新聞常看到「〜を余儀なくされる」，主詞永遠都是「被逼」的那一方嗎？

Question

看地震新聞的時候常看到「住民は避難を余儀なくされた」。這句子文法上是不是一定要用「被動+余儀なくされる」的組合？可以說「余儀なくする」讓某人做某事嗎，還是這個文型本質上就是單向的（永遠是「被迫」）？

Accepted Answer

余儀なくされる is already the passive-leaning form and is what you'll see 95% of the time in news reporting — the subject is the one forced into the situation by outside circumstances (disaster, policy, illness). The active 余儀なくさせる does technically exist ('to force someone into'), with the circumstance/cause as the grammatical subject, but it's much rarer and reads more formally/legally.
