The students are decorating the art classroom.
Danny: Look at this yellow star, Brian and Jenny! Isn’t it beautiful I'm going to hang it from the ceiling over the desk.
Brian: Here is the tape. I’ll get the ladder for you.
Danny: I don’t need a ladder. I think I’m tall enough.
Danny can’t reach the ceiling, so he climbs onto Mr Green’s chair.
Danny: Almost... Almost... Aaaaaaahhhh!
After listening
Danny falls.
Mr Green: What was that noise !
He sees Danny lying on the floor.
Mr Green: Danny, are you okay Are you hurt
Danny: Hmm... My tail is a little sore, but it’s not serious.
Then, they hear Brian cry for help, but his voice is very weak.
Mr Green: Brian Where are you
Brian: Help me, sir! I’m under Danny!
Danny: Oh no! I’m really sorry! Are you okay, Brian
Brian: No, I’m the opposite of okay. I tried to catch you, but you landed on top of me. My arm hurts.
Jenny: Should I call an ambulance
Brian: No, that’s not necessary. I don’t think my arm is broken.
Mr Green: Jenny, please call Brian’s mother. Let her know we are taking Brian to the hospital. He should get an X-ray, just in case.
Retell the conversation in Part 2 according to the three processes of “An accident in the art classroom” in Part 3.
Write down your own structure about retelling the accident in Part 2. It must contain the three processes. And you can add some details into each part.
decorate the art classroom
hang a yellow star from the ceiling
climb onto Mr Green’s chair
fall off the chair
land on Brian and hurt his arm
call Brian’s mother
take Brian to the hospital for an X-ray
So at the beginning of the description, we can introduce the background of the accident, like what people there are doing before the accident happens. Then we can describe what leads to the result. And at last, or in the end, we should figure out what the result is and how they deal with the accident.
The students were decorating the art classroom. Danny wanted to hang a yellow star from the ceiling.
Danny thought he was tall enough, so he refused to use the ladder and climbed onto Mr Green’s chair.
Danny couldn’t reach the ceiling well and fell off the chair. Brian tried to save Danny, but Danny landed on top of him.
Brian cried for help weakly because his arm was badly hurt.
Mr Green found them and checked their injuries. Jenny wanted to call an ambulance, but Brian refused.
Mr Green asked Jenny to call Brian’s mother and took Brian to the hospital for an X-ray.
What’s more, to make our description clearer, we can add more real details. For example, why did Danny want to climb onto the chair instead of using the ladder Or why did Mr Green ask Jenny to call Brain’s mother
Work in groups to discuss how we can keep safe in the classroom. Try to write down some sentences.
Don’t climb on chairs or desks in the classroom
Don’t run or push when we are in the classroom
Ask teachers for help when we can’t reach high things
Use all the school tools carefully and safely
