"only"引导的倒装句是指 当"only"置于句首并修饰状语时，主句需要使用部分倒装的结构。具体来说，"only"后面可以跟副词、介词短语或从句等状语，当这些状语位于句首时，主句的谓语动词需要放在主语之前，形成倒装语序。这种倒装结构有助于强调状语所表达的时间、地点、方式或条件，使句子更加生动和强调。

在使用"only"引导的倒装句时，需要注意以下几点：
"only"必须放在句首，并且后面通常跟的是副词、介词短语或从句等状语。
主句需要使用部分倒装，即将谓语动词放在主语之前。
如果"only"后面直接跟的是主语，则不需要使用倒装结构。
通过掌握这些规则，可以更准确地运用"only"引导的倒装句来丰富句子的表达和强调效果。
