Transformation of Sentences

Changing the form of sentences without changing the meaning is called thetransformation of sentences.The nature of the sentences can be changed without changing the meaning of the sentences. 

Transformation of Sentences is done in various ways. The major transformations are done via interchange of –


Note: We have already studied the first two (Active-passive) and (Direct-reported speech). Here we would cover the other types of transformations.


1. Sentences Containing the Adverb ‘too’:  

Transformation: ‘too’ is replaced with ‘so …. that’

The transformation of sentence takes place by removing the adverb ‘too’ and by adding a conjunction ‘so…that’. In this way, the following sentences have been changed for your revision. 

For example, two sentences are given:

The tree is very high. I cannot climb it.

We can combine the above sentence in two ways –

The tree is too high for me to climb.
The tree is so high that I cannot climb it
.

Now study the following examples:

Example 1:  

My friend is too rich to be my consort.
My friend is so rich that he cannot be my consort. (Transformed)

You can see how the Transformation of Sentences, containing the adverb ‘too’, takes place without changing the meaning of the sentence.  

Example 2: 

The news is too good to be true.
The news is so good that it cannot be true. (Transformed)

Example 3:  

He drove too fast for the police to catch.
He drove so fast that the police could not catch him. (Transformed)

More Examples:  

  1. He is too proud to beg.  
    He is so proud that he will not beg.  
  2. It is never too late to mend.  
    It is not so late that it cannot be mended.  
  3. He is too ignorant for the post of a postman.  
    He is so ignorant that he is not suitable for the post of a postman.
    OR
    The postman is so ignorant that he cannot be fit/suitable/selected/ for the post of a postman.  
  4. This shirt is too small for me.  
    This shirt is so small that it is not suitable for me.  
  5. He speaks too fast to be understood.  
    He speaks so fast that he cannot be understood. 

2. Interchange of Degrees of Comparison

Positive – Comparative – Superlative Degrees

The Transformation of Sentences, containing comparatives, can be done as follows without changing the meaning of the sentences.

We can change the form of sentences into their possible transformations by interchanging them between positive – comparative – superlative degrees.

Examples; Interchange of Positive and Comparative Degrees.

Note: Interchange into superlative degree is generally not possible when two specifics items of comparison are involved. For example, in the first sentence above, comparison is between only two – ‘I’ and ‘you’. in the third sentences between ‘Reena and Poonam’.

PositiveI am as tall as you.
Comparative You are not taller than me.
PositiveI am as strong as him.
Comparative I am not stronger than him. OR. You are not stronger than me.
ComparativeReena works harder than Poonam.
PositivePoonam does not work as hard as Reena.
ComparativeThat razor is sharper than this one.
PositiveThis razor is not as sharp as that one.

Examples: Interchange of all the three Degrees of Comparison

Note: Interchange into all the three degrees of comparison is possible when more than ‘two’ entities are involved. Example: In the first sentences, ‘Mumbai’ is compared to many other cities in India i.e. more than two cities are involved in the comparison. same is with the second example where ‘Reena’ is compared with all the other girls in the class i.e. more than two girls are involved.

PositiveVery few cities in India are as rich as Mumbai.
ComparativeMumbai is richer that most other cities in India.
SuperlativeMumbai is one of the richest cities in India.
SuperlativeReena is one of the best girls in the class.
ComparativeReena is better than most other girls in the class.
PositiveVery few girls in the class are as good as Reena.
SuperlativePoonam is not the tallest girl in the class.
ComparativePoonam is not taller than many other girls in the class.
PositiveMany girls in the class are not as least tall as Poonam.

3. Interchange of Affirmative and Negative Sentences:

While transforming the sentences it should be kept in mind that the meaning should not change.

  • The affirmative sentence can be changed into a negative sentence by using ‘no or not’.
  • The ‘not’ in the negative sentences should be removed to convert them into affirmative sentences.

Examples:

AffirmativeHe has courage
NegativeHe is not without courage
AffirmativeEverybody is present.
NegativeNobody is absent.
AffirmativeAll cheered.
NegativeThere was no one present who did
not cheer.
AffirmativeI was doubtful whether it was you.
NegativeI was not sure that it was you.
NegativeNobody denies it.
AffirmativeEverybody admits it.
NegativeGod will not forget the cry of the humble
AffirmativeGod will heed the cry of the humble.

4. Interchange of Interrogative & Assertive Sentences

Transform but do not change meaning. An interrogative sentence can be transformed into an assertive sentence and vice-versa.

Examples:

InterrogativeWho does not know him?
AssertiveEveryone knows him.
InterrogativeWhen can their glory fade?
AssertiveTheir glory can never fade.
InterrogativeWas he not a villain to do such a deed?
AssertiveHe was a villain to do such a deed.
InterrogativeWho can touch ditch without being defiled?
AssertiveNo one can touch ditch without being defiled.
InterrogativeIs this the kind of dress to be worn for a school function?
AssertiveThis is not the kind of dress to be worn for a school function.
AssertiveWe were not sent to this world simply to make money.
InterrogativeWere we sent to this world simply to make money?
AssertiveI never forget those happy days.
InterrogativeShall I ever forget those happy days?

5. Transforming Exclamatory sentences into an Assertive sentence:

Sentences expressing strong feelings are called exclamatory sentences. The exclamations can be of wow or despair feelings. The mark of exclamation ‘!’ ends such sentences.

  • Exclamatory sentences are transformed into assertive sentences by converting them into a statement.
  • Remove any ‘Q. word’ (like – ‘How and What’) or ‘conditionals’ (like – ‘if’) used in the beginning of the exclamatory sentence.
  • Add some modifier if needed like – ‘very’
  • Insert, if required, a proper verb like – ‘wish’, ‘pray’
  • Insert, if required, subject by yourself using pronouns in third person.

Examples:

Note: The ‘modifiers and inserted words are shown in italics.

ExclamatoryAssertive (Statements)
1. How lovely the garden is!The garden is very lovely.
2. What a terrible noise!
OR What a terrible noise it is!

3. How sweet the moonlight sleeps upon the riverbank!The moonlight sweetly sleeps upon the river bank.
4. If only I were young again!I wish I were young again
5. What a delicious meal!This meal is delicious one.
Transformation of Sentences

6. Transforming the Simple sentence into a Compound sentence:

A simple sentence can be transformed into a compound sentence by enlarging a phrase or word into a co-ordinate clause i.e. the clauses of equal rank.

The coordinating conjunctions are used to join coordinate clauses.

In the following Examples Coordinating Conjunctions are shown in colours.

Simple SentenceCompound Sentence
1. He must work hard to make up for the lost time.He must work hard and make up the lost time.
(This sentence can be made into two parts and
those two parts can be joined by a conjunction
‘and’)

Transformation of Sentences

8. Transforming a Simple sentence into a Complex sentence:

A simple sentence can be transformed into a complex sentence by enlarging a phrase into a subordinate clause i.e. the clauses of unequal rank – a mix of principal and subordinate clauses.

The clause maybe Noun, Adjective or Adverb.

Must Remember ➡A simple sentence comprises only one clause and therefor it is broken into more than one clause to convert it into a complex sentence because a complex sentence comprises more than one clause.

Simple SentenceComplex Sentence
1. He confessed his crime.He confessed that he was guilty of the crime.
(Here the noun (his crime) has been changed into a subordinate clause.)
2. On the arrival of the mails, the steamer will leave.The steamer will leave as soon as the mails arrive.
(Here the adverbial phrase ‘on the arrival of’ has been changed into a subordinate clause.)
3. I saw a wounded bird.I saw a bird that was wounded.
(Here the adjective phrase ‘a wounded bird’ has been changed into a subordinate clause.)
4. On being punished, he wept.When he was punished, he wept.
Transformation of Sentences

9. Transforming a Complex sentence into a Simple sentence:

A simple sentence comprises only one clause.

A complex sentence comprises more than one clause and therefore, to make it a simple sentence it needs to be combined in such a way that it contains only one clause which is a principal clause with a subject and a predicate.

In the following examples –

  • The subordinate clauses of complex sentences are shown in blue italics.
  • See how the subordinate clauses are changed into phrases (in coloured italics) to make a simple sentence with a single clause – Noun Clause or Adjective Clause or Adverbial Clause.
Complex SentenceSimple Sentence
1. He said that he was an innocent.He declared his innocence.
2. How long I will stay is doubtful.The duration of my stay is doubtful.
(Here, the Subordinate Clause ‘how long I will stay’ has been changed into a noun phrase or a noun clause – a single clause makes a simple sentence.)
3. Tell me where you live.Tell me your address.
4. He died in the village where he lived.He died in his native place.
(Here the Subordinate Clause has been changed into an Adjective Clause.)
5. The moment that is lost is lost forever.The lost moment is lost forever.
6. He was so tired that he could not stand.He was too tired to stand.
7. He will not pay unless he is compelled.He will pay only under compulsion.
Transformation of Sentences

10. Some Other Examples of Transformations

The verb of a sentence itself can be changed into another verb without (changing) the meaning of the sentence.

Remember that the meaning of the sentence should not change while transformation.

This kind of jokes never amuses me.
This kind of joke never gives me any amusement.
