倒装句是英语中一个非常重要的语法点，正确运用倒装可以给文章添色加彩。下面通过两道高考题了解一下only引导的倒装句。
例1：Only with the greatest of luck ____ to escape from the rising flood waters.(2012上海)
A. managed she
B. she managed
C. did she manage
D. she did manage
[解析]
本题选C。“only+方式状语”位于句首时，句子要用部分倒装，即将助动词放到主语之前。A为完全倒装，故排除。句意为：仅仅是因为运气好，她才得以从不断上涨的洪水中逃生。
例2：Only after Mary read her composition the second time ____ the spelling mistake.(2012天津)
A. did she notice
B. she noticed
C. does she notice
D. she has noticed
[解析]
本题选A。“only+时间状语从句”位于句首时，主句要用部分倒装，而且可根据read判定本题时态是一般过去时，故选A。句意为：玛丽是在把作文读了第二遍之后才注意到那个拼写错误的。
[提示]
1.only修饰主语时，句子不用倒装。
例：Only our parents will always support us.只有我们的父母会一直支持我们。
2.only修饰状语从句时，从句不用倒装，主句用部分倒装。
