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)
Along with the population expansion comes the housing shortage in big cities.
With globalization have come many problems.
