英语倒装句的选择题求解释,满意秒采纳Not until I came into the classroom（）her illnessI had realizeddid I realizehave I realizedI realizeI realized
网友回答
not until 否定开头所以要倒装排除所有没到装的只剩两个did I realize和have I realized
由于时态是过去式所以选did i realize
======以下答案可供参考======
供参考答案1:
did I realize
.在英语中，否定词开头，主句用倒装。 例如：
Little did I know about it. 我对此几乎什么也不知道。
Never have I been to the Great Wall. 我从来没有去过长城。
供参考答案2:
Not until引导的句子要倒装，由于是一般过去时，所以选择did I realize
