我们都尊敬系里经验丰富的老教师。

[误] We all respect the experienced aged teachers in our department.

[正] We all respect the experienced old（或 senior）teachers in our department.

注：aged 往往有“年迈力衰”的含意，用作原句的译文不恰当。我们可以说：We should take care of the sick
and the aged.我们应当照顾病人和老人。I go home to see my aged parents at weekend. 周末我回家看望年迈的双亲。因为在两个例句中强调的是“年老体弱”。
