新三17课中的两个语法问题Theysupportthecablesfromwhichthebridgehasbeensuspended
1,Ithasbeenestimatedthatifthebridgewerepackedwithcars,itwouldstillonlybecarryingathirdofitstotalcapacity.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,Theysupportthecablesfromwhichthebridgehasbeensuspended,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
