    I/Passive voice (P.V): is usually to emphasize the result, the fact or the object of an action ,not the agent.

    *P.V is used only with Transitive Verb
    *P.V is used more commonly in written language , especially in the impersonal style of textbooks or report ( to describe an industrial and scientific process, to describe historical and social process or in official rules and procedures)

    Ex :
    The ore is usually dug out of the ground.
    Applications should be made in writing.


    General form :
    S+Vt+O ( Vt= transitive verb)
    -->PV:S(o) + be + P(2)+ (by O)


    *to be in passive sentence is always in the same forms and tenses & main verbs in the active sentence.

    In P.V:

    *To verb is changed into to be P(2)

    *Verb is changed into be P(2)

    *V-ing is changed into Being P(2)

    *Modal verbs work in the same way :
    S+ modal verb + Vt+ O

    ->P.V : S(o)+modal verb + be+P(2) + (by S)

    Ex :
    The windows in being painted .
    The machine can be taken apart.

    BASIC USES of passive voice

    I/Agent and instrument:

    *Agent : A person who does the action in the Passive sentence is called the agent
    *Instrument : Things which cause something to happen in a passive sentence is called an instrument .

    I was hit by a branch ( The branch itself hit me)
    Iwas hit with a branch ( Some one use a branch to hit me ).

    II/Transitive and intrasitive verbs :

    1/Transitive verbs are the verbs with object.

    There are 3 kinds of Vt( verb transitive )

    ---[b]Memo-trasitive verbB] : verb with 1 object (read, write,...)
    ---Di-transitive verb :verb with 2 objects(give, bring,pay,hand,show...)
    ---Complex transitive verb

    I read the newspapers yesterday.
    I gave her a present.

    --All Vt.s can be made passive except :become, have, get, suit, fit, resemble.

    2/Intrasitive verbs are verbs with no object :

    The baby is sleeping.
    The bird flies.
    3/Some verbs are both transitive and intransitive verbs . "run" for example :

    Ex :
    He ran a shop --> A shop was run by him .
    He is running --> (no passive)

    * In this case, we focus on transitive verbs
    III/Cases of omitting the agent.

    1/When the agent is general : people, they, you , we .

    *When these sentences are made passive , these general agents can be omitted because they doesn't give more information .

    All over the world, people respect the knowledge
    -->The knowledge are respected all over the world .

    2/ When the agent is obivious :

    *In Passive sentences , when all people understand who do/does the action, then there is no need to mention the agent again .

    Ex : The criminal was arrested ( by the police)

    3/When the agent is unimportant( we don't need to know about the agent)

    I was advised to worked harder.

    4/When the agent is unknown ( we don't know anything about the agent)

    She was killed yesterday

    5/When both speakers and listeners know the agent

    I was tested thoroughly.

    6/When the speaker doesn't want to mention the agent. Then the agent is omitted.

    Ex :
    It has been agreed to increased the salaries by 5%

    7/When the speaker want to focus on the action rather than the agent

    Mails are delivered to whom addressed
    Verbs with 2 objects

    -This kind of verbs can also be called the Verbs of giving because thet have the same pattern as " give"
    -In this case, either of these objects can be the subject of a passive sentence
    -We will use the object which we want to emphasize to be the subject of the passive sentence .

    The nurse gives the patient a sleeping pill
    --> The patient is given a sleeping pill
    --->A sleeping pill is given to the patient .

    Other Verbs can be used in this pattern Cuối bài có file đính kèm 1 số động từ dùng như cách của động từ " give ")

    Verbs with Object and Complement

    -This kind of verbs is also called complex transitive verbs. There are some verbs such as: make , find.

    *It made me ill
    --> I was made ill
    *People found he had died
    --> He was found dead

    Passive with " want" and "need"

    -If the sentence follows the first structure , we have to make it passive like the second.

    S+want/need+ O(1)+ to - infinitive+ O (2)

    ---> Passive : S+ want/ need+ O (2)+ to be Past participle + by O(1)

    Ex : He wants her to take a photo
    -->He wants a photo to be taken
