(A)在任务完成方面，达到写作任务各项要求、能确切选择有用信息进行全面评述、呈现并强调主要特点或要点，但细节可能与要点无关、不恰当或不准确。

(B)连贯及衔接方面，信息和分论点安排连贯，论证过程清楚，有效使用衔接手段，但句内或句间衔接有错误或显机械呆板，有时指代不清晰或不恰当。

(C)词汇量方面，相对写作任务而言，所运用的词汇量充足，尝试运用非常见词汇但有时出现错误，拼写和构词出现一些错误，但不影响交流。

(D)句式多样性及语法准确性方面，混合使用简单和复合句，语法和标点出现一些错误但基本不影响交流。

一、状语前置

所谓状语前置就是把状语（副词，介词短语，分词，不定式）放到句首。这种句式通过一堆长句子中出现一个小短语，可以让句子产生长短结合的紧凑感，实例如下：

1）Unfortunately, professionals from other fields who make a much greater contributions to human society, are paid so much less that it is hard to disagree with the statement.

2）Obviously, education systems are based on the belief that all children can effectively be taught to acquire different skills.

 二、句中插入短语

和状语前置类似，长句子中间插入一个小短语，可以让句子读起来更轻松灵活。考官实例如下：

1）This will affect the job market, which, after all, is a key target in any economic plan.

2）Sports stars and pop stars,for example, are soon replaced by the neat younger, more energetic generation.

三、倒装句

这种语法现象考生都学过，但往往在作文中忘记或没有意识使用。先看两个例子：

1.Parents should spend time on their children. They should also communicate with them.2.We can never lose sight of the significance of education.这两个句子没有任何错误，但都很单调平淡，如果使用倒装，效果就不一样了。

 四、强调句

强调句的句式框架结构为It is+（被强调的成分） that/who+（句子剩余成分）, 类似于中文的“正是…导致了…”的意思。例如，考官范文中的例句：

1.It is the interaction of the two that shapes a person’ personality and dictates how that personality develops.

2.It is only those who reach the very top of their profession who can get these huge salaries.

强调句式是考生比较难把握的一种句型，容易和it引导的形式主语相混淆，其实我们可以通过去掉It is… that…/It is…who…的框架看剩下的是否是一个完整的句子来判断强调句写的是否正确。

考生可以以通过以上几种句式结构的介绍，搭配简单句去使用，让句式灵活多变。例如：“二十世纪末科技的繁荣，人们开始广泛使用电脑”这句话可以分别用以上介绍的句式结构来变化表达法，使句子做到丰富多变，不再单一重复：

1）witness 句型

The late 20th century witnessed the prosperity in science and technology, thus giving rise to the wide application of computers.

2) With 结构状语前置

With the prosperity in science and technology in the late 20th century, computers were widely applied.

3) 倒装句

So flourishing was the science and technology in the late 20th century that computers were widely applied in various fronts.

4) 强调句

It was the prosperity in science and technology in the late 20th century that gave rise to the wide application of computers.

五、平行结构

严格来讲，平行结构并不属于特殊句式，而是英语语法的规范要求，但是由于遵守这个基本语法规则的中国考生太少了，平行结构也升级成了一种“特殊句式”。这种结构的使用在考官范文里出现较多，最常见的形式是在表示并列关系的连接词，例如 and/or等的前后两侧用名词对名词，形容词对形容词，动词不定式对动词不定式，分词短语对分词短语，从句对从句…比如：

1）Satisfaction is also increased by a sense of responsibility for and loyal to a team.

2） Even when children use a computer for other purposes, such as getting information or emailing friends, it is no substitute for human interaction.

以上就是雅思写作通常可以涉及到的经典高分句式，但值得注意的是各种复杂句式并不是高分的标准，对文章的整体把握，合理运用各种句型，保证文章的逻辑以及流畅性才是最主要的。

当然语法结构正确也是必不可少的评分标准之一！同学们在备考写作是应当注意这一点，避免重度使用复杂句式而忽略了文中提到的其他评分点。
