全部倒装（地点状语 + 谓语动词 + 主语）
形式：主语、谓语动词、地点；条件：前提是动词为系动词/不及物动词（在/来/去），且有地点
功能：将主语和地点倒装，实现句式平衡、由远及近
Most of Debbie's school friends will be waiting for her on the English coast. Among them will be
Debbie's mother, who swam the Channel herself when she was a girl.
此处地点前置，否则Most of Debbie's紧跟着就是定从，这样系动词和表语部分远远短于非限定性定从，导致头重脚轻、句式不平衡部分倒装（助动词 + 主语 + 动词）
助动词位于主语之前，就是部分倒装。部分倒装的主用就是用于强调句
It is only in recent years that it has gained an evil reputation. #强调句：it is/was 要强调的内容...that，下划线部分是强调内容
It has gained an evil reputation only in recent years.
Only in recent years has it gained an evil reputation … #部分倒装条件 1：only 状语位于句首
条件 2：not only … but also …(as well)
- I not only spoke English very carefully, but very clearly as well
- Not only did I speak English very carefully,
