Question

in the face of和be faced with有什么区别？

Answer 1

in the face of 有2种表达

(1) 人的脸上 it is pimples in the face of a boy (2)人的面子上 it is a ruin in the face of Tom

be faced with 意思是面对什么

Tom was faced of food scarcity.

Answer 2

这种现象属于：“及物动词 + 宾语” 结构，转换为“be + 过去分词（实为形容词） + 介词” 结构。前者重在动作，后者重在状态。例如：
face the difficulties = be faced with the difficulties

prepare his lessons = be prepared for his lessons

finish her homework = be finished with her homework

多说几句：
Be+动词过去分词的用法就是用于被动语态，再就是你可能看到的是过去分词形式作形容词的情况，比如the door is closed门是关着的。其他就没有了，下面是被动语态。请指教被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。一般现在时：am／is／are＋taught一般过去时：was／were＋taught一般将来时：will／shall be＋taught现在进行时：am／is／are being＋taught过去进行时：have／has been＋taught现在完成时：have／has been＋taught
