Travelling not only opens my eyes to the world but also makes me strong. I love travelling. I love hiking (徒步旅行) best. Last week, I 1 with my friends. It was a very famous place for its beautiful sightseeing, and all of us were very 2. It was a good trip at the beginning, 3 something unexpected (意想不到的) happened on the half way. 4 of my friends suddenly felt a terrible pain in his stomach and he couldn't 5 any further. We were worried, but nobody knew 6 to do. One girl tried to call her mum with her mobile phone, but there was no signal (信号) in the mountain area. Luckily, we brought a 7 with us. We put it up quickly and let him 8 in it. He took some medicine. Then he drank some water and ate some food. After a while, he felt much 9 and then we walked on. When we got a bird's—eye view of the beauty, we all enjoyed ourselves 10 the mountain.
