7.Great changes have taken place since then in the factory _______we are working.
A. where B. that C. which D. there 选什么答案
in the factory where we are working。 这句话没问题吗 ? 前面已经有个借此in了,还可以用where这个状语吗? 那你看这句话有问题吗?we are working in in the factory 中间2个IN可以用?
不是说了前面还有一个in 嘛 , 有in了为什么还要加in which啊 ,应该加which才对啊
