1.He often drops in my place on his way back.
2.The assistants are supposed to serve for the customers warmly.
3.There seems to have some spelling mistakes here,doesn't there?

1.He often drops in my place on his way back.
1.去掉my place,因为drop in就是拜访的意思..=go to visit me

2.The assistants are supposed to serve for the customers warmly.
2.去掉for,因为serve可以直接加名词.表示"为...提供服务"

3.There seems to have some spelling mistakes here,doesn't there?
3.doesn't 改成isn't.
