Brooke wanted a dollhouse and some sugar...

    Brooke wanted a dollhouse and some sugar cookies. So the 6­year­old Brooke asked Alexa to get them. It was a voice­activated home assistant powered by AI. And it made Brooke's wishes come true.

Alexa isn't the only AI willing to serve you. Apple Homepod has Siri, Google Home has its Assistant, 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, even if you are cooking, cleaning, or driving.

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. So they listen for “Alexa” or “OK Google” or another order. When they hear it, they start recording the conversation. Some have worried about what happens to these recordings. Should companies be allowed to use them to learn about people's shopping habits? And what if someone hacks the device? The CIA found a way to hack smart TVs to turn them into spies that listen all the time. 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 recorded when trying voice shopping?

A.Paragraph 1. B.Paragraph 2.

C.Paragraph 3. D.Paragraph 4.

5.What is the best title for the passage?

A.The advantages and disadvantages of voice shopping

B.The voice­activated home assistant—Alexa

C.The convenience of AI

D.Brooke's wishes
