    Nowadays,human-polar bear conflict is on the rise. 1. Last year,there were 21 conflicts in the village of Ittoqqortoormiit,Greenland,alone. 2.,as the changing climate reduces polar bears’ sea-ice habitat(栖息地)，and as humans take advantage of that ice loss in pursuit of economic opportunity.

Governments and industry leaders in Arctic countries must take responsibility and support ways for their citizens and employees to live and work safely together with potentially dangerous animals like polar bears,whose population will decrease by more than 30%by 2050 due to sea-ice habitat loss.

People living and working in the region need education,training and the necessary tools to protect themselves when faced with a polar bear. 3.Patrolmen help to safely scare away bears that may wander into their streets,using bright lights,loud noises,and etc.

4.; it’s also important to keep wildlife safe.There’s more to be done on national level.The five states with polar bear populations should keep their promise to work together on a 10-year plan to manage all aspects of polar-bear protection.

5.By actively supporting the shift to a low-carbon economy,and by reducing our own greenhouse gas missions,we common people are each helping protect the sea-ice habitat that polar bears and other marine mammals all depend on.

A.This will further increase

B.Ordinary people also have a role to play

C.But it’s not just about protecting human life

D.For example,polar bear patrols(巡逻队)have been set up in Greenland

E.Polar bears use the sea ice as a platform to hunt for seals,their main source of food

F.For example,9 human-polar bear conflicts were reported in all of Greenland in 2007

G.Governments need to make a more serious effort to assist Arctic communities with safe and clean waste disposal

    The three phases of life are increasingly a thing of the past.Where once working lives fitted neatly into the model of education,employment and then retirement,the simplicity of that division is being challenged by changing standards of the workforce.

Increasing numbers of workers,nearing their long-imagined transition(过渡)into retirement,seem to be actively putting off the moment at which they down tools.Newly released figures from the Office for National Statistics(ONS)have shown that there are over a million more over 50s in part-time work than a decade ago.And with nine out of 10 employers reporting difficulties hiring workers,there’s likely to be a growing market for their talents as bosses extend their searches to older people,including those who are willing to take on part-time responsibilities.

The ending of the three phases of working life isn’t simply down to people living longer or financial necessity-though those are certainly important factors-but also to an increasing desire to maintain a purposeful life. One survey of British retirees over 50 found that 85 per cent of them felt they’d retired too young—stopping working had left a void that they regretted afterwards.

The 2015 film The Intern conveyed this human need to have value.In it,Robert De Niro plays a 70-year-old widower who finds himself a fish out of water when he joins a trendy internet start-up.In the end,not only does he find the sense of belonging that he desires but his colleagues come to rely on his experience and different perspective.It’s a plot we can increasingly expect to happen in real-life offices over the decades to come as people live ever longer.

Already,we are seeing people in their 50s and 60s looking ahead to a retirement lasting 30 years,choosing instead to build second careers that they can maintain into their 70s or beyond. Freed from the financial burden of young children,they can prioritize flexibility,shorter working hours or more rewarding jobs in areas such as charity work or teaching.Many do it for no money at all,volunteering behind the till in charity shops or showing people round National Trust properties.

However,it’s the next generation where the effect of living longer will really be felt,and the financial necessity will start to bite.In the West,more than half of the children born in 2016 have a life expectancy of more than 100 years.In their book,The 100-Year Life,London Business School professors Lynda Gratton and Andrew Scott suggest that acquiring sufficient funds to see oneself through a 40-or 50-year retirement will likely be beyond all but the highest earners.

Then there’s the oft-repeated claim that young people today are the first generation to be poorer than their parents.Certainly property prices are changing the way they plan for the future. In the mid-Nineties,the average home cost less than three times the average wage;last year, ONS stats placed that ratio at eight times wages.

The overall effect of these trends is that young people recognize that they will likely have to postpone dreams of retirement and instead strap on(绑住)more debt spread over longer spans.It’s why 44 per cent of under 30s say they expect to be working well into their 70s and why data this year from the Bank of England show that 16 per cent of UK mortgages(按揭贷款)now have terms of 35 years or more-a figure that has tripled in the past decade.

All of these factors look set to contribute to a workforce that has a significantly wider range of ages in the future.In an ra of work when we’ve all learned to be more inclusive,only eight per cent of firms with a diversity programme have adapted it to go beyond gender,race and sexuality and into age.Incorporating older employees into the workforce is set to be the next big thing at the office.

If Robert De Niro has anything to teach us,it’s that this can be an enormous force permanently for both employees and businesses.

    City farms are gaining popularity in cities and towns around the United States.

Eco City Farms in Edmonston,Maryland,is located near shopping centers,car repair shops and homes.The neighborhood is a working-class community.People do not have very much money,and they have limited access to fresh food in markets.

Over the past two years,the farm has attracted volunteers from the community like Marcy Clark.She schools her four children at home.On a recent day she brought them to Eco City Farms for a lesson.Alston Clark thinks his experience very valuable.”I like coming out here.” he says,”You know,you connect with the earth,where your food comes from.You appreciate the food a little bit more.”

Margaret Morgan-Hubbard started Eco City Farms.She thinks of it as a place where people can learn to live healthier lives.”Growing food in a community and showing that you can have farms even in the city is helpful to strengthen the relationship in that community and brings people together, “she says. “Every piece of what we do here is a demonstration to show people everything about how to have a sustainable community. “From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees,but improving the soil with compost(堆肥)made from food waste.Sixteen wooden bins are filled with worms.Their job is to eat the food waste and help make it into compost.

Eco City Farms is an experimental operation.The farm gets its power not from the local electricity networks but from the sun with solar panels.In winter,the greenhouses are heated using a geothermal(地热的)system.

Vegetables can be grown all year.So once a week,all winter long,neighbors like Chris Moss and her three children bicycle to the farm to pick up a share of the harvest.

“I like eating the vegetables,”says five-year-old Owen Moss.

    Recalling their college days,friends Miguel Amaro,Ben Grech and Mariano Kostelec all say that their biggest problem was finding somewhere to live in the first place.

As an international student from Argentina,Mariano had to pay 12 months’ rent in advance to get his place in London.Dutchman Miguel booked some super-expensive residence in Nottingham because he didn’t know any better.Ben from the UK was looking around the streets of Nottingham knocking on doors trying to find a place.

A year after graduating from their own separate universities,the three men realized that there was a business opportunity.They came up with a plan to create an online marketplace matching students with accommodation(住处)。So in 2011 the three started work on their business and website Uniplaces.

They invested around E50,000.Later that year they won first round funding of 200,0000 euros led by the founder of UK property website Zoopla.

From there it was down to business,getting a permanent office in Lisbon,Portugal and persuading landlords(房东)to join the site and checking properties(房产)。The Uniplaces website was then officially launched in 2013,with an initial 50 properties in the Portuguese capital listed on the site.

Mariano,28,says,”We picked Lisbon as our first city as it totally made sense to stay here It is a low cost,good location with access to great talent such as good engineers,and people with excellent language skills,which is great when dealing with so many international students.”

Students using Uniplaces pay one month’s rent in advance via the website,and the sum goes through to the landlord 24 hours after they move in.I hereafter they pay directly to the landlord.Uniplaces takes a service fee of 20%-25%of the student’s first month’s rent

Since its launch,three million nights have been booked through the platform.which currently lists over 40,000 properties.The company has now employed 132 employees

Incomes grew four times in 2016 compared to the previous year.But it hasn’t been all smooth for the three entrepreneurs(创业者)。

1.What is the possible relationship among the three people?

A.Classmates.

B.Roommates.

C.Competitors.

D.Partners.

2.The website Uniplaces is intended to

C.evaluate properties for residents

D.find accommodation for students

3.Which of the following is most likely to be talked about after the last paragraph?
