在雅思写作中，考生如果想得到，除了需要依靠较出彩的思想、单词以及常见关联词外，还需要运用句型。在这些句型中，除了常见的从句（定语从句、状语从句以及名词性从句）之外，强调形式和倒装形式更是拿分的关键点。以下，朗阁雅思培训中心的老师将对此类句型进行总结。
一、强调形式
强调形式总共分成五大类：
1. 对动词进行强调（dodoesdid + V）
Sitting in front of the screen does damage the eye and physical posture of children.
Some people do believe that the overuse of chemicals (e.g. Fertilizers and pesticides) do pose a threat to the well-being of local people.
2. 双重否定可表强调
We cannot deny that receiving the distance education is never without drawbacks.
It is not unrealistic for the government to reduce the amount of waste.
3. 比较状语可表强调
Nothing is more important than to develop the children’s ability of learning on their own.
Students would have greater capability to deal with their academic life than those who do not have the gap year spent in working or travelling.
Nothing is more imperative than to learn from the past.
4. what引导的主从可表强调
What is related to the economic collapse is the failure of the government’s policies.
What really matters is cooperation.
5. 强调句型可表强调
It is/was + 被强调的成分 + that/who, 所强调的可以是单词、短语，也可以是从句，但必须其结构完整。被强调的成分可以是主语、表语、宾语、同位语、状语等，但不能是定语或谓语。
It is the government that should shoulder the responsibility to protect the endangered species.（对主语强调）
It is teachers who are competent to instruct their students to be a good social member.（对主语强调）
It is through job training that the young unemployed would have the opportunity to get jobs again.（对状语强调）
It is the large company which the public think polluting the water supply.（对宾语进行强调）
注：强调句中的时态要根据原句的时态而定。即原句为过去某种时态，则强调句中的be就用过去时；原句为现在的某种时态，强调句中就用be的现在时态。有时还可以用It might be/must have been/can’t be…that等句式。
例句：
It is because people are stuck in the traffic that they spend longer time in travelling.
It might be the lack of guidance of parents that leads to the going astray of young people.
强调句的判断：强调句型可以通过“还原法”来进行判断，若删除强调句型结构后，句子能还原为一个完整的句子，就是强调句。强调句可以看作是用固定的表达-It is/was…that (which, who, whom, where, when)…, 将句子的某个成分（除了谓语）进行重点强调。但是，去掉这个固定的句型部分，句子本身并无任何变化。
二、倒装形式
倒装共分两类：全部倒装和部分倒装。全部倒装是指将全部谓语动词都放在主语之前。部分倒装是指将谓语的一部分如助动词，系动词或情态动词放在主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did, 并将其放在主语之前。
A. 全部倒装：把全部谓语放在主语前。
1. there be句型（特殊的全部倒装句型）
There be…是一种较为常见的句子结构，通常用于表达“某地有某人或某物”，在使用此句型结构时，应注意下列问题：
1) 主谓一致
例句：
There is little opportunity for children to stay at home until the age of 7 because their parents are both working.
There are many reasons why we should not slaughter animals for their fur or leather.
2) be动词可以是任何时间状态
例句：
There have been many government which invest a large sum of money in researching the space.
There has been a discussion over whether children should be sent to school at a young age.
3) 在There be结构中除了运用动词be之外，还可以用seem, appear, happen, exist等。在这种句型中，谓语的单复数形式根据靠近谓语的主语而定。
例句：
There seemed to be no permanent solution to the disappearance of minority languages and cultures.
2. there here now then放在句首时，句子进行全部倒装。
Now is the time to realize the seriousness of this problem and take actions immediately.
3. 方位状语开头时，句子进行全部倒装。
On the internet are provided all kinds of entertainment activities.
In books are embalmed the greatest thoughts of all ages.
4. 主语与表语互换位置（当主语过长而表语过短时，可以把主语与表语互换位置从而构成全部倒装）
Well-known is that energy crisis poses a threat to the society.
Important is that the government raises people’s awareness of the environmental protection.
5. 伴随状语开头（With或Along with放在句首时，句子应该全部倒装<
