How do you study each day? You may answer it in one second: have classes at school, take notes and do homework. There are some normal ways. Do they seem a little boring? If so, there are other new ways that can make learning interesting. It’s digital(数字化) learning.

There are three important kinds of digital learning. The first kind is apps(应用). People can download them on their mobile devices(设备). For example, the app Khan Academy(可汗学院) covers many courses such as math, physics, computer science and so on. The other two kinds are social networking services such as weibo and WeChat and websites. Each of them is like your teacher. They help you learn more.

Compared with normal learning ways, digital learning has its good sides. It almost covers everything. More importantly, it’s always updating(更新), which offers students the newest things to learn from. Digital learning can meet different learners’ needs. You can choose   what   you   like   to   earn.   You   can   also   learn   at   your   own   speed.   If   you   don’t understand what you have learned at school, you can learn again whenever and wherever you want to.

However, digital learning also has downsides. When you use digital ways to learn, there is little connection with teachers and classmates. As digital learning uses computers or smartphones, watching the screen too long may be bad for your eyes. It is better to take a rest every 20 minutes.

文章大意:本文主要讲述了聊天机器人ChatGPT的迅速流行以及人们不同的看法。
【推荐2】阅读下面短文,根据其内容填空和回答问题。(14题每题答案不超过3个单词,5题须用完整句子回答)

ChatGPT, an AI chatbot tool (聊天工具), has quickly become popular since it came out in late 2022. It can do a lot of things such as chatting, doing translations and even writing codes for a computer program. While it has surprised the world, it has also caused both excitement and worries in teaching and learning.

According to a survey covering over 1, 000 students and 100 educators, about 89% students said they used it to help with homework. About 48% said they used it to finish home tests. And over 50% used it to write an article. 34% of the educators said ChatGPT should not be banned (禁止) in schools and universities. But 66% thought students could not use it.

Now, some universities and schools in New York City have already banned the use of ChatGPT. They are really afraid that the tool could make it easier for students to cheat (欺骗) and be used to spread wrong information. Besides, they think the tool does not build creative-thinking and problem-solving skills, which are important for lifelong success.

However, some people think banning ChatGPT is not smart. Instead of simply banning it, using it can free teachers and students from the simple work so that they can do more creative work. To avoid (避免) cheating, instructions on how to use it in a right way should be given.

1. ChatGPT is a ____________ AI chatbot tool today.
2. According to the survey, over half of students use ChatGPT to __________________.
3. In New York, some ________________ have stopped students from using ChatGPT.
4. From paragraph 3 and 4, we know people have ___________ about stopping using ChatGPT.
5. Do you want to use ChatGPT in your life? Why or why not?
