he suggestion that we set off now has been accepted是什么意思

题目

he suggestion that we set off now has been accepted是什么意思
这是个同位语从句,他建议我们现在出发?为什么后面要有accepted?

答案

He是人称代词,接suggestion名词怎么都别扭啊,应该是his吧?
His suggestion 是先行词,that后面跟的we set off now是同位语,解释suggestion的内容.
而这个句子的主句是His suggestion has been accepted.他的建议被接纳了.
而这个建议就是we set off now.
所以整个句子的意思是：His suggestion（ that we set off now）has been accepted.他的建议——“我们现在出发”被接纳了.
