题目

一道有关定语从句的题He asked me _____.
He asked me _____.
A.whick book was his.
B.which book his book was
为什么A对，而不是B对,
比如:This is the pen (which) he bought yesterday.
这个句子的定语从句就不同于我问的那个.

答案

He asked me后面带的是从句,从句都要求用陈述语序.
which book was his 就是陈述语序,谓语在主语后,在这里which book是主语,was是谓语.
而B选项句子根本不通,应该表达为which book was his book.这才是陈述语序.
