AEIS考试旨在考察学生的英文和数学能力。数学对绝大多数中国学生而言不是问题，因为大部分学生会因为英语的原因降级报考。英语语法里面很重要的一部分，是句子的构成。今天课窝网分享关于英语中部分倒装用法：

　　把be/助动词/情态动词提前到主语的前面

　　Is am are was were(be动词)do does did(助动词) can could would may will might(情态动词) 等

　　1.only所修饰的副词、介词短语或状语从句放在句首时, 要进行部分倒装.

　　Only then did I realize the importance of learning English.

　　Only after he came back was I able to see him.

　　注：only修饰主语，仍用自然语序，如：Only socialism can save China.

　　I seldom go to the cinema.

　　倒装：Seldom do I go to the cinema.

　　我很少去看电影.

　　I have never seen such a performance.

　　倒装：Never have I seen such a performance.

　　我从来没有看过这样的表演.

　　2. 否定副词及介词短语的否定词位于句首时。

　　高考常考的这类词或词语有：never , not, seldom, hardly, little, nowhere, by no means, in no time等 。

　　3.not until 引导的从句位于句首引起的主句部分倒装

　　He didn’t finish his homework until his mother came back.

　　倒装：Not until his mother came back did he finish his homework.

　　直到他的妈妈回来，他才完成作业。

　　The mother didn’t leave the room until the child fell asleep.

　　倒装：Not until the child fell asleep did the mother leave the room.

　　等到孩子睡着了，妈妈才离开房间.

　　注意：当Not until引出主从复合句，主句倒装，从句不倒装。

　　4、as/ though (虽然，尽管)引导的让步状语从句

　　名词形容词副词分词+asthough+主语+其他

　　Although I am ugly, I am gentle.

　　倒装：Ugly as I am, I am gentle.

　　Though he is a child, he has to make a living.

　　倒装：Child as he is, he has to make a living.

　　注意：从句的表语是名词，其名词前不加任何冠词

　　5.用于so nor neither 开头的句子

　　A、So +be/助动词/情态动词+主语

　　某人也是如此

　　Nor/neither +be/助动词/情态动词+主语

　　某人也不是如此

　　1). 他喜欢读书，我也是.

　　He likes reading very much. So do I .

　　2). 我从来没有去过广州大学，他也是.

　　I have never been to Guangzhou University, neither/ nor has he.

　　Betty is a nice girl. So she is

　　B、So +主语+be/助动词/情态动词

　　某人确实如此

　　6.在 hardly/scarcely/…when; no sooner…than; not only … but also;so...that; such…that 的倒装句中，前倒后不倒.

　　hardly/scarcely/ no sooner后句子的谓语用had done, when/than后句子的谓语用一般过去时

　　(1) Hardly / Scarcely had he fallen asleep when a loud knock at the door awaked him.

　　(2) No sooner had I reached the station than train moved.

　　(3) Not only is he interested in football but also he plays it well.

　　(4) So hard does he work that he has made great progress in English.
