But one year ago, the 14-year-old girl from Hei Longjiang began to write her diary in English, because Jia found her mother was reading her diary secretly. She changed the language because her mother cant read English. “Its like killing two birds with one stone.” said Jia, “My privacy (隐私) became safe and my English improves a lot.” Jias mother is not the only mom who reads her childs diary. Recently, Renmin University of China did a national survey among over 2, 3000 parents. The reports say that 40% of parents read their childrens secrets. Thats why, like Jia, many teenagers try to find ways to protect their privacy. Wu Lei, 15, of Shanxi, keeps a diary, too. But he doesnt write it on paper. He writes on the Internet which he thinks is perfectly safe because his parents “know nothing about the Internet.” Lu Huan, 13, of Guangdong, said her parents always secretly listened to the talk between her friends and her on the telephone in their room. To solve this problem, Lu asked her parents to buy her a mobile phone. “Parents want to know what is going on in their childrens lives,” said Shao Xiazhen, a teenage expert in Beijing. “ But sometimes they go about it the wrong way.” Shao gave teenagers the idea that instead of hiding their secrets, talking to parents is a better way. “If your parents know that you are safe, theyll let you keep your secrets.” Title: Finding 1 to protect privacy Phenomenon(现象) Its 2 that 40% of parents read childrens secrets.ExamplesJia Meng used to keep a diary in Chinese but now she has been used to that in the English 3 .Wu Lei thinks writing 4 instead of on paper is a safe way to stop parents from 5 his diary.Lu Huan asked her parents to buy her a mobile phone because her parents action 6 her talk with her friends.7 on protecting privacySince parents 8 what was happening in childrens lives, a teenage expert _9_ Shao Xiazhen advised that hiding the secrets should be less 10 than talking to parents.1_
