Article: Last year, over 206,000 students from the United States studied abroad. Does that number surprise you? These students already know the benefits of studying abroad. You may be wondering why you should study abroad. Here are some answers for you. * Timing The absolutely best time in your life to study abroad is when you are in college. If you miss this opportunity, it's almost impossible for you to do it later in life. * To gain cross-cultural experience Life overseas makes you see your everyday world in a whole new light. You don't even realize it, but our culture shapes the way we view the world and affects us every minute of the day. Differences in culture are more than just differences in language, food, clothing and art. * To improve your communication skills and your self-confidence People who study abroad tend to be willing to take risks, willing to put themselves in unusual situations, and able to solve problems. * To become more fluent in a language or to learn a new language The world market is becoming smaller, and many companies require a second language. Foreign languages are not only valuable in the job market but also valuable in the real world. * For the adventure Travel to other cities within your host country and around neighboring countries. As you get to know your new classmates, roommates, and host family, you will gain a unique view on the host culture. Discover the differences and, more importantly, the many similarities between your worlds. The friendships you make will last long after the program. * To learn more about yourself Find out who you really are. What are your limits? How do you overcome the difficulties you've never _ before? How independent are you? These questions are hard to answer until you are removed from your usual surroundings. After solving difficult problems on your own overseas, you'll find that almost nothing will confuse you at home. Students who study abroad commonly report that their study abroad experience actually changed their lives.

Article: Elephants and people are in competition for space. In much of Africa, elephants are now put in national parks. Elephants suffered a serious and steady decrease in numbers in the 1970s. This was the same time when scientists were beginning to learn a great deal about elephants and their behavior. Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of communication. In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 to 25,000. The sharp drop in numbers was the result of poachers illegally killing elephants for their ivory. The price of ivory went from $3 a pound to $50 to $100 a pound. Africa became very attractive to poachers. Bull elephants carried the largest tusks , so they were more often killed. With males gone and older females killed by poachers as well, there were many young elephants unable to benefit from the wisdom of the older females and matriarchs, who lead the herds. Kenya took a stand, international trade in ivory was officially forbidden, and $3,000,000 worth of confiscated ivory was burned in Kenya. The following year, only 50 elephants were lost to poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world. People throughout Africa won't tolerate elephants eating their crops and destroying their livelihoods. In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there were some attempts at birth control to keep the elephant population at manageable numbers to reduce conflicts with people. Faced with a growing human population, elephants are losing the battle for space. It's unlikely, though, that they will become extinct. They will live in natural parks that bring tourists to Africa as well as India and other parts of Asia. The money from tourism will help elephants to survive.
Question: Bull elephants were at higher risk of being killed because _ .
Options: (A) they were the leaders of the herds (B) they possessed bigger ivory (C) they were of smaller size (D) they ran slowly

Article: Friendlies abandoned as name for mascots The name "Friendlies" has been abandoned as the organization committee for the 2008 Beijing Olympics silently changed the English name of the Games' five mascot dolls last week. The organization committee decided to adopt the name "Fuwa", which is a pinyin translation of its Chinese name and is more frequently used in prefix = st1 /China. However, the organization committee replaced all Friendlies to Fuwa on its official site, but without giving a formal announcement to inform the public of the change. It is said that they received an inside notice about the change last week but don't want to emphasize it for fear of affecting the sales of Olympic goods. Li Yanjun, a Legal Affairs Department official, said the decision was made considering a variety of reasons but did not want to comment on them. "You may know about the background and many unfavorable comments concerning the mascots' former name across the web, but I won't comment on them," Li said. "I'm not in the position to make it clear if the change was caused by this." A report published last week on China Radio International (CRI)made the name change known and listed the reasons why the Friendlies name should be changed. "Firstly, Friendly is somewhat an unclear name, which could refer both to friendly people and friendly matches,"a Dr. Li from LanzhouUniversitywas quoted as saying on the site. "Secondly, the term Friendlies has a similar pronunciation to 'friendless' and thirdly, the spelling of Friendlies could be split as 'friend lies'." Laura Fitch, a Canadian who works in Chinaas news editor, welcomed the change, saying the name Friendlies sounds a "a little bit childish" and "doesn't really have a meaning."
Question: why did the organization committee change the name "Friendlies" into "Fuwa" without giving a formal announcement?
Options: (A) Because it is not important to make it known. (B) Because everybody will know it by surfing the internet. (C) Because it will perhaps affect the sales of Olympic products. (D) Because all the people will criticize them for changing its name.
