Most of you have heard of the term "big data"...

Most of you have heard of the term "big data" by now. When a company records the information of millions of users, it can analyze this "big data" to discover patterns and trends, allowing them to make better business decisions. It sounds like a science experiment, but every single user who gives up their information becomes an unwilling test subject. Companies claim that the data is used to provide "better service".

When shopping on Taobao, for example, you will get product recommendations based on your previous purchases, making it easier to finish a shopping list. However, did you really end up only purchasing items you originally had in mind? Or did you add a few more to the cart as a result of their recommendations?　　　　　　　 And the customer? They just become one more point of data in the system.

Of course, you might be fine with spending a little extra from time to time, but that is only a tiny droplet (水滴) in the vast sea of big data. Moreover, companies can actually buy and sell your data. So, that is another way for companies to make quick money. The next time a photo editing application asks for your contacts, location and calendar, you may wonder which company is looking to buy your information.

As technology grows more advanced, there will only be more opportunities for you to be exposed. Every single photo, text or video you post on the internet is there to help someone paint a better picture of you. Perhaps in the near future, someone will have collected enough data to predict the future decisions you will make before you even make them. Actually, given the amount of data that is already at their disposal (任意使用 ), maybe it is already happening.

1.What is the purpose of collecting big data for companies?

A.To cut the cost of running companies B.To assist companies get higher profit

C.To provide better service to customers D.To analyze companies’ economic advantages

2.What of the following is the missing sentence in Paragraph3？

A.Big date benefits the customers. B.That’s where the business wins.

C.Taobao dominates the shopping markets. D.Product recommendations make shopping easier.

3.What is the best title for the text?

A.More Data, Less Privacy B.Big Data, Better life

C.More Data, Less Trouble D.Big Data, Future Predictor

Many businesses offer membership cards to clients, promising that they will enjoy discounts, and the more they use the cards, the bigger the discounts will be. This is a common practice to attract and keep regular customers. By providing quality products or services at reasonable prices, businesses can indeed achieve this goal.

However, in recent years, consumers trying to book flights or hotels on certain websites have discovered that prices were actually higher for frequent users than for newcomers. They found that they could pay less by opening up a new account rather than using an old one. Unfortunately, these businesses are using information gathered through big data on clients’ preferences and purchasing habits to take advantage of them, which amounts to targeted price discrimination.

There have been numerous cases of overcharging based on big data on various shopping platforms in recent years. However, since it’s difficult to collect sufficient evidence to accuse these businesses, only a small number of consumers have chosen to take them on. Thus, big data, which is supposed to benefit the public, is helping some businesses cheat consumers. Big data itself is not a bad thing, since it is playing an increasingly important role in social life and economic growth. It can serve as a basic resource and tool. But since it is being used to overcharge frequent clients, the public has expressed anger. It’s a short-sighted behavior that will eventually drive away customers. Instead, big data should be used to improve businesses’ services and products by strengthening supervision(监督) and punishment so that this new technology can play its due role in Internet commerce.

It’s urgent to stop the misuse of big data by stepping up supervision. Market and network supervisory authorities need to join hands in this effort. The illegal use of big data should be severely punished. Advanced technology should be more widely used to supervise big data use.

It’s all right for businesses to employ certain methods to make big money, but to charge regular clients more than newcomers by taking advantage of information collected through big data analysis is violating regular clients’ rights as well as their trust in these businesses. The Law on the Protection of Consumer Rights and Interests clearly states that consumers have the right to know the truth about the commodities and services they buy. Thus, to overcharge regular clients is not only betraying the principle of fairness and sincerity, but also relevant laws. In the long run, it’s the businesses that will suffer most.

How Do We Make Good Use of Big Data in Commerce

Enough “meaningless drivel”. That’s the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data.

The House of Commons Science and Technology Committee’s report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard or kitemark (认证标记) to identify sites that have clear terms and conditions.

“The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone,” says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original.

It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. “we need to think through how we make that work in practice,” says Miller. Would we pay any more attention to a kitemark? “I think if you went and did the survey, people would like to think they would,” says Nigel Shadbolt at the University of Southampton, UK, who studies open data. “We do know people worry a lot about the inappropriate use of their information. But what would happen in practice is another matter,” he says.

Other organisations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. “We still don’t know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years’ time,” he says.

Shadbolt, who gave evidence to the committee, says the problem is that we don’t know how companies will use our data because their business models and uses of data are still evolving. Large collections of personal information have become valuable only recently, he says.

The shock and anger when a social media firm does something with data that people don’t expect, even if users have apparently permission, show that the current situation isn’t working. If properly administered, a kitemark on terms and conditions could help people know what exactly they are signing up to. Although they would still have to actually read them.

1.What does the phrase “meaningless drivel” in paragraphs 1 and 3 refer to?

A.Legal contracts that social media firms make people sign up to.

B.Warnings from the UK government against unsafe websites.

C.Guidelines on how to use social media websites properly.

D.Insignificant data collected by social media firms.

2.It can be inferred from the passage that Nigel Shadbolt doubts whether_______.

A.social media firms would conduct a survey on the kitemark scheme

B.people would pay as much attention to a kitemark as they think

C.a kitemark scheme would be workable on a nationwide scale

D.the kitemark would help companies develop their business models

3.Andrew Miller thinks social media needs more attention than banks mainly because_______.

A.their users consist largely of kids under 20 years old

B.the language in their contracts is usually harder to understand

C.the information they collected could become more valuable in future

D.it remains unknown how users’data will be taken advantage of

4.The writer advises users of social media to_______.

A.think carefully before posting anything onto such websites

B.read the terms and conditions even if there is a kitemark

C.take no further action if they can find a kitemark

D.avoid providing too much personal information

By now you’ve probably heard about the “you’re not special” speech, when English teacher David McCullough told graduating seniors at Wellesley High School: “Do not get the idea you’re anything special, because you’re not.” Mothers and fathers present at the ceremony — and a whole lot of other parents across the Internet — took issue with McCullough’s ego-puncturing words. But lost in the uproar was something we really should be taking to heart: our young people actually have no idea whether they’re particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it’s not just privileged high-school students: we all tend to view ourselves as above average.

Such inflated self-judgments have been found in study after study, and it’s often exactly when we’re least competent at a given task that we rate our performance most generously. In a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self-evaluations, while high-scoring students judged themselves much more stringently. Poor students, the authors note, “lack insight” into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with coauthor Justin Kruger, suffer from a “dual burden”: they’re not good at what they do, and their very ineptness prevents them from recognizing how bad they are.

In Dunning and Kruger’s study, subjects scoring at the bottom of the heap on tests of logic, grammar and humor “extremely overestimated” their talents. Although their test scores put them in the 12th percentile, they guessed they were in the 62nd. What these individuals lacked (in addition to clear logic, proper grammar and a sense of humor) was “metacognitive skill”: the capacity to monitor how well they’re performing. In the absence of that capacity, the subjects arrived at an overly hopeful view of their own abilities. There’s a paradox here, the authors note: “The skills that engender competence in a particular domain are often the very same skills necessary to evaluate competence in that domain.” In other words, to get better at judging how well we’re doing at an activity, we have to get better at the activity itself.

There are a couple of ways out of this double bind. First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don’t possess it, and compare what you can do against what truly excellent individuals are able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you’re doing, but just what it is that you’re doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.

If we adopt these strategies — and most importantly, teach them to our children — they won’t need parents, or a commencement（毕业典礼） speaker, to tell them that they’re special. They’ll already know that they are, or have a plan to get that way.

1.Which can be the best title of this passage?

A. Special or Not? Teach Kids To Figure It Out

高三英语阅读理解困难题查看答案及解析

My mum is about to have a spinal (脊柱的) operation. The operation is relatively minor, but does carry a risk of paralysis. Friends and family have reacted to this news by taking in such pessimistic terms that Mum has come to label this kind of talk as “psychological theft”. It occurs when other people increase your anxiety rather than provide comfort.

Last week Mum went to the post office and ran into Geoff who works for the local school. “How are you?” he asked. “Not great,” she replied. “I’ve been having some trouble with my back and I’m going to need an operation.” “Oh, the back is the most dangerous place to operate on!” he responded. “My mum had that and she was in terrible pain. Make sure you get all your affairs in order before you go under the knife—it takes months to get over it!” Geoff’s intention had been benign (美好的). He’d given his own mother’s story to show sympathy. However, Mum only heard pain, danger, knife, and months.

In the past few weeks, Mum’s mates and colleagues have told her stories about how their Auntie Trisha, who had just received an operation, was left speechless after hearing that she required a rapid follow-up operation; and how their neighbour, who had only a minor operation, never walked again.

It’s really not that difficult to think of alternative things they could have said that would be equally true, but more beneficial to bear. “The specialists in our hospitals are among the best in the world. It’s amazing what they can do these days!”—that’s a good one. “You’re going to feel much better afterwards.” —that’s another.

I’m not suggesting patients should be sheltered from the reality of the risks they’re taking. But if the decision to have an operation can’t really be avoided, what’s the purpose of underlining the drawbacks? It’s just common sense to say: “Get well soon, and how can I help?”

1.What does “psychological theft” in paragraph 1 refer to?

A.The negative comments. B.Psychological disorder.

C.The comforting words. D.Physical disability.

2.How might the author’s mum have felt after hearing what Geoff said?

A.Sympathetic. B.Relieved.

C.Grateful D.Worried.

3.How did the author explain his idea in the text?

A.By using examples. B.By analysing causes.

C.By following time order. D.By discussing research findings.

4.What lesson does the author want to teach us?

A.Treat patients with adoration.

B.Communicate more with other patients.

C.Be well-prepared for unavoidable operations.

D.Find an appropriate way to comfort patients.

If you have never ever heard of pawpaw，you are not alone. Most Americans do not know of the fruit，although it is native to the United States. Once，however，it was one of the most popular fruits in North America. Happily，those who love the pawpaw are trying to return it to its former position in American foods.

The pawpaw is a kind of fruit that grows on trees found all over the eastern United States. It is similar in size to a typical mango. It has a dull green-colored skin，and a soft，almost creamy orange inside. Most people agree that the pawpaw tastes like a combination of bananas，apricots （杏）and mangos. Most people are very surprised by its sweet taste. The fruit has a very short harvest season，from two to three weeks in September and October.

The pawpaw has never been sold commercially. The fruit requires a very special environment-low，wet areas that sometimes flood. In addition，the fruit is good to eat for only two to three days after harvesting. This makes it hard to sell anywhere distant from the pawpaw trees.

Planters are again growing pawpaw trees and harvesting the fruit. In several states farmers have organized “pawpaw festivals” to reintroduce the food to people.

Farmers are trying to grow different kinds of paw paws that will be easier to ship and sell commercially. Donna and Jim Davis are pawpaw farmers in Westminster，Maryland. They told National Public Radio that they purchased their pawpaw trees in the 1990s and now sell the fruit at farmer markets and online.

So, who knows? Maybe the pawpaw will show up soon at a market near you.

1.What is the pawpaw's most outstanding nature?

A. It grows on trees all over the US.

B. Its sour taste is like an apricot.

C. It looks like a combination of bananas and mangos.

D. It is very rich in sugar.

2.Why is it difficult for the pawpaw to become a big business?

A. It has to be sold far from the pawpaw tree.

B. It is difficult to harvest in the low and wet areas.

C. It is hard to keep its freshness for long.

D. It needs expensive transportation to the market.

3.What do farmers do to deal with the disadvantage of paw paws?

A. They advertise on National Public Radio.

B. They plant improved pawpaw trees.

C. They organize pawpaw festivals.

D. They sell the fruit at farmer markets.

4.Which of the following can be the best title for the text?

A. A forgotten American fruit is becoming popular again.

B. Fruit of pawpaw plays an important part in America.

C. Most people have hardly eaten fresh paw paws.

D. A traditional fruit has changed people's diet.

When you make a mistake，big or small，cherish it as it’s the most precious thing in the world.

Most of us feel bad when we make mistakes，beat ourselves up about it，feel like failures，and get mad at ourselves.

And that’s only natural：Most of us have been taught from a young age that mistakes are bad，and we should try to avoid mistakes.We’ve been scolded when we make mistakes—at home，school and work.Maybe not always，but probably enough times to make feeling bad about mistakes an unconscious reaction.

Yet without mistakes，we could not learn or grow.If you think about it that way，mistakes should be cherished and celebrated for being one of the most amazing things in the　 world：They　 make　 learning　 possible；they make growth　 and improvement possible.

By trial and error—trying things，making mistakes，and learning from those mistakes—we have figured out how to make electric lights，to paint the ceiling of the Sistine Chapel，and to fly.

Mistakes make walking possible for the smallest toddler，make speech possible，and make works of genius possible.

Think about how we learn：We don’t just consume information about something and instantly know it or know how to do it.You don’t just read about painting，or writing，or computer programming，or baking，or playing the piano，and know how to do them fight away.Instead，you get information about something，from reading or from another person or from observing usually...then you construct a model in your mind...then you test it out by trying it in the real world...then you make mistakes...then you revise the model based on the results of your real world experimentation...and repeat，making mistakes，learning from those mistakes，until you’ve pretty much learned how to do something.

That’s how we learn as babies and toddlers，and how we learn as adults.Mistakes are how we learn to do something new—because if you succeed in something，it’s probably something you already knew how to do.You haven’t really grown much from that success—at most it’s the last step on your journey，not the whole journey.Most of the journey is made up of mistakes，if it’s a good journey.

So if you value learning，if you value growing and improving，then you should value mistakes.They are amazing things that make a world of brilliance possible.

1.Why do most of us feel bad about making mistakes?

A．Because mistakes make us suffer a lot.

B．Because it’s a natural part in our life.

C．Because we’ve been taught so from a young age.

D．Because mistakes have ruined many people’s careers.

2.According to the passage，what is the right attitude to mistakes?

A．We should try to avoid making mistakes.

B．We should owe great inventions mainly to mistakes.

C．We should treat mistakes as good chances to learn.

D．We should make feeling bad about mistakes an unconscious reaction.

3.The underlined word “toddler” in Paragraph 6 probably means________.

A．a small child learning to walk

B．a kindergarten child learning to draw

C．a primary pupil learning to read

D．a school teenager learning to write

4.We can learn from the passage that________.

A．most of us can really grow from success

B．growing and improving are based on mistakes

C．we learn to make mistakes by trial and error

D．we read about something and know how to do it right away

5.The author wants to tell us________.

A．what you should do when meeting with difficulties

B．where you can find your mistakes

C．how you can avoid making mistakes

D．why you should celebrate your mistakes
