(1)in front of表示“在……的前面”(有一定距离的前面,也可以理解在物体范围外的前面),其反义词是behind,表示“在的后面”。例如:There is a river in front of the house.There is a house behind the river.
(2)二者的区别:in the front of与in front of具有不同的含义。前者表示在某一范围之内的前部,后者表示在某一范围之外的前面。例如:There is a big desk in the front of the classroom.在教室的前部有一张大桌子。There is a tree in front of the classroom.在教室的前面有一棵树。
