根据现代心理学，我们必须首先了解“习惯周期”，它是这样工作的:首先，有一个“线索”，一个动作，事件或情况，作为做某事的信号。其次，有一个“常规”，即你对暗示做出反应的常规动作。第三，是“奖励”，我们从日常生活中得到的好东西或感觉。1.modernpsychology现代心理学2.thehabitcycle习惯循环3.takeaction采取行动4.actasasignal充当信号5.inresponseto对……做出反应定语从句定语从句省that的定语从句省that的定语从句Para.3LanguagepointsForexample,whenwefeelunhappy(cue),weeatlotsofunhealthysnacks(routine),which
