对于多数雅思考生而言作文高分的取得并非易事，关键之一在于考生想要写得一手好文章，就必须注意语法在写作中的应用了。想要雅思作文写得好，语法知识不可少!下面，就和前程百利小编一同来学习一下吧。
独立主格：
1. 名词/主格代词+现在分词
名词/主格代词与现在分词之间主谓关系(主动)。
如：
The girl staring at him (= As the girl stared at him), he didn't know what to say.
姑娘两眼望着他，他不知道说什么好。
Time permitting (= If time permits), we will go for an outing tomorrow.
如果时间允许的话，我们明天去郊游。

由于约翰不在，哈里就得做这个工作。
Miss Yang being our English teacher, we'll have a happy time this term.
杨小姐当我们的英语老师，本学期我们将会很愉快。
He sat in front of them, dressed in a plain, ill-fitting suit, never moving, his dusty face masking his age.
他一动不动地坐在他们面前，穿着一套普通的、不合身的西服，他满面灰尘，让人看不出他的年龄。
2. 名词/主格代词+过去分词
名词/主格代词与过去分词之间的动宾关系(被动)。
如：
The problems solved (= As the problems were solved), the quality has been improved.
随着问题的解决，质量已经提高了。
Her glasses broken (= Because her glasses were broken), she couldn't see the words on the blackboard.
由于眼镜摔坏了，她看不见黑板上的字。
She gazed, her hands clasped to her breast.
她凝视着，双手叉在胸前。
3. 名词/主格代词+不定式
名词/主格代词与不定式之间是主谓关系，可表将来，强调一次具体性的动作。
如：
He is going to make a model plane, some old parts to help.
借助于一些旧零件，他要做一个飞机模型。
They said good-bye to each other, one to go home, the other to go to the bookstore.
他们道别后，一个回了家，一个去了书店。
Here are the first two volumes, the third one to come out next month.这是头两卷，第三卷下个月出版。
So many people to help him, he is sure to succeed.
有如此多的人来帮助他，他一定会成功的。
A number of of ficials followed the emperor, some to hold his robe, others to adjust his girdle, and so on.
许多官员尾随皇帝之后，有的拎着皇帝的衣袍，有的则给他整腰带等。
4. 名词/主格代词+形容词或形容词短语
形容词或形容词短语说明前面名词或代词的性质或状态)。
如：
An air accident happened to the plane, nobody alive.
那架飞机遭遇了空难，无一人生还。
So many people absent, the meeting had to be called off.
这么多人缺席，会议不得不取消。
She appeared in front of us, her face bright with joy.
她出现在我们面前，脸上闪耀着快活的神色。
He sat in the front row, his mouth half open.
他坐在前排，嘴半开着。
The floor wet and slippery, we stayed outside.
由于地板又湿又滑，我们呆在屋外。
5. 名词/主格代词+副词
副词也多是说明前面名词或代词的状态。
如：
He put on his sweater wrong side out.
他把毛衣穿反了。
The meeting over, they all went home.
会议一结束，他们就都回家了。
状语前置：
状语前置就是把一个修饰动词的状语结构，如介词短语，分词形式或动词不定式引导的短语放到句首、雅思写作中状语前置是很拿分的句式，不过很多考生都没意识到这一点。请看下面从剑桥提供的范文中节选的句子：
1. Like self-awareness，this is also very difficult to achieve，but I thinkthese are the two factors that may be the most important for achieving happiness.
2. Throughout the century，the largest quantity of water was used for agricultural purposes.
3. With a population of 176 million，the figures for Brazil indicate how high agricultural water consumption can be in some countries.
使用状语前置的最大优点是让单调的句子有了跳跃的节奏感、考官一天看上百张考卷，看到这样的句子也会心情愉悦。
插入语：
此种语法结构是可以理解为是状语前置的另一种变体，它将状语结构提到了主句的主语和谓语之间、插入语也是相对地道的英语表达方法、请看以下几例：
1. Universities，when it is functioning well，should offer both theoretical knowledge as well as professional training.
2. So overall，I believe that，attending school from a young age is good for most children.
插入语的功能和状语前置基本相似，都能使句子更有跳跃感和地道。
倒装句：
这种语法现象相信很多学员都学过，即把谓语提前到主语之前，用在作文中比较新颖。
我们先来看以下几个例子：
1. The parents should spend time on their children，they should also communicate with them.
2. We can never lose sight of the significance of education.
以上两句话都没有任何错误，但是读来非常平淡，没有任何特色，如果我们用倒装句，出来的效果就完全不一样了。
1. Not only should parents spend time on their children，they are also advised to interact with them.
2. On no account / by no means / in no way can we lose sight of the significance of education.
以上就是想要雅思作文写得好,语法知识不可少的详细内容，考生要多多参考学习，不过只记在本子上或是脑海里却不知道应用，那么又怎么会有所成效呢，考生要学以致用才行。希望考生能够考出满意的雅思成绩，更多雅思备考经验我们将会陆续为大家更新，欢迎咨询我们的热线电话400-890-6000。
