the one和that用于定语从句中有何区别?举例解释,详细点例如；Is this book the one you left on the bus yesterday?(为什么不能换成that?)

明确告诉你，引导定语从句只能用that
Is this book the one you left on the bus yesterday?由于先行词the one做定语从句的宾语，可以省略that
Is this book the one （that）you left on the bus yesterday?
Is this the school that you visited last year?(为什么不能换成the one ？）因为引导定语从句的引导词就没有the one
