A．A Successful Training Program
B．How to Describe and Specify a Job
C．Staff Training
D．The Importance of Training Workers and Technicians
Amazingly, these happy times appear still to be with us in the world's biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home Without fitting locks to their doors.
SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle.
But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.
So is the Net becoming more secure？ Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do, all kinds of nasty things to your computer.
At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial ,people who want to invade weak sites and cause damage.
But let's look on the side. Given the lack of locks, the Internet is surely the world's big gest(almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn't much to steal. Or because vandalism isn't much fun unless you have a peculiar dislike for someone.
Whatever the reason, let's enjoy it while we can. But expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling services they want to be paid for.
By saying"...owners of well over half of all World Wide Web sites have set up home with out fitting locks to their doors" (Line 3-4, Para.2), the author means that______.
A．those happy times appear still to be with us

Passage Two Questions 27 to 31 are based on the following passage.
Sixteen-year-old Karlos Dearman’s future is looking much brighter than he might previously have imagined. “I’ve always been into bikes, but never thought I’d end up working with them,” he says. “This scheme has changed my life.”
Karlos is learning to refurbish (翻新) old bicycles in the workshop of ReCycle Bikes, a local community charity in Sheffield, which has a contract with the city council to provide training opportunities for young people aged 14 to 16, particularly those struggling in mainstream education or excluded from school.
“It’s about engaging youngsters with education and youth training by teaching them work and life skills,” explains Des Pearce, workshop training manager. “These young people have so much potential, but often don’t realize it.”
Established in 2001, ReCycle Bikes repairs bicycles donated by the public, which, once restored, are sold for ￡20. Abandoned bikes supplied by the council ensure a steady flow of bikes, but a recently formed partnership with Sheffield University should improve further the prospects of the young mechanics.
“The student population presents a large and ready market,” says Pearce. “So we approached the university last year and offered to host bike sales on the campus. They thought it was a great idea, and agreed to supplement our council funding. This means we can train youngsters to repair extra 500 bikes over three years, and fund Karlos’s apprenticeship.”
Having set up ReCycle Bikes on his own, Pearce now has the staff and resources to track the career development of those who have passed through his workshop.
“At the moment we depend on anecdotal evidence from the schools,” he says. “But we are planning exit interviews with the young people to ascertain what they plan to do, and these will allow us to check on their progress.”
That most of the teenagers enjoy the work is, according to Pearce, easily explained. “Most kids have ridden a bike and know how to oil a chain or mend a puncture. As low-cost transport, cycling gives the young and old a sense of freedom and independence, and the impact on their well-being is immense. Add to that a growing concern for the environment, and it’s no surprise that bike sales are on the increase.”
