請問間接敍述的 when, if ….. (adverbial clause)的內容的人稱和時態需不需要變???
請詳述.
clause 子句裡會涉及finite verb（即是會受tenses） 所影響，是需要變。
直接敘述：
He said, ‘If I were rich, I would buy the house.‘
間接敘述：
He told me that if he had been rich, he would have bought the house.
Reported speech 會向過去退一步，即是：present寫成past，past寫成過去的過去（即past perfect）。would have bought 是屬past perfect的表達形式。
