有趣的长难句27
昨天的正确答案是C，小伙伴们答得顺利吗？昨天的题目具有一定的迷惑性，主旨句里的主语是“最早的生物”，却用两个定语从句强调了系动词之后的内容“共生的例子”，所以有人会错误地把“共生”作为主旨单独拎出来考虑。因此，在考虑长难句时，确定主旨里的主语非常重要。至于用"the first organisms"来替换“the earliest living things”的方法，我们在7月26日《有趣的长难句13》里曾经遇到过一次，那次是将“begins with”改写成 “the first step”，这种改写方法已经是第二次出现。
今天的题目选自《Chinese Pottery》，关于陶器，我理解的几个名词大致是pottery是总称，ceramic分为三个部分：earthenware、stoneware和porcelain，这大概是从制陶技术方面分类的。至于chinaware或china应该外国人对中国陶瓷的专称。今天的题目有些复杂，不仅是句式还是指代，都不是非常明确，是我最头疼的类型。

A. While stonewares and porcelains are found throughout most historical periods, religious sculpture is limited to the ancient period.
