The Helen Woodward Animal Center warned San Diego County residents Thursday to watch out for coyotes as the weather gets warmer, an announcement spurred by multiple coyote attacks and encounters in recent weeks.
请问老师们,这里的an announcemet在意思上我认为是指前面warned的内容,但是在句中是作什么成分呢?
an announcement spurred by multiple coyote attacks and encounters in recent weeks 这是一个名词短语,对前面句子内容作补充说明或解释。传统语法分析为句子同位语。即名词作前面句子的同位语。现代语法《剑桥英语语法》称其为补充语supplement,名词词组对前面句子作补充、说明。
