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.

In a 2013 study, it was reported that almost 66 percent of recent high school graduates went to college, a 4 percent decline since 2009, when college enrollment(入学) reached an all-time high.
So, what are the other 35 percent of high school graduates doing after they walk out of their school for the last time? Here are what some Robinson High students have planned.
For Robbie Claiborne, graduation means the start of a military career.He plans to join the Coast Guard after graduation."I was born around the ocean.I love the water.I want to fight for my country and for what I love," said Claiborne.
Others just want a break from school."I really want to take a gap year," Liliam Clavijo said."I'd really love to work in Spain for a year before going to college."
Most students, however, are rather excited.Eban Trunk, a junior, has been planning his future career since middle school."I really want to be a mailman.It just seems like a cool job.Everyone loves the mailman," Trunk said."One day the idea just came to me, and I knew that was what I wanted to do."
For many students, a high school diploma means more choices."I'm not really sure what I'll do after high school," senior Joshua Loring said."I might do technical school.I'm in auto shop classes right now."
Meanwhile, Cassidy Grunderson plans on working at Busch Gardens full time."I just want to live on my own, get a job and move out," Grunderson said.
Stephen Hambleton, who teaches auto tech classes at Robinson, says many of his students choose to enter the automobile industry after graduation."It's an instant job, and after taking years of auto shop in high school, it's easy to get hired," he said.Several seniors in his class, including Loring, plan to enter the industry upon graduation.
"College isn't for everyone, and I really respect people who decide to do their own thing," said Coleman Parks, a senior student."I think too many people feel that they're only as valuable as their degree."

| B．College enrollment in 2013 is not as high as that in 2009. |
