The automotive conveyor-belt system, which Henry Ford modeled after an assembly-line technique introduced by Ransom Olds, reduced from a day and a half to 93 minutes the required time of assembling a Model T.
(A)   from a day and a half to 93 minutes the required time of assembling a Model T
(B)   the time being required to assemble a Model T, from a day and a half down to 93 minutes  
(C)   the time being required to assemble a Model T, a day and a half to 93 minutes  
(D)  the time required to assemble a Model T from a day and a half to 93 minutes  
(E)   from a day and a half to 93 minutes, the time required for the assembling of a Model T

答案是D 用being和require to就能选出来，但是有一点我有点看不懂

reduced  the time required to assemble a Model T from a day and a half to 93 minutes
required在这儿是做什么成分啊？如果是requied to就应该是动词啊，可是reduced已经是动词了啊，两个动词不是很奇怪嘛
如果required是修饰time的，那跟个to 在后面就很奇怪啊，或者是不是应该把required放在time的前面啊，就是reduced the required time,意为减少需要时间
不太明白，请NN们帮忙，谢谢

菜鸟来说说自己的理解。 required to assemble a modle-T 整个短语修饰time。 所以不能把required 与其他部分分开，单独放在time前面。

谢楼上
是说 required to assemble a modle-T其实是定语从句省略后的形式吗？
the time (that was) required to assemble a modle-T, that was啰嗦，省略掉直接用required to assemble a modle-T修饰
是这样理解吗

the time required to assemle a modle是不是？？？equal to =the required time to assemble a modle.这个句子的重心有没有发生变化？第一个句子重心在time，而第二个句子如果变成the required time to assemble a model, required 是adj，to assemble a model是补语吧？？？，所以不能把required提前

可以看成“the time that required to assemble a model"  required 修饰time 就比较明显了，其实就是省略掉了"that” 。这种用法在G中非常之常见，题做多了就没问题了。

我觉得required在这里应该是分词 用来修饰time的
