Working parents and teachers see after-school programs no longer as optional, but as an essential support for children as they grow and develop, according to a new national study of after-school programs, released by Reader’s Digest Funds. Nearly 80 percent of parents surveyed in the study said that after-school programs helped their children cope with behavioral problems and helped them obtain new skills to meet increased demands in school.
At a time when states and the federal government are pressing harder than ever for improved academic achievement by all children, a three-year study shows that after-school programs, particularly in low-income communities, are an effective and affordable way not only to keep children safe and out of trouble, but also to keep them engaged in school. The report concludes that children in school-based after-school programs benefit both academically and socially in programs that offer a diverse set of activities. The report findings
A. improving children's academics performance.
B. helping parents get better jobs.
C. making children be more obedient.
D. making children be more independent.
| Astronaut Jim Voss has enjoyed many
memorable moments in his career, including three space flights and one space
walk. But he recalls with special fondness a decidedly earthbound (为地球引力所束缚的)
experience in the summer of 1980, when he participated in the NASA-ASEE Summer
Faculty Fellowship Program. Voss, then a science teacher at West Point, was
assigned to the Marshall Space Flight Center’s propulsion (推进) lab in Alabama to
analyze why a hydraulic fuel pump seal on the space shuttle was working so well
when previous seals had failed. It was a seemingly tiny problem among the vast
complexities of running the space program. Yet it was important to NASA because
any crack in the seal could have led to destructive results for the astronauts
who relied on them. "I worked a bit with NASA engineers," says Voss, "but I did it mostly by analysis". I used a handheld A. Ⅰonly B. Ⅱonly C. Ⅰ,Ⅱand m all included D. ⅠandⅡonly [单选题]向日葵是（ ）的国花。
