    Jia Meng used to keep a diary in Chinese. But one year ago, the 14-year-old girl from Heilongjiang began to keep her diary in English, 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 (隐私)becomes safe and my English improves a lot.

    Jia's mother is not the only mom who reads her child's diary. Recently, Renmin University of China had a national survey among over 23,000 parents. The results show that 40% of the 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 it on paper. He writes online, 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, Liu asked her parents to buy her a mobile phone.

    “Parents want to know what is going on in their children's lives,” 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, talking to parents is a better solution. If your parents know that you are safe, they'll let you keep your secrets.

Many years ago, when I was working as a volunteer(志愿者)at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion(输血)from her five-year-old brother. The little boy had the same disease before and had developed the antibodies(抗体)to fight the illness.

    The doctor talked to me little boy about what they planned to do, and asked him if he would be willing(愿意的)to give his blood to his sister. I saw him hesitate(迟疑)for a moment. He took a deep breath and said, "Yes, I'll do it if it can save Lisa."

    As the transfusion was going on, the little boy lay quietly in bed next to his sister. He looked at her and smiled all the time. When everything was done and the color returned to his sister's face, his smile disappeared and he looked a little afraid. He looked up at the doctor and asked, "Will I start to die now?"

    He was too young to understand the doctor. He thought he would have to give all his blood to his sister, but he agreed.

Leonardo da Vinci was a famous artist who was born in Italy. He was also a great inventor. Many of his inventions have become important in modern life.

Besides, Leonardo spent days thinking about how to save time. He developed ideas for something like cutting machines.

Leonardo was a strange man. He never ate meat. That was very unusual in those times. He never published(发表) discoveries about science. He usually used mirror writing, which looks like usual writing in a mirror, starting from the right side of the page and moving to the left side。

Only a few of his paintings are left today. Many paintings were not finished because he thought they were not perfect.

Leonardo was talented and creative. He was regarded as one of the most intelligent men in the world.
