Artificial intelligence (AI) is rushing into business. Firms of all types are using AI to forecast demand, hire workers and deal with customers. The McKinsey Global Institute, a think-tank within a consultancy, forecasts that just applying AI to marketing, sales and supply chains could create economic value of $2.7trn over the next 20 years.

    Such grand forecasts fuel anxiety as well as hope. Less familiar, but just as important, is how AI will transform the workplace.

    Start with the benefits.AI ought to improve productivity. Humanyze, a people analytics software provider, combines data from its badges（工牌）with employees' calendars and e-mails to work out, say, whether office layouts favour teamwork .Slack, a workplace messaging app, helps managers assess how quickly employees accomplish tasks. Companies will see when workers are not just dozing off but also misbehaving.

    Employees will gain, too. Thanks to advance in computer vision, AI can check that workers are wearing safety equipment and that no one has been harmed on the factory floor. Some will appreciate more feedback on their work and welcome a sense of how to do better.

    Machines can help ensure that pay rises and promotions go to those who deserve them. That starts with hiring. People often have biases but algorithms（算法）, if designed correctly, can be more unprejudiced. Software can flag patterns that people might miss.

    Yet AI^'s benefits will come with many potential drawbacks. Algorithms may not be free of the biases of their programmers, which can have unintended consequences. The length of a travel may predict whether an employee will quit a job, but this focus may harm poorer applicants. Older staff might work more slowly than younger ones and could risk losing their positions if all AI looks for is productivity. And surveillance（监控）may feel Orwellian—a sensitive matter now that people have begun to question how much Facebook and other tech giants know about their private lives.

    As regulators and employers weigh the pros and cons of AI in the workplace, three principles ought to guide its spread. First, data should be anonymized where possible. Microsoft, for example, has a product that shows individuals how they manage their time in the office, but gives managers information only in aggregated（整合）form. Second, the use of AI ought to be transparent. Employees should be told what technologies are being used in their workplaces and which data are being gathered. As a matter of routine, algorithms used by firms to hire, fire and promote should be tested for bias and unintended consequences. Last, countries should let individuals request their own data, whether they are ex-workers wishing to contest a dismissal or jobseekers hoping to demonstrate their ability to prospective employers.

    The march of Al into the workplace calls for trade-offs between privacy and performance. A fairer, more productive workforce is a prize worth having, but not if it chains employees. Striking a balance will require thought, a willingness for both employers and employees to adapt and a strong dose of humanity.

    We've all experienced peer pressure (同伴压力). It happens to everybody. However, people have different reactions. Confident people refuse to do things they don't want to do, but shy and anxious people often give in. It may be because they want to be liked. It may be because they worry that their friends will make fun of them, or perhaps they're just curious about trying something new. {#blank#}1{#/blank#}

    It's hard being the only one who says no and the question is：how do you do it? {#blank#}2{#/blank#}If you think that missing maths, or smoking, or going somewhere you know your parents wouldn't like is a bad idea then the answer is simple：don't do it. It's your decision, nobody else's. You don't need to be aggressive. You don't need to shout and scream, but you must be confident and you must be firm. You need to say, "No thanks. I don't want to do that."

    Being on your own against everybody else is very hard, so it can really help to have at least one other peer, or friend, who will say no too. {#blank#}3{#/blank#} You want friends who will support you when you're in trouble. You don't want people who will always agree with the majority. Remember, the most popular people aren't always the most trustworthy.

    {#blank#}4{#/blank#}  You can learn a lot from people your own age. They can teach you great football skills or the best way to do your maths homework. They can recommend music and advise you on fashion. And don't forget you can tell them things too, and that always feels great. So, find friends who have similar interests. And remember, friendship isn't about feeling depressed and guilty. {#blank#}5{#/blank#}

A. Choose your friends carefully.

B. Firstly, you must decide what you believe.

C. It's about sharing experiences and having fun.

D. Of course, peer pressure isn't completely bad.

E. It may be because they were all born to be stubborn.

F. Depression and guilt will surely give you peer pressure.

G. Whatever the reason, some people end up doing things they really don't want to.

    The number of speakers of English in Shakespeare's time is estimated(估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.

    In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.

    The main reason for the widespread demand for English is its present day importance as a world language. Besides serving the indefinite needs of its native speakers. English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West.

    The autumn wind woke me up from my dream. I took a deep breath and looked around. Suddenly I saw two people approaching me. As there was no one else in the park, they caught my attention immediately.

    The two people were getting closer and I heard them laughing. At first, this laugh made me annoyed as if they had broken my unity with this park and disturbed my thoughts. But all of a sudden, I noticed the age of them — they were old. I could not clearly identify their age, but the woman looked as old as my grandmother. She had grey hair, blue eyes, and a smile on her face. And all the time she was looking at HIM...

    "Jim, I think we should change the park. It's the same every Saturday. You know..." "Sus! Hug me."— that was all he said. He looked at her, smiled and gave her a hug.

    At this very moment, I saw an old but strong man who knew his wife, and no matter how often she could be complaining, he loved her! I imagined the many things they might go through together — so many hardships that might make them cry, all the problems that they might be experiencing right now and the probability that one of them would outlive the other. And the one that outlives will think the life they spent together was the most beautiful period of their life.

    They left, and I was sitting on my bench, shocked, and I had a special feeling in my heart. This feeling was hope! The old couple with all the complaints and tons of mistakes behind their backs made me realize that it was happiness that mattered in life. Eventually, all people would get old and die, and what made a difference was the person you had dedicated your life to. I made a wish — waking up one day, being old and feeling proud of being together with the person I loved to overcome all the obstacles ( 障碍) and fight for happiness.
