Last summer, Idid something really fun. I took part in a project where
young people write stories using AI. Because computers write them,
we had to check to make sure that there were no mistakes in them.
Before I started, I didn’t know that AI can write really good stories.
You imagine that only people can write stories, but AI can give a
helping hand. I was surprised! Most of the stories I read were fine,
but sometimes I found something strange in them. For example,
there was one story where the sun never sets. Of course, that’s not
possible, so I changed that part of the story

Usag
e
We use thePast Simple:
• for actions which happened at a definite or stated time in the past; that is, we
know WHEN they happened.
e.g. They graduated four years ago. (When did they graduate? Four years ago.
We know the time.)
• for actions which happened repeatedly in the past but don’t happen any
more. In this case we can use adverbs of frequency (always, often, usually, etc.)
e.g. He often played football with his dad when he was five.
• for actions which happened immediately one after the other in the past.
e.g. They cooked the meal first. Then they ate with their friends.
