Answer 1

D

试题分析：考查定语从句和强调句型的融合。强调句型：it is/was被强调成分that/who其它成分；其最大的特点是去掉it is/was…that/who…句子仍然成立。本句强调的部分是in the lab which was taken charge by Professor Wang.故第二空使用that，第一空which was taken charge by Professor Wang修饰先行词the lab。定语从句中缺少主语，故使用关系代词which，避免与第二空的that重复。句意：就是在王教授负责的那个实验室里，他们做了这个实验。
点评：强调句型：it is/was被强调成分that/who其它成分；其最大的特点是去掉it is/was…that/who…句子仍然成立。经常会在强调句型的被强调成分中加入定语从句。
