答案解析：
单项选择题
1. D
解析：考察过去完成时，by+过去时间，用过去完成时。
2. B
解析：考察过去完成时的被动语态。后面时间by+过去时间，应用过去完成时，且主语为物，应为被动语态。故选B。
3. D
解析：by+过去时间，用过去完成时。
4. A
解析：考察句型be about to do sth when...，正在做某事突然……。故选A。
5. C
解析：then=at that time，在那个时候，用过去进行时。
6. D
解析：she _______ the head teacher already为She said的宾语从句，主句时态said为一般过去时，所以从句也应为过去时态。其次already出现应用完成式，故为过去完成式。故选D。
7. C
解析：had written为过去完成时，时间状语应为by the end of last year到去年年底前，故选C。
8. C
解析：By the time主句时态为过去完成时，因后有时间段for half an hour，故动词应为延续性动词，begin改为be on。故选C。
9. C
解析：根据时间状语ten years ago可知，时态应为一般过去时，故选C。
10. D
解析：By the time引导从句用一般过去时，主句用过去完成时。根据句意，我把钥匙落在家里是发生在I realized之前，故用过去完成时。forget为忘记，leave sth+介词短语，把落在某地。故选D。
