回答：1。Very few students can understand the professor's lecture as_____is very unfamiliar to them.
A.the subject of it  
B.the subject of which
C.the subject of whose
D.the subject of that
解析:本题选A
首先很明显排除CD,你应该明白吧?!
然后这里as引导从句，Very few students can understand the professor's lecture 为主句，这里as解释为＂因为＂
既然两句是主从关系，那么这里用it 代替lecture.
