有些该用“should+动词原形“的虚拟语气,有时将 should 换成了 shall 或 must,这还叫虚拟语气吗?或叫陈述语气?比如:
The law requires that all drivers wear a safety belt.
The law requires that all drivers should wear a safety belt.
The law requires that all drivers shall wear a safety belt.
The law requires that all drivers must wear a safety belt.
对于这四句,在现代英语中,严格说来只有第一句叫虚拟语气(命令性虚拟语气),其余三句都不是。 即:
The law requires that all drivers wear a safety belt.——命令性虚拟语气
The law requires that all drivers should wear a safety belt.——should 的推定性用法
The law requires that all drivers shall wear a safety belt.——陈述语气
The law requires that all drivers must wear a safety belt.——陈述语气
有些该用“should+动词原形“的虚拟语气,有时将 should 换成了 shall 或 must,这还叫虚拟语气吗?或叫陈述语气?比如:
The law requires that all drivers(should省略) wear a safety belt.(省略should的虚拟语气,属于美国英语用法,有人也称作为命令式虚拟语气。)
The law requires that all drivers should wear a safety belt.(带有should虚拟语气属于英国英语用法,有人也叫推定式虚拟语气)
The law requires that all drivers shall wear a safety belt.(陈述语气,属于情态动词表示命令式,强制性用法)
The law requires that all drivers must wear a safety belt.(陈述语气,属于情态动词表示命令强制性用法)
