[不定项选择题]Who should qualify for minimum wage protections, sick leave or any of the other benefits typically given employees? alformia's state Legislature is reopening that high-stakes,decades-long debate, as it prepares to vote on a proposal that would give hundreds of thousands of contract workers, such as drivers of ride haling companies, new benefits by legally relassfyig them as employees. If it passes, the state's narrower definition of "contractor" would trigger a host of other changes for companies that would then have to pay for Social Security, workers' compensation and unemployment insurance. Large employers would also have to pay for health insurance. This would be a significant development in workplace law and could eventually have implications for workers and companies across the country. The proposed change is of keen interest to a rapidly growing population of contractors like Leonardo Diaz. For most of the past 4 years, he has made a decent living working 40 to 50 hours a week driving for the ride-hailing companies. "I love interacting with people," says the father of four, who lives in Los Angeles. But more recently, Diaz has soured on his job. He says that both ride- haling companies cut his share of payments, reducing his take home pay to only $9 an hour,after taking the cost of gas, insurance and car repairs into account. But he says the bigger problem is that he is tired of working as a contractor and misses employee health and paid leave benefits he used to recive when he worked as a valet. "We don't get any holiday pay, "Diaz says. "If we get sick, you know, nobody's going to pay for our doctors," Contractors like Diaz make up a fast-growing part of the workforce. And any company in California using them could be affected. The impact of the new law would reverberate beyond the state. "Everyone is looking to California right now and they're all following it with bated breath because they recognize that likely whatever happens in California is going to sweep across the country," says Monique Ngo-Bonnici, an attorney in California. The proposal expands on a landmark California Supreme Court ruling last year that extended wage protections to more workers and narrowed the definition of "independent contractor." The. legislative proposal expands on that ruling and would give workers benefits like paid sick leave and protections under anti-discrimination laws. Ngo-Bonnici argues that the, California proposal would put big constraints on workers and companies alike. Speically, it would mean more workers will be put on shifts, which in certain municipalities must be scheduled weeks in advance . - - -giving workers far less flexibiliy, she says. One ride-hailing company confirms it would have to revamp its operations in the state drivers are redassified as employees." We would need far fewer drivers than we currently have."says Adrian Durbin, a company spokesman. And those that remained would have a much more rigid work schedule. Durbin says those Big companies pushed California lawmakers for a middle ground that would grant independent contractors a narrower set of benefits, like minimum wage guarantees, without making them ullledged employees. What can be the best title of the report?
A.The Rise of Contract Workers: More Benefits Aro Needed.
B.Contract Work with Benefits: Califormnia Might Provide a Model
C.The Dilemma of Gig Economy: More Workers but Fewer Benefits.
D.The Future of Benefits: More Efforts for Legislation on Contract Workers

[不定项选择题]共用题干 Sleeping

People who sleep for more than eight hours a night do not live as long as those who
sleep for six hours,according to the biggest study yet into sleep patterns and mortality（死
亡率）.
Scientists have no explanation for the findings and do not know if they mean people who
like a lie-in（睡懒觉）can extend their lives by sleeping less.
Although it is a common belief that sleeping for at least eight hours a night is vital for
health and well-being,the six-year study involving more than 1.1 million Americans older
than 30 found that those who slept for less than eight hours were far from doing themselves
any long-term harm.
"Individuals who now average 6.5 hours of sleep a night can be reassured that this is a
safe amount of sleep.From a health standpoint,there is no reason to sleep longer,"said
Daniel Kripke , a professor of psychiatry（精神病学）at the University of California, San
Diego.
Dr. Kripke said,"We don't know if long sleep periods lead to death.Additional studies
are needed to determine if setting your alarm clock earlier will actually improve your health."
The scientists,who were funded by the American Cancer Society,found that the best
survival rates were among the men and women who slept for seven hours a night.Those
who slept for eight hours were 12 per cent more likely to die during the six-year period of the
study,when other factors such as diet and smoking were taken into account.
Even those who spent a mere five hours a night in bed lived longer than those who slept
eight or more hours.However,an increasing death rate was found among those who slept
for less than five hours.
Dr. Kripke said,"Previous sleep studies have indicated that both short-and long-duration
（持续时间）sleep had higher mortality rates. However, none of those studies were large
enough to distinguish the difference between seven and eight hours a night,until now." The study was the first to tell the difference between 7 and 8 hours of sleep a night.

[不定项选择题]共用题干 Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker （修补）with machines in the lab and write computer software to control these devices.
“They're the best toys out there,” says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist,a person who designs,builds or programs robots.
When Choset was a kid,he was interested in anything that moved一cars,trains,animals. He put motors on Tinkertoy cars to make them move. Later,in high school,he built mobile robots similar to small cars.
Hoping to continue working on robots,he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena,Choset's lab- mates were working on something even cooler than remotely controlled cars:robotic snakes. Some robots can move only forward,backward,left and right. But snakes can twist（扭曲）in many directions and travel over a lot of different types of terrain（地形）.“Snakes are far more interesting than the cars,”Choset concluded.
After he started working at Carnegie Mellon,Choset and his colleagues there began developing their own snake robots.Choset's team programmed robots to perform the same movements as real snakes,such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling. Choset's snake robots could crawl（爬行） through the grass,swim in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries,the doctor has to open a patient's chest,cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?
Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot in pigs.
A company called Medrobotics in Boston is now adapting the technology to surgeries on people.
Even after 15 years of working with his team's creations,”I still don't get bored of watching the motion of my robots,”Choset says. The robotic technology for surgeries on people has brought a handsome Medrobotics.
