Passive Voice, Causative Voice


10. Passive Voice, Causative Voice
Causative Form, Active and Passive
In English, the causative form is used when we don't do someting ourselves, instead we arrange for someone else to do it for us.
There are two kinds of causative structure:
  • Active Causative
  • Passive Causative

A. Active Causative
Verbs that take active forms of causative are Let, Make, Have, and Get
Let
Let is used when we want to allow someone to do something.
Pattern
let
agent
verb

Example:
She lets me borrow her book.
explanation:

let
agent
verb

She
lets
me
borrow
her book.
Make
Make is used when we want to force someone to do something.
Pattern
make
agent
verb

Example:
My mother makes me do my home work.
explanation:

make
agent
verb

My mother
makes
me
do
my homework.
Have
Have is used when we want to give someone the responsbility to do something.
Pattern
have
agent
verb

Example:
My English teacher has me do the homework in a week.
explanation:
 
have/has
agent
verb

My English teacher
has
me
do
the home work in a week.
Get
Get is used when we want to convince to do something or to trick someone into doing something.
Pattern
get
agent
to
verb

Example:
My friends get me to take the test.
explanation:

get
agent
to
verb

My friends
get
me
to
take
the quiz.
Get vs. Have
Sometimes "get someone to do something" is interchangeable with "have someone do something," but these expressions do not mean exactly the same thing.
Examples:
My friends get me to take the test.
It can be meant that I am actually not encouraged to take the test, but my friends convince me to take that.
My friends have me take the test.
It means that my friends ask me to take the quiz.
B. Passive Causative
There are two verbs generally used in the passive causative form; they are Have and Get. In addition, there is usually no agent in this form; it's not like in active form which has the agent. The action verb is in the past participle, and the object comes before it. The difference between have and get in this passive causative form is the same like in active causative form explained aboved.
Pattern
Subject
Have/Get
Object
Past Participle


Examples:
  • I ask someone to fix my car.
    = I have my car fixed.
  • She asked John to wash the plate.
    = She got the plate washed.

But, if the verb get followed by personal nouns, past participle can't be used in it. Instead, we must use to infinitive. So it will become just like in active causative form.
Pattern
Subject
Get
Object (personal noun)
to
verb

·         I get the house painted
·         I get John to paint the house.

  • You should have your hair cut.
  • He should get his decision changed
  • She will have the food cooked.

Need and want may be used in passive causative sentences. In some cases, the passive causative verb (had/got) may be dropped altogether.??
  • I need/want to have my hair cut.
  • I need/want my hair cut.
