Justin Bieber is only fifteen years old and has become very popular already. He was raised (抚养) by his mother in Stratford, Ontario, Canada. When he was twelve he won second place in a local singing contest. He started posting (贴) videos of his contest performances on the Internet for his friends and family. Soon these videos had been seen more than ten million times.

    A music manager saw those videos and asked Justin to fly to Atlanta, Georgia, to meet the singer and songwriter Usher. A year later Justin released (发行) his first albumMy World. It sold over a million copies in the first two months. Four singles were released before the album. All became popular. This made Justin Bieber the only singer in the history of the Billboard magazine to have four singles from his first album among the most popular songs before the album's release.

    Justin Bieber performed for President Obama at the White House last December. He was part of a musical show that raised money for the National Children's Medical Center. He was also among the many singers who recorded the song We Are the World. The song was produced to raise money for Haiti. The video has been seen more than seven million times on the Internet. And it was shown during the opening ceremony of the 2010 Winter Olympics in Vancouver.

    Justin Bieber's family did not have much money when he was young. He did not have as much so other children did. Justin says he wants to influence young people in a good way. He believes that you can do anything if you put your mind to it.

    Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant still faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation—land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local famers to improve their life in order to encourage them to protect rather than destroy elephants.

    It is important to know another language and how to communicate without words when you are in another country. Before saying anything, people communicate with each other by using gestures(手势). However, many gestures have different meanings, or no meaning at all, in different parts of the world.

    In the United States, nodding your head up and down means "yes", while in some parts of Greece and Turkey, it means "no". In the southeast of Asia, it is a polite way of saying "I heard you".

    Today in the USA, when someone puts his thumb up, it means "Everything is all right." However, in Greece it is bad. Also putting your clasped(紧握的)hands up above your head means "I am the winner." It is the sign which players often make. In Russia it is the sign of friendship.

    In the USA, holding your hand up with the thumb and index finger(食指), and the other three straight means "Everything is OK." In France, it means "You are worth nothing."

    It is also important to make eye communication. If you look down when talking to an American, he or she may feel that you are shy, or you are trying to hide something.

Besides these, you should also know there are some topics that cannot be talked about, such as age, weight and marriage. You can talk about the weather, work, sports, food, where one lives and news of the day.

    At least 12 other murders since 1997 have been linked to an addiction to violent video games. This year, the parents of a 14-year-old murder victim in the UK blamed the killer's addiction to the game Manhunt, causing a government review of legislation (立法) to protect children.

    But is there any scientific evidence that mere games can make children and young adults more aggressive, or possibly have the desire to murder? There is no doubt children are being exposed to more games violence than ever: around a quarter of all games released in the US contain some violence. And the violence is becoming more obvious as increases in computing power make the games look ever more realistic.

    Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to use weapons as second nature. Secondly, violent games provide repetitive aggressive experiences that are rewarded by more killing.

    Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, Craig Anderson of Iowa State University in Ames and his colleague Karen Dill found that people who played violent games were more likely to admit to aggressive behaviour, including attacks or robberies.

    Earlier this year, Krahe and her colleague Ingrid Miller reported a study of 13 to 14-year-old children. More than half had played games recommended only for over-18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Other authors in the same edition report that children who play violent games more likely to argue with teachers and fight with others.

    Experimental studies have also pointed out a possible link. In one, Anderson and Dill asked a group of students to play a violent game, Wolfenstein 3D, while another group played the non-violent Myst. Those who played the violent game were faster to react to aggressive words flashed on screen and appeared more aggressive.

    The issue is controversial, however. Jeffrey Goldstein, a psychologist at the University of Utrecht in the Netherlands and a consultant to some video games publishers, agrees that there is good evidence that children, who are exposed to violent media, including video games, are more aggressive. But he warns it might not be a simple case of cause and effect: aggressive kids might be most attracted to violent games.

    On Sunday, November 3, 2019, most North Americans will mark the end of Daylight Saving Time (DST) by moving their clocks back an hour. This simple action will not only add an extra 60 minutes to their weekend, but also shift (变换，变动) daylight back into the morning hours, making it a little less painful to wake up for school and work during the shorter winter days.

    Operating the clocks was first suggested by Benjamin Franklin in 1784. He mentioned the idea in a letter to the editor of the Journal of Paris and advised it should be a way to save candles, but it was not taken seriously. George Hudson from New Zealand also recommended moving the clocks back two hours in 1895 to get extra daylight time to study insects. Unfortunately, neither he nor British people William Willett, who suggested it in 1907 as a way to save electricity costs, got their wish.

    It was the German Empire that began the clock shifting tradition on April 30, 1916, to save fuel needed to produce weapons and bombs for World War I. Though a few others, including the US and Britain, adopted the tradition shortly after, all the countries returned to Standard Time once the war ended, only to start DST again during World War II. Once the battle ended in 1945, the US government ended DST nationally but allowed states and districts to continue the tradition and even allowed them to establish their own start and stop dates.

    However, though there have been many attempts to persuade lawmakers to end DST, both in the US and Europe, they have not been successful. Therefore, unless you live in places like Hawaii and Arizona, you have little choice but to "Fall Back" and enjoy the extra hour this weekend! Health experts suggest the best way to adjust is going to bed at your regular time, even if the day is an hour longer.
