1. Something then happened which did terrible damage to their relationship.

結(jié)構(gòu)剖析：這是一個含有定語從句的復(fù)合句。主句是——Something then happened，從句是——which did terrible damage to their relationship。

它修飾先行詞something，這個先行詞是不定代詞，引導(dǎo)英語從句的關(guān)系代詞只能夠用that，不能用which。由于something在句子中做賓語，所以就把這個引導(dǎo)詞省略了。

此外，這個從句屬于分隔式定語從句，因為它長于謂語，所以置于句尾，以平衡句子結(jié)構(gòu)。

2. Dudley's wife, Amy, was found at the bottom of a staircase, dead from a broken neck.

結(jié)構(gòu)剖析：這是一個簡單句。主語是Dudley's wife，謂語是被動結(jié)構(gòu)was found。

其余的成分，Amy是做主語Dulley’s wife的同位語，說明其名字，at the bottom of a staircase是介詞短語做地點狀語。最重要的是dead from a broken neck是做伴隨狀況狀語。

3. .... it still cast a shadow over their relationship, just when they had become free to marry.

解析：when在這里不是連詞，是副詞，意思是“在這時候”，前面用了副詞just來修飾副詞when，加強語氣，意思是“就在這時候”。

4. Officially he was, and though the queen always insisted that Dudley had been vindicated...

解析：he was是與后面的讓步狀語從句公用一個表語vindicated，這樣顯得表達更為簡潔。
