    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.

(1)、Which of the following has the closest meaning to the underlined word “thrives” in the first paragraph?
A、Reduces. B、Booms. C、Changes. D、Endangers.
(2)、What can we infer about the peppered moth's natural selection process?
A、The length of time was unusual. B、The soot levels in England did not affect it. C、This type of color change was typical for moths. D、It was a good example of environmental protection.
(3)、What's the difference between light-colored and dark-colored moths?
A、Dark-colored moths were originally easy to see on trees. B、Both kinds of moths preferred the dark-colored trees. C、Birds failed to see light-colored moths. D、The color of moths was unimportant.
(4)、Which would most likely happen if soot darkened England's trees again?
A、Birds would eat fewer moths. B、Moths would not be able to stay alive. C、Light-colored moths would disturb people's life. D、The population of dark-colored moths would increase.

    The fried foods, salty snacks and meat are major foods of the Western diet, which account for about 30 percent of heart attack risk across the world. Meanwhile, a diet rich in fruits and vegetables, the so called "Prudent" diet, can lower the risk of heart attack, according to a study.

    The research which looked at dietary habits in 52 countries, found people who ate a Western diet had a 35 percent greater risk of having a heart attack, compared to those who ate little or no fried foods and meat. Those who followed a "Prudent" diet had a 30 percent lower risk of heart attack, compared to those who eat little fruits and vegetables.

    The authors also looked at an "Oriental" diet, rich in tofu, soy and other sauces (酱类), and found it did not increase or decrease the risk of a heart attack.

    Previous studies have reached similar conclusions about the "Prudent" and Western diet in the United States and Europe, but did not include the Oriental pattern of eating. While some food of the Oriental diet may protect against heart trouble, the higher sodium (钠)content of sauces counter(抵消) that benefit.

    "This study indicates that the same relationships that are observed in Western countries exist in different regions of the world, "a professor of medicine at McMaster University said.

    Canadian researchers analyzed risk factors in food choices and the risk of heart attack in about 16, 000 people in 52 countries. Almost 6, 000 people had heart attacks, while the rest had no heart disease.

    Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well-known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half-dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else-there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

    What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. “In the sweat of the face shall you eat the bread.

    To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.

    I come from a large family of nine brothers and sisters, and all of us have kids of our own. On each Christmas night, our entire family gathers at my oldest sister's home, exchanging gifts, watching the nativity skit put on by the smaller children, eating, singing and enjoying a visit from Santa himself.

    The Christmas of 1988, my husband Bob and I had four children. Peter was eleven, Leigh-Ann was nine, Laura was six and Matthew was two. When Santa arrived, Matthew parked himself on Santa's lap and pretty much remained dazzled by him for the rest of the evening. Anyone who had their picture taken with Santa that Christmas also had their picture taken with little Matthew.

    Little did any of us know how precious those photos with Santa and Matthew would become. Five days after Christmas, our sweet little Matthew died in an accident at home. We were lucky to have strong support from our families and friends to help us through. I learned that the first year after a death is the hardest, as there are so many firsts to get through without your loved one. Birthdays and special occasions become sad, instead of joyous.

    When our first Christmas without Matthew approached, it was hard for me to get into the holiday spirit. Bob and I could hardly face putting up the decorations or shopping for special gifts for everyone. But we went through the motions for Peter, Leigh-Ann and Laura. Then, something extraordinary happened to raise our spirits when we didn't think it was possible.

    We were just finishing dinner when we heard a knock on the front door. When we went to answer it, no one was there. However, on the front porch was a card and gift. We opened the card and read that the gift-giver wanted to remain anonymous; he or she just wanted to help us get through a rough time by cheering us up.

    In the gift bag was a cassette of favorite Christmas music, which was in a little cardboard Christmas tree. The card described it as being "a cartridge in a pine tree," a twist on the "partridge in a pear tree" verse in the song, "The Twelve Days of Christmas." We thought that it was a very clever gift, and the thoughtfulness of our "elf"(精灵) touched our hearts. We put the cassette in our player and, song by song, the spirit of Christmas began to warm our hearts.

    That was the beginning of a series of gifts from the clever giver, one for each day until Christmas. Each gift followed the theme of "The Twelve Days of Christmas" in a creative way. The kids especially liked "seven swans a-swimming," which was a basket of swan-shaped soaps plus passes to the local swimming pool, giving the kids something to look forward to when the warm days of spring arrived. "Eight maids a-milking" included eight bottles of chocolate milk, eggnog and regular milk in glass bottles with paper faces, handmade aprons and caps. Every day was something very special. The "five golden rings" came one morning just in time for breakfast — five glazed doughnuts just waiting to be eaten.

    We would get calls from our family, neighbors and friends who would want to know what we had received that day. Together, we would chuckle at the ingenuity and marvel at the thoughtfulness as we enjoyed each surprise. We were so caught up in the excitement and curiosity of what would possibly come next, that our grief didn't have much of a chance to rob us of the spirit of Christmas. What our elf did was absolutely miraculous.

    Each year since then, as we decorate our Christmas tree, we place on it the decorations we received that Christmas while we play the song "The Twelve Days of Christmas." We give thanks for our elf who was, we finally realized, our very own Christmas angel. We never did find out who it was, although we have our suspicions. We actually prefer to keep it that way. It remains a wondrous and magical experience - as mysterious and blessed as the very first Christmas.
