Are you aware of the difficulties that lie ahead of you翻成中文,that是什么从句,lie作什么成份,能否分析一下句子成份

翻译成中文就是：你意识到你面前存在的困难了吗？
that在这里是作关系代词，引导的是定语从句，在从句中作主语。先行词是difficulies，整个定语从句修饰difficulies。lie在从句中做谓语动词。

that是定语从句 修饰difficulties
difficulties that lie ahead of you 意思是在你前方的困难
Are you aware of the difficulties that lie ahead of you
你意识到你前方的困难了吗？

你意识到摆在你面前的困难了吗?
that lie ahead of you是定语从句 修饰宾语difficulties
You主语 aware of谓语 difficulties宾语 that后面定语从句
