have some difficulty 是用单数还是用复数

问题描述:

have some difficulty 是用单数还是用复数

用复数,difficulty可数

have some difficulties
difficulty可数,some用来形容可数名词。
短语如
be in difficulty 有困难
trouble也可数,短语如
a sea of troubles 困难重重
get out of trouble 摆脱困境

difficulty可数与不可数都行.“have some difficulty” 表示“有某种困难”,“have some difficulties ”表示“有一些困难”,意思不同!
have some difficulty in doing sth 是固定搭配句型
做...有某种困难

复数
