[填空题]One theory about the universe says that it has no boundary, no edge. This theory was proposed by Stephen Hawking and Jim Hartle. It says (81) that the universe has a finite area, but no one travelling through the universe would ever come to a point that the universe stops. This (82) would be similar to journey over the surface of Earth. We can travel (83) around the world without reaching boundaries nor edges, yet the area of (84) the planet is finite. This no boundary theory predicts what the universe (85) does have a beginning and an end, but it differs off the traditional (86) Big Bang theory in some ways. The traditional Big Bang theory assuming that the beginning of the universe was a singularity, a point (87) of infinite density and infinitesimal volume to where space and time (88) became distorted. Instead, Hawking and Hatle predict that the beginning of the univ

Many people are worried about what television has done to the generation of American children who have grown up watching it. For one thing, recent studies show that TV weakens the ability to imagine. Some teachers feel that television has taken away the child’s ability to form mental picture in his own mind, resulting in children who cannot understand a simple story without pictures.
Secondly, too much TV too early usually causes children to be removed from real-life experiences. Thus, they grow up to be passive(被动的) watchers who can only respond to action, but not start doing something actively.
The third area for such a worrying situation is the serious dissatisfaction frequently expressed by school teachers that children show a low patience for the pains in learning.

C. what bad effects TV program have on children
