You are wanted on the phone. 【误】Xiao Wang, come here. You are being wanted on the phone. 4、其他形式表示被动结构 “be+under/in等介词+名词”结构可代替进行时被动语态。例： The city is under attack(is being attacked)at the moment. 目前这个城市正受到进攻。 The bridge is under repair/construction. (=is being repaired/constructed). 桥梁正在修理中/建筑中。 The problem is under discussion(=is being discussed)at the meeting. 问题正在会上讨论。 The telephone is in use(=is being used) now. 电话正在使用中。语法专练1. Hurry, Mary!
