Have something done
Have or get something done: when someone else does a job for you – and when something bad happens to you.

Who cut your hair? Not you! When someone else does something for you, English uses have or get + object + past participle. It's a Part 4 favourite.

How it comes up in Part 4
In Part 4 you complete the second sentence with the key word, so that it means the same as the first one (2–5 words).
HAVING
I'm having my car repaired tomorrow.
Someone else does the job → have + object + past participle, in the same tense (present continuous for a plan).
HAD
She had her bag stolen on the train.
Something bad happened to her → had + object + past participle.
GET
You should get your eyes checked .
Get + object + past participle means the same as have.
Common mistakes
- ✗ I cut my hair yesterday. (at the hairdresser's)✓ I had my hair cut yesterday.'I cut my hair' means you did it yourself.
- ✗ I had cut my hair.✓ I had my hair cut.The object goes between have and the past participle.
- ✗ I got my brother help me.✓ I got my brother to help me.Get someone + to-infinitive; have someone + infinitive without to.

In Part 4, when the first sentence says someone else did something for you (a mechanic, a hairdresser, 'someone'), think have / get + object + past participle – and keep the tense of the first sentence.
