Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse. A. so hard that it makes burrowing difficult or so soft that it could cause B. hard enough to make burrowing difficult or soft enough as to cause (enough排除) C. as hard as to make burrowing difficult or soft enough so it causes (enough排除) D. as hard as to make burrowing difficult or as soft as to cause E. too hard, making burrowing difficult, nor too soft, so as to cause
我的疑问是，A要表达的句意是：“granitic soil不会硬到让burrow很困难的程度，也不会软到让tunnel collapse的程度” 而D表达的意思是：“不和to make burrowing difficult一样硬，也不和to cause tunnel collapse一样软”
而对于D现在我最大的疑问就中在，as... as...结构中，第二个as后面能否接"to make sth. difficult"这样的结构？ as...as...结构中，第二个as可以做介词+名词，比如She is as tall as me. 也可以作连词+句子，比如：She cooks as good as my mother cooks.
那这里"to make sth. difficult"能否充当一个名词性成分？如果不能，就应该是A了吧。。。
我觉得是这样。在A is as adj. as B这个结构里，最要紧的是第二个as 第二个as的出现就表明了，你是在对比两件事物，那就必须保证这个A和B是可比的，是同种的
The book is not as good to read. 这个as就是为了强调good的程度，而to read是我要说的动作。 而The book is not as good as that one. 第一个as还是为了强调good的程度，而第二个as就表明我是在比较两个东西。
那具体到The soil is not as hard as to make it difficult to burrow.... 这个第二个as的出现，明显就应该表明我是要比较两个东西了，可是"to make it difficult to burrow",暂且不管它是不是名词结构，它和那个soil都不是一个概念，不可比。这个才是最最主要的错误点~
而说到这个"to make it adj. to do"我觉得，做名词成分并不好，但是我不确定。所以以下内容，不一定对哈。。。。。。。。。。 我的理由是：这个to表达了一个目的，这个make又暗含了一个动作对象，所以这个结构应该是有一个逻辑主语的吧？~ 比如我们经常说To make the classroom cleaner, Jim swept the floor. 这样Jim的出现就明显的说明了前头那个词的逻辑主语是谁了~
