notonly开头的倒装句

Not only开头的倒装句
Not only位于句首用部分倒装。

部分倒装就是把系动词，助动词或者情态动词提到主语前面，如果句子中还有其它的动词，那么这些动词依然放在主语后面。

例如：Not only do MP3s provide us with fun, but also they can help us learn English. MP3不仅给我们提供乐趣，而且能够帮助我们学英语。

only位于句首修饰状语要倒装。

在句首的only,如果后面跟了副词、介词短语或从句等状语，则主句用倒装结构。

例如：Only in a big city was it possible to buy a new wheelchair.只有在大城市里才能买到新轮椅。

not only加倒装，but also不倒装。

not only...but also倒装主要用法:就是谓语动词要遵循“就近一致原则”例如: Not only the students but also the teacher was invited.不仅学生们被邀请，而且那位教师也被邀请了。

not only. . . but also倒装句的用法:
连接二个分句(并列句)，即Not only和but后面都有主谓结构时，如果not only位于第一分句主语之前，则该分句要部分倒装;后一个分句，即but后面不用倒装。

如果not only不是位于第一分句主语之前，前后两个分句的主语相同，可以改为并列二个谓语，此时则不倒装。

例如:Not only had the poor man been arrested, but he had been sent to prison as well. =The poor man had not only been arrested but sent to prison as well.这个可怜的人不仅被捕了，还被送进了监狱.
如果Not only... but...连接两个主语，不能使用倒装。

例如: Not only the teachers but also the students love their school very much. 不仅老师们，学生们也非常爱他们的学校。
