Ⅲ.阅读理解

At the East Los Angeles Library, even the youngest readers have to pay their fines (罚款) － but not the way you think. Card holders 21 and under can read away their late fees (费用) at a rate of $5 per hour, according to CBS (Columbia Broadcasting System) reporter Jamie Yuccas. It's a new period of time for Los Angeles County, a program called “The Great Read Away.”
“We're not really focusing (集中) on what they're reading so long as they're reading here，” LA County Library Director Skye Patrick said. He said the idea came about after the library noticed a disconcerting fact: Many kids who had debts on overdue (逾期的) books or movies would stop coming to the library altogether.
“Ten dollars, for some people is a huge amount，” Patrick said.
“And those are the kids that you want in the library？” Yuccas asked.
“That's exactly right, so the purpose of this program is really to invite them back into the library, to make libraries open to them and their families，” Patrick said.
In a reading room, Yuccas found 8­year­old Jaylene Robles working off her late fee while also catching up on the popular “Judy Moody” series.
“When you didn't have to pay money for your fines, and you could read away your fines, what did you think？” he asked her.
“I was surprised... I thought everyone in the library or someone that has a fine, would have to pay，” Robles said.
Children's librarian Xuemin Zhong said she sees kids reading away fees daily.
“I've seen as low as a couple of cents to as high as a couple hundred dollars，” Zhong said. “And I've seen kids read that away because they have a duty to do so.”
Since the program started last year, LA County said its more than 80 libraries have recorded more than 50,000 reading periods and opened more than 13,000 blocked accounts (被封账号)．
【语篇解读】　本文是议论文。美国洛杉矶县图书馆允许21岁及以下读者通过在图书馆阅读的方式支付逾期罚款。

2．What does the underlined word “disconcerting” in Paragraph 2 probably mean?
