With the aid of the most advanced equipment,new facts about the ancient pyramids in Egypt
have recently        .
A.brought to light
B.seen the light
C.thrown light upon  
D.come to light
为什么选D 而不选A

bought to light如果前面是have been bought to light那 A 和 D都可以选了.
而have bought to light的用法应该是：XXX have bought ‘the new facts about the ancient pyramids in Egypt’ to light.
这里have come to light是被发现的意思,而have bought to light是动词,没有这个被的意思
