not until和过去完成时
过去完成时是加在not那边还是until后面
新概念好像写了个
I had not understood the problem until he explained it.
但翻译是
在他解释之前我不懂这个问题
不是说not until是 直到……才吗

not until和过去完成时过去完成时是加在not那边还是until后面新概念好像写了个I had not understood the problem until he explained it.但翻译是在他解释之前我不懂这个问题不是说not until是 直到……才吗
not until:
Not until she had lost her daughter and husband did she realize her true love.知道她失去了女儿和丈夫才发现她的真爱(她本来以为自己不爱她老公,等她老公走了 她发现自己是爱他的)
你那个句子里的NOT 是跟 had连的,i hadn't understood the problem until he explained it.

过去完成时是加在not那边的 hadn't until
until是 直到……为止
