几个语法问题

tbs

1.OG SC 175. 解释说due to 和because 有不同,说due to synonymous with attributable to ,谁能具体地说一下吗?我们不是常常使用due to the reasons mentioned above吗?
2.177的解释中说as....as放句首的时候,main clauses following concessive clauses must express a contrasting notion:for example, "As ill-prepared as they are, they nevertheless find good jobs."我不理解这个contrasting notion 是指什么?我怎么没看出来有什么contrast notion啊?
3.12月的GMAT会特别的难吗?已经很没有底了...今天下午在教室里连续看了5小时的书,起来时突然看到后面位置上的一个男生刚刚在做OG,我差点有冲上去握手的冲动.扯远了...
谢谢

og175
due正式的用法是作为形容词, 即be due to, 作其它的方式使用不佳
总之是讲究正式的问题, 像similar也有类似的状况, ets不喜欢这样用
似乎没看过ets的题目中有例外的

og177
As ill-prepared as they are, they nevertheless find good jobs相当是
(Although they are) as ill-prepared as they are, they nevertheless find good job. 语意有问题

OG175：
请看下面一段对DUE TO的解释：
Due to has been widely used for many years as a compound preposition like  owing to, but some critics have insisted that the adjectival status of  due must be retained. According to this view, it is incorrect to say  The concert was canceled due to the rain, as opposed to the acceptable  The cancellation of the concert was due to the rain, where  due continues to function as an adjective modifying  cancellation.
所以在这个句子中，主语为many people,due to用在这里是unidiomatical的。

OG177：
解释讲的是 as...as 引导让步状语从句时，主、从句要有contrast notion。如例句中，尽管他们准备的不好，但是....。原句表达的是CAUSE-EFFECT的意思，不是although..,...的意思。
