beat sth. into one's head不要按字面意思把这个短语理解为“把..敲进脑中”，其实这个短语是“重复地让某人学会某事；不断灌输；反复教育某人”。

【例句】
The teacher kept beating the rules into our heads until we could recite them in our sleep.
老师一直不停地向我们灌输规则，直到我们可以在睡梦中背诵出来。

My parents beat into my head the importance of hard work and perseverance.
我的父母不断向我强调努力工作和坚持的重要性。
