A Terrifying Experience
"If mum finds out that I'm going to the beach, I'll be in big trouble." I muttered(嘟囔)to myself softly.
I crept slowly down the stairs and tried to walk casually into the kitchen. As I was walking towards the back door, mum asked without looking up from her "dish-washing", "Where are you going?" I answered back without hesitation, "I'm going to the garden to play." After I got out of the kitchen, I breathed a sign of relief. My plan had worked out fine so far. I scaled(攀爬)the fence and jumped onto the muddy field next to my house and started running towards the bus-stop at top speed.
After half an hour, I was at the beach scanning the crowd for my friends, Jimmy and Bobby. After a while, I spotted them near a coconut tree. I ran towards them and got into my swimming trunks(泳裤). For about an hour, we played volleyball happily.
Suddenly, Bobby hit the ball too hard and the ball fell into the sea. Just as Bobby was going to pick up the ball, the tide came in and carried the ball further and further away from the shore. I wanted to show off my swimming skills so I decided to get the ball for them.
I dived into the water and started swimming at a steady pace. After swimming for about ten minutes, I became tired but when I saw that the ball was only a few feet away from me, I put in an extra burst of speed. However, just as I was going to grab the ball, a very strong current swept the ball further away from me. At that moment, a string of weed tangled(缠绕)up with my feet and l could not swim properly.
I struggled to keep afloat but it was no use. "If I had listened to mum and dad, this would never have happened," I thought silently.
