Alexis, 17, sat quietly in the passenger seat of her dad's car. She let her eyes lazily scan the landscape for wildlife. Then a deer came into view about 200 yards in front of them. “Dad, there's a deer there!” Alexis said. It was a male deer with sharp antlers (角) on each side of its head.

    As the car moved closer, Alexis saw that the deer's head was bent toward the ground. Then she heard a scream and saw an arm fly up near the deer's head. Alexis realized the deer was attacking a woman. Sue, a 44-year-old mother, had been out for her morning run. The deer followed her and edged closer. “I knew I was in trouble.” Sue says. She went to pick up a stick for self-defense, and the deer charged. It lifted her with its antlers and threw her into the air. Sue could feel blood flew down her leg. Within seconds, the deer had pushed her off the road.

    When Alexis and her father pulled up, the deer was throwing Sue like a doll. Alexis looked into the woman's terrified eyes, and before her father had even stopped the car, the teenager jumped quickly out of the car and ran toward the deer. “I was kicking it to get its attention." she says. Then her father, who had followed his daughter, pushed the deer away from the women.

    Alexis helped Sue into the car and then applied a piece of cloth to Sue's injured leg. “We're going to get you to a hospital.” Alexis said. Then she heard her father shout loudly. He had been knocked to the ground. Alexis took hold of a hammer from the car and ran to where her father lay on his back. She beat the deer's head and neck, but the blows didn't scare it away. “I was losing faith.” she says. “A couple more strikes. Alexis.” said her father. “You can do it.”

    Turning the hammer around, Alexis closed her eyes and beat the deer's neck with all her strength. When she opened her eyes, the deer was running away.

    Alexis got in the driver's seat and sped toward the nearest hospital. After Sue was treated, she tearfully thanked her rescuers. “You expect a teenage girl to get on the phone and call for help,” she says, “not to beat up a deer.”

    Colorado officials will stick to a plan to kill some mountain lions and bears to support the state's dropping mule deer (长耳鹿) population.

    Wednesday's vote permits organizations to kill up to 25 black bears and 15 mountain lions per year in the central and western parts of the state. The project will run for three years, to be followed by a six-year study of how deer populations respond to fewer predators(捕食者).

    The population of Colorado's mule deer has suffered a puzzling, years-long drop to about 450,000, which state officials said was about 110,000 fewer than there should be. A 2014 state study tied it to seven causes, including predators, whose number has greatly increased in recent years.

    Some experts, however, said the state should focus first on the human-led destruction(破坏) of mule deer habitat(栖息地). “The drop of the mule deer population is obviously not a simple problem with simple causes,” Brian Kurzel, director of the National Wildlife Federation, said. “By far, the greatest problem—the one that I think deserves the most attention in any science-based study—is habitat quantity and quality.”

    Kurzel pointed out that the U.S Bureau of Land Management recently agreed to create 15,000 new oil and gas wells somewhere in western Cororado, which was often called “the mule-deer factory”. There, the number of mule deer has fallen to about 30,000 from more than 100,000 in the early 1980s. Though state officials have known oil and gas development affects the population of mule deer, they didn't go against the plan.

    Other causes like building highways, population growth and human activities are also curbing the mule deer population, according to the study.

    State Parks and Wildlife officials don't necessarily disagree. They started a $4.5 million program as a way to gather research for later decisions.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home still hasn't sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $ 15,000 to $ 20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares to others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    The number of giraffes is becoming smaller across Africa, according to the Giraffe Conservation Foundation. The total population has dropped by 40 percent in the last 15 years. Surprisingly, even scientists haven't given much attention to giraffes. We are learning more about their ecology, but what we know is still way behind what we know about other species. "It's a silent extinction," said Dr. Julian Hennessy, a wildlife scientist.

    "The main reason for the smaller number of giraffes is their loss of living places," said Hennessy, "as an increasing part of land is used for farming. But hunting also has a big influence." You might wonder why hunters would focus on giraffes. First of all, once a giraffe is brought down, there is lots of meat with a small amount of effort. Besides, there is another thing encouraging the hunting. In Tanzania, Hennessy says, the latest word on the street is that eating giraffe meat could cure AIDS. Fresh giraffe heads and bones can be sold at prices of up to $140 per piece.

    Another widespread misconception about giraffes is that they are everywhere. Look at kids' books which are full of giraffes. They are always in zoo collections. They can be seen easily, so you don't think we have to worry about them. But the truth is that they are in danger of extinction. There is a lack of right and true data.

    Hennessy and other researchers are now pulling together the data needed to improve the situation of the entire giraffe species and all nine subspecies (亚种). The information will be used to change the giraffe's listing on the International Union for Conservation of Nature Red List, which now lists the species as of "least concern" but two subspecies as "endangered". "It's a lot of work to gather the necessary information," Hennessy says. "And several other giraffe subspecies will be recommended for endangered listings next year or the year after." He hopes that the world will finally start to take notice of how endangered these beloved animals have become.

    Black Friday

    The day after Thanksgiving is the start of the holiday shopping season. Thanksgiving is always on a Thursday, so the day after is a Friday. This day has come to be known as Black Friday. It has been the busiest shopping day of the year since 2005.

    Most stores offer great deals on Black Friday. They open their doors in the small hours of the morning. They try to attract shoppers with big discounts. Some items like TVs are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

    Black Friday is a great time to get good deals. The problem is that there are not enough low-priced items to go around. Each store may only have a few. These items are in high demand. People stand in long lines to get such great deals. They may line up hours before a store opens. They may be hoping to get a low price on a TV or laptop, but not everyone who wants one will get one. Some people leave disappointed.

    The situation can be tense(紧张的). Some Black Friday events have been violent. Large, eager crowds have trampled(践踏) workers. Fights have broken out over toys or people cutting in line. People have shot one another over parking spots. But most Black Friday events are safe and fun. Still, if you plan on going, expect large crowds and a bit of pushing and shoving.

    So where does the name "Black Friday" come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it drew. In the 1960s, spread across the country. It seems that it is here to stay.

    Now people all over the country take part in the event known as Black Friday. It is even spreading to other parts of the world. Stores have held Black Friday events in the U.K., Australia, and Brazil since 2012. In Costa Rica Black Friday is known as "Viernes Negro." And in Mexico, stores offer an annual weekend of discounts. They call it "El Buen Fin," which means "the good weekend" in Spanish. I guess the language of savings is universal.

    Family fights are never pleasant. Whether you are dealing with a loud sister or a stubborn mom or dad, the situation can be bad. At least that's what we have learned to expect.

    What if it could be different? What if family fights and conflicts could be turned into opportunities to become closer? What if problems could be solved with everyone walking away feeling more deeply cared for and loved?

    Family fighting is, on one level, about power. Someone is telling someone else what to do. In a short moment, emotions can be brought out and the fight is on. You can go down that old road or you can try something different.

    In any fight, you have a need to be listened to and understood. People raise their voices and shout at each other because they're not being listened to. It's totally unconscious. You want your mom or dad to listen and understand. But you always seems to forget the person you're fighting with has the same need to be listened to. So if you can put aside your need for a few minutes, the situation will change quickly. Give the other person some time to express his or her feelings, and you will earn your turn to be listened to.

    And while you are listening, you have to listen for the right information. The best way to do this in emotional situations is to forget most of the words because many people can't express what they are feeling with words alone, especially when they are upset.

    But if the situation starts to get out of hand, it would be wise to just calm down and leave the problem until later because many fights happen at the wrong time. The situation will die down quickly, usually in less than 30 seconds. You can either move on to problem solving or reach an agreement to work on it at a better time.

    This way, everyone will feel respected and listened to, even when there is conflict. Emotions will be understood and respected, and it will bring your family closer together.
