问一道英语分词的被动形式的题_____ to sunlight for too much time will do harm to ones’s skin.A.Exposed B.Having exposedC.Being exposed D.After being exposed为什么选C?(要理由)
C 是动名词作主语.而且是被动形式的,所以being exposed
A是过去分词,虽有被动的意义,但分词不能作主语; B 表完成,但没有被动的意义; D 介宾,在这里语法错误,讲不通
长时间日晒会对皮肤对不利主语是being exposed to sunsunshine,谓语是will do harm to,宾语是skin,for too much time是定语。皮肤被晒伤,所以选择被动,所以是C或者D。但是D不能做主语,因为它前面是个介词,所以只能做状语。
句子缺少主语,只有动名词结构可作主语,句后为skin,需用被动语态。故选C。
