关于whose引导的定语从句的疑问。
一道翻译题：如何保护我们的实力是个重要的问题，每个青少年都应该知道答案。
参考答案是：How to protect our eyesight is an important question whose answer to every teenager should know.
为什么有了whose还要加to？ 还原回去不是the question's answer吗？或者该用to which the answer?
可以直接写every teenager should know的主动形式，而不是should be known by every teenager吗？

Answer 1

你问得非常好！要么 How to protect our eyesight is an important question whose answer should be made known to every teenager，要么 How to protect our eyesight is an important question to which every teenager should know the answer。
可以直接写 every teenager should know的主动形式吗？—— 可以，见上面的句子。
