Was it on a lonely island ______ he was saved one month after the boat went down？(2011·四川卷15)
A. where B. that C. which D. what
【解析】选B。该句为含强调句型的一般问句。强调了地点状语on a lonely island，不能选where。它不是定语从句。该句可以还原为一个陈述句：He was saved one month after the boat went down on a lonely island.
考点1.强调句型的基本结构
Is ______ three hours ______ the boy ______ family is poor to come to school on foot?
A. it; that; whose B. it; that it takes; whose
C. it for; that it takes; whose D. it; when; that
