2. The movement of the moon conveniently provided the unit of month, which was _____ from one new moon to the next. 空格处答案是reckoned，如果填measured合适吗？

3. The mayor is a woman with great _____ and therefore deserves our political and financial support. 空格处答案是integrity，如果用intention，表示“很好的想法或愿望”可不可以？

4. She felt suitably humble just as she _____ when he had first taken a good look at her himself, hair waved and golden, nails red and pointed. 空格处答案为had，为什么不用had felt？
