These days, more and more people are always looking at their phones with their heads down. Such people are called “Heads-down Tribe(低头族）”. 【小题1】 (member) of the heads-down tribe can be seen everywhere. They spend most of their free time 【小题2】 (use) their phones. As a result, they lose many nice other things in life. For example, they spend   【小题3】 (little) time on face-to-face communication than before.

Also, they sometimes put 【小题4】 (they) into great danger. One day, it was raining 【小题5】 / 'hev1li/. A man with 【小题6】 umbrella was walking on the side of the road and playing his phone. He was so interested in the phone 【小题7】 he didn’t notice a big tree in front of him. As a result, he knocked hard into the tree and fell down on the wet 【小题8】 /ɡraʊnd/. The phone, together with his right arm, was 【小题9】 /ˈbrəʊkən/.

Mobile phones are useful and necessary in modern life. Whether (是否) they are good or not depends 【小题10】 how people use them. Let’s be healthy users and try to be the “Heads-up Tribe”.

ChatGPT is a chatbot. OpenAI created it. Earlier this year, the company’s website became one of the world’s fifty most-visited. When people ask a question online, they will get 【小题1】 answer to it from the chatbot. The answer reads like an essay (文章).

A growing number of educators say it’s too late to keep AI out of their classrooms. In a recent survey, 73% of 【小题2】 (teacher) said they heard of ChatGPT, and 33% used it to come up with 【小题3】 (create) ideas for classes. 【小题4】 Washington, students used the program to help with their math. In London, a teacher used ChatGPT to simplify texts for students, 【小题5】 their English is not good enough.

ChatGPT doesn’t always get things right. But teachers say this can give a way to make students become more 【小题6】 (interest) in study. The program created some essays. Some teachers ask students 【小题7】 (check) those essays. Sarah Millard, a teacher in Rochester, had students critique (评论) a ChatGPT essay on Shakespeare’s Romeo and Juliet. She said students 【小题8】 (enjoy) it a lot.

Some educators say it would be unfair to other students if teachers let some students use AI to do 【小题9】 (them) schoolwork. It’s not clear how much AI will change schooling. One thing is 【小题10】 (certainly): There’s no substitute (替代) for human connection. One teacher says, “I high-fived my students. I cried with my students. A computer will never do that.”

The first robots were invented in the 1920s. Now robots often 【小题1】 (appear) in many American films. In some films, they are stronger, faster and 【小题2】 (clever) than people. In real life, the robot is a very important 【小题3】 (invent) can do some dangerous and difficult jobs for humans.

Robots also help disabled people. Many blind people take a guide dog 【小题4】 (go) out. In the future, guide dogs may be robot dogs. One kind of robot guide dog has 【小题5】 (wheel). The owner wears a special belt (腰带). This belt sends instructions 【小题6】 the owner, such as “Stop here.” or “Turn right.” It helps blind people walk 【小题7】 (safe).

In the United States, disabled people use a kind of robot to take care of 【小题8】 (them) in their daily life. The robot hears the sound of its owner’s voice. It follows instructions such as “Turn the page.” or “Make a cup of coffee.”

Robots are also used in hospitals. A robot takes meals from the kitchen to patient’s rooms. It never gets lost because 【小题9】 robot has a map of the hospital in its memory. 【小题10】 robots can help people do everything, will we have nothing to do one day?
