The reason why I come here is very clear.reason是come here的宾语吗?为什么用why?

问题描述:

The reason why I come here is very clear.reason是come here的宾语吗?为什么用why?

why引导定语从句,修饰reason,这里的why=for which.
The reason for which i come here is very clear.
come here是个完整词组,不缺宾语.why在从句中做状语.
最后,这个句子可以分解为:
I come here for this reason.
This reaon is very clear.come here 为不及物动词词组吗?可以这样理解。come here是个动词+副词的短语,后面不需要宾语。及物动词或介词的后面才需要跟宾语。
