in occupation of/in the occupation of

in occupation 与 in the occupation of 虽然只差一个定冠词 the,但意义和用法却是完全不同的。例如：

1. No one is yet in occupation of the house. (in occupation of = occupying) (Wood) 现在还没有人住那所房子。

2. That farm has been in the occupation of the same family for over a hundred years. (in the occupation of = occupied by) (Wood) 那个农场归同一个家庭所有已经一百多年了。
