2023年成人高考-专升本英语-被动语态.docx

被动语态一、知识点回顾（一）被动语态的构成被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的 形式，过去分词部分不变。疑问式和否定式的变化也如此。（二）被动语态的用法1 .不知道或没有必要指出谁是动作的执行者时要用被动语态。2 .当更加强调动作的承受者时要用被动语态。此时动作的执行者由by引导，置于谓语 动词之后，不需要时可以省略。These books may be kept for two weeks.这些书可以保管两周。3 .当动作的执行者不是人时，多用被动语态。The window was blown by wind.窗户被风吹开 了。4 .表示客观的说明常用“It is+过去分词+that”句型。It is said that Lucy has gone abroad.据说露西已经出 国了。二、习题练习1.
