老师好,我读到这样一个句子:
It was the first exoplanet to be discovered orbiting a star like our own.
这里的orbiting 是exoplanet的定语呢,还是在discovered 的后面省略了某个介词呢?
这里涉及的搭配是 discover sth doing sth(doing 为宾补)→(discover 变成被动式) be discovered doing sth(doing 为补语)。你的句子中的 orbiting 不是定语,而是补语,补充说明exoplanet;不定式短语 to be discovered orbiting a star like our own 才是定语,修饰 exoplanet。
例句如:
He was discovered hiding in the shed. 人们发现他原来藏在棚屋里。
The fault was discovered during a routine test. 这一缺陷在常规检测中被发现。
