国会大厦是世界最大的哥德式建筑物之一,占地三万平方公尺.矗立於泰唔士河畔,气势雄伟,外貌典雅.国会大厦内有一千间房间,自13世纪以来此处便是英国国会开会之处,也同时兼为国王宫殿.但於1512年发生大火後,英皇爱德华六世在1547年把它拨给下议院,从此成为国会大厦.这里的西敏寺大厅(WestminsterHall)建於1097年,是唯一剩下来的旧建筑部分,分上议院(HouseofLords)和下议院(HouseofCommons).西敏大厅侧有一座闻名中外的「大笨钟」(BigBen)大笨钟每小时报时一次,钟声响起时远近可闻,且是十分准时,英国BCC电视台也是依据此钟报时.

　　您好：standin站立于：；坐落于，位于：standon位于，坐落于：；基于，取决于，以…为根据；依靠：单从解释上来说，两个词都可以，但我们在后接某个地点时就会用in比较多了。望采纳！
