英语中的时态有多种,但语态只有两种,即:主动语态和被动语态。被动语态由“be + 及物动词的过去分词”构成,其主语是动作的承受者。
一、被动语态的构成

二、使用被动语态须注意的几个问题
1. 被动语态有时也可由“get + 及物动词的过去分词”构成。如:
She rushed out of the door as soon as she got dressed.
2. 不及物动词无被动语态。如:rise, appear, die, disappear, fail, happen, last, remain, sit, spread, stand等。如:
[误] The price has been risen.
[正] The price has risen.
[误] The accident was happened last week.
[正] The accident happened last week.
3. 系动词无被动语态。如:be, become, feel, get, smell, sound, seem, taste等。如:
That music sounds good.
4. 某些及物动词或短语动词也不用于被动语态。如:cost, fit, hold, own, wish, notice, watch, break out, come about, come true, take place等。如:
This key just fits the lock.
I hope your dream will come true.
5. 某些动词(如:read, sell, wash, clean, lock, write, draw, shut, wear, cut, write等)与副词well, badly, easily等连用表示性能时,常用主动表被动。如:
This pen writes well.
This knife cuts easily.
6. 在need, require, want, worth(adj.),deserve等后的动词?鄄ing必须用主动形式来表示被动(相当于不定式的被动式)。如:
This book is worth reading (= to be read).
Eric, don’t you think your clothes need washing (= to be washed)?
