三、阅读理解

Imagine you walk into a store. Strangely enough, you see no staff inside. You pick up things and prepare to wait in line and pay. But even more strangely, there is no cashier（收银员 ) at all. So what has happened to this store?

Well, you may have entered Tao Cafe, a cashless store created by Chinese-commerce giant Alibaba. In July, the public got to see the store for the first time at Alibaba’s Taobao Maker Festival in Hangzhou.

The 200-square-meter store sells drinks, fast food and snacks. It can hold up to 50 shoppers at a time. To enter and shop, people only need a smartphone with a Taobao app and an Alipay account（账户）.

By scanning their Taobao QR code（二维码）, shoppers are followed with cameras for facial recognition（面部识别）. The store has also digitalized（数字化）all goods and their placement on the shelves. So when shoppers pick up goods, the system（系统）will be able to “watch” and “remember” their selection.

When shoppers are ready to leave, they don’t wait in line to pay. Instead, they go through two checkout（结账）doors. Then the bills will automatically（自动地）be paid with a Taobao account connected to Alipay.

According to Alibaba, the checkout machines can recognize goods even when shoppers put them in pockets or bags. So it is almost impossible to steal things from the store.

Tao Cafe is not the only cashless store in China. A 24-hour store with no staff called Bingo Box opened in Shanghai in June. To enter the store, shoppers scan a QR code on Wechat or Alipay. But unlike the Tao Cafe, they have to scan another QR code to leave the Bingobox.

26．Tao Cafe is known as _______

A．a coffee shop B．a cashless store C．an online store D．a Taobao Maker festival

27．To buy things from tao Cafe, you need to have all of the following EXCEPT ______

A．a smart phone B．a Taobao store

C．an Alipay account D．a Bingobox QR code

28．What are paragraphs 4 and 5 mainly about?

A．How to check out in Tao Cafe. B．Why Tao Cafe needs cameras.

C．How the system in Tao Cafe works. D．How shoppers can find goods easily in Tao Cafe.

29．What can we infer (推断) from the story?

A．The elders would enjoy shopping in Tao Cafe.

B．Lots of things will be lost in the cashless store.

C．Shopping at Bingobox is more convenient than at Tao Cafe.

D．It save people much time to shop at Tao Cafe.

六．例文

Technology plays an important role in our daily life. We benefit from them a lot and they are changing our lives greatly. Of hundreds of technological inventions, I like the high-speed train best.

In the past, it took me about 20 hours from Shenzhen to Shanghai . But now it only takes me about 4 hours to get to Shanghai. This saves me a lot of time. Moreover, it’s comfortable to take the high-speed train because it moves smoothly, and I can do some reading and watch movies without any problem. I can not only enjoy the view out of the windows but also have a relaxing time on the train. Many people choose to take the high-speed train because of the lower price than the plane. And it is very convenient. What a great creative invention!
