Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
43. Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975. (B) and brings
(C) and it brings
(D) and it brought
(E) and brought
答案是A,因为离开鸟巢和变成34是同时发生的,这个比较好理解。
关于C和D官方解释是因为 it 没有指代对象。在这里为什么it不能看作是指代前面整个句子呢?就是前面整件事情使得数目变成了34?
