缺詞填空 (共10空;每空l分,計l0分)

根據短文內容和首字母提示,在下文空格處填入適當的詞使短文完整。(每空一詞)

Jia Meng used to keep a diary in Chinese. But one year a__1__, the 14-year-old girl from Hei Longjiang began to write her diary in E__2__, because Jia found her mother was reading her diary secretly. She changed the language because her mother can’t read English. “It’s like killing two birds with one stone.” said Jia, “My privacy (隱私) became safe and my English improves a lot.”

Jia’s mother is not the o__3__ mom who reads her child’s diary. Recently, Renmin University of China had a national survey among over 2, 3000 parents. The results s_4__that 40% of parents read their children’s secrets. That’s why, like Jia, many teenagers try to find ways to protect their privacy.

Wu Lei, 15, of Shanxi, keeps a diary, too. But he doesn’t write them on the paper. He writes o__5__ which he thinks is perfectly safe because his parents “know n__6__ about the Internet.”

Lu Huan, 13, of Guangdong, said her parents always secretly listened to the talk b__7__ her friends and her on the telephone in their room. To solve this p__8__, Lu asked her parents to buy her a mobile phone.

“Parents want to know what is going on in their children’s l__9__,” said Shao Xiazhen, a teenage expert in Beijing. “ But sometimes they go about it the wrong way.” Shao suggested to teenagers that instead of hiding their secrets, t__10__ to parents is a better solution. “If your parents know that you are safe, they’ll let you keep your secrets.”
