            ¡¡¡¡Kungsang Dekyi is an ordinary teenager who lived a quiet life in Yushu, Qinghai. However, ¢Ù the April 14 earthquake made her famous overnight.
            ¡¡¡¡When her house collapsed (µ¹Ëú) with her family still inside, the 16-year-old Tibetan girl dug for a whole day using only her hands. In the end, she was able to save all nine members of her family.
            ¡¡¡¡On the morning when the earthquake took place, Kungsang Dekyi was on her way to get a photocopy (¸´Ó¡¼þ) of her ID card. Suddenly she saw the ground shaking and houses breaking down. She ran back home to find her house buried (Âñ) by rocks. With tears on her face, she began removing the heavy rocks and digging over ruins with her hands. Although all her fingers were covered in blood, she did not stop. Two hours later, she found her mother. She first pulled her mother out. ¢ÚAfter 12 hours of digging, she saved all nine of her family members.
            ¡¡¡¡Kungsang Dekyi¡¯s story quickly spread around the quake areas and the whole country, making her a heroine in many people¡¯s eyes. Now she and her family are living in a makeshift house (°å·¿). ¡°But just being alive is good,¡± she says. As a student in a local vocational (PLCÅàѵµÄ) school, ¢Ûshe hopes to become a nurse or a doctor one day so that she can help as many as people as possible.

            ¡¡¡¡How many text messages do you send each day? According to a survey of the Pew Research Center in the US, a third of US teenagers send more than 100 text messages a day. Short Messaging Service (¶Ì) is now more popular than face-to-face conversations, telephone calls and even social networking sites (ÉçÍøÕ¾) such as Facebook.
            ¡¡¡¡The Pew Research Center said teens prefer text-messaging to communicating with friends no matter where they are, even under the noses or parents or teachers. It seems that some teens are addicted (ÉÏñ«) to texting. This could have a bad influence on our lives, from study to health.
            ¡¡¡¡Annie Levitz, a 16-year-old girl from Lincolnshire, Illinois lost feeling in her hands after sending over 100 texts a day from her mobile phone. She will have to have surgery (Íâ¿ÆÊÖÊõ) on her wrists (ÊÖÍó) in order to deal with the problem.
