never to be found ,动词不定时与动名词的区别?

此处的不定式 never to be found again 是结果状语,等于从句 so that it could never be found again 或者 so as never to be found again,意思是“以至于永远也别指望再找到”.
不定式和分词（不是动名词）都可以作状语,但是它们的分工不同.不定式充当的是目的或结果状语,而分词充当的是时间、原因、条件、伴随方式状语,跟在句后的分词短语往往是伴随状语.如果此处改为 it never being found again,意思变成了“与此同时手机永远也没人看得到”
