1. A.
   had she considered
2. B.
   did she consider
3. C.
   she considered
4. D.
   she had considered

Answer 1

B
试题分析：考查部分倒装句：Not until引导时间状语从句放在句首时，主句用部分倒装，助动词要提前到主语前面，句意：直到这个女子两个月前再次失业，她才考虑参加培训班。可知是失业后才想起去培训班的，应该是一般过去式。选B。
考点：考查部分倒装句
点评：部分倒装：部分倒装即只把谓语的一部分（如助动词、情态动词等）放到主语前，或把句子的强调成分提前。以否定词开头的句子要求部分倒装。注意下列句子中助动词或情态动词提前、甚至补充助动词的用法：例：Not until yesterday did little John change his mind.（小约翰直到昨天才改变了主意。）
