1 . What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.

Liu Lei	I think AI will be more useful in our future lives. It’s now used in many fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I’m sure AI will help us solve many problems.
Xu Lu	I’m worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced (取代) because AI robots will do a lot of work instead of people.
Zhao Mingming	I really think that Al will change the way we work, the way we live, and the way we think. Imagine if we could put a CPU into our brains! Soon we’ll be able to improve our math and memory. How exciting!
Molly	Think of what’s happening now. Some robots are used to kill animals. So I think AI will be very dangerous for humans, too. We need to be careful about what we ask machines to do.

1. Why does Xu Lu think that humans may be replaced?

A．Because humans are smarter than AI.

B．Because AI robots will do lots of human jobs.

C．Because humans will put a CPU into our brains.

D．Because we can’t improve our math and memory.

2. What does Molly think of the future of AI?

A．AI will be more useful for people.	B．AI will be less useful for people.
C．AI will be dangerous for people.	D．AI will be important for people.

3. ______ believe that AI will be a good thing?

A．Liu Lei and Xu Lu	B．Liu Lei and Zhao Mingming
C．Xu Lu and Molly	D．Zhao Mingming and Molly

2 . We don’t know how different our life will be in the future. We can only try to imagine it.

At first we think about human relationship. In the year 2050, we will use computers almost every day. We will make new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today—we will feel a little lonely.

Computers will also help us in many other activities in 2050.For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will use solar-powered cars, which will be much cleaner.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.

Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future；we have expectations, hopes as well as fears. But I think we should be rather hope about our future. We should be happy and believe good things will happen.

1. Why will people probably feel a little lonely in 2050?

A．Because the number of people will become much smaller.

B．Because there will be less face-to-face communication.

C．Because people won’t like making friends with each other.

D．Because people won’t communicate with each other much often.

2. The third paragraph mainly tells us         .

A．computers will do all the things for human beings

B．how people will use computers to communicate with each other

C．machines like computers and robots will help people a lot

D．how people will use robots to do the housework

3. What does the passage mainly talk about?

A．How people will communicate in the year 2050.

B．What our life will be like in the year 2050.

C．How people will travel and spend their holidays in the year 2050.

D．What high technology will appear in the year 2050.
