Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza — for their work on how cells sense and adapt to oxygen availability. The Nobel Assembly announced the prize at the Karolinska Institute in Stockholm on Monday. Their work established the genetic mechanisms(機制) that allow cells to respond to changes in oxygen levels. The findings have implications(啟示) for treating a variety of diseases. Why did they win? Oxygen is the lifeblood of living organisms(生物體), said Dr. George Daley, dean of Harvard Medical School. Without oxygen, cells can39。t survive. But too much or too little oxygen can be deadly. The three researchers tried to answer this question: How do cells regulate their responses? The investigators uncovered detailed genetic responses to changing oxygen levels that allow cells in the bodies of humans and other animals to sense and respond to fluctuations(波動), increasing and decreasing how much oxygen they receive. Why is the work important? The discoveries reveal the cellular mechanisms that control such things as adaptation to high altitudes and how cancer cells manage to hijack(攫取) oxygen. Randall Johnson, a member of the Nobel Assembly, described the work as a textbook discovery and said it would be something students would start learning at the most basic levels of biology education. This is a basic aspect of how a cell works, and I think from that standpoint alone it39。s a very exciting thing. Johnson said. The research also has implications for treating various diseases in which oxygen is in short supply — including anemia, heart attacks and strokes — as well as for treatment of cancers that are fed by and seek out oxygen.（1）This research has won the Nobel Prize mainly because ____________.

They took a % part together of the total global new leaf area between 2000 and 2017. China played a major role, adding 25% to this increase, and India added %, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than million square kilometers of green leaf area was added globally. Since 2000, there has been a fivepercent increase in global green cover, it said. The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest, Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability. Large plantation activities to protect forests in China contributed nearly 42% to the country39。s green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture. China and India take up onethird of the greening, but hold only nine percent of the planet39。s land area covered in green plants, Chi Chen told NASA Earth Observatory. That is a surprising finding, considering the land degradation(退化) in countries with large populations. Boston University39。s research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase. Finally, with the help of NASA39。s Terra and Aqua satellites research, they managed
