英語有两种语态形式:主动语态和被动语态。主动语态表示主语是谓语动词发出动作的执行者,被动语态表示主语是谓语动词发出动作的承受者。这里主要讲一下被动语态的使用方法。
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,人称、数和时态的变化是通过be的变化表现出来的。
一般现在时的被动语态:am / is /are+动词的过去分词;
一般过去时的被动语态:was /were+动词的过去分词;
一般将来时的被动语态:will be+动词的过去分词;
现在进行时的被动语态:am / is /are+being+动词的过去分词;
现在完成时的被动语态:have / has+been+动词的过去分词。
二、被动语态的用法
1. 不知道或没有必要说明动作的执行者是谁。如:
This book was published in 1971.
2. 强调动作的承受者,而不强调动作的执行者。如:
Eight hours per day for sleep must be guaranteed.
三、含有情态动词的被动语态
含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后to仍要保留。如:
This bike can be repaired in two days.
四、使用被动语态时的几个注意点
1. 感官系动词一般用主动形式表示被动意义,如feel, look, seem, taste, sound等。如:
This song sounds good.
2. read, sell, wash, write, wear等作不及物动词时,常用主动形式表示被动意义。如:
This book sells well.
3. 在主动语态中,hear,see等感官动词和make等使役动词后跟不带to的不定式作宾语补足语。但在被动语态中,动词不定式中的to不能省略。如:
They were made to do some housework.
4. 不及物动词没有被动语态。
