第二空at介词后跟宾语从句我懂,但第一空为什么After做介词,而不是做连词,做连词的话填it应该可以吧.老师解释过为什么这儿是做介词而不是做连词了,可惜想不起来了,知道的解释下.

解答

What seemed a very long time整体做介词宾语,宾语中缺少主语成分,所以用what假如After做连词用it，it seemed a very long time 这句子应该也对吧我觉得做连词从语法上这句子说不通，只能是做介词。当然如果after做连词用，仅从语法上说后面可以跟it seemed a very long time，因为它是个完整的句子，但意义上嘛就有点说不通。应该是这样吧，谢谢你啊
