Dear Sam,

    I hear that you'll travel to China next month. Now I'll tell you anything about it. Beijing is capital city of China. There are so many amazed places we cannot miss. For example, the Great Wall -- one of the seven wonder in the world, the Palace Museum and Yuan Ming Yuan. And you may also go to Hua Shan -- a dangerously steep mountain. At last I advise you to visit Hu Nan, that is famous for Zhang Jia Jie. In the way, have you ever heard of Mao Zedong, one of the greatest leaders in Chinese history? If you go to Shao Shan, you'll know many about him. Oh, I must be stop now, but I will get ready for my final exams.

                                                                                                                                                                         Ahfang

    Fun doesn't have to be expensive

    Everyone likes to have fun, but not everyone has much money to spend. Here are some free or cheap ways to enjoy yourself.

    Go outside

    Going outside in good weather can be a lot of fun if you don't want to stay at home. {#blank#}1{#/blank#} If you live in a city, you can go window-shopping. Or you can explore an old part of town and admire the buildings.

    Try a hobby

    While you're out, take pictures of things you find. Planning and taking pictures can make you aware of the beauty all around you. Photographic equipment can be expensive, but it doesn't have to be. You probably already own a camera or a cell phone that can take pictures. Other creative hobbies can also be done with basic materials. {#blank#}2{#/blank#}

    Find an event

    Libraries often hold free public events. {#blank#}3{#/blank#}And while you're there, borrow a book or movie for free. Museums and universities also hold free events.

    If you can't find a free event, you can volunteer at an event that requires tickets. People who organize concerts and plays need help.{#blank#}4{#/blank#} Sometimes they reward volunteers with free tickets.

    Meet a friend

    Relationships are often the best things in life. {#blank#}5{#/blank#} For example, invite a friend for a walk, an event or a time working on your hobby. Hosting doesn't have to be difficult. If your friend comes in the afternoon, you don't have to serve a meal. You can sit and talk, play board games or card games or watch a movie together.

A. A friend in need is a friend indeed.

B. Stop by one to find out what's going on.

C. Hike or bicycle with a friend on a nearby path or in a park.

D. Whatever you do, find a friend to share it with.

E. It's a good idea to stay at home to watch a movie.

F. You can set up or take down chairs or greet visitors.

G. Drawing and writing require nothing more than a pencil and paper.

    A study of more than five million books, both fiction and non-fiction, has found a marked decline in the use of emotional words over time. The researchers form the University of Bristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise.

    They found that almost all of the categories (类别) showed a drop in these “mood words” over time. Only in the category of fear was there an increase in usage.

    “It is a steady and continuous decrease,” said Dr Alberto Acerbi. He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape. “One thing could be that in parallel to books the 20th century saw the start of other media. Maybe these media—movies, radio, drama—had more emotional content than books.”

    Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour：the ratio (比率) between the two varied greatly, apparently mirroring historical events.

    During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash. But the ratio plunged at the height of the Second World War. Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends. In the paper, they even argue that the reverse could be true.

“It has been suggested, for example, that it was the suppression (压抑) of desire in ordinary Elizabethan English life that increased demand for writing ‘filled with romance and sex' perhaps,” they conclude, “songs and books may not reflect the real population any more than catwalk models reflect the average body.”

     (Note：Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

    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.

    Your life is composed of all the little things we experience everyday, and knowing how to find joy in some of those little things is one of the easiest ways to let happiness slowly fill your cup. In order for that to happen, you need to do two very simple things, put yourself in such situations that you can experience happiness there, and then find a way to savour the experience and let it sink into you.

    To put yourself in the position of experiencing happiness every day, Lahan Catalino, Ph.D, at the University of California, San Francisco, recommends an approach called “prioritizing positivity”—organizing your day-to-day life on purpose so that it contains situations which naturally give rise to positive emotions. It involves both carving out time in your daily routine to do things that you really love and heavily weighing the positive emotional consequences of major life decisions, like taking a new job, and you will regularly find yourself.

    Then how can we find away to savour the happy experience and let it sink into you? Here is what psychologist Rick Hanson, the author of Buddha's Brain explains.

    Let a good fact become a good experience.

    Often we go through life and some good thing happens—a little thing like we checked off an item on our To Dc list, we survived another day at work, the flowers are blooming, and so forth. Hey, this is an opportunity to feel good. Don't leave the money lying on the table: recognize that this is an opportunity to let yourself truly feel good.

    Really enjoy this positive experience.

    Practice what any school teacher knows: if you want to help people learn something, make it as intense as possible—in this case, as felt in the body as possible—for as long as possible.

    When sinking into this experience, sense your intention that this experience is sinking into you.

    Sometimes people do this through visualization, like by sensing a golden light coming into themselves or a soothing balm inside themselves. You might imagine a jewel going into the treasure chest in your heart—or just know that this experience is sinking into you, becoming a resource you can take with you no matter where you go.

    It might seem a little cliche to say“stop and smell the roses”, but it's moments like those that can be stored in your happiness bank and withdrawn later. Living a happy life can be as simple as accepting the happiness that's already around you. If you want more, it's OK to go out and achieve it, but don't forget where happiness really comes from.

    After we all came to the conclusion that our family could responsibly care for dog; my husband and I started our search at a local animal shelter.

    We discovered a medium-sized male dog named Duke. This dog was a approximately only two years old and seemed to have the sweetest character. He looked at us through intelligent eyes and already knew how to fetch a ball. My husband and I immediately adopted him Duke quickly fit into our family's lifestyle. And he quickly learned the tricks like "sit", and "come".

But there was one skill that Duke could not seem to grasp—that of a watchdog. My husband was trying to teach him to remind us by giving a single warning bark when someone came into the yard. Duke would listen carefully to my husband's commands, but would cock （竖起）his head to one side in confusion and disappointment as if to tell his master that he just didn't understand what my husband was asking him to do. My husband would give his "watch" command. Duke would stand up—muscles tightened in readiness, but would not have a clue as to what he was in readiness for.

    One morning we heard the garbage collectors come up the driveway to get our garbage.

    My husband went to the open bedroom window so Duke could hear and see the men through the screen.

    "Watch" my husband commanded. Duke rose in readiness, looked at my husband as sudden comprehension dawned on him, gave a quick tail wave, and leaped through the window screen jumping happily out to greet the garbage men.

    Seeing that, I couldn't help laughing. My laughter did nothing for my husbands mood when he found what was happening and he just went away to repair the screen with no expression on his face.

    Duke brought our family so much fun. We never scolded or beat him. He was one of our family members.
