Lions are the top tourist attraction to Kenya and also considered critically endangered. One of the main causes of their death is that people kill them in return for lions attacking their cows. “We put our cows in a small cow shelter at night,” locals said, “and that's when the trouble would start. Lions would jump in the shelter and kill the cows”.

    There have been a lot of efforts to try to protect the lions, but it's a crisis and everyone is looking for a solution. One idea was land leases(租用), another was lion-proof fences. However, no one even knew that Richard Turere, a 13-year-old Maasai from Kenya, had already come up with something that worked.

    One night Richard was walking around with a flashlight and discovered the lions were scared of a moving light. An idea was born. Three weeks and much repairing later, Richard invented a system of lights that flash around the cow shelter, mimicking a human walking around with a flashlight. His system is made from broken flashlight parts and an indicator box from a motorcycle. “The only thing I bought was a solar panel（电池板）, which charges a battery that supplies power to the lights at night.” Richard says. He calls the system Lion Lights.

    His simple solution was so successful: his neighbors heard about it and wanted Lion Lights, too. He put in the lights for them. From there, the lights spread and are now being used all around Kenya. Someone in India is trying them out for tigers. In Zambia and Tanzania they're being used as well.

    Patients with light or moderate depression can be successfully treated by swimming with dolphins, researchers said on Saturday.

    The study was carried out in Honduras, including patients who were thought by the doctors with light of moderate depression coming from the United States and Honduras.

    For two weeks, half of the group swam and snorkeled (潜泳) with dolphins for an hour a day. At the same time the other half group carried out the same type of water activities, but with the absence of dolphins. Researchers want to find out the influence of water and the natural setting.

    All the study volunteers didn't continue to take any drugs or psychotherapy ( 心理治疗) at least for weeks before the start of the study and did not take any drugs during the study, said the researchers from the division of clinical Psychiatry at t e the University of Leicester Medical School.

    By the end of the study, those people who swam with the dolphins had a greater average reduction in their depressive symptoms than those who did not.

    The researchers noted that the study supports the theory of biophilia, which thinks that human health and well-being depends partly on the human connection with the natural world. The findings appeared in the issue of the British Medical Journal.

    Coming from the Greek, biophilia means “love of life”, and it has been developed by biologists to reflect the humans' natural tendency to connect with nature and animals, leading to interactions and positive emotions that result in psychological treatment.

    It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night together. Just as you start to get ready, your dad reminds you it is your aunt's birthday and the whole family is going out to dinner to celebrate. How can this possibly end without a huge argument?

    One of the greatest sources of tension (紧张) between teenagers and their families is the struggle to balance personal desires with family expectations. As you are getting older, you are becoming more independent and more interested in being with your friends. However, at the same time, your family is trying to figure out(弄清楚) how to deal with these changes. While you once spent most of your free time with your family, you are now often absent from home. Parents may get their feelings hurt. Or they might feel that they are losing control of their family during this period. You might feel angry that so many family demands are placed on you.

    There are a few things you can try to make it a little easier to ease the tension.

    Make your plans ahead of time. Ask your parents if there is anything else planned at that time.

    When something with your friends interferes (冲突) with a family event, try to figure out if there is any way you can do both.

    Suggest something you would really like to do with your family. Sometimes parents feel better just knowing their teenager wants to spend time with them.

    Some of the time you won't be happy with the outcome. You might either have to disappoint your parents or have to miss out being with your friends. However, if you show consideration for the feelings of both your family and your friends, you can solve the problem in a tender（和善的）way.

    It's school time again! You're probably feeling excited and maybe a little sad that summer is over. Some kids feel nervous or a little scared (害怕的) on the first day of school because of all the new things: new teachers, new friends, and even a new school. Luckily, these "new" worries only stick around for a little while. Let's find out more about going to a new school.

    Most teachers kick off the new school year by introducing themselves and talking about all the stuff you'll be doing that year. Some teachers give students a chance to tell something about themselves to the rest of the class, too. When teachers do the talking on the first day, they often go over classroom rules and school rules so you'll know what's allowed and what's not. Please pay close attention.

    You might already know a lot of people in your classes on the first day, but it's a great day to make new friends, so try to say hello to kids you know and new ones that you don't. Make the first move and you'll be glad, and so will your new friends!

    Seeing friends you haven't seen in a while can make the first day a good one. You can make the day feel special by wearing clothes that you really like. Maybe you got a great T-shirt on one of your vacations, or a pair of sneakers (运动鞋). It also can make you feel good to be prepared and have all the things you need, such as pencils, folders, and whatever else you'll be needing. But make sure that you pack them the night before in case you don't have time in the morning.

    Scientists have been studying how people use money for long. Now they're finding some theories may apply to one group of monkeys.

    Researchers recently taught six monkeys hos to use money. They gave the monkeys small metal disks (圆片) that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if they gave one of the disks to a scientist, they'd receive a piece of apple in return.

    If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys on apple piece, while Allison always showed two pieces. But that's not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random.

    Experiment One: Allison showed two pieces of apples but gave both piece only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison.

    Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake.

    In the first experiment, the monkeys correctly figured out that if they traded with Allison, they'd end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like a gain. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they'd rather take a chance of seeming to win than seeming to lose.

    We also sometimes make silly business decisions just to avoid the feeling that we're getting less, even when we're not. Would you have made the same choices?

Graduating is indeed a momentous occasion that calls for a memorable celebration. Here are some destinations that could make your post-graduation vacation truly special:
