Harper Lee, whose 1961 novel To Kill a Mockingbird on the racial troubles of the American deep south, has died at the age of 89.

    Until last year, Lee had been something of a one-book literary legend. To kill a Mockingbird sold more than 40 million copies around the world and earned her a Pulitzer prize, remaining a towering presence in American literature. Another novel, Go Set A Watchman, was controversially published in July 2015 as a “sequel” to Mockingbird, though it was later confirmed to be Mockingbird's first draft.

    But from the moment Mockingbird was published to almost instant success, the author consistently avoided public attention. Lee had lived for several years in a nursing home near the house in which she had grown up in Monroeville, Alabama—the setting for Maycomb of her famous book. Her neighbor for 40 years, Sue Sellers, said, “She was such a private person. All she wanted was privacy, but she didn't get much. There was always somebody following her around.”

    James Naughtie, BBC Books Editor, commented on the novels of Harper Lee: “I think she stands, particularly among American readers, as someone who shone a light into a very dark place. She was writing at a time when people were beginning to lift the lid on everything in the South which they'd chosen not to understand. That all changed in the 1960s. So I think her status for writing that book in its extraordinarily direct way will remain.

    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.

    While it may seem like everyone surfs the web these days, there is fine line between casually checking your social media pages and having a full blown Internet addiction. If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction. {#blank#}1{#/blank#}

Admit you are at risk of an addiction.

    More and more people in the world are becoming addicted to the Internet. You are not the only one with this problem; it is becoming more and more common and more and more well known. {#blank#}2{#/blank#}.

Set aside limited time for computer use.

    Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it; {#blank#}3{#/blank#} If you have a desktop PC, try not to go near it or put something over it like a sheet.

Call people instead of sending instant messages or texts.

    If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer. {#blank#}4{#/blank#}

Use an alarm clock or timer.

    Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your desktop. {#blank#}5{#/blank#}.

A. Make a small list of what you want to do within that time.

B. When the computer is not looking at you, you are less likely to use it.

C. This can be programmed to shutdown your computer after the set time

D. Luckily, there are ways to avoid living your life in front of the computer.

E. This will stop you from using the Internet so often or going on to another page.

F. If you have a problem on weekdays, phone your friends or ask for help in person.

G. Do not be embarrassed; find others with the same problem and help each other beat it.

    You've flown halfway around the world; you've sniffed out this place that nobody in Falongland or Thailand seems to have ever heard of; so what on earth is there to do here? You consider this question as you sink into an old wooden beach chair that holds you above the sand.

    It was a long journey from Bangkok to Huaplee. By the time you found the bus station and got yourself sorted out, it took almost as long as the flight from Falongland.

    Huaplee is located just south of Hua Hin, about two hundred kilometres from Bangkok, down the west side of the Gulf of Thailand. Not many tourists find this place，and the ones that do wonder if finding it has been their purpose all along.

    There's an apparent laziness that surrounds you here. It's what this place offers, and it，s free of charge. The small waves that tap the shoreline seem to slow everything down. You settle into your beach chair in preparation for a long rest. You sit there and watch the sea.

It's early afternoon, so the cook comes out and asks what you'd like to eat this evening. Before long he's rushed off to the market to buy the ingredients for whatever it was that you ordered—every meal fresh and to order. No menu here.

    There is no poolside noise here but just that wonderfully warm, clear blue sea. There⁹ s no street noise. The only sounds are the murmurs of nature.For now you just count your blessings (福祉)，listing them in the sand with your toe (脚趾)• You don't have to worry about being late for work. You don't have to do anything.

    The beach to your right stretches off to the horizon (地平线)，slowly narrowing to nothingness only to re-emerge again on your left, now steadily widening until it covers the chair beneath you. Sand to your left and sand to your right; it's unbroken, endless. No start, no end, just sand, sun,and peace. Step off it, and you re-enter the world of traffic, stress, work，and hurry.

    Normally you，re the type who can，t sit still for more than ten minutes, but you're on Huaplee Lazy Beach now and, in the right frame of mind, it stretches all the way around theworld.

     “How could it take me so long to find it?” you wonder.

    The fence was long and high. He put the brush into the whitewash and moved it along the top of the fence. He repeated the operation. He felt he could not continue and sat down.

    He knew that his friends would arrive soon with all kinds of interesting plans for the day.

    They would walk past him and laugh. They would make jokes about his having to work on a beautiful summer Saturday. The thought burned him like fire.

    He put his hand into his pockets and took out all that he owned. Perhaps he could find some way to pay someone to do the whitewashing for him. But there was nothing of value in his pockets—nothing that could buy even half an hour of freedom. So he put the bits of toys back into his pockets and gave up the idea.

    At this dark and hopeless moment, a wonderful idea came to him. It filled his mind with a great, bright light. Calmly he picked up the brush and started again to whitewash.

    While Tom was working, Ben Rogers appeared. Ben was eating an apple as he walked along the street. As he walked along it, he was making noises like the sound of a riverboat. First he shouted loudly, like a boat captain. Then he said “Ding－Dong－Dong”,“Ding－Dong－Dong” again and again, like the bell of a riverboat. And he made other strange noises. When he came close to Tom, he stopped.

    Tom went on whitewashing. He did not look at Ben. Ben stared a moment and then said: “Hello! I'm going swimming, but you can't go, can you？”

    No answer. Tom moved his brush carefully along the fence and looked at the result with the eye of an artist. Ben came nearer. Tom's mouth watered for the apple, but he kept on working.

    Ben said, “Hello, old fellow, you've got to work, hey？”

    Tom turned suddenly and said, “Why, it's you, Ben! I wasn't noticing.”

     “Say—I'm going swimming. Don't you wish you could? But of course you'd rather work—wouldn't you? Of course you would.”

    Tom looked at the boy a bit, and said, “What do you call work？”

     “Why, isn't that work？”

    Tom went back to his whitewashing, and answered carelessly.

     “Well, maybe it is, and maybe it isn't. All I know is, it suits Tom Sawyer.”

     “Oh come, now, you don't mean to say that you like it？”

    The brush continued to move.

     “Like it? Well, I don't see why I shouldn't like it. Does a boy get a chance to whitewash a fence every day？”

    Ben stopped eating his apple. Tom moved his brush back and forth, stepped back to look at the result, added a touch here and there, and stepped back again. Ben watched every move and got more and more interested. Soon he said，“Say, Tom, let me whitewash a little.”

    Tom thought for a moment, and was about to agree, but he changed his mind.

     “No—no—it won't do, Ben. You see, Aunt Polly wants this fence to be perfect. It has got to be done very carefully. I don't think there is one boy in a thousand, maybe two thousand, that can do it well enough.”

     “No—is that so? Oh come, now—let me just try. Only just a little.”

“Ben, I'd like to, but if it isn't done right, I'm afraid Aunt Polly ”

     “Oh, I'll be careful. Now let me try. Say—I'll give you the core of my apple.”

     “Well, here—No, Ben, now don't. I'm afraid …”

     “I'll give you all of it.”

    Tom gave up the brush with unwillingness on his face, but joy in his heart. And while Ben worked at the fence in the hot sun, Tom sat under a tree, eating the apple, and planning how to get more help. There were enough boys. Each one came to laugh, but remained to whitewash. By the time Ben was tired, Tom sold the next chance to Billy for a kite; and when Billy was tired, Johnny bought it for a dead rat—and so on, hour after hour. And when the middle of the afternoon came, Tom had won many treasures.

    And he had not worked. He had had a nice idle time all the time, with plenty of company, and the fence had been whitewashed three times. If he hadn't run out of whitewash, Tom would have owned everything belonging to his friends.

    He had discovered a great law of human action, namely, that in order to make a man or a boy want a thing, it is only necessary to make the thing difficult to get.
