Tina是被Paul叫来的。 2.被动语态的基本构成: be + done+(by+动作的执行者） 3.不同时态被动语态的基本结构 一般现在时：am/is/are + done +by sb. 一般过去时：was/were + done + by sb. 现在进行时：am/is/are being + done +by sb. 过去进行时：was/were being + done +by sb. 一般将来时：will be/is going to be +done +by sb. 现在完成时：have/has been + done + by sb. Example: That computer is used by us everyday. That computer was used by us yesterday. That computer is being used by us now. That computer was being used by us at this time of yesterday.
