Tired of standing in line? Wait a bit longer, and you may never have to again. Everyone from Amazon to Silicon Valley startups is trying to lines in retail stores.
Amazon has opened 24 of its Amazon Go stores, which use cameras and artificial intelligence to see what you've taken off shelves and charge you as you walk out. Some startups are closely copying Amazon's approach to using AI-powered cameras fixed in ceilings. But others are trying an entirely different way to skip the checkout: smart shopping carts. These companies have added cameras and sensors to the carts, and are using AI to tell what you’ve placed in them. A built-in scale weighs items, in case you have to pay by the pound for an item. Customers pay by entering a credit card, or through an online payment system. When a customer exits the store, a green light on the shopping cart indicates that their order is complete, and they’re charged.
The startups behind the smart carts, including Caper and Veeve, say it’s much easier to add technology to the shopping cart than to an entire store. Amazom's Go stores rely on hundreds of cameras in the ceiling. The shelves also include sensors to tell when an item is removed. Ahmed Beshry, co-founder of Caper, believes the technology to run Go is too expensive to use in a large format grocery store. Neither Caper nor Veeve have said how much their smart shopping carts will cost, making it difficult to compare the different formats. Shariq Siddiqui, CEO of Veeve, said he’s finding increased interest from retailers given Amazon’s steady expansion of Go since opening the first store in Seattle in 2018. “We’re always happy when Amazon is doing something,” Siddiqui said. “They force retailers to get out of their old school thinking.”
Each time a business uses artificial intelligence and cameras, it raises questions about customer privacy and the impact on jobs. Beshry notes that the cameras in his shopping cart point down into the cart, so only a customer’s hand and part of their arm will be captured on camera.
1.What do we know about the smart shopping carts?
A.They are linked to the cameras fixed in the ceilings.
B.They can tell customers where to find what they want.
C.They flash the green light when the order is cancelled.
D.They are able to recognize purchases placed in them.
2.What does Beshry think of the technology applied in Amazon’s Go stores?
A.It is far more expensive than their shopping carts.
B.It may increase the cost of running a store greatly.
C.It has attracted many more retailers than before.
D.It is likely to help retailers to think differently.
3.What is the best title for the text?
A.The New Technology Promotes Retail Sales
B.AI-powered Cameras Are Used in Retail Stores
C.Smart Shopping Carts Will Let You Skip the Line
D.Artificial Intelligence Affects the Future Job Market

Imagine you’re standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.
Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.
In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine. " Biometrics is ideally good in practice, not so much," said John Michener, a biometrics expert.
When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. "The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.
"We may expect too much from biometrics," Anil Jain, a computer science professor at Michigan State University, told CBS News. "No security systems are perfect."
Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."
1.Which is the latest identification technology in a smart phone according to the passage?
A. Face scanning. B. Eye scanning.
C. QR Code scanning. D. Fingerprint scanning.
2.What is a major problem of the iPhone X's face ID system?
A. It takes too long to unlock the phone.
B. It often fails to recognize its owner's face.
C. Face data can be used for other purposes.
D. Different faces can be used to unlock the same phone.
3.What is Anil Jain's opinion about biometric security?
A. It is as secure as traditional measures.
B. It is perfect without much improvement.
C. It has caused much trouble for the police.
D. It should be used with other security measures.
4.What does the author intend to tell us in this passage?
A. The popularity of biometrics.
B. Security problems of biometrics.
C. Various problems with biometrics.
D. Great changes caused by biometrics.

Tired of all the pushing in supermarkets? Fed up with waiting in endless lines to pay for what you have bought? Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store? If this is you, then online shopping is the answer to your dreams of trouble-free shopping. Or is it?
Online shopping brings its own challenges. Here are a few things to bear in mind when browsing (浏览) various websites. The claim made by online sites is that shopping online is a safe and secure way to make purchases. The evidence challenges this. In any case, you only have to be the victim of fraud (诈骗) once to experience all the problems that come with this form of stealing. Use only sites that have a trusted history and an excellent reputation.
Another problem is the appearance of items in reality is often quite different from what you see on your computer screen. This might not be a problem if you are buying washing up powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green. Also, product descriptions are sometimes simply untrue. Perhaps the wisest plan is to purchase items where design and color are not essential to customer satisfaction.
Some even argue that online shopping indirectly contributes to global warming. Yes, your car can stay parked but how are online goods delivered? Often by some large vans pouring out carbon monoxide and adding to our already desperate traffic problems. You are also by now becoming increasingly irritated (使烦恼) by the fact that the delivery is late and you have wasted the leave from work you have taken to receive it!
Without question, online shopping is here to stay and it has its benefits. However, perhaps it is not as wonderful as some of its supporters claim it to be.
1.The author lists several questions in Para. 1 to .
A. support online shopping
B. collect answers from readers
C. show his dislike of going shopping
D. introduce the topic of the passage
2. By what can online shoppers avoid fraud?
A. Using only trusted websites.
B. Choosing big websites.
C. Collecting shopping evidence.
D. Seeking advice from the police.
3.The author agrees with the fact that ______.
A. customers are never satisfied with products
B. online shopping is a safe way to make purchases
C. online shopping has nothing to do with global warming
D. delivery delay often makes online shoppers unhappy
4.What is the author’s attitude towards online shopping?
A. Very popular. B. A wise choice.
C. Not trouble free. D. A waste of time.

Tell a story and tell it well,and you may open wide the eyes of a child,open up lines of communication in a business,or even open people’s mind to another culture or race.
People in many places are digging up the old folk stories and the messages in them.For example,most American storytellers get their tales from a wide variety of sources,cultures,and times.They regard storytelling not only as a useful tool in child education,but also as a meaningful activity that helps adults understand themselves as well as those whose culture may be very different from their own.
“Most local stories are based on a larger theme,”American storyteller Opalanga Pugh says,“Cinderella(灰姑娘),or the central idea of a good child protected by her goodness,appears in various forms in almost every culture of the world.”
Working with students in schools,Pugh helps them understand their own cultures and the general messages of the stories.She works with prisoners too,helping them know who they are by telling stories that her listeners can write,direct,and act in their own lives.If they don’t like the story they are living,they can rewrite the story.Pugh also works to help open up lines of communication between managers and workers.“For every advance in business,”she says,“there is a greater need for communication.”Storytelling can have a great effect on either side of the manager-worker relationship,she says.
Pugh spent several years in Nigeria,where she learned how closely storytelling was linked to the everyday life of the people there.The benefits of storytelling are found everywhere,she says.
“I learned how people used stories to spread their culture,”she says.“What I do is to focus on the value of stories that people can translate into their own daily world of affairs.We are all storytellers.We all have a story to tell.We tell everybody’s story.”
1.What do we learn about American storytellers from Paragraph 2?
A.They share the same way of storytelling.
