- “He blew up the balloon.” (Object after the phrasal verb)

4. Application in IELTS
Speaking:
In the IELTS Speaking test, using “blow up” can demonstrate your vocabulary range and ability to use idiomatic expressions.
Example question: “Describe a time when you or someone you know got very angry.”
Sample answer: “I remember a time when my usually calm father blew up at a reckless driver. We were on our way to an important appointment when someone cut us off dangerously. My father, who rarely loses his temper, suddenly blew up and started shouting. It was shocking to see him so angry, but I understood his reaction given the dangerous situation.”
Writing:
In IELTS Writing, “blow up” can be used effectively in Task 2 essays or Task 1 reports, depending on the topic.
Task 2 example: “Some people believe that strict punishments for driving offenses are the key to reducing traffic accidents. To what extent do you agree or disagree?”
Sample usage: “While harsh penalties may deter some drivers from breaking the law, this approach alone is not enough to prevent accidents. A more comprehensive strategy is needed before the problem of road safety blows up into an unmanageable crisis.”
Remember to use phrasal verbs judiciously in formal writing, as some may be considered too casual for academic contexts.
