knock on the door表示敲门，那knock-on effects呢？
【释义】连锁反应
When an event or situation has a knock-on effect, it causes other events or situations, but not directly.
【例句】
The drought is likely to have a knock-on effect throughout the whole economy. 干旱很可能对整个经济产生连锁反应。
【真题】
If a member of staff considers his or her tasks and duties to be too easy or unchallenging or, in contrast, too diverse or irksome, then he or she will feel dissatisfied, and all the inevitable knock-on effects will manifest themselves – absences, lateness, reduced work-rate and performance, conflict, low morale, or even resignations. 如果公司里的某个职员觉得他/她的任务和职责过于简单、缺乏挑战，或者反言之：过于繁多或令人生厌，那么他/她会感到不满。接下来，一些难以避免的连锁反应就会显现出来：如旷工、迟到、消极怠工、冲突、低士气，或者更有甚者干脆辞职。
