Please provide a better answer and explain in mandarin.
What is the differences among these sentences as below?
1)Which department does he work
2)Which department does he work now?
3)Which is the department he working for?
4)Which is the department he works for?
答
3是对的
1错在缺少介词,应该是work for
2和1一样,应该加介词in 或者 for
3是对的
4一句简单句中不可能既出现be动词,又出现谓语动词
