2、80 字左右为宜，字数不足会被扣分。Task 1中G 类内容为书信，出现较多的为投诉信、申请信、道歉信、介绍信、感谢信、询问信、确认信等。A 类则以考核图表为主，常见的有：曲线图(line chart/graph)、柱状图(bar chart)、饼状图(pie chart)、表格(table)和流程图(flow chart)等。Task ObjectiveTask 2中，A 类和G 类很相似，要求考生在40分钟内完成字数不能少于250字的作文，如果字数低于250将会被扣分。题型一般为三大类：1.对某个观点发表支持或反驳意见。2.讨论针锋相对的一组观点。3.解释某种问题出现的原因，并提出相应的解

3、决办法。Task Preparation 评分标准解读写作任务完成情况(Task Achievement)连贯与衔接(Coherence&Cohesion)词汇丰富程度(Lexical Resource)语法多样性及准确性(Grammar Range&Accuracy)写作任务完成情况(Task Achievement)考生要就各部分写作任务中的问题充分展开观点，并提出相关的、得以充分延伸的以及论据充分的论点。在准确地找到信息中关键的内容后，对其进行描述和写作。连贯与衔接(Coherence&Cohesion)连贯(which refers to the linking of ideas th

4、rough logical sequencing)指思维逻辑，它是表达的基础，另外，它还体现在分段上，既包括段落之间的排列也包括如何切分段落。衔接(which refers to the varied and appropriate use of cohesive devices to assist in making the conceptual and referential relationships between and within sentences)指逻辑手段，包括连接词、代词、句子副词三种。逻辑手段的使用要自然，避免使用不足和过度使用。词汇丰富程度(Lexical Resou

5、rce)词汇的评分点包括广度(range)、难度(sophistication)和准确度(accuracy)三个方面。尽管考生很重视词汇，但存在着认识上的误区。所谓的难词并不是只有查阅牛津高阶英语词典才能认识的词。例如，满分作文里出现的难词有：innate,differentiate,inherit,facility,mutually 等都比较简单，考生要把精力放在加强词汇的准确度上来，提高正确运用能力。语法多样性及准确性(Grammar Range&Accuracy)语 法 多 样 性 及 准 确 性 的 评 分 点 也 包 括 广 度(r a n g e)、难 度(sophisticati

6、on)和准确度(accuracy)三个方面。使用复杂句的目的是为了用一句话包含更多的意思，而不是为了复杂而复杂。所以考生要避免把一个简单的意思写得很晦涩，同时还要注意句型广度的变化。准确度指语法正确，包括单复数、时态、介词的使用等方面。小作文A A 类A 类作文要做到：1.客观地描述图形信息；2.进行比较和对比；3.对非个人性的话题提供报告，不掺杂个人意见；4.使用图形描述语言。1.1.线形图一般包括以下三段：第一段、引言首先给图形下定义，即日期、地点、图形讲述的具体内容。接着要总结出图形的总体趋势。第二段、主体对图形的总体趋势进行描述。描写顺序要结构合理，逻辑清楚。第三段、结束句用一两句话概

7、括图形内容，得出一个相关结论。此类图形要描述的要点是：1.总体趋势；2.起始点数据；3.终点数据；4.同一区间数据相似或不同之处；5.交叉点。Sample 1Sample 1You should spend about 20 minutes on this task.The graph below shows the consumption of fish and different kinds of meat in a European country between 1979 and 2004.Summarize the information by selecting and repor
