在古代很长的时间里,人们一直以为是用心脏来思考和学习的。后来,随着经验的积累和科学技术的进步,才发现指挥这些心理活动的,不是心脏而是脑子。人脑是整个身体的“最高司令部”,人脑是思考和学习的器官。由于积习相沿,现在人们在日常谈话中,还常说“学习要用心”、“专心致志”、“牢记在心”等等,用“心”来代替“脑”。 In ancient times, people used to think and learn from their hearts. Later, with the accumulation of experience and the advancement of science and technology, it was discovered that it was not the heart but the mind that directed these psychological activities. The human brain is the “Supreme Command” of the entire body, and the human brain is the organ of thought and learning. As a result of accumulating experiences, people nowadays often use “heart” instead of “brain” in daily conversation. They often say “study hard”, “concentrate on their minds”, “keep in mind” and so on.
