after( what )seemed to be a long time ,the old man went out of the professor's sitting room
A it B that C which D what 所选答案是非限,但如何分析句子成份啊?
after( what )seemed to be a long time 介词短语作定语 after是介词 what从句是宾从
the old man 是主句主语
went out of 是主句谓语
the professor's sitting room是主句宾语
之所以选择what,是因为after后面的宾从中缺少主语,能承担这一任务的只有what
供参考.
