15．　　Recently, teenagers face many kinds of problems. Like many of them, I was once troubled with worries and dissatisfaction. Few people could understand my feelings. (1)      
　　"The problem with your generation is that you always expect to be happy," my mother once said. (2)       Shouldn't we try hard to achieve it?
　　But now I have noticed a change in my thinking. I gradually realize what my mother said was correct. Over these years, many studies have shown that we are crazy about happiness and high personal confidence. (3)       In fact, we may often be happier when we stop focusing on happiness.
　　We should also reset our expectations of the future. Don't expect miracles (奇迹), and accept that no matter how hard we try, feelings of failure and unhappiness will appear from time to time. When we feel sad, it's often because we have learned something painful but important. (4)       At the same time, we should learn how to deal with them better than trying to make them disappear.
　　(5)       As my mother tried to teach me all those years ago, "Prepare for the worst, hope for the best, and be unsurprised by everything in between."

16．　　In 2009. Todd Bol put up a Little Free Library with the used boards. That was to show his respect and love for his mother, who loved reading very much. The idea quickly spread, and Todd made a wise decision to set up Little Free library as a non-profit (非营利的) organization with signs that read "Little Free Library: Take a Book, Return a Book." Today there are about 100,000 little free libraries in over 100 countries and they have a great influence on people's life.
　　Studies have shown that books in the hands of children have a meaningful influence on improving literacy (识字). Little Free Library spreads the idea that literacy is of great importance and pushes people to learn and grow in their own literacy.
　　Little Free Library can greatly improve the relationship among neighbors and strangers, too. "Within just a few miles of me, there are many little libraries in folks' front yards, sharing the joy of reading with anyone who passes by. I just live in such a world where books, and the knowledge that comes with them, are highly valued." Catherine, an American woman, said, "I've even received a note of thanks from a gentleman named Esteban. He was especially thankful to have a "friend" on a cold night: 'Thank you for this wonderful gift of a book. It's an excellent friend on this cold and lonely night. I'll return one in its place as soon as I can!'"
　　If each building has such a library, we will soon have a society that spends less time on the phones and more on the pages of a book.

　　The sweetest memory of my childhood is about a round table. When I was still little, my whole family would get together on different traditional (1)             to have dinner. We kids would be sitting around or playing hide-and-seek under the table while the grown-ups were having a (2)            .
　　When I got a bit older, my aunt brought back her boyfriend and my grandma cheerfully (3)             another seat to the round table. It seemed a little more crowded, but we all felt much (4)             to each other. When I was twelve, my grandpa passed away. That made us (5)             sad. However, when the whole family got together once again, we (6)             agreed that his chair, his bowl and his chopsticks should remain the same, even though his seat was empty, we felt like that he had never left us.
　　We all have a table like this in (7)             homes. It is a sign of reunion of our family showing our feelings. (8)             the reason why we come together may be different, the feelings behind it are the same. Usually different cultures (9)             by us around the table. What's more, we express the love not only for our family, but also for a community, our nation and even the whole world.
　　The history of our nation has been the stories of looking for or running to the round table (10)             we belong to. The round table has been a symbol of the Chinese feelings. It was, it is and will always be.
