【探究总结】 (1)现在完成时的被动语态的两个部分,即have/has和been,两者缺 一不可。 (2)与一般过去时的被动语态的区别:一般过去时的被动语态强调 发生在过去,不强调动作或状态与现在的联系,而现在完成时的被 动语态则强调与现在的情况有联系。 (3)非延续性动词,如borrow、 finish、 begin、 start、 buy、 marry、 open、 join等构成的现在完成时的被动语态不能与表示一段时间 的状语连用。若要表达相应的意思,则要改换动词或时态。 (4)短语动词是一个不可分割的整体,在被动语态中要保持完整性, 其中的介词或副词不可省略。
当动词为非延续性动词时,可与_a_l_r_e_a_d_y_或___y_e_t__连用,但不
能与for或since引导的表示一段时间的状语连用。 【应用实践】 单句改错。 ①The club has been founded for five years. ____________________________________________________ ②My report has been handed in for a week. _____________________________________________________
