【例句】1.Ithink(that)mathisdifficult.Shesaid(that)shewouldleaveanoteonthedesk.陈述句作宾语时，宾语从句用____引导。它在只起连接作用，没有实际意义，在从句中不充当任何成分，因此常可省略。that2.Idon’tknowwhether/ifIshouldtakehisadvice.Hewantstoknowif/whetheryouareadoctor.一般疑问句作宾语时，宾语从句用___或whether引导。它们在句子中的意思是______（如果

/

是否）,在从句中不充当任何成分，但不可省略。是否if一般来说，在宾语从句中if与whether可以互换使用。但在特殊情况下，两者不能互换。只能用whether，不能用if引导的情况：1)在介词的后面e.g.I’mthinkingof

whetherweshouldgotoseethefilm.2)与ornot直接连用
