Crossing the Domain伴隨狀語,邏輯主語是he
he主語
sat down謂語,也可以把down再拆成狀語,不過沒必要
suddenly 方式狀語
on a bench地點狀語
unnerved by the thought 過去分詞短語又是一個伴隨狀語,為這個想法感到焦慮
of the missus sitting up for him介詞結構作thought的后置定語,其中sitting up for him是現(xiàn)在分詞短語做missus的后置定語,和被修飾詞missus是邏輯主謂關系,“正在焦急等待他的那個婦人”
waiting to learn the outcome of the fight,獨立主格結構,邏輯主語是the missus
這個句子非謂語動詞的使用有點多,句子質量較高,但看起來麻煩,我給你拆成簡單句
He crossed the Domain,他穿過the Domain（地名）
and he sat down suddenly on a bench.突然一屁股坐在長凳上
He was unnerved by the thought of the missus.想到家里的太太,他覺得很焦慮
The missus was sitting up for him,太太一直在等著他
and the missus was waiting to learn the outcome of the fight.太太正焦急地等著戰(zhàn)斗的結果
看下每個動詞的主語應該就能懂了,樓主,我去把原文找來看了一遍,才能確定.
