　　Some television programs are educational， informative and inspiring， and are often more effective than books in bringing children a wide scope of knowledge. Common questions， such as how a tree grows， why it snows in the winter and what the Great Wall is， can be answered in television shows. What children learn from television can be a vital complement to their school learning. When children who frequently watch educational programs on television take elementary school classes， they are more likely to receive higher grades and value their studies more than their fellow students. Also， according to a latest study conducted by a group of scientists from the University of Siena in Italy， television programs， particularly cartoons and comedies， are effective sources of relief to children who are under intense pressure or in severe pain.
