原文：
She said helping others changed her life.
Teaching high school students in a poor mountain village in Gansu Province may not sound like fun to you.However,it changed the life of Yang Lei from Beijing.The Peking University graduate first went there as a volunteer on a one-year program.The program was started by the Ministry of Education and the Chinese Young Pioneers.Every year they send 100 volunteers to teach in China's rural areas.
Life in the mountains was a new experience for Yang Lei,Her village was 2000 meters above sea level,and at first the thin air made her feel sick.The food was very simple——teachers ate porridge three times a day.Fortunately,Yang Lei's mother agreed with her daughter's decision.She said that both she and her husband thought this was a good idea."Young people today need to experience different things,"she said.
Most of the pupils live in school dormitories.They work very hard.They get up at 5 am and read books until 11 pm.They love having the volunteer teachers there."There is no difference between you and them,"saya Yang Lei."They say that we are like big brothers or sisters to them,and they feel lucky."
Many children may not be able to go to senior high school or college.Families are poor and there often isn't money for education."I can't do anything about that ,but I can open up my students' eyes and give them a good start in life.She said she likes being a good influence in their children's lives.
Yang Lei enjoyed her times as a volunteer very much.When her year was over,she said that she would return to the area after finishing her studies.She now works as a math teacher at a high school in the city of Pingliang,Gansu province.

她说帮助别人改变了她的一生
在甘肃省一个贫穷的小山村教中学生对你来说听来可能没什么乐趣.但是,它改变了来自北京杨蕾的生活.这位北京大学毕业生第一次去那儿是以一名志愿者的身份参加一个为期一年援助计划.这项活动是由教育部和中国少年先锋队发起的.每年他们派100位志愿者到中国偏远地区去支教.
山区的生活对杨蕾来说是一次新的经历.她所在的村庄海拔2000米,起初稀薄的空气让她觉得很恶心.食物非常简单,---- 教师们一日三餐喝都粥.幸运的是,杨蕾的母亲赞同她女儿的决定（支持她）.她说她和她的丈夫都认为那是一个好主意.她说,“如今的年轻人需要经历不同的事情.”
大多数小学生住在学校宿舍里.他们学习很刻苦.他们早晨5点起床一直学到晚上11点.他们喜欢有志愿者教师到那里.“你和他们之间没什么区别,” 杨蕾说.“他们说我们像他们的大哥哥和大姐姐,并且他们感到很幸运.”
其中的一些学生可能没有能力上高中或者大学.家庭贫困,往往也没有钱交学费.“我对此感到无能为力.”杨蕾说,“但是我能把学生的视野拓展到外面的世界,并且给他们的生活（创造）一个良好的开端.” 她说她喜欢在孩子们的生命中留下一个好的影响.
杨蕾非常喜欢她作为志愿者的时光.当她为期一年的支教生活结束时,她说在她完成她的学业之后,她将返回该地区.她现在在甘肃平梁市的一所高中里当一名数学教师.
