in front与in the front区别

in front和in the front都需要加of再加可数名词复数,表示在……的前面,但二者又有区别：
in front of 表示广义的在……之前,没有空间范围的限制,反义词是behind.例如:
1.Tom sits in front of me.汤姆坐在我的前面.
2.There is a beautiful garden in front of my house.我家前面有一个美丽的花园.
in the front of表示在一定空间范围内的前面,反义短语是in the back of.
例如：
The blackboard is in the front of our classroom.黑板在教室的前面.
The national flag is in the front of the playground.国旗在操场的前面.

in front of the classroom 在教室（外部）前面
in the front of the classroom 在教室（内部）前面

in front--在什么前面，无范围限制
in the front——在什么前面，无限制
e.g:The tree is in front of us.
The blackground is in the front of the classroom.

in front表示在外面
in the front表示在里面
比如说在教室前面有个讲台.这是在教室里面,用in the front of
在教室前面有棵树,这是在教室外面,用in front of
