……,instead,………instead为什么不能用however如He didn't answer me,inste

最常见的词组是 instead of
instead作为副词用,在顺接句子中译为“代替、替代、顶替”,在转折句子中译为“相反、然而”,在英语学习中,有些词要围绕它的意思灵活多变的进行释义.
例句：
1.Mr Crook wasn't come back,ask Mrs Crook instead.
Crook先生没回来,问问Crook太太吧（顺接关系）
2.Mr.Crook didn’t come back at the usual time.instead ,he met some friends and stayed out until midnight instead （为副词,是“相反”的意思,整句话的意思是,昨晚Crook先生没按时回家,相反,他遇见了一些老朋友,在外面呆到午夜.）
总结,例句中instead均为单独使用,但楼主可以试着将例句转换为“instead of”形式,是不是对此问题理解更深刻了?
如：He didn't answer me,instead,he asked me another question → He asked me another question instead of answering me.
