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.

1. so hard that it makes burrowing difficult or so soft that it could cause

2. hard enough to make burrowing difficult or soft enough as to cause

3. so hard as to make burrowing difficult or soft enough so it causes

4. as hard as to make burrowing difficult or as soft as to cause

5. too hard, making burrowing difficult, nor too soft, so as to cause

答案居然是A,我觉得A不是一般的罗琐而是相当的罗琐

D,看起来很工整,而且我觉得as...as是用在肯定句和否定句里都可以的.so...as是只能用在否定句里的

谁看看

ding

这边的so...as to结构 = enough的含义，OG总结出来的enough永远错，别需用so as to/so that来代替，as....as to没有这个结构

切莫把as...as和 so...as 以及 so...as to搞混淆了

my thoughts,有不对的地方请指正

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   很完整的并列

A: so hard that it makes burrowing difficult or so soft that it could cause   很完整的并列

B:hard enough to make burrowing difficult or soft enough as to cause

C: so hard as to make burrowing difficult or soft enough so it causes

D: as hard as to make burrowing difficult or as soft as to cause

as hard as  和as soft as 和谁并列呢? 使用了as hard as 表示的是一种并列. 我们可以说 to build sth is as hard as to make burowring, 而不可以说 the soil is as hard as to make burrowing diffcult.

E: too hard, making burrowing difficult, nor too soft, so as to cause

我的观点：as hard as为同级比较，后面要有比较的对象。因此，不可能有as hard as to do的用法。如果要用as hard as，需改为as hard as soil that makes burrowing difficult。

而so...that可以表示结果。参见以前friend_friend的贴：

1. so as to ... = in order to ..., 它后面跟的不是句子, 在它后面部分的逻辑主语本来就在前面. 当然前后一至了.

2. so that ... = so + that 引导的从句, 没有要求过从句和主句的主语一致.

正如你指出, so that 有两重用法:

1) 相当于in order that, 即你所说的表目的. 如: I stopped so that you could catch up.

2) 相当于with the result or consquence that, 即你所说的表结果.

至于是表目的还是表结果,没有助动词,几乎一定表结果. 但有助动词时, 要根据句子意思来决定.助动词或情态动词不是判断的依据.例如:

I was just careless so that you could win this time. (我不过是大意了, 所以这次你才能赢的.)

需要提一提的是,解题分析里说 in order that they 的用法 imprecise and unidiomatic, 这么说是不正确的. C的错误在于they后面没有can没法表目的.如果这个选项是in order that they can, 那就完全正确了.

还要补充的是, 在现代口语及不是非常正规的书面文体中, so that 经常被 so 替代. 我没做过GMAT的题,不知道GMAT中的规律, 大家自己注意.
