I lost a book,____I can't remember now.

问题描述:

I lost a book,____I can't remember now.
A whose title       B.its title         C the title of it        D the title of that

选A意思是:我丢了本书,书名我现在记不起来了.这是一个非限制性定语从句,从句部分还原是:I can't remember its(用whose代替) title now.B和C错误,是因为不符合定语从句的句式,假如用BC,那就成了并列句,但原句用逗号...
