题目内容：

这句英文该如何解释?
A year ago,overheated batteries aboard two Dreamliners prompted aviation officials to ground all 50 of the planes worldwide.
这句话的结构有点看不懂,到two Dreamliners 这里已经是完整的句子了怎么又来个动词prompted,而且后面的ground all 50 of the plans

优质解答

”overheated batteries aboard two Dreamliners“ 是主语部分.,“ground all 50 of the plans ” ground 是飞机降落时会,在这里是让全球的50架Dreamliners停飞的意思.
