学习者如果不设法设身处地地参与到所学知识的情景中去，就会把所学知识看作是“与己无关”的，因而也就认识不到所学知识的重要性，更不会引起学习者心理上的高度重视，所以学习起来总感到知识枯燥无味，难以掌握。而联系“自我实际”却能化被动为主动，变枯燥无味为生动有趣 If the learner does not try to establish himself and participate in the situation of the learned knowledge, he will regard the knowledge he learns as “unrelated to himself”, and thus will not realize the importance of the knowledge he learns, but will not cause it. The learner’s psychology attaches great importance, so learning always feels knowledge is boring and difficult to master. The link between “self-actual” can turn passive into initiative, and it becomes lively and interesting to become dry and odorless.
