Scientists had been sure the comet was a smooth ball because it follows a smooth path as it orbits the sun. Now they know it looks more like as a potato (彗星在太阳系轨道运转数百万年后，它的坚硬的中心不像专家们认为的那样圆而光滑。科学家曾经肯定地认为它是一个光滑的球，因为当它进入太阳的轨道后沿着一条光滑的轨道运转。现在他们知道彗星更像一个马铃薯)。选项A(彗星像马铃薯，有鳞茎和小洞)为正确答案，而选项B(彗星表面光滑而不像马铃薯)、选项C(彗星表面像专家预期的那样光滑)和选项D(彗星表面有些地方还未被打磨光滑)均不符合题意。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
