初中英语语法——被动语态
(1)被动语态定义:被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。如果主语是 动作的执行者(即某人做某事),便叫主动语态;如果主语是动作的承受者(即某事被做),便叫被动语态。主动与被动的区别不是词序的区别,而是主语与谓语意义上的区别。在英语中只有及物动词和一些相当于及物动词的词组才有被动语态的形式。
(2)英语中被动语态由“助动词be +动词的过去分词”构成。助动词be有时态、人称和数的变化。被动语态后的by短语有时可省去。具体结构见下表:
现在时态 一般现在时 现在进行时 一 般 将 来 时 现在完成时
谓语动词构 成 am
is +p.p.
are am
is
+being+p.p.
are will + be+p.p.
am
is +going to+ be +
p.p.
are have(has)
+been+p.p.
过去时态 一般过去时 过 去 进 行 时 过 去 将 来 时 过去完成时
谓语动词构 成 was
+p.p.
were was
+being+p.p.
were would +be+p.p.
was +going
to+be+p.p.
were had
+been+p.p.
[注] p.p.表示过去分词。
(1) 被动语态的用法:
① 不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。如:A man was killed
in the accident.(一个人死于事故)/ This window was broken yesterday.(这扇窗子是昨天被打破的)
②不说或者众所周知是谁做时,用被动语态,省略by短语。如:Rice is also grown in this place.(这个地方也种水稻)/ A railroad will be built here in three years.(三年之后这里将要修建一条铁路)
1 初中英语语法:被动语态
概念:英语有两种语态,主动语态和被动语态。主动语态表示主语是谓语动词动作的执行者或发出者,被动语态表示主语是谓语动词动作的承受者.

助动词be有人称、数及时态的变化;
含有情态动词的被动语态由“情态动词+be+及物动词的过去分词"构成
被动语态的否定式是在助动词后加否定词not;而疑问式是将助动词移到主语前面即可
