解释下这句话,并分析一下语法
no one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted.

Answer 1

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted.
众所周知,水资源短缺是全世界面临的严峻问题.
No one can have failed to notice the fact.
是主句.
that water shortage is a grave problem
是 fact 的同位语从句,用来解释 fact,其中 that 是它的引导词.
with which the whole world is confronted
是 problem 的定语从句.其中 which 是关系代词,用来指代 problem.因为 problems 作的是 confront 的宾语,所以 which 前要加介词 with .
