pens…语 态 分 类英语动词有两种语态, 主动语态和被动语态。主动语态表示主语是动作的执行者,如:
They built a new bridge over the river.
被动语态表示主语是动作的承受者,如:
A new bridge was built over the river.当主语是动作的执行者时,随后的动词用主动态;当主语是动作的承受者时,随后的动词用被动态。英语动词的主动态是没有标记的，而被动态则是有标记的，通常由助动词be + 及物动词的过去分词构成。
Many people speak English. (主动)
English is spoken by many people. (被动)结构一般现在时am/is/are+动词的过去分词 一般过去时was/were+动词的过去分词主动语态和被动语态的转换:主: 被:IlearnEnglishEnglishis learnedme+++by被动语态We can use the passive voice when
it is obvious who performs the action.
e.g. Word processing skills are taught
in our computer lessons.
(It is obvious that the person who
teaches word processing skills is
the Computer Studies teacher.) we do not know or do not want to
know who performes the action.
e.g. The printer was sold already.
(We do not want to know who sold
the printer.) we think the action is more important
than the person who performs the action.
e.g. Educational CD-ROMs are sold in
many countries.
(The fact that educational CD-ROMs
are sold in many countries is more
important than knowing who is
responsible for selling the CD-ROMs)We can introduce the person who
performs an action with the passive
voice using “by” and the name(s) of the
person (s) at the end of a passive
sentence.
e.g. That CD-ROM was designed by
Nancy Jackson.Passive voice with “by”Most of us like watching TV. _____ it ________ by you last night?Was watchedIt’s good for us to play basketball.Do you play it as often as possible?____ it_______( play) by you as often as possible? IsplayedVegetables are very important for our health._____they ______ (eat) by you every day?Areeaten把主动语态的宾语变为被动语态的主语,用主格把谓语变为被动结构,注意be 的时态和原句要保持一致。把主动语态的主语放在介词by后作宾语，将主格变为宾格。一、主动语态变为被动语态Conclusion :
