Ⅲ.阅读理解(共4小题；每小题2.5分，满分10分) Google researchers have developed an AI tool，called MusicLM，which is designed to create music based on a set of descriptive words.While it is not the first AI music tool to launch，MusicLM demonstrates remarkable creative ability in generating music from limited inputs.To use the system，users enter words that describe the type of music they want to create，such as “a continuous calming violin backed by a soft guitar sound”．These descriptions can include different music styles，instruments，or existing sounds.The more detailed the description，the better the system can attempt to produce the desired music. MusicLM has generated several examples of music based on one­ or two­word descriptions such as “jazz” or “techno”．The system can also create music from more detailed descriptions containing whole sentences.The resulting music closely matches the input description.According to the team，the system can also generate music based on a person’s own singing，whistling，or playing an instrument.It produces high­quality music that can last several minutes while being staunch to the written descriptions. Although the MusicLM system is not yet available to the public，Google has released a dataset(数据集) of more than 5,500 music­writing pairs，prepared by professional musicians called MusicCaps.This dataset can help advance the progress of other AI music generators. The MusicLM system is an exciting development in the field of AI­generated music.It has the potential to help users quickly and easily create high­quality music.However，the team also acknowledges that machine learning has some risks associated with it.Just like any emerging technology，it is vital to thoughtfully examine and resolve any ethical issues that may surface. In conclusion，MusicLM is a promising tool that can generate high­quality music based on limited inputs.Its ability to create music from descriptions，singing，whistling，or playing an instrument is impressive.While its potential is exciting，it is crucial to address any ethical concerns that may arise from using this new technology. 语篇解读　本文是一篇说明文。文章介绍了谷歌研发出一款叫作MusicLM的人工智能工具，它可以基于书面描述等内容创作音乐。 1．How does MusicLM work?

But EveR 6 doesn’t think on its own like some advanced artificial intelligence programs.Instead，it has a limited group of movements that it has been trained to perform.To make these movements as natural as possible，EveR 6’s movements are based on those captured from real human conductors. In Friday’s performance，the National Orchestra of South Korea presented a concert titled “Absence”．The concert included five different pieces of music.Two were conducted by EveR 6，and two were conducted by Choi Soo­yeoul，who leads the Busan Philharmonic Orchestra.Both conductors worked together on the final piece. Mr Choi was impressed with the way EveR 6 moved.“The robot was able to present such detailed moves much better than I had imagined，” he said. But Mr Choi added that the robot’s biggest weakness is that it can’t hear.“Some people think that conducting is just a combination of hand waving and keeping the beat，” said Mr Choi.“But a good conductor needs to listen to the orchestra，so that he or she can correct and encourage the orchestra as it plays.” Mr Choi and EveR 6 both conducted a piece of music called “Sense”．Instead of musical notes，EveR 6 had instructions for how to play the piece.The conductors and musicians had to work together to create the music.Mr Choi communicated with the musicians while EveR 6 kept the beat.Mr Choi said that once EveR 6 started，the musicians had “no choice but to follow its beats”． Mr Choi doesn’t think robots are likely to replace human conductors.But he believes robots could be helpful in situations like practice sessions where the same thing needs to be repeated many times. 语篇解读　本文是一篇说明文。文章主要介绍的是由机器人EveR 6参与指挥的一场音乐会的情况以及韩国指挥家崔秀烈对EveR 6的评价。 1．What do we know about EveR 6 from the text? A．It is an experienced conductor. B．It has a lifelike appearance. C．It is able to listen to music. D．It is much shorter than a person. 答案　B 解析　细节理解题。根据第一段中的“EveR 6 is about as tall as a person，and has a human­like face that can show emotions.”可知，EveR 6有着类似人类的生动的外观。故选B。 2．What does the underlined word “captured”in paragraph 2 mean? A．Stolen. B．Stopped. C．Recorded. D．Hidden. 答案　C 解析　词义猜测题。根据画线词上文“it has a limited group of movements...To make these movements as natural as possible，EveR 6’s movements are based on those”及画线词后“from real human conductors”可知，为了使这些动作尽可能自然，EveR 6的动作是基于从人类指挥家那里记录到的动作。由此可知，画线词的意思是“记录”。故选C。 3．What advantage does a human conductor have over EveR 6? A．Waving hands. B．Keeping the beat. C．Having instructions. D．Communicating with musicians. 答案　D 解析　细节理解题。根据第五段中的“‘But a good conductor needs to listen to the orchestra，so that he or she can correct and encourage the orchestra as it plays.”及第六段中的“Mr Choi communicated with the musicians while EveR 6 kept the beat.Mr Choi said that once EveR 6 started，the musicians had ‘no choice but to follow its beats’．”可知，与EveR 6相比，人类指挥的优势是会和音乐家交流，故选D。 4．What is the text mainly about? A．A robot conducting an orchestra. B．An orchestra having performed in South Korea. C．Modern music combined with technology. D．Two conductors getting worldwide recognition. 答案　A 解析　主旨大意题。根据第一段中的“Last Friday，a robot called EveR 6 led an orchestra(管弦乐队) in a performance of Korean music at the National Theater of Korea.”并结合下文可知，本文主要介绍了一个指挥管弦乐队的机器人。故选A。 B Recently，Google researchers published a paper describing results from an artificial intelligence(AI) tool，called MusicLM，built to create music.It is not the first AI music tool to launch.But the examples Google provides demonstrate musical creative ability based on a limited set of descriptive words.AI shows how complex(复杂的) computer systems have been trained to behave in human­like ways.Google engineers explain the MusicLM system this way： First，a user comes up with a word or words that describe the kind of music they want the tool to create.For example，a user could enter this short phrase into the system: “a continuous calming violin backed by a soft guitar sound”．The descriptions entered can include different music styles，instruments or other existing sounds.Several different music examples produced by MusicLM were published online.Some of the generated music came from just one­or­two­word descriptions，such as “jazz”，or “techno”．The system created other examples from more detailed descriptions containing whole sentences.In the resulting recording，the music seems to keep very close to the description.The team said that the more detailed the description is，the better the system can attempt to produce it. In addition to generating new music from written descriptions，the team said the system can also create examples based on a person’s own singing，whistling or playing an instrument.The researchers said the tool “produces high­quality music...over several minutes，while being faithful to the text conditioning signal”． Although MusicLM hasn’t been released for public use，Google announced it was releasing a “high­quality dataset” of more than 5,500 music­writing pairs prepared by professional musicians called MusicCaps.The researchers took that step to assist in the development of other AI music generators. The MusicLM researchers said they believe they have designed a new tool to help anyone quickly and easily create high­quality music selections.However，the team said it also recognizes some risks linked to the machine learning process. 语篇解读　本文是一篇说明文，主要介绍了谷歌开发的名为MusicLM的人工智能工具，该工具可以根据书面描述创作音乐。 5．Which instruction may help create the most accurate music by MusicLM? A．Rock and roll. B．A piano piece to uplift one’s spirits. C．Eastern music. D．A mixed sound of guitar and violin. 答案　B 解析　推理判断题。根据第二段最后一句“The team said that the more detailed the description is，the better the system can attempt to produce it.”可知，描述越详细，系统越能更好地尝试生成音乐，结合选项可推知，B项(一首振奋精神的钢琴曲)描述得最详细。故选B。 6．Why did Google release the MusicCaps dataset? A．To allow the public to use MusicLM. B．To display the capabilities of MusicLM. C．To help develop other AI music generators. D．To promote the MusicCaps music­writing service. 答案　C 解析　细节理解题。根据倒数第二段中“Google announced it was releasing a ‘high­quality dataset’...The researchers took that step to assist in the development of other AI music generators”可知，谷歌发布MusicCaps数据集是为了帮助开发其他AI音乐生成器。故选C。 7．What will be probably talked about following the last paragraph? A．Problems about the new tool. B．Advantages of using MusicLM. C．Background of the research team. D．Application of AI technology. 答案　A 解析　推理判断题。根据最后一段最后一句“However，the team said it also recognizes some risks linked to the machine learning process.”可知，最后一段提到了与机器学习过程相关的一些风险，所以可推知，接下来应该是讨论具体的风险有哪些。故选A。 8．What is the main idea of the passage? A．MusicCaps behaves in human­like ways. B．AI makes music accessible to ordinary people. C．Musicians recognize the true value of MusicLM. D．MusicLM creates music from written descriptions. 答案　D 解析　主旨大意题。通读全文，尤其根据第一段第一句、第三句以及第二段内容可知，本文主要讲述了MusicLM可以根据书面描述创作音乐。故选D。 Ⅱ.完形填空 (共10小题；每小题1.5分，满分15分) Joy took Teresa’s hand in its mouth and led her to the living room.Her son，Dominic,20，lay in a chair with his eyes closed and 1 for breath.Thanks to the dog，the boy was saved again before it was too 2 .
