They were cast adrift in a sea of events迷失在一大堆事件中.
请老师帮划分一下句子成分,主要问题是in a sea of events的修饰对象是什么?
They是主语,were cast谓语动词, drift作主补, in a seas of events是作什么成分修饰什么？修饰的是adrift还是were cast,还是were cast adrift？
管理员说，10.1后新改版上线，期望到时候可以充值鲜花，目前这个时刻都不能的。
《韦氏高阶》
cast adrift
[phrasal verb]
1
cast adrift:to cause to float on the water without being tied to anything or controlled by anyone—often used as cast adrift
a small lifeboatcast adriftin the open sea
2
cast adrift:to cause to float on the water in a boat that is not tied to anything or controlled by anyone—often used as cast adrift
Theywere cast adriftin a small, leaky boat.
—often used figuratively
Iwas cast adriftin a sea of confusion.
你的句子是第二义的比喻使用方法。既然cast adrift 被剖析为短语动词，in 介词短语就只能是状语了。
当然你也可以不按短语动词剖析。cast sb adrift in a sea of confusion. 形容词adrift被介词短语修饰构成形容词短语，作cast的宾补。
假如你了解cast adrift是短语动词，就把in介词短语剖析为状语。假如你不了解这个短语动词，你把adrift和in介词短语剖析为形容词短语作宾补（被动语态则为主补）。这二种剖析都是可以的。对理解句子意思没影响。
