翻译成英文：“因为A 公司的小红休假一段时间,所以请将邮件发给暂时接替她工作的小白”

楼上的,你们要写的是vacation 吧,你们写成了vocation.Vacation的主要意思是holiday,所以应该用on leave 比较贴切
Because Xiaohong from company A is on leave for a period of time,therefore please send the emails to Xiaobai who is temporarily taken over Xiaohong's work.
例句 Mr.Li is on leave for 3 weeks.

Because Hong is off on vocation, please sent your emails to Bai.

Please send the email to Xiaobai who replace xiaohong, as Xiaohong who is from A company is on vocation for a period.
