1. 一般在否定句里面不用as as结构 用so as结构，as....as....只能用于肯定句中； 2. A is as adj. as B；A和B是性质相同的两个事物； 没有as adj. as to do的用法，只有so adj. to do

as……as is not usually shown in a positive sentence.

"as [adj] as to [verb]" is not a valid english construction. so (adjective) as to (verb) is a thing, but that construction doesn't figure in this problem. (it appears in choice C but is plainly not parallel to its counterpart.)注意句意，这里应该用so that。

1、as...as...表示什么和什么一样，要出现宾语。在这里意思不对应。 2、况且as...as...用于肯定句，so...as...用于否定句

一般来说只这种形式： A IS as hard to make burrowing difficult as B
chuster 2016-05-28 16:36:51
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",
