In their 5______, the scientists invited 244 volunteers to play an online ball game with an AI bot.

The phoenix coronet is one of the museum’s most famous exhibits(展览品).It is decorated with nine phoenixes, nine dragons and thousands of pearls. It was made with wonderful craftsmanship during the Ming Dynasty. Because of its great value, this treasure has never been shown abroad. Over 80,000 such magnets have been sold within just three months, bringing in over 10million yuan, said a worker from the museum. It’s common to see some people carrying bags full of the fridge magnets in the museum. According to the gift shop workers, the magnets are not exclusive(独有的) to the museum, as you can also buy these magnets online. Across China, museums have introduced cultural and creative products designed after their collections. As these products become more popular, they help people learn more about the museums and interesting historical facts. However, workers of the museums hope that visitors can focus more on the museums themselves and their rich culture, rather than just buying magnets and taking photos. 1.Where did the idea for the magnet’s design come from? ________________________________________________________________ 2. Why hasn’t the phoenix coronet been shown abroad? ________________________________________________________________ 3. Besides the museums, where can people buy the magnet? ________________________________________________________________ 4.
