##### 考题讲解

A选项：Correct. 本选项在语法和逻辑上均是正确的。

waterlogged latex balls and representations of ballplayers attest to the fact.

B选项：首先，证实事实的应是“球”和“画在陶器上的人的表现”。按照本选项所写，动词attest的发出者变为了“球”和“画作”，这里并没有绘画的作品，只有画在陶器上的人。其次，attests是单数，和主语的单复数不匹配。

C选项：并列对象有误，证明了事实的，应该是“水乳胶球”和画在陶器上的人的表现”，不应是“水乳胶球”和“陶瓷器”。陶瓷器本身并不能证明什么，应该是打球人的样子证明着这个ballgame很完善。另外，主谓不一致错误同选项(B)。

D选项：并列对象有误，证明了事实的，应该是“水乳胶球”和“画在陶器上的人的表现”，不应是“水乳胶球的发现”和“画作”。另外，主谓不一致错误同选项(B)。

E选项：发出attest这个动作的，应该是“水乳胶球”和“画在陶器上的人的表现”，不是“发现”。另外，主谓不一致错误同选项(B)。
