Question

He was all but killed by the traffic accident , which I think happened by no accident 。

谁能帮我划分一下句子成分。 多谢。

Answer 1

He（主语） was all but killed by the traffic accident （谓语）, which I think happened by no accident （非限制性定语从句）。
非限制性定语从句成分：
which（关系代词作宾语从句中的主语） I （主语）think（谓语） happened by no accident 。
