Brooke wanted a dollhouse and some sugar...

    Brooke wanted a dollhouse and some sugar cookies. So he asked Alexa to get them. It was a voice-activated home assistant powered by AI. A few days later, a $170 dollhouse and four pounds of cookies showed up.

Alexa isn't the only AI willing to serve you. Apple HomePod has Siri, and the upcoming Galaxy Home device will have Bixby. People who have these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, nowadays voice shopping is rare. But many scientists predict a boom in voice shopping in the near future.

Convenience is the main advantage of voice shopping. You can shout out an order as soon as you think of it. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without any help.

But voice shopping has its disadvantages. Unwanted dollhouses aren't the biggest problem. It's usually very easy to cancel an order or return products. The thing that worries some people is that these assistants are always listening. They have to be able to respond when you want them. Some have worried about what happens to these recordings. The CIA found a way to hack smart TVs to turn them into spies that listen. Others could do the same with any smart device. What do you think? Are you ready to start voice shopping?

1.From the passage, we know that Alexa ________.

A.can look after the baby B.can cook delicious food

C.is a toy doll sold online D.is one kind of AI device

2.What does the underlined word "rare" mean in Chinese?

A.罕见的 B.昂贵的 C.有害的 D.不可能的

3.What's the main advantage of voice shopping?

A.Its speed. B.Its price. C.Its quality. D.Its convenience.

4.Which paragraph tells us that personal information might be hacked when people try voice shopping?

A.Paragraph 1. B.Paragraph 2. C.Paragraph 3. D.Paragraph 4.

5.What's the best title for the text?

    The streets are quiet, and the stores are closed. There's the smell of fresh bread from a bakery somewhere. It would be hard to say which time of the day in Paris I prefer, but this probably is. Soon the streets will be full of people and traffic, and the real Paris will appear as the city wakes up. Under the city are hundreds of miles of tunnels. There are old subways and wine cellars that have been made into galleries. During the 19th century, farmers grew mushrooms in them. During World War , the French fighters also used them. Since the 1970s, groups of young people have spent days and nights there. Parties, theater performances, art galleries—everything goes here!

Everywhere you go under Paris, there is history and stories. Writers often write about the tunnels in their books. Victor Hugo mentions them in his famous novel—Les Miserables. There is an underground pool there—with fish! Tourists can visit parts of the Paris underground.

However, it's not allowed to enter other parts of the underground. However, there are people who will take you to visit them. I have found two “unofficial” tour guides—Dominique and Yopie. They take me through many tunnels, and after a couple of hours we arrive at a room which isn't on any map.

It's comfortable and clean, with a table, chairs, and a bed. Yopie tells me there are many other places like this. “Many people come down here to have parties. They like the room.”
