What hasn't changed is the way Britannica creates its material. The company has thousands of expert writers and more than 100 editors. Contributors include many scholars, Nobel _ and world leaders, such as Bill Clinton and Desmond Tutu. Britannica's website also provides educational tools. At Britannica Online School Edition, teachers share lesson plans. Online versions of the encyclopedia serve more than 100 million people around the world. The company plans to mark the end of print edition by making the contents of its website free for one week.

Read the following article and select the best answer. Article: Blogging may have psychological benefits for teens suffering from social anxiety, improving their self-esteem and helping them relate better to their friends, according to new research published by the American Psychological Association. "Research has shown that writing a personal diary and other forms of expressive writing are a great way to release emotional distress and just feel better," said the study's lead author, Meyran Boniel-Nissim, PhD, of the University of Haifa, Israel. "Teens are online anyway, so blogging enables free expression and easy communication with others." Blogging has a stronger positive effect on troubled students' well-being than merely expressing their social anxieties and concerns in a private diary, according to the article published online in the APA journal Psychological Services(r). Opening the blog up to comments from the online community intensified those effects. The researchers randomly surveyed high school students in Israel, who had agreed to fill out a questionnaire about their feelings on the quality of their social relationships. A total of 161 students -- 124 girls and 37 boys, with an average age of 15 -- were selected because their scores on the survey showed they all had some level of social anxiety or distress. All the teens reported difficulty making friends or relating to the friends they had. The researchers assessed the teens' self-esteem, everyday social activities and behaviors before, immediately after two months and after the 10-week experiment. Four groups of students were assigned to blog. Two of those groups were told to focus their posts on their social problems, with one group opening the posts to comments; the other two groups could write about whatever they wanted and, again, one group opened the blog up to comments. The number and content of comments were not evaluated for this experiment. The students could respond to comments but that was not required. Two more groups acted as _ -- either writing a private diary about their social problems... Question: From the experiment we can know that _ . - writing private diaries makes no difference to the relief of one's emotional stress - teenagers opening their blogs up to comments have more psychological benefits - the positive effects of expressing one's emotions by blogging don't last very long - those describing bad relationships on blogs tend to develop more mental problems
teenagers opening their blogs up to comments have more psychological benefits

Anti-smoking activists at the second "Tobacco or Health" conference in the Canary Islands pointed out that while grown-ups were giving up smoking in ever-growing numbers, more and more young people were taking up the habit, particularly girls. One 15--year--old in four is a regular smoker, according to a study made in 27 countries in Europe and the United States, Canada and Israel----Edinburgh University together with the World Health Organization. In Western Europe, girls were more likely than boys to smoke. In prefix = st1 /Germanyor In England, one third of the girls were smokers compared to one in four boys.

Read the following article and select the best answer. Article: Fortunately for early humans,the huge primate's diet consisted mainly of bamboo. Scientists have known about Gigantopithecus since some of its teeth were discovered on sale in a Hong Kong pharmacy about 80 years ago.The idea of a giant ape aroused the interest of scientists around the world,but It remained unclear when this beast became extinct. Now Jack Rink,a geochronologist at McMaster University in Canada,has used a high-precision -dating method to determine that this ape-the largest primate ever--roamed Southeast Asia for nearly a million years before the species died out 100,000 years ago.By this time,humans had existed for a million years. "Gigantopithecus is a primate that co-existed with humans at a time when humans were undergoing a major evolutionary change,"said Rink. Some of Gigantopithecus fossils were found in Guangxi.It is the region where some believe the modem human race originated.according to Rink.Scientists have been able to piece together a description of Gigantopithecus using just a handful of teeth and a set of jawbones. "The size of these specimens--the crown of the molar,for instance,measures about an inch (2.54 cm)across--helped us understand the extraordinary size of the primate,"Rink said. Scientists can only guess at what killed off a beast this size.Some scientists believe that a diet of bamboo combined with increasing competition from more nimble humans eventually led to its extinction. While most scientists agree that Gigantopithecus died out long ago,some people--Big-foot and Yeti enthusiasts in particular-believe that this ape is the source of tales of giant,hairy beasts living in the woods. Even though mainstream scientists dismiss these claims,it isn't impossible.The coelacanth a type of fish thought to have died out millions of years ago-was discovered swimming off the coast of Africa in 193& Question: Which of the following description about the huge apes is right? - They died from the bad habitats. - They died out long time ago. - They died of hunger. - These giant hairy beasts,living in the frost,are legends.
