例如:阅读文章中有这样一句话:“A survey of new stories in 1996 reveals that the antiscience tag has been attached to many other groups as well, from authorities who advocated the elimination of the last remaining stocks of smallpox virus to Republicans who advocated decreased funding for basic research。”
这句话就是在that引导的宾语从句中,又套入了两个who引导的定语从句。这个句子主句的主体是a survey reveals that…。从句的结构比较复杂:主语是the antiscience tag(反科学的标签),谓语是has been attached to(被贴到),宾语是many other groups,后面用了一个from sb. who…to sb. who…的结构来举例解释这些groups包括什么人。这句话的意思是“1996年进行的一次对新书的调查显示,“反科学”的标签也被贴在了很多别的人群的身上,包括提倡根除残余的天花病毒的权威机构,以及提倡削减基础科学研究资金的民主党人。”
