高三英语，求解一道选择题
was until, when B. was until, that
C.wasn’t until, when D. wasn’t until, that
这道题为什么是A，为什么是when，不是强调句吗？was until和wasn’t until的区别？ 展开
It ______ we had stayed together for a couple of weeks ______ I found we had a lot in common.（2007浙江）
.A. was until ;when B. was until; that C. wasn't until;when D. wasn't until;that
答：D
译：直到我们一起呆了几个星期之后我才发现我们原来有那么多的共同之处。
析：原以为你题没打完整，是一个陷井题，却原来是参考答案错了。
我教学生记背三个相关句型：
He didn't go to bed until 12 o'clock last night. （not until 句型）
Not until 12 o'clock that he went to bed last night. （倒装句）
It was not until 12 o'clock that he went to bed last night.（ 强调句）
PS：请注意带有限制性定语从句的强调句之省略题（很大的一个陷井！）
如：--Where did you meet Yaoming?
-- It was in the hotel 【where】 my father worked ten years ago.
如果单独看第二句，是一个常见的错误的强调句（我们提醒学生，强调句，不论强调的是主语、宾语还是状语，也不能主语、宾语指的是人还是事物，一律可用it is/was ... that...., 我们强调，如果强调的是状语时，一定不要用where 和when, 后面三个二级同学注意了！)。这个where改成that才是一个标准正确的强调句：
It was in the hotel 【that】 my father worked ten years ago.
但这里如果你真that就错了，因为答非所问。
原来这是一个省略了的强调句。更是一个不必经的强调句!
如果不省略，则为：
：--Where did you met Yaoming? 你在哪里巧遇姚明的？
-- It was in the hotel 【where】 my father worked ten years ago that I met Yaoming.
我是在我父亲十年前工作过的那家宾馆遇到他的。
如果不强调，也不省略，直接回答：I met him in the hotel 【where】 my father worked ten years ago.
如果省略则为：In the hotel 【where】 my father worked ten years ago.
was until和wasn't until的区别?
这也是not... until 句型的强调状语时应注意的问题。
sb. didn't do A until B happened. 之强调时间状语不是：
it was until B happened that sb. didn't do A. 而是
it was not until B happened that sb. did A.
为什么是这样？没想过。所以我让学生记三个句型。
如是肯定句，则照常如: Tom stayed up until his father came back at 12 o'clock last night.
强调状语:it was until his father came back at 12 o'clock that Tom stayed up last night.
这时，until从句前的主句的谓语动词必须是延续性动词。如果你问，为什么不能选B，则告诉你，find非延续性动词。
绝对不会是A请相信 我。
就是 强调句型 不能用when 只能用that
正常语序是 I didn't find we had a lot in common until we had stayed together for a couple of weeks
倒装句是 not until we had stayed together for a couple of weeks did I find we had a lot in common.
强调句型是It wasn't until we had stayed together for a couple of weeks that I found we had a lot in common.
stay是可延续动词 就用肯定形式
not until “直到···才”
until“直到….为止”
