题目内容
Not until the teacher explained the importance of getting up early ______ we promise to come early.
A.should | B.would | C.did | D.could |
C
解析试题分析:句意:直到老师向我们解释了早起的重要性,我们才答应会早点来。Not until置于句首时,句子要部分倒装,部分倒装将be动词或是do/does/did提前,本句中将did置于主语前面,故选C
考点:倒装
点评:英语中倒装分为部分倒装和完全倒装,当否定副词置于句首时,句子要部分倒装。部分倒装即只把谓语的一部分(如助动词、情态动词等)放到主语前,或把句子的强调成分提前。在部分倒装句中,只有助动词、情态动词或连系动词to be可以置于主语之前,其它部分都要置于主语之后。
