Does someone know if the phrasal verbs can be used in the formal writting part of IELTS/FCE… ?
I used to think that it would be an unappropriate usage of them. However, recently I have seen a tutorial viedeo on how to write an IELTS essay successfully and the author has used the epxression : … to bring about the improvements … (= zaviesť zlepšenia …)
I thought it was not acceptable.
