Jenny was so excited. She looked forward to her winter holiday in the Swiss Alps all year and now she was finally there. There were lost of interesting people in her group and the leaders seemed very professional and experienced. Jenny couldn't believe her luck. She was away from the city at last.
Everyone was amazed by the scenery on their first walk. The snow-capped moutains looked beautiful against the clear blue sky and the air was so fresh. There were colorful wild flowers everywhere. Jenny stopped to take some photographs. But, when she looked around she realised that everyone else had gone and she was completely alone!
Some time later jenny was walking along the track, when suddenly she saw that it divided into two paths and didn't really know which one to take. She decided to follow the path on the right. After a while there was a noise and the ground sank. She screamed as she felt herself falling over the edge of the mountain, but managed to grab some bushes oh her way down. She shouted as loud as she could, but no one came.
Then, just as she was losing, she felt two strong hands pull her to safety. Thankfully, the group leaders quickly realised she was missing and went back for her. Jenny was so relieved that they found her just in time!
