部分倒装就是助动词提前到主语前：其实,就象一般疑问句一样结构.助动词+主+谓语+……be(是）在这里不是助动词,但可以当作助动词用have是“有”的意思时,也可以当助动词用.如So many books do you have that I don't ...为什么可以当助动词用呢？这里is既是助动词又是系动词？不是助动词，但可以象助动词一样充当否定（加not)、疑问（提前到主语前）如：He is a student.He isn't a student.Is he a student?She has a brother.She hasn't a brother.She doesn't have a brother.Has she a brother?=Does she have a brother?(have“有”时，可以直接加not，也可以用do,does来做助动词。
