有关only的倒装用法有如下几项注意事项：
only若位于句首修饰状语，则倒装 ，如Only in this way can you learn english well；在句首的only若后一词为副词、介词短语或从句等状语，则主句用倒装结构，如Only in this way can you learn English well；在句首的only若后一词为主语，则不倒装，如Only five men were hurt in the accident；only和所修饰的状语如果不在句首，则不倒装，如The boy was helped out only when his father arrived in time.
