Synthesis of Sentences


Synthesis of Sentences:

The following task is synthesising the sentences which means changing one kind of sentence into another kind.

This kind of practice helps us to understand the sentence structure in full.

1. He must work hard and (he) must make up for the lost time.   Compound Sentence

He must work hard to make up for the lost time.    Simple Sentence

2. He not only robbed the poor child but also (he) murdered her.   Compound Sentence

Besides robbing the poor child, he murdered her.    Simple Sentence

3. Hearing their father’s footsteps, the boys stopped fighting.   Simple Sentence

When they heard their father’s footsteps, the boys stopped fighting.   Complex Sentence

4. She confessed her crime.    Simple Sentence

5. He died in that village. He was born there.   Simple Sentence; Simple Sentence

8. You must hurry or you will miss the train.    Complex Sentence

Sentence Synthesis with specific directions:

1. One of the crew leaped into the water as soon as the boat touched shore.

(direction:  rewrite the sentence using ‘no sooner’)

No sooner had the boat touched shore than one of the crew leaped into the water.

[Note the word order:  ‘touched’ is changed into ‘had touched’  and the first part of the verb ‘had’ is placed before the subject word

‘the boat’ to give the expression more force (emphasis).]

2.  We helped them with money as well as with a gang of workers.

(direction:  rewrite the sentence using “not only…but also’)

We helped them with not only money but also a gang of worker.

3.  The difficulty was solved by means of a special service designed for the occasion.

(direction:  rewrite the sentence making the word ‘service’ the subject)

A special service designed for the occasion solved the difficulty.


Before concluding this topic, the learners must note an important point:

It is not the end of the topic but only the beginning!  Because…

No one single book or course material can include all the rules and important points on any one particular topic.  There are many, many things one needs to learn.  And one learner may understand a particular point more easily than the other.

It is a matter of a particular learner’s ability that determines the time needed to learn a topic!

Some rules are deliberately avoided in this topic just to give the learner some food for thought!

So, come up with your ‘quarries’ and make learning a lively interactive task.

Good  Luck!

Round Up of Sentences [according to Expression]:

Is this a large house?        Interrogative Sentence

Exclamatory Sentence

How beautiful she looks!

What a lovely day it is!

What an awful dream I had last night!

Note the word order of this sentence.  Although the sentence begins with a ‘wh-’ word, it is not an interrogative sentence because the word order is the ‘subject’ first and the ‘verb’ next, just like in the statement sentence.


How beautiful does she look?   Interrogative Sentence

[‘does’ the helping verb of the main verb ‘look’ comes before the main verb “look” – interrogative sentence order; the speaker wants know how she looks]

How beautiful she looks!   Exclamatory Sentence

[‘she’ the subject of the sentence comes before the main verb “looks” – exclamatory sentence order; the speaker says that she looks very, very beautiful]

Imperative Sentence

previous / next

Imperative Sentence:

is a sentence which is used to give orders, advice, instructions, requests and commands.  An exclamation mark (!) is used at the end of this sentence when there is a strong force to the expression, but for the other ‘not so strong expressions’ a full stop (.) is used.


Go away.

Shut up and listen to me!

Help me with these bags, please.

In the examples above, the subject part is not mentioned, i.e. no noun or pronoun is used before the predicate part because any ‘order, advice, command, request, etc.’ is given to the listener (the 2nd person pronoun – YOU) and so, no need to mention it directly.

The subject of the imperative sentence ‘you’ is not mentioned but understood.

However, when the listener is not paying any attention to the speaker or doing something else so there is no chance of knowing that he/she is being addressed, the speaker may use the pronoun ‘you’ to get that person’s attention.


“You there, don’t spit on the floor!”

This way of addressing somebody is considered rude by some people; therefore, we must be careful not to offend others!

‘He got up’ = coordinate clause

‘(he) rushed to the door’ = coordinate clause


‘he rushed to the door’ = main clause

Complex Sentence

previous / next

complex sentence:

is a group of words which has ‘one main clause’ and ‘one or more subordinate clauses’.  The main clause is used without any conjunction but the subordinate clause must be used with any of the subordinate  conjunctions, such as because, as, so, when, who, which, if, unless, where, so that, so…that, though, although, as if, as though, etc.

*Remember that the coordinate conjunctions mentioned in the ‘compound sentence’, ‘and/but/or’, do not belong to this group.

‘He went back home early’ — main clause

‘because’ — subordinate conjunction (included in the subordinate clause)

‘because he was tired’ — subordinate clause (reason)
