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

为什么说C选项中的to begin seriously to study是awkward and wordy?

米祈

C是倒装，正常语序是scholars and critics were to begin seriously to study not until almost 1900
其实 scholars and critics began seriously to study not until almost 1900
were to 实在没有必要啦
