Replacing Italicized Words with Multi-part Verbs:
- I do my homework when I return from school. -> I get up to my homework when I get back from school.
- I'm friendly with my neighbour - we have a lot in common. -> I get on with my neighbour - we have a lot in common.
- I get out of bed late at weekends.
- What do you do when you're out with your friends? -> What do you get up to when you're out with your friends?
Note: The original prompt states 'replace the words in italics', but the provided sentences do not contain italics. The most logical replacements based on the context of Exercise 13 have been made. Sentence 1 is a potential rephrasing; sentence 2 uses 'get on' as a replacement for 'being friendly'; sentence 3 is already a multi-part verb; sentence 4 uses 'get up to' for 'do'.
