Question

My brother fell while he was riding his bicycle and hurt himself这句话有问题吗

根据这个句子的形式不应该是 主句（过去式）+when/while+从句（过去进行时）吗，那为什么句中为hurt，不应该是hurting吗

Answer 1

这个句子的主干是这样的： My brother fell and hurt himself. and前后都是过去时， fell和 hurt是并列谓语。 而从句while he was riding his bicycle是前面my brother fell的时间状语从句。

Answer 2

这个句子其实是 My brother fell and hurt himself while he was riding his bicycle

Answer 3

错
