How does AI do this? First, workers take clear digital pictures of the old pages. Then, the AI system studies these pictures carefully. It looks at the words around the empty spaces and guesses what the missing words might be. This helps to complete the book digitally without touching the original one, which could be easily damaged.

Once a book is digitally repaired, it can be transformed into an e-book or added to an online database.    ▲   . For example, a student living in a small village can now read a special old book online. Before, he might have to travel to a big city library to see it.

AI can also help organize these digital books. It can sort them by their topics, time, or writers. This makes it much easier for students and teachers to find the information they need quickly.

Using AI to save old books is a new and good way to protect our history. It serves as a powerful bridge connecting the past with the future, ensuring that the wisdom and stories contained in these old books will not be forgotten and will continue to teach people in the future.

One year, as Father's Day was coming up, David's wife and kids wanted to do something2 for him. They knew he worked hard and hardly took3 , so they decided to plan a surprise weekend holiday to a nearby lake.

They prepared everything they needed for the4 , including David's favourite snacks and games. As they drove to the lake, David had no idea what his family had planned for him. When they got to the lake, a lovely house with trees all around it5 them. David was so surprised!

From then on, David started to spend more time with his family. He left work early, had dinner with his family and9 his kids. He even spared time to attend his kids' school events.

Susan Cain was a shy girl. She always had a hard time talking with new people. But when she grew up, she became a reporter(记者).  But Susan thought that her shyness made her a better reporter. "Being shy makes me more believable -- people feel more comfortable around me," she said.

Some people are not shy when they are with their friends.  So why are some people shy?

Scientists once did a study on two - month - old babies. They found that of every five babies, one was very active(活跃的).  And one of every five babies was always quiet. These babies might be shy when they grew up.

Family also affects(影响)shyness.  Studies show that children who are shy usually have parents that have fewer friends and fewer family activities.

People who are outgoing are sometimes more successful. Shy people may feel that they have a disadvantage(缺点). But shyness can be an advantage.  They are good friends because they listen more than they talk. This can also make them successful.
