The life expectancy is the length of time that a person is normally likely to live. As it increases nowadays, the average person lives beyond the age of retirement. As a result, the elderly make up an ever-increasing percentage of society, which makes it more important to make effort to improve the lives of senior citizens.

    First of all, one way would be to make sure that the elderly have enough money on which to live. Obviously, when a person stops working, they still require a source of income to cover their basic needs such as food, accommodation and heating. A clear solution to the problem is for the government to make sure that the state pension(养老金) is enough for these needs.

    Measures should also be taken to overcome the health problems the elderly face. The government should also provide access to the best health care available, which may necessitate paying for residential homes where the elderly can have round-the-clock nursing, or, at least, providing medication free of charge to all people over a certain age.

    If we try to address the problem of social isolation (社交孤立), the lives of old people could be improved. If we organize trips for the elderly to community centers, visits from social workers, their problem of loneliness can be reduced a lot which marks the lives of so many old people living alone and far from their families.

    The last helpful suggestion is to change the attitude of the community towards its older members, who are all too often seen as a burden on society. We need to be taught from an early age to respect the views of old people, and appreciate their broader experience of life. This would help society as a whole, and encourage appreciation of the role that old people can still play today.

    Have you ever been sad because of failure? Please remember, for quite often achieving what you set out to do is not the most important thing.

    A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can't finish digging all the way through the earth, but look at what I've found during this period!”

    The boy's goal was far too difficult, but it did cause him to go on. And that is what a goal is for－to cause us to move in the direction we have chosen, in other words, to cause us to keep working!

    Not every goal will be fully achieved. Not every job will end up with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I've found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really makes sense.

    Construction on Knolly's Tunnel began in 1896, and it was opened on August 13th, 1898 by the man it was named after--Sir Clement C. Knolly, Acting Governor of Trinidad. It linked Rio Claro with Port of Spain. Its architecture is still admired and studied today, and many are amazed that Knolly's Tunnel has stood up to the earth's movement over so many years.

    Much research is being done on the tunnel. At the top of Knolly's Tunnel are cottages covered with leaves, where visitors can sit and enjoy the beauty of nature. Standing at the beginning of Knolly's Tunnel, you can see nothing but the tiny light at the end. The train tracks have been removed and replaced with small stones. Visitors can drive through the tunnel or walk through, but should do so in groups for safety. In the old days, there were no lights, but now there are street lights on the way to the tunnel, though not inside.

    On your way in, you may notice some manholes on the walls of the tunnel. These were there for individuals to step into for safety as the train passed. Knolly's Tunnel can be accessed through Tabaquite and through Mitchell Gap. The road was recently improved, but is better when you enter from Tabaquite, and there are signs on the road directing you to Knolly's Tunnel.

    On the drive to Knolly's Tunnel there are two other cottages where visitors can sit and just enjoy nature. At the site itself, there is nothing to purchase to eat or drink, but in Tabaquite there are several bars, a restaurant, and food outlets. A gas station and a health centre are also close by.

    For those who admire architecture, Knolly's Tunnel is a must-see when visiting Trinidad. For the nature lovers, there is no better place for them to be and for the historians, they can walk or drive through Knolly's Tunnel knowing that many of our ancestors toiled (worked hard) on its structure. So when you visit Trinidad, don't forget to take a look at Knolly's Tunnel!

    Sam, I say to myself as I start across the bridge, you must stop these thoughts and start thinking about what to do now that you have lost your falcon（猎鹰）, Frightful.

    Life, my friend Bando once said, is meeting problems and solving them whether you are an amoeba or a space traveler. I have a problem. I have to provide my younger sister Alice and myself with meat. Fish, nuts, and vegetables, are good and necessary, but they don't provide enough fuel for the hard physical work we do. Although we have venison（鹿肉） now, I can't always count on getting it. So far this year, our venison has been only road kill from in front of Mrs. Strawberry's farm.

    I decide to take the longest way home, down the flood plain of the West Branch of Delaware to Spilkill, my own name for a fast stream, that cascades down the south face of the mountain range I'm on. I need time to think. Perhaps Alice and I should be like the early Eskimos. We should walk, camp and hunt, and when the seasons change, walk on to new food sources. But I love my tree and my mountaintop.

    Another solution would be to become farmers, like the people of the Iroquois Confederacy who once lived here. They settled in villages and planted corn and squash（南瓜）, bush beans and berries. We already grow groundnuts in the damp soil and squash in the poor land. But the Iroquois also hunted game. I can't do that anymore

    I'm back where I started from.

    Slowly climb the Spillkill. As I hop from rock to rock beneath shady basswoods and hemlocks, I hear the cry of the red﹣tailed hawk who nests on the mountain crest. I am reminded of Frightful and my heart aches. I can almost hear her call my name, Cree, cree, car-ree.

    Maybe l can get her back if l beg the man who is in charge of the peregrines（游隼） university. "But it's the law," he would say. L could write to the president of the United states and ask him to make an exception of Alice and me. That won't work. The president swore to upload the constitution（宪法） and laws of the United States when he took office.

    I climbed on. I must stop thinking about the impossible and solve the problem of what to do now. I must find a new way to provide for us. Frightful is going to be in good hands at the university and she will have young.

    I smile at the thought of little Frightfuls and lift my reluctant feet.

    When I am fat above the river,1take of my clothes and moccasins（鹿皮鞋） and bathe in a deep, clear pool until I am refreshed and thinking more clearly. Climbing up the bank, I dress and sit down. I breath deeply of the mountain air and try to solve my problem more realistically.

    Three-day－old Oskar Lunde sleeps in a small bed at an Estonian(爱沙尼亚) hospital.

    Across the room, his father turns on a laptop computer. "Now we will register our child, "Andrei Lunde says as he lifts his identification card into the card reader. His wife, Olga, looks on. And just like that, Oskar is Estonia's newest citizen. No paper. No time spent standing in a line.

    Estonia has launched a project to make government administration completely digital. The goal is to reduce the size of the government work force, open up the decision-making process and fuel economic growth.

    Estonia has created a system that supports electronic authentication(身份验证) and digital signatures. It provides paperless communications for both the government and private industry.

    However, there are a few things that one cannot do electronically in Estonia: marry, end a marriage or buy and sell property. That is only because the government has decided it is very important to show up in person for some big life events. When Estonia declared independence from the former Soviet Union in 1991, it had to build a new economy. Government leaders looked for an industry where the country could compete. They decided on information technology and the Internet.

    When the poor country needed to replace a 1930s phone system, former President Toomas Hendrik Ilves rejected the offer of a free analog(模拟) system from Finland and argued for a digital one.

    Last year, information and communications made up 5.9 percent of the economy. The government hopes to increase that figure with an "e-residency" program that lets businessmen around the world register their businesses in Estonia, thus gaining a presence in the European Union. More than 51, 000 people from 167 countries have registered at a cost of only 100 euros, or＄114 each.

Socially, few things are more annoying than someone repeatedly checking their phone in the middle of your conversation with them. Soon enough, you're having unhappy thoughts, thinking of their way like, I'm boring you; you're more concerned with whoever's on that phone than me; you don't care about me. None of that is necessarily true, but this is: "If someone is engaged in a great conversation, they wouldn't care about their phones," says Leslie, a psychologist and researcher at NYU.

Do you sometimes wonder: What should I have said to a rude person like this? What if we have to talk to such maddening persons? Experts have advice about how to deal with this.

Whether you say something or not, remember that the cell-addict's annoying habits aren't about you. "It's rude, for sure, but sometimes we mistake the behavior for more than what it is," says Leslie. "It's possible that they are facing something tough and merely experiencing nervousness or anxiety," he adds. It's also possible that their partner is stuck with a flat tyre (轮胎) or their kid is sick in hospital. The point is that you don't know.

So before you become angry at the cell-addict's open rudeness, focus instead on building a better conversation than whatever's going down on Instagram. You might never be able to achieve this, given the power of today's social media, so if you're close enough to a person, Leslie advises you to directly ask them: "What's on that thing that's so interesting?" Chances are that they will apologise at once and quickly put the phone away. But if the answer is something real, talk about it. Better yet, you can avoid the situation in advance by saying something like, "I'm really interested in catching up properly, so how about we leave our phones in the car?" If they indeed have that flat tyre or sick kid, at least you won't have to assume that it's because your stories are boring.
