书上的没错.第二个是正确的啊.not……until是“直到……才……”.直到他完成作业我们才去打扰他.也就是说,打扰他发生在完成作业之后,那么句中finish用的是过去式finished,而“打扰”是过去的过去,应该用过去完成时,had +动词过去分词

没错啊

第二个正确啊

第2个是错的
第2个句子出现在新概念二册的14课,如果你买的是2011年7月第97次印刷版本之前的版本,书上写的恰好就是第2个句子。
但是后来的版本是更正了的,因为not...until 是 直到...才... 的意思,比如 I didn't have supper until 10p.m. 翻译过来是我直到10点才吃晚饭 而不是 我直到10点都还没吃晚饭。
所以当用NOT...

所以当用NOT UNTIL 引导过去完成时的时候,UNTIL 后面接的动作(动1)要先于 NOT 后面接的动作(动2)发生,因为只有直到动1发生了,动2才发生,所以动1是先于动2的,所以动1我们用过去完成时。参见:http://zhidao.baidu.com/question/346119990.html
