More Than Just Money
When Patricia Rochester decided to go back to school after ten years as a staff nurse at Toronto Western Hospital, her employer not only cheered her on, but also paid her tuition and gave her a day off with pay every week to study. Throughout her years at the hospital, Rochester has also taken workshops on everything from coaching peers to career development -- courses that she believes have helped her advance at work. "I'm now head of the mentoring （指导） program for new hires, students and staff nurses," she says. "There's a lot of room for personal improvement here."
Perhaps as important, Rochester says her employer supports and values her work. "If you put in overtime," the nurse points out, "you get your meals－they'll order in pizza or Greek food or Chinese." And if staffers feel stiff and stressed from too many hours on the ward, they can call for a free 15-minute shoulder-and-neck massage （按摩） or even sign up for an eight-week evening course on meditation skills and stress-relief. If that's not enough, employees can take advantage of five family days a year that can be used if the kids come down with the flu or an aging parent needs ferrying to an important doctor's appointment. And they have access to a range of perks （好处） such as special rates on hotel rooms, drugstore purchases, and scholarships for employees' children.
You might wonder how an organization can provide such resources and still survive. But University Health Network is one of a number of progressive employers in Canada that have discovered that investing in staff is good business.
If such initiatives help .companies cut down on turnover （人员更替） alone, they're well worthwhile, says Prem Benimadhu, a vice-president at the Conference Board of Canada. It costs anywhere from $3,300 to rehire support staff, an average $13,300 for technical staff and a whopping （巨资） $43,000 for an executive position, according to one study of Conference Board members.
Innovative initiatives help companies attract talented employees, cut down on sick days （which cost Canadian businesses an estimated $17 billion a year, or an average of $3,550 per employee） and keep employees more interested in their work. With the substantial talent shortage that already exists in Canada and the prospect of mass retirement over the next five years－as many as 50 or 60 percont in some sectors-Benimadhu says that intelligent employers are putting a renewed focus on the people who work for them.

"Some" in the last sentence of the first paragraph refers to.
Paragraph 5_______
When Otis came up with the idea of a lift, ________．
Winged robot learns to fly
Learning how to fly took nature millions of years of trial and error-but a winged robot has cracked it in only a flew hours，using the same evolutionary principles．
Krister Wolff and Peter N0rdin of Chalmers University of Technology（CUT） in G0thenburg，Sweden，built a winged robot and set about testing whether it could by itself， without any programmed（预先设定好的）data 0n what napping is or how to d0 it．
To begin with，the robot just twitched and jerked（猛抽）erratically（不稳定地）．But gradually，it made movements that gain height． After it cheated—simply standing on its wing tips was one early short cut． After three hours，however，the robot abandoned such methods in favor 0f a more effective flapping technique，where it rotated its wings through 90 degrees and raised them before twisting them back to the horizontal and pushing down．
“This tells us that this kind of evolution is capable of coming up with flying motion，”says Peter
Bentley，who works on evolutionary computing at University College London． But while the robot had worked out how best to produce lift，it was not about to take off． “There’s 0nlv s0 mach that evolution can do， " Bentley says． “This thing is never going to by because the motors will never have the strength t0 do it，”he says． The robots had metre-long wings made from balsa wood and covered with a light plastic film．
Small motors on the robot let it move its wings forwards 0r backwards，up or down 0r twist them in either direction．
The team attached the robot to two vertical rods，so it could slide up and down． At the start of a test，the robot was suspended by an elastic band． A movement detector measured how much lift．if any，the robot produced for any given movement．
A computer program fled the robot random instructions， at the race of 20 per second． to test its flapping abilities． Each instruction told the robot either to do nothing or to move the wings slightly in the various directions．
Feedback from the movement detector let the program work out which sets of instructions were best at producing lift． The most successful ones were paired up and “offspring" sets 0f instructions were generated by swapping（交换）instructions randomly between successful pairs．These next-generation instructions were then sent to the robot and evaluated before breeding a new generation， and the process was repeated．
第 26 题 Which of the following is NOT true of what is mentioned about the winged robot in the second paragraph？
