Television, which made its first serious appearance in 1939, did not become common until the early 1950s. Since then. millions of children have grown up in front of the set, and many people now worry about the effect that TV has on the young, and on society in general. Many ordinary parents wish it had never been invented.
Like almost anything else, television has its good and its bad sides. One should surely thank its inventors for the joy and the interest that they have brought into the lives of the old, the sick. and the lonely --all those who, without it, would have no pleasure and no window in the world.

[简答题] That experiences influence subsequent behaviour is evidence of an obvious but nevertheless remarkable activity called remembering. Learning could not occur without the function popularly named memory. Constant practice has such effect on memory as to lead to skillful performance on the piano, to recitation of a poem, and even to reading and understanding these words. So-called intelligent behaviour demands memory, remembering being a primary requirement for reasoning. The ability to solve any problem or even to recognize that a problem exists depends on memory. Typically, the decision to cross a street is based on remembering many earlier experiences. Practice (or review) tends to build and maintain memory for a task or for any learned material. Over a period of no practice what has been learned tends to be forgotten; and the adaptive consequences may not seem obvious. Yet, dramatic instances of sudden forgetting can seem to be adaptive.
