The Passive Voice


The Passive Voice
There are seven types of passive voices 
1 General Passive 
2 Modal Passive 
3 Journalistic Passive 
4 Double object Passive 
5 + ing Passive 
6 + going to Passive 
7 + want to Passive 
An active sentence like I drank two cups of coffee has the subject first (the person or thing that does the verb), followed by the verb, and finally the object (the person or thing that the action happens to).
So, in this example, the subject is 'I', the verb is 'drank' and the object is 'two cups of coffee'.
But, we don't always need to make sentences this way. We might want to put the object first, or perhaps we don't want to say who did something. This can happen for lots of reasons (see the explanation further down the page). In this case, we can use a passive, which puts the object first:
·        Two cups of coffee were drunk (we can add 'by me' if we want, but it isn't necessary).
How to make the Passive in English
We make the passive by putting the verb 'to be' into whatever tense we need and then adding the Past Participle. For regular verbs, we make the past participle by adding 'ed' to the infinitive. So play becomes played
Tense
Active
Passive
present Simple
make a cake.
A cake is made (by me).
  present continuous
am making a cake.
A cake is being made (by me).
  past simple
made a cake.
A cake was made (by me).
  past continuous
was making a cake.
A cake was being made(by me).
present perfect
have made a cake.
A cake has been made (by me).
present perfect continuous
have been making a cake.
A cake has been being made (by me).
past perfect
had made a cake.
A cake had been made(by me).
Future simple
will make a cake.
A cake will be made (by me).
   future perfect
will have madea cake.
A cake will have been made (by me).

Verbs with two objects
Some verbs that have two objects can make two different active sentences, and so two different passive sentences too:
Give
·        Active: He gave me the book / He gave the book to me.
You can choose either of the two objects to be the subject of the passive sentence.
·        Passive: I was given the book (by him)/ The book was given to me (by him).
Other verbs like this are: ask, offer, teach, tell, lend, promise, sell, throw. 
The passive in subordinate clauses
You can make the passive in a subordinate clause that has a subject and a normal conjugated verb. This is really the same as a normal passive.
·        Active: I thought that Mary had kissed John.
·        Passive: I thought that John had been kissed by Mary.
·        Active: He knew that people had built the church in 1915.
·        Passive: He knew that the church had been built in 1915.
You can also make the passive using a passive gerund or a passive infinitive in the same place as a normal gerund or infinitive.
·        The child loves being cuddled.
·        She would like to be promoted.
When should we use the Passive?
1.     When we want to change the focus of the sentence:
v The Mona Lisa was painted by Leonardo Da Vinci. (We are more interested in the painting than the artist in this sentence)
2.     When who or what causes the action is unknown or unimportant or obvious or 'people in general':
v He was arrested (obvious agent, the police).
v My bike has been stolen (unknown agent).
v The road is being repaired (unimportant agent).
v The form can be obtained from the post office (people in general).
3.     In factual or scientific writing:
v The chemical is placed in a test tube and the data entered into the computer.
4.     In formal writing instead of using someone/ people/ they (these can be used in speaking or informal writing):
v The brochure will be finished next month.
5.     In order to put the new information at the end of the sentence to improve style:
v Three books are used regularly in the class. The books were written by Dr. Bell. ('Dr. Bell wrote the books' sound clumsy)
6.     When the subject is very long:
v I was surprised by how well the students did in the test. (More natural than: 'how well the students did in the test surprised me')




Passive voice for Present/Future Modals
“CAN, MAY, MIGHT, SHOULD, MUST, OUGHT TO”
·         The places of subject and object in sentence are inter-changed in passive voice.
·         3rd form of verb (past participle) will be used only (as main verb) in passive voice.
·         To change sentences having present/future modal into passive voice, auxiliary verb “be” is added after modal in sentence.

Passive voice of imperative sentences

(command and request)


A sentence which expresses command or request or advice is called imperative sentence. 

Forexample,

      Open ​​​the door.
      Turn off the television.
       Learn your lesson.

For changing these sentences in to passive voice, auxiliary verb “be” is used. The word “Let” is added before sentence in passive voice. Auxiliary verb “be” is added after object in sentence in passive voice. Main verb (base form) of imperative sentence is changed to 3rd form of verb (past participle) in passive voice. For best understand read the following examples.

Examples

Sentences which cannot be changed into passive voice

Transitive and intransitive verb
A verb can be either transitive or intransitive. A transitive verb needs an object (in sentence) to give complete meaning while intransitive verb does need an object (in sentence) to give complete meaning. 
For example,

Transitive verb.
      He sent a letter.
  (Send is a transitive verb and it needs an object i.e. letter to express full meaning.)

Intransitive Verb.

       He laughs.
      (Laugh is an intransitive verb and it does not need object for expressing full meaning.)
    e.g. Sleep, go, reach, sit, die, are examples of intransitive verbs.

Intransitive verb cannot be changed into passive voice
The sentences having intransitive verbs (belonging to any tense) cannot be changed into passive voice. The reason is that there is not any object in such sentences and without object of sentence passive voice is not possible.

A sentence can be changed into passive voice if it has subject and object. Sometimes subject may not be written in passive voice but it does not mean that it has no subject. Such sentences have subject but the subject is so common or familiar or known that if even it is not written in passive voice, it gives full meaning.
For example
Cloth is sold in yards.   
The following tenses can also not be changed into passive voice.
1.      Present perfect continuous tense
2.      Past perfect continuous tense
3.      Future continuous tense
4.      Future perfect continuous tense

Adjectives describe or modify nouns.

Adjectives generally appear immediately before the noun.
  • pretty girl
  • Red flowers
  • long stick
  • Heavy boxes
  • Warm weather
Commonly, adjectives of opposite meaning are formed by adding a prefix such asunin, or dis.
  • clear – unclear, important – unimportant, predictable – unpredictable, believable – unbelievable, common – uncommon, aware – unaware, ambiguous – unambiguous, conventional – unconventional, certain – uncertain
  • definite – indefinite, correct – incorrect, comparable – incomparable, complete – incomplete, evitable – inevitable, expensive – inexpensive
  • able – disable, assemble – disassemble, content – discontent, similar – dissimilar
When using a string of adjectives, they should appear in a set order: size/shape + age + color + origin + material.
  • A big brown house
  • A small old English desk
  • A beautiful black Italian leather purse
  • Delicious Chinese food
The + adjective describes a class or group of people and acts as a noun.

9. Comparative and Superlative Adjectives

Comparative adjectives compare two things. Superlative adjectives compare more than two things

Commonly, adjectives that contain only one syllable or end in 'y' use 'er' to form comparatives and 'est' to form superlatives. For adjectives ending in y, change the 'y' to 'i' before adding the 'er' or 'est'.
  • old – older – oldest
  • young – younger – youngest
  • pretty – prettier – prettiest
  • long – longer – longest
  • short – shorter – shortest
  • bright – brighter – brightest
  • close – closer – closest
  • happy – happier - happiest
Adjectives with two or more syllables do not change but instead add more to form comparatives and most to form superlatives.
  • respectable – more respectable – most respectable
  • beautiful – more beautiful – most beautiful
  • preferable – more preferable – most preferable
  • hardworking – more hardworking – most hardworking
Some adjectives have different forms of comparatives and superlatives.
  • good – better – best
  • bad – worse – worst

The word than typically appears in comparative sentences.
  • Amy is smarter than Betty.
  • Chad is stronger than Dan.

An adverb tells more about a verb in the sentence.

An adverb describes more about an adjective in the sentence.

An adverb modifies another adverb in the sentence.
  • It rains very hard.

Commonly, adjectives can be changed to adverbs by adding 'ly'.
  • slow – slowly
  • quick – quickly
  • comfortable – comfortably
  • loud – loudly
To change adjectives ending in 'y' into adverbs, change the 'y' to 'i' and add 'ly'.
  • happy – happily
  • easy – easily

17. Infinitives Part 2

Commonly, an infinitive is used with the subject it. The sentence structure is "It is                     + infinitive.…" It refers to the infinitive. This expression is used in many ways.

  • It was my pleasure to meet you.
  • It was my honor to have dinner with you.

Both gerunds and infinitive phrases can function as nouns, in a variety of ways. Gerunds and infinitives can follow certain verbs but not others. You need to remember which verbs can be followed by only a gerund or only an infinitive. 

Verbs that can precede only gerunds:
consider, suggest, enjoy, deny, avoid, miss, mind, practice, postpone, resist, finish, quit, give up, put off 
Verbs that can precede only infinitives:
offer, decide, hope, attempt, promise, agree, afford, deserve, refuse, undertake, learn, fail, seem, appear, tend, pretend, choose, demand, desire, guarantee, claim, manage, determine, expect, want, wish
Verbs that can precede either gerunds or infinitives without changing meanings: 
continue, like, love, begin, start, propose, neglect, stand, hate
Verbs that can precede either gerunds or infinitives but change meanings: 
forget, remember, stop, try

6)Do you enjoy                      (take) care of your pet? 

18. Active Voice and Passive Voice

Verbs are either active or passive in voice. In the active voice, the subject and verb relationship is straightforward: the subject is a do-er. In the passive voice, the subject of the sentence is not a do-er. It is shown with by + do-er or is not shown in the sentence.
Passive voice is used when the action is the focus, not the subject. It is not important (or not known) who does the action. 
  • The window is broken. (It is not known who broke the window, or it is not important to know who broke the window.)
  • The class has been canceled. (The focus is on the class being canceled. It is not important to know who canceled it.)
  • The passive voice is often used. (The focus is on the passive voice. It is not important to explain who the writer is.)
Passive voice should be avoided when you want more clarity in writing. However, in some cases, you need to use passive voice to stress the action, not the actor. Also, passive voice can be considered more polite, as it sounds less aggressive or dramatic. 
  • That building was built in 1990.
  • The car was invented about a hundred years ago.
  • I was told that Mary moved to a different country.
  • Your business is appreciated.
  • She was elected to city council.
  • It was rumored that the company would lay off a few people soon.
  • It is recommended that the billing process be shortened.
You can easily rewrite an active sentence to a passive sentence. The object in the active sentence becomes a subject in the passive sentence. The verb is changed to a “be” verb + past participle. The subject of the active sentence follows by or is omitted. 
  • Sam wrote a letter to Jamie.
  • A letter was written to Jamie by Sam.
  • The government built a new bridge.
  • A new bridge was built by the government.
  • I recommend that you apply for this position.
  • It is recommended that you apply for this position.

27. Conjunctive Adverbs

Conjunctive adverbs are words that join independent clauses into one sentence. A conjunctive adverb helps you create a shorter sentence.

When you use a conjunctive adverb, put a semicolon (;) before it and a comma (,) after it. 
  • We have many different sizes of this shirt; however, it comes in only one color.
Some examples of conjunctive adverbs are: accordingly, also, besides, consequently, finally, however, indeed, instead, likewise, meanwhile, moreover, nevertheless, next, otherwise, still, therefore, then, etc. 
  • The due date for the final paper has passed; therefore, I could not submit mine on time.
  • There are many history books; however, none of them may be accurate.
  • It rained hard; moreover, lightening flashed and thunder boomed.
  • The baby fell asleep; then, the doorbell rang.
  • The law does not permit drinking and driving anytime; otherwise, there would be many more accidents.
Conjunctive adverbs look like coordinating conjunctions (and, but, or, so, for, yet, nor); however, they are not as strong as coordinating conjunctions and they are punctuated differently.

A conjunctive adverb is also used in a single main clause. In this case, a comma (,) is used to separate the conjunctive adverb from the sentence. 
  • I woke up very late this morning. Nevertheless, I wasn’t late to school.
  • She didn’t take a bus to work today. Instead, she drove her car.
  • Jack wants a toy car for his birthday. Meanwhile, Jill wants a dollhouse for her birthday.
  • They returned home. Likewise, I went home.

30. Interjections

An interjection is a word that expresses some kind of emotion. It can be used as filler. Interjections do not have a grammatical function in the sentence and are not related to the other parts of the sentence. If an interjection is omitted, the sentence still makes sense. It can stand alone.
  • Ouch! That hurts.
  • Well, I need a break.
  • Wow! What a beautiful dress!
When you are expressing a strong emotion, use an exclamation mark (!). A comma (,) can be used for a weaker emotion. 

Interjections do the following: 

1.Express a feeling—wow, gee, oops, darn, geez, oh:
  • Oops, I’m sorry. That was my mistake.
  • Geez! Do I need to do it again?
  • Oh, I didn’t know that.
2.Say yes or no—yes, no, nope:
  • Yes! I will do it!
  • No, I am not going to go there.
  • Nope. That’s not what I want.
3.Call attention—yo, hey:
  • Yo, will you throw the ball back?
  • Hey, I just wanted to talk to you about the previous incident.
4.Indicate a pause—well, um, hmm:
  • Well, what I meant was nothing like that.
  • Um, here is our proposal.
  • Hmm. You really need to be on a diet.
