题目内容：

请帮我解释下这个英文句子的中某个词的意思,
In a breakthrough that could prove hugely beneficial （prove后面为什么接的是形容词?）to divers navigating shark-filled waters,scientists found that the predator is unable to distinguish between colours,the German nature journal Naturwissenschaften reports.

优质解答

prove是个系动词,所以后面可以接形容词
动词后加形容词的情况:
1,动词是系动词
2,形容词和副词同形
