专业翻译公司发现在英语语法中，倒装结构通常是不太容易完全理清的一部分，在准备四级考试的时候也应当适当地准备一下。在英语表达中，当句子的正常语序表述出来是错误的内容时，我们就需要进行主谓语的位置变换，也就是通常说的倒装，在写作文中，为了凸显考生的英语水平比较好，有些考生也会选择用部分倒装，为了方便大家积累语法知识，老师为大家详细讲解了有关倒装句的内容，希望考生能够认真看一看，用这些倒装句的知识点写出自己的优秀作文。

三、部分倒装

部分倒装指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化。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，并将其置于主语之前。

1. 下列否定词及含有否定意义的词组修饰状语时，若置句首，句子的主谓要部分倒装 ：never, no, neither, not only, hardly, scarcely, little, seldom, rarely, not until, nowhere, at no time, on no account, in no respect, in no sense, by no means, in no way, no longer, no less, no more, no sooner than, under no circumstances, in vain, still less。

例如：Not only is its direct attack on their discipline, it bypasses the essence of what sociologists focus on. Under no circumstances should we do anything that will benefit ourselves but harm the interests of the state.

2. 以only修饰状语开头的句子，句子的主谓要部分倒装

例如：Only when you have obtained sufficient data can you come to a sound conclusion.

3. 以下列副词或短语开头的句子，句子的主谓要部分倒装 ：often, so, well, to such a degree, to such an extent, to such extremes, to such a point，many a time。

例如：So involved with their computers do the children become that leaders at summer computer camps often have to force them to break for sports and games.

四、特殊从句的倒装

1. 让步从句的倒装

(1) as引导让步状语从句，必须采用倒装结构，但不是主谓倒装，而是将被强调的内容置于句首。例如：Much as I have traveled, I have never seen anyone to equal her, in thoroughness, whatever the job.

(2) 出现在句型be+主语+其他中。例如：Our civilization has accumulated an incredible amount of knowledge—be it scientific or artistic. The business of each day, be it selling goods or shipping them, went quite smoothly. Come what may, I’ll be on your side.

2. 比较从句的倒装

as, than引导的比较从句中，如果主语是名词短语且较长，经常采用倒装结构(不倒装也可以)。注意：这种结构主语一般为名词，如果是代词则不倒装。

例如：Hydrogen burns much more cleanly than do other fuels and is easy to produce. Reading is to the mind as is exercise to the body.

在以上倒装结构的语法知识点中，考查较多的还是部分倒装，考生也应该重点关注部分倒装的情形，熟练掌握这些知识后，在写作中考生一定可以轻松应对了，预祝各位考生都能取得满意的成绩!
