III. Choose the best answer and complete the passage (选择最恰当的内容完成短文)
“Industry 4.0” is a mix of low-cost and high-power computers, high-speed communication and artificial intelligence. This will produce smarter robots with better sensing and communication abilities. 1 robots focused on single, fixed, high-speed operations and required a highly skilled human workforce to operate and maintain them. Industry 4.0 machines are flexible, cooperative and can operate more independently, which 2 removes the need for a highly skilled workforce.
For large-scale manufacturers, Industry 4.0 means their robots will be able to sense their environment and communicate in an industrial network that can be run and 3 remotely. Each machine will produce large amounts of data that can be 4 studied using what is known as “big data” analysis. This will help 5 ways to improve operating performance and production quality across the whole plant, for example, by better predicting when repair is needed and automatically scheduling it.
For 6 manufacturing businesses, Industry 4.0 will make it cheaper and easier to use robots. It will create machines that can be rearranged to perform 7 jobs and adjusted to work on a more diverse product range and different production volumes.

People often ask smartphones questions and expect quick answers. So what makes humans trust smart machines Researchers want to know.
A team of researchers set up an e 1 They wanted to find out how a robot best learns to do a certain task. They also hoped to learn how a robot can best explain its actions to w 2 humans' trust. The engineers built a robot. Then they gave it a task. It had to open a safety- locked medicine bottle. First, a person showed the robot how to do it. The person wore a special glove that measured his hand positions and the forces he used to open the bottle.
E 3 time the person's hand moved, an action word described it. For example, words like "push" or "twist" were used. This was symbolic information. The robot needed this information to know how to open the bottle. Then researchers gave the robot the bottle. But it h 4 ever got the bottle open. Why did it fail
The robot had the symbolic information it needed. But it didn't have the haptic (触觉的)information. The researchers left that out. What's haptic information It has to do with what you feel when your body moves. For example, humans don't just grasp and twist safety- locked bottles. We squeeze the cap tightly. We feel when the cap jams. Then we change our force until we l 5 the cap. The robot tried again. This time it had symbolic and haptic information. Success The robot opened the bottle.
An audience of 150 people watched the robot open the bottle. The audience was put into groups. The robot gave each group a different e 6 of the task. One group was given both symbolic and haptic information. Some groups got only symbolic information. Other groups got only haptic information. And some groups got less information or none at all.
Which group trusted the robot the most The group that r 7 both the symbolic and haptic information. And they said the symbolic information helped them see the robot as trustworthy. It was more important to them than the haptic information.

AI is not going to replace humans, but humans with AI are going to replace humans without AI. Let's take magazine publishers as an example. There are some publishers who say they will not take articles or papers where generative AI has been involved. That doesn't make sense. AI is just a tool, like a search engine. What we' re saying though is that the responsibility is on the person with the byline on this piece. Nobody would like to use just search results. We need to verify and do a little bit more. Learn to improve the professionals with the help of AI, which is the most important thing.

II. One possible version:
In my opinion, social media has more disadvantages than advantages.
While it connects us with others, it often leads to excessive screen time, reducing productivity and interfering with studies or hobbies. Moreover, social media platforms can cause many serious problems.
For example, many news stories on social media have later turned out to be false. Sharing real-time photos may lead to privacy leaks. Additionally, scientists warn that using too much phone may cause a decline in mental health, leading to feelings of anxiety.
Thus, I believe the negative effects of social media outweigh its benefits, so we should be careful in its use.
Another possible version:
I believe social media is a positive tool that enhances our lives. It allows us to stay connected with friends and family, no matter where they are.
For example, during holidays, we can share travel photos, letting our friends and family share our happiness in real- time. Additionally, social media helps us meet new people from around the world and broadens our horizons. It also provides easy access to news and educational content.
Therefore, when used wisely, social media offers valuable benefits that enrich our daily lives.
