Not a single case of T.B. was found in the x-rays studied.
请教老师,not开头的句子的含义?谢谢老师。
这是一种强调说法,意思是“一个……也没有”。又如:
Not a single sound was heard. 一点声音也没听到。
Not a single soldier was killed. 没有一个士兵阵亡。
Not a single sound fell from her lips. 她一个字也没有说。
Not a single person offered to help her. 没有一个人主动出来帮她。
Not a single student in the class got the problem out. 班上无一人解出这道题。
Not a single one of her neighbours gave her any help. 没有一个邻居帮过她忙。
Not a single missile got through the defense system. 没有一枚导弹突破该防御系统。
注:当位于句首的 not a single…不是用作主语时,其后要用倒装语序。中:
Not a single fish did he catch the whole afternoon. 他整个下午一条鱼 也没捕到。
Not a single man did he see on the street in such cold weather. 这么冷的天,他在街上一个人也没见到。

这个句子是名词否定句。主动句如下:

以上二句为名词否定句。
