Scientists from Shanghai Jiao Tong University are developing a robot “guide dog” to help blind(盲的) people.
The robot is now being tested in Shanghai. With the help of cameras and AI, the robot “guide dog” can see, listen and speak with blind people. It can help them during daily trips outside and be their “friend” at home.
Blind people can also use a cane(手杖) to control the robot’s walking and running speed. The robot can even recognize traffic signals(识别交通信号).
The robot “guide dog” is as large as an English bulldog but a little wider. It has six legs instead of four. The extra legs make it more stable(稳定的) and help it move faster.
41-year-old Li Fei and 42-year-old Zhu Sibin are helping test the robot. Li is totally blind and Zhu can only see a little. Zhu often uses a cane to move around, “The robot ‘guide dog’ makes it easier to get into public places than with a real guide dog. I am happy to join in the test. It could make our lives different in the near future,” Li said.
In China, there are about 17.31 million blind people, but there are only about 400 guide dogs. The new robot is trying to solve this problem. “We believe our robot will act as ‘a pair of eyes’ for blind people,” said Professor Gao Feng, one of the scientists. He thinks there will be a large market for these robot “guide dogs”.
1. The robot “guide dog” has extra legs .
A. to look more like a real dog

D. Telling stories.
3. What can we infer from the last paragraph?
A. It takes time to perfect the robot.
B. More real guide dogs will come out.
C. The robot will help the blind a lot.
D. The blind love robots now.
4. What may be the best title for the passage?
A. Guide dogs with six legs
B. A robot guide dog for the blind
C. Smart robots from Shanghai
D. A new cane for the blind

B
【语篇导读】本文主要介绍了上海交通大学的科学家研发的机器导盲犬,包括其功能、外形特点、测试情况以及社会意义。
1. D 提示:细节理解题。根据第四段最后两句“It has six legs instead of four. The extra legs make it more stable and help it move faster.”可知,机器导盲犬多出的腿使其更稳定、移动更快。
2. A 提示:推理判断题。根据第五段第一句“41-year-old Li Fei and 42-year-old Zhu Sibin are helping test the robot.”可知,该段通过列举具体人物事例来说明机器导盲犬的测试情况,属于举例子的写作手法。
3. C 提示:推理判断题。根据最后一段第一、二句“In China, there are about 17.31 million blind people, but there are only about 400 guide dogs. The new robot is trying to solve this problem.”可知,中国盲人数量多但导盲犬数量少,这款新机器人正试图解决这个问题,随后科学家表示机器人将为盲人充当“眼睛”,由此推知,机器导盲犬将对盲人有很大帮助。
4. B 提示:标题归纳题。通读全文,文章主要介绍了上海交通大学的科学家研发的机器导盲犬,包括其功能、外形特点、测试情况以及社会意义。由此可见,文章以B项“为盲人设计的机器导盲犬”作为标题最合适。
长难句分析
Scientists from Shanghai Jiao Tong University are developing a robot "guide dog" to help blind people.
译文:上海交通大学的科学家们正在研发一款机器“导盲犬”,以帮助盲人。
分析:本句是简单句。
主语:Scientists from Shanghai Jiao Tong University,其中介词短语 from Shanghai Jiao Tong University 作后置定语修饰 Scientists。
谓语:are developing。
宾语:a robot "guide dog"。
同位语:"guide dog",补充说明 robot。
目的状语:to help blind people。

【分析】
本题为科技类阅读理解，共4道小题，分别考查细节理解、写作手法、推理判断、标题归纳。解题思路如下：1. 细节理解题需准确定位原文对应段落，找到题干相关信息；2. 写作手法题需分析段落结构，判断使用的说明方法；3. 推理判断题需结合上下文信息，合理推断隐含内容；4. 标题归纳题需概括全文核心内容，选择最贴合主旨的选项。
【解析】
1. 细节理解题：根据第四段最后两句“It has six legs instead of four. The extra legs make it more stable and help it move faster.”可知，机器导盲犬多出的腿是为了更稳定、移动更快，故选D。
2. 写作手法题：第五段通过列举Li Fei和Zhu Sibin参与机器人测试的具体事例，说明机器导盲犬的测试情况，属于举例子的写作手法，故选A。
3. 推理判断题：最后一段指出中国盲人数量多但导盲犬数量少，新机器人正试图解决这一问题，科学家称机器人将为盲人充当“眼睛”，由此可推断机器导盲犬会对盲人有很大帮助，故选C。
4. 标题归纳题：全文围绕上海交通大学研发的机器导盲犬展开，介绍了其功能、外形、测试情况及社会意义，B项“为盲人设计的机器导盲犬”最能概括主旨，故选B。
