Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered(干预) with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man's interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.

    The Kaibab had a storybook forest of large-sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who have wandered through its forests and parks, have come to regard it as the most enchanting（迷人的）region it has ever been our privilege to visit. "This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.

    Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer's enemies. In 25 years' time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.

    The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd，but a far greater loss resulted from starvation and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.

    YOUR mom might cook a bowl of noodles for you on your birthday. But in the US, a mom makes a cupcake for her children on their birthday.

    Cupcakes are small, round cakes topped with frosting (糖霜). It has been an American tradition that moms bring cupcakes to the classroom to celebrate their child's birthday. But recently some doctors have called for this to be banned. They believe cupcakes contribute to child obesity. Despite their good intentions, however, some people believe that experts are interfering (妨碍) with American culture. The cupcake is seen as American as apple pie — only prettier.

    According to Marion Nestle, a professor of nutrition at New York University, the cupcake is the most democratic (民主的) of desserts. As they are small enough for one person, you don't have to share your cupcake with anyone — it's all yours. They are also all of the same size, so there can't be any cries of  “she got the bigger piece!”

    Each bite can taste different depending on how much icing you have. It is a lesson in self-determination. Some people eat only a little of the frosting every time, others have it all in just one bite.

    In recent years, eating a cupcake has become as trendy as having a cup of Starbucks coffee.

    Democratic presidential candidate Hillary Clinton jokingly promised on a talk show that if she was elected president, she would give everyone a cupcake on her birthday. Ruth Reichl, editor-in-chief of Gourmet magazine, explains that the rise of the cupcake is very much about going back to American national identity in food, which is all about comfort. “People want to think about when they and their country were innocent,” she said.

The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or so, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother” — the real mother or the mother-substitute(母亲替代物）.

During the first two weeks of its warmth is perhaps the most important psychological（心理的） thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes — one covered with cloth and one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother

    Why is cloth preferable to bare wire? Something that the Harlows called contact（接触的） comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't“rub”as well as does soft wire cloth. Prolonged（长时间的）“contact comfort” with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.

    According to the Harlows, the basic quality of a baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no matter how interesting they might be. It screams in terror and curls up into a fury little ball. If its cloth mother is now introduced into the playroom, the bay rushes to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. It then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace（拥抱）as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding on to its “mother.”

    You might think that “global warming” means nothing more than a rise in the world's temperature. But rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation, the citizens of Tuvalu will have to leave their homeland.

    During the 20th century, sea level rose 8~12 inches. As a result, Tuvalu has experienced lowland flooding of salt water that has polluted the country's drinking water.

    Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

    Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions (排放), which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years.” Laupepa told the BBC.

    Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.

    Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.

    The Boy Made It!

    One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn't have food, water, a phone, or other supplies. He was getting colder by the minute.

    Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use.

    He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn't, his body temperature would get very low, which could quickly kill him.

    Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.

    By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could he huddled (蜷缩) in his cave and slept.

    The next day, Nicholas went out to look for help, but he couldn't find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.

    Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls' survival show Man vs. Wild. That's where he learned the tips that saved his life. In each episode (一期节目) of Man vs. Wild, Grylls is abandoned in a wild area and has to find his way out.

    When Gxrylls heard about Nicholas' amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.
