便用一个很笼统的词来描述一个具体事物或人,如 a nice man给人感觉很笼统空泛,我们可以用很多有个性的、具体的词描绘一个人,如 generous(大方的,慷慨的),humorous(幽默的),smart(漂亮的,潇洒的),kind-hearted,warm-hearted,hospitable(好客的,招待周到的),gentle(文雅的),optimistic(乐观的),easy-going(随和的),spirited(英勇的),cultivated(有教养的),manly(有男子气概的),knowledgeable(知识渊博的)等等。
2、要善于运用短语
短语用得好,会给评卷员留下深刻印象。如:
When he was a child,he wanted to learn everything.( 普通)
When he was a child,he had a strong appetite(胃口) for knowledge.(高级)
3、要避免汉语思维
用词要符合英语习惯,避免汉语思维的影响,如某些名词和动词搭配已约定俗成,不能随意打乱其搭配习惯,否则会显得生硬和词不达意。如汉语中的“学到知识”,英语中就不能说“learn knowledge”,而要说acquire knowledge (获得知识) 。类似的动宾结构还有achieve success (获得成功),gain reputation (获得声誉),attain ones end (达到目的)等。
二、造句方面:句式要准确而多变,活用复合句
简单句用得太多,会造成文章读起来乏味。在评卷员看来,同样意思的内容,能够运用比较复杂的句式结构来表达,当然会认为其运用语言的能力要比只会用简单句来表达要强,评分自然就高。
1、巧用非谓语动词
运用非谓语动词,可使文句看起来更简洁,使语言更加丰富多彩,重点更加突出,增加文采。如:
I covered my ears,trying to keep the noise out,but failed. (2004广东卷)
2、巧用with复合结构
“with+名词/代词+现在分词/过去分词/形容词/副词/介词”结构,常作伴随状语以增加被描绘内容的生动性和情感性,使文章读起来更简洁明了。试比较:
I couldnt go on studying because there was so much noise troubling me. (普通)
I couldnt go on studying with so much noise troubling me. (高级)
3、巧用复合句
高考评分标准强调使用语法结构的数量和复杂性,鼓励考生尽量使用较复杂的结构,并且对由此产生的错误采取了宽容的态度。如果恰当运用各类从句,就会使文章出彩。
如:(定语从句) Whats more,people have easy access to the Internet,which enables them to send and receive e-mails whenever they like.
4、巧用倒装句、感叹句、强调句、虚拟语气句等
使用这些句式可使文章化平淡为生动,加强语气,使评卷老师感受作者的强烈情感。
(倒装句)Only in this way can Internet Bars be well used by people.
(感叹句)I thought,“How hard mum is working! She must be very tired.”
5、巧用排山倒海句
如能运用一个个排比句、对偶句、不定式或短语,可令文章增色不少,会给评卷员眼前一亮的感觉。如:
The purpose of the program are to make our school more beautiful,to make the air cleaner and fresher,and to turn our school into a better place for us to study and live in.
三、谋篇方面:结构要清晰而流畅,巧用过渡词
众所周知,语言的最高层次不是传统语法所说的句子,而是语篇。语篇指的是一系列连接的语段或句子构成的语言整体。一篇好的文章不但句子正确,要点齐全,更重要的是有效地使用了语句间的连接成分。因此,恰当使用好连接性的词语和句子,是使作文获得高分的一个重要因素。
下列各组表示列举或补充的短语或句式非常实用,对高考写作很有帮助:
(1)Firstly...,secondly...,thirdly...,finally...
(2)In the first place...,in the second place...,in the third place...,lastly...
(3)to begin with...,then...,furthermore...,finally...
(4)to start with...,next...,in addition...,finally...
(5)first and foremost...,besides...,last but not least...
(6)most important of all...,moreover...,finally...
如果只有两层意思,可选用下列两组中的任一组:
(1)On the one hand...,on the other hand...
(2)For one thing..., and for another thing...技巧,希望对大家有帮助

+ 加入清单Seeing mywhole education history, I have many teachers. But my favorite teacher is onlyone. He is Mr Lu. He is my middle Chinese teacher and head teacher. He is aboutfifty years old. Maybe he works too hard, so his back is a little bent.

纵观我整个受教育史,我有过很多老师。但我最喜欢的老师只有一个。他是陆老师。
他是我的初中语文老师兼班主任。他大约五十岁。也许是因为工作辛苦,所以他的背有点弯了。
他总是戴一副黑色的眼镜。他看上去很和蔼可亲,对学习却是很严格的。他总是把我们放在第一位。
他的课是非常有趣的,也经常讲各种不同励志故事。他对我们学习很严格。但无论谁有困难,他都会毫不犹豫地帮助我们。有时他是一个严格的老师,有时候他是一个慈祥的父亲。
篇11:写网络的高中

+ 加入清单科技在发展,时代在进。21世纪,网络已成为家家户户生活中的一个部分。
忘记了初次接触网络和电脑是在什么时候,貌似是在小学二年级的暑假吧!那次,吴佳雨家玩,初次接触到了电脑。
后来开学后,学校也开设了电脑课。
在我小学四年级的时候,爸爸也给我们家买了电脑。由于父母管得比较严,我只能在网上查找一些资料,玩儿游戏那是想都别想。
不过,这种情况也有例外。
记得那年寒假,在一个“北风呼啸雪纷飞”的大年三十,我们要回乡下吃团圆饭,但那时候,我们只有一辆摩托车,根本坐不起我们四个人。来把老妈商量过后决定——他们俩带着妹妹回家过年,而我则一个人留在崇福,并特许我可以玩电脑。
爸妈走后,我转身就打开了电脑,登上QQ,然后一边和同学聊天,一边玩小游戏。但是,我一向都是三分钟热情,玩了没一会儿,就觉得没意思了。
关了游戏和QQ,我便坐在电脑前感到无所事事,但又不想放弃这个机会,就呆呆地坐在那里——就像是一个被饿了好几天的人,突然有了一大堆的食材却不懂得如何烹饪一样。
想了好久,我才想到了看电视这回事,便打开了迅雷……
现在想起来,那是的我还真是笨的可以,面对一台电脑,竟会觉得无事可做。
初一开始,我便在电脑上看书,记得我看的第一本书是沈石溪的《狼王梦》
俗话说:网络是一把双刃剑,在成为我们生活中的一部分时,网络也在不断地危害很多中小学生的身心健康,愿网络能够给我们带来更多的好处!

Therefore, it’s extremely important for students to stay far from computer games.
篇13:网络危害英语
全文共 1476 字
+ 加入清单Nowadays, there is a widespread debate about the influence of the Internet upon peoples life. Undoubtedly, there are both advantages and disadvantages in the Internet.
Generally speaking, it is widely believed there are two major positive aspects of the Internet as follows. Firstly, the Internet has provided us with easy access to the necessary information and materials we want for living, learning and entertament. And secondly, the Internet has promoted greatly the efficiency of our daily affairs such as shopping and communicating, saving us a lot of time, energy and money.
However, as a popular saying goes, every coin has two sides, and the Internet is no exception. The negative aspects of the Internet are also quite apparent. To begin with, the comfort and convenience we get from the Internet is gradually making us lazy and depend too much on it. In addition, the Internet is a fertile soil where many dishonest people are born and grow.
To sum up, we should try to bring the advantages of the Internet into full play, and reduce the disadvantages to the minimum at the same time. In that case, We will definitely make a better use of the Internet .
如今,人们就网络对我们生活的影响展开了广泛的讨论。确实,网络就是一个利弊兼有的东西。
总的来说,大家普遍认为网络有如下两个主要优势。第一,网络让我们便捷地得到我们在生活、学习和娱乐中所需要的一些必要的信息和素材。第二,网络大大提高了我们日常生活的效率,比如购物和交流,为我们节省了很多的时间,精力和金钱。
当然,正如俗话说得好,每一个事物都有两面,网络也不例外。网络的弊端也是非常明显的。首先,我们从网络使用中享受到的舒服和方便让我们变得更加懒惰,进而对网络产生了太多的依赖。另外,网络也滋生了社会中的骗子,给他们提供了良好的生存土壤。
总之,我们应该尽力发挥网络的“利”,同时尽量去减少网络的“弊”。这样一来,我们就能更好地利用网络。

目前,一些诸如GG、MM、 Xia Mi 等网络语言在青少年中极为盛行,并且出现在家庭作业报告,甚至全国入学考试的作文中。请你以 “Should Internet Slang Be Prohibited (禁止)?”为题,根据下表内容用英语写一篇短文,并谈谈你自己的看法。
注意:
1. 短文开头已经给出,不计入总词数; 2. 词数:100-120左右
Should Internet Slang Be Prohibited?
At present, Internet Slang, such as “GG, MM, Xia Mi”, has become popular among the teenagers.
There are different opinions on Internet Slang. Some students think Internet Slang is vivid, fashionable and full of humor and intelligence. Besides, it makes chatting on the Internet quicker.
However, some other students think Internet Slang lacks depth of thought and is too simple. Also, it is hard to understand and not accepted by most people. The words sometimes might make people confused, even resulting in misunderstanding.
Every coin has two sides. In my opinion, living in the Information Age, if we don’t know the Internet Slang, we seem to fall behind the times. It will be OK as long as these terms are used correctly in proper situations.
【参考译文】
应该禁止网络语言吗?
目前,网络俚语,如“GG,MM,夏咪”,在青少年中已经流行起来。
关于网络俚语有不同的看法。一些学生认为网络俚语生动,时尚,充满幽默和智慧。此外,它使上网聊天更快。
然而,另一些学生认为网络俚语缺乏思想深度,过于简单。此外,它是很难理解和不被大多数人接受。这些话有时会使人迷惑,甚至造成误解。
每件事情都有两面性。在我看来,生活在信息时代,如果我们不知道互联网俚语,我们似乎落后于时代。只要这些术语在适当的场合正确使用,就可以了。
篇15:保护海洋高中英语作文
全文共 2299 字
+ 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.

+ 加入清单对于小长假,我总是“又爱又恨”。高兴的是我可以出门旅行游玩,郁闷的是一周只上一次的国学课不得不请假。但自从妈妈给我报了网络课之后,这个矛盾就解决啦!这不,今年清明节假期又到了,妈妈带我去浙江金华旅行。白天,我开心地游览了叶圣陶老先生笔下的双龙洞,晚上,回到酒店打开电脑,连上网络,完成了国学课的学习。
其实,第一次妈妈告诉我可以通过网络上课的时候,我还心存疑虑:没有老师,没有教室,没有同学,仅凭一台连上网络的小小电脑,就能上课?但一打开电脑进入网校软件,我就被老师风趣的语言和深入浅出的讲解牢牢吸引住了。不明白的地方可以随时停下发问,在线的助教也是有问必答,方便极了!那堂课我听得格外认真,讲解结束后我还在线上完成了随堂测验,结果显示我完全掌握了知识点,这效果一点儿也不比面授课差。网络课既节约时间,又提高效率,让我享受了一次旅游学习两不耽误的美好假期。
网络带给人们的好处数不胜数,比如,外婆现在不用去菜场买菜了,只要用手机在软件“朴朴”上一点,新鲜蔬菜就能送到家;外公不用出门买报纸了,打开手机就可以浏览到世界各地的新闻;妈妈带我逛街时,我也不用提醒她带钱包了,因为大到商场、连锁超市,小到路边摆摊的商贩都能直接用手机进行支付。
但是网络也存在一些弊端,比如,网络游戏容易让人沉迷,无法自拔;长时间地盯着屏幕,容易造成近视。
作为网络时代下出生的“零零后”,我们一定要正确使用网络,保护好眼睛,避免沉迷游戏,同时认真学习计算机知识,未来让互联网更好地造福人类。

有一次,孩子问我有关写景状物的作文怎么写,我绞尽脑汁也想不出来。中午回来,呆呆地坐在电脑前面,突然,收到同学的一封邮件,我灵机一动,应该找这位高人帮忙呀!我迅速打开网页,手指轻轻点击,一篇篇有关写景状物的作文尽收眼底。其中,还有名师讲解,精简点评。慢慢地,我对写景状物的作文的写法有了大概的了解,就是以某一景物,某一物体来描写的,在写作过程中,别忘了带上我们的思想情感。我拿起笔,不假思索地一挥而就写完,读了几遍,感觉不是很好,我不如发到网上去,让全国各地的同学都来帮我修改。说干就干,不一会儿,我收到各种各样的点评,“结构不严谨,如果在结尾处,与第一段呼应,那就完美了”。“如果把景物写得美一点就更好了,那你的作文肯定是最美丽,给人一种,美丽的心情”。我收到这篇评论,心里感到舒服多了。收到这么多的宝贵的意见,我又重新写了一篇,指导孩子后,他非常满意。后来交到了老师那里,果然受到了老师的好评。从此,我喜欢上了“网络作文”,有空就打开网页,寻找这些高人。
当然,任何事情都有他的另一面,网络作文也不例外,很多学生成了“网虫”,遇到问题自己不动脑筋思考,总是依赖网络甚至有抄袭的现象,这需要家长及时地安排、监督。
总之,网络作文利大于弊,我们要取长避短,好好尊重这位神秘高人,让孩子要多在网上写作文,这样,既可以提高孩子的写作水平,又可以帮助我们解决一切困难。我很喜欢这位高人,你喜欢吗?快上网了解我们这位高人吧,它会给我们生活带来乐趣的。
