单选题Don Bruns of Lima, Ohio, and his 11- year-old son, Aaron, love baseball, and the Cincinnati Reds in particular. For, Aaron's birthday last October, his dad decided to drive him to Cincinnati more than two hours away, for the first game of the World Series. They had no tickets but hoped to buy a pair from scalpers. After arriving at Riverfront Stadium, the Brunses walked the streets for two hours. Aaron wearing a Reds cap, his father carrying a sign that said "We Need 2 Tickets." "There were a lot of scalpers," the father said." But the cheapest ticket was $1075 a piece. I couldn't afford that." And Aaron understood. Then the boy and his father were approached by Michael Teicher, who worked for a company that produces baseball highlight show for TV. Teicher pulled out a pair of tickets and handed them to Bruns. "How much do you want?" Bruns asked. "No charge," said Teicher, "Enjoy the game." When asked later, Teicher explained: "I was working for a man named Joe Podesta who hadn't missed a World Series in 16 years. (78)But he'd had a mild heart attack in September and couldn't make it this time. So he told me to give the two tickets away. The only ground rule he set was to give the tickets to people I thought would be thrilled." Teieher walked around town for some time before seeing Don and Aaron Bruns. "A lot of people looked like they might just take the tickets and sell them," Teicher said, "Then I saw this guy and his son, a nice - looking skinny kid with glasses, and he seemed very disappointed. (79) They reminded me of my dad and me when I was a kid. I would have died to go to a World Series game with my father. But I never did." How important was it to Don Bruns and his son? Here is what Bruns said: "It's the most memorable thing that ever happened to us. My boy and I must have turned to each other 30 times during the game and said 'I can't believe this.’ We'll never forget that night./

单选题Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and hear the politicians before an election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are less patient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen.

单选题Questions 1 to 5 are based on the following passage: When we talk about intelligence, we do not mean the ability to get good scores on certain kinds of tests or even the ability to do well in school. By intelligence we mean a way of living and behaving, especially in a new or upsetting situation. If we want to test intelligence, we need to find out how a person acts instead of how much he knows what to do. (76) For instance, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him. He tries to find out all he can, and then he acts immediately and tries to do something about it. He probably isn't sure how it will all work out, but at least he tries. And, if he can't make things work out right, he doesn't feel ashamed that he failed; he just tries to learn from his mistakes. An intelligent person, even if he is very young, has a special outlook on life, a special feeling about life, and knows how he fits into it. If you look at children, you'll see great difference between what we call "bright" children and "notbright" children. They are actually two different kinds of people, not just the same kind with different amount of intelligence. For example, the bright child really wants to find out about life: he tries to get in touch with everything around him. (77) But, the unintelligent child keeps more to himself and his own dream world; there seems to be a wall between him and life in general.

单选题I'm (old enough) (not) to let my troubles (to interfere) (with) my work.

单选题By adopting a few simple techniques, parents who read to their children can greatly increase their children"s language development. It is surprising but true. How parents talk to their children makes a big difference in-the children"s language development. If a parent encourages the child to actively respond to what the parent is reading, the child"s language skills increase. A study was done with 30 three-year-old children and their parents. Half of the children participated in the experimental study; the other half acted as the control group. In the experimental group, the parents were given a two-hour training session in which they were taught to ask open-ended questions rather than yes-or-no questions. For example, the parent should ask, "What is the doggie doing?" rather than "Is the doggie running away?" The parents in the experimental group were also instructed in how to help children find answers, how to suggest alternative possibilities and how to praise correct answers. At the beginning of the study, the children did not differ in measures of language development, but at the end of one month, the children in the experimental group showed 5.5 months ahead of the control group on a test of verbal expression and vocabulary. Nine months later, the children in the experimental group still showed an advance of 6 months over the children in the control group.
