1．lose oneself in…迷失在…，迷路于…，全神贯注于…之中

find强调在经过(寻找)（look for）后“找的结果”（找到或找不到）。如： I can't find my key.我找不到我的钥匙。

He found a business card in the drawer 他在抽屉找到一张名片 。 find也指（偶然发现）或（认为），是 如：

楚、弄明白的意思，后面如果接what /where/ why/ how等句子，多半用find out 带出。还有，find一定要加宾语（即发现的对象），find out则不必，如：

face to face 为副词短语，在句中做状语，修饰动词。如：

区别：face-to-face 为形容词，一般修饰名词做其定语。如：
