Directions: Read the passage carefully and answer the questions or complete the statements in the fewest possible words.

　　Many parents who welcome the idea of turning off the TV and spending more time with the family are still worried that without TV they would constantly be on call as entertainers for their children. They remember thinking up all sorts of things to do when they were kids. But their own kids seem different, less creative, somehow. When there’s nothing to do, these parents observe regretfully, their kids seem unable to come up with anything to do besides turning on the TV.

　　One father, for example, says, “When I was a kid, we were always thinking up things to do, projects and games. We certainly never complained in an annoying way to our parents, ‘I have nothing to do!’” He compares this with his own children today: “They’re simply lazy. If someone doesn’t entertain them, they’ll happily sit there watching TV all day.”

　　There is one word for this father’s disappointment: unfair. It is as if he were disappointed in them for not reading Greek though they have never studied the language. He deplores(哀叹) his children’s lack of inventiveness, as if the ability to play were something innate(天生的) that his children are missing. In fact, while the tendency to play is built into the human species, the actual ability to play — to imagine, to invent, to elaborate (描述) on reality in a playful way — and the ability to gain fulfillment from it, these are skills that have to be learned and developed.

　　Such disappointment, however, is not only unjust, it is also destructive. Sensing their parents’ disappointment, children come to believe that they are, indeed, lacking something, and that this makes them less worthy of admiration and respect. Giving children the opportunity to develop new resources, to enlarge their horizons and discover the pleasures of doing things on their own is, on the other hand, a way to help children develop a confident feeling about themselves as capable and interesting people.
