The UL robot isn’t 27 , and it costs about $125,000. It sounds expensive, but after the scientists compared it 28 other machines in the laboratory, they thought it was worth it. The fact that the robot can 29 do many different things is a huge good thing.

According to a survey, there is one autistic kid (自闭症儿童) in every 54 children. Autism influences the way children feel and hear, and how they see the world. They need much help in daily lives.
A special helper came to Mendip School, a school for autistic students in England, in late June, 2021. It’s a friendly robot called Pepper. Pepper joined the students between 12 and 19 years old at the school for three weeks.
Every time Pepper met students in the school’s hallway, the robot said hello and asked them how they felt. Pepper could do a lot of things like dancing and telling stories. “Because of Pepper, there was a lot of dancing in school. And children loved the robot’s jokes,” said a teacher called Conley. “Some children didn’t like to talk or play with others in the past. But now, it’s not so difficult for them to start up new friendships with others.”
Using robots to help autistic children is not new. However, most robots only teach skills to children. That’s not what autistic children really need. Pepper is different. It works to get autistic children happy.

Developed by US company OpenAI, ChatGPT has taken the Internet by storm, winning 100 million users since it came out in November 2022. People can ask the robot to write stories and emails, create instructions for cooking a certain food, translate languages, and answer all kinds of questions. In its own words, it is “a language model trained in a large amount of Internet text to help users get human-like text.”
Compared with Siri or other chatbots, ChatGPT uses a much bigger information center for training. It also uses stronger software (软件) and hardware to learn things by itself. For example, if it provides a wrong answer to your question, you can tell it the right one and it will correct itself. “It’s a totally different chatbot,” computer scientist Liu Xiaoguang from Nankai University told Tianjin Daily. “The knowledge level ChatGPT shows is the same as a university student. That’s why it shocked the world.”
But one big problem with ChatGPT is that it makes mistakes or even gives false information. When Rezza, a 28-year-old from Indonesia, used the robot to write an essay (论文), it “gave out many examples which other writers actually hadn’t mentioned at all”, he told The Guardian. Since the robot is trained using words from the Internet, It can also pick up biases (偏见) about certain groups. These are all things that need to be dealt with.
( )38. Which can replace the underlined part in Paragraph 1
A. Succeeded greatly online.
B. Done harm to the Internet.
C. Brought strong wind and heavy rain.
D. Caused serious changes of the weather.
( )39. Why did ChatGPT shock the world
A. It can find mistakes by itself.
B. It works differently from other chatbots.
C. Its information center is easier to control than Siri’s.
D. Its knowledge level is as high as a university student.
( )40. What can we learn from the last paragraph
A. Anybody can make mistakes.
B. Anybody may give false information.
C. ChatGPT needs improvement.
D. ChatGPT can’t get on well with humans.
( )41. What might be the best title of the text
A. ChatGPT Is Coming!
B. ChatGPT Is Catching the World’s Eyes!
C. Can ChatGPT Take the Place of Humans
D. Can ChatGPT Avoid Biases Properly

AI (人工智能) can help teenagers and students learn in several ways.
Personalized learning
AI can know better about students, including their advantages, weaknesses, skills, learning favorites, learning needs, and so on. Then it can create a proper learning plan for each student. This can help students concentrate on areas that they need to improve at their own speed.
Interactive (交互的) learning
AI has the ability to make learning more interactive and interesting. Things like interactive learning apps and educational games can make subject learning more interesting. What’s more, they can make students interested in a subject at once. This kind of active learning is sure to be more helpful than studying alone.
Automated (自动的) advice and help
AI can provide automated advice and answers to questions. It can examine students’ work and provide personalized help. For example, ChatGPT can answer students’ questions quickly in a private, low-pressure way. This kind of advice and answers can help students better understand knowledge and use their knowledge.
Greater resources
AI can make many of the students’ learning resources richer and wider, like electronic textbooks, online courses, and study apps. For example, a biology textbook with AI technology may provide interactive 3D models of a human body that students can study more carefully. AI can provide interactive examples, introduce important passages, and offer assessments (评价).
In a word, AI has a great ability to improve studying and learning. By using AI, students can study smarter and reach higher levels of learning and success. The future of AI in education is hopeful as technologies continue to develop.
( )42. What can AI do by knowing better about students

61. a 【解析】根据句意和句子结构可知, 这个空后的名词“machine”是单数, 且这里表示泛指。故填a。
62. patiently 【解析】根据句子结构可知, 空处应填副词来修饰动词“helps”, 故填patiently。
63. more active 【解析】根据句意及句中的“than”可知, 应用形容词的比较级。故填more active。
64. tools 【解析】“one of the...”表示“……之一”, 后面要跟可数名词的复数, 故填tools。
65. has introduced 【解析】根据句意和句中的时间状语“In the past few years”可知, 要用现在完成时；主语“the school”为单数, 故填has introduced。
66. It 【解析】根据“...is necessary to encourage kids to come up” 可知是固定句型：“It is+ 形容词+ to do sth.”, 意为“做某事是……的”, 其中“It”是形式主语, 真正的主语是动词不定式。故填It。
67. with 【解析】根据“come up...new ways”可知考查固定短语come up with, 意思是“想出, 提出”。故填with。
68. added 【解析】根据文意可知, 对校长的采访是已经发生过的事情了, 所以应用一般过去时。故填added。
69. to help 【解析】根据“are used”可知此处考查短语“be used to do sth.”, 意为“被用来做某事”, 指的是机器人老师被用来帮助提高学习。故填to help。
70. but 【解析】根据空前的“teach well”和空后的“they are not able to keep class in order”可知前后是转折关系。故填but。
六、范文：
Dear Sir / Madam,
Order number 8043197725
Thanks for your attention. I’m writing to complain about your product.
Two weeks ago, I ordered a mobile phone from your online shop. However, the quality of this mobile phone is not up to standard.
First of all, its battery can last for half a day at most. I think it should last at least a whole day. Also, there is something wrong with its screen. From time to time, I can’t see what is on the screen.
I’m not satisfied with this mobile phone at all. I regret buying a mobile phone like this. I would like to get my money back.
I’m looking forward to your early reply.
Yours sincerely,
Li Hua
作文点评：本文采用“三步法”写投诉信——投诉的对象、产品问题及写信目的。本文作者在投诉信的开头就直接指出了自己投诉的对象, 然后说明了自己购买的手机出现的问题, 以及自己对处理这个问题的要求。作者在题中所给信息的基础上展开合理想象, 整篇文章明快、流畅, 层次清晰；在语言表达上, 作者用not up to standard, be not satisfied with, not ... at all 等表达了对此手机的强烈不满, 同时也显示出作者扎实的英语语言功底。
添彩点：文中画线词句是文章的出彩之处。
