被动语态(Passive Voice)用于强调动作的承受者,而不是执行者。其基本结构为:be + 过去分词(past participle)。
动词 “open” 是一个规则动词,其过去分词为 opened。因此,“open” 的被动语态结构如下:
主动语态:Someone opens the door.
被动语态:The door is opened by someone.
主动语态:They opened the shop at 9 a.m.
被动语态:The shop was opened at 9 a.m.
主动语态:The manager will open the new branch next month.
被动语态:The new branch will be opened next month.
“Open” 的被动语态常用于以下情况:
并非所有含 “open” 的句子都适合使用被动语态。例如,当 “open” 作形容词使用时(如:The door is open.),表示状态而非动作,此时不能转换为被动语态。
✅ 正确(形容词):The store is open.
❌ 错误(误用被动):The store is opened.(除非指“刚刚被打开”的动作)
