Hubei has started giving digital ID numbers to humanoid (人形的) robots. These robots are the first ones in China to have such special IDs.

Each robot ID is made up of 29 numbers and letters. Just like our ID numbers, each robot’s ID is unique. The system stores lots of key information, such as the robot’s maker, type and basic settings.

With the digital ID, workers can easily check the robot’s daily use, battery condition and repair history. If a robot goes wrong, people can quickly find out the problem and fix it. New users can also learn about the robot’s past use easily. This is very helpful if someone wants to buy or use a used robot.

Many local robot companies have completed the ID registration (注册). Their robots work in factories, shops and training places. This system helps cut costs and makes it easier to reuse robots.

1.1.How many characters does each robot ID have?

A 30.

B 28.

C 29.

D 35.

解析：选C。C细节理解题。根据文章第二段第一句“Each robot ID is made up of 29 numbers and letters.”可知，每个机器人身份证由29个数字和字母组成，因此直接选择C。A、B、D选项的数字均与原文不符，不选。故选C。

2.2. What does the underlined word “unique” mean?

A The only one.

B Very useful.

C Easy to remember.

D Quite new.

解析：选A。A词义猜测题。画线词所在句子提到“Just like our ID numbers, each robot’s ID is unique.”，将机器人ID比作我们的身份证号码，身份证号码具有唯一性，由此可推 unique 意为“唯一的，独一无二的”。B项“非常有用的”、C项“容易记住的”和D项“相当新的”均无法由身份证号的类比合理推出。故选A。

3.3. Why can new users trust a used robot with an ID?

A They can check its past use.

B They can get it for free.

C They can change its settings.

D They can talk to its maker.

解析：选A。A细节理解题。根据文章第三段最后两句“New users can also learn about the robot’s past use easily. This is very helpful if someone wants to buy or use a used robot.”可知，新用户通过这个ID可以轻松了解机器人的过往使用情况，所以才会信任有ID的二手机器人。B项“可以免费获得”和C项“可以更改设置”在文中均未提及；D项“可以和制造者交谈”文中也未涉及。故选A。

4.4. What will the ID system bring to the industry?

A Slow growth.

B Better development.

C More costs.

D Harder repair.

解析：选B。B细节理解题。文章最后一段最后一句明确指出“It will help the robot industry grow better in the future.”，即这个ID系统将助力机器人行业未来更好地发展，对应B项“更好的发展”。A项“缓慢增长”和D项“更难维修”与原文意思相反；C项“更多成本”与原文第三段中“helps cut costs”的说法不符。故选B。

5.5. What is the best title for the passage?

A Popular jobs for robots.

B History of robots.

C Robot production ways.

D Special IDs for robots.

解析：选D。D主旨大意题。全文围绕湖北给机器人发放数字身份证这一事件展开，依次介绍了ID的构成、作用和意义，核心话题就是机器人的特殊ID，因此D项“机器人的特殊身份证”是最佳标题。A项“机器人的热门工作”文中仅简单提及工作场所，并非重点；B项“机器人的历史”完全未涉及；C项“机器人的生产方式”也未讨论，它们都不能概括全文主旨。故选D。
