题型:单项选择题

Ayesha and Latisha Jones need to take a break in their own homework to help their dad, because at the age of 52, John Jones is just now learning to read.

“I was so uncomfortable and so ashamed,” he said. For many years, unable to read a menu or a bus schedule, Jones was just one of the estimated 65,000 adults in Buffalo, New York who cannot read above a 5th-grade level.

And a new study shows the problem is getting worse in many states. California, New York and Florida have all shown surprising increases in illiteracy(文盲)rates. The situation has improved in a few states, like Mississippi, Rhode Island and Kentucky. But worldwide, the United States doesn’t perform well.

Fourteen countries rank higher in reading ability than the United States, including Finland, Canada, New Zealand, Australia, Ireland, South Korea, UK, Japan, Sweden, Iceland, Belgium, Austria, France and Norway.

Back in Buffalo, a program called Read to Succeed targets the problem early, teaching preschoolers shapes, colors and letters.

“We have a lot of poverty and that means a lot of children don’t have the skills, but they have the potential(潜质),” said Helene Kramer of Read to Succeed. The theory is : you’re never too young or too old to learn.

Working with Buffalo’s literacy volunteers has given Jones a fresh start. “They gave me a chance to open a door that I could never open before,” he said. “I could never open it before, because I couldn’t read.” It’s not easy, but Jones says seeing his daughters read inspires him to try.
