二、face、encounter、confront 指面对、面临、遭受，用法：
to face/encounter/confront problems (difficulty issues changes dangers disasters consequences ……)
例句：

三、suffer (from)“遭受”用于一个具体的不利内、外因素、问题或结果：
to suffer (from) weakness (problems issues attacks failures overflow congestion threats insecurity……)
例句：Their plan suffers from inadequate funding.（他们的计划遭受资金不足。）

注意不能说suffer from challenges。
四、expose指遭受外部引发的问题或外部不利因素，它有两种用法：
to expose sth. to attacks (problems issues disorder disaster obstacles threat……)
或：be exposed to attacks (problems issues disorder disaster obstacles threat……)

因为weakness 不是外部因素，所以不能说be exposed to weaknesses。
注意也不能说be exposed to challenges。
五、还有be subject to，它的意思和上面稍有不同，它表示某事物的脆弱性：易于遭受问题或不利外部因素的影响，例如：
