32. It wasn't until two o'clock that I _______ to sleep.
A would go B went C was going D had gone 答案b为什么不选d请给出详细的解析谢谢

Answer 1

这里用的是until的强调句型，它相当于“I went to sleep when it was two o'clock”，until的时态主要有一下2种：
如果是说将来的事，那么前面(主句)用将来时，后面(从句)用现在时
比如I won't leave until he comes back.
如果是说过去的事，那么前后都用过去时
比如I didn't leave until he came back.
不知你是否满意

Answer 2

上床睡觉是过去发生的，而且这个过去是相对现在而言，不是相对过去某个时刻而言，所以不选d

Answer 3

睡觉是短暂性动作WENT表示短暂 而D应该是长时间的 比如He had gone to Japan for3 years 他到日本去已经三年了
