Chapter 1 身体・病気と健康 身体・病気と健康 [1] 3 ferocious attacks of zoonoses, animal infections that can be transmitted to humans. Being new to people, the germs often caused far worse symptoms 1 滋賀医科大 than those in their usual hosts. Therefore, any deadly human infection should be suspected of being recently acquired by our species. 1 ☆★ From Man and Microbes: Disease and Plagues in History and Modern Times by Arno Karlen, Tarcher 目標20分 注 savanna: サバンナ yellow fever predator 次の英文を読んで、下の設問に日本語で答えよ。 ("印の語には注がある。) The first big shock to influence human disease patterns was our ancestors' descent from the trees to the ground, about five million years ago. Perhaps this happened when Africa became drier, and savannas" replaced forests. This descent brought changes in our ancestors' diet, lifestyle, and burden of disease. As a species with our feet now firmly on the ground, we tend to think of territory horizontally. However, every environment has significantly different vertical zones. In a forest, certain species of mammals, birds, and insects require the sunlight and food in the leafy treetop layer; others need the shade, moisture, and food on the ground; several intermediate zones may exist between earth and treetops. Moving its usual location only a few meters can radically alter a species' prey, predators, and germs. Today, for example, we often see diseases invade new vertical zones. In Central and South America, mosquitoes infect treetop monkeys with the yellow fever virus. The disease remains isolated in the top forest layer because monkeys and mosquitoes there rarely travel lower. The commercial demand for tropical timber has sent loggers into the forests, and when they cut down a tree, clouds of mosquitoes come to earth with it. The mosquitoes then feed on the warm-blooded animals nearest at hand, the loggers, and transmit the virus. On returning home to cities, the infected workers set off urban epidemics of yellow fever. After our ancestors' descent to the ground exposed them to new diseases, the change in their diet from plant protein to include meat, as they became hunters, brought about another change in disease burden over the next tens or hundreds of thousands of years. In each new ecosystem, travelling hunters met new prey, new vectors (disease carriers), and new parasites*.

次の英文を読んで,下の設問に答えなさい。 Last year, 4.2 million babies died. That is the most recent number reported by UNICEF of deaths before the age of one, worldwide. We often see lonely and emotionally charged numbers like this in the news or in the materials of activist groups or organizations. They produce a reaction. Who can even imagine 4.2 million dead babies? It is so terrible, and even worse when we know that almost all died from easily preventable diseases. And how can anyone argue that 4.2 million is anything other than a huge number? You might think that nobody would even try to argue (that, but you would be wrong. That is exactly why I mentioned this number. Because it is not huge: it is beautifully small. If we even start to think about how tragic each of these deaths is for the parents who had waited for their newborn to smile, and walk, and play, and instead had to bury their baby, then this number could keep us crying for a long time. But who would be helped by these tears? Instead let's think clearly about human suffering. The number 4.2 million is for 2016. The year before, the number was 4.4 million. The year before that, it was 4.5 million. Back in 1950, it was 14.4 million. That's almost 10 million more dead babies per year, compared with today. Suddenly this terrible number starts to look smaller. In fact (2)the number has never been lower. Of course, I am the first person to wish the number was even lower and falling even faster. But to know how to act, and how to prioritize resources, nothing can be more important than doing the cool-headed math and realizing what works and what doesn't. And this is clear: more and more deaths are being prevented. comparing the numbers. (3). We would never realize that without
