Do you have a spare room in your house? What about your driveway for your car?

    Both of these can help you make money. Many people who have financial difficulties are taking advantage of what's been called the 'sharing economy'.

    Perhaps the best-known example of a company in this field is Airbnb.{#blank#}1{#/blank#}It says it operates in 34,000 cities and it has 800,000 listings of rooms and apartments. They seem to have cornered the market!

    {#blank#}2{#/blank#}Just Park's founder, Anthony Eskinazi, says: "When I had the original idea, I spotted a driveway close to a sports stadium. It would have been so convenient if I could have just parked in that driveway rather than in a commercial car park." And he has a big clientele(客户): Around 200,000 people have advertised their spaces on the site, and he says around half a million drivers use it.  {#blank#}3{#/blank#}They let drivers share their cars with other passengers.

    {#blank#}4{#/blank#}A church near Kings Cross in central London has apparently made over 200,000 pounds by renting out space in its yard to travelers! But the sharing economy has its competitors. People who run things like traditional hotels, commercial car parks and taxi services are afraid of ending up losing money.{#blank#}5{#/blank#}Because this is a new business world, those rules are not there yet. How will renting out your driveway affect your neighbor?

A. Any driver knows how valuable a place to park is.

B. A British company is doing something with parking spaces.

C. There are other sites doing very similar things, like Uber and Lyft.

D. It offers travelers a global network of accommodations offered by locals

E. Another problem is that regulations for these new businesses are unclear.

F. The American web business allows you to rent out your spare room to holidaymakers.

G. Now that the sharing economy is gaining the support of the financial community, corporations start paying attention.

    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.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation. {#blank#}4{#/blank#}Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid.

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on.

    Home can be a great place for children to study. It's important to provide a workspace of their own where they can read books or just write a letter to their friends.

    Location (位置)

    {#blank#}2{#/blank#}Kitchen and dining room are not so well suited for regular study，since books and pens get in the way of the day­to­day uses of those areas. Set up a place where a child can settle in and leave papers and pens at hand without having to clear everything away each night. For a child that likes being alone，set aside a corner of his bedroom，but keep it separate from things like games，music and other hobbies not related to studying.

    Keeping Things in Order

    Parents should encourage their child to spread out，but to leave it neat and orderly when he isn't using his workspace. Ownership is very important for self­respect{#blank#}3{#/blank#}The workplace should be personal，but not another part of the playroom.

    {#blank#}4{#/blank#}

    Encourage the whole family to help build a supportive environment that children need for success in school. Give them a good example of how to deal with problems，how to manage time and get things done in the right way. {#blank#}5{#/blank#}Study will be more enjoyable and effective when supported by the whole family.

F．Setting up a space in a common area of your home can be a good idea for children.

G．A child who learns to organize his space will carry organization into every corner of his life.

    Why Is Recycling Important?

    When you throw things away, you might be very glad to do it. Unfortunately, that's not the end of the story. The things we throw away have to go somewhere－usually they go off to be buried underground in a landfill (垃圾填埋) or burnt in an incinerator (焚化炉). Landfills can be terribly polluting. They look awful, they smell terrible, they take up space that could be used for better things, and they sometimes create harmful soil and water pollution that can kill fish in our rivers and seas.

    One of the worst things about landfills is that they're wasting a huge amount of useful material. It takes a lot of energy and a lot of resources to make things, and when we throw those things in a landfill, at the end of their lives, we're also saying goodbye to all the energy and resources instead of burying it in landfills. That certainly has advantages: it reduces the amount of waste that has to be buried and we can get useful energy from it. But it can also produce harmful air pollution, and burning almost anything adds to the problem of global warming and climate change.

    The trouble is, we're all in the habit of throwing things away. In the early part of 20^th century, people used materials much more wisely－especially in World War Ⅱ, but in recent decades we've become a throwaway society. We tend to buy new things instead of getting old ones repaired. A lot of men use single-use razors (剃须刀), for example, instead of buying reusable ones, while a lot of women wear single-use stockings. Partly this is to do with the great convenience of throwaway items. It's also because they're cheap. But wasteful period in our history is coming to an end.

    We're finally starting to realize that our lifestyle is creating problems for future generations. Earth is soon going to be running on empty if we carry on as we are. Americans have a much richer life than almost anyone else on Earth. What happens when people in developing countries such as India and China decide they want to live the same way as us? According to the environmentalists, we'd need two Earths to satisfy all their needs.

Social Phobia

    It is natural to feel nervous, or shy in front of others at times. Most people manage to get through these moments when they need to. {#blank#}1{#/blank#} It's probably more than shyness. It may build up into a powerful fear. As a result, people feel uncomfortable participating in everyday social activities. This is called social phobia (also called social anxiety).

    {#blank#}2{#/blank#} It prevents them from chatting with friends in the lunch time, joining an after-school club, or going to a party. Sometimes, they even feel too nervous to ask a question in class or go to a teacher for help. Social phobia not only prevents people from trying new things. It also prevents them from making the normal, everyday mistakes that may help people improve their skills even further

    It is really sad, isn't it? But the good news is that people with social phobia can learn to manage fear, develop confidence and communicating skills and stop avoiding things that make them nervous. Of course it's not always easy. Dealing with social phobia takes the willingness patience and courage to face fears. {#blank#}3{#/blank#}

    Therapists (治疗师) can help people create a plan for facing social fears and build the skills and confidence to overcome it. And family or friends are especially important for them. {#blank#}4{#/blank#}They can encourage them to pick a small goal to aim for, remind them to go for it, and be there when they might feel discouraged.

    Little by little, someone who decides to deal with extreme shyness can learn to be more comfortable. {#blank#}5{#/blank#} As shyness and fears begin to melt, confidence and positive feelings build. Pretty soon, the person is thinking less about what might feel uncomfortable and more about what might be fun.

A. Friends can overcome their fears easily.

B. But for someone, the anxiety can be extreme.

C. They are not able to make eye contact with classmates.

D. Social phobia makes people lonely or disappointed over missed opportunities.

E. Each small step forward helps build enough confidence to take the next small step.

F. It also takes an action to go forward rather than back away when feeling shy.

G. The support from those key people helps them gather the courage to try something new.
