only + 副词 /介词短语/状语从句都可以表部分倒装，例子有哪些

希望在后面标明好

only+副词／介词短语／状语从句（句首状语由only修饰）
　　例句： Only recently did linguists
begin the serious study of languages that were very different from their own.
　　分析： 该句是复合句，that were very different from their
own是修饰languages的定语从句。
　　译文： 直到最近，语言学家才开始认真研究与他们自己所掌握的完全不同的语言。

　　例句： Only
when you have been absorbed in the study can you reach an idea whether it is
impossible or not to complete it on time.
　　分析： 该句是复合句，an idea与whether it is
impossible or not to complete it on time是同位语关系，only置于状语从句之前引起倒装。
　　译文：
只有当你全身心投入该研究中时，你才能得知能否按时完成。

　　例句： Only gradually was the byproduct of the
institution noted， and only more gradually still was this effect considered as a
directive factor in the conduct of the institution.
　　分析：
该句是由and连接的两个并列简单句，两个分句都是以only开头的倒装句，在前一分句中，主干部分是the by product of the
institution was noted， only gradually修饰noted；在后一分句中，主干是this effect was
considered...， 其中only more gradually修饰considered， as a directive factor作主语this
effect的补足语，介词短语in the conduct of the institution作directive factor的后置定语。
　　译文：
人们只是逐渐地认识到制度这一副产品，而在运行这种制度的过程中，认识到这种效果具有指导性作用的时间则更加缓慢。

Only then did I realize the importance of English. (副词) Only by this means can we learn English well. (介词短语) Only when the war was over was he able to get happily back to work. (从句)
