situate 和 locate 还有site的区别

Let me give a try:
situate 一般指在...情况,不太用於实质,如房子,学校,公园等.
Because of the bad economy, they are situated in uncertainty.(因为经济不景气他们处於未知的情况下)

locate 一般用於实质的.
I located a place where we can have party on Saturday.(我找到一个地方可以在星期六开party用)
The school locates next to the zoo.(这个学校座落於动物园旁边)

site多用於场地,例如:盖房子的工地,比赛的场地.
The car accident site was closed for investigation.(为了调查,车祸现场被封锁)

太广泛了 ，从何说起 ？
