看绝望的主妇学英语习语:Get back at someone
Get back at someone: To do something bad or unpleasant to (someone who has treated one badly or unfairly); To do something unpleasant to someone because they have done something unpleasant to you; To punish or exact revenge on one in retribution for a past wrong. Take revenge on, as in Watch out for Peter; he’s sure to get back at you.

中文释义:Get back at someone,可不是“回来与某人继续”,意思完全相反,因为某人做了令你不快的事而对他做令人不快的事,惩罚或报复某人,向某人复仇、以牙还牙的意思。如果要表达回来与某人继续这层意思,可以用“get back to sb”这个短语。例句:I’ll get back at him one day(总有一天我会向他报仇的!)
