How do we paraphrase?
There are many techniques we can use,but essentially paraphrasing can involve three main features:
1.Changing word class(e.g. verbs to nouns)
2.Changing vocabulary(e.g. using synonyms)
3.Changing grammatical structure / word order(e.g. cause and effect;active to passive)
As well as these three techniques,we can also change the reporting verb and / or the way the in-text reference is used.
