雅思考试应该先写小作文还是先写大作文

第一篇：雅思考试应该先写小作文还是先写大作文

考生在雅思写作考试时有两种常见写作顺序。一种是先写大作文，另一种是先写小作文。到底哪一种更为可取呢？ 如果先写大作文的话，由于大作文在写作中得分的比重大，所以可以先攻克难关，有充分的时间来写大作文，可以避免由于花过多时间在小作文上而导致大作文写不完的情形。但如果大作文的时间花得太长了，小作文没写好的话，也是很可惜的。而且，考生在刚提笔写作的时候，通常需要一段时间来进入写作状态，这样一来，大作文的前半部分可能写得就会不如人意。反之，如果先写小作文，虽然可能有大作文还等在后面的心理压力，但好处更多。首先，小作文比较简单，套话多，结构容易，表达法也更加固定，所以写起来比较顺利，可以增强自信心。其次，进入写作状态是需要时间的，先写小作文可以让自己的笔头越写越顺，等到20分钟后开始写大作文的时候，正好进入最佳状态，来面对大作文。总之，我个人认为，还是先写小作文，然后再写大作文更为可取。当然，如果考生习惯了先写大作文的话，也是完全可以按照自己的步调来进行的。但无论先写大作文还是小作文，都需要分配好时间，那就是小作文20分钟左右，大作文40分钟左右。附：以上的回答我是故意按照雅思“分析利弊”的写作套路来写的。大家可以琢磨琢磨：）

第二篇：基于“先写后教”的微型作文教学

基于“先写后教”的微型作文教学

【摘 要】

作文，不仅仅是人们用来进行社会交际和思想交流的重要手段，更是社会衡量一个文化人的价值的重要标准。作文一直是学生迈不过去的“坎”，更是语文教师的“痛”。多少年来，语文教育的改革者发起了一次又一次的作文改革的实验。学生写作的实际情况结合当今时代的发展，随着网络技术的飞速发展，日益加快的生活节奏需要人们在众多信息中挑选出有价值的信息，捕捉瞬间的灵感，为了满足人们快捷的阅读需求和表达自我的心理，微写作应运而生。虽然“微写作”这个词是由微博兴起的，但是在作文教学中并不算是新事物，小作文、微读微写、片段作文等都是我们所熟知的微型写作的训练形式。那么如何有效地进行二者的结合，值得我们去进一步探究，笔者尝试创新出更新的作文教学改革方式。

【关键词】

作文教学 微型作文 “先写后教”理念

一、核心理念的定义

1.微型作文写作

微型作文改变以往作文教学的形式，将微型作文写作方法与学生的实际情况进行结合。微型写作以其篇幅短小精悍，语言简洁凝练，字数控制在二百字以内，通过字数体现了“微”的特点。相对于常规的作文来说，微作文的字数并不是一个僵化的数字，而是灵活可变的，多则二三百字，少则一两句话，都可以看作是微写作。微写作的主题明确，内容丰富。与大作文相比，微作文的主题更加明确单纯，具有很强的针对性，相对于以往的常规作文来说，有利于引导学生用简洁凝练的语文表达个人的观点，加强对身边问题的关注。

2.“先写后教”的理念

“先写后教”的理念倡导以学生为主体，呼吁回归写作的本源。作文教学的起点应该在哪里？那一定是回归学生写作的实际。语文课标指出：作文教学是学生真实情感的表达。那么，我们只有回归本源，基于学生的实际情况，才可以使学生更好地进行情感的表达。

二、基于“先写后教”的微型作文教学的重要意义

1.树立大的语文教育观，将写作回归生活

语文的外延与生活的外延是相等的。生活即写作，写作即生活，基于学生实际情况的微写作与传统的大写作相比主要的不同点在于：一方面有利于学生真实情感的表达，另一个方面有利于学生更好地进行有效的作文写作，提升学生的阅读兴趣。

2.促进了写作教学与时代的接轨

随着社会生活以及现代科技的发展，我们的生活方式也逐渐高效率、快节奏化，在这种大环境下微写作成为人们表达自我最喜闻乐见的形式，随时随地记录生活中的点滴成为一种时尚，这种变化也渐渐影响着学生们的写作习惯。当写作与微博、微信等自媒体手段相融合时，我们也就看到了语文写作教学与时代的接轨，微写作的发展便是语文写作教学不断进步的体现。因此，我们有效的借用这种方式可以更好的引导学生进行自身的情感表达，有利于冲出作文的瓶颈。

二、基于“先写后教”的微型作文教学的相关策略

1.借助微博、qq等网络媒介，培养学生写作兴趣

互联网是一把双刃剑，我们可以利用互联网的优势，鼓励学生进行作文的写作。借助微博、qq等新时代的社交媒介记录自己的生活。我们在借助新型社交媒介鼓励学生进行微型写作，我们要适当的引导学生恰当的利用互联网、适当渗透习作的谋局布篇的写作技巧和方法，进而将自己生活的所感所闻记录下来。

2.落实生活化原则

新课标指出：写作教学要贴近学生的生活实际，让学生易于动笔，乐于表达，引导学生关注身边的人与事，关注现实，热爱生活，积极向上。作文教学为什么一直以来是学生心理的痛，教师迈不过去的坎。很多学生苦于作文，难寻作文题材，不知道写什么，这实际上是对生活缺乏了观察和体味。教师可以适当的引导学生学会用互联网去记录自己的生活，将自己的真实感受记录下来，唤醒?W生内心的情感，呼吁学生回归生活，真正地体会生活。

3.确定适当的微型写作主题

设定满足学生兴趣的写作主题。微写作具有目标性，并非胡乱写作，达不到效果，也就是说，微写作要求有一定针对性，有一定的目标和主题，这样才能通过二三百字的训练达到提高写作水平的效果。题目的设定不仅要贴近学生的生活实际，还要能够引起学生的兴趣，引起他们的共鸣，这就需要一定的交际语境，给学生提供一个尽量具体的，让学生有话可以说得情境。例如：学校集中组织学生去进行一次秋游，那么在进行秋游的时候可以鼓励学生将自己的所见所闻借助互联网记录下来，教师适当地给予有效的引导。

4.有效监控，优化微型作文写作

依据学生微型写作的实际情况，根据学生的实际进行有效的引导。我们可以利用学生的微型写作的平台进行多维的评改，进而根据学生的实际情况，对学生进行有效指导，进而根据学生的实际情况，对学生进行有针对的指导。

微写作在不断地发展壮大，不断地系统化和科学化，即便一些地区的高考试卷还未开始尝试，但我们不能忽视其对于写作教学的重要作用，同时作为语文教师，更应该把握好微写作的教学方式，推动语文写作的更好发展。

第三篇：发表英文论文是先写中文再翻译还是直接用英文写

这主要决定于你的英文水平和写论文的水平决定的。本人觉得在写英文文献的过程中大致要经历三个阶段。你处于哪个阶段决定了你采用什么样的方法。

1、绝对新手，尤其是基础差，信心差，有拖延症的新手先写中文稿，再写英文稿是有好处的。对于英文实在差的人，先写中文稿也可以让新手专注于跨越内容和逻辑上的障碍。因为多数新手以中文做为母语，对中文语法，表达和逻辑会更敏感。新手往往会发现即使用中文写作，依然写不出，因为多数新手根本没有真正思考清楚如何分析，描述所要解决的问题。但起码对中文的熟悉可以让新手不至于拘泥于遣词造句上，花半个小时反复折腾两句话里的英文表达。

中英文有不同的表述习惯。一个英文从句往往需要拆成多个中文短句才自然。但逻辑和内容是可以跨越语言的。先写中文稿并不是让新手从中文稿逐句逐词翻译出英文稿。对于很多新手，我是推荐他们一开始用中文写作的。因为这样才能让他们意识到自己写不出的主要原因不是英文不好，而是逻辑和内容没想清楚，是自己没努力(尽管真相很伤自诩逻辑思维能力强的理科生的心)。起码这样可以让新手面对一个复杂任务时可以两步走，降低复杂性。

2、如果你已经读了很多同类的高水平的英文文献，英语水平也有了提升，强烈建议用母语搭建文章主体结构，进一步到具体阐述论证，由于英语与中文表达侧重及语法呈现的巨大差异，则用英文进行写作较妥。

3、如果你想真正写出一篇高水平的文章，最终必须要直接用英文写文章。需要培养英文思维。打底稿翻译失之毫厘，谬以千里，不准确性越来越大。尤其是在成语俗语翻译中更难做到精确。所以想培养英文写作的好习惯，除了平时用心读背之外，还要做到量的积累到质的飞跃。

3.用纳税人的钱修路，改善交通状况

To construct and maintain roads is a public service administered by the government.However,swheresdoes the money come from? Somebody believe that the government should allocate money from national finance on the road construction;but others think that the roads are constructed for people, so every tax-payer has the responsibility for constructing and maintaining the roads.It is so called“What is taken from the people is used in the interests of the people.”

To the first opinion, since government is the administrative organ, it has

responsibility to do overall plan on those public services of city construction, including constructing the road.They think that the government should do plan and allocate every penny on all things concerning people’s life.However in reality, the government cannot do all specific plans and money allocations on every detail concerning the society running.It only has the right of macro-adjustment and control.To be specific on the road construction, many people believe that based on the principle above, since the road is constructed for the

convenience of people themselves, every tax-payer has duty to devote a little on the road construction, which is not only for the city overall plan, but also for their own use fundamentally.Once the constructions finish, the roads will be wider and longer, the facilities along the roads will be better in use, by then people could further improve their working efficiency, etc..As I know, the second opinion is more reasonable and feasible, because it has two advantages: 1.The government could reduce heavy burdens, simplify and make clear the usage of money;2.Tax-payers are clear about the usage of money they turn over, thus improve the transparency.Therefore, it is a good measure for both sides to allocate money from the tax paid by people on the road construction.4.遗失信----财物遗失在民航班机上,写信给机场海关请求帮助

5.有人给学校捐款，建议如何使用。

Dear President, November 11, 1999

I'm very happy to hear that a famous author has donated considerable money to our institute.And I think we could use it to establish an education fund to aid our teachers to study abroad.Firstly, teachers could increase their teaching level and enrich their knowledge by studying aboard.For teachers of a language institute, this kind of experience is really necessary.Teachers would consider that as a kind of prize and therefore work harder for that.Secondly, our institute could be benefited from doing that.Since we could provide the overseas-studying chance for our teachers, graduates with high score in the Normal Colleges are more willing to come to our institute.Thirdly, that will help our students.Our last year's survey showed that 65% of our students prefer the language teachers who had overseas-studying experience.In a word, I think that using the donated fund to assist our teachers to study abroad is a good way to promote the healthy development of our institute.Please take good consideration of my advice.Thanks!

Yours sincerely,Livia Liu

8.给小孩零用钱的利与弊(Pocket Money)

With the development of our modern society, people's living conditions become much more comfortable.But along with intense competition, parents have less time to consider children's needs in all-round.One method to solve this ontradiction is to give children some pocket money.Pocket money is useful to children.But whether the children are considerable enough to make correct use of these money.There are two viewpoints about the pocket money.Some people think that giving children pocket money will make them become luxurious.Others think that will not lead to such disadvantage.In my opinion,both of them are partially reasonable.Someone believe that giving children pocket money really has many advantages.With pocket money, children can buy their daily necessities such as pencils, little toys, and snack food they like.It will give children a certain freedom to select what they want, make them aware rules of the equivalent exchange.Since time to parents is very precious, giving pocket money to children help them to save time spent in shopping, but used in busy working and earning money.Others insist that there are undoubtedly some disadvantages in spending pocket money.First, young children do not know how to use pocket money appropriately, they possibly consume all the money to buy expensive merchandise that they like, and then ask for extra money from their parents.Some parents cosset their children, and always give them a large amount of pocket money.Such conditions will make children become more and more prodigal.Second, since adults do not supervise the procedure of shopping, children could probably buy something that is not suitable for their age, such as adult magazines.Judging these two viewpoints above-mentioned, I think that parents should give their children a limited amount of pocket money.There are some preconditions: the amount of pocket money must be finite;the parents should instruct their children how to use the money moderately and what is suitable to them;for a costly merchandise, parents themselves should take children to buy it.With these preconditions, pocket money will do no harm to their children.9.父母是否应该花更多的时间同子女在一起

In China, both of the parents have their jobs.With the development of economy, people tend to pursue high quality living conditions.Most of the parents try their best to offer their children comfortable circumstances, but they seldom have time to stay with their children.In my point of view, no matter how busy they are, they should make the best use of their time to stay with their children.First, the love between children and adults will be improved by spending more time on their children.Children could feel parents' affection through the genial conversation and sharing their pleasure with them.Every time when parents take them to amusement park, help them to prepare their birthday parties, applaud for them when they are competing in the sports meeting, the time they spend with children will become treasure in their memories.Second, children need the direction from their parents.There are some wrong behaviors in our society such as dishonesty, corruption, violence and eroticism and so on.Children have weak resistance in defending this detrimental influence.In this case, parents' instructions seem to be very important to children's growth.Parents should sit down and talk with them about what they should do and should not do.In addition, if parents often spend time in staying with their children, adults' good behaviors will greatly influence their children.Here I do not deny that there are some disadvantages in spending too much time on children.Some parents restrict their children, and give them little freedom to develop their interests.Therefore, I emphasize that parents should educate and instruct their children appropriately in their spare time apart from their busy works.10.你因病住院,写表扬信,表扬医护人员的医德,服务,环境卫生

Dear Sir:

I am a business man from America, and my name is David Smith.Last month it was the first time that I traveled to Beijing for business, signing a contract with a Chinese food company.Unfortunately I got a bad flu and then had a fever.I was sent to your hospital.Because my temperature was nearly 40 degree centigrade, I was asked to be in hospital.I worried about my business and the delay of signing the contact will lead to great losses to my company.However, After the doctors' careful treatment and

nurses' patient care, I was recovered only in 4 days.I completed the negotiation with the food company smoothly and signed the contract on time finally.So I sincerely appreciate all the staffs in your hospital who helped me full-heatedly.I was deeply impressed by the kind doctors and nurses, the pleasant and comfortable environment, and considerate services.I have no relatives and friends in Beijing, but I felt at home in your hospital.I will always remember all those warmhearted persons and your hospital in my heart.Best wishes to you all!

Sincerely yours,David Smith

11.Children learn best by observing the behavior of adults and copying it.The Process of growing up is very complex for children.Among countless factors that influence children's growth, the behavior of adults plays a significant role in shaping children's inclination and character.After the baby is born, the first and the nearest adults are his/her parents.Although the baby is just slur pronunciation, the little baby has started to learn from their parents by observing and copying the adults' talk.This learning environment is important for the babies.There is a special case reported by the press.A baby was abandoned when she was born.A sow fed her as a piglet.When she was about eight years old, some villagers found her, her intelligence was just similar to the two-year old baby and all of her behaviors were looked like a pig.From this case, we know child is a “mirror” which will reflect the behavior of the closet adults.Along with the children's growth, adults will influence them much more, such as logical thinking, making decision, cooperation with others, etc..The behavior of adults can give children both good and bad influence.Most of the behaviors represent adults' inclination.For instance, if media report chiefly on the shadow side of the society, children will easily incline to violence and excessive sex.Therefore, they will be infected with bad mental state.Behavior is a direct and convincing method to teach children.Things are easier said than done.Parents always tell children those principles repeatedly, but most children can not accept it through these boring method.Adults' behavior is the most effective education method to let them observe the whole process of how to deal with the problems.The children will learn from you naturally.Children are like young trees, they need to be carefully irrigated, fertilized and trimmed.Your behavior will be greatly helpful to shape themsintosuseful talents.12.Zoos are sometimes seen as necessary but poor alternative to a natural environment.Is it necessary to keep animals in zoos?

In the modern society, zoos are almost indispensable places in large cities for people to visit.In some large zoos, there are various animals from space to sea, and from primitive invertebrates to advanced and intelligent mammals.In the zoos, all animals, including those rare animals, such as panda, Africa elephant, and North-East tiger, could enjoy good care and protection away from any hurt.However, along with the stronger natural environmental protection consciousness, many people think that to put animalssintossmall cages will change their living instincts, and therefore break the ecological balance.Viewed from the basic relations between animals and human beings, animals should have the equal freedom with human beings.They are all forms of life.Animals have their own living instinct, and it is this instinct that forms the biological chain of the Earth.This relation is called “Ecological Balance” academically.For example, insect-bird-snake.If most birds in a region are killed and lockedsintoscages by human beings, the pests will eat out all crops, and snakes will lose a large part of food(bird)-resources, therefore leading to starvation and death.This opinion sounds ideal theoretically.However in reality, human beings and other animals cannot stay together peacefully on the Earth.Because of human beings' lust for fortune, many valuable animals are killed or sold, especially those endangered species.Therefore, zoos appear as an active way for people to protect those poor animals.First, this is an action not only for animals but also for human being itself.Once the biological chain is broken, human beings will be punished inevitably.Next, zoos can serve a purpose of educating and entertaining people, narrowing the distance between human beings and animals.Last, zoos can be a scientific study center to rescue more endangered spices and make animals better serve people's need.The key point of this topic is freedom or protection.In my opinion, those two aspects can be unified.It is necessary to keep animals in zoos for the purpose of protection, teaching and study.Let's think it further, the purpose of all these actions is to make animals live happier, therefore, maintain the ecological balance, hence protect our own living environment.
