14.   With cloning technology, scientists are approaching what has long been the ultimate goal of modern husbandry: achieving a consistency of quality and production in farm animals as once thought to be limited to manufactured goods.

(A) achieving a consistency of quality and production in farm animals as once thought to be

(B) achieving farm animals with a consistency of quality and production as were once thought of as

(C) achieving in farm animals a consistency of quality and production that was once thought to be

(D) achievement of farm animals whose consistency of quality and production are the same as what were once thought to he（C）

(E) achievement of farm animals at a consistency of quality and production once thought of as

请问(A)如果改为achieving in farm animals a consistency of quality and production as once thought to be

是不是就正确了？

谢谢回复。忽然觉得红色部分不对。即使没有修饰歧义，这里的as用法似乎也是错误的。我印象中比较句在比较状语时可以用“as was expected”这种形式。比如：The cost was twice as much as was expected by experts.是可以的。

但是我不敢肯定下面的两句是否正确。

The book is good, as once thought to be.

You can read this book, as once though to be very difficult.

（You can read this book thought to be very difficult. 肯定正确）

欢迎讨论

The book is good, as once thought to be.

You can read this book, as once though to be very difficult.

（You can read this book thought to be very difficult. 肯定正确）

第一句话我认为正确，as once thought修饰主句主语book。

第二句话我认为错，as once thought指代不清，指代you还是book?

第三句话我认为语法上不错但读起来有点别扭，似乎写成You can read this book, which is thought to be difficult.更顺些。

彻底晕了。。
