It has been shown that words having certain connotations (含义) may cause us to react in ways quite foreign to what we consider to be our usual humanistic behavior. (05.6 Passage 1)
分析主干:it has been shown that...
句首It 是形式主语,that 引导的从句作句子的真正主语。主语从句中,主语words后面有一个现在分词短语having...作后置定语;谓语则是“动词(cause)+宾语(us)+补语(to react...)”结构;介词短语in ways...是react 的方式状语。
译文:据表明,具有某些含义的词语可能会使人产生一些反应,而我们认为这些反应是违背我们正常的人性化行为的。
