“耳光”与“血泡”互为表里——如若只有前者无后者,无以凸显“父亲”对“我”“充满希冀”的深情,无以显示“半夜,我跪在父亲床前”的逻辑;但是,如若只有后者无前者——苍白。“血泡”是“骨”;“耳光”是“肉”:相得益彰。此文标题为“耳光响亮”,文眼鲜明;如果拟为“一记响亮的耳光”,文章的“眼睛”就瞎了! “Slap in the face” and “Blood bubble” are both surfaces - if only the former is without the latter, there is no such thing as highlighting the “father” and “I” with a “full of hope”. There is no way to show that “in the middle of the night, I was lying in front of my father’s bed. Logic; but if there is only the latter without the former - pale. ”Bloody“ is ”bone“; ”slap“ is ”meat“: complement each other. The title of this article is ”Sleeping loudly,“ with clear-cut eyes. If it is intended to be ”a loud slap in the face,“ the article’s ”eyes" will be paralyzed!
