💡 解题思路
第1题：
“By the time + 过去时”结构中，主句用过去完成时，表示“过去的过去”，故填had。
第2题：
“Not only”置于句首时，主句需部分倒装；此处描述过去事实，助动词用did。
第3题：
先行词为物（the project），且从句缺主语，非限制性定语从句用which引导。
第4题：
对过去情况的虚拟，if条件句用过去完成时（had + 过去分词），此处“had more time”实际指“had had more time”。
第5题：
“Each of + 复数名词”作主语时，谓语动词用单数，故填is。
第6题：
在insist表示“坚持认为（事实）”时，宾语从句用陈述语气；此处指他认为答案“是”正确的，用was。
第7题：
引导让步状语从句，修饰形容词hard，用However（=No matter how）。
第8题：
belong to后接宾格代词，指“属于他”，故填him。
第9题：
“疑问词+to do”结构作宾语，根据句意“做什么”，用what。
