八年级英语下学期被动语态
初二被动语态
被动语态讲解一、各种时态的被动语态一般现在时：am／is／are＋动词过去分词Cars are made by them。
一般过去时：was／were＋动词过去分词The MP3 was bought by my father。
一般将来时：will/shall/be going to be＋动词过去分词The bridge will be completed in ten days.现在完成时：have／has been＋动词过去分词The meeting has been put off。
二、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。
歌诀是：情态动词变动，情态加be加“过分”.例如:we can repair this watch in two days. →This watch can be repaired in two days.We must finish this work soon。
→This work must be done soon.We have to clean the classroom。
→ The classroom has to be cleaned by us。
三、主动语态变被动语态需要注意的几个问题.（1)时态保持一致.I have repaired my computer。
-—-My computer has been repaired.（2）如果要说出动作的执行者，并且这个执行者可以作主动语态中主语时，就用by短语，如果后面的词表示地点，不是动作的执行者,就用in短语.It is made by us. It is made in Wuhan。
(3）主动句的主语是代词的主格形式，变成被动句by的宾语时要用其宾格形式.He cleaned the car. → The car was cleaned by him.(4）疑问句的被动语态，用be动词的对应形式代替doDoes she drive this car? →Is this car driven by her?（5）谓语为动词短语的被动语态不能丢掉动词短语的介词或副词。

Unit7 语法--被动语态 Passive voice 讲义--牛津译林版英语八年级下册
被动语态 Passive voice 第一讲Part 2【被动语态】一、概念语态是动词的一种形式,表示的是主语和谓语之间的关系。
，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,被动语态表示主语是动作的承受者。
Eg. ①They built a new bridge over the river. (主动) →A new bridge was built over the river by them. (被动)①Many people speak English. (主动) →English is spoken by many people. (被动)二、被动语态的基本用法被动语态由助动词be＋过去分词构成,时态通过动词be表现出来。
We use the active voice when it is important to know who performs the action.(1) it is obvious who performs the action动作的执行者是泛指或不言自明时：Eg. None of the books was taken away.(2)We do not know or don’t need to now who performs the action在不知道或没有必要知道动作的执行者是谁时：Eg. The toy is designed for children.(3) the action is more important than the person who performs the action需要强调动作的承受者Eg. Rice was first grown in China.【拓展】(4)出于礼貌或委婉而避谈动作的执行者。
Eg. This problem was talked about just now.(5) 在被动语态句子中,如果我们需要指出动作的执行者,可以由by引出。

03 The Usage of Passive Voice
Not knowing or needing to know the situation of the action executor
The passive voice of sensory verbs can also be used when the subject is not mentioned or is unimportant. For instance, in the sentence "The letter was written," the subject of the verb "write" is not mentioned.
The passive voice of phrasal verbs is often used when the focus is on the action rather than the agent. In the sentence "The package was sent by him," the emphasis is on the action of sending rather than the sender.
The subject is often omitted in passive voice sentences, and the verb "to be" is also omitted.
The retention of be in passive voice
In some cases, the verb "to be" is retained in passive voice sentences.
