16．How do you design a pay plan that motivates people to do their best work？A new study by three Harvard researchers suggests a novel answer：Shortly after you hire new workers，give them a raise．
"Previous research has shown that paying people more than they expect may elicit reciprocity（相互作用） in the form of greater productivity，"notes Deepak Malhotra，a Harvard business-administration professor who worked on the study．What he and his colleagues found，however，was that the connection between more pay and extra effort depends on presenting the increase"as a gift-that is，as something you've chosen to do purely as a nice gesture，with no strings attached．"
Malhotra and his team studied 267people hired by oDesk，a global online network of freelancers，to do a one-time data-entry project for four hours．All of the new hires were people in developing countries，for whom hourly wages of 3and4were higher than what they had been making in previous jobs．
The researchers split the group up into three equal parts．One group was told they would earn 3anhour．Asecondgroupwasinitiallyhiredat3an hour but，before they started working，they got a surprise：The budget for the project had expanded unexpectedly，they were told，and they would now be paid 4anhour．Thethirdgroupwasoffered4an hour from the start and given no increase．
Even though the second and third groups were eventually paid the same amount，the second group worked harder and produced more-about 20% more-than either of the other two．People in the second group also showed the most stamina，maintaining their focus all the way through the assigned task and performing especially well toward the end of the four hours．Interestingly，the more experienced employees in the high-performing group were the most productive of all，apparently because their previous work experience led them to appreciate the rarity of an unexpected raise．
Contrary to conventional wisdom，Malhotra points out that higher pay，in and of itself，didn't promote productivity：People who made 4anhourfromthebeginningworkednoharderthanthosewhowerehiredat3and were then paid $3．
To get the most impact from their pay plans，he adds，companies might consider not only what to pay new hires，but when to pay it．
"The key thing is how you present[the reason for an increase]，"he says．Doling out extra money could promote productivity most"if you make it clear that the pay raise is something you're choosing to do just because you can．Our theory is that people will reciprocate．If you do something nice，they'll do something nice back．"
59．What does the underlined word"stamina"most probably mean？C
A．The quality of being intelligent or clever．
B．The quality of doing something difficult or dangerous．
C．The physical or mental energy needed to do a tiring activity for a long time．
D．A particular method of doing an activity，usually involving practical skills．
60．Why did the second group produce more than the other two groups？D
A．Because they thought they were better paid than the other groups．
B．Because they were experienced employees from developing countries．
C．Because an unexpected raise reminded them of their previous work．
D．Because they felt they were nicely treated and tried best to repay it．
61．What can we infer from this passage？B
A．No pains，no gains．B．It matters not what we give but how．
C．Honesty is the best policy．D．Actions speak louder than words．

3．Health experts are calling for action to expand cancer care and control in the developing world．A medical research paper says cancer was once thought of as a problem mostly in the developed world．But now cancer is a leading cause of death and disability in poor countries as well．Experts from Harvard University and other organizations ask the international community to fight cancer positively，saying it should be fought in the way AIDS has been fought in Africa．
Cancer kills more than 7.5 million people a year worldwide．Almost two-thirds are in low-income and middle-income countries．
They discover cancer kills more people in developing countries than AIDS，tuberculosis （肺結(jié)核） and malaria （瘧疾） combined．But the world spends only 5% of its cancer resources（資源） in those countries．
Felicia Knaul from Harvard Medical School was one of the authors of the paper．She was in Mexico when she was found to have breast（乳腺） cancer．She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer．
Felicia Knaul says，"And we are seeing how this is attacking young women．It's the number two cause of death in Mexico for women thirty to fifty-four．All over the developing world，it's the number one cancer-related death among young women．I think we have to again say that there is much more we could do about it than we are doing about it．"
Professor Knalul met community health workers during her work in developing countries．They were an important part of efforts to reduce deaths from the cancer．They were able to persuade people to get tested to prevent the illness．The experts say cancer care does not have to be costly．For example，patients can be treated with lower-cost drugs．
