Back in high school in college, I worked for my college building company.

我曾经为我的大学建筑公司工作过。

The building company yesterday announced completion of the second passage of the Changjiang Tunnel.

昨天建设公司宣布长江隧道的第二条通道完成。

It's better and more profitable, in my opinion, to have a pool cleaning company than a pool building company.

在我看来，拥有一个游泳池清洁公司比游泳池建筑公司更好更有利可图。

Note: Raw space does not equip any exhibition frames and facilities, the exhibitors can arrange the special decorate work by oneself or entrust the building company recommended by the organizer.

注：空场地不带任何展架及设施，参展商可自行安排特殊装修工作或委托组织单位推荐的搭建公司。

The company rented the building, occupied part and sublet the rest.

公司租下整个建筑物，使用部分的空间然后把剩下的地方转租出去。
