写好一篇作文的注意事项：
1.适当用被动代替主动，这样能更客观的反映事实, 句子开头不要总是用we / I (比如写结尾时不用we should pay attention to而用Attention should be paid to. )举个经典结尾2004年六月六级作文的最后一段：It is, therefore, high time that some applicable approaches were implemented by the service industry like that. Thus，its competitive edge will be sharpened effectively.
2.善于使用插入语，比如说把副词、连接词等，作插入语放在中间，一般放在主语、动词或者助动词后，两边分别加上逗号。
如however / therefore /for example/I believe 做插入语放在中间，一般放在动词，助动词后，两边分别加上逗号。
比如说：Other individuals, however, take the attitude tha t …
3. 一定要学会换词，换形象，具体的代替太宽泛的。(考试中一般不要出现good, bad , many, thing, think, people, opinion 等等)比如上面例子中，applicable 代替proper, approaches代替ways, implement代替carry out, sharpen one’s competitive edge代替enhance one’s competitiveness(提高某物竞争力) 下面举一篇一位同学写的优秀作文(14分)的例子，看看他是如何运用各类写作技巧的。这位同学把老师上课讲的各类写作手法和精彩替换和句型都用上了，作文有了很大的提高。

Which should be emphasized: knowledge or creativity? Knowledge or creativity, which is primary? So many people have asked the question. According to a recently survey, mere 55% parents think essential knowledge is more important for their children. They point that knowledge is the basic of everything, without which it’s utterly impossible to develop one’s creativity. Besides that, the relationship of knowledge and creativity is input and output. Last but not least, focusing on the basic will make you patient, make you dig out the essential part of things. But opposed to the parents, 85% educators are for that creativity play a vital role in the socialization of children. Frankly, I agree with them more. The fact that we face demand us to emphasize the creativity. Date back to the past, our ancestors made many wonderful achievements. They discovered some math theories hundreds years before western scientists. The reason why we lag behind today lies in we lack of the creativity today. In schools, students are stuffed with piles of knowledge under the pressure of fierce competition. Many young people lose their chances to enter college just because of one early failure in a stupid examination. But practically speaking, how can they show their true abilities? Creativity is the key to a brighter future. Fortunately we have learned the point, and many workable reforms are being carried out. In most schools, students are actively involved in the class activities. For sake of the Chinese children, Creativity is in need.
1环境污染 From the picture above, we can see that people are coughing in the polluted air. With air pollution worsening than before, pm 2.5 has become a usual word for us. Needless to say, people do not like this word, as the content the word represents does great harm to people's health. As the polluted air does affect our health, we should take some measures to make the air cleaner. On the one hand, we should take mass transit（公共交通）instead of driving a car. According to a recent study, vehicle exhaust（汽车废气）is a main source of air pollution, so if vehicle exhaust reduces, the air will become cleaner. On the other hand, more trees should be planted to absorb the tiny dust in the air, which surely will make the air cleaner. Protection of the environment needs constant efforts by every people on the planet. Only in this way can we have cleaner air and more livable environment. 2改编名著 Adaptation Should Not Go Too Far From the Classics In recent years, many classics, especially the Four Great Classical Novels, have been adapted in improper ways. For examples, in a TV series adapted from Journey to the West, Monkey King ridiculously falls in love with an evil spirit（妖精）. It has gone too far from the original version in which the upright Monkey shows no mercy to ant evil spirit. Various reasons account for this phenomenon.Firstly, readers' or audiences' preference plays a critical role. In this market economy, where there is demand, there is supply. So many play writers or directors cater for（迎合）these people's need. Secondly, some producers want to attract people and make profit. To curb this phenomenon, I think two measures should be taken. First, it's necessary to change the way people treat classics. An adapted version that goes too far from the original one is not merely disrespect to the author, but also misleads the readers or the audiences. Second, the concerned authority should check and ban TV series, videos or books that spoof（愚弄）classics. 3手机控 Addiction to Smartphones Do you check your smartphone frequently? Do you feel distracted if your smartphone is not with you? When there’s no wifi or signal for your smartphone, will you get irritated生气? If you say yes, then you’ve got addiction to smartphones.
科技英语写作注意事项 一、文体特点 清晰、准确、精练、严密 1、避免主观渲染，少用带感情色彩的词汇和修辞手段，做到说理叙事清楚明白，用词造句简洁准确，并尽量使用行话，使文章读起来有科技文章的韵味。 2、文章中结论性的表述，必须经过可靠实验性的验证，否则少用肯定性的语言。 二、语言结构特色 1、大量的名词化结构 因为科技问题要求行文简洁、表达客观、内容确切、信息量大；强调存在的事实，而非某一行为。 例：Archimedes first discovered the principle that water is displaced by solid bodies. Archimedes first discovered the principle of displacement of water by solid bodies. 第二句中of displacement of water by solid bodies系名词化结构，一方面简化了同位语从句，另一方面强调displacement这一事实。 由于科技英语所表达的是客观规律，因之尽量避免使用第一、二人称；此外，为使主要信息置于句首。 例：If you use firebricks round the walls of the boiler, the heat loss can be considerably reduced. The heat loss can be considerably reduced by the use of firebricks round the walls of the boiler. 2、广泛使用被动语句 英国利兹大学John Swales统计，科技英语中的谓语至少1/3是被动态。（同上） 3、非限定动词 科技文章要求行文简练、结构紧凑，因此往往使用分词短语代替定语从句或状语从句；使用分词独立结构代替状语从句或并列从句；使用不定式短语代替各种从句；介词+动名词短语代替定语从句或状语从句。这样，即可缩短句子，又比较醒目。 例:Materials which are used for structural purposes are chosen so that they behave elastically in the environmental conditions. Materials to be used for structural purposes are chosen so as to behave elastically in the environmental conditions.
英语写作注意事项 一．如何使句子意义明确 怎样写、写什么样的文章才能得高分呢？这是大家共同关心的问题。下面请大家注意以下几个句子： （1）I get up early，study hard and go to bed late．我早起晚睡，努力学习。 （2）Everything was over．I put my heart into my stomach．一切都结束了。我放心了。 （3）You must make a choice，because you can't eat fish and bear's paw at the same time．你必须做出选择，因为鱼与熊掌不可兼得。 这几个句子都是同学们平时写作练习中出现过的，信手拈来与大家共同探讨。虽然句子结构本身没有毛病，但是属于坏句子。为什么呢？先说句（1），它给人造成的印象很模糊，
泛泛而谈，空洞无物。How early？ How late？How hard？没有交代清楚。这就涉及到写单句（非简单句）的一条原则：具体的原则。能给人留下深刻印象的东西往往是具体的事物，比如说某人想家时会想念家乡的“一草一木”。这“一草一木”就是家乡的“一切的一切”的具体化。同样，要形象地说明自己起早贪黑，刻苦学习的情形，就不能仅仅用两个无法限定准确时间的副词 early和late及无法限定准确程度的副词hard来表示。经提示后，该学生将句（1）改成了：I get up early in the morning，study 8 hours and go to bed late at night。还是不太理想。他想了想再改成：I get up at 5：50 in the morning，study earnestly 8 hours all day and go to bed at 11：00。这样就好多了。 句（2）和句（3）的问题是非英语（Non-English），也就是说这种说法在英语中不存在。由于许多同学写作时往往是用汉语打腹稿，然后逐句译成英语，所以这种“汉化英语”为数不少。解决的办法就是加强词汇积累，同时注意培养英语思维习惯。日积月累，能够改观。 二．句型的灵活运用

商务英语邮件写作的注意事项 1. Write a meaningful subject line 主题要有意义 在把你的邮件发送出去之前，你要检查一下邮件主题是否能够准确概括邮件的正文内容。如果你的主题写得很模糊，或者主题栏是空的话，那么很有可能对方压根就不会打开你的邮件。 我们来看一个例子： Subject: Important! Read Immediately!!! 简评：你认为很重要的事情在别人看来却未必如此，你在邮件主题栏里大喊大叫只会让对方觉得你很傲慢，且不专业。邮件的主题一定要informative (具体;提供有用信息)，让对方在没打开你邮件之前就知道你大概要说什么。上面这个主题可以这样改： Subject: Emergency: All Cars in the Lower Lot Will Be Towed in One Hour 简评：如果你的邮件内容真的很重要且紧急，那么不妨把主题写得具体些，同时，尝试主题首字母大写，这样可以引起对方的重视。 Hi, I m going to miss tomorrow conference, can you send me the conference proceedings? 简评：收到这样一封邮件之后，你肯定很蒙：FuZzYKltTy2000是何许人也?这封邮件可以这样改： To: Bruce Blinderson From: m.****@***.c*m Subject: Conference absence, Sept. 10 Dear Mr. Bruce, This is Morris Ponsybil from
The saying “Knowledge is power” has been well known for hundreds of years, while Bacon was meaning that “Do you want power? Then learn knowledge.” What is knowledge? Knowledge is everything that is known by man through his long experience in the world. Knowledge is the inheritance and development of all the wisdom of the history. The great role of knowledge have shown ever since man appeared on the earth and every period of social development. Nowadays it is a popular view that the prosperity of the country rely on the people's cultural knowledge level of the country. I think this view is reasonable. There are many examples in the history. The government of the Qing Dynasty implemented the seclusion policy, which had brought about serious consequences. In?comparison, the Tang Dynasty had adopted enlightened policies at that time, while culture and science was widespread in the country. As a result, the Tang Dynasty become the most powerful country in the world and the Qing government fell down quickly. The prosperity of a country can't be separate from the knowledge. With the development of our economy, the importance of knowledge is more and more obvious ,especially scientific and technological knowledge. Science and technology are the motive power of the social development. For example, in ancient times thunder and the other natural phenomena have been regarded as acts of god. If there happened to be a drought in the area, what the ancient people can do is praying for god's help. However, now we have the scientific knowledge. With the artificial rainfall approach, crops can be grown still good even in case of severe drought. Man can conquer nature with the knowledge. For thousands of years, human beings have been using their knowledge to improve their life
大学四级英语作文范文（5篇） 【篇一】 Directions: For this part, you are allowed 30 minutes to write a short essay on the topic College Students’Job Hunting. You should write at least 120 words following the outline given below. 1. 近几年出现了大学生就业难的现象 2. 产生这种现象的原因（如大学生追求的目标过高，专业不对口等） 3. 如何解决这一问题（改变就业观念，大学生再培训等） College Students’Job Hunting In recent years, college students find it increasingly difficult to get a job. It sounds strange since young college students are usually intelligent, well-educated phenomenon, aspirant and eager to bring their talent into full play. Then what underlies the strange phenomenon? There are several reasons for this. To begin with, nowadays college students aim too high. All they want are “good”jobs which could offer good salary, comfortable working conditions, high social status among others. Consequently, most college students are unwilling to accept vacant jobs they consider not “good”enough. Another reason is that there is a big gap between the majors some students study in school and the demands of vacant jobs. So companies think some students are not fit for the jobs. Solution to the problem requires efforts on both the society and the students. The companies should value the students, talent and knowledge while the latter should not merely aim at material gains. They should be down-to–earth in building up their career. Furthermore, they should face their weak points so as to improve themselves and be more competent. 点评：本范例题为社会热点话题。近年来大学生就业难日益成为各级政府及社会各方面关注的焦点，媒体也广泛报道了大学生就业形势严峻，呼吁全社会共同努力；此外，该范例题也与大学生就业密切相关，也是四级作文选题重点之一。 【篇二】 Directions: For this part, you are allowed 30 minutes to write a short essay on the topic of traffic jam.

英语写作三大注意事 项
英语写作三大注意事项 1. 尤其在商业上，报章杂志或公文书信上，尽量不用难字 (big word) 或过时 的字眼 (old-fashioned word) 例如： Many people feel that moral education is the infrastructure ofhigher learning. (许多人认为道德教育是高等知识的基础) (如果用 foundation 或 basis 代 替 infrastructure 就更明白) Three hundred acres of land is the parameter of ouruniversity， s expansion (growth). (三百英亩的土地是本大学发展的限度) (如果用limit代 替parameter，会更简单易懂。) This news has been disseminated all over the U.S. (这消息已散布到全美各地) (如果用spread取代disseminated，不更简单？) (动词时态是： spread, spread, spread) The president of this college is not diminutive in size. (这大学的校长个子不小) (假如用small代替diminutive，不更明白吗？) I have to elucidate this document to my staff. (我要向我的员工解释这份文件) (如用explain代替elucidate，也许更明白。) Mr. A will endeavor to be a physician.

英语写作常识 外国有句名言：说能让人变得聪明，写能让人变得严谨。九年义务教育教学大纲对中学毕业生写的要求既明确又突出，写是必备的技能。但对中学生来说，用英语写作是一件很不容易的事，特别是对初学者来说，更是觉得困难重重。为了帮助同学们提高英语写作水平，在中考书面表达题中取得理想成绩，从本期开始，本刊将陆续刊登英语写作知识的辅导与讲座，精彩不容错过哟！ 同学们，写作知识辅导正式开始了，要讲的内容太多了，一时不知从哪儿开始。噢，对了，啥事都有一定之规，那就先说说写作常识吧！ 先说标题吧。 一篇完整的文章通常包括四部分：标题部分、引言部分、扩展部分和结尾部分。标题也叫题目，是文章的有机组成部分。好的标题新颖生动、引人入胜，能激发读者的阅读兴趣，因此对于没有命题的作文对标题要精心锤炼。拟定标题有如下3个要求 1.准确。即要求标题含义和文章内容相吻合，题目意义不宜过宽过泛。题目拟得过宽，写作时便很难抓住要点，容易出现文不对题的毛病。 2.醒目。标题应鲜明、生动地表达文章内容，不落俗套。 3.简练。标题往往只是二三个词构成的词组，而不用完整的句子。而且要做到画龙点睛，言简意赅，用较少的文字表达尽可能多的内容。 标题写法也须注意哟。标题应该放在第一行的中部，和正文之间留有一行或两行的空白。如果标题过长，就把标题写成两行。第二行比第一行短，写在第一行下方的中部。如： an intertesting story about my grandfather and grandmother 标题的第一个字母和重要的单词都用大写开头。介词、连词和冠词通常不算重要的词，一般不大写。但如果标题中介词是五个以上的字母构成的（如through，between，about，among等），这个单词首字母通常要大写。另外尚需注意不能在标题下加横线，标题也不该用引号和括号；即使是完整的一句话，也不用句号，但问号和感叹号可以使用。如： is it an accident？ 好了好了，下面再说说英语字母何时大写？ 1.英语句子第一个词的第一字母要大写。如：my name is li ping. 2.国家、城市、乡、镇等名称的首字母要大写。如：china（中国）shanghai （上海） 3.表示语言、某国人等首字母要大写。如：chinese（中国人，汉语）english （英语） 4.姓名中指姓的词和名的词首字母要大写。如：john smith（约翰。史密斯）wu hongjun（吴洪军） 5.一些专有名词的首字母要大写。如：grade two（二年级），marx（马克思） 6.文章的标题、书名、报刊的名称等，第一个单词及每个实词的第一个字母一般要大写。如：lesson two（第二课），an express way to english 7.表示节日、星期、月份的第一个字母要大写。如：tuesday（星期二），january（一月），children’s day（儿童节）

We assume that the antenna is vertical and that its loss is zero.（我们假设该天线是垂直的，并且其损耗为0）
英语写作注意事项 1、为了保证文章层次分明、条理清楚，要把时间固定下来，如： 记叙一件事要用过去时;写经常发生的事或对人物的描写，要用一般现 在时。整个文章中的人称要一致，首尾呼应，不要随意改动，以免造 成误解。 2、不要为了追求“一鸣惊人”而去找一些生冷的词汇，对这些一 知半解的词你不会用，不知道如何搭配，结果可能适得其反，使文章 显的生硬、不协调，甚至错误百出，所以要使用有把握的词，避免不 必要的失分。比如说发生了一起意外事件，我们通常用“have an accident ”来表示，不要错误的使用“have an incident”。 3、注意不同语言的表达习惯，也是写好英语作文的重要环节，如“我的理想是做一名歌手”，很多同学写成“My ambition is to do/make a singer，” “to do”表示“做”或者“干”，“to make”表示“制作”，而“做一名歌手”则表示“成为一名歌手”应该用 “be/become a singer”;又如“看书、看报”应用“read a book/newspaper”，而不是“see a book/newspaper”。所以，平时 应该注意不同语言的表达习惯，切忌望文生义或一味生搬硬套。 4、有些同学因怕出错而只写短句或简单句，写出的文章过于幼稚、空洞乏味。要使文章有血有肉就要把平时学的知识用进去，如：定语 从句、宾语从句、非谓语动词和比较等句型，关键时用上一、二个， 就能使文章不同凡响，更有文采，特别是对关联词的使用，如“so that”、“not…but ”“not only...but also”等，会使你的文章 逻辑结构紧密、层次鲜明、条理清楚，更能显示出你的英文功底，但 要做到这些并非一日之功，要靠平时的持续训练和积累。 5、最简单的增分点就是认真的书写。工整漂亮的书写会给评卷老 师留下美好的第一印象，在扣分时自然会“手下留情”，而且很多地 区都在写作上有1分的书写分。只要平时多下点功夫，得到这个分并 不难。
