The snowstorms created gigantic passenger backups.
暴风雪造成大量旅客滞留
----------------------------------------------------------------------
名词backup,一个常用的意思是“后备,备份”(A copy of a program or file that is stored separately from the original; A reserve or substitute);另一个常用的意思就是这个句子里的“阻塞、滞留”(An overflow or accumulation caused by clogging or by a stoppage)。表达“滞留”还可以用另外一个动词,strand。
例句:
For the stranded passengers, there are few alternatives.
对滞留的旅客来说,没什么选择的余地。
海纳百川,有容乃大;壁立千仞,无欲则刚。
