Great changes have taken place since then in the factory _______we are working.

题目

Great changes have taken place since then in the factory _______we are working.
为什么是where where是in which 句子中不是we are working in the factory不缺成分吗

答案

确实是WHERE=IN WHICH,这里的IN是跟在后面的WORK后的,还原就是in the factory which we are working in.=in the factory where we are working.因为这里的Which单单替代了Factory所以需要IN这个副词的.
