American children arent the only couch potatoes with nearly one third of children globally spending three hours a day or more watching TV or on computers， according to a study of over 70，000 teens in 34 nations.

From Argentina to Zambia， Regina Guthold of the World Health Organization in Geneva and her colleagues found most children arent getting enough exercise and it made no difference whether they lived in a rich or a poor country. “With regard to physical activity levels， we did not find much difference between poor and rich countries，” Guthold said. The study looked at 72，845 schoolchildren aged 13 to 15 from North and South America， Asia， Europe， Africa and the Middle East.

The researchers explained that plenty of physical activity means at least an hour of exercise outside of gym class at least five days a week. Children who spent three or more hours a day watching TV， playing computer games， or chatting with friends online—except for time in school or time spent doing homework—were classified （归类） as sedentary.

The researchers found only one quarter of the boys and 15 percent of the girls were getting enough exercise by these explanations. A quarter of boys and nearly 30 percent of girls were sedentary and didnt get enough exercise with girls less active than boys in every country except for Zambia.

Uruguay had the highest percentage of active boys， at 42 percent， while Zambia had the lowest， at 8 percent. Girls from India were the most active， with 37 percent getting enough exercise， while girls from Egypt were the least active， with just 4 percent getting plenty of exercise. Children in Myanmar were the least sedentary， with 13 percent of boys and 8 percent of girls classified as sedentary. The most sedentary nations were St. Lucia and the Cayman Islands， with 58 percent of boys and 64 percent of girls spending at least three hours a day in sedentary activity.

People showed a deep concern for kids lack of physical activity in various nations. Why do they have a low level of physical activity？ Guthold thought that urbanization （都市化） could be a factor as well as access to cars and TVs.

With S. E. Hintons The Outsiders coming out in 1967， a new kind of literature， young adult literature， appeared. Previous to this time， society generally recognized two age groups， school-age children and adults， and books and magazines were for the needs and interests of each. However， after the Second World War， a newly recognized life stage called adolescence came into being， consisting of high school and college students who had outgrown （因长大而放弃） the books of children， but were not quite ready for the more lengthy and complex books of their parents and teachers.

The new young adult literature is written especially for them. Authors write works on a reading level and a maturity level suitable for young adult readers. Readers enjoy characters that are just like them. The American Library Association recognizes the value of these well-written works in encouraging students to read， and increasing their understanding and critical thinking skills along with a love of literature.

Teen Reads is designed to meet the needs of students who meet young adult literature for perhaps the first time， whether it is for a school assignment （作业） or just for more information about a favorite book and its author.

After an introductory chapter providing an overview of the author and his or her approach to writing， a biography chapter will detail （详述） the history of the authors life and the experiences that had an effect on his or her works， and the authors writing process and future goals. The chapters that follow will concentrate on one novel or short story collection each. They will talk about the plot， main characters， settings， and themes of the story. At the end of each chapter will be web resources for additional reading. Teen Reads， written in a friendly style， will help students achieve a greater understanding and appreciation of the young adult novels they read.

Street art， a very popular form of art spreads quickly all over the world. You can find it on buildings， sidewalks， street signs and trash cans from Tokyo to Paris， from Moscow to Cape Town. 1 Even art museums and galleries are collecting the works of street artists.

Street art started very secretly because it was illegal to paint on public and private property without permission.

2 Some think it is a crime and others think it is a very beautiful new form of culture. Art experts say that the street art movement began in New York in the 1960s. Young adults painted words and other images on the walls and trains. This colourful style of writing became known as graffiti （涂鸦）， whose art showed that young people wanted to rebel against society.

Street artists do their work for different reasons. Some of them do not like artists who make so much money in galleries and museums. 3 Some artists try to express their political opinion in their works. Others like to do things that are not allowed and hope they cant be caught. Advertising companies also use street art in their ads because it gives people the impressions of youth and energy.

4 Artists can show their pictures to people all over the world. Many people， however， say that seeing a picture on the Internet is never as good as seeing it alive.

5 There， it will continue to change and grow.

A. Street art has become a global culture.
