问题 Fossil records indicate________existing in the past have become extinct.

选项 A、that many species of organisms
B、many species of organisms that
C、many species of organisms are
D、there are many organisms

答案 A

解析 化石上的记录表明过去存在的许多生物物种现在已经灭绝了。句子结构题。本句的主干为Fossil records indicate…。indicate后常接that引导的宾语从句。题干中宾语从句的谓语是have become extinct,而且existing in the past是从句主语的后置定语,此从句缺少引导词和主语,故应选A。
