问题 单项选择题

若把操作系统看做计算机系统资源的管理者, (6) 不属于操作系统所管理的资源。

A.内存

B.中断

C.CPU

D.程序

答案

参考答案:B

解析: 操作系统可以管理系统的各种资源,包括所有硬件资源,如CPU、存储器、输入输出设备等和软件资源,如程序和数据等。中断是指CPU对系统发生的某个事件作出的一种反应,即CPU暂停正在执行的程序,保留现场后自动转去执行相应的处理程序,处理完该事件后再返回断点继续执行被“打断”的程序。所以说,中断不属于操作系统所管理的资源。

More than ever, kids today have given up reading for activities like watching TV, playing video games and surfing the Internet, but recently a new trend (趋势) has been catching on that will hopefully change that.

In fact, book clubs are becoming more popular among American kids. 11-year-old Kenya Debarros read about singer Lena Horne. “It was just amazing to see a black woman as the star and not just a mammy or a maid,” she says. But did all these kids come enthusiastically (热情地)? No, not exactly.

“I like book club, uh, I don’t know, but I am just trying it out. My mom didn’t make me, but I just tried it out,” says 16-year-old Antonio Nash.

And if they’ll try it, the experts say, there are ways to get them to come back. Make it fun, serve pizza, serve chocolate cakes and have door prizes (门票对号奖). It also helps to connect books to the real world. They talk about things that are happening in the community, so they can relate whatever they’ve read in the book to what’s happening now.

Here they have long talks about the books they have selected, which most kids don’t get to do when they’re in school, and these kids say, in book clubs they’re learning to love books and love reading.

“I feel like I’m actually in the book and doing what the actual main character is doing,” says 13-year-

-old Justin Woodard.

16-year-old Antonia McManus says reading gives her a nice break from the day, “Sitting down and reading a book gives me some time to get away from the world, and get my mind straight.”
