Part Two 体会音变 You can tell the age of ˆa tree by counting its rings, but these records ˆof trees’ life really say a lot more. Scientists ˆare using tree rings to learn what’s been happening on the sun’s ˆsurface for the last ten thousand years. Each ring represents ˆa year of growth. As the tree grows, it ˆadds ˆa layer to its trunk, taking ˆup chemical elements from the air. By looking ˆup the elements ˆin the rings for a given year, scientists can tell ˆelements were in the air that year, Doctor Stevenson is analyzing one ˆelement－carbon-14 in ring from both living and dead trees. Some ˆof the rings go back almost ten thousand years to the end ˆof the Ice ˆAge. When Stevenson followed the carbon-14 trail back ˆin time, he found carbon-14 levels change with the intensity of solar burning. You see, the sun has ˆcycles. Sometimes ˆit burns fiercely and ˆother times it’s relatively calm. During the sun’s violent periods, it throws ˆoff charged ˆin fast moving streams called solar winds. The particles interfere with the formation ˆof carbon-14 on ˆearth. When there’s more solar wind activity, less carbon-14in produced. Ten thousand years ˆof tree rings show that the cardbon-14 level rises ˆand falls ˆabout every 420 years. The scientists concluded that the solar wind activity must follow the same cycle.
