24、我们把握住两者使用时本身的含义及主句动词是终止性（非延续性动词）的，还是延续性的，肯定式，还是否定式两大点，就能容易地解决这类问题。现详细阐明如下： 一、在下列情况下，两者可互换用，但含义略有不同。before表示“在之前”的意思，强调时间先后关系；而until表示“直到才”的意思，主句是肯定句则表示主句动作的终止时间；从句是否定句则强调主句动作的起始时间。 1.主句为否定式终止性谓语动词。常见的动词open, start, leave, arrive, finish,stop等。例如： (1)The noise of the street didnt stop until/before it

25、 was midnight. (2)The children wont come back until/before it is dark.

(2)I will wait until/before he comes to

26、my help. (3)I shall stay heer until/before you come back. 二、在下列情况下，用before不用until。 1.主句这肯定式、终止性谓语动词，只用before。例： (1)He fell asleep before I could take off his clothes. (2)We arrived there before it atarted to rain. (3)The holiday came to the end befor I knew it. (4)He almost knocked me down before he

27、 saw me. 2.主句谓语动词强调动词的迟缓性，只用before，常伴有时间段状语或时间段暗示。例： (1)It was quite some time before he found the elephant at all. (2)We had walked a long way before we found some water. (3)We had sailed for two days before we saw the land. (4)The fire lasted about four hours before the firefighters could countrol it. (5)It was midnight before my brother came home.
