I remember my mother as a strong woman. She came to America when she was 12—old enough to remember her language, she achieved scores and grades high enough to be admitted to Duke University. With a degree in computer science, she finally became the manager of a company in New York. My mother could give fluent speeches, say “wolves” correctly.

    It was my mother who always stressed the importance of language. From the time I was born, I was read to. I would fall asleep to the sounds of my parents' voices, whether it was my dad's softly accented, or my mother's clear English. The flow of language was unbroken, and whether in Chinese or English, the stream of communication flowed through our house.

    One October morning in sixth grade, after my mother had left to catch the train to the city, I left the house for the bus stop. I was surprised when I saw our car, the door hanging open. As I drew closer, I saw my mother lying on the ground.

    In the hospital, it was hard to believe that the lady who lay before me was my mom. My mother could not remember my name. As the leaves changed colors, it became clear that the stroke had created a wall between my mothers mind and mouth: her mind was not any less dear, but the words she spoke were not what she meant.

    The battle my mother faced taught me the importance of language. Without it, identity does not exist; relationships cannot be formed; stories cannot be told; directions cannot be given, and knowing anything about anyone is impossible. Without language, communication cannot take place. Without language, one cannot express the beauty of a sunset or the kindness of a stranger. The world would pass us by in silence.

    Natural selection is the process by which one type of animal within a species thrives because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth（灰蛾）is an example of the natural selection process.

    In 19th century England, certain types of peppered moths were able to better blend（融合）into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this process occurred comparatively quickly.

    At the beginning of the Industrial Age, most peppered moths in England were light-colored and covered with black markings, although a few moths had dark-colored wings. Because the light-colored moths blended into the light-colored bark on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks became covered with soot（烟煤）and became darker. The light-colored moths became easy for birds to see against the dark tree trunks. Since the dark-colored moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-colored to being mostly dark-colored.

    In the 20th century, the air cleared up, and the peppered moth population changed again. As tree trunks lighted due to less soot in the air, light-colored moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the coloration of the moths helped them to be “naturally selected” to survive.

Cara Jumper loves the giant saltwater pond on her grandparents Swansea, South Carolina, property(房产). One January afternoon, her grandfather Coy Jumper piled ten-year-old Cara and her sister, Claire, six, and Emma, five, into his Pontiac Sunfire and took them down to the pond. He and the girls walked happily through the pines, checking traps. No luck—they were empty.

    As the sun disappeared gradually toward the horizon, the group turned back to head home. But as Coy walked along the bank, he was suddenly unable to put one foot in front of the other. Then Cara saw Coy walk unsteadily and fall backward into the pond's deep water.

    When her grandfather didn't surface immediately, Cara jumped in. With one hand, Cara grabbed the bank. With the other, she reached for her grandfather, making contact in the dark water.

    Coy had suffered a stroke(中风) the year before. Now Cara wondered if he'd had one again. Just 80 pounds to her grandfather's 230, she held his head and pulled his face out of the water. That woke him, but he was still dead weight. She managed to move Coy towards the three-foot bank and pulled him up onto solid ground.

    The winter sun had almost disappeared, and they were all trembling. Cara knew she'd have to get Coy to the car, a quarter mile away. She helped him to his feet. Coy slowly moved forward.

    Sixty feet from the car, Coy fell. From there, he crawled, dragging himself under a gate, to the car. His granddaughters helped him into the passenger's side, and Cara got into the driver's seat.

"I used to sit on my dad's lap and drive," she says now. Coy, too, she says, had let the fifth grader drive through the fields around the house. Still, she felt nervous, but she pushed on the gas and steered(驾驶) them the three miles home. "I was trying to get there fast, but I didn't want to get us hurt," Cara says. When she pulled the Sunfire into the garage, her grandmother, Esca was there to meet them.

Coy spent six days in the hospital recovering from a stroke. Says Esca, "If Cara hadn't helped, she might not have a grandpa anymore."

    Arthur Miller(1915-2005) is universally recognized as one of the greatest dramatists（剧作家） of the 20^th century. Miller's father had moved to the USA from Austria-Hungary, drawn like so many others by the “Great American Dream”. However, he experienced severe financial hardship when his family business was ruined in the Great Depression (大萧条时期) of the early 1930s.

    Miller's most famous play, Death of a Salesman, is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as indicators (标志) of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with his system, Willy is “burnt out” and in the cruel world of business there is no room for sentiment (情绪): if he can't do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end.

    When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics' Circle Award, and the Pulitzer Prize for drama. It was the first play to win all the three of these major awards.

    Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005, the 56^th anniversary of the first performance of Death of a Salesman on Broadway.

    I owe my father a huge thank you! Sure, I need to thank him for all those years of paying my bills, fixing my bikes, and providing a shoulder to cry on. But this year I realized that his contributions to my childhood were much more than that.

    I grew up as Daddy's Little Girl. If I had a problem that needed fixing or a question that needed answering, he was the one I ran to. He helped me get through everything from math homework as a high school student to career choices as a young adult. He always expected that I do my best in whatever I did, and he believed I could succeed in anything I put my mind to. As a result, I learned to hold myself to those same standards. He always showed me unconditional love, which helped me learn to love myself. It was something I'd taken for granted until I realized from talking with my friends that they had no similar view of their self worth. Having fathers that didn't believe in them left them to grow up not believing in themselves.

    As I was growing up, my father also modeled how a woman should be lavished. He treated my mom with love and respect. As a result, I grew to expect nothing less than that from the men I dated and from the man I would eventually marry. Dad was a living picture of godliness (虔诚), honesty and responsibility. It was only recently that I realized what a deep effect fathers have on their daughters' lives. That is why I want to thank my dad for the godly example of love that he has been to me throughout my life.
