It was in the lab ______was taken charge of by Professor Zhang _____ they did the experinent.

Answer 1

解答如下：
前面用WHICH 或THAT 因为这是一个定语从句的结果 THAT WHICH 叫关系代词 它指代前面的LAB 充当了 后面was taken charge of by Professor Zhang 的主语 。

后面那个用THAT 在这个整个句子的结构 来说 是一个 强调句 强调句一般结构是it be +that

这句翻译如下：这个由张教授管理的实验室是给他们做实验用的

Answer 2

强调的是 in the lab which was taken charge of by Professor Zhang
