請老師幫忙分析下這個句子的句子成分:grassland is destroyed without mercy so that dust storms come
grassland is destroyed without mercy so that dust storms come into being affecting distant cities.請老師幫忙分析下這個句子的句子成分.

解答：

句子的主句結構式Grassland is destroyed,意思是綠草地被破壞掉了, without mercy是狀語,修飾destroyed,表示無情的,so that dust storms come into being 是結果狀語從句,修飾主句Grassland is destroyed,意思是以至於形成了沙塵暴,affecting distant cities做伴隨狀語,修飾storms come into being,意思是影響到了很遠的城市.整個句子意思是,綠草地被無情的破壞掉了,以至於形成了沙塵暴,影響到了遙遠的城市.
