Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said. The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age. “The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement. The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls. The findings were published in the journal Developmental Science. 24. In which aspect do children benefit from puzzle play? A. Building confidence. B. Developing spatial skills. C. Learning self-control. D. Gaining high-tech knowledge. 25. What did Levine take into consideration when designing her experiment? A. Parents’ age. B. Children’s imagination. C. Parents’ education. D.

But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠). Unusual fashion shows in New Orleans and Brooklyn have(showcased)nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur. Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month. Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field. The fur trade kept nutria check for decades,but when the market for nutria collapsed in the late 1980s,the cat-sized animals multiplied like crazy. Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur. Then there’s Righteous Fur and its unusual fashion. Morgan says,”To give people a guilt-free option that they can wear without someone throwing paint on them-1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly. 28. What is the purpose of the fashion shows in New Orleans and Brooklyn? A. To promote guilt-free fur. B. To expand the fashion market. C. To introduce a new brand. D. To celebrate a winter holiday. 29. Why are scientists concerned about nutria?A. Nutria damage the ecosystem seriously. B. Nutria are an endangered species. C. Nutria hurt local cat-sized animals. D. Nutria are illegally hunted. 30. What does the underlined word “collapsed” in paragraph 5 probably mean? A. Boomed. B. Became mature. C. Remained stable. D. Crashed. 31. What can we infer abouf wearing fur in New York according to Morgan? A. It’s formal. B. It’s risky. C. It’s harmful. D. It’s traditional. 【答案】28. A 29. A 30. D 31. B 【词汇】 1. enthusiast 2. wetland 3. concern 4. collapse 5. multiply 6. convince 7. promote 8. righteous 9. option 10. massive 11. admit 12. morally 13. expand 14. brand 15. ecosystem 16. damage 17. endangered 18. illegally 19. stable 20. mature 21. boom 22. risky 1. enthusiast n. 热心人;热衷者 2.
