・That must have been tough!

要用英語說「那一定很辛苦吧！」，
可以用「That must have been tough!」 來表達。

that是
「那個」
must have been是
「一定很～」
tough是
「艱苦的，困難的」的意思。

例句為下，
「I heard that a colleague was kept waiting at the airport for 5 hours due to engine trouble on the plane. That must have been tough!」
（中文翻譯：我聽說因為飛機引擎故障，同事在機場等了5個小時。那一定很辛苦吧！）

用英語可以這麼說。
