impressive qualification. It is the first in the world to take old T-shirts and transform them into brand new ones,

where the finished shirts are distributed to Marine Layer’s 41 stores and online shops.

___4___ Each shirt varies slightly in color. No water, chemicals, or dyes are used in production. Best of all,

in their old shirts using a prepaid mailer, and will get $5 credit for each one, up to a total of $25.

data.___8___it is often used to write financial reports. Some newspapers also use AI to report on stories about

natural disasters, which mainly require basic facts such as “where” and “when”. As Forbes wrote, instead of losing

their jobs, journalists can make their work more efficient by using AI so that they can focus more on storytelling

and less on numbers.

new dances. For him, AI is a powerful tool that can help choreographers break out of common movements.

（2022·江苏省天一中学高二期末）Metaverse (元宇宙)

right place. Here, we’ll try to answer some big questions from Microsoft’s point of view. What is a metaverse?

Does it already exist? ____16____ Let’s dig in.

Simply put, a metaverse is a digital space inhabited by digital representations of people, places and things.

Think of it like a new version, or maybe a new vision, of the Internet. ____17____ Now we can actually go into

that place to communicate, share, and work with others. It’s an Internet that you can actually interact with — like

we do in the physical world.

And it’s not just a vision anymore. Right now, you can go to a concert and experience a show with other real

people inside a video game. ____18____ Those are metaverses. And the future is already here!

____19____ “But my digital self is not my physical self.” Well that is technically true. But Microsoft is

working to help you better represent your whole self in the digital space, while also ensuring that you can bring

your humanity and your agency over with that representation.

If the past few years have taught us anything, it’s that we need flexibility. The world has never been more

connected, but lately, we’ve often needed to distance ourselves physically. The closer we can reflect our physical

selves in the digital world, the more of these barriers we can break down. Teammates can join meetings from

anywhere. Real-time translation allows people from diverse cultures to collaborate in real-time. ____20____ The

metaverse has the ability to take us beyond the barriers and limitations of the physical world.

A．And are you already in it?

B．Have you been lost in a metaverse?

C．However, there’s some doubt about them.
