    Nadia Comaneci, a famous gymnast(体操运动员), was born in Romania in 1961.

    When she was doing cartwheels (侧手翻) on the playground at the age of 7, a PE teacher saw her. He told her family that she was very good and advised Nadia to train in the capital of Romania. Although it was a long way from her home, Nadia went because she loved gymnastics(体操).

    After that, she trained hard and took part in lots of competitions. In 1975, she was named as one of the Athletes of the 20th Century.

    In 1976, Nadia went to the Olympics in Canada. She was so fantastic in the competition that everyone waited for the score, a high score. But the score board showed 1.00!

    Everyone was surprised. There wasn't a sound for a moment. Then a voice came. "Ladies and gentlemen, Nadia Comaneci…10!"

    The audience cheered very loudly. So what happened? Well, when the scoreboard was built, no one thought a score of 10.00 was possible. The decimal point(小数点) was in the wrong place! In fact, the scoreboard only had three digits (数位) to show scores, such as 9.50 or 9.85 at that time.

    In the 1976 Summer Olympics, Nadia Comaneci scored a perfect 10, which was thought impossible before. From then on, she was looked as a hero. In 1984, she got retired (退休的).

Do you think there will be a robot in hospitals? If you go to a hospital in London, you'll see a new doctor there. He is very clever. He can work 24 houts a day and never gets tired. He is Dr Robot. 

Doctors often need to ask their patients a lot of questions, and it always takes them a lot of time to do that. But Dr Robot can ask patients questions for an hour if it is necessary. With the help of Dr Robot, a human doctor can have a lot of useful information when he meets his patients. 

How can Dr Robot do this? A computer "tells" him what to do. Dr Robot can do a lot of things that people can do, though he can't completely replace human doctors.
