Xiaohei was not in my sight.Perhaps he got down the bus at a

Answer 1

got down(谓语） at a stop by mistake（地点状语） looking for him（现在分词做主语） I did （做定语 修饰the whole thing） but it was a pity（另一小句） I would never see him again. 是 thought的从句 Outside the door stood my dog倒装句,而且是完全倒装,正常语序应是my dog stood outside the door,地点状语在句首时就要用完全倒装的句式 mud all over his body（over作谓语） could not help sobbing(can not help doing禁不住做某事 can not help to do不能帮忙做某事） from that moment on（固定词组 从那一刻起） have I understood（have用来强调语气）
