Passage 6 The Sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its centerthat convert hydrogen to helium. The Sun has existed in its present state for about 4 billion, 600million years and is thousands of times larger than Earth. By studying other stars, astronomers can predict what the rest of the Sun’s life will be like.About 5 billon years from now, the core of the Sun will shrink and become hotter. The surfacetemperature will fall. The higher temperature of the center will increase the rate of thermonuclearreactions. The outer regions of the Sun will expand approximately 35 million miles, about thedistance to mercury, which is the closest planet to the Sun. The Sun will then be a red giant star.Temperatures on the Earth will become too hot for life to exist. Once the Sun has used up its thermonuclear energy as a red giant, it will begin to shrink. After itshrinks to the size of the Earth, it wil A. To alert people to the dangers posed by the Sun. B. To discuss conditions on Earth in the far future. C. To present a theory about red giant stars. D. To describe changes that the Sun will go through. 我来回答: 提交
