reason后用which 还是 why

reason后用which 还是 why
reason后用which 还是 why

reason后用which 还是 why
要看具体情况,给你举个例子：
1.Here is the reason-----he gave me.这个中间要用which,而不能用why.
2.here is the reason-----he was late.这个中间要用why 而不能用which.
明白吗?

有语感后会习惯the reason why

你好:
用 Why 这是固定用法 比如 : He refused to explain the reason Why he failed the exam.
