result of与 result from的区别

Two people died__his carelessness.
A. as a result of = because of

A
可以说as a result of ……或者result from……
但不可以说as a result from……
因此原题目也可以说成
Two people died result from his carelessness.

选B
第一个是指of 后面的结果。
the result of playing is that you will fail in the exam.
而result from 是指从from 后面得到的结果
the result from playing is that you failed in the exam.

这里是由于"carelessness[粗心]"得到的结果,所以要用"as a result from"
将句式调整可得:As the result from his carelessness,two people died.
