1.引言
雅思考试（ielts - international english language testing system）是听说读写四项英语交流能力的语言测试。作为英联邦国家的主要认证考试，雅思考试已经成为中国学生留学的必要环节。然而，中国学生的雅思成绩却不十分理想，尤其是在写作方面，满分9分，中国考生的平均分在5分左右，位居世界倒数，严重影响了出国学子留学申请及深造的成功录取率。雅思的授课老师和学生都在写作方面投入了不少时间和精力，可是结果仍然不尽如人意。根据观察，从事雅思教学的教师多为英语培训机构的教职人员，不少老师对考试的特点了解不够，对学生在写作中存在的问题尚缺乏研究对策和科学的剖析。
通常，在经过一定训练后，大部分考生都能完成雅思考试的基
雅思饼图小作文的高频词汇表达
雅思饼图小作文的高频词汇表达 雅思小作文是雅思作文中很多考生认为相对比较轻松的一项，但是还有相当一部分考生在这方面得分不佳，主要是一些表达非常的不专业，在词汇选择上存在很大的问题，其实这个问题并不大，天道小编觉得掌握一些基本的雅思作文词汇表达可以解决这些问题。 由于雅思小作文饼图主要以比例说明和数字列举为主，我们需要在考前准备好以下模板： ① 动词“占”的表达： account for, hold, make up, take up, constitute, comprise, represent ② 百分比的表达 percentage，proportion, share, 某些情况下可以用rate，如literacy rate ③ 约数表达 the majority of, most of, a considerable number of, a minority of , just over…, slightly more than…/less than…, nearly half… 等 ④ 确切数字表达 分数与百分比的转化：one third, two fifths，one tenth 常见表达：a quarter, a half ⑤ 句式 要灵活运用以上的词汇结合一定的句子，变换表达方式。 例：亚洲人口占世界比例近50%。 — Asia accounts for almost a half of world population. — Nearly 50% of people in the world come from Asia. — The percentage of Asian in the world population is slightly less than a half. — Asia has the largest percentage of population in the world( approximately 50%). ⑥ 排序段 在列举饼图数据时，为了防止单调枯燥，我们常常运用排序的方式进行说明，所以下面的关于排序的模板也是大家需要记忆的：
雅思写作语料库--人们如何保障饮食健康
Scientists believe that eating fast food is harmful to one’s health. Some people think that education can help them change that bad habit. Others, however, argue that education does not work.Discuss both these views and give your own opinion. 科学家认为吃快餐有害健康，有人认为教育可以帮助人们改变这个不良习惯，有人认为教育不起作用，讨论两种观点。(2010年12月11日雅思考试题目) 【名师点评】讨论两种观点，可以使用第一人称口吻，也可以使用第三人称口吻。【作家立场】保障健康饮食，教育是起到一定的积极作用，但是，健康饮食不能仅仅依靠教育。 【思路拓展】 ①青少年是快餐的主要消费者，快餐含有过多的糖分、脂肪、热量，长期食用有害健康。所以，青少年应该成为教育的主体。 ②为了减少快餐对于消费者的不良影响，除了教育以外，政府也该承担责任。例如，美国政府已经限制肯德基捆绑销售儿童套餐的商业行为。 【范文赏析】 【首段】背景介绍+ 作家立场 So prevailing are the fast foods that some teenagers are in the habit eating junk foods nearly every week. From the perspective of some
nutritionists, too much intake of sugar, calorie and fat is undoubtedly health-threatening, for fast food, in most cases, is low in nutritional value. People differ greatly in their views as to how to foster wholesome dietary habit. As I see it, educating the public about the dangers of unhealthy eating, regulating baneful sales and food advertisements to children and lowering the price of healthy foods should be used together to help people keep fit. 【二段】 Granted, one effective way to promote a healthy diet is to educate people about the potential risks of unhealthy diet. Modern people might opt for healthier meals and snacks if they are taught that fast foods are high in salt, fat and sugar. To illustrate, I myself changed my unwholesome eating habits after watching television programs on how to preserve health. Also, while it is of great significance to educate adult eater, schoolchildren should be main target for education because they are not only in their formative years but also the regular eaters of fast foods. 【三段】 In addition to education, other ways to promote healthy eating are not far to seek. First, methods should be adopted to strictly censor those

【16-25天】18个高频雅思写作话题思路分析与素材汇总
最近考试高频的十八个写作话题思路分析与素材汇总！只有7页，共18个话题，中英双语结合给出了关键思路和素材，给出了关键的高分词汇与表达！老是在考试时理不清思路、想不出素材的同学，看了一定会有帮助的！大家加油加油！ ----------------------------------------------我是分割线--------------------------------------------------- 一、跳槽的原因及解决办法 1、相关词汇： fierce competition heavy pressure job-hopping is looked upon to move upward quickly keep skill fresh and up to date acclimatize themselves to the rapidly changing society 2、原因： （1）社会压力大，人们的竞争意识增强，不断改变以适应社会的变化。 （2）处于个人发展的需要，寻求升职，更新知识。 （3）金钱的诱惑，不在乎在哪儿工作，做什么职业，只要挣钱多。 （4）家庭原因，spouse工作地点改变或孩子去其他地方上学。 3、解决方法： （1）要理性看待，一般来说，stability equals success。
（2）chronic job-hopper将被questioned integrity and loyalty ，not reliable。 （3）政府和mass media应该鼓励人们扎根一个地方，扎扎实实干事业，并且尽可能提高welfare，改善城市和community的环境，留住人才。 （4）公司应该提高工资待遇，给employee创造一个良好的工作环境，在保证企业利润的同时要考虑员工个人发展，增加培训，扩充员工的知识。 二、大学是否应该根据就业教授学生知识，大学的主要功能是什么 平衡写： 1、认为应该提供实际知识的： （1）大学生毕业就要找工作，因此要培养学生掌握future job的技能。 （2）有人甚至声称理论没用，不是每个大学生都要做科学家。 2、反对方： （1）It will definitely be shortsighted to…目光短浅理论知识非常重要，理论指导实践，大学的职责不仅是教会学生一门技术，更重要的是教授一种方法。 （2）不学理论只学实际知识，会使学生变成utilitarian，narrow-minded，lack of imagination，如果学生要学的只是生存的技能，那就去vocational school。 3、总结 总之，我认为大学的功能是versatile的，促进学生all-around development，培养学生具有creative mind in some special field，而不只是教授该领域的实际知识，可以通过一些part-time job来获得。 三、个人不能对环境保护做不了什么，同意不同意 This is just an excuse for the ignorance of environmental protection. 1、分析环境恶化原因是缺乏环保意识。 2、给出解决办法。 四、维持博物馆是否是浪费金钱？ 1、提出自己的观点（反对）。 政府应该spend a lot of money to enrich the collection of museums to cater for different tastes or needs of different people．有的人认为是浪费钱，我认为是很有必要的。 2、博物馆很重要（博物馆的作用）。 （1）illuminate the culture，history and arts of the world. 比如，世界上最大的British Museum provide visitors with all-round knowledge about the world culture and arts,collections in it trace the development of civilization throughout the history of mankind. Definitely a heartquake！ （2）shoulder the responsibility to preserve and carry forward a country‘s traditional culture. （3）serve as a significant mean of adolescent education,benefit both the present and future generation. 教育学生什么是美，purify their heart，也可以作为第二课堂，提供教学参考

雅思写作常用连接词2
在雅思写作的四大评分标准当中，连贯性与衔接性是其中的一项评分标准，连贯性与衔接性其中一方面就是用连接手段（即连接词）来实现的。连接词本身是非常繁琐的知识，在教授连接词时也会遇到很多困难，那么学连接词首先把连接词词性掌握并掌握各词性的用法，学连接词就简便得多。朗阁海外考试研究中心分析认为，连接词大体可分为四种词性：连词，副词，介词和短语，它们各自的用法又不一样。 连词 如but, and,后接句子，连接并列句时前面逗号可有可无。当然连词也可放句首，这一点在考官范文里有很多体现。 例：In the past, populations were partly regulated by frequent war and widespread disease, but in recent years the effects of those factors have been diminished. (并列句中的连词) 段落开始：But how should it be achieved ( 连词放句首) 介词 如before, despite：后接名词或动名词 例：Before talking about the essential role of death penalty, you have to think about the meaning, and the purpose, of any kind of punishment. 副词 副词连接并列句，前面用句号或分号，后面用逗号（当然，如果副词前用句号，那就是另起一句了，不称之为并列句） 例：In many places today, children start primary school at around the age of six or seven. However, because it is more likely now that both parents work, there is little opportunities for children to stay in their own home up to that age.( 副词另起一句) The crime rate is increasingly high; therefore, the government needs to enforce more laws to curb this situation. ( 副词在并列句中) 短语 如on the contrary, in addition：用法和副词用法完全一样 例：They feel this is one area of life where they have the right to make decisions for themselves. For that reason, it would seem that the best approach would be work by persuasion rather than compulsion. The government plays a crucial role in scientific research; on the other hand, private companies hold certain advantages in conducting scientific research. ( 短语在并列句中) 掌握连接词的四大词性及用法以后，连接词的教学和运用就容易展开。我们可以参看考官范文，看看各类关系的时候考官如何使用连接词，使文章凸显出来。 因果关系 根据词性及用法可归结于: because / since/ as / for, so (连词), because of/ due to / owing to/ as a result of (介词) for that reason/as a result/ therefore/ accordingly (短语和副词) 例：I think the amount of waste produced is also as a result of our tendency to use sth once and throw it away. （可代替词汇because of/ due to / owing to）

雅思写作语料库--小组学习和自己学习

Which way is more effective? 有人认为学生们应该小组学习，有人认为学生们应该自己学习，小组学习和自己学习利好各在哪里，你认为何种方式有效? 【思路拓展】 小组学习的利好： 1. 小组讨论，集思广益，例证展开：小组讨论数学题的解题思路，小组讨论作文的头脑风暴。 2. 有良好的学习氛围，可以帮助缺乏自律性的孩子们专注于学习，提高学习效率。 3. 有效的方式结实新朋友，锻炼人的口才，交流能力以及团队精神。 自己学习的利好： 1. 培养了自己的独立思考以及解决问题的能力，学习上不会对他人产生过度的依赖。 2. 小组学习更加容易培养人的分析性思维，理性思维和辩证思维的能力。 点评：论据支持可以学习历史和哲学，以及中学生学习国际新闻 【作者立场】
