1 . In a recent meeting, the word “culture” came up 27 times in 90 minutes. Business leaders all believe a strong organizational culture is _________ to success, yet culture tends to feel like some magic force that few know how to control. In our study, we find that answering the following three questions can help transform culture from a mystery to a (n) _________:

How does culture drive performance? After analyzing 50 major companies, we conclude: _________ we work determines how well we work. The companies most famous for their cultures maximize the positive motives(动机), while minimizing the negative ones. Some motives tend to _________ performance. That is because people are no longer thinking about work but the disappointment, or the _________, or why they’re bothering to do it. They don’t _________ the quality of the work itself. By contrast, a high-performing _________ always maximizes creating total motivation.

What is culture worth? While it is _________ to measure whether someone is creative, it’s relatively easy to calculate total motivation of an organization. For example, all airline companies share the same terminals and use the same planes, but customer satisfaction _________ widely across airlines. We found that an airline’s culture closely __________ customer satisfaction. __________, great cultures produced better customer outcomes, and in turn generated more profits.

What elements in an organization __________ motivation? By surveying, we found the most sensitive element is whether an organization can allow an employee to __________ with its mission and behavioral code. For example, An executive of Walmart, told us that in monthly meetings he always emphasized how much Walmart had saved for the __________ — rather than how much money Walmart had made.

A great culture is not easy to build. Leaders have to treat culture building as an engineering project, not a __________ one.

2 . The organic foods have gained a lot of popularity as they are being considered as healthier and tastier. A fair number of people advocate a large-scale shift to organic farming from conventional agriculture. But this might not seem well-founded.

Since the mid-19th century, conventional industrial agriculture has become incredibly efficient on a simple land to food basis. Conventional farming gets more and more crop per square foot of land, which can mean less wilderness needs to be transformed to farmland.

To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer each year, and all that nitrogen(氮) enables much faster plant growth.   However, the cost is paid in vast polluted dead zones at the months of many of the world’s rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment.

To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also   welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices—refusing artificial fertilizers and chemical pesticides—are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion—and people are making those purchases for their moral senses as much as their tongues.

Yet a new meta-analysis in Nature does the math and comes to a hard conclusion: organic farming produces 25% fewer crops on average than conventional agriculture. This is definitely a downside of organic farming, especially when global population is still growing rapidly.

In the Nature analysis, scientists performed an analysis of 66 studies comparing conventional and organic methods across 34 different crop species, from fruits to grains. They found that organic farming delivered a lower output for every crop type, though the difference varied widely. For crops like fruit trees, organic trailed(落后于) conventional agriculture by just 5%. Yet for major grain crops and vegetables—all of which provide the world’s main calories—conventional agriculture outperformed organics by more than 25%.

What that means is that while organic farming may be more sustainable than conventional agriculture, there are trade-offs(此消彼长)with each. So an ideal global agriculture system may borrow the best from both systems rather than upholding merely organic or conventional practices.

10 . As 17-year-old Torri’ell Norwood drove through Florida, last February, the laughter and chatter from the four teenage girls inside her car quickly gave way to screams. As they approached an intersection, another car T-boned them, sending their car sailing into the yard of a nearby home, coming to a stop only when it crashed into a tree.

As smoke rose from the car, a bystander shouted, “It’s about to blow up! Get out!” Shaken, but otherwise OK, Norwood crawled out through the window as the driver’s side door couldn’t be opened. Along with two of her friends, who’d also managed to free themselves, she ran for her life. But halfway down the street, she realized that her best friend, Simmons, wasn’t with them. Norwood ran back and found Simmons unconscious in the back seat. She threw open the back door and pulled her friend out. She dragged Simmons a few feet to safety and laid her on the ground. After checking her pulse and found there was no sign of life, she started CPR.

Had the accident happened a few weeks earlier, she might not have known what to do. But just the day before, Norwood, who wanted to pursue a career in medicine, had earned her CPR certificate by learning on her own. Kneeling on the lawn and looking down at her dying friend, Norwood knew she had precious little time to practice what she’d learned.

She started pumping Simmons’s chest with her interlocked fingers and breathing into her friend's mouth in hopes of filling her lungs with the kiss of life. After quite a while, Simmons began coughing and taking quick deep breaths for air. The CPR had worked! Soon, the ambulance arrived and rushed Simmons to the hospital. And then she heard how her best friend had saved her life. “I wasn't shocked,” Simmons told others. “She will always help any way she can.”
