Rewrite the sentences using the causative

To transform the sentences using the causative structure, typically the format is "subject + have/get + object + past participle." Here's how you can rewrite each sentence: 1. Someone is going to check my homework. - I **am going to have my homework checked**. 2. My mum’s phone was repaired a few days ago. - My mum **had her phone repaired** a few days ago. 3. They installed a new alarm in the school yesterday. - The school **had a new alarm installed** yesterday. 4. A friend cut my sister’s hair. - My sister **had her hair cut** by a friend. 5. A new IT centre is being built at the college. - The college **is having a new IT centre built**. These sentences now reflect the causative form, which indicates that the subject arranged for someone else to perform the action.
