How to paraphrase while writing IELTS essay???

PARAPHRASING
Paraphrasing is simply re-writing a phrase or sentence so that it has the same meaning, but with different words. Paraphrasing is one of the most important skills to learn before doing your IELTS test. It is most important for writing and speaking, but will also help you in the reading and listening tests. In other words, if you know how to paraphrase you are more likely to get the score you need.
Method Number 1: Using Synonyms
Synonyms are different words that have the same meaning. For example, ‘humans’ is a synonym of ‘people’ and ‘attractive’ is a synonym of ‘beautiful’. This method simply replaces words with the same meaning in order to produce a new sentence.
For example:
1. My car needs petrol.
* My vehicle requires fuel.
2. Violent crime is on the rise among teenagers.
*Violent offences are rising among young people.
This student has changed the word ‘teenagers’ for ‘young people’. They are similar words and teenagers are of course young people; however children and young adults, aged between 18-30, could also be described as young people. A more term would be ‘adolescents’ or ‘young people between the ages of 13-19.’ A better way to paraphrase this sentence would therefore be:
Violent crime is on the rise among teenagers. Violent offences are rising among adolescents.

Method Number 2: Change the Word Order
Changing the word order also allows us to effectively paraphrase a sentence, but again, we have to be careful. Don’t change the word order without thinking about how this affects the grammar of the sentence. By changing the word order you may have to add a word, subtract a word or change the form of the word.

Method Number 3: Change the Form of the Word
There are many different forms of words including nouns, verbs, adjectives and adverbs. Changing the form of a word allows us to paraphrase effectively. Again, don’t just change the form of the word; you also need to check that your changes make grammatical sense. You might need to change the words around it to make the sentence error free.
Question: Longer life spans and improvements in the health of older people suggest that people over the age of sixty-five can continue to live full and active lives.
