问题
Not until recently, ________the cause of the disease.
选项
A、these scientists found
B、these scientists did find
C、found these scientists
D、did these scientists find
答案
D
解析
本题考查部分倒装的用法。在含有Not…until… 的句子中,当Not until位于句首时,主句要用部分倒装,即“助动词+主语+谓语动词”的形式。D项是“助动词did+主语these scientists+谓语动词find"的结构,故为答案。倒装语序有两种:一种是完全倒装,即将谓语动词置于主语之前。例如,“Here comes the bus!”和 “There is a very famous bar. ”。另一种是部分倒装,即将谓语的一部分(通常是助动词、系动词或情态动词)置于主语之前。例如,一些含有否定意义的词或短语位于句首时,包含该词或短语的句子通常使用部分倒装,如“Never have I read such an interesting book. ”。常见的这类词(短语)有never、seldom、rarely、little、hardly、scarcely、no sooner、no longer、nowhere等。A项和B项不是倒装结构,C项是全部倒装结构。
