Amazon is breaking into physical retail in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code(二维码). They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt.

The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e-commerce company would expand its dominance from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

However, Amazon's move deeper into physical retail shops comes in a sensitive political climate. The company could be perceived as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. On the campaign trail, Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos for “getting away with murder tax-wise” and having “a huge antitrust(反垄断) problem.” Will the President& shy; elect add “job killer” to the list of criticisms?

Amazon's effort to launch a new kind of retail store predates(在……之前) the rise of Donald Trump. “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in early 2017.

1.In Amazon Go, people can ________ .

A. buy products by paying cash

B. buy carts without scanning a QR code

C. have no bother to check out and queue

D. use an app to wait in a checkout line

2.What can we infer from the third paragraph?

A. Amazon has dominated the physical bookstores.

B. Amazon can contribute to reducing the cost of staff.

C. Amazon manages to take the place of physical shopping.

D. Amazon can ignore each customer's advice in all situations.

3.The reason why Donald Trump repeatedly criticized Amazon Go is that Amazon Go　 ________ .

A. would result in a political crisis

B. would threaten the career of cashiers

C. may result in a huge antitrust

D. is No.1 job killer in the list of criticisms

4.The main purpose of writing the passage is　 ________ .

A. to introduce the Amazon Go store

B. to explain how Amazon Go works

C. to arouse people's interest in Amazon

D. to indicate Trump's attitude to Amazon

Square dancing is a form of entertainment and physical exercise, which is a good thing. However, a group of senior Chinese ladies dancing in New York’s Sunset Park were recently faced with noise complaints from nearby residents. The local court even served a summons (传票) related to a certain Ms. Wang.

The news soon caused heated discussion across China, with many believing the incident to involve a cultural conflict between the East and West,while others view it as a form of discrimination against Chinese in the United States.

The United States is a diverse society, and in many cases, Chinese dancers are tolerated and even appreciated. Meanwhile, the United States is a society based on the rule of law, and due to cultural differences, local regulations seem to be very different from those in China. As a result, some old Chinese ladies dancing in New York’s Sunset Park found themselves caught in an embarrassing situation. Locals and immigrants from other nations view such noise as a violation of their right to enjoy tranquility. Calling the police is regarded as the most efficient way to solve such a problem.

Before, these ladies probably did not understand local customs and rules. However, since the incident took place, they should perhaps know a little better next time and keep the noise to a minimum. People from different nations are often supposed to reach compromises, respecting and tolerating each other.

Whatever your choice of entertainment, it is important not to affect other people’s lives. Square dancing is only one of many activities during which people should mind their behavior.

As for U.S. police practice, there might still be some room for improvement. Some were said to be rather rude, leading to the so-called “racial discrimination,” which is a sensitive topic in U.S. society.

If the involved parties could be more tolerant, and solve such problems without involving the court, perhaps immigrants would mix more.

1.The writer mentions the incident in Paragraph 1 to __________.

A. show his opinion　　　　　 　 B. make complaints

C. bring up the topic　　　　　 　 D. criticize the local police

2.The underlined word “tranquility” in Paragraph 3 can be replaced by ________.

A. entertainment　　 　　　　 　 B. quietness

C. freedom　　　 　　　　　　　　 D. quality

3.What will the senior Chinese ladies most probably do after the incident?

A. Go back to China.

B. Fight for their right.　　

C. Ask America to change its law.

D. Keep the noise lower.

4.What’s the writer’s attitude towards senior Chinese ladies dancing in New York’s Sunset Park?

A. He thinks all parties involved should be more tolerant.

B. He strongly supports the action of the local police.

C. He considers it a shame for senior Chinese ladies to do so.

D. He suggests such kind of problem should be solved in the court.

Most young people enjoy some forms of physical activity. It may be walking, cycling, swimming, or in winter, skating or skiing. It may be a game of some forms—football, basketball, hockey, golf or tennis. It may be mountaineering.

Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks in high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity to which men give their leisure.

Mountaineering is a sport and not a game. There are no man-made rules, as others, as there are for such games as golf and football. There are, of course, rules of different kinds which would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

If we compare mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

A mountain climber continues to improve in skills year by year. A skier is probably past his best by the age of thirty. But it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they perhaps climb with more skills and less waste of effort, and they certainly experience equal enjoyment.

1.What sports are popular among people in winter in the passage?

A. Soccer and golf.　　　　　　　　 B. Skiing and skating.

C. Cycling and hockey.　　　　　　　 D. Mountaineering.

2.The underlined word “passion” in Paragraph 2 could best be replaced by _ _____.

A. strong emotion　　　　　　　　　　 B. good way

C. better feeling　　　　　　　　　　 D. enough affection

3.Mountaineering is a sport, not a game because_______.

A. it has man-made rules

B. it is too dangerous for climbers

C. it is free for climbers to use their own methods

D. it can’t bring people joy or leisure

4.We know from the passage that _______.

A. mountaineering has no appeal for people

B. physical quality is more important than mental one for climbers

C. a mountain climber passes his best by the age of thirty

D. it is possible for an old man of fifty or sixty to climb the Alps

5.What is the best title for the passage?

A. Sports in winter　　　　　　 B. Team work in climbing

C. Mountaineering　　　　　　　　 D. The quality for mountaineering
