比较两个词的英语解释：实际上，真正弄懂一些词的区别，还是要认真研究它们的英文释义，这样对大家弄清它们的区别是很有帮助的。这就是为什么，学英语专业的学生，起初都要买一本Longman字典，它是英英字典，用2000左右的英语进行解释。

Locate：

1.discover the location of; determine the place of; find by searching or examining

Can you locate your cousins in the Midwest?

My search turned up nothing

2.determine or indicate the place, site, or limits of, as if by an instrument or by a survey

Our sense of sight enables us to locate objects in space

Locate the boundaries of the property

同：Situate

Situate：

1. determine or indicate the place, site, or limits of, as if by an instrument or by a survey

  Our sense of sight enables us to locate objects in space

   Locate the boundaries of the property

[同] locate

2. put (something somewhere) firmly

通过上面的比较，可以发现：

简单来讲，locate 和situate都可以表示“位于...”含义，但是，locate还可以表示“定位某物”或“找到某物” “查找”等。而situate不具备此含义。如：

The police are trying to locate the missing man.
警方正设法查明那个失踪者的下落。

The young man could not locate his lost pen.
年轻人找不到丢失的钢笔。
