单选题From the ________ shown&n

单选题 From the ________ shown in the dead body, he ________to death by a certain poisonous chemical, but I can’t tell exactly which.A.symptoms; must have been poisonedB.signs; should have been poisonedC.symbols; could have been poisonedD.appearances; may have been poisoned

A解析试题分析：考查推测，symptoms意思“症状”，signs意思“记号”，symbols 意思“象征”，appearances意思“外表”，must have done表示肯定推测should have done表示本应该做某事而没做could/may have done表示没把握的推测，所以选A考点：考查推测点评：注意句子From the symptoms shown in the dead body…,过去分词shown做名词symptoms后置定语，表示被显示的症状。推测是经常考试内容，要加强记忆。
