选择题
It is in this laboratory ______ is run by Mr. Wu ______ the experiments are done.
A.which; that
B.that; which
C.where; that
D.that; where
答案
A
题目分析:考查定语从句和强调句型.第一空which引导定语从句which is run by Mr. Wu修饰先行词this laboratory.第二空that与it is构成强调句型。句意:就是在吴先生管理的这个实验室里,这个实验被做的。故A正确。
点评:短语从句的重点在于分析句子成分。强调句型的重点在于找到被强调的成分。
