5．A。with所引导的结构在句子中作伴随状语。“with+n.+doing/done/介词短语”为固定结构。noise与go on之间为逻辑上的主动关系，故选A。

4．B。make oneself at home“别拘束”；help oneself to“自行取用(食物等)”。

3．D。the biggest ocean与compare存在逻辑上的被动关系，所以须用过去分词短语作状语，其前的when用来突出时间的意味。

2．C。句意：除了知道她是北京人之外，我对这位年轻女士一无所知。依据题意，此处应排除besides; except后可接that引导的宾语从句，但that不能省略；except for和except that同义，但前者后面不能接句子。

1．A。这是一个定语从句。先行词为situation“境地”，所以要用where来引导。
