OG 3关于until的用法

浅浅123

3. 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


B选项  until后应该用过去时
我想问until后用过去时还是过去完成是有没有相应的规定？

Not do A until do B，也就是说在做B之前都没有做A，直到做B之后才做了A。
所以，唯一能确定的就是do A的时态一定要在do B的时态之后，没有规定until之后一定要用什么时态，这要视not之后的时态而定，只要在其后即可。
