whether可以引导条件状语从句吗

Question

如题所述

Answer 1

可以， 比如
Whether you hear from him or not, you must still go.
Whether the result is favorable or not, you should speak the truth.

Answer 2

需知道whether引出的句子其实是选择疑问句变通成为从句的模式，如；Will he come here or not?变通，'Whether he will come here 'is not known.或I don't know whether he will come or not.注意；只有当whether从句位于复合句中间的时候，可以换用if引出从句，但if本身不会等于whether...or not结构。换句话说，if从句位于主句及物谓语之后是宾语从句，也就是名词性从句，如；I don't know if he will come=I don't know whether he will come.
