I went to Xiang Shan Park to climb the hill with my friends last winter. It was a good trip at the beginning, but something unexpected happened on the half way. One of my friends got a stomachache and couldn't move any longer. One girl tried to phone her mother with her mobile phone, but there was no signal in the mountain area. Luckily, one of us took some medicine for the trip. We asked him to have a rest by the side of the path.Someone took some medicine and let him have it. Then he drank some water. After a while he felt much better and we walked on.We all enjoyed ourselves at the top of the mountain. 去年冬天，我与朋友们去香山公园爬山。开始的时候非常顺利。走到半山腰时，发生了一件意想不到的事情。一位同学突然胃痛得难以前行。一个女生想给她妈妈打电话，但山上没有信号。幸亏有人带着药。我们让他在路边休息，给他吃了点儿药。后来他喝了水，感觉好多了，我们又继续爬山。在山顶我们都玩得很愉快。 It was very cold and windy, but we still got together at the gate of Xiang Shan Park. Then my friends and I walked toward the top of the mountain. Some boys walked so fast that girls couldn't keep up with them. Everyone was happy and excited. Suddenly, there was something wrong with a girl. She got a bad stomachache and couldn't walk any more. What should we do?We don't know where the hospital was. And nobody took medicine with him. There was only one thing to do that was to let her have a rest by a tree. Just then one of my friends said, "Press the sinus between thumb and index finger." After a while she felt OK. How great the "doctor" Was! We cheered. So we could walk on. 天气很冷还刮着风，但我们仍然相约在香山公园门口。我们向山顶进发。男生爬得快，女生都追不上了。大家都非常愉快、兴奋。突然一个女生胃痛得厉害，无法继续走了。怎么办?我们既不知道医院在哪里，也没有带药。唯一能做的事是让她靠着树休息一会儿。就在那时，一个朋友说：“按着她拇指和食指中间的穴位”。过了一会儿，她觉得好多了。我们都欢呼起来：这个“医生”太了不起了!于是我们继续向山顶进发。
