Bonjour ! J'ai un petit problème , je dois résumé ce texte en 10 lignes mais je n'y arrive pas ! Voici le texte :

"When Chloe and I arrived on the long sandy beach, it was very hot. There were some people swimming or playing in the waves while others were relaxing under beach umbrellas. The sun was beating down. The deep blue sea in front of us was just so appealing.
Chloe wanted to sunbathe so I decided to go snorkelling on my own. I adjusted my mask and my snorkel, put on my flippers and advanced into the water. It felt so cool after the heat of the beach.
I swam a few yards and I saw the first corals on my left. What a fantastic sight ! The red and purple corals with yellow and blue fish swimming among them, the green seaweeds and the blue water, it was a storm of colours. There were also extraordinary seashells with strange shapes, all this was so unique !
I was admiring all these marvels when something in the distance caught my eye. I swam towards it to see what it was. After a few strokes, I saw the remains of a shipwreck and I decided to have a look. "You never know there might be a treasure in it", I thought.
I was exploring the wreck, looking for hidden treasure when I felt something pass behind me. I turned round but saw nothing. I continued my search for treasure then felt something again. This time I thought I was in danger. I started to worry. I raised my head and suddenly I saw an enormous white form coming towards me."

merci !
