2020年冀教版八年级英语下册Unit7 如何把主动语态转换为被动语态
Unit7 如何把主动语态转换为被动语态语态是动词的一种形式，用来说明主语和谓语动词之间的关系。
其中主动语态表示主语执行动作，被动语态表示主语承受动作。
那么，怎样把主动语态转换为被动语态呢？1. 先确定主动句的主、谓、宾，找出其谓语动词；2. 把主动句中谓语动词后面的宾语变为被动句的主语，若宾语是人称代词时，应把宾格变为主格；3. 把主动句中的谓语动词变为“助动词be + 及物动词的过去分词”结构，但时态不能改变；4. 把主动句中谓语动词前面的主语变为被动句中介词by的宾语(没必要说出动作的执行者时可略去“by + 宾语”)，若主语是人称代词时，应把主格变为宾格。
友情提示：1. 如果主动语态中含有动词短语变为被动语态时，不可丢掉短语末尾的介词或副词。
如：You can look up this word in the dictionary. →This word can be looked up in the dictionary.2. 使役动词make, have及感官动词see, hear, watch, feel等后接省略to的不定式作宾语补足语的主动语态变为被动语态时，动词不定式的符号to还要加上去。
如：The boss made them work for 16 hours a day. →They were made to work for 16 hours a day (by the boss).We saw them work in that workshop. →They were seen to work (by us) in that workshop.3. 如果主动语态的句子中含有双宾语变为被动语态时，有两种方法：①将指人的间接宾语作被动语态的主语时，要将人称代词宾格变为人称代词主格，指物的直接宾语保留不变；②将指物的直接宾语变为被动语态的主语时，间接宾语保留不变，但要在其前加介词for或to。

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.
"The project will be completed by next week."

主动变被动解题步骤: 1. 找宾语 ----即动作的承受者 2. 判断宾语的单复数 ----即be动词的单复数. 3. 判断动词的时态 ----即be动词的时态. 4. 修改谓语的时态 ----即原句动词改为过去分词 5. 修改原句的主语 ----即by+ 主语.
