被动语态中是先加by sb 还是不定式比如：“I was given a pen by him to write with or“I was given a pen to write with by him“

被动语态中是先加by sb 还是不定式比如：“I was given a pen by him to write with or“I was given a pen to write with by him“ 被动语态的by sb是什么 什么是动词不定式,被动语态,主动语态? send 被动语态send sb sth变为被动时是send to sb sth还是什么？ They have known him___to have been arrested_____(arrest) by the police.划线上为什么用不定式的被动语态啊,应该没有know sb to 还有为什么是不定式被动语态的完成时啊，主要是两点：1.为什么是用不定式 2.为 被动语态中by with什么时候用,比如be made by sb be filled with sth be married to sb和get married to sb是系表结构还是被动语态 不定式的被动语态能不能作状语 变被动语态时,当by sb和时间、地点同时出现时,怎么排列顺序? 被动语态中的介词有哪些,应如何使用?如by+SB. 英语被动语态为啥无宾语by sb是做补语的吗？ see sb.Do sth 及其被动语态 hear sb doing 的被动语态 The teacher……变成被动语态后是by the teacher还是by teacher 被动语态的by sb什么时候不可以省略?通常情况下执行者（by sb.)可以省略,什么时候不可以省略?能举个例子么? Let me listen to you sing the song.改为被动语态You will be listened to sing the song by me.我想问问这个被动句中的to是作为listen to的,还是不定式to sing中的.说是感官动词所接宾语的宾语补足语中的不定式应 think of sb as的被动语态 think sb of 的被动语态 动词不定式的被动语态这句话用英语怎么说
