1. Then we will open the floor for discussion(Page 22, line8) 之后我们将展开集体讨论。
句中the floor意思是“（在会上的）发言权”。常用的短语有：get/have/be given the floor 取得发言权，hold the floor长篇大论地发言。如：
Dale was delighted to know that he had managed to gain the floor in the next conference.
戴尔很高兴地得知他已获准在下一次会议上发言。
另外，floor还有“楼层”的意思。如：
To my surprise, the girl who lives two floors above is my desk mate in the primary school.让我惊奇的是，那个住的比我高两层的女孩是我小学时的同桌。
