Question

【题目】It was not until I went through his paper that __________ what rapid progress he had made in writing.

A. had I found B. did I find

C. I had found D. I found

Answer 1

【答案】D

【解析】句意:直到我浏览了他的试卷我才发现他的书写取得了多么大的进步。考查特殊句式。此题为特殊形式的强调句型，同时考查时态。以下形式都正确：

1 didn't find what rapid progress he had made in writing until I went through his paper. ( not. . . until…直到……才……)

Not until I went through his paper that did I find what rapid progress he had made in writing, (not until 位于句首，主句要部分倒装）

It was not until I went through his paper that I found what rapid progress he had made in writing。 (含有 not until 的强调句型）
