The storage of classified (分类的) research at all 24 labs run by the US Department of Energy was shut down this week after officials decided that the security (安全) problems recently found at the Los Alamos National Laboratory in New Mexico might also exist elsewhere.
Several computer disks went missing at Los Alamos earlier this month, forcing Energy Secretary Spencer Abraham to stop all work at the lab until the problems are found out. As of 26 July, two missing disks had still not been found, and 15 employees had been suspended in connection with the disappearance.
Now all energy labs will stop doing classified research that involves(需要) removable storage devices --- such as computer disks --- until all the devices are given explanation for and new procedures are in place for monitoring their handling by laboratory employees.
"While we have no evidence that the problems being investigated are present elsewhere, we have a responsibility to take all necessary action to prevent such problems, "Abraham said on 23 July.
The shut-down isn't quite as dramatic(惊人的)as it sounds, experts say. Only two labs will be seriously affected: Sandia National Laboratories in Albuquerque, New Mexico, and Lawrence Livermore National Laboratory in California. Together with Los Alamos, these two labs conduct the most part of the country's nuclear weapon programmes. At Livermore, 876 employees will be suspended during the storage of some 12,000 items of classified removable material.
At other labs, far fewer people will be affected. "The impact (影响) should be the smallest," says Martha Krebs, former director of the energy department's science office.
Why was the storage of classified research at all 24 labs shut down?
A. Because the security problems might be present elsewhere.
B. Because the security problems existed elsewhere.
C. Because two missing computer disks had still not be found.
D. Because officials decided to stop doing such research.
How many labs conduct the country's nuclear weapon programmes according to the text?
A. About 24. B. Only 2. C. More than 2. D. Over 15.
The underlined word "suspended"in the second paragraph probably means "______”.
A. hung from above B. stopped from holding a position C. doubted D. fired
It can be inferred from the text that _____.
A. the computer disks must have been stolen by terrorists
B. the people living in the United States have little security
C. the United States is a country whose security is very bad
D. the missing of the computer disks caused great fear among Americans
【小题1】A
【小题2】C
【小题3】B
【小题4】D
解析:
【小题1】归纳判断题。由第一段后半部分可知,安全问题在别处“可能存在”,而非肯定存在,故排除B。
【小题2】细节判断题。读第五段Together with Los Alamos, these two labs conduct the most part of...可知这个国家不止两个实验室从事核武器的研究。
【小题3】猜测词义题。因接受调查,故停止了他们的工作。
【小题4】推理判断题。一个实验室的电脑磁盘丢失,其他实验室跟着受牵连接受检查,由此可以推断出此事在美国人中间引起了恐慌。其他三个选项太武断,故排除。
Back those photos up
The images were striking. Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions.
If that doesn’t move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos.
Here is a brochure on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad.
Scanning
The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that’s an easy but extremely time-consuming step.
Storing the photos
With your scans in place, import the photos into your computer, and back them up.
You could make multiple copies of the disks and spread them to loved ones. Or you could choose external(外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer.
Online backup
If you need lots of space, look at a pure online backup service, Caronite.
Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer’s main hard drive charges for $59 a year.
Cloud Storage
For folks who don’t need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft’s SkyDrive let you store files online by yourself, share and instantly access them. All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive. But if you want more, you need to pay.
Bottom Line
The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are.

It is common to consider learning as something that takes place in school, but much of human learning occurs outside the classroom, even from birth and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights,sounds,tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics, They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human-service workers need to understand how certain experiences change people’s behaviors. Employers, politicians, and advertisers make use of the principles of learning to affect the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain. Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place and how the brain later outputs knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences.
