They were initially mistaken for students late to class who were sneaking in over the back wall.

最开始他们被误认为是因迟到而偷偷翻墙进入学校的学生。

I arrived late to class because the train came late.

我上课迟到了，因为火车晚点了。

Tell Mr. Givens I may be a little late to class.

跟吉文斯老师说我可能会晚点进教室。

So, if you're a little bit late to class, it's probably a bit too much to say " I sincerely apologise for being late."

所以，如果你上课迟到了的话，说“我真诚地为迟到感到抱歉”有点太过了。
