很多船会停航在英语中可以说成："Many ships will be put out of service"。这个短语的来源是指许多船舶将被退役，不再进行航行。例如：

Due to the economic downturn, many ships will be put out of service and their crews will be laid off.
The shipping company decided to put several old ships out of service and replace them with newer, more efficient vessels.

在中文中，可以这样翻译这些例句：

由于经济衰退，许多船舶将被退役，船员也将被解雇。
这家航运公司决定退役几艘老船，并用更新、更高效的船只替换它们。
