• shock 本词

Blow and shock can both mean a sudden emotional impact. Blow emphasizes a setback or disappointment that hits hard, usually after bad news. Shock emphasizes the sudden, intense feeling of surprise, which can come from good news or bad. The verb 'blow' is not compared.

两者都指令人猝不及防的强烈心理冲击，但 blow 侧重挫败或失望带来的打击感，常与失败、坏消息相关；shock 侧重震惊、意外的强烈情绪反应，更偏重情绪本身的剧烈程度。这里不比较 blow 的“吹、刮（风）”这一动词义。
