Population ageing refers to the situation in which the average age of the citizens of a country increases as a result of longer life expectancy（预期寿命）of its citizens or a reduction in the number of births every year.Today, both developed and developing countries around the world are experiencing an increase in the average age of its citizens with a growing proportion（比例）of elders in the population.

    An increase in the proportion of elderly persons in the population leads to a growing pool of volunteers.This has been considered as a global advantage where the elderly contribute free labor to community and government projects after retirement.These elders are more comfortable financially（财政上）and find pleasure in giving back to their communities and countries.Besides,older people are more experienced than younger people,and they can make use of their experience to help uphold morals（维护道德）and values in a country.

    What's more,an ageing population has something to do with fewer children.This can save much cost because less money has to be used to meet the needs of fewer children and young people in the economy.This would result in lower public education cost,lower health-care cost and other social programs that are provided for children by the government.

    However,there are also a lot of disadvantages.For example,an increase in the proportion of the elderly in the population raises questions as to how best to support them after retirement.Also older people are more likely to suffer from illnesses,so an increasing number of sick persons will put pressure on health care,which might not be able to meet the demand.

    Furthermore,an ageing population also increases competition for jobs,especially if the retirement age is extended（延长）.As older members of the population have a longer time to retire,young people will find it more difficult to find jobs.In this case,fewer innovations（创新）and changes take place in organizations because companies are limited to old ways of doing things.

    So,in order to solve these problems brought by an aging population,careful long-term strategic planning is required.The elderly are important and they have much to offer in helping the young people to understand their purpose in life.An increase in social enterprises（规划）should be the trend to help get the elderly involved in young people's lives.

    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.

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.

    What is your favourite colour? Do you like yellow, orange, red? {#blank#}1{#/blank#} Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead． You tend to be pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings.{#blank#}2{#/blank#} If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

    Most people have a list of wishes—things that they think will bring them happiness. Happiness lists are easy to come up with. However, the mechanism behind them is somewhat complicated, since it involves what psychologist Daniel Gilbert calls the greatest achievement of the human brain—the ability to imagine. To imagine what will bring joy to our future selves requires mental time travel, which is a unique human skill resulting from two million years of evolution. We use this skill every day, predicting our future emotions and then making decisions, whether big or small, according to our forecasts of how they'll make our future selves feel.

    Yet, our imagination often fails us. When we're lucky enough to get what we wished for, we discover that it doesn't come with everlasting happiness. And when the things we feared come to pass, we realize that they don't crush us after all. In dozens of studies, Gilbert has shown that we can mispredict emotional consequences of positive events, such as receiving gifts or winning football games, as much as negative events, like breaking up or losing an election. This impact bias(影响偏差) —overestimation of the intensity and duration of our emotional reactions to future events—is significant, because the prediction of the duration of our future emotions is what often shapes our decisions, including those concerning our happiness.

    Just as our immune systems work tirelessly to keep our bodies in good health, our psychological immune systems routinely employ an entire set of cognitive(认知) mechanisms in order to deal with life's habitual attack of less-than-pleasant circumstances. Actually, our psychological immune system has an impressive feature of its own: the ability to produce happiness. Thus, when life disappoints us, we "ignore, transform, and rearrange" information through a variety of creative strategies until the rough edges of negative effects have been dutifully dulled. When we fail to recognize this ability of our psychological immune systems to produce happiness, we're likely to make errors in our affective forecasting.

    Happiness, Gilbert points out, is a fast moving target. As passionate as we're about finding it, we routinely misforecast what will make us happy, and how long our joy will last. In reality, he adds that the best way to make an affective forecast is not to use your imagination, but your eyes. Namely, instead of trying to predict how happy you 'll be in a particular future, look closely at those who are already in the future that you're merely contemplating(冥想)and ask how happy they are. If something makes others happy, it'll likely make you happy as well.
