They have improved facial expressions and human-like voices—an upgrade from other AI systems’ robotic sounds.”可知,Expressive Avatars拥有改进的面部表情和人类般的声音,所以它们的特别之处在于它们更加逼真,更像人类。故选B。 2.A　细节理解题。根据第三段中的“Riparbelli explained that the company hired thousands of actors to record videos for the model to ensure exactness.”可知,Synthesia使用真实演员的视频来训练其Express-1 AI模型。故选A。 3.C　推理判断题。根据第五段中Synthesia的公告“We’ve taken additional steps to prevent the misuse of our technology, including updating our policies to limit the type of content people can make, working on the early finding of dishonest actors, and increasing the teams that work on AI safety…”可推知,第五段提到Synthesia的公告是为了展示其应对技术风险的努力。故选C。 4.A　推理判断题。根据全文内容,尤其是由第一段中的“These avatars are part of what Synthesia calls its ‘digital actors’. They have improved facial expressions and human-like voices—an upgrade from other AI systems’ robotic sounds.”和第五段内容可知,作者既介绍了Expressive Avatars技术的优势,也提到了其潜在的滥用风险,并客观地陈述了公司为防止滥用所采取的措施。因此,作者的态度是客观的。故选A。 B 【文章大意】 本文是一篇说明文。文章主要讲述了人类与动物沟通的可能性及AI在动物语言翻译上的作用。 5.B　推理判断题。由文章第一段中“Do you ever look at your dog, or cat, or a bird flying by the window and wonder, ‘What on earth are you thinking?’”可知,作者询问读者是否曾经好奇过动物的想法,因此作者的主要目的是表达对动物想法的好奇。故选B。 6.D　推理判断题。由文章第四段“Animals communicate by a wide variety of different means. Most of this communication is message passing between the same species, but between-species communication is also rich. Think of an insect or fish changing colour to warn off attackers or remind them of their toxicity (毒性). But can these happen between humans and other animals?”可知,作者提到鱼变色是为了展示不同物种间的交流示例。故选D。 7.C　段落大意题。由文章第五段“Any dog owner knows that if you shout at a dog for some wrongdoing, the dog knows it is being told off and answers accordingly. But there is a danger in thinking that animals can fully understand human communication. We human beings have our own awareness and specific human experience. The rest of the animal kingdom experiences the world in a way quite different from ours. So, even if we could understand what their calls mean, would we be able to catch what they are trying to say?”可知,本段主要讨论的是人类是否能够理解动物的问题,即对人类能否理解动物的怀疑。故选C。 8.A　推理判断题。由文章最后一段中“For many years, companies have been saying they’ve created apps that can ‘translate animals’, but many of these have been unbelievable or can only offer a very basic level of communication. The development of AI systems and deep learning algorithms (算法) has advanced the idea of using big data to make some kind of dictionary of animals’ vocabulary.”可知,作者认为使用人工智能进行动物翻译是有希望的,但需要更多的发展。故选A。 Ⅵ.1.Seeing the close bond　2.more than just a virtual companion 3.who had helped them through the tough times　4.time going by 5.was grateful to　6.to cherish every moment with her dad 学科网（北京）股份有限公司 $ Period Three　Lesson 2 Apps ●Ⅰ 单词拼写(每小题1分,满分8分) 1.Nowadays , people are eager to get the 　　　　　(最新的) information about the products they are interested in.  2.If you 　　　　　　　　(订阅) to this newspaper, you’ll get an extra magazine.  3.Virtual Reality 　　　　　　　(设备) are becoming more and more popular among young people.  4.The 　　　　　　(材料) used to make this product is indeed of high quality.  5.The 　　　　　(性别) of a person should not decide their opportunities in education and employment.  6.She quickly pressed the 　　　　　(按钮) on the remote control to change the TV channel.  7.A variety of e　　　　arose during the experiment , making it difficult to draw accurate conclusions.  8.The selection of g　　　　 in this supermarket is very wide, which can meet different customers’ needs.　  ●Ⅱ 单句填空(每小题1.5分,满分12分) 1.The hotel offers comfortable 　　　　　　(accommodate) with stunning views of the ocean from every room.  2.We received 　　　　　　　　(confirm) from the hotel that our reservation has been successfully made for next weekend.  3.The 　　　　　　　(power) image in the advertisement really caught my attention, making me want to explore more about the product.  4.Nowadays , the growth of food 　　　　　(deliver) apps is drowning the country with takeout containers and plastic bags.  5.She seemed confident but in 　　　　(real) she felt extremely nervous.  6.The teacher tries to 　　　　　(sure) that every student has the opportunity to show their creativity in class.  7.The 　　　　　　　　(favour) conditions allowed the team to complete the project ahead of schedule.  8.It is estimated that China accounts 　　　　70 percent of global silk production.  ●Ⅲ 短语填空(每小题2分,满分10分) 1.The term “AI” is often used 　　　　　　(简称) when referring to artificial intelligence.  2.Learning that a volunteer is needed for an exhibition of traditional Chinese painting, I am writing to 　　　　　(申请) the post.  3.Our programme has attracted hundreds of regular listeners ever since it 　　　　　(被建立) two years ago.  4.　　　　　　　　　　　(考虑) the rapid development of technology nowadays , more and more people are relying on digital devices for work and daily life.  5.I am 　　　　　　　　(赞同) the new plan because it seems more sensible and can have a positive impact on our project.  ●Ⅳ 句型训练(每小题3分,满分9分) 1.如果你想尽快康复,务必听从医生的建议。 　　　　　　　　　　　　　　　 if you want to recover quickly.

Recently, it announced Expressive Avatars, which can show a lot of lifelike human feelings. These avatars are part of what Synthesia calls its “digital actors”. They have improved facial expressions and human-like voices—an upgrade from other AI systems’ robotic sounds. Synthesia offers more than 160 AI avatars, under the agreement of real human actors. Users can produce videos in more than 130 languages. CEO Victor Riparbelli said that they are not coming for Hollywood; instead, they focus on companies and B2B content, which need communication videos that are easy-to-create and human-like, such as in areas like health care. Synthesia’s Expressive Avatars are powered by its Express-1 AI model. It was trained only on content produced in-house, avoiding false data (数据). Riparbelli explained that the company hired thousands of actors to record videos for the model to ensure exactness. The show presented an avatar reacting to words like “I am happy”. The avatars’ speech style is more natural than previous models. Riparbelli said,“Whether the conversation is cheerful or serious, our avatars change their performance accordingly, showing a level of care and understanding that was once the special area of human actors.” The possible misuse of this technology is a concern, especially considering the risks of deepfake (深度伪造) technology. “We’ve taken additional steps to prevent the misuse of our technology, including updating our policies to limit the type of content people can make, working on the early finding of dishonest actors, and increasing the teams that work on AI safety,” the company said in an announcement. Synthesia believes that Expressive Avatars will help businesses produce videos that are not only informative but also caring. Riparbelli said,“I think we’re looking at an important shift in capabilities within the next six to nine months.” (　)1.What is special about Expressive Avatars? A.They show facial expressions. B.They are more human-like. C.They can update themselves. D.They are good at language translation. (　)2.What does Synthesia use to train its Express-1 AI model? A.Videos of real actors. B.Data from the Internet. C.Sounds of other AI robots. D.Speeches from previous models. (　)3.Why is Synthesia’s announcement mentioned in Paragraph 5? A.To list some examples of misuse. B.To explain its advantages in technology. C.To show its efforts to deal with the risks. D.To encourage users to create more content. (　)4.What is the author’s attitude towards the Expressive Avatars technology? A.Objective.　　　　B.Doubtful. C.Confident. D.Uncertain. B Do you ever look at your dog, or cat, or a bird flying by the window and wonder, “What on earth are you thinking?” So many of us regard the animals around us as extensions (延伸) of ourselves, having long and deep conversations with our animal friends and supposing they can completely understand everything we are saying to them. The gap between human and non-human communication is still huge. But will there ever be a time when we’ll be able to talk to animals and they can reply in the same way? While it seems to be fantastic, could AI and new technologies further the development of animal translation? Animals communicate by a wide variety of different means. Most of this communication is message passing between the same species, but between-species communication is also rich. Think of an insect or fish changing colour to warn off attackers or remind them of their toxicity (毒性). But can these happen between humans and other animals? Any dog owner knows that if you shout at a dog for some wrongdoing, the dog knows it is being told off and answers accordingly. But there is a danger in thinking that animals can fully understand human communication. We human beings have our own awareness and specific human experience. The rest of the animal kingdom experiences the world in a way quite different from ours. So, even if we could understand what their calls mean, would we be able to catch what they are trying to say? So how can developing technologies help in our understanding of animals? For many years, companies have been saying they’ve created apps that can “translate animals”, but many of these have been unbelievable or can only offer a very basic level of communication. The development of AI systems and deep learning algorithms (算法) has advanced the idea of using big data to make some kind of dictionary of animals’ vocabulary. (　)5.What is the writer’s main purpose in Paragraph 1? A.To stress the importance of animals’ behaviour. B.To express curiosity about animals’ thoughts.
