Researchers in Shanghai are developing a robot “guide dog” that could help blind people. The robot is now being tested in Shanghai.
The machine uses cameras and sensors(传感器) to sense its environment. It is able to recognize(识别) traffic lights which traditional guide dogs are unable to recognize. The robot can communicate by listening to and speaking with a blind person. The robot also uses artificial intelligence(AI) to recognize voices and plan ways to go from place to place.
The robot dog is about the size of an English Bulldog but a little wider than a real dog. It has six legs instead of four because the researchers say the extra legs enhance its safety, making its movements smoother.
42-year-old Li Fei and 43-year-old Zhu Sibin are among the people with eye problems who are helping Shanghai Jiao Tong University's team. They are testing the dog using Chinese-language instructions and providing their feedback(反馈) for the researchers to further develop the dog.
Li is completely blind while Zhu has little eyesight. Li normally uses a walking stick to walk. She said, “If this robot guide dog comes onto the market, I will use it. At least it could solve some of my problems in traveling alone.”
Robot guide dogs are also under development in Australia and Britain. But China needs a lot of guide dogs. There are just over 400 traditional guide dogs in China for nearly 20 million blind people.
Many workplaces, restaurants and public areas do not welcome a usual guide dog like a Labrador. The supply of real dogs is limited by feeding and training needs. The production of robot guide dogs could be increased to an industrial level, especially in a manufacturing industry center like China. The researchers think there could be a large market for robot guide dogs as there might be tens of millions of people in the world who need guide dogs.
1.What is one advantage of the robot guide dog according to the text
A.It can work at any time.　　　　B.It follows the traffic lights.
C.It costs much less.　　　　D.It can find the way more easily.
2.What does the underlined word “enhance” in paragraph 3 mean
A.Report.　　　　B.Record.　　　　
C.Show.　　　　D.Increase.
3.Why are Li Fei and Zhu Sibin mentioned in the text
A.They prefer experiencing modern inventions.
B.They're experts in developing robot guide dogs.
C.They play a part in improving robot guide dogs.
D.They depend on real guide dogs for traveling around.
4.What is the future of robot guide dogs like according to the researchers
A.Worrying.　　　　B.Challenging.　　　　
C.Uncertain.　　　　D.Hopeful.

Happiness is not a warm phone, according to a new study exploring the link between young people's life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University(SDSU).
To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with a variety of data from the Monitoring the Future(MtF) study, a nationally representative survey of more than a million U.S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how much time they spent on their smartphone, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.
On average they found that teens who spent more time in front of screens—playing computer games, using social media, texting and video chatting—were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions.
“The key to digital media use and happiness is limited use,” Twenge said. “Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising—two activities reliably linked to greater happiness.”
Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of electronic devices over time happened at the same time as a general drop-off in reported happiness in U.S. teens. Specifically, young people's life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on screens, and the decline in in-person social activities and sleep.
5.Which method did Twenge's team use for the study
A.Calculating students' happiness. 　　　　
B.Asking students certain questions.
C.Analyzing data from a survey. 　　　　
D.Doing experiments on screen time.
6.How does the author develop the finding of the study in Paragraph 3
A.By making a comparison. 　　　　B.By giving an example.
C.By making an argument. 　　　　D.By introducing a concept.
7.What is the purpose of the last paragraph
A.To draw a conclusion from the study. 　　　　
B.To offer some advice to the readers.
C.To prove social activities' importance. 　　　　
D.To support the researchers' finding.
8.Which of the following can be the best title for the text
A.Quitting Phones Equals Happiness　　　　
B.The Use of Screens Should Be Banned
C.Teens' Lives Have Changed Sharply　　　　
D.Screen-addicted Teens Are Unhappier

The Future of AI Might Look a Lot Like X
Have you ever shared a serious opinion on social media, only to receive no response—or worse, be made fun of 　1　
At first glance, SocialAI seems like any other social media platform.　2　 However, the key difference is that you're the only real person on the platform; everyone else you interact with is an AI bot.
You can customize different personas, such as “supporters”,“nerds”,“skeptics”,“visionaries”or “ideators”. Thousands of bots will like and comment on each of your tweets, with responses that appear to come from real people. 　3　 However, many users have discovered that the bots tend to respond in a standard format, offering comments that lack real depth and are shaped by their assigned personas. 　4　
　5　 “SocialAI is designed to give people space for reflection, support, and feedback that acts like a close-knit community,” he wrote in a tweet. However, he acknowledged, “I know this app won't solve all of life's problems, but I hope it can be a small tool for others to reflect, to grow, and to feel seen.”
A.Sounds great, doesn't it
B.You can post tweets, follow others, and gain followers in turn.
C.But most of all, it's an attempt to build an entirely new way to interact with AI models.
D.After years of waiting and months of testing the latest models, Sayman invented SocialAI.
E.The app's creator, Michael Sayman, explained that he developed SocialAI to help people feel heard.
F.This can make users feel as if they're living in a simulation(模拟) world, much like the setting of the 1998 movie The Truman Show.
G.A new app called SocialAI has emerged to potentially ease such awkwardness and disappointment.

分析　本句为主从复合句。that引导宾语从句,其中有两个who引导的定语从句,分别修饰teens和those,“playing computer...video chatting”解释青少年花更多时间在屏幕前的具体方式,like为介词,举例说明非屏幕活动。
译文　平均来看,他们发现,在屏幕前花费更多时间——玩电脑游戏、使用社交媒体、发短信和视频聊天——的青少年不如那些在体育、阅读报纸和杂志及面对面社交互动等非屏幕活动上投入更多时间的青少年快乐。
5.C　细节理解题。根据第二段第一句中的“To research this link...dealt with a variety of data from the Monitoring the Future(MtF) study”可知,为了研究这一联系,Twenge与圣地亚哥州立大学的Gabrielle Martin和佐治亚大学的W. Keith Campbell一起处理了来自“监测未来”研究的数据。由此可知,Twenge 的团队通过分析一项调查的数据的方式来进行这项研究。故选C。

长难句
原句　However, many users have discovered that the bots tend to respond in a standard format, offering comments that lack real depth and are shaped by their assigned personas.
分析　本句为主从复合句。第一个that引导宾语从句,其中“offering comments that lack...personas”为现在分词短语作状语,其中that引导定语从句,修饰先行词comments。
译文　然而,许多用户发现,机器人往往以标准的格式回应,提供的评论缺乏真正的深度,而且受它们所指定的角色的影响。
1.G　空前通过提问的形式引出本文的话题,结合空后的“At first glance, SocialAI seems like any other social media platform.”可知,设空处讲述的内容应引出SocialAI这一概念,G项“一款名为SocialAI的新应用程序已经出现,可能会缓解这种尴尬和失望”符合语境,其中的“awkwardness and disappointment”与空前提到的情况吻合。故选G。
2.B　根据空前的“At first glance, SocialAI seems like any other social media platform.”可知, 乍一看SocialAI与其他社交媒体平台无异,结合空后的“However, the key difference is...”可知,空后的内容与设空处的内容为转折关系,结合选项可知,B项“你可以发推文,关注别人,相应地也能获得关注者”承接上文,说明SocialAI和其他社交媒体相同的地方,且与空后的内容形成转折。故选B。
3.A　根据空前的“You can customize different personas...with responses that appear to come from real people.”可知,AI机器人会点赞和评论用户的每条推文,使回复看起来像是来自真实的人;根据空后的“However, many users have discovered that the bots tend to respond in a standard format, offering comments that lack real depth and are shaped by their assigned personas.”可知,这些机器人的回复往往缺乏深度。结合选项可知,A项“听起来很棒,不是吗 ”承接上文,评价机器人的智能回复,且与空后的内容构成转折关系。故选A。
4.F　根据空前的“However, many users have discovered...offering comments that lack real depth and are shaped by their assigned personas.”可知,这些机器人的回复往往缺乏深度而且受所指定的角色的影响,结合选项可知,F项“这会让用户感觉他们好像生活在一个模拟世界中,非常像1998年的电影《楚门的世界》的背景”承接上文,通过类比电影的背景,进一步说明这一应用的不足之处。F项中的This指代上文描述的情况。故选F。
5.E　空后内容介绍了SocialAI的设计初衷,E项“这款应用的开发者Michael Sayman解释说,他开发SocialAI是为了帮助人们感到被倾听”提到了这款应用的开发者Michael Sayman,引出下文,符合语境。故选E。
