C The sequence of infinitives (to begin seriously to study) is awkward and wordy.
D Not almost until is a nonsensical sequence of modifiers. 1. 一般式:not 与until分开,until放在句子的后面。例如:He did not go until midnight. (他直到午夜才走。)
D:Not almost until是modify谁呀?
记得好像高中讲过not until的句型 查了一下
2. 倒装式:not until 连在一起使用,且放在句首,整个句子要倒装。例如:Not until quite recently did I have any idea what a guided missile was like.(直到现在我才知道导弹是什么样子。)
3. 强调式:用于It is + not until +that ...的句型中。例如:It was not until the next day that I learned the truth.(到第二天我才听说事情的真相。)
不知在GMAT中是否还适用
那
C:如果不是be to do 改成
not until almost 1900 did scholars and critics begin seriously to study
是否正确呢?
