投入是一种状态。像原子核外最外层电子跃入新轨道时所处的激发态;每个人都有过这种感觉,表现为“身自奋袂执锐”,或“忘我”。有时形式即内容。习作分别以句号、感叹号、逗号三种符号为文中小标题,阐述的是“一分耕耘,一分收获”的道理,但表达的效果却令人耳目一新。 Input is a state. The excited state in which the outermost electrons like the atomic nucleus jump into a new orbit; everyone has had this feeling, manifesting itself as “self-invigorating and exquisite” or “ecstasy”. Sometimes the form is content. The three kinds of symbols, the period, the exclamation, and the comma, are the subheadings of the paper. They describe the principle of “one point of cultivation, one point of harvest”, but the effect of the expression is refreshing.
