Have your ever heard of the world’s first 3D-printed village? A group called New Story is working with a company called Icon to quickly build lots of houses for poor people who need 【小题1】.The way they build the houses is unusual-it is 3D-printing technology.

Icon created the first 3D-printed house in the United States several years ago. New Story is a group that works to bring cheap but good houses to the poor. The group has 【小题2】 over 2,700 houses in places like Bolivia, El Salvador, Haiti and Mexico.

Icon and New Story have shown two new 3D-printed houses in Mexico. The two small homes are the 【小题3】 in a planned village of 50 3D-printed houses for very poor people in the area.

The houses in Tabasco have two bedrooms, a 【小题4】 room, a kitchen, and a bathroom. Because the houses are created with a computer design, it’s easy to change the design to suit the 【小题5】 of different families. Their printer is a machine called Vulean II. It works 【小题6】. The 46-square-meter homes were built in about 24 hours. New Story and Icon believe that with practice they will learn to make the houses even more quickly, and bring the price of 【小题7】 them down even further-perhaps as low as $3.500.

If time could be traded, whose time do you want to buy? Recently a Chinese company 【小题1】 an app called Miao A to help people "see who they want to see". More than 500 famous persons are on the app, including TV host He Jiong and musician Zuoxiao Zuzhou. There are also actors, businessmen and even video game players 【小题2】 their time to others on Miao A.

If you buy one second of time from a well-known person, you 【小题3】 a chance of one line in a text to chat with him or her. For a voice or video call, you must pay for at least 600 seconds. Those who hope 【小题4】 his or her favorite star in person must buy at least 7,200 seconds.

The Miao A app has been enjoyed by more than 100 thousand customers since it came out in June, 2017. However, there are some people who disagree with the idea, saying that "time" is not a product that can 【小题5】.

ChatGPT is an AI system (系统) that can have a discussion and create written work. It can create material based on what it has learned 【小题1】 digital books and online passages. Now three high school students in Cyprus have developed an 【小题2】 robot with the help of their teachers. It is special as it uses ChatGPT AI technology.

The robot is named AInstein. It is the size of a small adult and even has a screen for a face that appears to show human facial (面部) 【小题3】. It speaks a North American form of English. And it can 【小题4】, like “Why was the math book sad? Because it had too many problems.” The robot enjoys 【小题5】 science books and spending time playing the violin.

The creators of AInstein want to use the technology to 【小题6】 learning experiences in the classroom. In fact, there 【小题7】 be a place for robots in education after all. British education expert Anthony Seldon predicts that robots will take over the classroom in 2027 and teachers will work as their helpers.

One thing is certain, though. A robot teacher is 【小题8】 than no teacher at all. In some parts of the world, there aren’t 【小题9】 teachers and 9-16 percent of children under the age of 14 don’t go to school. That problem could be partly 【小题10】 by robots, because they can teach anywhere and won’t get stressed, or tired, or move somewhere for an easier, higher-paid job.
