This is the second time he's been sent home from school this month, so woe betide him if it happens again!这是他本月内第二次被从学校赶回了家,要是再发生一次这样的事,他就要倒霉了。Woe betide anyone who got in his way.愿上天降祸于妨碍他的人。Such omens betide no good.这种征兆预示情况不妙。Woe betide him!愿天降祸于他! That was the rule, and woe betide anyone who ignored it.这是规矩,谁不遵守谁就要倒霉。
