Answer 1

1. D

   not...until...的倒装句型，即：Not until + 时间状语（从句）+ 句子主干/主句（部分倒装）。

   此句正常句序为：He didn't consider having a holiday abroad until he retired from teaching three years ago.

   部分倒装就是把句子的be/助动词/情态动词提到主语之前，类似于一般疑问句的变化。

   AC没有倒装，而且主句为一般过去时，而不是过去完成时，再把B排除。

2. D

   固定句型：It is high time that从句，意思是“到了...的时候了”。

   该句型中要求that从句采用虚拟语气，即从句使用一般过去时或谓语由"should + 动词原形"构成。

   所以答案为：should do 或 did，所以答案D为正解。
