八年级下册英语第四单元最后面的Section While You Read的《She said helping others changed her life》
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 2,000 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.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 5am and read books until 11pm.They love having the volunteer teachers there.“There is no difference between you and them,” says yang Lei.“They say that we are like big __brothers_ or sisters to them,and they feel lucky.”
Some of the students 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,” says Yang lei,“but I can open up my students’ eyes to the outside world and give them a good start in life.” She said she likes being a good influence in the children’s lives.
Yang Lei enjoyed her time 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.以上就是这篇了,把它的中心概括出来,不要超过100个单词.（急）
