Question

1 The driver was badly hurt in the accident and he was sent to hospital immediately.
2 he goes to school
就这两句句子我想问一下第一个句子中的he was sent to hospital immediately中为什么要加个was?不是有谓语sent就可以了吗?就像第二个句子有goes不用is 可为什么第一个句子里要呢?

Answer 1

第一个句子中,was sent 是被动式的用法.被送往.,而不是他送别人去.
第二个句子,是主动式,他去上学.而不是“被去上学”
