We are now living in the 21st century. Is your classroom living in the 21st century, too? Tony is a student in Grade 8 at an American middle school. He was surprised when he saw his m1. classroom on his first day of school.
In Tony’s classroom, there are many new electronics like iPads. This term, they will use the electronics to take notes, watch videos and do p2. and homework. "It’s amazing!"said Tony. "I p3. using an iPad to work on math or other projects with my team members."
The school uses new technology in classrooms to help students see, hear, t4. and sometimes experience their tasks. “Technology is pretty c5. in most of our classrooms now," the head teacher said. "We are trying to use technology to open up the world to kids. It can b6. the outside world in."
Science teacher Mr Miller agrees. "It is a quick w7. for students to know the outside world," he said. Mr Miller now c8. himself as a guide of learning not as a teacher. "If they have a question for me, I will try to teach them how to find the answers rather than tell them what the answers are," he said.
Dale, another student, loves technology. He was not really interested in class before, b9. now he likes the classes very much. "It helps me use w10. I know about technology at school," Dale said. "Most importantly, I enjoy the classroom. This, of course, will help my studies."
Artificial intelligence（人工智能）, or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies. AI is rapidly catching up with the human ability to read faces. As a result, facial recognition（面部识别）is used a lot in the world. Chinese police use this technology to identify criminals（罪犯）.Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing（网约车）drivers and lets people pay for things with a smile.
AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don't have this ability. Carmakers are testing a light signal system to help them "speak" to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding（让路）, it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.
Service Robots also show you how powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers. AI is so powerful that it can help human beings and even replace us in many jobs.
