Question

______in the accident,Mr.black was sent to hospital at once and opearated on.

为什么填 badly injured？

Answer 1

过去分词作状语，表原因

______in the accident, Mr.black was sent to hospital at once and opearated on.

=For he was badly hurt, Mr.black was sent to hospital at once and opearated on.
由于布莱克先生在事故中受到严重伤害，被立刻送到医院做了手术

希望对你有帮助，满意请采纳

Answer 2

　　这里是过去分词作原因状语从句。过去分词短语作状语，其逻辑主语通常是句子的主语，与主语关系是动宾关系，即被动关系。 Mr. black 和 injure存在动宾关系。
　　如果改成：Because Mr.black was badly injured in the accident, he was sent to hospital at once and opearated on.
这样会不会更好理解？

　　如果满意，请及时采纳，感激不尽。
　　祝开心~！

Answer 3

Hello,
此处用的是ed过去分词，做状语，在这里省略了<he was> badly injured , 当从句的主语和主句一致并且有be动词时，主语和be动词可以同时省略，句子变得简洁明了。
此类的用法还有 <He was> ill, he didn't go to school.
Work hard when <you are> young, or you will regret.

Answer 4

应该是Mr.Black was badly injured in the accident，但是这种形式是要把Mr.Black was 省略的，

Answer 5

injured这里表示的是非谓语动词，因为Mr Black是被受伤害，所以要用ed形式。其真正的主语是was sent to 。
badly是用来修饰injured的，在这里是副词，表示严重地，厉害地的意思。
