only then和only when的用法only then和only when,如何搭配had sb v-ed或者did sb v-ed举个例子only then_he realize the importance of learning English此处用did还是had?如果改成when呢?
用did,
如果改成only when ,
Only when he realized the importance of learning English
did he decide to study hard.
而且二者意义不同
only when 意思是直到...时候才.
only then 意思是知道那是
希望能给楼主些许帮助

Only when +时间+部分倒装(did sb done)
only then 直到那时用had sb v-ed
