Studies show that in road accidents, people____unconscious due to____safety belts have a greater chance of dying.
A.knocking,wearing not
B.knocked,not wearing
C.knocked,not to wear
D.being knocked,not wear
答案是B,请问为什么?谢谢~~

knocked unconscious是现在分词结构作后置定语,修饰people
due to not wearing safety belts作补语,因为是due to结构,所以后面跟wearing,动名词形式

后半句缩写一下是:people (……)have a greater chance of dying

koncked 过去分词做定语充当形容词

due to+n./doing sth.

due to TO是介词,后接DOING

第一个空:PEOPLE (WHO IS ) KNOCKED

所以选B
