In 1909. when Tatiana was just 11 years old, her parents and older brother traveled to the United States. Because the family didn’t have enough money to buy her a ticket, she had to remain in Russia.

She had lived with her uncle for almost a year in a small house before the special letter arrived from her father. “Dear Tatiana,” he wrote.” At last we have earned enough money to pay for your ticket. After you join us in New York, we will travel by train to a place called South Dakota where we have bought a farm.”

A week later, Tatiana’s uncle used the the money her father had sent to buy her a ticket for the Louisa Jane, a steamship that was leaving for America. Although she was lonely and missed her family, Tatiana quickly made friends with the other children on the Louisa Jane. Together, they invented games that could be played on the ship , and they ran around the decks(甲板).

The next day, as Tatiana was walking along the deck, she heard some of the passengers talking about the Statue of Liberty. This conversation made her puzzled because she knew that liberty was an idea. No one could see or touch it, so how could you make a statue of liberty? When she asked her friend’s father, Mr. Dimitrivitch, he explained that the statue looked like a woman, but it stood for freedom. This explanation just made Tatiana more interested in the statue.

One morning , Tatiana woke up to the sound of wild shouting. She ran upstairs and found all the passengers were crowded onto the deck. The shouts were really cries of excitement because the Louisa, lane had finally reached the United States. When Tatiana realized that she would soon see her family again, she joined in with shouts of her own. Mr. Dimitrivitch had told her that the statue stood for freedom, and she finally understood what he meant.

What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.

I think AI (人工智能) will be more useful in our future lives. It’s now used in many : fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I’m sure AI will help us solve many problems.

—Tina

I am worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced (取代) because AI robots will do lots of human jobs.

—Bill

I really think that AI will change the way we work, the way we live, and the way we think. Imagine if we could put a CPU (中央处理器) into our brains! Soon we’ll be able to improve our math and memory. How exciting!

—Mary

Think of what’s happening right now: Some robots are used to kill animals under human orders. So I think AI will be very dangerous for humans. We need to be careful about what we ask machines to do.

Would you like to live in a city where buildings turn the lights off for you, and self-driving cars will find the nearest parking space themselves? Although it might sound a lttle far from you, living in a "smart" city like this could happen sooner than you think.

Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence system(远程遥控系统)-- allowing users to control the heating and locks, take part in video meetings, and receive education, health care and government services. Around the city, escalators ( 自动扶梯 ) will only move when someone is on them, and offices and schools will all be connected to the system.

The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.

About 75% of the world's population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. Making cities smarter is one way out, and I think this will in turn make cities greener, said Dan Hill, head of a research company.
