Delighted as I was by the tomatoes in sight，my happiness deepened when I learned that Brown's Grove Farm is one of the suppliers for Jack Dusty，a newly opened restaurant at the Sarasota Ritz Carlton，where，luckily for me，I was planning to have dinner that very night.Without even seeing the menu，I knew I'd be ordering every tomato on it.( )1.What did the author think of her winter life in New York?A．Exciting.

D．They are juicy.【答案】1～3.BDBBAmazon 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 ecommerce 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 taxwise” and “having a huge antitrust(反垄断的) problem”．Will the President 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.( )4.In Amazon Go，people can________.A．buy products by paying cashB．buy carts without scanning a QR codeC．have no bother to check out and queueD．use an app to wait in a checkout line( )5.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.( )6.The reason why Donald Trump repeatedly criticized Amazon Go is that Amazon Go________.A．would result in a political crisisB．would threaten the career of cashiersC．may result in a huge antitrustD．is No.1 job killer in the list of criticisms( )7.The main purpose of writing the passage is________.A．to introduce the Amazon Go storeB．to explain how Amazon Go worksC．to arouse people's interest in AmazonD．to indicate Trump's attitude to Amazon【答案】1～3 BDB 4～7 CBCA 。
