雅思寫作得高分，語法和詞匯功不可沒，如果你能合理的運用語法和詞匯，并且文章對題，那么作文的分數不會低。下面是小編為大家整理收集的關于雅思寫作高分對詞匯和語法的要求，希望對大家有所幫助。
雅思寫作評分標準——詞匯lexical resource
官方給出的7分評分標準：
*uses a sufficient range of vocabulary to allow some flexibility and precision
* uses less common lexical items with some awareness of style and collocation
* may produce occasional errors in word choice, spelling and /or word formation
官方給出的6分評分標準：
*uses an adequate range of vocabulary for the task
*attempts to use less common vocabulary but with some inaccuracy
*makes some errors in spelling and /or word formation, but they do not impede communication
同六分詞匯標準相比，7 分多了兩個要求： flexibility (靈活性) and precision (準確性)。靈活性暗示我們在作文中要設置同意替換詞[1] 。比如，第一段寫了developing countries, 第二段就可以用these nations, 第三段可以用poor regions
準確性 指在該題目下貼切的，核心的詞匯[2] 。比如政府話題寫出welffare 福利一詞，環保話題寫出environmental-friendly 一詞。
7分和6分同時要求：要有less common lexical items, 不普通的，含義較深刻的詞匯。比如undermine ( v. 逐漸破壞)代替damage; 用dilemma 代替problem。用的好不好，地道不地道，是否注意到了style( 文體) 和 collocation (搭配)決定了是6還是7.
所以在寫作中，詞匯在準確使用的基礎上，我們一定要注意設置同意替換詞。在練習時我們就要不斷積累同意替換詞，在經常使用的單詞上多想想，還可以替換什么樣的詞和表達方式。
雅思寫作評分標準——語法grammar range and accuracy
7分評分標準：使用多種多樣的復合句
*use a variety of complex structures
*produces frequent error-free sentences
*has good control of grammar and punctuation but may make a few errors.
(那么什么算是a variety of 呢?3種以上才稱得上 a variety of,所以寫作中要寫出4種以上不同的從句。劍橋書后的考官范文，平均每篇12 句話，2句話是簡單句，2句話是并列句，其余8句都是各種從句)
6分評分標準：簡單句和復合句的混合使用
*uses a mix of simple and complex sentence forms
*makes some errors in grammar and punctuation but they rarely reduce communication
英文句式：簡單句，并列句，限制性定語從句=分詞做定語，非限制性定語從句，名詞性從句(主語從句，賓語從句，表語從句，同位語從句)， 狀語從句=分詞做狀語，強調句，倒裝句，插入語結構， 雙重否定表肯定結構
在寫作中，我們要熟練，正確，恰當的應用多種句式與結構。當然除了句式我們還有時態，準確恰當運用各種時態在簡單句和復合句中。
我們從一些例句中，學習一下語法句式可以如何轉換。
With the rapid development of economy, the environment[3] has been deteriorated[4] . (主+謂的簡單句)
= As the economy develops rapidly, the environment has been deteriorated. (as引導的時間狀語從句)
Experts [5] suggest the government to take down the old buildings in the urban center in order to improve the city image. (主+謂+ 賓+賓補的簡單句)
= Experts suggest that the government should tear down urban old buildings in order to enhance the image of this city. (that引導的賓語從句)
The money which was spent on wild animals protection [6] should have been used to improve human lives . (定語從句)
=The money spent on wild animal protection should have been used to improve human lives. (過去分詞做定語)
Spring came on, and the trees turned green. (并列句)
= when spring came on, the trees turned green.( 時間狀語從句)
=Spring coming on, the trees turned green. (獨立主格結構)
Topics of punishment of criminals always arouse people’s attention. (簡單句)
=Topics of the punishment of criminals never fail to arouse people’s attention.
(雙重否表肯定)
= Never do topics of the punishment of criminals fail to arouse people’s attention. (倒裝句)
通過這些例句，學生應該可以看到從簡單句到復合句式的轉換，句式的多樣性，是保證一篇作文取得高分的硬性要求，也是一個學生語言高水平的體現。
