2015青岛二模英语试题及答案(2)

    I kept smiling at him, now thinking of him as a person and not just a guard. "Do you have kids?" he asked. “Yes, here, here.” I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes filled with tears. I said that I feared that I’d never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the prison, quietly and by back routes, out of the town. There, at the edge of town, he released me. And without another word, he turned back toward the town.

    Some people think if you are happy, you are blind to reality. But when we research it, happiness actually raises every single business and educational outcome for the brain. How did we miss this? Why do we have these social misunderstandings about happiness? Because we assumed you were average. When we study people, scientists are often interested in what the average is.
    Many people think happiness is genetic. That’s only half the story, because the average person does not fight their genes. When we stop studying the average and begin researching positive outliers —people who are above average for a positive aspect like optimism or intelligence —a wildly different picture appears. Our daily decisions and habits have a huge impact upon both our levels of happiness and success.
Scientifically, happiness is a choice. It is a choice about where your single processor brain will devote its limited resources as you process the world. If you scan for the negative first, your brain really has no resources left over to see the things you are grateful for or the meaning embedded(嵌入) in your work. But if you scan the world for the positive, you start to acquire an amazing advantage.
    I wrote the cover story for the Harvard Business Review magazine on “Happiness Leads to Profits.” Based on my article called “Positive Intelligence” and my research in The Happiness Advantage, I summarized our researched conclusion: the single greatest advantage in the modern economy is a happy and busy workforce.
A decade of research in the business world proves that happiness raises nearly every business and educational outcome: increasing sales by 37%, productivity by 31%, and accuracy on tasks by 19%, as well as a number of health and quality-of-life improvements.

D. Our decisions and habits have nothing to do with happiness.

Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human-to-human contact. The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength. This virus is responsible for the current outbreak in West Africa. They found that initially the animal systems were not affected by the virus, but succeeding transmission(传送) into other animals caused the virus to “hot up” and become more severe.
    The team analyzed the viruses at different stages and were able to identify several changes in its genetic_w_3 material that were associated with increased disease.
