1.And on the topmost spray of the Rose-tree there blossomed a marvelous rose, petal following petal, as song followed song.

【难句解析】spray:长着蓓蕾或花朵的小树枝；the topmost spray:the highest spray。此句为倒装句。句子的主语是rose，谓语是blossomed，on the topmost spray of the Rose-tree作地点状语，there作on the topmost spray of the Rose-tree的同位语，as song followed song作方式状语，petal following petal 作插入语。倒装句分为部分倒装和完全倒装，此句为完全倒装。部分倒装只是把强调的部分放在句首，将主语和助动词或情态动词交换位置，句子的其他成分位置不变。

2.Bitter, bitter was the pain, and wilder and wilder grew her song, for she sang of the Love that is perfected by Death, of the Love that dies not in the tomb.

【难句释义】The pain became bitter and bitter and her song grew wilder and wilder, for she sang of the love that grows and grows until she died, and of the love that will live in eternity.

【难句解析】本句的前半部分是倒装句，主语是the pain和her song; for 后主语是she,谓语是sang of；在for 引导原因状语从句中，它的后面带有两个带定语从句的名词短语the love that...作宾语。
