Why are you so happy today? Because I have been chosen to be the chairperson.
此段对话的回答部分中的have been chosen为什么不能换成was chosen?
因为强调I have been chosen to be the chairperson对现在的影响是使我高兴
而不是只为说I have been chosen to be the chairperson这个动作的发生
用完成时可以强调对现在的影响,即“Why are you so happy today”,而单纯的过去时没有这层含义,所以选have been更好。“Why are you so happy today”是本题的题眼
表示过去发生对现在产生了影响(so happy today这个影响) 所以用have been chosen
完成时表示过去的动作对现在的影响,我不是很高兴吗?
表达了他为此感到很高兴,并且意义很大。若对现在或将来有深渊影响或持续的影响,那么就选择用现在完成时,比单单只能强调动作的过去的过去式,更好,懂么。
