[单选题]In a move that could revolutionize the way we buy groceries,Amazon opens its first supermarket without checkouts-human or self-service--to shoppers on Monday.Amazon Go,in Seattle,has been tested by staff for the past year.It uses hundreds of ceiling-mounted cameras and electronic sensors to identify each customer and track what items they select.Purchases are billed to customers'credit cards when they leave the store On entering the store,shoppers walk through gates,swiping their smartphones loaded with the Am-azon Go app.Then they are free to put anything into their own shopping bags.With the help of sensors on the shelves,items are added to customers'Amazon Go account as they pick them up-and delete any they put back.And an electronic receipt is issued as they exit The store opened to employees of the online retail giant in December 2016 and had been expected to allow the public in more quickly.But there were some teething problems with correctly identifying shoppers of similar body types--and children moving items to the wrong places on shelves,according to an Amazon insider.Gianna Puerini said the store had operated well during the test phase Hundreds of infra-red ceiling cameras have been trained over the last year to differentiate between customers as they move around the store,and between items for sale,even those with similar appearances.There are weight sensors on the shelves to help indicate if an item has been taken or put back And some items carry a visual dot code,like a bar code,to help cameras identify them.Amazon isnt offering any information on how accurate the system is.One thing we do know:they're on to the less-than-honest.A New York Times journalist had a go at shoplifting some cans of soft drink,but the system spotted it and put them on his bill Amazon has not said if it will be opening more Go stores,which are separate from the Whole Foods chain that it bought last year for$13.7bn（E10.7bn）.As yet the company has no plans to introduce the technology to the hundreds of Whole Foods stores.However,retailers know that the faster customers can make their purchases,the more likely they are to return.Making the dreaded supermarket queue a thing of the past will give any retailer a huge advantage over its competitors In its third quarter results in October,Amazon for the first time put a figure on the revenues generated by its physical stores:S 1.28bn.Yet almost all of that was generated by Whole Foods.While its stores may not yet be money spinners,analysts have said Amazon is using them to raise brand awareness and promote its Prime membership scheme.Brian Olsavsky,Amazon chief financial officer,recently hinted that rivals should expect more Amazon shops in the months and years ahead You will see more expansion from us-it's still early,so those plans will develop over time,he said in october

[单选题]In the digital age,we are forced to move quickly and expected to respond and get things done instantaneously.The rise in digital tools and platforms also aids in great distraction,and many people are left feeling paralyzed about how to be better,faster and Lip to date with everything they need to know in their work and personal lives.lt's exhausting.For anyone feeling the all-too-familiar procrastination and avoidance that comes from a world with too many choices and pressures,here are five tips to make sure you are keeping on top of everything and avoiding distraction in the digital age.1.Whether it's a Google doc,or something more robust like Workfront,there's no shame in needing a little help to get-and keep-yourself organized.Once you adopt a system,customize it to how you like to work,and stick with it.Just don't let it overwhelm you.If you can keep track of all your due dates and tasks in one place-rather than in your email,in a written notepad,on a whiteboard etc.-it's much easier to see the big picture and be able to prioritize.2.You can't climb a mountain in one giant leap,but you can climb it in a bunch of small steps.The same goes for getting things done.Break your tasks down into smaller chunks that are easier to accomplish.If something has been lingering on your list for a few days,figure out at least one thing you can do today to start.It helps you build momentum and-trust me-makes everything seem more attainable.3.Nothing is ever perfect.Believe me;I'm a perfectionist.I've tried.And honestly,there are some things that will never be done,You can'i keep tweaking the spacing on an ad forever.You can't change fonts on that document a million times.Don't get stuck if you feel like something isn't 100%.In many cases,98%will be just fine.Or even 95%.Ask for a second opinion if you want.but at some point,call it good enough,and move on.Your sanity will thank you,4.I can't tell you how many times I've arrived at work,looked at my to-do list and thought about how much l was going to accomplish that day.only to have it completely thrown out the window within the first 15 minutes,Things happen.A website goes offline.There's a PR crisis.The internet is down.You have to take a deep breath.prioriiize and acknowledge that some things are just not going to get done today,and you will have to pick it back up 10morrow.There's always tomorrow.5.Another perfectionist flaw:"I can do it all by myself!"You won't get very far if you are always irying to do everything by yourself and you don't allow others to help.It's hard to let things go;it really is.But it's a lot easier when you can trust someone else to handle it than to kill yourself staying until 10 p.m.every night.

[简答题]When we discuss the English language,we illuminate our weaknesses,prejudices and ambitions.Language creates communities,and some of these are solidarities of complainers and pedants.A statement about proper English is a statement not only about the language,but also about people-about who the proper English are,or just about who the proper users of English are.Typically,the celebrants and defenders of proper English are celebrating or defending something other than language.Where does our sense of the sproper'come from?In arguing about what is right and what wrong in any language,we appeal to authority.This authority is embodied in academies,the Ministry of Education（or its equivalent）and universities,as well as in the pronouncements of people who have appointed themselves authorities and have become known as such.We commonly accept these judges'pronouncements.There are also geographical criteria.These are evident in statements such as'Natives of Perugia speak the best Italian'or'People in Alsace have funny accents'.Typically,we feel that there are certain environments in which our language is decently used,and we favour the usage that obtains there.Sometimes,too,we defer to the example of a significant literary figure,saying that so-and-so is a model of correctness.A broader view is that'correct English is that which is used by the best writers',but who are they,and what are the criteria for their being so esteemed?The definition tends to be circular:the best writers are the ones who best use the resources of English.When we appeal to aesthetics,our arguments become vague.The aesthetically sensitive arbiter will argue that whatever is beautiful in language is good.（49）The problem here would seem to be that the desire for beautiful language concentrates on language as an object-on the sensory pleasure it affords rather than on what it signifies.Besides,as we know from our observation of others,the constant pursuit of beauty can be embarrassing.Alternatively,we may claim that the most elegant usage is that of the social elite.Perhaps this now seems an absurd position,but not long ago it would have been perfectly normal.The democratic option is to say that all doubtful matters should be decided by ballot,or just to say that the majority is right.We also appeal to logic.（50）Although there are discrepancies between logic and the ways we use language,we frequently use arguments from logic（or from what we imagine to be logic）in order to justify our choice of words or find fault with others'choices.In practice we tend to find our usual practices logical and anything else illogical.'Logic'is often a mask for arrogance and extreme patriotism.
