not until放在句首是什么意思?
Not until they found no signs of life did rescue workers stop their efforts

not until (.) 是强调在(.)之前的事情.而且后面的句子一定要倒装.
这个句子的意思:在他们没有核实无生命体征之前,一直没有放弃救援工作.

恢复语序就清楚了
Rescue workers didn't stop their efforts until they found no signs of life.
直到没有发现生命迹象,救援人员才停止搜索工作。
not unitl提前后面要到装。

直到他们没有发现生命的迹象时,救援人员停止他们的努力。
