his latest book,Animal Liberation,sparked a nationwide debate .中为什么是sparked 而不是sparking

如果是sparking,这个句子就没有谓语动词了
这里sparked做谓语动词

sparked 是谓语,
his latest book sparked a nationwide debate
Animal Liberation 书名,插入语
要用ing形式没谓语了

sparked 是谓语,
his latest book sparked a nationwide debate
Animal Liberation 书名,同位语,解释说明的作用
要用ing形式没谓语了
