问题 Not until quite recently______ any idea of what a guided rocket is like.

选项 A、did I have
B、do I have
C、should I have
D、would I have

答案A

解析 本题考查的是倒装句。否定词或含有否定意义的词置于句首时,句子都要部分倒装。这类词有:never,hardly,seldom,not only…but also,neither…nor,hardly…when等。本题中的not until是否定词且处于句首,所以句子需要借助于助动词进行部分倒装。recently的意思就是not long ago“不久前,近来”,应用一般过去时,因此A项为正确答案。
