He will soon visit Darwin.He will visit Darwin__________________

问题描述:

He will soon visit Darwin.He will visit Darwin__________________
(A)quickly (B)for a short time (C)shortly (D)in a hurry
但是为什么b不行?soon是不久,for a short time不也是短期,短期不也就是不久么.

for a shorttime 也是短期但是,
它是用于过去的短期
而shortly跟在动词后面作副词又用于将来时
不是很对吗?
