按照中文可以譯成這幾種（比較不好）：
You're tired.
You’ve had a hard time
You’ve gone through a lot of hardships
建議可以分別用不同的方式來表達(dá)這個意思：
（1）對遠(yuǎn)道而來的人可以說：
Did you have a good trip?
You must have had a tiring journey
You must be tired from such a long trip
（2）對剛剛完成一項(xiàng)工作的人：
Well done.That Was a hard job．
Good work /Good job ,You’ve got a hard job．
或者直接說Good work /Good job
