关于OG12 第三题引出的副词位置的疑问

mcsimon

一直搞不清楚副词应该在句子中摆在什么样的位置，于是今天百度了一下，发现一个比较不错的解释。原帖如下。

副词可以修饰动词，形容词，副词。副词的位置很灵活，在一个句子中副词可以放在句首，句中，句末。具体如下：1、一般副词都是放在谓语动词后面。2、程度副词通常放在所修饰词前。如：The problem is too difficult.(too, 就是程度副词）注：程度副词enough通常放在形容词或副词的后面3、频度副词（often，always,never,seldom等）通常放在行为动词前面，系动词，助动词，情态动词的后面。所以你说的run quickly是正确的，但是quickly run就是不正确的了。quickly是一个一般的副词，放在动词后。


然后看到OG12 第三题有点感悟
Although various eighteenth- and nineteenth-century
American poets had professed an interest in Native
American poetry and had pretended to imitate Native
American forms in their own works, until almost 1900,
scholars and critics did not begin seriously to study
traditional Native American poetry in native languages.
?? (A) until almost 1900, scholars and critics did not begin
seriously to study
?? (B) until almost 1900 scholars and critics had not begun
seriously studying
?? (C) not until almost 1900 were scholars and critics to
begin seriously to study
?? (D) it was not almost until 1900 when scholars and
critics began to seriously study
?? (E) it was not until almost 1900 that scholars and critics
seriously began studying
在这里根据逻辑意思可知seriouly修饰动词begin,而seriouly作为程度副词应置于begin之前，如上可直接排除ABCD选项。
以上纯属自己闲着没事瞎想着玩，不知道这种方法靠不靠谱常不常见。。。

布布布布布丁

疑问 那D选项的not almost until作何解释呢
