The snowstorms created gigantic passenger backups.
注释
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。 |
