    原文定位:

    Last time we began talking about the theory of relativity, which Albert Einstein proposed over a century ago. We said that the formulas and mathematics in Einsteins theory led to predictions that light, rays of light, could be bent by gravity……But here's an example where gravity's involved……Such observations support Einstein's theory that gravity, in this case, the gravity of the sun, affects the path of the light from that star, bends it or curves it. And sort of like that rock you saw in the water, the star appeared to be in a different location from where it actually was.

    选项分析:考察举例考点,教授首先讲到引力会扭曲光,其中就讲了日食的例子,随后表明日食证明引力会扭曲光,让人对恒星的位置感知出现偏差,可知应选C选项。AB选项未提及;D选项仅是文章主旨中的一个例子。
