1) many corporations are scaling back their operations and focusing on their core businesses (so as not to be hindered by over-diversification) in the world maketplace.
b: so that over-diversifaction would not hinder them
我认为两个都不对，答案为A。老白曾日：so as to 后不能跟被动，另外，so as to 主要用于系表结构。本题都不符，如何对？如果说B，时态也不对，哪位解一下？
2）at the civil war,most of the weaponry used in fighting (differed from that which had been used during )previous 100 years.
d:during 换成in
key:a
why?
in addition, which 一般不引导限定性定语从句，这是LZM强调的，是不是不一定对？DURING ,IN 有何区别？[em24]作者: tongxun 时间: 2002-6-1 16:38
1、一般说，so as to 主要用于简单的系表结构，这是没错的。但并不是绝对的！因为ETS的语法选项是找出最佳选项，而不是正确选项！
从这题来讲，后面被动用法是必须的，因为根据句仪应为：many corporationsas not to be hindered by ，而且如果不用被动用法，则by 就无承受者了。
注意：关于SO AS TO 中AS 的用法似乎还有他说，容我查证后再答复你，请注意翻贴！

一般来讲so that 首先考虑，但并不绝对！如此题B选项：so that over-diversifaction would not hinder them 。这里的so that 后是另起主语，这种情况下，使so that失去了他的普通意思了；导致我们必须要给that找一个referent。作者: success2002 时间: 2002-6-1 16:56
