网考网解析：
辨认事实题。题目询问作者认为当今最先进的计算机怎么样。根据文章第1段“But as useful as computers are，they're nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior．Never mind something as complex as conversation：the most powerful computers struggle to reli- ably recognize the shape of an object(但是尽管计算机的用途已非常广泛，它们仍然不能像早期研究者预言的那样进行与人类相似的活动，更不用说进行复杂的交流活动。最先进的计算机连正确地辨认一件物体的形状都很困难)”，故[D]正确，[A]和[B]与文中意思相背；[C]与事实不符。 查看试题解析出处>>
