第二章 被动语态
一、被动语态的构成
被动语态是由助动词be加及物动词的过去分词构成,如果有需要强调动作的执行者,动作执行者可以由介词by引出的短语表示。助动词be随主语的人称、数、时态和语气的不同而变化。
被动语态中常用的介词
1.by表示动作的执行者或施加者
By whom is the book written 这本书是谁写的?
The children were driven indoors by the rain. 孩子们被雨赶进了室内。
2.with表示用某种工具
The wolf was killed with a gun. 狼被枪打死了。
The field was spread with wild flowers. 田野里野花遍地。
3.from表示源于某种物质(看不出原材料)

4.of表示用某种材料制成(看得出原材料)

5.其他介词
You are wanted on the phone. 有电话找你。
He is known to everybody. 大家都认识他。

注意:
动作执行者可以由介词by引出的短语表示,但被动语态句子中的by短语并不总是表示动作执行者。
