问题描述:
新三17课中的两个语法问题They support the cables from which the bridge has been suspended
1,It has been estimated that if the bridge were packed with cars,it would still only be carrying a third of its total capacity.这里面的carrying 为什么要用现在分词呢,从句是一般过去时,主句应该用would加动原就行了,为什么用现在进行时
2,They support the cables from which the bridge has been suspended,为什么这个定语从句用完成时,这段的语态都是过去时时啊,为什么support用一般现在时,是对客观事实的陈述吗?那从句为什么用完成时呢
