  倒装:全部倒装和部分倒装

  谓语部分所有单词都放在主语前是全部倒装。谓语的一部分放在主语的.前面是部分倒装。

  谓语中的一部分通常是指:1、系动词;2、助动词;3、情态动词。

  全部倒装的五条原则:

  1. There be句型;

  2. 以There或now开头的句子,且句子谓语动词为come或go;

  3. 以Here开头的句子,且句子谓语动词为系动词be; Here you are. 拿去。

  4. 以副词out, in, up, down, away开头的句子;

  5. 以状语开头的句子。

  倒装:六条原则

  1. so放在句首时表示承前肯定,这个句子用部分倒装;

  nor, neither放在句首时表示承前否定,句子也用部分倒装;

  2. 省略了引导词if 的虚拟条件从句,可以把从句中的had, should, could, were中的任何一个提到从句最前面的位置,构成部分倒装;

  3. as, though表示 尽管 时引导从句,从句中的表语可以置于引导词之前构成部分倒装;

  系动词后面的部分就是表语,形容词、名词、名词性短语可以置于系动词之后。

  关于英语语法

  强调句结构

  常用的强调句结构是it 引导的句子,结构为It is(was)+ 被强调部分+ that (who) + 句子的其余部分。此结构强调的成分限于主语,宾语和状语。例如:

  It is from the sun that we get light and heat. 我们是从太阳那儿获取光和热。

  It was not until I had read your letter that I understood the true state of affairs. 知道读了你的信,我才知道实际情形。

  典型例题

  1)It was last night ___ I see the comet.

  A. the time B. when C. that D. which

  答案C. 强调句的结构是: It +be +强调部分 + that (who))+ 主谓句。 强调句的连词只有两个,that和who。当强调的部分是人,且为句子的主语时,才用 who,其余用that。再如:原句:My father did the experiment in the lab yesterday evening.

  强调主语: It was my father who did the experiment in the lab yesterday evening.

  强调宾语: It was the experiment that my father did in the lab yesterday evening.

  强调时间: It was yesterday evening that my father did the experiment in the lab. (注意不用when)

  强调地点: It was in the lab that my father did the experiment yesterday evening.

  2)It is ten years ___ Miss Green returned to Canada.
