AI, or artificial intelligence (人工智能), is everywhere today! From smartphones to smart homes, AI makes our lives easier. But what exactly is AI Think of it as a super-smart computer that can learn, solve problems, and even understand human languages. Now, let’s explore how AI helps us.
AI is like a helpful assistant in daily life. For example, voice assistants like Siri or Alexa can answer questions, set alarms, or control your home lights. They use “natural language processing” to understand what you say. In schools, AI tools help teachers grade homework faster and suggest personalized learning plans. Some apps even correct your spelling and grammar in real time!
AI also plays a big role in healthcare and education. In hospitals, AI can analyze X-rays and help doctors find diseases early. It’s also used to develop new medicines. Meanwhile, in education, AI-powered apps like Duolingo teach languages by fitting in with your learning speed. Imagine having a 24/7 tutor (家庭教师) who knows exactly what you need!
Although AI can do many things, it’s not perfect. Some people worry that it might take all jobs, like factory work or customer service. However, experts say AI will also create new jobs, like robot repair and AI programming. The key is to use AI wisely. For example, self-driving cars use AI to reduce accidents, but humans still need to monitor them.
Remember, AI is a tool—it doesn’t replace humans, but it can make our work smarter. So let’s accept AI with curiosity! By learning to use it responsibly, we can build a better future together.
21．What does the underlined word “They” refer to
A．Voice assistants. B．Home lights. C．Learning plans. D．Some apps.
22．Which of the following can summarize Paragraph Four
A．AI will replace all human jobs. B．AI is helpful in healthcare and education.
C．AI is helpful but not perfect and needs wise use. D．AI can build a better future for humans.
23．What’s the structure of the passage (P1: Paragraph 1; P2: Paragraph 2...)
A． B． C． D．
24．Where can we read the passage
A．In an education newspaper. B．In an entertainment poster.
C．In a self-driving car ad. D．In a science magazine.
25．What’s the best title for the passage
A．AI: a powerful tool for our lives B．How to make an AI software
C．A tool which may replace humans D．The development history of AI

My Digital Life
Digital tools play an important role in my life. I usually study online, watch educational videos, and chat with friends through social media. These activities make my life more convenient and efficient. For example, I can access global knowledge instantly. However, overusing devices may cause eye strain or privacy risks.
