The two scholars worked at the task of writing a preface to the new dictionary for three hours____last night.

She said she wouldn't call us the next day,_____she?
A would
B wouldn't
C did
D didn't
正确答案是D，请教一下各位为什么呢？
多谢！
可是第二题从句不转换么。。

1. 可以用排除法，c项是最终用三个小时…… a 表达长度， b 完全地 d及时,都不符合题意

2. 在做反意疑问句时，针对的是主句，此句中，主句的动词为said,因此用助动词did

1.on end 连续地（不是最终）
2.如果主句主语是第一人称，反义疑问句是对从句进行反问；如果主句主语不是第一人称，翻译疑问句对主句进行反问。

二楼的解释是正确的

at length:
1.if you talk at length about sth.,you talk about it for a long time.长时间地
2.after a long time.uihou，最后，最终

in full
1.if you pay an amount of money in full,you pay the whole amount（付款）全数地，全部地
2.if you write or copy sth. in full,you write it in its complete form全文地，完整地，详细地

on end
consistently连续地

in time
1.early or soon enough to do sth.及时（做某事）
2.after a certain period of time,especially after a gradual process of change and development过一段时间，迟早

参考 《朗文当代高级英语辞典》

反义疑问句，主句用肯定，则后面疑问部分用否定，反之则用肯定。
