There is not much time left,so I will tell you about it_____

问题描述:

There is not much time left,so I will tell you about it_____
A.in brief
B.in short
The answer is B,but I don't understand why.
我知道啊,in brief是简明的
in short是简言之,有什么区别?

翻译:"已经没有多少时间了,我要简短地将它告诉你."
而in short 是"简短的"的意思.
从句子语气来看,但从句所表现出来的感觉是很急促的,而,"in brief"是简明的,是使人简单地明白.强调的是明白.
而in short强调的是 时间上的短促感,侧重点不同.
