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.”

    Want to stay away from colds? Put on a happy face.

    Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from cold, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.

    “It seems that positive feelings may reduce the danger of illness,” said the study's chief researcher Sheldon Cohen.

    In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed positive feelings were also less likely to tell their doctors that they felt ill.

    In this study, Cohen's study interviewed 193 adults every day for two weeks. During the interviews, the people told researchers about the happy or sad feelings they had that day.

    After the two weeks, the people were given colds by doctors and had to stay alone in a room for six days.

    The result showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness was less serious and lasted for a shorter time.

    Cohen believes that when people experienced positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.

    The world's first luxury space hotel, Aurora Station, was announced Thursday at the Space 2.0 Summit in San Jose, California. Developed by US-based space technology start-up Orion Span, the space station will host six people at a time, including two crew members, for 12-day trips of space travel. It plans to welcome its first guests in 2022.

    "Our goal is to make space accessible to all," Frank Bunger, CEO and founder of Orion Span, said in a statement." Upon launch, Aurora Station goes into service immediately, bringing travelers into space quickly and at a lower price point than ever seen before."

    While a$10 million trip is outside the budget of most people's two-week vacations, Orion Span claims to offer an authentic astronaut experience. "It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months, at a fraction(小部分)of the cost," says Bunger. During their 12-day adventure, the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit, where they will witness incredible views of the blue planet. The hotel will orbit Earth every 90 minutes, which means guests will see around 16 sunrises and sunsets every 24 hours.

    Activities on board include taking part in research experiments such as growing food while in orbit, which guests can take home for a super-smug souvenir, and soaring over their hometown. Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and, upon(return to Earth will be greeted with a specially arranged hero's welcome. While enjoying the thrills of zero gravity, the travelers will be able to float freely through the hotel, taking in views of the northern and southern aurora from the station's windows.   Deposits are already being accepted for future stays on the space hotel.

    Christmas is a great time with family and friends. One of the best ways to bond with (团结)one another is through games. So why not play some great Christmas party games?

    Present pickup is a great game for both young and young at heart. It can be played inside or outside. To prepare for the game, you will need to have some small boxes and some small gift bags. This is a great way to use the paper from last year. There should be as many presents as players. You'll also need four or more candy canes(甘蔗). Two large boxes can be used to drop the presents in.

    Two ropes will be needed. Take one rope and make a starting line. The other rope will mark the finish line. Place the large boxes at the finish line. Equally divide the presents into two groups. It's best to have an equal number of boxes and bags on each side to make it fair.

    The first player on each team will take two candy canes. When it's time to start, they'll pick up the presents only using the candy canes. Each player must run his present to the box or finish line and drop it in. If it's dropped on the way, the player starts over. After they drop their presents, the players will run the candy canes to the next players. This continues until all the presents have been picked up. The first team to finish wins.

    To play kids against adults, you may want to put easier presents in a group for the kids and more difficult ones for the adults. There are many variations to the game, so have some fun and come up with your own.

    If you ever have the desire to break out into song—in the shower, in the car, maybe at your neighbor's karaoke night—you should embrace it whole-heartedly. This ancient art not only makes you feel good, it can also improve your well-being, reduce your feelings of pain, and even extend your life.

    Using your voice to sing, rather than simply carryout a conversation, offers unique benefits because singing affects our bodies. Also, studies link singing with a lower heart rate，decreased blood pressure and reduced stress according to Patricia Preston-Roberts, a music therapist. She uses song to help patients who suffer from a variety of problems.

    Singing, particularly in a group, seems to benefit the elderly particularly well. As part of a three-year study examining how singing affects the health of those fifty-five and older, a Senior Singers Chorus was formed by the Levine School of Music in Washington, D. C. The seniors involved in the chorus, as well as seniors in two separate arts groups about writing and painting, showed significant health improvements compared to those in the control groups (控制组).Obviously, the arts groups reported thirty fewer doctors' visits, fewer eyesight problems, less depression, and less need for medication.

    Even lead researcher Dr. Gene D. Cohen, director of the Center on Aging at George Washington University, was surprised at how big an effect the seniors' arts participation had on their health. Cohen said, “The average age of all the subjects was eighty. This is higher than life expectancy. So, if an effect were to be achieved, one would ordinarily expect to see less decline (下降) compared to the control group. The fact that there was so much improvement in many areas was the surprising factor." The seniors also noticed health improvements and they reported feeling better both in daily life and while singing.

    The part of the brain that works with speech is different from the part that processes music. “People seem to enjoy doing something jointly with other people. There are a lot of facts that being socially involved is good for people with dementia (老年痴呆).”Ballard said.

    The arts are showing up as a treatment tool in hospitals across the country. If you are thinking of volunteering, singing at a hospital may be a good choice—not only for the patients, but also for yourself.

    No one knows how much money Dr. Lyle Tullis gave away to students. I was his colleague for nearly a decade and I never stopped being amazed at his generosity. Our college has a program of providing cross-cultural experiences for students. Lots of students take advantage of summer experiences oversea. I discovered that no group left for overseas without some of its members receiving financial help from Dr. Tullis.

    It wasn't that he made a lot of money. For one thing, he taught in a church-run school. There, his salary (薪水) was half of what those people earned in a tax-supported school.

    Other colleagues occasionally complained about the low pay. Not Lyle Tullis. Occasionally some professors would leave our campus for a better-paid position. They told me they did so because, with better pay, they could provide for their families.

    The size of Lyle Tullis' paycheck never seemed to be the most important thing to him. I realized that one day when I was thanking him for helping a student, his eyes shone as he said to me, "I've got so much money that I don't know what to do with it. So, I just give it away."

    Most people wouldn't have thought that way. Dr. Tullis drove one of the oldest cars on campus. It was even older than almost any of the students' cars. His home, while comfortable, was not fancy at all. But Lyle Tullis lived with the feeling that he had so much money that he needed to give it away.

    He was one of the favorite on campus. Cynics (愤世嫉俗) might say he bought fame. But they would misunderstand. Lyle wanted to devote his life, all of it, to helping others.
