直到经理来我们才讨论。 We didn't stop working until the manager came.
直到经理来我们才停止工作。
当until意为“直到……才”时,主句就要用否定 句,而不是依据主句的动词是否是延续性动词。
当主句是延续性动词时,主句用肯定句,其意思 是:主句的动作一直延续到从句动词所发生的动 作为止;
使用否定句时,则表示从句的动作发生时,主句 的动作才开始发生。
(3)until后的时态问题
由于until引导的是时间状语从句,所以它的一般 将来时用一般现在时代替;过去将来时用一般过去时 代替;将来完成时用现在完成时代替。
He had left his key in the office. He had to wait
until his wife came.
Don't get off the bus until it has stopped.
(4) 这一句式的倒装问题
当not until在句首时,其主句应当使用倒装句; 而强调句则不倒装。
Not until he came back from Africa that year did he
meet the girl he would like to marry.
It was not until he came back from Africa that year
that he met the girl he would like to marry.
