请教D中的Shatter  是不是应该被动阿？ 因为觉得主语应该是20 percent of the leaf and small-stem material。求解

什么东东“shatters散落”“falls掉落”在地上怎么能用被动类。

as much as 是用来修饰20 percent的

而the是用来引导leaf and small-stem的，leaf and small-stem是用来修饰后面的material的，起形容词作用的。 插入的同位语 the most nutritious parts of the plant、修饰material。parts是部位、部件、零件的意思，不是复数形式。

所以后面的谓语动词的单复数形式是根据material来的，所以必须单数。

这样整个句子的单复数形式才解释的顺畅。

太精辟了 感谢你们俩

In the most common procedure for harvesting forage crops such as alfalfa, as much as 20 percent of the leaf and small-stem material, which is the most nutritious of all the parts of the plant, shattered and fell to the ground.

讲一个一般现象，用过去式不合适。
as much as是做单数。
the most nutritious part of the plant合适，因为是植物的一部分，所以part不能省略。

试析：
本题有两个知识点
1. 同位语
“the most nutritious parts of the plant” 是“the leaf and small-stem material”的同位语，显然从简洁的角度没有必要“the most nutritious of all parts of the plant”

2. 主谓一致
主语“as much as 20 percent of the leaf and small-stem material”作为一个整体似乎应该看成单数，请注意这里用的副词是“much”而不是“many”, 所以后面用单三人称
