A.that B.there C.which D.where
这个题正确答案是D 是北京市海淀区2008年高三年级第二学期期中练习第34题,到底是定语从句还是强调句呢?如果是定语从句,那么选择that后,去掉it was……that句子也完整啊,为什么不选择A?

答案

这里不是强调句啊,是定语从句.
去掉it was……that后句子是at the workshop we did research together two years ago.这个句子并不完整.少了定语从句的先行词where.应该是at the workshop where （in which）we did research together two years ago.所以这里是定语从句,where是先行词.
如果改完整的话句子应该是：
It was at the workshop (where we did research together two years ago that) that i get to know the professor.这才是带定语从句的强调句.
