Knock and criticize both mean to say someone or something is bad. Knock is informal and can sound dismissive, often about things like plans. Criticize is more neutral, used in formal and informal contexts. This does not compare knock's meaning of hitting a door.

这两个词在“说某人或某事不好”这个意义上相近，但语气不同：knock 更口语化，带有随口贬低的意味，常用于评论事物；criticize 语气更中性，正式和非正式场合都适用。这里不比较 knock 的“敲（门）”这一动作义。
